摘要
本文观察了小鼠母体氟暴露对仔代胸腺酶组织化学与超微结构的影响,结果显示:(1)酶组化观察中发现高剂量组仔鼠胸腺AKP、ACP、Ca^(2+)-ATP酶活性显著降低;(2)高剂量染氟组仔鼠胸腺电镜下可见上皮细胞、胸腺细胞核染色质固缩成块状且分布不均;线粒体嵴断裂或消失;上皮细胞与胸腺细胞之间连接松弛,间隙增大等。表明氟化物可损伤胸腺细胞,胸腺上皮细胞,直接或间接影响胸腺细胞的发育,进而导致后代的免疫功能降低。
In order to study the relation between fluoride and immune function of boby, the effects of maternal exposure to fluoride on the thymic ultrastructure and enzyenehistochemistry for fetus mice were observed in this paper. Results showed that at the high dose NaF group, the mucleus chromatin of thymic epithelial cells and their crest loss or despeared; the mitochondria were swelling, the density of plasma decreased and their crest loss or dispeared; the bond of epithelial cells with thymo-cytes became loose and the gap between them became wide.The result of enzyenehistochemistry showed that the activity of AKP, ACPand Ca - ATPase of thymus in fetus mice decreased markedly in epithelial reticular cell or thymocyte compared with the control. This indicated that fluoride may injure thymic epithelial cell and thymocyte, and affected direct or indirectly growth of thymocyte.
