Abstract

Twenty-three fishes were used to study the structure and ultrastructure of interrenal tissue, chromaffin cells and corpuscles of Stannius of Nile tilapia. The interrenal tissue and chromaffin cells are present within the head kidney. The interrenal tissue is arranged in the form of highly convoluted cords, bordered by the lining endothelium of the adjacent sinusoids. It has no connective tissue capsule. The cytoplasm of the interrenal cells contains abundance of mitochondria, vacuoles and smooth endoplasmic reticulum, characterizing of steroid-producing tissues. Two types of chromaffin cells; noradrenaline (NA) cells and adrenaline cells (A) could be recognized by light microscope using chromaffin reaction, as well as by electron microscope they could be distinguished depending on the size and electron density of their granules. The corpuscles of Stannius are two in number and located on the dorsal aspect of the tail kidney. Each corpuscle is surrounded by thick connective tissue capsule. The parenchyma is divided into lobules, each of which is surrounded by distinct basal lamina and has a pseudo lumen. Depending on the presence of secretory granules and the relative abundance of cell organelles, three cell types could be recog...Continue Reading

Antibodies: Agglutination

Antibody-mediated agglutination is the clumping of cells in the presence of antibody, which binds multiple cells together. This enhances the clearance of pathogens. Find the latest research on antibody-mediated agglutination here.
