【摘要】 目的　对紫贻贝消化盲囊组织的显微及亚显微的结构进行观察研究以进一步探索紫贻贝镉中毒的机理。方法　以组织学和电镜方法观察盲囊管腔及上皮细胞膜系统的损伤情况。结果　镉诱导大量吞噬细胞出现导致盲囊管腔堵塞 ,上皮细胞的膜系统及间质结缔组织随着镉浓度增加受损的程度增大。结论　镉可致紫贻贝成体消化盲囊形态结构的损伤更多还原

【Abstract】 Objective To explore the toxic mechanism of cadmium by the research of microstructure and ultrastructure of Mytilus Edulis digest blind sac organization. Methods To observe the damage of blind sac and epithelium membrane system with the aid of histology and electron microscope. Results A number of phagocytes induced by cadmium lead to the blocked blind sac, the damage degree of membrane system and connective tissue was increased with the increase of density of cadmium. Conclusion Cadmium can cause the damage of the morphologic structure of the adult Mytilus Edulis digestive blind sac.更多还原
