Abstract

CheonghunHwadam-tang(CHT) have been used in oriental medicine for many centuries as a therapeutic agent of vertigo by wind, fire and phlegm. CheonghunHwadam-tangGamypang(CHTG) was CHT adding Aurantii Fructus(AF), Gastrodae Rhizoma(GR). The effects of CHT on the cerebral blood flow and cardiacvascular system is not known. The purpose of this Study was to investigate effects of CHT and CHTG on the regional cerebral blood flow(rCBF), mean arterial blood pressure(BP), cardiac muscle contractile force(CMF), heart rate(HR). The changes of cerebral blood flow and movement of cardiacvascular system(BP, CMF, HR) was determinated by Laser-Doppler Rowmetry(LDF). The results were as follows; 1. CHT extract increased rCBF, but decreased BP, HR in a dose-dependent manner. 2. AF extract accelerated rCBF and movement of cardiacvascular system in a dose-dependent manner. 3. GR extract increased significantly rCBF(10.0mg/kg, p<0.05) as well as accelerated BP and rCBF in a dose-dependent manner. 4. CHTG extract increased significantly rCBF(10.0mg/kg, p<0.01) in a dose-dependent, but was not changed movement of cardiacvascular system. This results suggest that CHTG is significantly treated more than CHT in vertigo by wind, fire and phlegm.
