Objective:To observe the changes of the activity of protein kinase A(PKA) and C(PKC)
and further investigate the mechanisms of anti-hypothermia action of Guizhi Tang.Methods:The hypothermia rats induced by i.p.aminopyrine were used to observe the action of Guizhi Tang on the body temperature and to detect the PKA and PKC activity in hypothalamus in model and Guizhi Tang-treated groups using isotopic tracing assay.Results:The drop of body temperature in rats induced by aminopyrine was counteracted and the PKA and PKC activities increased significantly after oral administration of Guizhi Tang.Conclusions:Both PKA and PKC may participate in the mechanism of hypothermia induction and the increases of PKA and PKC may contribute to the anti-hypothermia action of Guizhi Tang.
