[CARDIOVASCULAR SYSTEM REACTIVITY IN PRENATALLY STRESSED RATS DURING THE LATE PERIOD OF ONTOGENESIS].

Systolic, diastolic blood pressure and heart rate were determined in normal rats and those exposed to influence of chronic stress during gestation. Data were registered six months after the birth and in 5, 24 and 48 hours after their immobilization. Analysis of the data showed that in rats undergoing stress, recorded systolic, diastolic blood pressure and heart rate both before and during all periods of immobilization were significantly below than in control group. It is concluded that the maximum limit of motor activity in the prenatally stressed rats accompanied by a decrease in the values ​​recorded performance of the cardiovascular system, which is reflecting the decrease in these animals reactivity of the cardiovascular system, and thus the adaptive capacity for action of stress factors.
