摘要: 目的: 探讨水蛭地龙萃取液对急性脑梗死粘 结合蛋白多糖-1 的表达及可能的抗炎机理。 方法: 采用线栓法制作大鼠大脑中动脉(MCAO) 阻断模型, 用 HE 染色、免疫组织化学方法, 观察水蛭地龙 萃取液对脑缺血 2 h 再灌注 4、24、72 h 和 7 d 的粘 结合蛋白多糖-1阳性细胞的分布 、数量及缺血脑组 织的病理变化。结果: 水蛭地龙萃取液组各时间点 均可上调粘结合蛋白多糖-1 的表达(P<0.01), 其 中 72 h 最明显;水蛭地龙萃取液治疗 24、72 h 时间 点较对照组多核炎性细胞的浸润明显减少, 而4 h点两组炎性细胞浸润均不明显, 7 d 水蛭地龙萃取 液组能明显减少单核细胞的浸润。结论: 水蛭地龙 萃取液可以上调粘结合蛋白多糖-1的表达, 粘结合蛋白多糖-1的上调能减少炎性细胞的浸润。

Abstract: AIM: To investigate the effect of hirudo and earthworm liquor extract on the expression of synde-can-1 in focal cerebral ischemia reperfusion rats and the relationship between syndecan-1 expression and cellists underlying antiinflammatory mechanism.METHODS: The MCAO modelsof rats were built with the intraluminal filament occlusion.Rats' brains were cut at the levels of the hippocampus as the templates.Immunohistochemistry staining and HE staining were used to facilitate the obser-vation of the distribution and the quantities of cells with expression of syndecan-1 and the pathological change of MCAO ischemia 2 h reperfusion 4, 24, 72 h and 7 d with hirudo and earthworm liquor extract or saline treatment, respectively.RESULTS: Hirudo and earthworm liquor extract could upregulate the expression of syndecan-1 on ischemia/reperfusion in rats' brains, especially at 72 h. The numbers of syndecan-1 cells got peak, hirudo and earthworm extract liquor could downregulate polynucle-ation inflammatory cells at 24 and 72 h.The expression of inflammatory cells in both hirudo and earthworm liquor extract group and saline group at 4 h was not significant. Hirudo and earthworm extract liquor downregulated the monocytic inflammation cells infiltration at 7 d.CONCLUSION: Hirudo and earthworm liquor extract can up-regulate the expression of syndecan-1on ischemia reperfu-sion in rats' brains.The upregulation of syndecan-1 can decrease inflammatory cell infiltrate.

Key words: hirudo and earthworm liquor extract, syndecan-1, cerebral ischemia, reperfusion damage
