    摘要:

    本试验通过电子显微镜观察家蚕添食氟化物后体壁及中肠的组织变化,结果显示体壁及中肠都受到不同程度的破坏,体壁上皮细胞出现空泡,严重在外表皮层出现沉积物,中肠病变更为明显,细胞层结构松驰,细胞内出现空泡,线粒体空化,内质网膨胀化,核膜退化,核质凝团状。本文从组织学角度探讨了氟化物引起家蚕中毒的机制。为蚕桑生产中大气污染的防治提供部分理论依据。

    Abstract:

    This experiment was conducted observe,through electron microscopy,the struc-tural changes in the integument and mid-gut of the silk worm fed with fluoride.The resultsshowed various degrees of damage in the integument and mid-gut.Vacuoles appeared inthe epithlium of the integument and precipitates appeared in the outer epidermis in some se-vere cases.The pathological changes in the mid-gut were more obvious:the structure of thecell layer became loosened,the cell vacuolated,the mitochondria void,the endoplasmicreticulum swollen,the nuclear membrane degenerated and the nucleoplasm agglomerated.The mechanism of the fluoride poisoning to the silk worm was discussed in relation to pro-viding scientific basis for the control of air pollution in sericulture production.
