Youth Gems®- the very latest peptide based topical skin -aesthetic medicine- preparations
What tests have been conducted?
Clinical trials and examinations have been conducted at the St. Petersburg Biogerontology Institute and they have concluded that short chain peptides, when applied to skin cells, have many beneficial activities, shown below are some of those results:
The result of experimental research has shown that under action of the blood-vessel peptide the metabolism in vascular wall cells is restored to a normal level for each age group, this is despite of the action of negative influences, including environmental factors that otherwise promote accelerated skin aging.

How is each Youth Gem® application used?
Those who are already familiar with the work of Professor Vladimir Khavinson from the St. Petersburg Biogerontology Institute in Russia, will know how remarkable his work has been in the discovery of short-chain peptide bioregulators- located in food- that act as highly specific gene switches.
Now, four of these peptide bioregulators have been combined into topical skin preparations so that their performance can be brought to the field of aesthetic medicine; specifically the peptides in use are those from:
What does each peptide provide for?
The beauty product line Youth Gems® contains these peptides and a ginseng extract called Neovitin®. They are a specially developed program of complex skin care designed for the face, neck, hands and the body. The line includes four unique active ingredients of short-chain peptides that have a directed tissue-specific action to improve all basic skin structures, plus a ginseng biomass extract with strong antioxidant and anti-inflammatory action and a number of other natural and synergistic ingredients.
The green = normal skin antioxidant activity, orange = the antioxidant activity of skin under stress, red = antioxidant activity of stressed skin after pineal peptide application. The result of this trial confirms that the pineal gland peptide interferes with the otherwise destructive action of free radicals that are synthetized in skin- that can lead to premature skin aging. In fact, the antioxidant activity of skin cells is halved when under the influence of stress factors; however the application of the pineal gland peptide restores stressed skin to practically the same as physiological levels. Assessment of thermal radiation of the skin
This is an assessment of thermal radiation of the skin of volunteers before and after the application of Youth Gems®. It is known that skin elasticity depends on the microcirculation level in tissues and their moisture capacity. The conducted studies of skin microcirculation, (using a thermal imaging method) have found reliable variation in thermal radiation parameters between the control skin site and after the application of Youth Gems® within 7 days. The difference from the control parameter is a significant sign of improvement, showing that blood flow levels are increased under the influence of the Youth Gems®.
The left slide shows the human skin surface before the application of Youth Gems®. The right slide shows the same skin after the application of Youth Gems® for 2-months. It clearly highlights the considerable reduction of transverse and longitudinal striations; this has resulted in the smoothing of the skin’s surface, reducing the number of small wrinkles, increasing the skin’s elasticity and lifting the face contours. These beneficial effects were noted in 100% of women who took part in the voluntary clinical trial.
What else is included in Youth Gems® in addition to the four peptides?
In addition to the four peptides, the Youth Gems also contain an incredible array of beneficial natural agents- which just by themselves would make other antiaging creams jealous! The range includes:

It possesses effective anti-inflammatory action due to the presence of the thymus peptide and Neovitin®. Natural antioxidants within the serum effectively neutralize the negative action on the skin from free radicals, promoting a delay of skin aging. The cartilage peptide promotes normalization of collagen synthesis of skin cells leading to a smoothing of small wrinkles, improving skin micro-relief. The result is intensified by the active ingredients in Neovitin® and the formation of an elastic smooth film, under the influence of sweet almond extract, creates a ‘face lifting’ effect. The serum improves microcirculation in the skin with the help of the vessels peptide, optimizing the metabolic processes of the cells in the vascular wall and together with Neovitin®, the liposomes, vitamin C and rutin, they deliver active ingredients deep into the skin, thus improving skin nourishment and turgor. Youth Gems® serum intensively moisturizes the skin with the help of its specially developed moisturizing complex which is completed with a softening action.

Visoluten, vision and retina peptide complex supports vision health and performance by enhancing the quality of the retina, the cornea and the eye blood vessels. Visoluten® is the retina peptide bioregulator.
Prevents spasms, glaucoma, and cataracts
Angiopathy of the Retina
Prevent Retinal Degeneration and Detachment
Maintain the Functions of the Visual Analyzer
Spasm of Accommodation
The optimal function of the human visual organ is directly related to the state of the cells of the eye tissues - retina, lens, vitreous body and cornea. For the optimal function of the cells is their optimal supply of nutrients such as vitamins, minerals, and with peptides required. The peptides are components of the protein molecules and are released during protein metabolism (Disintegration of the protein into smaller fractions = peptides). The peptides are information molecules, which influence gene expression and start the process of protein synthesis. Formation of proteins is a vital process. This is necessary for the growth of the cells and performing its key features.
Visoluten includes the peptides obtained from the eye of young animal that improve the health of the visual analyzer by interacting directly with the retinal cells, the ciliary muscle and the conjunctiva. Peptides activate the synthesis of the specific proteins, capable of restoring tissues, damaged by a disease or with ageing. Treatment by Visoluten allows to reduce severity of complicated high myopia, pseudophakia and achieve significant positive dynamic in visual functions.
Visoluten eye extract contains natural peptides. These are molecules that play a key role in various biological processes in our body. They take care of information processing and transfer, as do hormones, by carrying messages from one tissue to another.
Fig. 3. Expression of transcription proteins (PAX 1) in human thymus epithelial cells (the study was conducted in cooperation with Prince Philippe Biomedical Research Center, Valencia, Spain).
In the 1970-ies we began investigation in the mechanism of immuno-depression both experimentally and clinically. We found out that with ageing there takes place an involution of the central organ of the immune system — thymus (Fig. 2, 3) and that of the neuroendocrine system — pineal gland. We also registered definite decrease of protein synthesis in cells of different organism tissues (Fig. 4).
To restore functions of thymus, pineal gland and other organs we developed a special method for isolation and fractionating of low-molecular peptides from extracts of these organs [24, 25].
On the organism level we have registered in different animals a significant variety of biologic effects exerted by small peptides especially by peptides of thymus (pharmaceutical “Thymalin”) and pineal gland (pharmaceutical “Epithalamin”) [3, 8, 13, 15, 36, 45, 46, 53, 57].

genes which regulate mechanisms of individual development and the onset of diseases .
The influence produced on gene expression permits correction of cell proliferation and differentiation decreased with age [26, 49]. The study of genetic mechanisms of ageing and development of age-related pathology underlies regulatory therapy — the employment of modulators of transcription, deterring and restoring genetically conditioned alterations occurring with age. It is important to know the genome, occurring disorders and to use substances producing selective effect on gene expression .
Designing of effective bioregulators which would contribute to the achievement of special life span limit and maintain major physiological functions constitutes a vital issue in modern biogerontology. Investigations in the problem focus on the role of peptides in prevention of premature ageing [36, 49].
Peptidergic regulation of homeostasis occupies an important place in a complex chain of physiological processes leading to the ageing of cells, tissues, organs and an organism in whole.
Morphological and functional equivalent of ageing consists in the involution of organs and tissues, primarily those referred to major regulatory systems — nervous, endocrine and immune ones. The data available suggest occurrence of age-associated hypoplasia, and in some cases even an atrophy of the pineal gland, thymus, brain cortex neurons and subcortical structures, retina, vascular wall, genital organs .

