[Features of energy metabolism of myocardial mitochondria and their ultrastructure in normal and immobilized rats of different animal social rank].
The oxidative and phosphorylating functions of mitochondria (M) and their ultrastructure were studied in the myocardium of normal and 6.5-hour immobilized rats that belonged to different zoosocial groups. M from dominant rats under normal conditions were shown to exhibit higher energy and to possess better respiratory energy regulation than those of "outcast" rats. However, the ultrastructure of M had no group specificity in normal. The immobilization caused more profound changes in M from the dominant rats and led to a more pronounced swelling of M in the myocardium of the above rats than in the "outcast". M from the subdominant rats were most resistant to an immobilization stress.
