[Localization of HBsAg, immunoglobulins, fibrin and C3 in the liver by direct immunoflourescence].
Liver biopsies of sixty patients with different forms of hepatitis and ten control subjects without hepatic disorders were examined by means of direct immunofluorescent methods for the HBsAg, immunoglobulins, fibrin and C3. The presence of fluorescent particles of HBsAg in the cytoplasm of hepatocytes were correlated with the presence of HBsAg in the serum. The fluorescence did not seem specific of histological stage of hepatitis. Immunoglobulins and fibrin were often demonstrated in hepatic sinusoids, especially in chronic aggressive hepatitis. In contrast, C3 is rarely observed.
