摘要
应用焦锑酸钾亚细胞定位技术研究氟中毒蚕中肠细胞钙离子变化动态,在透射电镜下观察到由多层膜结构组成的同心圆钙结晶体结构,这种结晶体的结构和数量随食下桑叶含氟量的增加而变化,与家蚕氟中毒有密切的关系。
The specific spherocrystals of calcium salts with numerous concentric layers were observed in the midgut cells of fluorosis silkworm larvae Bombyx mori by means of in situ precipitation with an improved potassium pyruantimonate technique and electron microscopy. It was also found that the structure and number of the spherocrystals were changed as the increase of fluoride concentration in the ingested mulberry leaves, which was believed to be related to the detoxification of fluoride in the midgut cells of silkworm larvae.
