[Reamberin optimizes drug therapy in children with acute Epstein-Barr viral infection].

The efficacy of a 1.5% reamberin solution possessing detoxicating, antihypoxant, antioxidant, and membrane-protective properties, used as a component of the complex infusion therapy in children with acute Epstein-Barr virus infection, has been estimated. The dynamics of the inflammatory process in children treated by the drug complex including reamberin is characterized by rapid relief of general symptoms, improvement of state, and reduction in length of the febrile period of disease as compared to patients treated with glucose-saline solutions and basic therapy. The administration of reamberin in children contributed to the early elimination of metabolic shifts by the period of convalescence, as evidenced by improvement in some laboratory parameters, including protein-synthesis function of the liver.

[Cycloferon in therapy of hyperplastic laryngitis for decrease of the number of relapses].

The article describes the clinical forms of chronic hyperplastic laryngitis, characterized by persistent and recurrent course, a tendency to the formation of oncological pathology, at the expense of hyperplastic changes in the larynx, leading to a malignancy of the inflammatory process. It was demonstrated the bacterization of larynx by Epstein-Barr virus (EBV) and Mycoplasma in imbalance of system of interferon. Clinical recovery, depending on the clinical form of the disease, using cycloferon, was observed in 57.4% of patients. The inclusion in the complex of the medical support of chronic hyperplastic laryngitis inducer of interferon - cycloferon, provided the reduction of the number of relapses.

[The study of dynamics of clinical and molecular phenotypes in the generalized form of myasthenia with optimized and combined treatment].

The aim of the study was the research of clinical and molecular phenotypes in the generalized form of myasthenia with optimized treantment, which includes the application of basic mode of the treatment and meglumine sodium succinate, and also the combined mode of the treatment, which includes the mode of the treatment and meglumine sodium succinate and ozonotherapy. The most epressed improvement of indicators of the clinical and neurologic status (the eliminaton of motoring breakdown, eye movement disrders, the weaknesses of mimic, respiratory and chewing muscles, bulbar syndrome, the doubling in eye and ptosis, pharyngeal violations and increase in volume of movement of eyes) was observed in the group of patients receiving the combined therapy. The reduction of the epressiveness of the defeat of the neuromotor device and the decrement of the amplitude of the various degree of M-answer in patients with myasthenla is revealed in the application of the combined therapy in the comparison with the application of the basic and optimized therapy. For the first time we have investigaed the dynamics of the intensity of the expression of specfic peptides and proteins in blood serum in patients with the application of basic therapy, reamberin and ozonotherapy, which have allowed to open the new mechanisms of the efficiency ofthe combined therapy of the disease.

[Experience of using reamberin for detoxification therapy at the stage of deworming in children with chronic opisthorchiasis].

The study presents data on the reversible aggregation of erythrocytes in 50 children with chronic opisthorchiasis and 45 children with inflammatory diseases of the upper digestive tract without opisthorchiasis (chronic gastroduodenitis, duodenal ulcers), all patients aged from 7 to 17 years. The results of using reamberin for detoxification therapy at the stage of deworming in children with chronic opisthorchiasis are assessed.

[Evaluation of the effectiveness of immunomodulating therapy in children with chronic gastroduodenitis].

The article assesses the effectiveness of administering immunomodulating drug cycloferon in patients aged 10 to 16 years with chronic gastroduodenitis. It is established that the use of cycloferon in children with virus-associated chronic gastroduodenitis leads to a significant increase in T- and B-lymphocyte populations in mucous membranes of the stomach and duodenum, and contributes to the elimination of viruses. This results in reduced severity and activity of inflammation in the mucous membranes and decreases clinical manifestations of the disease.

[Cycloferon in complex therapy management of chronic laryngitis].

The clinical course of various forms of chronic laryngitis, including contact granulomas not only persistant and relapsing, but also inclined to oncologic pathology due to hyperplastic changes in the larynx resulting in malignization was described. Inhibition of the leukocyte interferon-synthesizing activity was observed in more than 88.1% of the subjects. Pathogenic viruses were isolated from 48.2% of the patients, EBV and mycoplasma prevailing. High direct correlation between chronic laryngitis and Herpes viruses was shown. The presence of three-component virus associations in the larynx mucosa was likely indicative of the bening process malignancy. The use of the interferon inductor cycloferon in the complex surgical and medicamentous management of chronic laryngitis was shown valid. The rate of the relapses lowered to 1.7 episodes a year.

[Virus infections and interferon inducers in the complex therapy].