spontaneous and induced by irradiation or carcinogens (Fig. 6) [5, 9, 10, 16, 87]. It should be emphasized that this unprecedented decrease of tumour incidence was found in the majority of experiments (Table 1). Taking into consideration the general mechanism of carcinogenesis in all mammalians the results of these investigation have a great practical significance for tumour prevention in humans [10, 52].
Small peptides isolated from different organs and tissues as well as their synthesized analogues (di-, tri-, tetrapeptides) revealed a pronounced tissue specific (gene specific) activity both in cell cultures and in young and old experimental animals (Fig. 7).
Peptide tissue specific activity manifested in stimulation of protein synthesis in cells of those organs they had been isolated from. The enhancement of protein synthesis under the effect of peptide has been registered in young and old animals (Fig. 8).
Especially significant appeared restoration of reproductive function in old female rats subjected to the pineal peptide preparation treatment . Thus, estrus phase in animals, analogous to menopause in women, lowered from the initial 95% down to
52% after the drug administration, while other phases of the cycle, typical of the normal estrus, increased from the initial 5% up to 48%. Another experiment revealed that none of the old female rats got pregnant after mating with young males. Repeated mating after the administration of the pineal gland peptide preparation entailed pregnancy in 4 out of 16 animals which gave birth to 5–9 healthy off-springs each. Thus there were ascertained main advantages of low-molecular peptides as compared to high-molecular protein regulators: they possess high biological activity, reveal tissue specificity and are
For many years the phenomenon of ageing had been studied within the framework of ethics and social issues. Only in the last century the society realized that the process of ageing should be studied from a different viewpoint, that is, as a special physiologic mechanism bearing a certain evolutionary significance [26,30,67].
Ageing is the most complicate issue in medicine and biology. The process of ageing is a gradual involution of tissues and development of organism malfunctioning. Its symptoms appear already at the end of the reproductive period and become more pronounced with ageing .
At the end of the XIX century I. Mechnikov showed that enhancement of cellular immunity contributed to a lifespan increase. He developed a phagocytic theory of immunity and considered human organism capable of combating pathologic ageing . In 1908 he was awarded the Nobel Prize in Physiology or Medicine together with P. Ehrlich. And only one century later, P. Doherty and R. Zinkernagel conducted detailed studies in specificity of cellular immunity in case of viral infection (the Nobel Prize in Physiology or Medicine 1996).
J. Watson and F. Crick jointly with M. Wilkins were awarded the Nobel Prize in Physiology or Medicine in 1962 “for their discoveries concerning the molecular structure of nucleic acids and its significance for information transfer in living material”.
In 1961 F. Jacob and J. Monod suggested a model of genetic regulation of protein synthesis with the participation of low molecular ligand, which ousts repressor and triggers allosteric conformational transition in the DNA structure of bacterial cell . In 1965 they were awarded the Nobel Prize in Physiology or Medicine along with A. Lwoff. Many years of scientific work by M. Nirenberg and G. Khorana resulted in deciphering genetic code and defining codons (triplets of nucleotides) for each of twenty amino acids (the Nobel Prize in Physiology or Medicine, along with R. Holley, 1968).
Fundamental investigation in nucleic acids biochemistry and identification of RNA and DNA bases sequence were conducted in the 60-ies and 70-ies of the XX century by P. Berg, W. Gilbert and F. Sanger (the Nobel Prize in Chemistry, 1980).
Experimental and clinical studies in gerontology evidenced that immunity of the organism is among the first systemic functions to reveal disorders with ageing [22, 31]. Thymus peptide extracts and peptides, isolated from these extracts, were the first preparations suggested for immune deficit correction [21, 27, 29]. The origin of small regulatory peptides pool in a young organism became evident after the discovery of ubiquitin-mediated protein degradation in proteasomes made by A. Ciechanover, A. Hershko, I. Rose (The Nobel Prize in Chemistry, 2004). Small peptides were shown to play an important role for transmission of biologic information, as for example autocrine hormones and neuropeptides do. A high molecular protein can be hydrolyzed in different ways, degradating into several small peptides. Due to this mechanism there can be produced peptides with completely different biologic functions as compared to the maternal macromolecule . S. Karlin and S. Altschul proved in their works that there are several types of recurring blocks of amino acid residues with charged side chains in protein macromolecules. Nuclear proteins: transcription factors, centromere proteins, and HMG proteins — reliably contain the greatest number of such blocks . Proteasome hydrolysis of these proteins in the nucleus can provide presence of the sufficient amount of peptides with charged side chains.
However, the regulating role of small peptides had never been discussed in the concepts of gene control of protein synthesis in higher organisms before we started the research.
Alongside with immunity decrease associated with age there occur other alterations on cellular level. In particular, there take place changes in the inner structure of cellular nucleus. DNAprotein complex of cellular nucleus (chromatin) gets organized into chromosomes only in case of cell division. In stationary state chromatin is found in two forms: euchromatin and heterochromatin . Heterochromatin is usually localized in the nucleus periphery and contains generally inactive part of genome: genes blocked by repressors. The ratio euchromatin/heterochromatin changes with ageing due to reduction of active euchromatin. This leads to the decrease of protein synthesis in a cell .
Thus ageing phase of the organism reveals several levels of dysfunction and may be classified as a systemic syndrome. Promising results of immunodeficiency correction by endogenous regulatory peptides testified the necessity of further enhanced studies [27, 29, 31].
Discovery of peptide regulation of ageing
It is known that specific limit of animal and human lifespan is approximately 30-40% higher than their mean lifespan. It could be referred to the impact of adverse factors causing changes in the gene structure and expression accompanied by disorders in the protein synthesis and organism functioning (Fig. 1).
Specific limit of human lifespan — 110–120 years.
Recent achievements in theoretical and applied gerontology allowed goal-seeking regulation of ageing-associated alterations. Therefore, one of the priorities of gerontology today consists in prevention of premature ageing and age-associated pathology, finally aimed at the increase in an average lifespan, maintaining active longevity and reaching an upper limit of human life [30,51].
The integration of findings made by fundamental research into medicine resulted in a better understanding that clinical progress largely depends on molecular medicine, i.e. investigations conducted in genes and biologically active molecules. The achievements in genetics, molecular and cell biology often underlie molecular medicine in designing new pharmaceuticals and technologies.
The studying of genetic mechanisms of ageing is in the forefront of molecular medicine today. There have been defined
Peptide regulation of aging

In numerous experiments, these peptide preparations contributed to a reliable increase in animal mean lifespan up to 25–30% as compared to control [4, 5, 9, 16, 24, 25]. The majority of experiments registered some increase in the maximum life span. The most significant effect in the increase of the maximum life span was noted in CBA mice administered with peptide Ala-Glu-Asp-Gly. It made 42.3% . Of particular importance is a correlation between mean lifespan and the main index of cellular immunity
(reaction of blast-transformation of lymphocytes with phytohaemagglutinin) determining T-lymphocytes function in animals exposed to the effect of thymus and pineal gland preparations (Fig. 5) .
A significant increase in the mean lifespan of animals was evidently caused by a reliable anti-tumour activity of low-molecular peptides isolated from thymus and pineal gland which is confirmed throughout 55 experiments during 35 years. The animals manifested a sharp 1,4–7-fold decrease in malignant tumour incidence, both

