海群生对丝虫成虫及微丝蚴的疗效已被我国医学界所肯定。目前在大规模防治工作中,一般均采用1--3日短程疗法,所用海群生总量为1.5--4.8克不等。近来,不但对马来丝虫而且对班氏丝虫病者,正广泛地采用一次(海群生1.0--1.5克)疗法。根据有关文献及我们的实验观察,这种疗法对马来丝虫的成虫及幼虫作用较为完全,而对班氏丝虫则略逊。一般的说,治疗后的立即疗效,在马来丝虫患者为70%左右,而在班氏丝虫患者为40--55%;微丝蚴的减少率,在马来丝虫患者为90%以上,在班氏丝虫患者为80%左右。虽然短程疗法的推广时间尚短,远期疗效的报告还不多,但从治后连绩观察六个月的几篇报告来看,疗效是稳定的,而且 Enthusiasm of filarial adults and microfilaria oncomelania efficacy has been affirmed by the medical profession in our country. Currently in large-scale prevention and control work, generally use 1 - 3 days of short-range therapy, the total amount of seaquakes used for 1.5 - 4.8 grams. Recently, there has been a widespread adoption (1.0-1.5 g) of therapies not only for Malayan filariasis but also for Bancroftian filariasis. According to the relevant literature and our experimental observations, this treatment is more complete on adults and larvae of Malayan filariasis while slightly less on Bancroftian filariasis. In general, the immediate curative effect after treatment was about 70% in patients with Malayan filariasis and 40-55% in patients with Bancroftian filariasis; the rate of reduction of microfilarens was 90% in malayian filariasis % Or more, in 80% of patients with Bancroftian filariasis. Although the promotion of brachytherapy is still short, the long-term efficacy of the report is not much, but after the treatment of consecutive reports observed six months of several reports, the effect is stable, and
