[ Method] The Cysti- cercus pisiformis were obtained in the procedure of slaughter inspection form meat-packing plant. The Cysticercus pisiformis was taken out by cut- ting cyst directly, or cultured with physiologic saline containing 10% bile until evagination. Then it was observed and recorded by scanning electron microscopy. [ Result] Observed from top of scolex of Cysticercus pisiformis locate in cyst, the rostellum looked like an 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 more width and body segments less time, 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 con- tracted, the antler-liking hamula extended to periphery that the ring-liking contraction appeared in neck and the lengthways contraction in body seg- ments. [ Conclusion] The Cysticercus pisiformis under different state has distinctly dissimilar ultrastructure.展开更多
