[Aminotransferase activity in the brain tissue in hypothermia and self-heating]

A single as well as repeated (3 days later) hypothermia of 20 degrees C is accompanied by a significant rise in the transaminase activity in great hemispheres, cerebellum, midbrain and diencephalon. An increase in the enzymes activity is especially pronounced at the incubation temperature corresponding to the body temperature of a hypothermal animal. Organism self-heating causes a decrease in the activity of aspartate- and alanine aminotransferases. Three days after rats self-heating these enzymes manifest a lower activity as compared to that in the normothermal control animals.
