Effect of immobilization stress on myocardial ultrastructure has been studied in rats occupying, according to the behavior, dominant, subdominant and "outcast" position in the group. The greatest changes are revealed in the myocardium of the dominant rats. This is explained by the fact, that mechanisms ensuring realization of certain functional systems in these animals require maximal energetic and emotional expenditure. And as the result--compensatory ability of their physiological function is lower than in animals of other ranks.
在一组大鼠中，根据行为将其分为占据主导地位、次主导地位和“被排斥”地位的三类，研究了固定应激对心肌超微结构的影响。结果发现，主导地位大鼠的心肌变化最为明显。这是因为在这些动物中，确保特定功能系统实现的机制需要最大的能量和情感消耗。因此，它们生理功能的代偿能力低于其他等级的动物。
