Summary
A biolin-labeled DNA probe specific for hepatitis B virus (HBV) nucleotide sequences was hybridized in situ to liver tissue of 129 cases with liver disease. It was found that HBV DNA was predominantly visualized in cytoplasm of hepatocytes in three patterns: cytoplasmic compact, discrete and inclusion pattern. Its distribution in parenchyma in the sections of specimens may be defined as lobular, focal and spotty. The detection of intrahepatic HBV DNA depended on two factors, at least in the present study: 1) liver disease activity; chronic active hepatitis (CAH) group had a significant higher prevalence (81%) as compared to cirrhosis, chronic lobular hepatitis (CLH), acute hepatitis and hepatocellular carcinoma (HCC) groups; 2) HBV infection state: HBV DNA was more easily detected in HBeAg positive or intrahepatic HBcAg positive patients than in single HEsAg positive or anti-HBc cases. The findings that hepatocytes expressing HBV DNA, particularly in focal distribution, were closely related to hepatic necrosis sites suggested that HBV replication might occur in conjunction with hepatic necrosis.
