摘要: 成年雄性大鼠72只,分为盐水组和给药组(注射D-半乳糖胺)。给药后 1、2、3、4、5、7和10天取甲状腺进行组织化学和免疫组织化学染色。结果表明,给药组甲状腺滤泡发生明显变化。给药后第1~3天,滤泡腔略变大,滤泡细胞变矮,胶体增多;除ATPase外,RNA、ACP、SDH、G6PDH和PO反应均减弱;滤泡细胞内胶体小滴数量减少;腔内T3、T4免疫反应物含量降低其中以第2天为最明显。给药后第5天,上述各项指标比盐水组均增强、增多。自给药后第7天起,各项指标均趋向恢复。结果提示注射D-半乳糖胺后,甲状腺滤泡的变化似与肝损伤和肝再生过程存在着密切关系。

Abstract: 72 adult male rats were divided into 2 groups, i. e. control group and D-galactosamine administration group. The thyroids were removed at different time intervals (1, 2, 3, 5, 7 and 10 days) after injecting D-galactosamine, and then stained with histochemical and immunohistochemical PAP method. The findings were as follows. On the first to 3 rd day after injecting D-galactosamine, the lumen of the follicles were enlarged, follicular epithelial cells became short, the amount of colloid deposits were increased. Except the ATPase, the reac-tions of RNA, ACP, SDH, G6PDH and PO Were Weaker than those of the control group. Both of the amount of colloid droplets and the Immunoreaction substances of T3 and T4 declined. Although on the 5 th day, all of the indexes increased, they returned to normal level after 7 days. The results were suggested that the changes of the thyroid follicles following injecting D-galactosamine were closely related to the iniury and the regeneration process of liver.
