在血吸虫病流行的湖沼地区,由于生产劳动等需要,农民经常与疫水接触,因而有发生血吸虫感染的机会。目前国内外尚缺乏防护效能高、效力持久、无副作用、使用方便、价格低廉的防护方法。我们研究用氯硝柳胺浸渍衣着,防止尾蚴钻入皮肤,并用氯硝柳胺制成涂肤剂“防蚴笔”涂在裸露的皮肤上以防御感染,均取得了满意的结果。氯硝柳胺浸布是将布(裤、袜、衣着等)浸入1%氯硝柳胺碱性溶液后,再用稀盐酸中和即成。日本血吸虫尾蚴接触药布即死,故不能透过,因而起到保护作用。氯硝柳胺吸附在织物纤维上,犹如色布上的染料经久不 In the lakes and marshes where schistosomiasis is endemic, because of the need for productive labor and other reasons, peasants often come into contact with polluted water and thus have an opportunity to develop schistosomiasis. At present, there is still a lack of protective measures with high protective efficacy, lasting efficacy, no side effects, convenient use and low price at home and abroad. We studied the use of niclosamide impregnated clothing to prevent cercariae into the skin and made with niclosamide skin agent “anti-lacteal pen” painted on bare skin to prevent infection, have achieved satisfactory results. Niclosamide cloth is immersed in cloth (pants, socks, clothing, etc.) into 1% niclosamide alkaline solution, and then dilute hydrochloric acid and Serve. Schistosoma japonicum cercariae contact with the drug that is dead, it can not through, which play a protective role. Niclosamide adsorbed on the fabric fibers, as if the dye on the colored cloth is not durable