On the level of cellular structures, small peptides activate heterochromatin in the cell nuclei in senile patients and facilitate the “release” of genes suppressed as a result of heterochromatinization of chromosome euchromatin areas (Table 2) [48, 74]. Structural condensation of chromatin is in close correlation with functional heterogeneity. Heterochromatinization is known to increase with age and correlate with inactivation of genes which were formerly active . Tightly condensed heterochromatin areas of chromosomes are genetically inactivated and replicate lately.
Decondensed (euchromatin) areas of chromosomes function actively. Active chromatin is obviously a necessary factor for gene transcription activity . As it was said above there are two forms of chromatin in the cellular nucleus: light euchromatin and dense heterochromatin located near nuclear membrane. Gene transcription takes place in the light phase, that’s in euchromatin. The amount of heterochromatin in the nucleus increases with ageing on average from 63% to 80%. Regulatory peptides entail the increase in the
Fig. 11. Overcoming human somatic cell division limit due to introduction of the peptide into the culture of the pulmonic fibroblasts.
Fig. 9. Induction effect of retinal peptides on the polypotent cells of Xenopus laevis early gastrula ectoderm.
Addition of small peptides to ectoderm polypotent cells in the same experimental model led to the onset of various tissues. These experiments showed that peptides are able to induce cell differentiation in regard to the structure of the substance added. The analysis of results obtained gives every ground to conclude that it is quite possible to induce deliberately differentiation of polypotent cells and to use biological reserve of various organs and tissues of the organism contributing to prolongation of life up to species limit.
The number of chromosome aberrations is used as a marker of DNA damages in an ageing organism. Somatic mutations can occur due to accumulation of stable aberrations and underlie age-related pathology, including malignant neoplasia . Reliable antimutagenic and reparative activity of thymus and pineal gland peptides have been confirmed by a reduction in the number of chromosome aberrations in the bone marrow cells and cornea epithelium cells in animals revealing accelerated ageing [14, 19, 49, 69].
On the level of gene activity regulation it was established that administration of peptides Lys-Glu and Ala-Glu-Asp-Gly to transgenic mice caused a 2—3.6-fold suppression of HER-2/neu gene expression (human breast cancer) as compared to the control group. This suppression is accompanied by a reliable reduction of the tumor diameter (Fig. 10) [15, 49].
It was revealed that addition of tetrapeptide Ala-Glu-Asp-Gly to the cultural medium of human lung fibroblasts induces telomerase gene expression and contributes to a 2.4-fold lengthening of telomeres. Activation of gene expression is accompanied by a growing number of cell divisions (by 42.5%), which is the evidence of Hayflick’s limit overcoming (Fig. 11) [40, 41]. This fact fully correlates with earlier stated maximum increase of animal life span (42.3%) after administration of this peptide .

neither species specific nor immunogenic. These features make regulatory peptides similar to peptide hormones [1, 4, 18].
A detailed study of molecular weight, chemical properties, amino acid composition and sequence of low-molecular peptides isolated from thymus, pineal gland and other organs had been carried out for many years [77, 78, 79, 80, 81]. The obtained data were used for chemical synthesis of several small peptides. A comparative analysis showed that biological activity of natural and synthetic preparations was largely identical. Thus, for example, thymus dipeptide Glu-Trp stimulated immunity, decreased ageing rate and suppressed occurrence of spontaneous tumours in animals [78, 80].
Biological activity of natural and synthetic peptides appeared to be similar in standard testing in tissue cultures and in animals [11, 12, 17, 42]. These results demonstrate prospects for application of these peptides as geroprotectors [37, 64, 71]. The necessity of searching for new drugs — geroprotectors dictated the onset of preclinical studies of these preparations on different structural levels.
Fig. 10. Peptides effect on the development of mammary adenocarcinoma and HER-2/neu oncogene expression in transgenic mice (the study was conducted in cooperation with the National Research Centre on Ageing, Ancona, Italy).
The effect of di- and tetrapeptides Lys-Glu, Glu-Trp, Ala-Glu- Asp-Gly, Ala-Glu-Asp-Pro on the expression of 15 247 murine heart and brain genes before and after peptides administration was studied with the employment of DNA-microarray technology .
In this experiment, there were used clones from the library of the National Institute on Aging, USA. This experiment provided unique data on alteration in the expression of different genes under the effect of peptide preparations (Fig. 12). An important conclusion driven from the experiment was that every peptide specifically regulates particular genes. Results of this experiment testify to the existing mechanism of peptide regulation of gene activity. It was also registered that dipeptide Lys-Glu, showing immunomodulating
amount of euchromatin in the nucleus. This means that more genes become available for transcription factors, and transcription of gene information goes on more intensively as well as protein synthesis.
In other words the more euchromatin there is in the nucleus, the more intensive the protein synthesis goes on in the cell [48, 74, 75].
These experimental results brought us to a conclusion that chromatin heterochromatinization is a reversible process which confirms a possibility of restoring protein synthesis, hence, organism functions .
The capability of peptides to induce polypotential cells differentiation is of special significance (Fig. 9) . Thus addition of retinal peptides to polypotential cells of Xenopus laevis early gastrula ectoderm led to the emergence of retinal and pigment epithelium cells. This outstanding result explains a pronounced clinical effect of the preparation of the retina in patients with retinal degenerations  and in animals with genetically determined retinitis pigmentosa .

activity, regulates gene interleukin-2 expression in blood lymphocytes .
On the molecular level, there was an obvious gap between multiple evidence of specific effects, caused by regulatory peptides in activation of gene transcription [6, 14, 23, 47, 52, 60, 69, 72, 84], and limited schemes of the process underlying the selective binding of the transcription factor with specific DNA sites. Meanwhile nonspecific binding of proteins with the DNA double helix was proved by physicochemical methods . Activation of gene transcription in cells of higher organisms as a rule needs dozens of macromolecular activators and transcription factors.
We proposed a molecular model of interaction between regulatory peptides and DNA double helix in gene promoter region (Fig. 13, 14, 15, 16) [63, 65].
Geometrical and chemical complementarity of peptide amino acid sequence and DNA nucleotide pairs sequence was assumed as a basis for the molecular model. Regulatory peptide recognizes a specific site in the DNA double helix if its own amino acid sequence is complementary to the DNA nucleotide sequence for a sufficient

sequences. Each sequence of the DNA double helix nucleotide pairs forms a unique pattern of functional groups on the surface of the DNA double helix major groove. A peptide in the unfolded - conformation can complimentary fit into the DNA major groove along the double helix axis. We used data on molecular geometry of the DNA double-helix and peptide -thread from scientific

publications in order to identify nucleotide pairs sequence for specific binding of the DNA and peptide Ala-Glu-Asp-Gly. The screening conducted showed that this tetrapeptide can be located in the DNA major groove with the ATTTG (or ATTTC) nucleotide sequence on the main chain in compliance with the complementarity of disposition of their functional groups .
For experimental testing of the molecular model there were used synthetic preparations: DNA [poly(dA-dT):poly(dA-dT)] (double helix) and tetrapeptide Ala-Glu-Asp-Gly. Gel chromatography helped to prove that peptide Ala-Glu-Asp-Gly forms stable intermolecular complex with the DNA double helix (Fig. 17) .
Complementary binding of the peptide with nucleotides sequence on the leading strand TATATA of the double helix can be conducted by six hydrogenous and one hydrophobic bonds between functional groups of both participants.
Fig. 16. Scheme of complementary interaction of tetrapeptide Ala-Glu-Asp-Gly with DNA double helix (“DNA-tetrapeptide” complex on the promoter segment of telomerase gene).
Under normal physiological conditions DNA exists in the form of a double helix two polymeric strands of which are kept together by hydrogenous bindings between pairs of bases of each chain.
Most of the biological processes with DNA participation (transcription, replications) need the double helix to undergo disjunction into separate strands. In particular, it is known, that local separation of double helix strands precedes gene transcription by RNA polymerase. For the transcription onset (synthesis of the matrix RNA) the DNA double helix has to be freed from histones,
Fig. 17. HPLC of peptide and DNA on sefadex G-25 in physiological solution at room temperature.

