本文选用噻嘧啶、阿苯达唑、甲苯达唑和左旋咪唑等驱虫药物，在热带地区的海南省琼海市朝烈村委会现场，采用改良加藤涂片法和试管滤纸培养法对居民普查粪检，两年连续6次化疗驱虫普治（第1年4次，第2年2次），对钩虫、蛔虫、鞭虫等土源性线虫病感染者观察疗效。结果钩虫和蛔虫感染者的疗效甚佳，钩虫的虫卵阴转率高达96．4％，残存的5例美洲钩虫感染者，克粪虫卵数大幅度减少，均在300个以内，蛔虫的虫卵阴转率高达99．3％，克粪虫卵数为24个；其疗效与选用驱虫药物和安排服药间隔时间有关。鞭虫感染者的疗效不甚理想，虫卵阴转率仅63．3％，可能与选用的几种驱虫药，只有甲苯达唑对鞭虫感染者有一定疗效，而本文的各个疗程的剂量都均偏低有关。
In this paper, pyrethroid, albendazole, mebendazole and levamisole and other deworming drugs, in the tropical region of Qionghai City, Hainan Province, Chai Lie village on the scene, using modified Kato smear and test tube filter paper on residents Census dung seized, two consecutive years of chemotherapy deworming universal (4 years in the first year, the second year 2 times), hookworm, roundworm, whipworm and other soil-based nematode infection were observed.
