[Trace effects of short-term temperature action in monoamine oxidase activity]

The influence of short-term hypothermia and hyperthermia on the activity and catalytic properties of rat brain MAO was studied. It was found that short-term action of low and high environmental temperatures had considerable trace effects which differed in direction and duration. MAO activity increased after hypothermia and was maintained at a high level during 4 days. The lowering of serotonin deamination after hyperthermia was observed for 7 days.
