近年来国内外对病毒性肝炎的研究取得较大的进展,现综述于下。病原学一、甲型肝炎(一) 甲型肝炎抗原的发现:近年来用免疫电镜从急性甲型肝炎病人的粪便中,发现一种在血清学与甲型肝炎相关的病毒样颗粒(抗原),其直径为27mμ,而在感染前的粪便则不发现,以这种颗粒为抗原可在甲型肝炎病人血清中检出相应的抗体。这些抗体可凝集粪便中的病毒样颗粒,但对HPsAg与HBcAg则不起反应。此种抗原(HAAg)感染黑猩
In recent years, domestic and foreign research on viral hepatitis has made great progress, are summarized below. Etiology First, Hepatitis A (A) The discovery of hepatitis A antigen: In recent years, immunoelectron microscopy from patients with acute hepatitis A stool, found in serology and hepatitis A virus-like particles (antigens) , The diameter of 27mμ, but not found in the feces before infection, the particles as antigen in the serum of hepatitis A patients were detected in the corresponding antibodies. These antibodies can agglutinate the virus-like particles in the stool but do not respond to HPsAg and HBcAg. This antigen (HAAg) infects chimpanzees
