摘要: 目的: 观察醒脑静注射液(XNJI) 对脑缺血再灌注家兔花生四烯酸代谢的影响,并探讨其脑保护机制。方法: 将健康家兔20 只以“ 四管闭塞法”及再开放颈动脉建立家兔急性全脑缺血及缺血再灌注动物模型,造模后分为生理盐水组(n = 10)和醒脑静组(n = 10),于缺血前和再灌注前,生理盐水组家兔静脉注射生理盐水1 ml· kg-1,醒脑静组静脉注射醒脑静注射液l ml·kg-1。观察血浆、脑组织中血检索B2(TXB2)、6-酮-前列腺素F1a(6-Keto-PGF1a)含量与比值的变化,并观察脑超微结构变化。结果: 醒脑静组与生理盐水组同时相相比血浆和脑组织TXB2含量、TXB2/6-Keto-PGF1a比值明显降低(P<0.05),醒脑静组脑组织超微结构病理改变不明显。结论: XNJI 通过抑制TXB2合成、促进6-Keto-PGF1a生成而下调两者比值,这可能是其减轻脑缺血再灌注损伤的又一作用机制。

Abstract: AIM:METHODS: The acute complete cerebrali schemia model and the ischemia-reperfusion model were made by eluding four-vessel, both bilateral carotid an dvertebral arteries, and removing the occlusion of bilateral caroli at the end of 30 minutes ischemia. Control group(A) was intravenously infused. 9% saline (1 ml· kg-1 before ischemia and before reperfusion, but XNJI group(B) were inlused XNJI (1 ml· kg-1) The contents and of 6-KETO-PGF1a in both plasma and braintissue were separalely measured with radioimmunoassayIe ore isehemia. 30 min after ischemia and 30 min, 1 h and 2 h after reperfusion. Cerebral ultrastruc true changes were observed at the end of experiment.RESULTS: Forthe XNJI group, compared with control group, TXB2 > content and the radio of TXB2/6-KETO-PGFLA in both plasma and brain tissue decreased (P < 0.05). The observation of the pathologic changes of ultrastruc true in rain tissue showed that the injury was relieved in XN JI group.CONCLUSION: XNJI can effectively decrease the radio of TXB2/6-KETO-PGF1a, by decreasing the synthesis of TXBand accelerating the growing of 6-KETO-PGF1a, and it maybe another mechanism in protecting the brain from ischemia and reperfusion injury.
