Objective:To investigate the effect of Guizhi Tang on the time course of cerebral 15 hydroxy prostaglandin dehydrogenase(15-PGDH)in pyretic rats. Methods: The activity of 15-PGDH in hypothalamus and the other cerebral tissues at different time in rats were measured using radio-TLC assay. Results: Paralleled to a fever response induced by a s.c.injection of yeast
the activity of 15-PGDH decreased first
then followed by a gradual return to baselime. Treatment with Guizhi Tang inhibited the decrease of PGDH activity and enhanced it to above normal level;similar changes appeared to the other cerebral tissues while the recover in the later phase was inhibited by Guizhi Tang. Conclusion: Present data suggest that the decrease of the PGDH activity in hypothalamus may contribute to the early stage of fever-induction by yeast in rats and the increase of the enzyme may be one of the antipyretic mechanisms of Guizhi Tang.
