硝氯酚作用 (1)羊 硝氯酚是比較理想的驅(qū)肝片形吸蟲(chóng)藥,3mg/kg量?jī)?nèi)服對(duì)肝片形吸蟲(chóng)成蟲(chóng)有效率為93%~100%。對(duì)未成熟蟲(chóng)體,則周齡愈小用量愈大,如4mg/kg量,對(duì)8周齡蟲(chóng)體有效率58.4%,12周齡蟲(chóng)體100%;8mg/kg量,對(duì)4周齡蟲(chóng)體有效率92.5%,6周齡蟲(chóng)體99.7%,8周齡蟲(chóng)體99.7%,16mg/kg則對(duì)4周齡蟲(chóng)體100%有效。有人對(duì)硝氯酚進(jìn)行廣泛的臨床試驗(yàn),12周齡蟲(chóng)體有效量為2.7mg/kg(冶療安全指數(shù)4.4);6周齡蟲(chóng)體為6mg/kg(治療安全指數(shù)2.0);4周齡蟲(chóng)體為8mg/kg(治療安全指數(shù)1.5)。根據(jù)上述試驗(yàn),證明氯硝酚對(duì)未成熟蟲(chóng)體的有效劑量,其安全范圍很低,實(shí)際上,6mg/kg量已能使羊產(chǎn)生不良反應(yīng),故對(duì)未成熟蟲(chóng)體無(wú)臨床實(shí)用意義。(2)牛硝氯酚對(duì)牛肝片形吸蟲(chóng)的驅(qū)除作用與羊肝片形吸蟲(chóng)相似。3mg/kg量對(duì)成年黃牛肝片形吸蟲(chóng)成蟲(chóng)滅蟲(chóng)率為98.74%,對(duì)犢牛成蟲(chóng)滅蟲(chóng)率僅為76%~80%。水牛內(nèi)服1~3mg/kg也有極佳療效,但3mg/kg量對(duì)牦牛無(wú)效,10~12mg/kg量驅(qū)蟲(chóng)率達(dá)100%,驅(qū)除肝片形吸蟲(chóng)童蟲(chóng)需用16~20mg/kg劑量,但此時(shí)牛已出現(xiàn)中毒而無(wú)實(shí)用意義。某些臨床試驗(yàn)認(rèn)為,硝氯酚對(duì)前后盤(pán)吸蟲(chóng)移行期幼蟲(chóng)可能有些作用,因?yàn)榛夹笥盟幒篌w況明顯改善。(3)豬3~6mg/kg量?jī)?nèi)服,對(duì)肝片形吸蟲(chóng)成蟲(chóng)驅(qū)除率幾近100%,而且動(dòng)物耐受良好。
