Abstract


The aim of the study was to determine the circadian dynamics of the carbohydrate metabolism and the activity of cytolysis markers in females and male rats. For this purpose the chronopharmacological studies with collecting blood and liver tissues of the experimental rats at the scheduled time (03.00, 09.00, 15.00 and 21.00) have been carried out. As a result of the research conducted the presence of diurnal fluctuations in the glycogen level, the content of corticosterone and glucose in male rats with the lower rhythm expression in females, and the practical absence of the circadian rhythm in the activity of ALT and AST in animals of both sexes have been determined. Significant gender differences between male and female rats have not been revealed. The results of the circadiance organization of the carbohydrate metabolism and the activity of cytolysis markers obtained in rats should be taken into account when analyzing a chronoprofile of hepatoprotectors and other drugs.
