摘要: 摘要: 目的探讨建立功能性消化不良( Functional Dyspepsia,FD) 重叠肠易激综合征( Irritable Bowel Syndrome, IBS) 动物模型的方法。方法将大鼠随机分为3 组: 空白对照组( A) ,先夹尾刺激后灌胃组( B) ,先灌胃后夹尾刺激组 ( C) ,利用行为分析仪对大鼠旷场实验进行分析,了解大鼠的焦虑、抑郁程度; 同时,取大鼠的胃窦进行组织学观察。 结果B 组的变化比C 组更加接近于人类的发病情况。与A 组相比,模型组大鼠旷场实验有统计学意义( P < 0. 05) 。两模型组之间除一般状态和旷场实验以外也存在显著性差异( P < 0. 01) 。结论大黄泻下法结合夹尾应 激法能成功建立FD-IBS 重叠征模型,夹尾刺激和灌胃按不同顺序实施均能成功建立,且先夹尾刺激后灌胃组建立 的重叠征模型优于先灌胃后夹尾刺激组。

Abstract: Abstract: Objective To observe the ethological and pathological changes of the rats of parkinson’s disease induced by injection of lactacystin into the substantia nigra. Method Lactacystin /DMSO ( 8 μg /2 μL) was stereotacticly injected into the left substantia nigra of model group,while the DMSO was injected into the left substantia nigra into DMSO group. Apomorphineinduced rotation test was performed on day 6, 13 and 20 after the injection. Immunohistochemical staining was conducted to test the aggregation of α - synuclein and the number of TH( tyrosine hydroxylase) positive neurons. Result The rats of model group revolved rightward and the frequency exceed 7 r /min. Aggregation of α - synuclein was revealed in the paraffin section of substantia nigra of model rats and the number of TH-positive neurons were significantly reduced. Conclusion Rats model of PD can be established by stereotactic injection of lactacystin into the substantia nigra.
