| 摘 要： | 牛肝片吸虫的成虫体表有环行排列的、呈“牛舌状”的棘,其顶部有?数个齿;迷走幼虫体表无体棘,仅有环状排列的、粗细不一的皱纹,其头锥较长,约为虫体的1/2,口腹吸盘是圆形,上有细皱纹和数个乳突。受损职管的大部分功能消失殆尽。而增生小胆管则功能旺盛。浸润的嗜酸粒细胞、淋巴细胞功能较活跃。浸润的细胞中未见巨噬细胞。探讨了虫体与胆管损伤的关系。

| Abstract: | There are spines in cycle arrangement on surface of the adultworm of Fasciola hepatica. The spine looks like a "cattle tougue" and hasten teeth or so on his top. No spine but cycle-arranged wrinkles in. dif-ferent thickness are found on the surface of the migrating larvae. The headcone of the larva is half as long as the body, its oral and belly suckersare circular, and there are wrinkles and some papillae on it. The functionof the epithelioid cells of damaged bill duct nearly lost, while those ofhyperplastic bill duct function vigorously. In the infiltrating cells, theacidophils and lymphocytes function. somewhat actively but no macrophagesare found. The relationship between worm and injuries of bill duct wasdiscussed. |
