作者对213例急性及慢性非甲非乙型肝炎(NANBH)患者检测了血清中丙型肝炎病毒抗体(抗-HCV)。病人和方法对1981年1月至1989年1月8年间的急、慢性 NANBH 患者作了研究。检测急性期患者血清,并在5～6个月后复查。急性患者均有明显临床症状与体征,谷丙转氨酶(ALT)值峰>1000IU/ml,胆红素>3mg/dl,乙型肝炎有关病毒学标记均阴性。慢性 NANBH诊断为 HBsAg 阴性至少2次,ALT 超过正常2 The authors tested serum hepatitis C virus antibodies (anti-HCV) in 213 patients with acute and chronic non-A, non-B hepatitis (NANBH). Patients and Methods Acute and chronic NANBH patients from January 1981 to January 1989 were studied. Detection of acute patients serum, and in 5 to 6 months after the review. Acute patients have obvious clinical symptoms and signs, alanine aminotransferase (ALT) peak value> 1000IU / ml, bilirubin> 3mg / dl, hepatitis B virological markers were negative. Chronic NANBH is diagnosed as having HBsAg negative at least 2 times and ALT exceeding normal 2
