[Effects of hypothermia on ATPase activity in the cerebral tissue of rats].

The hypothermia 20 degrees C of various periods of action stimulates greatly the activity of Na,K-ATF-ase and causes some insignificant changes in the process of Mg-ATF-ase in homogenates, synaptosomal and mitochondrial fractions, extracted from cortex of big hemispheres. The gained data testifies to some differences of the properties of membrane while cooling.
