Antihypoxic activity and anti-ischemic effect of complex herbal remedy

Abstract

The present study was carried out to determine the antihypoxic and anti-ischemic effects of a polyherbal extract from Astragalus membranaceus, Scutellaria baicalensis and Phlojodicarpus sibiricus. The Wistar rats of both sexes were used in the study. The antihypoxic activity of the extract was studied using hemic and hypobaric models of hypoxia. The anti-ischemic effect of the extract was evaluated by the severity of neurological deficit and survival within 24 hours in model of bilateral occlusion of the common carotid arteries.

The course administration of the extract (100, 200 mg/kg) had an antihypoxic effect in the model of hemic hypoxia: the reserve time of life increased by 26 and 28%, respectively, compared with the control. The course introduction of the extract at doses of 50, 100 and 200 mg/kg increased the reserve time of life in hypobaric hypoxia by 12.3, 15.5 and 16.7%, respectively, compared with the control

The administration of the extract (100 and 200 mg/kg) in the model of cerebral ischemia had a cerebroprotective effect: the indicators of neurological deficit were, respectively, less than the control by 34 and 46%, and their survival was 62 and 64%, respectively, against 20% of the survival of rats in the control group. The results of the conducted studies suggest the prospects for further study of the plant extract as a cerebroprojector agent.
