Abstract:
Objective To observe the preventive and therapeutic effect of Baimai Ointment on stoke,and explore the principle of promoting blood circulation and removing blood stasis.Method By dermal administration,the crude drug contents of Baimai Ointment given to rats were 0.075,0.150,and 0.300 g/kg respectively.Focal cerebral ischemic model was induced by the middle cerebral artery occlusion (MCAO),and the preventive and therapeutic effect of Baimai Ointment was evaluated.The degree of hematoma absorption in rats was measured to observe the effect on promoting blood circulation and removing blood stasis of Baimai Ointmnent.The acute blood stasis model and carotid thrombosis model were established in rats to study the effects on blood viscosity and thrombosis time.Results Baimai Ointment had no significant prevent effect on stroke in rats.It effectively improved behavior coordination in stroke model rats.It also significantly decreased the area of hematoma on rats,speeded up the repairment of local demage.After administration of Baimai Ointment,blood viscosity of blood stasis model rats was obviously decreased,while thrombosis time was effectively prolonged on carotid thrombosis model.Conclusion Baimai Ointment can significantly improve the behavior coordination in stroke model rats,plays a significant role in treatment,but no significant preventive effect,a preliminary study shows that the possible therapeutic principles may be promoting blood circulation and removing blood stasis.