and in the place where the matrix RNA synthesis starts, the strands of the double helix should be separated (Fig. 18).
Concentration dependent hyperchromic effect (increased optic density 260 nm) was found by spectrophotometery of solutions containing synthetic DNA double helix and tetrapeptide Ala-Glu-Asp-Gly. The hyperchromic effect points out a partial destruction of hydrogen bonds between nucleotide pairs of the double helix and local separation of its strands (allosteric conformational changes) .
It was experimentally revealed that separation (melting) of free DNA strands occurs at the temperature +69.5°С. In the “DNAtetrapeptide” system melting of the double helix occurred at the temperature +28°С and was characterized by approximately 2-fold decrease in the values of entropy and enthalpy . This fact points out a thermodynamically simplified way of the DNA strands separation in temperature settings typical of biochemical processes of the majority of living organisms. Thus, DNA strands separation under physiological temperature is not a denaturation but a typical feature of protein synthesis initiation. In vitro experiments show that a small peptide of the definite structure and amino acid sequence can participate in activation of genes transcription on the stage of strands separation in the DNA double helix. Biochemical aspect of this phenomenon consists in similarity of structure and amino acid sequence of a regulatory peptide and a specific segment of the peptide chain of the macromolecular transcription factor.
Thus, the studies of peptides biological activity on different structural levels and of physicochemical processes of their interaction proved an indubitably high physiologic activity of peptide regulators and prospects for their further use. Major conclusion reads that peptides are capable of regulating gene expression. Pre-clinical trials demonstrated high biological activity and safety of synthesized peptides [35, 43, 56, 58].
Thus, the administration of peptides Lys-Glu, Ala-Glu-Asp-Gly to animals contributed to a reduced incidence of tumours and an increase in their mean lifespan [39, 82, 88]. Peptide Ala-Glu-Asp-Pro stimulated nerve regeneration , peptide Lys-Glu-Asp-Trp decreased blood glucose level in animals with experimental diabetes mellitus , peptide Ala-Glu-Asp increased osseus tissue density, peptide Ala-Glu-Asp-Leu contributed to the restoration of bronchial epithelium cells functions , peptide Ala-Glu-Asp-Arg restored myocardic cells functional activity .
There are still in progress studies of peptide preparations isolated from the cartilage, testes, liver, vessels, urinary bladder, thyroid, as well as synthesized peptides regulating functions of the brain, retina, immune system, proliferation and differentiation of polypotent cells. These physiologically active substances possess, as a rule, a substantial tissue specific effect and are obviously useful for designing new drugs on their basis applicable in bioregulation therapy .
Application of peptide bioregulators in monkeys. Taking into consideration a reliable biological activity of peptides we found it reasonable to study the effect of regulatory peptides in monkeys (Macaca mulatta) . Restoration of the melatonin level in old monkeys (20-26 years old) up to normal (typical for young animals 6-8 years old) following administration of the peptide preparation was among the most significant achievements (Fig. 19) .
The same old monkeys revealed restoring to normal indices of a daily rhythm of secretion of the main hormone of adrenal gland — cortisol (Fig. 20). Administration of the peptide or pineal preparation to old animals led also to restoration of glucose tolerance disturbed with ageing. Restoring effect of pineal peptides in respect to the function of the islet apparatus of the pancreas and

glucose metabolism is probably related to the restoration of both β-cells sensitivity to the glucose level in the blood and peripheral tissues to insulin) . Due to full correlation of mechanisms of ageing in primates and humans its seems reasonable to use pineal peptides in order to correct functions of the pineal gland producing melatonin, islet apparatus of the pancreas, and hypothalamushypophysis adrenal system in older people.
Application of peptide bioregulators in humans. Taking into consideration the encouraging data testifying to a high geroprotective activity of both natural tissue specific and synthetic peptide preparations we have been concentrating our attention on studies of geroprotective activity of peptides in old and senile people in recent years [7, 28, 36, 49, 52, 68, 70, 73]. Thus, annual treatment course with thymus and pineal preparations led to a reliable decrease in mortality during the period of observation (6–12 years) (Table 3), due to improvement of brain function and that of immune, endocrine, cardio-vascular systems, increased density

of osseous tissue (Fig. 21, 22) [36, 52, 68, 73]. It is noteworthy that application of preparation of the thymus led to a 2-fold decrease in frequency of acute respiratory disease (Fig. 23) . The restoration of melatonin secretion level in patients subjected to administration of preparation of the pineal gland is of special significance (Fig. 24) [68, 73].
Application of the pineal preparation in patients led to significant increase of anti-oxidation activity , organism resistance to stress factors, produced normalizing effect on carbohydrate metabolism.
Hypoglycemic action of the pineal preparation was conditioned by the increased insulin secretion
which combined with elevated sensitivity of peripheral tissues to insulin. Modulatory effect of the pineal peptide on the level of glycemia decreased along compensation of the disease. The patients suffering insulin-independent diabetes mellitus complicated by hypertension and treated with this drug revealed reduced arterial pressure and restoration of diastolic function of myocardium .
Women suffering climacteric myocardiodystrophy showed a significant therapeutic effect after administration of the pineal preparation which correlated with normalization of their immune and endocrine systems indices . The efficacy of the pineal preparation was registered in treatment of patients suffering aspirin asthma. They showed initially low content of melatonin, as well as patients with asthenia syndrome .
Thymus preparation revealed its efficacy in patients subject to thymectomy for thymus tumour. In 6-18 months after surgery, they

developed severe immunodeficiency which was evidenced by high incidence of respiratory viral infections, recurrent pneumonia, furunculosis, reduced ability of tissues to regeneration, signs of premature ageing (weakened skin turgor, intense graying, increased mass of fat tissue, disturbed functions of endocrine system, etc.).
These patients were treated with thymus preparation only. Following the course of treatment they revealed restoration of cell immunity, disappearance of furunculosis, increased muscular tonus. Later on there were registered lower incidence of viral infections and pneumonia. The treatment courses were repeated in 6-8 months.
These patients received thymus peptides both of the natural origin (drug “Thymalin”), and the synthesized one (drug “Thymogen”) during 15-20 years. It should be emphasized that application of thymus peptides appeared to be vital for them . Special value of this investigation consisted in identifying correlation of positive results with administration of thymus peptides to thymectomized animals.
Fig. 23. ARD incidence in elderly and old people treated with thymus preparation
The employment of thymus peptide preparations (drugs“Thymalin”, Thymogen”, “Vilon”) appeared efficient in treatment of many diseases and conditions associated with the decrease of cell immunity and phagocytosis: radiotherapy and chemotherapy in cancer patients, acute and chronic inflammatory diseases, massive utilization of antibiotics, in case of suppressed regeneration in posttraumatic period and in cases of various complications, in obliterating diseases of limb arteries, in chronic diseases of the liver, prostate gland, complex treatment of some forms of tuberculosis, leprosy .
Peptide preparation “Cortexin”, isolated from brain cortex produces considerable neuroprotection effect. This drug improves memory, stimulates brain repair and accelerates restoration of its functions after stress. The drug is used effectively in case of craniocerebral injury, cerebral circulation, viral and bacterial

