Radeva-Domustchieva D, Russanov E: Effect of exhaustive swimming on the oxidative phosphorylation and the activity of some enzymes in rat liver mitochondria. Acta Physiol Pharmacol Bulg. 1976;2(1):72-7. In liver mitochondria of control animals and of animals subjected to swimming for three hours experiments are made to determine the activities of rotenone-insensitive NAD.H-cytochrome c-oxireductase, succinate-cytochrome c-oxireductase, MDH, SDH, ATP-ase and cytochrome oxidase, as well as oxygen uptake, respiratory control index and ADP/O ratio upon oxidation of succinate and glutamate + malate. Decrease of the ADP/O ratio and of the respiratory control index, as well as increased ATP-ase activity, are established after swimming. The e--transport rate decreases. The activity of the remaining enzymes is unchanged. The activities of MDH, SDH, NAD.H-cytochrome c- and succinate-cytochrome c-oxireductases decrease 22 hours after exhaustive swimming. The activities of the cytochrome oxidase and the ATP-ase are unchanged compared with the controls. A single exhaustive loading results in changes in the capacity of phosphorylation in the liver mitochondria and the changes in the activities of the enzymes studied are established 22 hours later. |
