title: Functional impairment of mitochondria from rat livers acutely injured by thioacetamide.
abstract: Thioacetamide, when administered in a dose of 100 mg/kg body weight to adult female rats, leads to functional disturbances in mitochondria isolated from livers 24 h after its application. The RCI is significantly reduced due to an increase in state 4 respiration and a lowered state 3 activity. Maximum respiratory activity of the mitochondria is also depressed. The mitochondrial Ca2+-content is significantly increased to 185%. In accordance with the uncoupling effect the Ca2+-transport behaviour of the hepatic mitochondria from thioacetamide-injured rats is altered. The results are indicative of structural alterations of the inner mitochondrial membranes.