Interferon inductors of various chemical groups, belonging to antivirals, and induction of several types of endogenous interferon in blood serum are described. Cycloferon was shown efficient in the complex treatment of chronic hepatitis C, tuberculosis in HIV-infected subjects, arbovirus diseases, influenza and acute respiratory virus infections.

[Cycloferon as an agent for the anti-relapse therapy in patients with chronic hyperplastic sinusitis].

The data on the efficacy of cycloferon as an agents of antirelapsing therapy in management of 123 patients with chronic hyperplastic sinusitis are presented. The drug induction of endogenous interferons was validated by the properties of the local mucosal immunity, virus invasion and virus persistence in the nasal an d accessory nasal sinuses mucosa, as well as by different levels ofthe interferon production deficiency. The clinical efficacy was stated in 53% of the cases. The relapses were recorded in 13.1% of the patients treated with cycloferon vs. 33.3% of the patients under the local corticosteroid therapy.

[An experimental study of the efficiency of cycloferon in the complex chemotherapy of generalized drug-resistant tuberculosis].

The results of an experimental study of the efficiency of cycloferon included in a complex chemotherapy of generalized drug-resistant mycobacterium tuberculosis (MBT) are presented. It is established that cycloferon (3.6 mg/kg) produces a significant therapeutic effect, which is manifested by an increase in the lung clearance from MBT, a decrease in the spread of specific inflammation in the lungs, and the disappearance of MBT-induced alterations. In addition, activation of the signs of tension in the local immunity of lung tissues is observed as manifested by changes in the cellular composition of granulomas and more frequent detection of large lymphocytic and macrophage infiltration. The administration of cycloferon significantly increases the absorptive and digestive activity of phagocytosis by peritoneal macrophages, which has been inhibited during the development of experimental MBT infection.

[Comparative evaluation of reamberin and mafusol on acute toxic liver damage models].

Comparative evaluation of the infusion of reamberin and mafusol has been carried out on the model of toxic liver damage caused by ammonium chloride. Reamberin contributed to more rapid normalization of indices due to an increase in the substrate reserve for energy metabolism. In a group of animals with alcohol intoxication, only the treatment with Reamberin allowed the system of antioxidant protection (reduced glutathione, thiol groups) and functional activity of the liver to be to normalized by the end of experiments on a level of the control group (intact animals).

[Intrahepatic induction of endogenous S-adenosyl-L-methionine against the background of various ways of administration of methionine-succinate complex and its role in drug-induced liver lesion correction].

A comparative study of the level of endogenous S-adenosyl-L-methionine (SAM) with other hepatoprotectors in pharmacological correction of liver drug lesion. Among 117male rats. It has been shown that among antituberculous drugs only Remaxol and Runihol were causing significant increase in endogenic S4M. Taking into account the amelioration of lab results as well as histological condition of the liver against the background of Remaxol treatment as well as positive effect of Runihol treatment upon cholestasis, one can draw a conclusion upon the importance of succinic acid together with SAM induction as a part of hepatoprotective effect of the drug. Reamberin, which contains succinic acid without methionine also shows hepatoprotective qualities and doesn't induce endogenous SAM production. Positive therapeutic effect of exogenous SAM regardless the way of administration doesn't correlate with endogenous SAM induction, and is associated with the external hepatocyte cell membrane restoration.

[Supportive therapy for locally advanced cancer of the oral mucosa].

The article discusses the practice of detoxication therapy to minimize undesirable toxic effects during chemo- and radiotherapy for locally advanced cancer of the oral mucosa in 88 patients treated with 1.5% solution of reamberine. There was a significant improvement in the parameters of liver function, as well as in the general wellbeing of patients. We analyzed the main symptoms of the toxicity of chemo- and radiotherapy in both groups. Inclusion of the reamberine solution as supportive therapy for cancer patients who were receiving chemo- and radiotherapy for cancer of the oral mucosa allowed reducing the number and severity of toxic complications.

[Manifestations of immune deficiency in children with perinatal HIV infection in the treatment dynamics].

Clinical and immunological parameters in the children with perinatal HIV infection were investigated in the dynamics of the long-term prospective observation. It was revealed, that all the HIV infected children had clinical signs of immunodeficiency and laboratory signs of combined damage of the immune system. The complex of therapeutic measures, including antiretroviral therapy, prevention of opportunistic and acute respiratory infections, rational immunotherapy to stimulate production of endogenous interferon and normalization of the balance of cytokines significantly reduced the frequency of the clinical manifestations of the infectious syndrome and improved the patients resistance to infections.

