[Change in prostaglandin levels and ATPase activity of cardiac membrane fractions during the formation of cerebral hematomas in animals with a hereditary predisposition to stroke].

The formation of subarachnoidal, intragastric, and intracerebral hepatomas provoked by stress in rats hereditarily predisposed to strokes was found to be accompanied by myocardial overstrain and changes in cardiac prostaglandin formations, as well as by a decrease in the activity of ion-transporting enzymes, such as Na, K- and Ca,Mg-ATPases in the plasma membranes, Ca-ATPase in the sarcoplasmic reticulum.
