| 摘 要： | 目的探讨大鼠慢性毒鼠强中毒后脑部细胞色素C（Cyt C）的表达情况，为毒鼠强中毒案件的法医学鉴定提供新的指标。方法建立大鼠毒鼠强慢性中毒模型，用免疫组化与图像分析技术分别检测中毒后不同时间大鼠脑皮质、海马Cyt C的表达。结果对照组大鼠脑内Cyt C有微量表达，实验组大鼠中毒后30min Cyt C表达开始增强，24h到达高峰，3d后开始下降，10d后基本恢复正常。结论Cyt C表达的规律性变化可望成为慢性毒鼠强中毒的法医学鉴定依据，并可为临床推断慢性毒鼠强中毒的不同时期提供证据。

| Abstract: | Objective To investigate the evidence for the judgement on legal cases of intoxation by tetramine. Methods Fifty rats given tetramine by lavage were sacrificed at different time after intoxation. The expression of Cyt C was detected by immunohistochemistry, and the reasults were assessed by an image analysis system. Results There was a slight expression of Cyt C in control group. In intoxation group the expression of Cyt C increased after the rats were given tetramine for 30 minutes; it reached the peak at 24 hours after intoxation and kept up the level for 3 days, then it began to decrease and returned to the control level in 10 days. Conclusion The regular change of Cyt C expression might be a useful sign for assessment in legal cases of intoxation by tetramine. |
