摘要
对在实验室培养的含有人工感染龙江血居吸虫尾蚴发育各期的折叠萝卜螺进行了详细的组织学和组织化学观察 .龙江血居吸虫尾蚴发育过程大致可分以下 5期 :胚细胞期、胚球期、尾蚴胚体期、成熟尾蚴前期、成熟尾蚴期 .成熟尾蚴体内的腺体有 3种类型 :紧接在头器缢缩之后的一对腺体分泌富含酸性粘多糖类物质 ;体中背部 3对较大腺体分泌富含粘蛋白类物质 ;体中部另外有 5对腺体分泌富含糖原类物质 .此外 ,对实验室培养的含龙江血居吸虫成虫和虫卵的金鱼组织器官、含侵入0 .5～ 2
Histochemical and histological observations on different larval stages and the adult of S. lungensis obtained from laboratory are made. Developmental stage of S. lungensis may be divided into following five stages: germinal cell stage; germ ball stage;cercariae embryo stage; prematured cercariae stage and matured cercariae stage. There are three types of unicellar glands in the body of matured cercariae: one pair of glands right after cephalic organ contains Alcianblue postive material, upper three pairs of glands situated in the middle of body contains Southagecarmine postive material, other five pairs of glands that below these three pairs of glands contains PAS postive material.There are organ containing a little PAS postive material in the middle of the worm that infected 30~120 minute in Carassius sp fingerlings, but no glands containing Alcianblue and Southagecarmine postive material. Caeca of adult is abundant with hepatin material, testis and ovary contains protein material.
