一前言关于传染性肝炎之病理变化及临床征候,目前已有比较清楚的认识,病理诊断与临床诊断之符合率亦甚高。但对于传染性肝炎之分型,病变程度及转归等病理形态学方面之研究还很不够,特别是对传染性肝炎之分型问题,目前意见分歧,认识亦不一致。因之,名词繁多,概念很不明确,不易表达肝炎时肝内病变之性质及程度,致对肝炎之预后缺乏推断之依据。传染性肝炎是一个独立的疾病,故有其组织形态学的发生及发展规律,从这方面进行研 A foreword On the pathological changes of infectious hepatitis and clinical signs, there is a clear understanding of the pathological diagnosis and clinical diagnosis of the rate is also very high. However, there is still not enough research on the pathological types of infectious hepatitis, such as typing, degree of lesion and prognosis. Especially for the classification of infectious hepatitis, the opinions and disagreements are not consistent at present. Therefore, the term is manifold, the concept is not clear, not easy to express the nature and extent of intrahepatic lesions in hepatitis, resulting in the lack of prognosis of hepatitis basis for the inference. Infectious hepatitis is an independent disease, so the occurrence and development of its histomorphology, research from this area