neuroinfections, encephalopathy of various genesis, acute and chronic encephalitis and encephalomyelitis. The most pronounced efficiency of the brain peptide preparation is marked in old and senile patients .
Peptide preparation “Retinalamin” isolated from the animal eye retina shows vivid clinical efficacy. This unique preparation was created for the first time in medical practice and used in patients with various degenerative diseases of the retina, including diabetic retinopathy, involution dystrophy, pigmented degeneration of the retina, etc. The ability of the drug to restore electric activity of the retina correlated with the improvement of vision and appeared to be its great value .
A distinct effect was registered in patients after administration of a peptide preparation “Prostatilen” (“Samprost”), isolated from the prostate gland of animals. The drug proved to be effective in chronic prostatitis, adenoma, post-surgery complications and other age-associated urogenital dysfunctions.
Long-term studies and application of peptide preparations of the pineal gland, thymus, brain, retina of the eye, prostate proved their high therapeutic effect in patients of various age, however their strongest effect was observed in patients over 60. An obvious advantage of these peptide bioregulators-geroprotectors is an absence of any side effects. It is noteworthy that over 15 mln. people with different pathologies were treated with peptide preparations during the period of 26 years. Therapeutic effect was equal to 75-85% on average.
The results of clinical studies obviously prompt prospects for tackling demographic issues [51, 64].
Conclusion The mechanisms of ageing studies showed that an involution of the main organs and tissues of the organism accompanied by a decrease of protein synthesis in cells underlies the process of ageing. Peptide preparations isolated from organs of young animals when introduced into an old organism are capable of stimulating protein synthesis, followed by restoration of the main functions. Long-term application of peptides, both isolated from organs and synthesized from amino acid, was registered to lead to a reliable increase in animal mean lifespan by 20—40% i.e. up to their
specific limit (when peptide application started as a rule from the second half of their life). Small peptides (di-, tri- and tetrapeptides) revealed capability of complementary interaction with the DNA specific binding site on the promoter segment of genes, inducing separation of double helix strands and RNA polymerase activation.
Discovery of the phenomenon of peptide activation of gene transcription points out the natural mechanism of organism to maintain physiologic functions, which is based on the complementary interaction of the DNA and regulatory peptides.
This process is fundamental for the development and functioning of the living substance (Fig. 25, 26). Experimental data obtained
Fig. 25. The role of peptides in the cycle of DNA, RNA and protein biosynthesis.
serve as a confirmation hereto. Peptide incubation with the DNA leads to separation of its strands at 28°C and is accompanied with twice less values of enthalpy and entropy. Activation of telomerase gene expression was reached by incubation with the same peptide at temperature 30° C, and was accompanied by the increased fibroblasts divisions by 42.5%. Administration of this peptide to animals resulted in an utmost increase in their mean life span by 42.3%, which correlated with the phenomenon of increased division of fibroblasts.
Application of peptide bioregulators in humans for preventive purposes led to a significant rehabilitation of the main physiological functions and a reliable mortality decrease in different age groups during the period of 6—12 years.
It should be emphasized that this approach to the prevention of ageing is based not only on experimental and clinical data, but also
VENTFORT is a blood vessel peptide bioregulator used to purify, repair and boost vascular system's health and performance. It increases blood flow and strengthens the cells of the vascular walls. With age, the blood vessels become more rigid and are affected by atherosclerosis. As a result, vessels often cannot provide sufficient blood circulation to all tissues. Nowadays, coronary artery disease (hardening of the arteries in the heart) is the leading cause of death in both men and women. Moreover, in every case, there is some lack of blood supply involved. In order to heal the disease, blood supply must be restored, which is why supporting blood vessels is important.
The biologically active peptide bioregulator Ventfort provides regulation of blood cholesterol and lipoproteins contents and promotes improvement of vascular wall condition. Ventfort is well tolerated at oral administration, does not have any side effects, does not have any contraindication and can be used as an adjunct to complex treatment and prophylaxis of vascular disorders of various geneses.
Ventfort is recommended for improvement of the function of vascular wall in case of atherosclerosis, microcirculation disorders in the bodies and tissues art various diseases, influence on the organism of various extreme factors. It is also recommended to elderly people for maintenance of the vascular system function.
A report of the results of clinical study of the biologically active peptide bioregulator of blood vessel origin:
The biologically active peptide bioregulator Ventfort® contains a complex of low-molecular peptides with molecular weight up to 10000 Da, isolated from the vascular (aorta) tissue of young animals - calves aged up to 12 months.
Ventfort® is manufactured in the form of tablets or capsules with a content of active substances 10 mg.
Experimental studies have shown that the peptides possess tissue-specific action on the cells of the tissues from which they were isolated. They improve trophism of the vascular wall cells and provide regulating action on the metabolic processes in them, provide normalization of functional and morphological changes in the vascular wall, they regulate blood content of cholesterol and lipoproteins, thus decreasing a risk of various vascular defects. So it is possible to extrapolate an efficiency of use of Ventfort® for recovery of vascular function at various diseases, including vascular atherosclerosis.
Atherosclerosis and its consequences is one of the main causes of invalidation and death in developed countries. Age related changes of vascular wall and hemodynamic disorders results in decrease of peripheral blood flow, vascularization of bodies and tissues, development of various components of oxygen insufficiency and trophesies. (2, 3, 4, 6).
Drug treatment of atherosclerosis is aimed at normalization of lipid metabolism, blood coagulation processes and metabolism in the vascular walls (1, 5).
The clinical studies of Ventfort® were carried out at the Medical Center of the Saint Petersburg Institute of Bioregulation and Gerontology in patients with atherosclerosis of various arteries and senile purpura during the period from November 2003 till February 2004.
Clinical characteristic of the patients
The subjects of the clinical studies were 49 patients with arterial atherosclerosis and senile purpura, 27 of them were the main group (15 men and 12 women) - they were additionally prescribed Ventfort® per os 10-15 minutes before meal 1-2 capsules 2-3 times a day for 10-15 days depending on a degree of pathological process. 22 patients (11 men and 11 women) in the control group have been taking only general purpose medicines. The age of both groups of patients has made from 52 up to 84 years old (Table 1).
The patients of both groups have various clinical signs depending on affection of various caliber vessels: essential hypertension, ischemic heart disease, cerebrovascular disorders with memory impairment, clouded sensorium and affective liability. All the patients had progressive dynamics of pathogenic pathway.
All the patients have been taking symptomatic and pathogenic therapy for specific clinical signs of vascular pathology.
Distribution of the patients by clinical entities, sex and age
The patient complaints were assessed and compared, general clinical studies of blood and urine were carried out together with blood biochemical test using “REFLOTRON” device (Boehringer Mannheim, Germany). Blood coagulogram and tourniquet Hesse testing were carried out with a purpose of homeostasis assessment.
It was established that Ventfort® administration in patients with arterial atherosclerosis has resulted in improvement of general state of health, especially in patients with cerebrovascular disorders.
As you can see in the table 2, Ventfort® administration has resulted in reliable decrease in the level of general blood cholesterol. There were also a tendency towards decrease in the content of very little density lipoproteins, being most atherogenic.
The patients with senile purpura after Ventfort® administration had an increase in strength of capillary walls according to the results of Hesse testing, the frequency of hemorrhages has decreased. In most patients the skin and hair condition has improved.
Ventfort® administration has not resulted in any side effects, complications, contraindications and drug dependence.
Ventfort® is convenient for administration in hospital, out-patient conditions and at home.
Ventfort® can be used as medical and preventive mean in the form of biologicall active food additive in the form of adjunct for complex therapy of vascular atherosclerosis and improvement of microcirculation in different tissues in combination with any means of symptomatic and pathogenetic therapy.
The biologically active peptide bioregulator Ventfort® provides regulation of blood cholesterol and lipoproteins contents and promotes improvement of vascular wall condition.
Ventfort® is well tolerated at oral administration, does not have any side effects, does not have any contraindication and can be used as an adjunct to complex treatment and prophylaxis of vascular disorders of various geneses.
Ventfort® is recommended for improvement of the function of vascular wall in case of atherosclerosis, microcirculation disorders in the bodies and tissues art various diseases, influence on the organism of various extreme factors. It is also recommended to elderly people for maintenance of the vascular system function.
Thyreogen acts as a tissue specific bioregulator to regenerate, repair and restore organ functions. Thyreogen has been shown to help treat both hyperthyroidism, (weight loss, anxiety, heat loss etc) and hypothyroidism (weight gain, lethargy, cold intolerance etc). Also a poorly performing thyroid gland can lead to autoimmune thyroiditis.
Bioregulator Thyreogen - is a thyroid gland extract and contains the major peptides of the thyroid gland. For the extraction of peptides only thyroid gland tissue are used derived from calves and pigs younger than 11 months old. All young animals come from farms in which no diseases were registered, which are dangerous to humans, including BSE.

