Electron Microscopic Study of Centripetal Demyelination of Cutaneous Nerves Following Skin Granuloma
The "traumatic degeneration" of peripheral nerves has been described by Ram6n y Cajal (16) as representing the alteration of both myelin sheath and axon in the central stump of a damaged nerve, in contrast to Wallerian degeneration in the distal part of the same nerve. Distal nerve degeneration and subsequent regeneration after mechanical injuries of peripheral nerve bundles have been well-docu...

متن کاملStudies on incidence and pathology of neoplasms of reproductive system of cull laying
This study was performed to determine the incidence and anatomo-pathological aspects of the reproductive system tumors in commercial laying hens. Post mortem examination of 1041 laying hens revealed neoplasms of the ovaries and the oviduct in 52 (4.99%) cases. From these, ovarian adenocarcinoma was found in 14 cases, granulosa cell tumor in 7 cases, theca cell tumor in 1 case and Marek's dise...

During an electron microscopic study of experimental demyelination, many variations in the contour of the myelin sheath were observed in normal guinea pig sciatic nerves. These variations consisted of loops and folds of compact myelin which indented the axoplasm or protruded into the Schwann cell cytoplasm. Depending on the plane of section they were seen as isolated ovoids of myelin within axo...
