  • Geopungdodam-tang(GDT) have been used in oriental medicine for many centuries as a therapeutic agent of apoplexy. The mechanism of GDT on the cerebral blood flow is not known. The purpose of this Study was to investigate effects of GDT on the pial arterial diameter and action mechanism of GDT-induced increased regional cerebral blood flow(rCBF). The changes of regional cerebral blood f1ow(rCBF) was determinated by Laser-Doppler Flowmetry(LDF), and the changes of pial arterial diametet were determinated by video microscopy methods and video analyzer. The results were as follows ; 1. Pial arterial diameter was significantly increased by GDT in a dose-dependent manner. 2. Pretreatment with L-NNA significantly inhibited GDT induced increased rCBF. 3. Pretreatment with methylene blue significantly inhibited GDT induced increased rCBF. 4. Pretreatment with indomethacin inhibited GDT induced increased rCBF. These results suggest that GDT causes a diverse response of cerebral hemodynamics(rCBF and pial arterial diameter). The cerebral hemodynamics is also mediated by nitric oxide synthase, cyclic GMP(guanylyl cydase) and prostaglandin(cyclooxygenase).

  • For the purpose of developing a new drug against cerebral infarction, we chose Ijintang which is frequently applied in the field of Jung Pung of traditional medicine. From this formula, water extract and methanol extract were prepared respectively. Animals were divided into three groups; control group, water extract medicated group, methanol extract treated group. water extract was given 195mg/kg orally and methanol extract, 165mg/kg for 2 weeks in case of cerebral edema and 1 month in regional cerebral blood flow. On the regional cerebral blood flow, the drug medicated groups showed no significant changes as compared gith control group. There was no significant difference on the cerebral edema among the groups. According to the results above, it is suggested that oral medication of water extract and methanol extract from Ijintang have no effect on the change of rCBF and edema after acutely induced cerebral infarction. However, it is thought that modification of administration method and development of new animal model for traditional medicine are needed.

  • SosokMyeongTang(SMT) have been used in oriental medicine for many centuries as a therapeutic agent for cerebral disease. The effects of SMT on the vascular system is not known. The purpose of this study was to investigate the effects of SMT on the changes in blood pressure(BP) and regional cerebral blood flow(rCBF) of rats. SMT consists of the following components : Radix Ledebouriellae(防風), Radix Cocculi or Stephaniae(防己), Semen Armeniacae(杏仁), Cortex Cinnamomi(肉桂), Radix Scutellariae(黃芩), Radix Paeoniae Lactiflorae(白芍藥), Radix Ginseng(人蔘), Rhizoma Cnidll(川芎), Herba Ephedrae(麻黃), Radix Glycyrrhizae(甘草), Radix Aconiti(附子?), Fructus Zizyphi Jujubae(大棗), Rhizoma Zingiberis(生薑) and the changes of BP and rCBF were tested Leser-Doppler Flowmetry(LDF) The experimental results were as follows ; BP was not affected by SMT in rats, but rCBF was increased significantly by SMT in a dose dependent manner. SMT increased previous decreasd rCBF due to pretreatment methylene blue, but did not increased previous decreasd rCBF due to pretreatment L-NNA, indomethacin. Pretreatment with indomethacin decreased BP compaired with control group. These results suggest that SMT causes a diverse response of blood pressure and regional cerebral blood flow(rCBF). The increased rCBF is mediated by nitric oxide synthease.

  • Experimental Study of Taegye($KI_3$) Taebaek($SP_3$) Draining Acupuncture on the Improvement of Cerebral Blood flow and Arterial Blood Pressure. Objectives : This study was designed to investigate the effects of acupuncture on Taegye($KI_3$) Taebaek($SP_3$) draining and determine the mechanism of action of PCBL by measuring the changes of regional cerebral blood flow (rCBF) and mean arterial blood pressure (MABP) in normal rats. Methods : This study was designed to investigate whether acupuncture on Taegye($KI_3$) Taebaek($SP_3$) draining affect Regional cerebral blood flow(rCBF), Mean arterial blood pressure(MABP) in normal rats. To make manifest whether acupuncture on Taegye($KI_3$) Taebaek($SP_3$) draining was mediated by inhibitor of cyclooxygenase or guanylate cyclase which diate arterial diameter. Results 1. Acupuncture on Taegye($KI_3$) Taebaek($SP_3$) draining significantly increased rCBF but decreased MABP. This result suggests that Acupuncturing on Taegye($KI_3$) Taebaek($SP_3$) draining might significantly increase rCBF by dilating arterial diameter. 2. Acupuncture on Taegye($KI_3$) Taebaek($SP_3$) draining induced increase of rCBF was significantly inhibited by pretreatment with indomethacin (1 mg/kg, i.p.), an inhibitor of cyclooxygenase. 3. This result suggests that the action of Acupuncture on Taegye($KI_3$) Taebaek($SP_3$) draining might be mediated by cyclooxygenase.
