肝炎可分为三型:甲型、乙型和非甲非乙型。近年来又发现一种肝炎即δ肝炎。1977年,Rizzetto 等在意大利南部用免疫荧光法检查慢性肝病的 HBsAg 携带者时发现了一种新抗原,命名为δ因子。目前,δ因子在世界各地均有发现。我国也有δ因子的感染,但感染率是低的。许多医学工作者对δ因子进行了大量的研究,对它的理化性质、传播途径等已基本搞清。下面从几方面介绍δ因子和δ肝炎。名称及理化特性δ因子是 Rizzetto 在 HBsAg 慢性携带者的肝细胞核内和血清中发现并命名的。它是一种分子量为68000的蛋白质,耐热并耐各种化学制剂。易为碱和蛋白酶破坏。其形
Hepatitis can be divided into three types: A, B and non-B non-B type. In recent years, another hepatitis is found that hepatitis. In 1977, Rizzetto et al. Found a novel antigen when it was used to examine HBsAg carriers of chronic liver disease by immunofluorescence in southern Italy, and named it δ factor. At present, the delta factor is found all over the world. Our country also has delta factor infection, but the infection rate is low. Many medical workers have done a lot of research on the δ-factor, and have basically got a clear understanding of its physicochemical properties and transmission routes. Here are a few aspects of delta factor and delta hepatitis. Name and Physicochemical Properties The δ-factor is found and named by Rizzetto in the nuclei and serum of hepatocytes of chronic carriers of HBsAg. It is a protein with a molecular weight of 68,000, heat-resistant and resistant to various chemicals. Easy for alkali and protease damage. Its shape
