摘要: 目的:观察肝硬化大鼠中缝背核五羟色胺(5-hydroxytryptamine,5-HT)能神经元以及双标神经元的表达变化。方法健康雄性Wistar大鼠20只,分为模型组和对照组各10只,模型组大鼠经皮下注射CCl4结合饮用酒精14周,对照组皮下注射等剂量的生理盐水。应用5-HT免疫组织化学及5-HT复合NADPH-d免疫组织化学染色双标方法,观察中缝背核5-HT能神经元以及双标神经元的表达变化。结果与对照组相比,模型组大鼠中缝背核5-HT能神经元的数量未见明显变化,直径明显变小,模型组免疫反应阳性强度明显较对照组增强,神经元的光密度(0.54±0.04)vs(0.48±0.04)(P<0.01);双标神经元未见明显变化。结论肝硬化影响了大鼠中缝背核5-HT能神经元。

Abstract: Objective To study the expression of 5-hydroxytryptamine( 5-HT ) and double-labeled neurons in dorsal raphe of cirrhosis rats. Methods The healthy male Wistar rats were divided into model and control groups(n=10). Within 14 weeks,model group rats were subcutaneously injected by CCl4 plus drinking ethonal. Control group rats received subcutaneously injection of sodium chloride. 5-HT immunohistochemistry and 5-HT immunohistochemistry combined with NADPH-d staining were used to detect the expression of 5-HT and double-labeled neurons in dorsal raphe of rats. Results The average diameter 5-HT neurons in dorsal raphe decreased significantly in the model group compared with that of control group. The optical density value of 5-HT neurons in dorsal raphed increased sinificantly in the mode of group(0. 54 ± 0. 04)compared with that of control group(0. 48 ± 0. 04)(P <0. 01). The quantity of 5-HT neurons and the double-labeled neurons in dorsal raphe hasd no significant difference between two groups. Conclusion Cirrhosis influenced 5-HT neurons in dorsal raphe of rats.
