Abstract
The aim of the study was a morphological assessment of the neuroprotective effect of the combined use of polyunsaturated fatty acids concentrate from fat of the Baikal seal and “Cortexin” in cerebral ischemia rats.
Materials and research methods. The objects of the study were the concentrate of polyunsaturated fatty acids from the fat of the Baikal seal (PUFA) and “Cortexin”. The studies were carried out on Wistar rats of both sexes. Cerebral ischemia was reproduced by unilateral occlusion of the common carotid artery. The effect of the test agents on spatial memory in rats was determined using the “Morris water maze”, and general morphological studies of the brain were performed.
Results. It was found that the course introduction of PUFA together with “Cortexin” to rats subjected to cerebral ischemia had a nootropic effect: in the Morris water maze, the number of exits to the platform was 2 times more, and the average search time for the hidden platform was 1.8 times less compared with control (p≤0.05). By morphological methods, it was found that the severity of ischemic brain damage was noticeably less compared to the indicators of control and experimental rats receiving monotherapy (PUFA or “Cortexin”).
Conclusion. The combined use of “Cortexin” with a PUFA concentrate from Baikal seal fat has a pronounced neuroprotective effect in cerebral ischemia in rats and improves cognitive functions due to the complex action of polypeptide compounds and fatty acids of both drugs.
