The development of new highly effective medicinal preparations was always a zone of the intent attention for the leading pharmacological firms of the world. Despite an enormous variety of the medicinal preparations a search of universal mechanism influencing on the human body becomes especially actual on the border of new century.
One of such directions in the field of highly effective medicinal preparations of the new generation are Erbisol preparations, developed by the Scientific Production Center "ERBIS" (Kiev, Ukraine).
Erbisol preparations are characterized by the original mechanism of the action. This mechanism allows them to affect not so much a disease as the whole body activating the body's control systems responsible for the search and elimination of pathological changes. The immune system is one of such main control systems.
The preparations targetly activate the immune system which effectiveness is first of all manifested through the effect of macrophage link promoting the repair of damaged cell and restoration of functional activity of organs and tissues as well as through N- and T-killers responsible for the elimination of abnormal cells and tissues.
The fundamental examinations of regenerative processes in animal organs and tissues with different kind of damages were a basis for the development of principally new methods influencing the restoration of organ and tissue functional activity under the pathologic changes. The regenerative process, as is generally known, is broadly developed in lower organized animals. For example, if the worm is cut in half the two new ones will grow (restore) from two parts. The claws grow in a crab, the pads - in a triton, the tail - in a lizard but the birds and mammals are devoid of such possibility. Did they lose such ability really or is it blocked or in somnolence state in the course of evolution and is only manifested at the level of wound healing, restoration of dermal and hairy integument, epidermis of intestine and other cells that are constantly repaired in the process of body vital activity?
But the search of a key for starting the organ and tissue regenerative processes can approach the treatment problems of pathological foci in a principally new fashion. No strive for curability such foci as many as the substitution for the healthy tissue by accelerating the regenerative processes of damaged cells and the elimination of abnormal cells and tissues inflexible for the regeneration and also the activation of hypertrophy processes and proliferation of healthy neighboured cells substituting for the necrotic foci. Further more, activating the regenerative processes in the elderly the functional insufficiently of the organs can be restored by modulating the process of "rejuvenation" of the tissues and in that way can be found a different approach to the problem solution of an active longevity.
A dream is excellent but how get it near? But now the nature itself gives us a prompting.
It appears if the 2/3 part of the rat liver is almost cut, the new liver is nearly grown in full volume from the part remained next day. Notice, this is occurred in higher organized animals and such increased regenerative speed there is not accessible even to the lower organized animals as a worm cut, the crab claws, the triton pads, a lizard tail are recovered during some months. Certainly, the rat liver regeneration is different from that of organ regeneration in these animals but nevertheless it indicates that higher animals did not lose this property.
Studying the rat liver regenerative process, an appearance of "new" antigens such as the protein molecules, absent in norm, that change immunogenicity of regenerative tissue, thereby activating the animal immune system, on the surface of remained liver hepatocytes (basic functional cells of the liver) in 4-5 hours after hepatoectomy of 2/3 parts was revealed by us. In this case the very ancient link of the immune system - macrophages - are first responded to the appearance of such "new" molecules. In the liver they are presented by the Kupffer cells. If at that instant they are neutralized by the administration of Indian ink, colloid iron or gold into circulatory bed the regeneration will be absent
Many of these autoantibodies are the immunoglobulins characteristic for the growth processes with specific structure of Fc-fragment4-5 that has probably no small importance in their fixation to the immunocompetent cells taking part in nonspecific immunity and playing the role of their receptors while contact with typical antigens.
It is interesting to note that macrophages were for the first time discovered by I.I.Mechnikov who tried to resolve the problem of human longevity with their help. Indeed he was on the way to this resolution. However it becomes clear just now but at that time this was considered as an imagination of the old man. His experiments were carried out on the monkeys. This is very interesting history: he had meeting with a millionaire advanced in age who wanted to be included into the experiment and to be rejuvenated in the spirit of science fiction of that time.
The scientist was subsidized by that man: all the monkeys were purchased by him. The trouble was that I.I.Mechnikov started to carry out his experiments in France at 1st world war. The soldiers of Germany came up to Paris, the capital of France, the projectiles began to fall into the town. The authorities of Paris were afraid if the projectiles will hit into the breeding nursery with infected monkeys (scientist attempted to force the macrophages to work whipping up them with infection) they will scatter along Paris and will cause the epidemic. The people of France made in the spirit of war-time: a detail of soldiers arrived and the precious monkeys were shot in sight of the investigator. I.I.Mechnikov could not bear it and he was soon died, and the idea was for some time forgotten - so it was not at that time comprehended by nobody. But we could have such medicine already at that time.
