This Study was designed to investigate the mechanism of Mixture of Bambusae Caulis in Liquamen and Bamboo Extract on the change of regional cerebral blood flow (rCBF) and blood pressure (BP) in normal rats, and further to investigate cytokines production in serum of cerebral ischemic rats. Mixture were as follows ; Bamboo Extract extracted with distilled water at 98 for 3 hrs, Mixture of Bambusae Caulis in Liquamen and bamboo Extracts (MLE) mixed at the ratio 1 to 100 (MLE100), 1 to 50 (MLE50), 1 to 20 (MLE20), 1 to 10 (MLE10), 1 to 5 (MLE5). The results were as follows ; The MLE-induced increase in rCBF was significantly inhibited by pretreatment with indomethacin (1 mg/kg, I.p.), an inhibitor of cyclooxygenase as well as methylene blue (10 , I.p.), an inhibitor of guanylate cyclase. The MLE-induced increase in BP was significantly inhibited by pretreatment with methylene blue. In cytokines production in the serum drawn from femoral arterial 1 hr after middle cerebral artery occlusion, MLE5 significantly increased production of TGF- and increased production of IL-10, but significantly decreased production of TGF- compared with control group. In cytokines production in the serum drawn from femoral arterial 1 hr after reperfusion, MLE5 significantly increased production of TGF- and IL-10, but significantly decreased production of TGF- compared with control group. AS results above. And MLE5 had anti-ischemic effect by inhibiting TGF- production, and by accelerating IL-10 and TGF- production.
