Ultrastructure of alcoholic hyaline (AH) in alcoholic hepatitis was observed to demonstrate the relationship between AH filaments and intermediate filaments (IFs). Type 1, Type 2 and Type 3 AH were noted in hepatocytes, and the filaments in these types of AH showed similar ultrastructural findings as already reported. Two different kinds of filaments were noted in the Type 2 AH. The large on showed 160 to 200 A in a diameter and the small one showed around 100 A in diameter. Of the 29 cases with alcoholic hepatitis, a new type of AH was noted in the rosette forming hepatocytes in 2 cases of alcoholic hepatitis. The filaments of this AH in rosette forming hepatocytes showed 40 to 60 A in diameter and shorter length compared with Type 2 AH. These filaments with 40 to 60 A diameter were quite different from IFs. Our results indicate that AH in alcoholic hepatitis is not induced by the simple accumulation of the IFs.

D008099 Liver A large lobed glandular organ in the abdomen of vertebrates that is responsible for detoxification, metabolism, synthesis and storage of various substances. Livers
D008854 Microscopy, Electron Microscopy using an electron beam, instead of light, to visualize the sample, thereby allowing much greater magnification. The interactions of ELECTRONS with specimens are used to provide information about the fine structure of that specimen. In TRANSMISSION ELECTRON MICROSCOPY the reactions of the electrons that are transmitted through the specimen are imaged. In SCANNING ELECTRON MICROSCOPY an electron beam falls at a non-normal angle on the specimen and the image is derived from the reactions occurring above the plane of the specimen. Electron Microscopy

D012397 Rosette Formation The in vitro formation of clusters consisting of a cell (usually a lymphocyte) surrounded by antigenic cells or antigen-bearing particles (usually erythrocytes, which may or may not be coated with antibody or antibody and complement). The rosette-forming cell may be an antibody-forming cell, a memory cell, a T-cell, a cell bearing surface cytophilic antibodies, or a monocyte possessing Fc receptors. Rosette formation can be used to identify specific populations of these cells. Immunocytoadherence,Formation, Rosette,Formations, Rosette,Immunocytoadherences,Rosette Formations
