Hepatitis B core antigen (HBc Ag) and hepatitis B surface antigen (HBs Ag) were detected in the liver tissue of a patient with chronic aggressive hepatitis by the immunofluorescent complement technique. The presence of anti-HBc was examined by the same method in 67 human sera previously tested for HBs Ag, anti-HBs and s-GPT levels. HBc Ag was localized mainly in the nucleus and sometimes in the cytoplasm of the hepatic cells. HBs Ag was found only in the cytoplasm. The focal area of HBc Ag positive hepatic cells seemed to correspond to the HBs Ag positive cells. Double staining demonstrated the simultaneous presence of HBs Ag and HBc Ag in individual cells. Anti-HBc positive serum was found in 46 (68.7%) cases. Forty-eight (71.6%) indicated a combination of HBs Ag and anti-HBc.
