Abstract: ObjectiveTo investigate the effects of morroniside on IL-1β in rat cortex with focal cerebral ischemia/reperfusion.MethodsThe animal model was induced by occlusion of middle cerebral artery with suture embolus, ischemia for 30 min, and reperfusion for 72 h in rats. The content of IL-1β was detected with enzyme linked immunosorbent assay(ELISA).ResultsCompared with sham group, the content of IL-1β increased obviously in model rat. Compared with model group, morroniside(30 mg/kg, 90 mg/kg, 270 mg/kg) and colchicine (0.06 mg/kg) decreased the content of IL-1β significantly (P<0.001).ConclusionMorroniside may protect the cortex from inflammatory factor IL-1β.
