[Glutathione metabolism in rat cardiac tissues in acute doxorubicin-induced intoxication].

Experimental data are presented on the influence of acute doxorubicin intoxication with 7.47 and 2.34 mg/kg body mass on glutathione metabolism in cardiac tissues of albino non-inbred rats. Doxorubicin toxic effect resulted in such marked changes as decreased concentration of reduced glutathione and abnormal levels of glutathione reductase, glucoso-6-phoshate dehydrogenase, glutathione peroxidase and glutathione-S-transferase. Possible causes of such biochemical changes as well as their role in causation of doxorubicin cytotoxic effect are discussed. New methods of prophylaxis and lab diagnosis of doxorubicin-induced cardiomyopathy are suggested.

[The glutathione-dependent antioxidant system in rats during acute intoxication by hydrazine].

Intensity of lipid peroxidation in the liver, kidney and brain tissues, and functioning of the glutathione system were studied in purebred rats after acute intoxication by 1.1-dimethyl hydrazine at the dose of 104.5 mg/kg of body mass (LD50) and phenyl hydrazine at the dose of 170 mg/kg of body mass (LD50). According to results of the investigation, the character and direction of changes in LPO and the antioxidant system due to intoxication by hydrazines are materially dependent on their structure and affected organs and tissues. For instance, intoxication by phenyl hydrazine markedly activates free-radical activation in all analyzed tissue with accumulation of malone dialdehyde against depletion of reduced glutathione in tissue and deactivation of enzymes involved in the antioxidant defense. Intoxication by dimethyl hydrazine was associated with moderate activation of free-radical oxidation in liver with a downward LPO trend in kidney and brain at the cost of exaggerated activity of enzymes in the glutathione system and maintenance of sufficient reserve of reduced glutathione. Hence, aryl hydrazine derivatives possess more distinct pro-oxidant properties.

[Method for measuring glutathione system parameters in human lymphocytes].

The levels of reduced glutathion, activity of glutathion peroxidase, and glutathion S-transferase were measured in human peripheral blood mononuclears. The adapted methods permit measurements of glutathion system parameters in immunocompetent cells and can be used in patients with different immunopathological processes.

[Correction of free radical processes by a succinic acid drug (reamberine) in intensive care of patients with acute neurotropic poisoning].

Sixty-six patients with acute poisonings with neurotropic toxins (soporiphics, neuroleptics, antidepressants, ethanol and its surrogates) were examined and treated. Clinical data and correction of disorders in free-radical processes in acute poisonings with these toxins indicate the efficiency of adding reamberine to combined therapy of this patient population.

[Drug correction of hypoxia aftereffects in patients with toxic coma caused by acute neurotropic poisoning].

Seventy-eight patients with acute neurotropic poisoning (soporifics, neuroleptics, antidepressants, ethanol and its surrogates, narcotics) were examined and treated. Study of the pathogenesis of hypoxic injuries in acute neurotropic poisoning demonstrated the efficiency of using Perfluorane, an infusion solution with oxygen transporting functions, and Cytoflavine, a substrate antihypoxant, for correction of the detected disorders.
