Liver and brain mitochondrial ATPase activities in rats exposed to high ambient temperature.
Liver and brain mitochondrial ATPase activities in rats exposed to high ambient temperature. Acta physiol. pol., 1985, 36 (3): 185-192. Rat liver and brain mitochondrial ATPase activities were investigated after a single exposure (6 h) of the animals to temperatures of 21 degrees, 28 degrees and 37 degrees C. An increase of ATPase activity stimulated by Ca++ ions was noted in the mitochondrial fractions of the liver at 28 degrees C and of the brain at 28 degrees and 37 degrees C. Only in liver mitochondria of rats exposed to 28 degrees C a depression of Mg++-ATPase activity was found.
