临床上对血吸虫病性肝硬化和肝炎后肝硬化,有时难以鉴别,以致对血吸虫病性肝硬化巨脾病人切脾预后的估计发生困难。我们在临床实践中发现血清MAO 活性在血吸虫病性肝硬化患者中大多不升高,而在肝炎后肝硬化患者中血清MAO 活性升高的百分比比较高。为此,对40例肝炎后肝硬化和46例血吸虫病性肝硬化患者的血清MAO 活性进行分析,探讨是否具有鉴别此二种肝硬化的实用意义。我院测定血清MAO 活性采用伊藤宪一法,其正常值在30单位/毫升以下。诊断肝硬化的临床指标为:(1)肝肿大或肝脾肿大,质地中等到硬;(2)腹壁静脉显露 Clinically, schistosomiasis cirrhosis and cirrhosis after hepatitis, and sometimes difficult to identify, resulting in schistosomiasis cirrhosis splenomegaly prognosis of splenectomy difficult. We found in clinical practice that serum MAO activity did not increase in most patients with schistosomiasis cirrhosis, whereas the percentage of elevated serum MAO activity was higher in post-hepatitis cirrhosis patients. To this end, 40 cases of post-hepatitis cirrhosis and 46 cases of schistosomiasis cirrhosis serum MAO activity analysis to explore whether there is the practical significance of identifying these two kinds of liver cirrhosis. Determination of serum MAO activity in our hospital using Ito constitution, its normal value of 30 units / ml below. Clinical indicators of cirrhosis diagnosis: (1) hepatomegaly or hepatosplenomegaly, texture medium to hard; (2) abdominal veins revealed
