本文采用放免法检测了76例健康献血员、89例不同肝病患者血清Ⅰ型前胶原（PCI）的含量。结果，急性肝炎、慢性过延性肝炎、慢性活动性肝炎、单纯性肝癌和其它肝病患者血清中PCI含量较正常人升高无显著性意义（P＞0．05），而肝硬化及肝癌合并肝硬化患者血清PCI含量显著升高（P＞0．001），表明PCI对肝硬化病人的诊断有非常重要的价值。
In this paper, 76 cases of healthy blood donors and 89 cases of different liver disease serum type Ⅰ procollagen (PCI) were detected by radioimmunoassay. Results The serum levels of PCI in patients with acute hepatitis, chronic ductile hepatitis, chronic active hepatitis, simple liver cancer and other liver diseases had no significant difference (P> 0.05), but cirrhosis and liver cancer complicated with liver Serum PCI levels were significantly higher in patients with cirrhosis (P> 0.001), indicating that PCI is of great value in the diagnosis of cirrhotic patients.