[Comparative study of hepatoprotective action of remaxol, reamberin and ademethionine in liver injury induced by antituberculosis drugs (experimental study)].

The hepatoprotective activity of remaxol, reamberin and ademethionine was studied on a model of the liver injury induced by antituberculosis drugs. The study included 30 male uninbred albino rats. The following antituberculosis drugs were used: isoniazid (50 mg/kg) subcutaneously + rifampicin (250 mg/kg) intragastrically + pyrazinamide (45 mg/kg) intragastically (by the procedure of Yu. I. Slivka, 1989). Remaxol, reamberin and ademethionine were administered 1.5 hour prior to the antituberculosis drugs. The treatment course was 14 days. It was shown that remaxol, reamberin and ademethionin were able to correct the structural and functional disorders in the liver due to the use of the antituberculosis drugs. By the impact on the biochemical indices, evident of the liver function condition, remaxol showed the maximum effect. The effect of ream-berin was somewhat lower and the results of the ademethionine use were less significant. Remaxol had also a distinct effect as for lowering the level of the structural injuries in the liver, evident from recovery of the organ histoarchitectonics, less extended carbohydrate, albuminous and fatty degeneration, more active intracellular regeneration. It was noted that ademethionine had an insignificant effect on necrobiosis. Moreover, there was once detected a large necrosis focus, evident of possible stimulation of the liver tissue alteration by the drug.

[Comparative study of remaxol and ademethionine effects on reparative regeneration processes in the liver subjected to surgical intervention].

The influence of remaxol, reamberin and ademethionine on the process of reparative regeneration in the liver was experimentally studied in a group of 100 white male rats subjected to partial hepatectomy in comparison with intact and drug-untreated operated control animals. The administration of remaxol and ademethionine favored more intensive and early accumulation of the regenerated liver weight, restoration of the general structure of the liver, and appearance of the signs of reparative regeneration. Only rats treated with ademethionine exhibited clearly pronounced enhanced alterative processes in the liver. A morphometric investigation showed that remaxol and ademethionine improved the quality of a current compensatory process and stimulated intracellular regeneration reactions. Under the conditions of remaxol administration, the most pronounced effect of liver regeneration was observed on the 4th day after operation, while in the case of ademethionine the maximum effect was observed on the 10th day.

[Induction of endogenous s-adenosyl-l-methionine in hepatocytes during pharmacological correction of experimental acute toxic and chronic drug-induced liver injury].

The level of endogenous S-adenosyl-L-methionine (SAM) production during pharmacological correction of acute toxic (tetrachloromethane) and chronic drug-induced liver injury treated by remaxol, exogenous ademethionine, and reamberin has been studied on 118 outbred male rats. It is established that, upon a single introduction of tetrachlormethane (acute toxic injury model), remaxol and exogenous SAM produced a gain in the endogenous SAM level in hepatocytes. At the same time, in the case of chronic drug-induced injury (antituberculosis drugs), only remaxol caused authentic growth of the endogenous SAM level that was comparable with a compensatory growth of SAM at nontreated animals. Considering the improvement of laboratory indicators and the histological pattern of liver in animals treated by remaxol, it is possible to conclude on the important role of succinic acid along with the induction of SAM, in the hepatoprotective effect of drugs. This is confirmed by the effect of reamberin, which contains only succinic acid without methionine and does not cause induction of endogenous SAM.

[Improvement of treatment of inflammatory diseases in oral cavity].

In order to determine the anti-pathogenic clinical efficacy of cycloferon liniment in the combined treatment of herpetic stomatitis and periodontitis, medical examination and treatment of these disorders have been carried out in a group of 80 patients. It is established that the use of cycloferon liniment in the combined treatment of herpetic stomatitis and periodontitis decreases the infectious load in parodontal recess, reduces the manifestations of local inflammation, normalizes the immunity indices, and decreases the level of endogenous intoxication, which ensures the acceleration of recuperation processes and lowers the frequency of recurrences.

[Gonadotoxic effects of polychlorinated biphenyls in experiments on male rats].

The influence of Sovol, a commercial mixture of polychlorinated biphenyls (PCBs) on the reproductive system was studied on male rats. The results of the experiments showed that PCBs significantly decreased the body and testis weight, the number of the sperm cells in ejaculate and testicular tissue, blood levels of testosterone and estradiole. Increasing of peroxidation was also observed. The results suggested that the revealed disorders may play an important role in pathogenesis of male infertility caused by persistent organic pollutants.
