作者等用体外培养方法观察了左旋咪唑和伊维菌素的抗细粒棘球蚴原头节的效果,并进一步用光学显微镜和电镜观察左旋咪唑和伊维菌素对原头节成活率和超微结构的影响。原头节系从自然感染的绵羊肝包囊中采集。培养液为199,含青霉素100IU/ml和链霉素100μg/ml。在盛有199培养液10ml的培养管中培养1500只原头节,培养温度为37℃。伊维菌素和左旋咪唑均用1％二甲亚 The authors observed the effect of levamisole and ivermectin against the protoscoleces of Echinococcus granulosus in vitro by using in vitro culture method and further observed the survival rate and the survival rate of protoscolei by levamisole and ivermectin by light microscope and electron microscope Effect of ultrastructure. Protozoan nodules were collected from naturally infected sheep liver cysts. The culture medium was 199, containing penicillin 100IU / ml and streptomycin 100μg / ml. A total of 1500 culture heads were cultured in a culture tube containing 199 ml of culture medium at a culture temperature of 37 ° C. Ivermectin and levamisole are used 1% dimethyl sulfoxide
