| Description | Die histologie en ultrastruktuur van die hepatopankreas van die bloukurper Oreochromis mossambicus word beskryf. ’n Dun bindweefselkapsel omring die lewer. Die hepatosietrangskikking vertoon as lobules, met die koorde van hepatosiete wat vanaf ’n sentrale vene uitradieer en met mekaar anastomaseer. Indiwiduele lewerlohules vertoon nie duidelike grense nie, maar enkele duidelike triades word wel in die lewer van O. mossambicus aangetref. Die hepatosiete bevat ’n enkele ronde kern met ’n duidelike nukleolus en die growwe endoplasmiese retikula kom in twee of meer rye om die kerne en teen die selgrense van die hepatosiete voor. Die ander sitoplasmiese organelle kom verspreid in die hepatosietsitoplasma voor. Die eksokriene pankreasselle is om die portale venes gesetel. Die kerne van hierdie selle is rond en is hasaal in die kubies- tot silindervormige selle gelee. ’n Goedontwikkelde growwe endoplasmiese retikulum — vesikulêr, tubulêr en sirkulêr in vorm — en sektretoriese granules wat apikaal in die sel gelee is, kom voor. The histology and ultrastructure of the hepatopancreas of the Mozambique tilapia O. mossambicus are described. The liver is surrounded by a thin connective tissue capsule. The hepatocyte arrangement shows as lobules, with the hepatocyte cords that radiate and anastomose from a central vein. Borders of individual liver lobules do not show clearly, as do the few triads found in the liver of O. mossambicus. Each hepatocyte contains a single round nucleus with a prominent nucleolus. The rough endoplasmic reticulum appears in two or more rows around the nuclei and in close proximity to the plastnalemma of the hepatocytes. The remaining cytoplasmic organelles are scattered throughout the hepatocyte cytoplasm. The exocrine pancreas cells are centred around the portal veins. The nuclei of these cells are spherical and hasally situated in the cubiform to cylindriform cells. Well developed rough endoplasmic reticula - vesicular, tubular and circular in appearance - as well as secretory granules, apically situated in the cells, are present. | |
