[Changes in oxidative phosphorylation in rat liver mitochondria during the development of cholestasis]

Kinetic patterns of oxydative phosphorylation were studied in rat liver mitochondria in dynamics of cholestasis and after addition of bile acids to mitochondria in vitro. Within the 1 and 3 days of cholestasis mitochondrial synthesis of ATP was decreased due to inhibition of ATP and ADP transport by the bile acids. At the period within 3 and 15 days uncoupling of the oxidative phosphorylation occurred; the phenomenon observed might be a result of impairment in the structure of inner mitochondrial membrane.
