Wang Y, Shen LH, Chen WJ, Liu M, Li F, Liao ZG: [Expressions of Bcl-2 and Caspase-3 in the internal organs of rats when tetramine was administered]. Fa Yi Xue Za Zhi. 2006 Aug 15;22(4):241-4.
OBJECTIVE: To find whether Bcl-2 and Caspase-3 take part in the pathophysiological mechanism of tetramine toxification. METHODS: Sixty Sprague-Dawley rats were divided into normal control group, the sham poisoned group, high dose poisoned group, low dose poisoned group. High dose poisoned group were administered 1.0 mg/kg weight body tetramine by mouth, however low dose poisoned group was administered tetramine 0.1 mg/kg weight body by mouth. The rats of the sham poisoned group were administered water, and rats of normal control group were given nothing. Bcl-2 and Caspase-3 were detected by immunohistochemistry staining and the results were assessed by image analysis system. RESULTS: The expressions of Bcl-2 and Caspase-3 in all organs were similar, ie, Bcl-2 and Caspase-3 expressed obviously in all organs of high dose poisoned group; in all organs of low dose poisoned group, they were hardly detected at 30 min after administration, however, at 3 h after administration, they could be detected obviously; Bcl-2 got to peak at 6 h-3 d after administration and Caspase-3 got to peak at 24 h-3 d after administration. CONCLUSION: Bcl-2 and Caspase-3 take part in the pathophysiological procedure of tetramine poisoned rats. |
