[Effects of introduction of short peptides before carotid artery occlusion on behaviour and caspase-3 activity in the brain of old rats].

The comparative research of effect of Pinealon and Cortexin on behavior and activity of caspase-3 in a brain of old rats in a model of carotid arteries occlusion was conducted. It is shown that introduction of short peptides promotes a survival rate of the animals that have modeled occlusion of carotid arteries. Under Pinealon before occlusion of carotid arteries, behavioral dream has been increased and a position-finding behavior, a motivational behavior and a motor performance have been reduced.
