A study was conducted to find out normal histology and histochemistry in kidneys of Aseel birds. The cortical areas were larger and lobulated, though it was challenging to differentiate the lobes due to minimal intralobular connective tissue. The medullary areas appeared as small cones, with the apex facing the uteric bud and those oriented toward the cortex. Both the cortex and medulla were encapsulated containing abundant collagen fibers. The components of the cortical regions were compactly arranged, whereas the medullary components were loosely arranged. Renal corpuscles, including juxtamedullary and cortical renal corpuscles, were observed. The juxtamedullary corpuscles were larger and located in the cortical regions near to the medulla, while the cortical renal corpuscles were smaller, loopless, and appeared toward the periphery of the cortex. Central veins were observed, surrounded by proximal convoluted tubules (PCT) and distal convoluted tubules (DCT), creating a lobular pattern similar to that of the liver. The cortical tubules, medullary tubules, and the capsules of both cortex and medulla showed a positive reaction to the combined PAS-Alcian blue stain. The cortical capsule was moderately positive for acid Phosphatase and exhibited a strong reaction to alkaline phosphatase. The brush border and basement membrane of PCT displayed a moderate reaction to both acid and alkaline phosphatases. The DCTs were moderately positive for both enzymes. Additionally, the medullary capsule showed a moderate reaction to acid phosphatase and a strong reaction to alkaline phosphatase. The thin and thick segments of the medullary collecting ducts exhibited moderate reactions to both acid and alkaline phosphatases.
