Objectives : This study was designed to investigate the effects of Sasim-tang (SST) on proinflammatory cytokine production in a photothrombotic ischemia mouse model. Methods : Photothrombotic ischemia was induced in stereotactically held male Balb/c mice using rose bengal (10 mg/kg) and cold light. The target of photothrombotic ischemic lesion was 1 mm anterior to bregma and 3 mm lateral to midline with 2 mm in diameter, which are decreased by oral administration of SST. Results : SST protected ischemic death of brain cells through inhibition of pro-inflammatory cytokines production and catalytic activation of caspase-3 protease in photothrombotic ischemia mouse model. Conclusions : The results of this study suggest that SST can have protective effects on brain cell damage in a photothrombotic ischemia mouse model.
