Biopsy materials from human liver in cases of serum hepatitis were studied in thin sections with the aid of electron microscopy and x-ray scanning microanalysis or electron probe microanalysis. In all the cases of serum hepatitis, glycogen granules appear always all over the cytoplasm of hepatic parenchymal cells, except for cases in which the cytoplasm is occupied by a large number of hemosiderin granules or ferritin particles. The glycogen granules are characteristically organized into 400 to 700 A rosettes composed of smaller granules approximately 200 A in diameter. The lipofuscin granules are often located in the vicinity of a cell boundary, close to a bile capillary. Dense particles 300 to 350 A in diameter, without being surrounded by a limiting membrane, are found in the cytoplasm of the hepatic parenchymal cell and in the dark inclusion body appearing in the intercellular space in almost all the cases of serum hepatitis, suggesting that they may represent the viral particles of serum hepatitis.
