Effects of TMB-8 on cerebral blood flow of focal cerebral ischemia in rats / 临床神经病学杂志

ABSTRACT

Objective To study the effect of TMB 8 on cerebral blood flow(CBF) of focal cerebral ischemia in the rats.Methods CBF in the middle cerebral artery occlusion after the middle cerebral artery occlusion was measured by a Laser Doppler Flowmeter. TMB 8 was administered 30 min before occlusion and 20 min after occlusion respectively.Results CBF was reduced quickly. TMB 8 0.5,1,2 mg/kg was administered 30 min before occlusion of the middle cerebral artery.The dosage inhibited the reduction of CBF,20 min after occlusion, CBF was increased by TMB 8 1 mg/kg significantly.Conclusion TMB 8 could prevent and treat the reduction of CBF in focal cerebral ischemia of MCAO in the rats,and improved the supply of blood in ischemic area.
