The aim of this study was to study the eff ects of using the infusion drug Remaxol in young patients with alcoholic liver disease.Materials and methods: the clinical and laboratory data of 80 young patients with alcoholic liver disease were analyzed, divided depending on the treatment regimen into 2 groups: the main (n = 44) who received Remaxol according to the scheme: 400 ml iv, drip, at a rate 40–60 drops per minute daily, course No. 5–10, and control (n = 36) — received basic therapy. In all patients, the dynamics in blood serum was studied: lipid peroxidation indices (malondialdehyde, diene conjugates), antioxidant protection enzymes (catalase, SOD, glutathione peroxidase), markers of cytolysis, cholestasis and lipid metabolism.Results: initially there was a significant increase in lipid peroxidation processes, accompanied by slight stimulation of the antioxidant system of the liver and pronounced signs of cytolysis and cholestasis. The inclusion of Remaxol in treatment regimens leads to a significant decrease in the level of malondialdehyde and diene conjugates, and the restoration of the antioxidant system (increase in catalase, SOD, and glutathione peroxidase). At the same time, a marked decrease in the syndromes of cytolysis and cholestasis was noted, which was accompanied by an improvement in the condition of the patients: cessation of nausea, restoration of appetite and sleep, and improvement of well-being.

Розкрито особливості антиоксидантної системиорганізму щурів за хронічного кадмієвого токсикозу.Встановлено, що хлорид кадмію у токсичній дозісприяє зниженню активності ферментної й нефер-ментної системи антиоксидантного захисту, на щовказує зниження ферментів глутатіонпероксидази,глутатіонредуктази, супероксиддисмутази, катала-зи та відновленого глутатіону у печінці щурів. Ре-зультати досліджень вказують на те, що хронічнийкадмієвий токсикоз призводить до посиленої акти-вації процесів ліпопероксидації. The features of the antioxidant system of rats with chronic cadmium toxicosiare disclosed. It wasresearched that cadmium chloride in toxic doses reduces enzyme activity of antioxidant system, asindicated by the decrease in enzyme glutathione peroxidase, hlutationreduktazy, superoxide dismutase,catalase and restored glutathione in the liver and blood of rats. The results indicate that chroniccadmium toxicosis leads to enhanced activation of lipid peroxidation.

The objective of research was to study the state of prooxidant and antioxidant systems in the tissues of the lungs, kidneys, pancreas and salivary glands at burn disease. The intensity of the free radical processes was evaluated on the basis of the content of malondialdehyde (MDA) and antioxidant system – based on the indexes of its enzymatic chain: superoxide dismutase and catalase in homogenates of the studied organs. It has been found that changes in experimental burn disease depend on the studied organs and the stage of burn disease. The activation of free radical processes observed in all investigated organs (lungs, kidneys, pancreas and salivary glands). Reactive oxygen species induce lipid peroxidation, which is a universal marker of tissue damage. MDA appears in the body during degradation of polyunsaturated fatty acids and it’s a marker of lipid peroxidation and oxidative stress. It was found the increasing of MDA in all organs, especially in the lungs and kidneys at stage of burn shock. Under these conditions it was observed the decrease of superoxide dismutase and catalase in all investigated organs. At burn disease there is development of disbalance between the action of prooxidant and antioxidant systems due to the activation of free radical processes.
