Objective: The purpose of this study is to examine influences by the order, Reduction and Reinforcement in Acupuncture on cerebral hemodynamics [regional cerebral blood flow(rCBF) and mean arterial blood pressure(MABP)] in normal rats. Methods: This experiments was to to investigate eath other changes of rCBF and MABP at Xingjian(LR2)(1st) Shaofu(HT8)(2nd) Reduction, Xingjian(LR2)(1st) Shaofu(HT8)(2nd) Reinforcement, Shaofu(HT8)(1st) Xingjian(LR2)(2st) Reduction and Shaofu(HT8)(1st) Xingjian(LR2)(2st) Reduction in Acupuncture. Results: 1. LR2(1st) HT8(2nd) Reduction in Acupuncture was decreased rCBF and MABP in compared with normal condition. 2. LR2(1st) HT8(2nd) Reinforcement in Acupuncture was significantly decreased rCBF, and was decreased MABP in compared with normal condition. 3. HT8(1st) LR2(2st) Reduction in Acupuncture was decreased rCBF during acupuncture but was recovered rCBF after with-drawing of the neddle. 4. HT8(1st) LR2(2st) Reduction in Acupuncture was decreased MABP during acupuncture and after withdrawing of the neddle. 5. HT8(1st) LR2(2st) Reinforcement in Acupuncture was significantly increased rCBF during acupuncture and 30min after withdrawing of the neddle. 6. HT8(1st) LR2(2st) Reinforcement in Acupuncture was decreased MABP during acupuncture, but was recovered MABP after withdrawing of the neddle. Conclusions: I suggested that LR2 HT8 Reduction in Acupuncture and LR2 HT8 Reinforcement in Acupuncture cause a diverse response of cerebral hemodynas.

Objectives : The purpose of this study is to compare Xingjian(LR2) Shaofu(HT8) with Dadun(LR1) Shaofu(HT8) on Blood Pressure in Hypertensive RAT induced by Two Kidney One Clip(2KIC). Methods : This experiments was to investigate the effects of LR2 HT8(originated from ${\ll}$Classic on Difficulty${\gg}$ Shi Ze Xie Qi Zi), LR1 HT8(originated from ${\ll}$Ling Shu${\gg}$ Sheng Ze Xie Zhi) acupuncture on the blood pressure, cardiomegalic index, and plasma levels of atrial natriuretic peptide in hypertensive rat induced by 2K1C. Results: 1. Blood pressure was decreased significantly after third acupuncture of LR2 HT8. 2. Blood pressure was decreased significantly after acupuncture of LR2 HT8, but was increased after LR2 HT8. 3. Cardiomegalic index was not changed after acupuncture of LR2-HT8 and LR1-HT8 4. Plasma levels of atrial natriuretic peptide was increased significantly after acupuncture of LR2 HT8 but LR1 HT8 was not changed.

Objectives: The present study investigated the effects of acupuncture treatment and their mechanism by using the kainic acid (KA)-induced epilepsy mouse model. Materials and Methods: The seizure was induced by an intraperitoneal (i.p.) injection of 30 mg/kg KA, and the acupuncture treatment was subsequently administered to acupoint Shaofu(HT8) bilaterally with two pretreatment sessions before injection (total 3 times over 3 days). Twenty four hours after injection, we observed the survival of neuronal cells in the CA3 region of the hippocampus. In addition, the activation of microglia and astrocytes was observed by using CD11b and GFAP immunohistochemistry in the same region. Results: The results indicate that acupuncture treatment reduced the rate of neural cell death in the CA3 region of the hippocampus and decreased the activations of microglia and astrocytes in this region. Conclusion: These results demonstrate that acupuncture treatment protects hippocampal neuronal cell death from KA-induced epileptic seizure by inhibiting the activations of microglia and astrocytes.

