Id: 13459 Author: Hayes, Thomas G Title: Structure of the ellipsoid sheath in the spleen of the armadillo (Dasypus novemcinctus). A light and electron microscopic study ..- Source: s.l; s.n; oct. 1970. 17 p. ilus. Abstract: The spleen of the armadillo is invested by a capsule composed predominantly of smooth muscle. Inward extensions from the capsule contribute to an extensive system of trabeculae of the non-vascular type. The white pulp presents series of venous sinsuses. The capillary segment of the penicillar artery is invested by an ellipsoid sheath. The spleen of the armadillo may be included in the class of mammalian spleens characterized as sinusal in nature and possessing ellipsoid sheaths. Electron micrographs of thin sections of the sheathed capillaries demonstrate a high-type of endothelium. A characteristic feature of this endothelium is the presence of a distinct intracytoplasmic fibrous component. The reticular cells comprising the sheath proper exhibit various sized vacuoles and inclusion bodies suggestive of their potentially phagocytic nature. In both light and electron microscopy, venous sinuses lie in close proximity to the paripheral cells of the ellipsoid sheaths. Within the wall of the venous sinuses, patent openings are apparent between the lining cells. If such an arrangement exists in the functional state of the organ, it could provide for an additional means of exposure of both plasma and cellular elements to the adjacent phagocytic cells of the sheath proper.(AU).

Id: 13307 Author: Date, Anand; Thomas, Alexander; Mathai, R; Johny, K. V Title: Glomerular pathology in leprosy. An electron microscopic study ..- Source: s.l; s.n; mar. 1977. 7 p. ilus, tab. Abstract: Electron microscopic examination of renal biopsies from 19 patients with leprosy who had edema, proteinuria, or hematuria showed a proliferative glomerulonephritis in 12, amyloidosis in 2, and no lesion in 5. The proliferative glomerulonephritis was of different patterns: diffuse with or without exudation, focal, or mesangial. Subendothelial and/or subepithelial deposits were seen in five biopsies. Of the patients with glomerulonephritis, 3 had a reduced total serum complement level, 5 had erythema nodosum leprosum, 5 had evidence of recent streptococcal infection, and 2 had microfilariae in the peripheral blood. The significance of these findings is discussed.(AU).
