Dystrophic axons (DAs) in rat gracile nuclei were largely classified into two types. One type had a focal swelling measuring about 2-8 microns in diameter, and contained greatly increased numbers of various cellular organelles. Numerous reaction products of acid phosphatase (ACPase) cytochemistry were deposited in the cytoplasmic matrix and the multilaminated bodies. The second type ranged from 8 microns to 50 microns in diameter, and was characterized by the presence of a large number of fine tubular structures in the cytoplasm. Only a few reaction products of ACPase cytochemistry were localized in the small vesicular structures. The functional role of ACPase in the degradation and accumulation of cellular organelles in DAs is discussed.

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
