초록

1. Purpose For many years, Taeumin Chungsimyoinjatang(太陰人 淸心蓮子湯, CS) has been used in Sasang(四象) constitutional medicine as a therapeutic agent for cerebral disease. The effects of CS on the vascular system is not well-known. The purpose of this study is to make it clear the effects of SJ and composing drugs on blood pressure(BP) and regional cerebral blood flow(rCBF). 2. Method We measured BP with Pressure Transducer, rCBF with Laser-Doppler flowmeter. Propranolol and methylene blue were used to determine the mechanisms of CS effects. 3. Results and Conclusion BP was not affected by CS in rats, and rCBF was significantly increased by CS in rats. rCBF was increased by Nelumbinis Semen(蓮于肉), Ophiopogonis Radix(麥門冬), Asparagi Radix(天門冬), Polygalae Radix(遠志), Zizyphi Spinosae Semen(酸棗仁), Longnae Arillus(龍眼肉), Raphani Semen, Chrysanthemi Flos(甘菊) in rats. The increase of rCBF is mediated by adrenergic β- receptor and guanylyl cyclase which is enzyme producing cyclic GMP. 1. 연구목적太陰人 淸心蓮子湯은 『東醫壽世保元』 태음인병 24처방 중에 기재된 신정방으로 태음인 肝燥熱證에 응용되는 처방이다. 근래에는 뇌졸중을 비롯한 중추신경계통 질환에 많이 사용되고 있다. 이러한 太陰人 淸心蓮子湯의 용도를 과학기기를 이용하여 기전을 규명하고자 하였다. 2. 연구방법백서를 urethane으로 마취시키고 太陰人 淸心蓮子湯을 투여한 후 Pressure Transducer와 Laser-Doppler flowmetry를 이용하여 백서의 혈압과 국소뇌혈류량을 측정하였으며 이를 구성약물까지 진행하였다. 또한 太陰人 淸心蓮子湯의 대뇌혈류에 관한 기전 규명을 위하여 propranolol과 methylene blue로 전처치한 후 太陰人 淸心蓮子湯을 투여하여 이를 분석하였다. 3. 결과 및 결론太陰人 淸心蓮子湯의 투여로 혈압의 유의한 변화는 없었으며, 국소뇌혈류량은 유의하게 증가되었다. 구성약물 중 蓮子肉, 麥門冬, 天門冬, 遠志, 酸棗仁, 龍眼肉, 蘿菔子, 甘菊은 국소뇌혈류량을 유의하게 증가시켰다. 이 실험으로 太陰人 淸心蓮子湯의 국소뇌혈류량 증가의 기전은 교감신경 β-수용체와 cyclic GMP의 생성효소인 guanylyl cyclase의 작용과 관련이 있는 것으로 생각된다.
