摘要: 目的 检测不同时程海洛因依赖大鼠海马、杏仁核和额叶皮质discs大同源物4(discs large homolog 4,DLG4)的蛋白表达,探讨海洛因依赖对突触后致密结构的影响。 方法 采用腹腔内递增注射海洛因的方法,建立海洛因依赖的大鼠模型,用免疫组织化学法检测海洛因依赖9、18和36 d大鼠海马、杏仁核和额叶皮质DLG4蛋白的表达,并与对照组进行比较。 结果 随海洛因依赖时间的延长,海马、杏仁核和额叶皮质DLG4蛋白的表达逐渐降低。 结论 海洛因依赖可影响海马、杏仁核和额叶皮质突触后致密结构,并随依赖时间的延长,影响更加明显。

Abstract: Objective To observe the expression of discs large homolog 4 (DLG4) protein in hippocampus, amygdala and frontal cortex of rats and evaluate postsynaptic density in heroin dependence. Methods The rat heroin dependent model was established by increasing intraperitoneal injection of heroin. DLG4 proteins in hippocampus, amygdala and frontal cortex of heroin dependent 9, 18, 36 days rats were detected with immunohistochemical staining and compared with that in the control group. Results DLG4 proteins in hippocampus, amygdala and frontal cortex were gradually reduced with extension of heroin dependent time. Conclusion Heroin dependence can affect postsynaptic density of hippocampus, amygdala and frontal cortex. The changes become more apparent with extension of heroin dependence time.
