Abstract
Ethylthiosulfanylate (ETS) is synthetic organosulfur compound and belongs to the class of thiosulfonates, which are the structural analogues of natural BACs of plant origin. Thiosulfonates and ETS in particular affect the regulation of pro/antioxidant status, lipid and protein metabolism in the tissues of laboratory rats. Cr(VI) compounds are characterized by potent prooxidant properties and high toxicity for cells of living organisms. The toxic effect of Cr(VI)-induced oxidative stress is accompanied by lipid metabolism disorders and the correction methods have not been sufficiently studied. The aim of our study was to investigate the effect of ETS on some indicators of lipid metabolism in blood plasma of rats under the action of K2Cr2O7-induced toxicity. Animals were divided into 7 groups. Animals of group I injected daily intraperitoneally with 150 μl of physiological solution for 7 days. Experimental groups III and IV were administered daily intraperitoneally with K2Cr2O7 in a dose of 2.5 mg Cr(VI)/kg body weight, for 7 (group III) and 14 days (group IV). Rats of group II received intragastric injection of 1000 μl of oil daily for 14 days, than animals were injected daily intraperitoneally with 150 μl of physiological solution for 7 days. Experimental group V was intragastrically injected with ETS oily solution at a rate of 100 mg/kg of body weight daily for 14 days, than animals were injected intraperitoneally 150 μl of physiological solution daily for 7 days. Animals of groups VI and VII were intragastrically administered with ETS oily solution at a rate of 100 mg/kg of body weight daily for 14 days, than animals were injected intraperitoneally daily K2Cr2O7 in a dose of 2.5 mg Cr(VI)/kg body weight, for 7 (group VI) and 14 days (group VII). Rats were decapitated under thiopental anesthesia, after which blood was taken and divided into erythrocytes and plasma. The Cr(VI) action for 7 (group III) and 14 days (group IV) led to an increase in the content of total lipids and triglycerides in the blood plasma of rats, but the percentage of nonesterified cholesterol decreased. ETS partially compensates the Cr(VI)-induced toxicity by reducing the intensity of total lipids (groups VI, VII) and triglycerides (group VI) accumulation.
