作者用小鼠感染旋毛虫后分别在肠道期、移行期和包囊期用左旋咪唑(Levamisole)和甲苯咪唑(Mebendazole)进行了比较实验治疗。实验用6周龄雄性小鼠(IGR系)共115只,每组5只分别饲养于塑料笼内,旋毛虫(USA系)经传代接种后将小鼠的全部肌肉用盐酸、胃蛋白酶消化法处理,分离感染期幼虫,并将感染期幼虫放入含3%的明胶生理盐水中,用胃内投入法每鼠感染300条。 After the mice were infected with Trichinella, mice were treated with Levamisole and Mebendazole in the intestinal phase, transitional period and cyst-phase respectively. A total of 115 male 6-week-old male mice (IGR strain) were housed in plastic cages respectively. Trichinella spiralis (USA strain) were inoculated with the whole muscle of mice with hydrochloric acid and pepsin digestion The larvae of infection were isolated and treated, and the larvae of infection were placed in 3% gelatin saline solution. Infected by intragastric administration, 300 mice were infected.
