Abstract:
Objective To observe the effect ofShenmal injection on vascular endothelial function after cerebral ischemia reperfusion in rats.Methods 30 rats were randomly divided into a sham operation group, a model group and aShenmal group, with 10 in each. Except the sham operation group, animal models of cerebral ischemia reperfusion injury were established by the right internal carotid artery occlusion of middle cerebral artery. Then shenmal injection was given to theShenmal group, 2 ml/100 g Sodium Chloride was given to the other groups, once per day, for successive 7 days. Endothelin-1 (ET-1), nitric oxide (NO), nitric oxide synthase (NOS), serum high sensitivity C-reactive protein (hs-CRP), and homocysteine (Hcy) were tested. Results In Shenmal group, ET-1(126.10 ± 6.07 ng/mlvs.105.41 ± 0.09 ng/ml), hs-CRP (15.93 ± 2.79 mg/Lvs. 9.33 ± 1.32 mg/L) and Hcy (11.01 ± 0.98 μmol/Lvs. 8.13 ± 0.46 μmol/L) were decreased after the treatment, while NOS (168.87 ± 9.25 U/mlvs.242.25 ± 10.36 U/ml) and NO (84.03± 6.02vs.102.42± 5.05) were increased after the treatment with statistical difference(P<0.05).ConclusionShenmalinjection can improve NOS activity and promote the synthesis of NO, decrease the level of plasma ET-1, hs-CRP and Hcy, reduce endothelial inflammatory exudation, and prevent vascular endothelial dysfunction caused by cerebral ischemia reperfusion injury.