Something was not enough in all that. Really infecting body I.I.Mechnikov "whipped up" the macrophages but started the very strong additional side-processes. It was obviously necessary to go by other way - many of these things became clear while it was detected that our "repairing" system includes no a link but two ones at least. Firstly the macrophages attempt to "repair" the damaged cell and if it is not succeeded an another line is going up - "killers", the special cell-killers destroying the hopeless ill cells.
It is particularly necessary to underline that millions
of cancer cells are daily born in everybody of us. It is unimportant
what is a cause of their appearance: are there a result of the cancerogenic
substances or radiation, or virus. Probably, every of these causes
is collected its part of the sacrifices which ration is dependent on
the oecological peculiarity of the given medium. All these cancers,
mutant cells, virus carries and other irreversible pathologically changed
(anomalous) cells have to be destroyed by the immune system without
mercy. Namely the principal task is in this but not in the fight against
an external infection as it was early considered over a long period
of time. The cell-killers that are present in the body by two lines
are responsible for this function:
But, let us come back to the regenerative liver. There
are the cancer cells in the remained part of organ that have to realize
more quick reproduction during its intensive growth in comparison with
the healthy cells, and the regenerative liver has to reduce into cancer
Thus, we discovered an appearance of the "new" antigens which are in a norm absent during the damage of organs and tissues and are called for the immune system helping. Just these "new" antigens discovered by us became an object of our intent study.
Such markers are present on all the cells (they were not
found by us only in erythrocytes that as is generally known didn't
react and perish at any damage) and help to reveal the pathological
processes by the immune system.
The cells of macrophagal series that initiate the reparation of damaged cells and start the regenerative processes of organ tissue are the first immunocompetent cells reacting on the immunogenicity change of such "markers of cell physiologic state". Slightly later N-(natural) killers destroying the irreversible, damaged cells that are defying the reparation or anomalous cells arised as a result of mutations, anomalies in the genetic code, neoplasia and cells of virus carrier and so on are activated. Therefore, it is no coincidence to discover the malignant and mutant cells in the regenerative organ despite the high degree of risk This is practically difficult to realize. Later the immunocompetent cells responsible for the realization of specific immunity are activating.
If such "markers of cell physiologic state" are isolated from tissue with proceeded processes not peculiar for normal state and "signal" glycopeptide section is chosen after corresponding treatment necessary for the elimination of side effects, so inserting it into other body we insert the trouble signal (alarm) provoking the immune system to the search of pathological processes. Under pathology the complicated chain of mechanism for its elimination is started by the above said activated immunocompetent cells.
Besides the activation of unspecific immunity as macrophages and N-(natural) killers, "signal" molecules isolated from "markers of cell physiologic state" stimulate specific immunity and in accordance with the expression analysis of leukocyte specific antigens activate T-helpers and T-killers of the cell immunity predominantly. Moreover T-suppressors are simultaneously activated that is accompanying with the inhibition of B-lymphocyte humoral immunity.
At that time in patients with deficiency of humoral immunity T-helpers and B-lymphocytes are activated and the state of immune system is corrected in that way depending on patients status. The subsequent influence of the specific stimulus (antigen, infection, vaccine and so on) allows to develop the more effective specific immunity and consolidate the immunologic memory.
Especially it is necessary to emphasize that preparations on the basis of such "signal" molecules manifest their action in full measure only in the presence of pathologic process and in a case of its absence the activity of stimulated immunocompetent cells is already normalized in 2-3 days after preparation administration without any negative consequences for the body.
Thus, after a preliminary treatment for the purpose of preventing some side-effects, "markers of cell physiologic state" became the main functioning source of Erbisol drugs6. Erbisol drugs contain non-protein complex of natural organic compounds of non-hormonal origin isolated from embryonic tissue of chicken or duck germs.
They contain the specific "signal" low-weight molecules isolated from "markers of cell physiologic state" which activate natural evolutionally formed mechanisms of a search and elimination of pathological changes in body and tissues and promote more full realization of body genetical potential. The drugs induce the synthesis of interferon and factor of tumor necrosis.
In this connection unlike other remedies that are widely
used in the medical practice a peculiarity of the preparations developed
in SPC "ERBIS" is their ability:
The results of scientific researches obtained by SPC "ERBIS" found
their technical realization in the developed drugs that were patented
with 2 patent as "Biologically active substance, method of its
production and preparations on its basis" in the Ukraine (Patent
N 2161, N 2164) and in Russia (N 2041715, N2041717) and also in 18
countries of the world with international claims (PCT/UA 93/00003 and
hepatitis of various aetiology8,9, including medicamentous hepatitis (for example, provoked by the usage of antibiotic agents or chemotherapy), and virus hepatitis10, hepatocirrhosis, hepatosis, erosive ulcerous diseases of gastrointestinal tract, paradontium11, in therapy of diabetes mellitus12, bronchial asthma13, oncologic neoplasms14.
