Comparison of the Adaptive Capacity in Old and Young Wistar Rats to Stress Exposure and Acute Hypoxic Hypoxia. | LitMetric

We compared behavioral and psychoemotional manifestations of young and old male Wistar rats in elevated plus-maze, the levels of corticosterone and testosterone, as well as the resistance to acute hypoxic hypoxia before and after stress exposure (10-min swimming sessions over 10 days). The behavioral characteristics, responses of the main stress hormone corticosterone, and resistance to acute hypoxic hypoxia were identical in both age groups before and after stress. A distinguishing feature was pronounced flattening of the psychoemotional manifestations in old animals. The main adaptive differences between young and old rats were revealed in the response of circulating testosterone to stress.
