The present study investigated the therapeutic window of Qingkailing injection for focal cerebral ischemia/reperfusion in mice. Animals underwent middle cerebral artery occlusion and were injected with Qingkailing （1.5, 3, 6 mL/kg）. Infarct volume and neurological function were assessed after 24 hours of ischemia. In addition, to establish the therapeutic time window, mice were injected with 3 mL/kg Qingkailing at 0, 1, 3, 4, 6, 9 and 12 hours after occlusion. Results revealed that Qingkailing injection significantly reduced infarct volume and improved neurological function in model mice after cerebral infarction for up to 9 hours, demonstrating that the therapeutic window of Qingkailing injection can extend to 9 hours for cerebral ischemia/reperfusion in mice.展开更多
