title: [Effect of intragastrically injection of phytoecdysteroids on some indicators of hormonal status in rats].
abstract: The experiment in vivo in growing male Wistar rats was carried out. The animals of the experimental 2-4 groups were daily intragastrically injected water solutions of the dried extract from the leaves of Seratulla coronata L. in volume of 1.0 ml, containing 2, 20 and 50 mg of phytoecdysteroids per kg of animal weight, accordingly. Animals of control group were daily injected 1.0 ml of water. The content of phytoecdysteroids in the dry extract was analyzed by high performance liquid chromatography (HPLC). The concentration of the sum of phytoecdysteroids in dry extract was 6.15%, 66% of which was 20-hydroxyecdysone and 23% was 25S-inokosteron. On the 15th day animals were taken out of the experiment by the decapitation. The content of corticosterone, prostaglandin E2 and beta-endorphin in rat blood plasma were determined by ELISA test. The pathological--anatomical analysis and weighing of the liver did not reveal any adverse changes of this organ in the animals of all groups. The average concentration of blood plasma corticosterone reduced with increasing of the dose of the extract injected to the animals, reaching significant differences relative to the control group (60.9 +/- 9.4 ng/ml) for 3 and 4 groups (22.7 +/- 6.6 and 17.6 +/- 7.3 ng/ml, accordingly). Beta-endorphin and prostaglandin E2 levels did not differ. The ratio of the mediator of stress (corticosterone) and inhibitors of stress (beta-endorphin and prostaglandin E2) has been calculated. A monotonic decrease of corticosterone/beta-endorphin and corticosterone/prostaglandin E2 ratio has been found with extract dose increasing. Taken together the results of determination of biochemical parameters of the general adaptation syndrome the dose-dependent stress-protective effect of Seratulla coronata L extract has been demonstrated.
