日本血吸虫病流行的湖沼地区,广大居民在生产活动中接触疫水頻繁。为防止感染,迅速杀灭水体中的尾蚴,确是有效的一种措施。現将几种常用的灭蚴剂处理疫水的試驗結果报告如后。一、单方葯剂灭蚴效果的比較 方法:①土缽(17×11厘米)分六組,各盛水2000毫升,装置口徑0.2厘米长20厘米的橡皮管一根,以备吸取試液。②各組分別放入邻苯二甲酸二丁酯水乳剂,防蚴宁油剂,五氯酚鈉水溶剂、茶子餅粉水悬剂和6％丙体666水悬剂,濃度均为10PPM,另以淸水为对照。上述各种葯剂配置后15分鈡使用。③在葯剂放入水体后1/4、1/2、1、2、4、24、48、72、168小时各自液面及液底吸取
Japan’s schistosomiasis epidemic lakes and mountains, the majority of residents exposed to frequent contact in the production activities. To prevent infection, quickly kill the cercariae in the water, is indeed a measure of effectiveness. Now several commonly used in the treatment of disinfection of water test results reported later. First, the single side effects of chemical sterilization method: ① soil bowl (17 × 11 cm) divided into six groups, each containing 2000 milliliters of water, the device diameter 0.2 cm long 20 cm rubber tube in order to absorb the test solution. ② The groups were placed in dibutyl phthalate water emulsion, anti-miracle Ningyin agent, sodium pentachlorophenol water solution, tea cake powder and 6% aqueous suspension of 666 suspension, the concentration of 10PPM , The other with water as a control. 15 minutes after the above-mentioned various pharmaceuticals are used. ③ in the water into the body after 1 / 4,1 / 2, 1, 2, 4, 24, 48, 72, 168 hours of their respective liquid and liquid absorption
