EFFECT OF CHRONIC ADMINISTRATION OF LOW DOSES OF POLYPEPTIDES OF CATTLE CEREBRAL CORTEX AND...

In the modern world, anyone is susceptible to the effects of stress, regardless of age, gender, culture, and social status. Stress at an early age accelerates long-term changes in the functional properties underlying emotional perception and therefore may alter the stress response later in life. Unfortunately, the interdisciplinary approach in stress research emphasised the study of stress phenomenon in the development of this or that pathology or manifestation of appropriate reactions under the influence of this or that factor, i.e. the study of a particular case, which did not significantly affect the conceptual level of interpretation of the stress phenomenon as such. Moreover, we did not come across any publications interpreting the pathogenesis of the development of the classical triad of stress, confirming, or refuting its validity. In this study, we evaluated the effect of nootropic drugs - polypeptides of cattle cerebral cortex and methionyl-glutamyl-histidyl-phenylalanyl-prolyl-glycyl-proline on the behaviour of rat offspring under conditions of maternal deprivation. The drug affects processes related to memory formation and learning, enhances attention during learning and analysis of information, improves adaptation of the organism to hypoxia, cerebral ischaemia, anaesthesia and other damaging effects. As a result of the conducted study against the background of early postnatal maternal deprivation and the use of such drugs as methionyl-glutamyl-histidyl-phenylalanyl-prolyl-glycyl-proline and polypeptides of cattle cerebral it was noted that the latter drug showed the greatest effectiveness as a means of compensating the reaction to chronic stress under conditions of maternal deprivation.
