An Observation on Ethological and Pathological Changes in Rat of Parkinson's Disease Induced by Lactacystin

  • Online:2013-08-31 Published:2014-05-13

摘要: 摘要: 目的用乳胞素诱导SD 大鼠建立帕金森病( Parkinson's Disease ,PD) 模型,并进行行为学及病理学观察。方 法乳胞素/DMSO( 8 μg /2 μL) 定向注射模型组大鼠左侧脑黑质内,DMSO 组注射DMSO。于手术后第6、13 和20 天采用阿朴吗啡旋转实验检测行为学改变,用免疫组织化学法检测脑组织切片,进行TH 阳性细胞计数及观察α 突 触核蛋白( α - synuclein,α - syn) 聚集情况。结果模型组中SD 大鼠向右旋转速度大于7 r /min; 脑组织切片中可 见α - syn 聚集。与对照组相比,模型大鼠脑组织切片中TH 阳性细胞数显著减少( P < 0. 05) ,模型组第10 天处死 大鼠与第20 天处死大鼠相比,TH 阳性细胞数差异具有统计学意义( P < 0. 05) 。结论乳胞素单侧黑质内注射可 以诱导大鼠PD 模型。

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. Key words: Parkinson’s disease; lactacystin; animal model

Key words: Parkinson’s disease, lactacystin, animal model, SD rat
