Object: Cerebral vasospasm constitutes a major complication of subarachnoid hemorrhage. The pathogenesis of cerebral vasospasm is unclear, in spite of intensive investigations conducted over the past years. Even though multiple factors are proposed to be involved in cerebral vasospasm, oxyhemoglobin is one of the most important spasmogens for cerebral vasospasm that fallows aneurismal SAH.

目的：脑血管痉挛是蛛网膜下腔出血后最常见和最严重的并发症，近年来人们对SAH所致脑血管痉挛的发生机制进行了大量的研究，但迄今尚未完全阐明，众说纷纭，甚至有些观点相反，但几乎所有关于脑血管痉挛原因的报告都认为，脑血管痉挛是多种原因造成的，其中氧合血红蛋白是SAH后血管痉挛的主要启动因素之一，它对内皮细胞及平滑肌的细胞毒作用已经被报道。

Between 6th and 14th weeks afteconstricted bilateral renal arteries, the blood pressure in the majority of RHRSP with cerebral infarction was obviously higher than in RHRSP without cerebral infarction (28. 8±2. 24kPa～32. 3 ±2. 88kPa, 26. 2±2. 01～28. 3±2. 33kPa respectively). Severe hyalinosis, fibrosis, wall hypertrophy, lumen stenosis, and even microaneurysm formation in cerebral small arteries in RHRSP with cerebral infarction were found, while slight to mild arteriolosclerosis in RHRSP was found without cerebral infarction.

Results: Compared with IR group , XSOL could significantly decrease the cerebral water content, the cerebral index, the brain vascular permeability in rats of acute incomplete brain ischemia-reperfusion (P.01,P.05). Cerebral tissue morphology showed that neuronic damage of rats subjected to acute incomplete brain ischemia-reperfusion was ameliorated following administration of XSOL (2.4, 9.6g/kg). Compared with IR group , XSOL could significantly decrease the content of MDA and NO in brain tissue(P.01,P.05)and increase SOD,GSH-px activity. The levels of cerebral Glu,Asp were cut down(P.01,P.05). Conclusion: XSOL shows protective effects on cerebral ischemia-reperfusion.