In virus hepatitis* Erbisol inducing the interferon synthesis and activating T-helpers promotes the elimination of virus itself as well as the cells of virus carrier where virions are developed. The titer of virus antigens was significantly decreased and patients with critically degree of disease were already passed into the mild form in 10-15 day. According to this index Erbisol is more effective than commercial Interferons. Our drug is also more effective than Essenciale in the next phase of the liver regeneration.
Erbisol increases sufficiently the effectiveness of the
treatment of hepatocirrhosis including the ascitic forms of "hopeless" patients.
At the same time, the clinic of oncologic diseases is one of the special directions developed in our Center.
The results of preclinical examinations carrying out at the Institute of Pharmacology and Toxicology of AS of Ukraine shown that Erbisol inhibited the growth of 5 types of experimental malignant tumors up 70-90% and suppressed metastatic spreading completely.
Erbisol activates T-killers (basic acting chain in oncologic diseases) directly and inhibits humoral immunity (that is promoting the target cell screening from the elimination by T-killers that determined the principal cause of unsuccessful usage of so-called "total" immunomodulators in Oncology that stimulate humoral immunity in oncologic patients).
An effectiveness of Erbisol and that of new preparations on its basis is explained by its ability for increase an interior potential of the immune system during prophylaxis and treatment of malignant neoplasms but when the tumor development goes to far the immune system can not independently resolve a given problem the necessity in combined chemo-, radiotherapy and oncosurgery with classical methods of treatment is appeared.
It is known that the tumor as well as the liver and the immune system are affected during chemotherapy that excites the apprehension of the use of intensive, effective treatment course. In this plan Erbisol is excellent hepato- and immunoprotector. Indices of the state of the liver and the immune system were even improved after chemotherapy against a background of Erbisol usage without a decrease in the efficiency of course itself. At radiotherapy the non-healing suppurating wounds could be appeared in the site of treated tumor for some months. Usage of standard reparants promotes their healing and also the growth of malignant cell which were remained. Erbisol has more quick influence on the wound healing and activating T-killers promotes the elimination of tumor cells remained. Here as well as in oncosurgery Erbisol is used as reparant and immunomodulator.
Erbisol as a preparation of accompaniment during chemo- and radiotherapy improves significantly effectiveness of treatment in two directions. First of all as a reparant, hepatoprotector and immunoprotector it defends the healthy cells and tissues from chemical and radiation injuries, restoring damaged links where macrophages play a significant role. It allows to use the more strict scheme using chemopreparations with violent effect and radiation doses without the special negative consequences in the patient state preventing moviting and the hair fall-out. Secondly as immunocorrector it restores antitumorigenic functions of the immune system and in spite of destructive effect of chemo- and radiotherapy contributes to the improvement of patients immune status up to that of practically healthy persons. In contrast to standard "bare" chemo- and radiotherapy this permits to include the protective antitumorigenic functions of the organism into the periods between courses that influences on subsequent improvement of the level of life quality, permits the substitution of some courses of chemo- and radiotherapy by courses of immunotherapy.
Erbisol is used in the treatment of stomach and duodenum ulcers, erosive ulcerous damages of gastrointestinal tract, traumata, pyo-ceptic wounds and fractures, trophic ulcers and paradontosis10.
However the mechanism of Erbisol action allows to extend sufficiently the sphere of its usage. It is planning to start the clinical trials regarding the therapy of bronchial asthma, cardiovascular diseases, rehabilitation of postmyocardial infarction state, radiation injury and also in gerontology, sexual pathology and in the other directions, a list of which is continually added.

Erbisol preparations are characterized by the original mechanism of action. This mechanism allows these preparations to affect not so much a disease as the body, activating body's control systems responsible for the search and elimination of pathological changes. The immune system is one of such control systems. The preparations targetly activate the immune system which effectiveness manifests itself through macrophages which promote the repair of damaged cells and reparation of functional activity of organs and tissues as well as through N- and T-killers responsible for the elimination of abnormal cells and tissues. Erbisol preparations contain non-proteines complex of the natural organic compounds of non-hormonal origin. They are extracted from the animal embryonic tissues. The preparations contain the specific "signal" low-weight molecules extracted from "markers of cell physiological state". The latter activate natural, evolutionally formed mechanisms of the search and elimination of pathological changes in organs and tissues and promote the body to implement its genetic potential. The rights to develop and produce Erbisol preparations are reserved in 20 countries of the world.