Objective: The aim of this study was to investigate anti-ischemic effect of LR1 HT8 Reduction in Acupuncture Methods: I designed to investigate whether LR1 HT8 Reduction in Acupuncture affects cerebral hemodynamics [regional cerebral blood flow(rCBF), pial arterial diameter(PAD), mean arterial blood pressure(MABP)] in normal rats and to make manifest whether LR1 HT8 Reduction in Acupuncture is mediated by cyclooxygenase or guanylate cyclase. The changes of rCBF and MABP were determinated by laser-doppler flowmetry(LDF), and the change of PAD was de terminated by video microscope and width analyzer. Results: The results were as follows; 1. LR1 Reduction in Acupuncture was increased rCBF and PAD, but decreased MABP. 2. HT8 Reduction in Acupuncture was significantly increased rCBF, but decreased MABP, and increased PAD. 3. LR1 HT8 Reduction in Acupuncture was significantly increased rCBF, PAD, but decreased MABP after withdrawing of the needle. This results suggest that LR1 HT8 Reduction in Acupuncture increased significantly rCBF by dilating PAD. 4. Pretreatment with indomethacin(1mg/kg, i,v.) was significantly inhibited LR1 HT8 Reduction in Acupuncture induced increase of rCBF and PAD, but increased LR1 HT8 Reduction in Acupuncture induced decrease of MABP after withdrawing of the needle. 5. Pretreatment with methylene blue($10{\mu}g/kg$, i,v.) was decreased LR1 HT8 Reduction in Acupuncture induced increase of rCBF and PAD, but accelerated LR1 HT8 Reduction in Acupuncture induced decrease of MABP. Conclusions: I suggest that LR1 HT8 Reduction in Acupuncture has an anti-ischemic effect through the improvement of cerebral hemodynamics, and the mechanism is mediated by cyclooxygenase.

Objectives : To confirm whether acupuncture can suppress the degree of seizure and the activation of astrocytes in hippocampi using kainic acid(KA)-induced epilepsy mouse model. Methods : 8 weeks C57BL/6 mice(20~25 g) were given acupuncture once a day at acupoint HT8(Shaofu) bilaterally during 2 days before KA injection. After an intraperitoneal injection of 30 mg/kg KA, acupuncture treatment was subsequently administered once more(total 3 times), and the degree of seizure was observed for 120 min. The neuronal cell death, pERK expression, and astrocyte activation confirmed 1 hour and 24 hours after KA injection. Results : Acupuncture treatment at HT8 suppressed KA-induced epileptic seizure. One hour after KA injection, the pERK expression was increased, which was reduced by the acupuncture treatment. Twenty four hours after injection, the treatment decreased the KA-induced neuronal cell death, the interleukin-$1{\beta}$ expression and the astrocyte activation in the CA3 region of the mouse hippocampus. Conclusions : Acupuncture treatment at HT8 decreases the KA-induced epileptic seizure, the neural cell inflammation and death.

Objectives : In this research, it was investigate that had effects on acupuncture techniques of $HT_{8}$(Shaofu) and $LR_{2}$(Xingjian) acupoints in high fat rats. We recorded data of weight gain, food intake, food efficiency, total cholesterol, triglyceride, AST, ALT, r-GTP, total bilirubin on rats fed high fat diet for 10 weeks. Methods : We divided experimental groups into four. Group of high-fat diet feeding and no treatment was control, group of high-fat diet feeding and acupuncture at $HT_{8}{\cdot}LR_{2}$ was Acu-1, group of high-fat diet feeding and acupuncture at $HT_{8}{\cdot}LR_{2}$ and rotated counter-clockwise 36times was Acu-2, high-fat diet feeding and acupuncture at $HT_{8}$(body direction)${\cdot}LR_{2}$(lower limb direction) and rotated counter-clockwise 36times was Acu-3. Results : In Acu-3 group, body weight on 2 weeks after starting acupuncture, food efficiency and the level of serum total cholesterol were decreased, and the level of HDL-cholesterol was increased. In Acu-1 group, the level of triglyceride was increased but ALT was decreased. Conclusions : These results suggest that treatment of acupuncture at $HT_{8}$(body direction)${\cdot}LR_{2}$(lower limb direction) and rotated counter-clockwise 36times may be having the influence on high fat by controlling the level of serum total cholesterol and HDL-cholesterol.
