Abstract:

Microscopic and histoenzymic studies were conducted on the lymphoid tissue in pharyngeal tonsil of six male crossbred goats of six months of age. The tonsil was lined by pseudostratified ciliated columnar epithelium which was transformed at places into follicle-associated epithelium (FAE). Propria-submucosa comprised of a central axis of loosely arranged connective tissue with dense aggregates of lymphoid tissue in the form of cryptolymphatic units and tonsillar nodules, fine blood capillaries and few nerve fibres folded around it. The average diameter of lymphoid nodules was 921.67±8.72µm and the lymphocyte count per nodule was 32233.23±324.24. The average number of lymphatic nodules counted per field under low power magnification of microscope was 2.5±0.43 and the internodular distance was 29.83±1.40µm. The fibroblastic reticulum cell (FRC) in lamina propria were acid-phosphatase (ACP) and alkaline phosphate (ALP) positive and gave a reticular reaction in the parafollicular and internodular regions and linear reaction in the capsule of lymphatic nodules. The FRC around the lymphatic nodules and internodular regions, the follicular dendritic cells (FDC) in dome, corona and FAE and the B-cell area lymphocytes showed ATPase activity. Alpha naphthyl acetate esterase (ANAE) activity was seen in the cytoplasm of T-lymphocytes and macrophages in the intercellular spaces between FAE and the basement membrane, internodular area and mantle zone of the lymphoid nodules.
