Abstract

The study was designed to investigate the effects of Leonuri herba extract (LHE) on the change of regional cerebral blood flow (rCBT and cytokines production (IL-1${\beta}$, TNF-${\alpha}$, IL-10, TGF-${\beta}$) in ischemic rats. The results were as follows : The rCBF was significantly and stably increased by LHE (10 mg/kg, i.p.) during the period of cerebral reperfusion, which contrasted with the findings of rapid and marked increase in control group. In cytokine production of serum by drawing from femoral arterial blood at 1 hr after middle cerebral arterial occlusion, experimental group (LHE 10 mg/kg treated group) was significantly decreased IL-l${\beta}$ production, and increased TGF-${\beta}$ production compared with control group. In cytokine production of serum by drawing from femoral arterial blood at 1 hr after reperfusion, experimental group was significantly decreased IL-1${\beta}$ production compared with control group. IL-10 and TGF-${\beta}$ production of sample group were significantly increased compared with control group. These results suggested that LHE was significantly and stably increased regional cerebral blood flow by inhibited IL-1${\beta}$ production, and accelerated IL-10 and TGF-${\beta}$ production.
