AIM: To study the effects of hypothermia on the contents of AVP,Ang Ⅱ,L-EK,cAMP,Mg 2+ and Ca 2+ in rat plasma and different brain regions.METHODS: The model of experimental hypothermia rat was established and treated in groups randomly.At the end of the experiment,samples of plasma and braintissues were taken and the contents of L-EK,cAMP,AVP,Ang Ⅱ were determined by RIA methods,Mg 2+ and Ca 2+ by atom absorption methods.RESULTS: The contents of Ang Ⅱ,AVP increased significantly in the plasma of Ⅰ,Ⅲ group( P