Professor KhavisoInterview with Vladimir Khavinsonn is president of the European Academy of Gerontology and Geriatrics (IAGG), advisor to various Ministries of Health and holds honorary distinctions from several universities.
Thyreogen - is a peptide complex, isolated from the thyroid gland of young, healthy animals. The isolated thyroid gland peptides have a selective effect on different cells of the human thyroid gland, normalize metabolism in these cells, regulate their functional activity and thus contribute to the regulation of the thyroid gland.
The optimal function of the human endocrine system is directly related to the state of the thyroid cells. For the optimal function of the cells is their optimal supply of nutrients such as vitamins, minerals, and with peptides required. The peptides are components of the protein molecules and are released during protein metabolism (Disintegration of the protein into smaller fractions = peptides). The peptides are information molecules, which influence gene expression and start the process of protein synthesis. Formation of proteins is a vital process. This is necessary for the growth of the cells and performing its key features.

Safety of Natural Peptide Bioregulators. – St. Petersburg: IKF Foliant, 2002. – 20 p.
The proposed scientific publication presents the results of a detailed study on peptide bioregulators isolated from animal organs and tissues and on the risk of their contamination with infectious agents, functionally active protooncogenes, nucleic acids, and prion proteins. The medical application of this class of pharmaceuticals has been proven entirely safe.
Introduction The contemporary epoch is marked by an extraordinary diversity of unfavourable factors affecting the human organism: natural conditions, unbalanced nutrition, environmental factors, external damaging agents including ionising and microwave radiation and toxic substances. It results in the depletion of adaptation and compensation mechanisms, occurrence of various diseases and pathologic states, and, finally, in premature ageing.
The above problems necessitate the development and clinical implementation of new effective therapeutic agents and the methods of functional correction, intensification of resistance to adverse factors, inhibition of ageing, and prolongation of life span.
Long-term experience of applying peptide bioregulators extracted from the organs and tissues of young animals has confirmed the high efficacy of this class of substances in various diseases and pathologic states including those not responsive to the treatment with other medications.
However, the active application of animal-derived peptide bioregulators in medicine requires special control over the quality and safety of these substances, since raw material used in their production can contain components hazardous for the human organism. In this view, it becomes ever more significant to devise technologies securing the safety of such substances and to work out effective control methods proving the absence of infectious agents, protooncogenes, prion proteins or other objectionable components in them.
natural peptide bioregulators The concept of bioregulation therapy based on the pathogenetic application of peptide bioregulators in various diseases, pathologic states, and ageing has been proposed and grounded in the course of 30-years’ research conducted at the Military Medical Academy (St. Petersburg) and St. Petersburg Institute of Bioregulation and Gerontology. Vyacheslav Morozov and Vladimir Khavinson were the first to isolate peptide bioregulators of multicellular systems from the hypothalamus, epiphysis, and vessel walls in 1971 . These substances have been brand-named cytomedins.
The technology of obtaining cytomedins includes acetic extraction of polypeptide fractions from cattle and pig tissues, their precipitation and subsequent multistage purification. The final product is in the form of lyophilised powder for injection solutions.
These developments have enabled the creation of new pharmaceuticals – peptide bioregulators, which form a group of pharmacologically active substances with molecular weight within 1-10 kDa. Their administration to the organism results in the functional restoration of the very organs, which the cytomedins have been isolated from.
The Institute possesses 15 pharmaceuticals. All of them have undergone thorough trials. Some cytomedins have been approved for clinical use over 15 years before (Epithalamin® – the endocrine system bioregulator, Thymalin® – the thymus bioregulator, and Prostatilen® – the prostate bioregulator) . In 1999, the Russian Ministry of Health certified the clinical application of Cortexin® (the cerebral cortex bioregulator) and Retinalamin® (the retina bioregulator) [15, 4]. Other bioregulators are undergoing various stages of clinical and experimental studies.
The technology of bioregulators manufacture and the methods of treatment with their use are covered by 70 licenses and USSR, Russian, and foreign patents. The majority of the developments have no analogues in the world.
Long-term experience of applying peptide bioregulators in healthcare has revealed their high effectiveness in various diseases and pathologic states including those not responsive to the treatment by other therapeutic means.
A new class of parapharmaceuticals – cytamins – has been created to expand the sphere for the application of bioregulators. Cytamins are balanced tissue-specific nucleoprotein complexes isolated from animal organs and tissues .
Today, 17 Cytamins are produced: extracted from the brain, liver, prostate, heart, thymus, bronchi, cartilages, pancreas, vessels, stomach, testes, epiphysis, thyroid, adrenal glands, kidneys, ovaries, and eye tissues.
Cytamins exert a targeted (organotropic) effect immediately upon the organs and tissues they have been isolated from. Being not drugs per se they produce a mild physiological regulatory influence on various functional systems of the organism, which enables their use as natural adaptogenes. Cytamins promote optimal functioning and full-value nourishment of organs and tissues, they do not contain any conservatives or other alien substances, produce no side effects, have no contraindications, and are compatible with any other nutrients and medications.
The patented technology of cytamins manufacture includes alkaline hydrolysis from tissue cells, consecutive precipitation of nucleoprotein complexes, their purification from ballast substances, and manufacture of the ready form as enterosoluble tablets or capsules.
Thus, two new classes of peptide bioregulators have been developed: pharmaceuticals cytomedins and parapharmaceuticals cytamins applied on a wide scale in medical practice to prevent various disease and pathologic states and treat for them.
safety of cytomedins and cytamins Historical background of the prion diseases concept
The history of the prion diseases concept is set forth in detail in monograph by V.A. Zuev et al. “Prion diseases in humans and animals” . Below we resort to some excerpts from this book.
The problem of prion diseases arose within the framework of the slow developing infections theory on the basis of the results of long-term investigations on mass diseases in sheep imported to Iceland from Germany in 1933. Despite some obvious clinical differences and uneven localisation of lesions in the animals’ organs and tissues, a principal similarity was revealed. This similarity can be summed up in four major signs of slow developing infections:
Among the studied sheep pathologies, scrapie was investigated. This disease of sheep and goats was well known in many countries.
Three years later, in a geographically opposite region – New Guinea – a new disease, now known as kuru, was revealed among Papua cannibals and described. Its mass development pointed at its infectious nature.
