摘　　要：本研究旨在观察豆状囊尾蚴在不同状态下的超微结构。从肉联厂屠宰检验采取豆状囊尾蚴,直接剪破囊泡从中取出豆状囊尾蚴;或用含10%胆汁生理盐水培养囊尾蚴,待其从囊泡中翻出后,用扫描电镜观察和记录。位于囊泡内的头节,从其顶端观察,顶突呈伞状,皮肌柱连接小钩覆盖于头节的前端。从侧面观察,一排有鹿角样的小钩附着于顶突。4个吸盘呈洞穴状位于顶突之后分布在头节的四周。原始颈节较宽,体节较细,表面均有许多皱褶。培养后的豆状囊尾蚴可明显区分为头节、颈节、体节和囊泡区,顶突上的皮肌柱收缩,鹿角样的小钩向周围伸展,吸盘也发生环形和纵形收缩,颈节的环状收缩和体节的纵行收缩均明显可辨。豆状囊尾蚴处于不同状态时,其超微结构明显不同。The aim of the study was to observe the ultrastructure of Cysticercus pisiformis under different state.The Cysticercus pisifomis were obtained in the procedure of slaughter inspection from meat-packing plant.The Cysticercus pisiformis was taken out by cutting cyst directly,or cultured with physiologic saline containing 10% bile until evagination.Then it was observed and recorded by scanning electron microscopy.Observed from top of scolex of Cysticercus pisiformis locate in cyst,the rostellum looked like a umbrella.The cutaneous muscular columns with hamula covered the front end of scolex.Viewed from the side,a row of antlers-liking hamula adhered to the scolex.Four suckers were looked like cavity and distributed around the scolex behind the rostellum.Primary neck segments were more width and body segments less fine,in which there were lots of wrinkles in their surface respectively.The Cysticercus pisiformis cultured was divided obviously into scolex,neck,body segment and zone of cyst.When cutaneous muscular column of rostellum contracted,the antler-liking hamula extended to periphery,and the sucker also had ring-like and vertical shape contraction.It was also found evidently that the ringliking contraction appeared in neck and the lengthways contraction in body segments.The Cysticercus pisiformis under different state has distinctly dissimilar ultrastructure.
