[Effect of prostatilen AC suppositories on course of experimental prostatitis].

The article presents the results of evaluation of efficacy of new drug prostatilen AC (rectal suppositories), containing regulatory peptides of the bovine prostate and zinc arginate-glycinate complex, in the treatment of prostatitis. The experiment was conducted on 40 Sprague-Dawley rats weighing 180-200 g. Chronic prostatitis was modeled by injection of 10% Dimexidum in combination with water, mixed with turpentine, a volumetric ratio of 4:1. It is shown that prostatilen AC has pronounced organotropic antiinflammatory effect, which manifests in reducing the weight of the prostate, reducing the protein level in the urine, activity of acid phosphatase, and levels of ceruloplasmin and C-reactive protein. In addition, this drug normalizes the act of urination and increases the diurnal diuresis, has antioxidant properties and increases the blood level of the male sex hormone testosterone.

[Gastroprotective activity of modified glutamyl-tryptophan dipeptide analogs and melatonin].

The gastroprotective action of synthetic dipeptides glutamyl-tryptophane (EW), iso-valeroyl-glutamyl-tryptophane (ivEW) and nicotinoyl-glutamyl-tryptophane (nEW) in comparison to melatonin was studied in experiments on male with the model indometacine and starvation stress-induced stomach ulcers. It was shown, that EW and melatonin exhibit antiulcer activity upon preventive intragastric administration on the model of starvation stress stomach ulcers. At the same time, ivEW, nEW, EW and melatonin exhibit antiulcer activity during the treatment of model indometacine-induced stomach ulcers. The maximum gastroprotective action was observed for ivEW on the model of indomethacin-induced stomach ulcer. The therapeutic efficiency of substances studied is based on their cytoprotective, antioxidant and immunomodulating action.

[Experimental justification of approaches to pharmacological correction of delayed disorders caused by acute ethylene glycol poisoning].

The development of delayed disorders caused by acute ethylene glycol poisoning has been studied in experiments on male rats. These disorders include chronic renal failure and secondary combined immunodeficiency status of the "circulus vitiosus" type. Urgent pharmacological correction was shown to be necessary shortly after the poisoning. The experimental therapy (administration of immunomodulators with various mechanisms of action in addition to conventional antidote treatment with ethanol) resulted in the restoration of nonspecific resistance and both cellular and humoral immunity. Reduction of the urinary system damage after the administration of immunomodulators was observed. The results demonstrated the importance of multiagent immunotherapy for the correction of delayed effects of acute ethylene glycol poisoning.

[Remaxol in pharmacological correction of long-term disorders caused by acute ethylene glycol poisoning].

The effect of remaxol therapy as a part of the complex acute treatment of ethylene glycol poisoning has been experimentally studied on rats. Special attention was paid to the development of acidosis and hypoxia and a decrease in the functional activity of the urinary and immune systems. It was shown that remaxol is capable of restoring the functional activity of organs and systems susceptible to the toxic effect of ethylene glycol. It is suggested that the therapeutic efficiency of remaxol is based on the normalization of metabolic processes in the cell.

[Antinicrobial, antiexudative and immunotropic properties of chlorhexidine bigluconate in combination with zinc oxide, succinic and ascorbic acids].

Optimal combination of chlorhexidine bigluconate with ascorbic acid, succinic acid, and zinc oxide was found as a result of comparative trials. The composition shows antioxidative effects and is capable of initiating antibody producing and phagocytosis. This combination can be used as an active substance of orodispersible tablets for the treatment respiratory tract infections.

[Oxidative stress and combined antioxidant energy correction in the treatment of periodontitis].

Experimental-clinical study with inclusion of 50 Wistar rats with modeled parodontitis and 71 patients with chronic generalized parodontitis of different severity degree was conducted. Significance of oxidation stress in disease development and running was established in the course of the study. Disbalance of free-radical processes (FRP) in case of periodontal diseases affects oxygen stage of the oxidation stress in bigger degree and continues for a long time. In the course of experiment positive influence of cytoflavine preparation as energy-correction and antioxidant was confirmed as well as its combination with calcium-D3. In the course of comprehensive clinical study the efficacy of cytoflavine use was verified by the example of FRP correction that was accompanied by clinical picture and treatment results improvement.

[Preclinical study of Reamberin and Remaxol safety].

Preclinical safety of reamberin, a preparation of succinic acid intended for the treatment of patients with shock conditions of different etiology, and remaxol a drug intended for the treatment of patients with liver dysfunction caused by acute intoxication was performed. Both medicines belong to the 5th class of practically non-toxic drugs. Their administration to experimental animals for 30 days did not cause toxic effects on the functional and morphological state of main systems and organs. Both medicines do not affect specific (humoral and cellular) and non-specific immune response and do not cause sensibilization, mutagenic, embryotoxic and teratogenic effects, and also do no alter parameters of reproductive functions of rats.

[Detoxicating properties of remaxol with respect to multiple organ failure during severe ethanol poisoning].

Experiments on male rats showed that severe alcohol poisoning results in a multiple organ failure followed by functional impairment of heart, liver and kidney. Intensive infusion therapy with remaxol was found to significantly restore the functional activity and morphological structure of the target organs of ethanol intoxication. The results suggest that remaxol possesses antihypoxic, detoxicating, and hepatic and renal protective properties with respect to severe ethanol intoxication.

[Apoptosis--universal mechanisms of cell death and survival in ischemia and reperfusion: ways to pharmacological control].

Cell death is the main element of ischemic-reperfusive states. The balance of main cell death forms (necrosis and apoptosis) in impaired tissues determines the extent of cellular loss and the rate of pathological process spreading, as well as the possibility of functional recovery. The review describes triggering mechanisms of apoptosis under the ischemia-reperfusion conditions, considers the role of inflammation in limiting the cell loss and its dependence on the balance of necrotic and apoptotic forms of cell death at the site of ischemia-reperfusion, and suggests potential methods for pharmacological correction of protective potency of the cell and the balance of cell death forms.
