ABSTRACT
Objective To observe the effect of low dosage of uhrashortwave(USW) on infarction volume, B cell lymphocytoma-xl (Bcl-xl) and tumor necrosis factor alpha (TNF-?) after cerebral ischemia-reperfusion in rats and discuss its acting mechanisms. Methods Focal ischemia-reperfusion model was established in 25 rats by re- versible right middle cerebral artery occlusion with filament. The right side cerebral ischemia was lasted for 2 hours and then followed with 24 hours of reperfusion. The content of neurological deficits were evaluated by the Zea-Longa 5-degree scoring system to select rats. After surgery, the rats were divided into 3 groups blank control group, control group and USW treatment group. The brain of all rats was taken at 24 hours after reperfusion. The cerebral infarction volume, the expression of Bcl-xl and TNF-?were measured and analyzed. Results Twenty-five rats were used in the analysis of results. When compared with the control group, the infarction volume and rate in total cerebral volume of USW group significantly decreased (t = 2.54, 2.33, P
