title: [Seasonal features of the effect of low temperature on cerebral monoamine oxidase activity and sensitivity of the rat to hyperoxia].
abstract: During winter-spring period, animals staying for three days at 2 degrees C develop changes in the substrate specificity of the rat brain mitochondria type A monoamine oxidase. Activity of the blood serum glucose-6-phosphate dehydrogenase, total peroxidase activity and extraerythrocyte hemoglobin level increase as a result of erythrocyte membrane damage. Rat hyperbaric oxygen sensitivity during this period increases. In autumn, 3-day cold exposure causes no changes in the above biochemical indices or hyperbaric oxygen sensitivity.
