Abstract

Objective : The purpose of this study was to investigate the effects of Sasim-tang water extract on the cardiovascular systems including changes of blood pressure and regional cerebral blood flow volume (rCBF) in male Sprague-Dawely rats. Methods : The changes of blood pressure were recorded by data acquisition system composed of MacLab and Macintosh computer. The changes of rCBF were observed by Laser-Doppler flowmetry through a opened cranial window. Results : 1. The changes of blood pressure was not affected by Sasim-tang extract intravenous injection in rats. 2. After pretreatment with propranolol(3mg/kg), L-NNA(10mg/kg) and 000(10mg/kg), the changes of blood pressure was not affected by Sasim tang extract intravenous injection in rats. 3. The changes of rCBF was increased in dose-dependent manner by Sasim-tang extract intravenous injection in rats. 4, After pretreatment with propranolol(3mg/kg), ODQ(10mg/kg) and L-NNA(10mg/kg), rCBF was significantly decreased in dose- dependent manner by Sasim-tang extract intravenous injection in rats. Conclusions : These results suggest that Sasim-tang was related to the regulation of the sympathetic nerve system, nitric oxide synthesis and synthesis of cyclic GMP.
