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 h龙江血居吸虫童虫的鲫鱼苗也进行了组织学和组织化学观察
A detailed histological and histochemical observation was carried out on the folded radish snail cultured in the laboratory containing artificial infection of Longjiang blood stinging cercariae.Longjiang blood sturgeon cercariae development process can be divided into the following five stages: Stage, embryo stage, stage of cercopithelial embryo, stage of mature cercariae, stage of mature cercariae. There are 3 types of glands in mature cercariae: a pair of glands immediately after constriction of the head produce secretion of acidic mucopolysaccharide Class substances; the back of the body 3 pairs of larger glands secreted mucoid-rich substances; body of the other 5 pairs of glands secreted rich in glycogen substances.In addition, the laboratory culture containing longjiang bloodworm adult And eggs of goldfish tissues and organs, containing 0.5 ~ 2 h Longjiang bloodworm schistosomula carp fry also conducted histological and histochemical observations
