<p>To analyze the appearance of three forms of hepatitis B antigen-associated particles (HB Ag particles) and antigen-antibody (Ag-Ab) complexes in the sera of patients with various liver diseases, electron microscopic observations with the combinations of a variety of immunological assays were made at first on the HB Ag and Ab mixed in vitro in various ratios, and then on the samples from the sera of each patient. The number of patients observed were 64 in total, which consisted of various types of hepatitis, Hodgkin's disease, Down's syndrome and an asymptomatic carrier. For the detection of HB Ag-Ab complexes a modified method of ALMEIDA was used, and for the isolation of large HB Ag particles (Dane particles) DANE'S method was employed. Electron microscopy proved to be a useful method for detecting HB Ag and the Ag.Ab complexes when the ratio of HB Ag to Ab was in the equivalence. Large aggregates of Ag-Ab complexes were frequently observed in the attacks of acute hepatitis and the recrudescences-of chronic aggressive hepatitis. The aggregates were also observed in fulminant hepatitis but the ratio of HB Ag to Ab was different from each other among 3 cases examined. The large HB Ag particles were not observed in more than half of the cases in the attacks of acute hepatitis, but appeared in the major. ity of cases in chronic aggressive hepatitis, even massively during the period with transiently elevated levels of serum glutamic pyruvic transaminase. A few large particles were also found in sera of an asymptomatic carrier, Hodgkin's disease, and Down's syndrome.</p>
