| In order to determine the histological and histochemical structure of the urinary system, this study was carried out in 10 female and 10 male twenty-week-old healthy native partridges. The birds were anesthetized by chloroform inhalation and euthanized. After dissection, the position of kidneys and ureters with related structures studied. Tissue samples from cranial, middle and caudal portions of each kidney and ureter fixed in 15% neutral buffered formalin. Sections stained with H&E for histological observation and special stainings: Masson’s trichrome, Verhoeff’s, PAS, Alcian blue, and Gomori’s for histochemical investigation. Two nephron types present in kidney of birds. Renal capsule was made up of all the connective tissue fibers. Alcian blue and PAS-positive reaction found in the proximal convoluted tubules, collecting tubules and collecting ducts. The primary branches of ureter composed of tunica mucosa, submucosa, muscularis and serosa, whereas the secondary branches was only consisted of epithelium and connective tissue fibers. In all different regions of ureter, lymphatic tissues were not observed in the lamina propria. Histology of kidney and ureter showed no significant sex-based differences. Also, the histological structures of the kidney showed no significant differences among different divisions of the left and right kidneys. The microvilli and mucosal folds were more identified in the proximal region than those of the other regions of the organ. The thickness of tunica muscularis increased from the proximal to the distal region of the ureter. Unusual findings of the ureter in Alectoris chukar were the presence of isometric longitudinal folds, and muscularis mucosa. | ||
