本文报道用酚酶组织化学和雌虫形态学相结合的方法，分别对一次口服吡喹酮和硝硫氰胺６０ｍｇ／ｋｇ剂量治疗的实验兔，停药后不同时间解剖，取出雌虫和对照组的雌虫同时进行酚酶反应，测量虫体长度和计数雌虫虫卵数．实验发现；两药均随停药时间延长酚酶反应逐渐减弱以致呈可疑阳性，４８ｈ时几乎是阴性反应．随停药时间的延长虫体子宫虫卵数逐渐减少，出现变性虫卵或只见卵黄腺颗粒或雌虫子宫内无虫卵．虫体长度逐渐缩短。
This article reports the combination of phenylase histomorphometry and morphological females, respectively, once orally administered praziquantel and nitrocytamine 60mg / kg dose of experimental rabbits, after stopping the anatomy at different times, remove the female and control The females of the group were subjected to phenolic reaction at the same time, and the length of the parasites and the number of female eggs were counted. The experimental results showed that both drugs were suspiciously positive with the prolongation of the prolongation of phenylazine reaction, almost negative reaction at 48h. With the extension of withdrawal time of worms uterus eggs gradually reduce the number of degenerated eggs or see only the egg yolk glands or uterus no eggs. Parasites gradually shorten the length.