These and a number of other diseases were united by a common typical symptom. All of them were manifested only as lesions to the central nervous system: a typical picture of so-called spongiform transformation of the grey and/or white brain substances and, sometimes, of the spinal marrow based upon primary degenerative processes (without inflammation signs) and, in some cases, accompanied by the formation of amyloid plaques and expressed gliosis.
This peculiarity of the pathomorphologic picture marked out the name for the entire group of diseases – transmissible spongiform encephalopathies. Their pathognomonic feature consisted in the transmissibility of spongiform alterations solely within the central nervous system.
For decades, any attempts to discover pathogenes of these diseases ended in a failure though their infectious nature was convincingly confirmed. Yet, in early 80s Stanley Prusiner, an American biochemist from the California University, claimed that this pathogene was a nucleon-free low molecular protein (27-30 kDa), which he named “the infectious prion protein” . Prusiner proposed the term “prion” – an anagram from “proteinaceous infectious (particle)” as an infectious unit consisting of the infectious prion protein molecules. Prusiner was awarded a Nobel Prize in Biology or Medicine in 1997 for his prolonged investigations on slow developing prion infections.
Results of the studies carried out over the recent 15 years confirmed the prion nature of transmissible spongiform encephalopathy pathogenes completely. Consequently, these diseases were defined as prion ones.
The non-infectious (cellular) prion protein is vitally important. It is found in all mammals including humans. Among its distinguishing features is its high sensitivity to the digestive activity of protease K, which destroys this protein.
The infectious prion protein is preserved after the digestive impact of protease K. Its molecular weight equals 27-30 kDa.
The mechanism of accumulating the infectious prion protein in an infected organism has not been defined by now. At the same time, it is obvious that in a healthy organism the infectious prion protein entails the transformation of the normal prion protein into its infectious form due to the conformation changes of the normal prion protein. Therefore, the infectious prion protein is accumulated not via de novo synthesis of its molecules in an infected organism, but due to the conformation alterations of already synthesised normal molecules of a prion protein under the effect of the infectious prion protein.
The modern classification of prion diseases distinguishes human and animal pathologies and includes four human and six animal ones.
The list of human prion pathologies starts with Creutzfeldt-Jacob disease – the main in this group, while kuru and Herstmann-Streussler-Scheinker syndrome are considered to be its variants.
Scrapie is the main animal prion disease viewed as the prototype for all human and animal prion diseases.
In 1986, the United Kingdom was struck by an epizootic of bovine spongiform encephalopathy. As it turned out, the infectious prion protein originated from meat/bone flour. The technological process of its manufacture in early 80s implied a considerably reduced process of carbohydrate dissolving extraction of fat from bones, pluck, and heads of caws and sheep. This technological modification enabled the preservation of the infectious prion protein in raw material and caused mass contamination of ruminants after adding meat/bone flour to their forage as a protein supplement.
Started with two cases in 1986, the epizootic developed rather intensively and reached the peak of 1,000 cases in caws in 1992. Then the rate of new occurrences decreased notably and progressively.
Over this period, 23 sporadic cases of the so-called the new variant of Creutzfeldt-Jacob disease were registered, chiefly in the United Kingdom. The disease broke out among young patients, which was untypical.
Creutzfeldt-Jacob’s is a rare and fatal disease of worldwide distribution. Its total annual incidence in different regions is nearly equal and makes 0.3-1 case per 1,000,000 people. There has been revealed no correlation between Creutzfeldt-Jacob disease and the development of scrapie as the most frequent animal prion pathology. Creutzfeldt-Jacob disease has the same incidence in the scrapie-endemic United Kingdom and in Australia and New Zealand where scrapie has not been registered for years.
Wide-scale research was conducted in the United Kingdom in response to the epizootic of bovine spongiform encephalopathy in this country. Results of these investigations revealed the principal risk of infecting humans with prions from contaminated animals. It must be noted that the epizootic did not influence the total incidence of Creutzfeldt-Jacob disease in the United Kingdom as compared to other countries where no cases of the pathology in cattle were observed. Only the young age of all patients with the new variant of Creutzfeldt-Jacob disease attracts attention: all these people were less than 40 years of age. At the same time, young patients with this diseases constituted as little as 2 % of the total population (usually it was registered in the older age group, its peak striking the 60-65-year-olds).
Consequently, natural raw material of animal origin can potentially include infectious agents, protooncogenes, and nucleic acids. That is why, in the manufacture of preparations from animal organs and tissues a special attention is to be given to the purification of the active substance from objectionable admixtures and, first of all, to the infectious safety of such preparations.
Technological aspects of peptide bioregulators safety
In the manufacture of peptide bioregulators only the Russian-raised cattle is employed – calves and pigs under 12 months of age from the regions and farms where no human-endangering infectious diseases including transmissive bovine spongiform encephalopathy has been registered. It is to emphasise that Russia is known for its epizootological and epidemiological safety in respect to prion diseases.
The technology of obtaining cytomedins implies the acetic extraction of polypeptide fractions from calf and pig tissues, their precipitation and subsequent multistage purification until the outcome of active fractions with the molecular weight of 1-10 kDa. The final product is in the form of lyophilised powder intended for injection solutions.
The technology of extracting Cytamins includes alkaline hydrolysis of tissue cells, subsequent precipitation of nucleic complexes and their purification from ballast substances, drying of the half-product and manufacture of the ready form as enterosoluble tablets or capsules.
Thus, the patented methods of obtaining cytomedins and cytamins secure the maximal protection of these preparations from the interference of infectious agents. The active substance is extracted from animal organs and tissues at 3-7°C, pH 3.0 (cytomedins) or 11.0 (cytamins) for 6 days. These conditions are sufficient to fully inactivate all microbes and viruses even if no extra impacts are applied [8, 10].
Analysis of peptide bioregulators molecular weight
Molecular weight of cytomedins was studied by two methods – gel chromatography in Sefadex G-25 and electrophoresis in 15 % polyacrylamide gel. The results of gel chromatography revealed one peak in each chromatograms of the Cytomedins in the region of molecular weight under 10 kDa (Figures 1, 2, 3).
Testoluten acts as a tissue specific bioregulator to regenerate, repair and restore organ functions.
Low testosterone can result in depressed libido, erectile dysfunction, decreases muscle mass, depression, and depleted haemoglobin levels in the blood.
Testoluten - is a peptide complex, isolated from the testes of young, healthy animals. The isolated testes peptides have a selective effect on different cells of the male testes, participate in their cellular metabolism, support the regulation of their functional activity and thus contribute to the regulation of the functions of the testes and to increase the mobility of the sperm.

