Aim: to assess lipid profile, lipid peroxidation and antioxidant system parameters in peri - and postmenopausal women with obstructive sleep apnea syndrome (OSAS). Materials and methods. 37 perimenopausal women and 43 postmenopausal ones were examined. OSAS diagnosis was made on the basis of the clinical picture and the polysomnography results. In perimenopause, the main group consisted of 18 women, in postmenopausal women - 17. All comparison groups are comparable by age and body mass index. Lipid profile, lipid peroxidation and antioxidant system parameters by spectrophotometric methods were determined. Non - parametric criteria were used to analyze the group differences for the independent samples. Results and discussion. The increase of total cholesterol (TC) and low - density lipoprotein cholesterol (LDL-C) levels were observed in perimenopausal women with OSAS as compared to control. The increase of TC, triacylglycerol (TG), LDL-C, very - low - density lipoprotein cholesterol (VLDL-C) levels and decrease of high - density lipoprotein cholesterol (HDL-D) level were found in postmenopausal women with OSAS as compared to control. Accumulation of ketodienes and conjugated trienes in perimenopausal women with OSAS and thiobarbituric acid reactants with a decrease of total antioxidant activity of blood serum in postmenopausal women with OSAS as compared to control was observed. Moreover, postmenopausal women with OSAS have a higher lipid peroxidation substrates and diene conjugates levels with a lower α-tocopherol level and total antioxidant activity compared with perimenopausal patients.The integral indicator of oxidative stress assessment indicates an imbalance in the lipid peroxidation and antioxidant system in menopausal women with OSAS. Conclusion. The results obtained indicate a violation of lipid metabolism and the development of oxidative stress in patients with OSAS. This is most pronounced in the postmenopause due to the aggravation of the pathological condition.

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.
