Antigen trapping in the reticuloendothelial system of Schizothorax niger Haeckel

Abstract

By injecting the colloidal carbon particles, the mononuclear phagocyte system in Schizothorax niger was studied in vivo. As per results the major organs of carbon particle localization in Schizothorax niger after studying histology of organs from 2 hours to day 8 were kidney, spleen, thymus and heart. Spleen was seen with highest density of carbon particles followed by the kidney. The medulla of the thymus was seen first with antigen trapping ability followed by the cortex after day 4. The ventricular endocardial cells of heart were seen as Immunocompetent. Uptake of carbon particles by the monocytes was seen upto day 2.