Extension of human life span is the most important objective of modern science. With ageing body regulating functions deteriorate and are accompanied by the immunity disorders and development of age-related diseases [1, 2, 7, 21, 33, 35, 37]. The ageing process is characterized with a complex of alterations due to impairments in many body functions, diminution of adaptive capacities, progressive growth of abnormal alterations and death probability. The causes and mechanisms of ageing are not quite clear as yet. A great deal of theories were suggested to explain some or other ageing mechanisms [30, 34]. According to one of them ageing is caused by accumulation of pathologic alterations in the body, and the rate for such an accumulation might be influenced by genetic factors as well as by environmental conditions [11, 12]. An issue of health maintenance and longevity consists mainly in utilization of natural body reserve capacities. Therefore, issues regarding implementation of the very own body biological potential are still of current interest being key objectives for gerontology in general and geriatrics, in particular . One of the priority trends of current research in gerontology is a concept of biological regulation (bioregulation) suggested and proved by V. Kh. Khavinson and V. G. Morozov [25, 26, 27]. The bioregulation as per up-to-date notions proceeds on several levels such as supracellular, intercellular, intracellular and molecular. The bioregulation mechanisms in spite of multilevel hierarchy perform a single task to coordinate processes of biosynthesis, interchanging and reproduction of genetic information. The bioregulation unites all control mechanisms in a pluricellular organism .
Multiplicity and complexity of the regulating processes suggest presence of universal mediators for information transmission to a cell. Such mediators are peptide bioregulators that exist in different tissues and reveal a wide range of biological activity. They participate in intercellular interactions by transmitting information recorded through corresponding amino acid sequence from one cell to another . Another and not-the-least objective for gerontology is to pursue for new means of the ageing inhibition and life-span extension (the so-called geroprotectors). Development of new therapeutics based on endogenous physiologic active substances produced by a body is a novel approach for restitution of functions lost with ageing .
One of the recent discoveries consists in obtaining from animal organs and tissues of the peptide bioregulators, cytomedins . Firstly the cytomedins were obtained from hypothalamic area of the cerebral cortex, pineal gland, thymus and vascular wall [25, 26]. Later peptides similar in origin and physical-chemical properties but different regarding functional activity were found in other body tissues, as well [23, 41, 42]. At present class of peptide bioregulators enumerates several dozens of known compounds and their number increases constantly. As per chemical composition they are complexes of polypeptides having molecular weight of 1000 to 10000 daltons. After experimental and clinical studies of cytomedins there appeared possibility for preventive and therapeutic application of peptide agents to enhance body resistance to impact of negative environmental factors. These researches admit development of new therapeutic agents containing peptide bioregulators of pineal gland (Epithalamin®), thymus (Thymalin®), prostate (Prostatilen®), brain cortex (Cortexin®), retina (Retinalamin®), etc. [23, 25, 26, 42].
Last years among the agents of bioregulation therapy another new class of therapeutics generally named as cytamins and being biologically active nucleoprotein complexes extracted from animal organs and tissues appeared. The said medicines relate to parapharmaceuticals and can effectively restore altered functions in organs they were extracted from [22, 43].
Normalizing effect of peptide bioregulators on the functions of various organs and tissues was found. One can note one of the mechanisms of <> activity of peptides, namely, participation of cytomedins in regulation of cell proliferation and differentiation, as well as capacity of the self-regulation regarding the number and functional activity of cell elements in population [18, 27]. Therefore, one can suggest that peptide bioregulators might affect tissue morphology restituting their altered structure.
To prove the aforementioned mechanism of action for the peptide agents the clinical study of influence of cytomedins and cytamins on normalization in structure of abnormally altered tissues in parenchymatous organs.
Until now, the pursuit of anti-aging medicine was to slow the aging process, let alone halt it. But earlier this year, a groundbreaking study published in the journal Nature showed that it’s possible to reverse the infirmities associated with aging and regenerate deteriorating tissues and organs by rebuilding particular portions of DNA at the ends of chromosomes, known as telomeres. This unprecedented finding is supported by a growing body of research demonstrating that ensuring the integrity of telomeres, these small segments of repeating DNA which would otherwise decay over time, wreaking havoc on multiple tissues and organs, may hold the key to longevity. TA-65®, an innovative product developed by biotech company Geron Corporation, has been shown, through many years of development and testing, to maintain the structure of telomeres in animal and human cells. Previously prescribed only by medical professionals, this cutting-edge product is now available from International Antiaging Systems.
Eroding telomeres and the Ticking Clock of Aging In the 1960’s geneticist Leonard Hayflick made a discovery crucial to our understanding of the mechanics of aging: human cells cultured in his laboratory divided only a finite number of times. Why was this observation relevant to aging? Because cell division ─ a fundamental process that enables a cell to copy its DNA and chromosomes and duplicate itself ─ is not only necessary to growth and development, but also to the repair and maintenance of tissues throughout our lifetime. Once cells stop dividing, they malfunction and die, leading to tissue and organ degeneration, aging and age-related diseases such as cardiovascular disease, Parkinson’s, Alzheimer’s, cancer, and atherosclerosis. It took about another decade before scientists were able to determine why cells stop dividing after they reach their quota of divisions ─ and evidence pointed to a DNA replication problem involving telomeres. During cell division, the DNA at the telomeric ends of chromosomes can’t always completely copy itself (comparable to the way a tape recorder can’t record sound at the very ends of the tape), resulting in a progressive loss of DNA and shortening of the telomere with each repeated cell division. Once telomeres reach a critical length or shortness, cells stop dividing, which, as we have seen, sets the stage for the deterioration of the body’s systems of defense, repair and maintenance, leading to organ decline and disease. What’s fascinating is that this progressive shrinking of telomeres ─ this genetically programmed, ticking clock of aging ─ is observed in somatic (body) cells and stem cells, but not in reproductive cells, which have the capacity to divide indefinitely and maintain telomere length with each cell division. What factor operates to maintain telomere length and cellular immortality in reproductive cells that is turned off in somatic cells? The activation of a specific gene that turns on the production of the “immortalizing” enzyme telomerase, enabling the entire strand of DNA, including the ends, to be replicated during cell division, so that telomeres maintain their length, providing for unlimited cell division potential. And can this gene be turned on in somatic cells otherwise subject to a finite life span? Miraculously, research has confirmed that the answer is yes.
TA-65®: Rewinding the Ticking Clock of Aging Studies demonstrate that telomerase activator TA-65® turns on the gene to stimulate telomerase production and lengthen telomeres in animal and human cells. TA-65® is a natural product, a purified extract of the root of Astragalus membranaceus, traditionally used in Chinese medicine. Harvested from select farms in a small area of China, the active ingredient is extracted, concentrated and purified at an FDA-certified laboratory to produce a product at least 95% pure in TA-65®. As mentioned, the product was originally developed at Geron and then licensed to its current manufacturer, T.A. Sciences in New York in 2002 where it underwent five further years of research.
In vivo studies in animals and humans shows that TA-65®, rather than increasing average telomere length, preferentially elongates the shortest telomeres. In other words, TA-65® rescues those telomeres which are critically short and most at risk for causing impending cellular decay and mortality. In addition, TA-65® exhibits a positive, age-reversing effect on the immune system, producing more youthful levels of tumor-destroying and virus-targeting white blood cells. TA-65® also improves age-related indicators, such as glucose tolerance, skin quality and sexual function. In addition, the product is safe – not one adverse effect has been reported in the hundreds of people who have taken it at the recommended dosage, nor was any ill effect observed in animal studies (quite the opposite: a rejuvenating effect was produced in the vast majority of cases).
We’ve seen that the effects of diminished telomerase production are drastic, resulting in shortened telomeres, arrested cell division, and its consequences: aging and age-related diseases. For the first time, a proven regenerative strategy that acts at the DNA level is commercially available from International Antiaging Systems. TA65® is the only product on the market that has been researched and demonstrated to activate the gene for telomerase production and lengthen telomeres. When it comes to anti-aging regimens, TA-65® is the state of the art in restoring and rejuvenating cellular function, and ameliorating, even possibly preventing, the functional decline associated with growing older.
