An evaluation of praziquantel on rabbit liver cirrhosis due to schistoso-miasis according to pathological changes was reported. Rabbits were treated 18 weeks after infection with praziquantel 100mg/kg/day for 2 days. All cured rabbits showed an excellent recovery 20-36 weeks after treatment with favorable pathological changes: i.e. ,(1)disappearance of vasodilatation, with decrease of hepatic arterioles and increase of portal branches; (2) disappearance of black-brown color, nodular appearance and hard feeling;...

Results indicated that praziquantel was a drug of choice in treatment for liver cirrhosis due to schistosomiasis.( Acknowledgmemt of support from the UNDP/World Bank/WHO Special Program for Research and Training in Tropical Diseases ) 用肝脏血管造型和病理组织学方法观察吡喹酮对家兔日本血吸虫病肝硬化的影响。感染尾蚴后18周,用吡喹酮100mg/kg/日进行两天治疗,所有治愈家兔肝脏血管模型、病理形态及组织学的异常变化均在停药后20~36周得到很好恢复,提示吡喹酮是一个治愈血吸虫病肝硬化较为理想的药物。 SOD activity levels in the peripheral blood cells of 19 cases of early schistosomia- sis, 43 cases of late schistosomiasis, 9 cases of late schistosomiasis who have been essentially cored and 30 cases of healthy persons wfere determined.The results showed that SOD activity is 98 3U in patients with early schisto-miasis, 486U in patients of late schistosomiasis, 617U in patients of late schistosomiasis who have been essentially cured, and 1,411U in healthy persons, respectively.There exists a significant difference... SOD activity levels in the peripheral blood cells of 19 cases of early schistosomia- sis, 43 cases of late schistosomiasis, 9 cases of late schistosomiasis who have been essentially cored and 30 cases of healthy persons wfere determined.The results showed that SOD activity is 98 3U in patients with early schisto-miasis, 486U in patients of late schistosomiasis, 617U in patients of late schistosomiasis who have been essentially cured, and 1,411U in healthy persons, respectively.There exists a significant difference between the SOD activity in normal healthy persons and in patients of late schistosomiasis (P<0.001). 测定了各期血吸虫病患者与健康人的超氧化物歧化酶活力。结果;早期血吸虫病患者(19例)为983U/ml,晚期血吸虫病患者(43例)为486U/ml,晚期血吸虫病基本治愈者(9例)为617U/ml,健康人(30名)为1,411U/ml。统计处理表明健康人与晚期血吸虫病患者的酶活力有极显著差异(P<0.001),早期血吸虫病患者与晚期血吸虫病患者的酶活力也有极显著差异(P<0.001)。对超氧北物歧化酶在血吸虫病肝硬化发病机制中的作用进行了讨论。 A new composite pattern recognition method has been introduced to solve the problem by gathering and interpreting the clinical chemistry data relating to the two cirrhosises of liver in this paper. In order to obtain maximnm amount of information for discrimination, the necessary variables were selected by using the method of additional information test and the variables finally selected were then projected onto the optimal discrimination plane.

A new composite pattern recognition method has been introduced to solve the problem by gathering and interpreting the clinical chemistry data relating to the two cirrhosises of liver in this paper. In order to obtain maximnm amount of information for discrimination, the necessary variables were selected by using the method of additional information test and the variables finally selected were then projected onto the optimal discrimination plane. The proposed method compared favorably to the Fisher desicion method and Bayes stepwise desicion and a total consistence rate of 90.9% could be reached. The results showed that pattern recognition approach was quite promising in solving clinical chemistry problems. 本文采用综合模式识别法,即将附加信息检验选变量的方法与最优判别平面投影结合起来,对血吸虫病肝硬化与门脉性肝硬化这两种临床上难以获正确诊断的疾患进行了计算机定量鉴别诊断研究。结果表明,该法优于Fisher和Bayes判别法,诊断正确率可达90.9%,展示了模式识别法应用于临床化学的广阔前景。
