Abstract

The surface (HBsAg) and core (HBcAg) antigens of hepatitis B virus (HBV) have been searched by optic microscopy in the liver specimens from patients hospitalized for various conditions and from 38 HGsAg chronic carriers. The study was done blindly using Shikata et al.'s orcein staining on fixed and frozen material and direct immunoperoxidase on frozen material with antisera specific for surface (anti-HBs) and core (anti-HBc) antigens of HBV. No liver staining could be found in the 98 HBsAg seronegative patients. Among the 28 HBsAg seropositive patients, only 3 showed positive staining: 1 patient with acute viral hepatitis showed nuclear staining with anti-HBc; 2 patients with postnecrotic cirrhosis showed cytoplasmic staining with anti-HBs and/or orcein, and one of them also showed nuclear staining with anti-HBc. In contrast, among the 38 chronic carriers, 25 showed positive cytoplasmic staining with anti-HBs and/or orcein, while one of them (with chronic aggressive hepatitis) also showed nuclear staining with anti-HBc. Anti-HBs and orcein staining are equally sensitive and specific for the detection of HBsAg in hepatocytes; discrepant results can be attributed to sampling error of distribution of HBsAg in small liver fragments.
