Morphological characteristics of chicken liver influenced by immunostimulants

The paper studies the influence of Raspol polysaccharide and fosprenil on chicken liver microstructure during vaccination against avian infectious bronchitis. response to integrated effects vaccine immunostimulants this period caused weakly expressed edema in perisinusoid spaces marked activation reticuloendothelium cells represented by increase Kupffer’s cells. On 28th day after vaccination, all hepatocytes were distinguished uniformity magnitude shape. They lacked evidence prior dystrophic changes. Most actively synthesizing as indicated dark oxyphilous color cytoplasm. RES walls sinus capillaries still numerous, with a large volume cytoplasm nucleus. previous refer phenomenon form cluster lymphoid perivascular regions triad area, mucoid degeneration vascular disappeared. lumens biliary passage well observed, especially chickens first group. chicks control group revealed local disorders absence signs metabolic disorders. Organ parenchyma retained structural moderate biosynthetic activity
