| Abstract | ||||
| This study aimed to investigate and compare the histochemical structure of pancreatic tissue in healthy adult Collared Doves (Streptopelia decaocto) and Buzzards (Beuteo beuteo vulpinus) divided by their diet habitats. The birds were anesthetized with Ketamine, the pancreas was dissected, fixed with paraformaldehyde 10%, processed for paraffin embedding and histological sections were stained with hematoxylin and eosin, Masson trichrome and Gomori stain. The buzzards' pancreas is composed of capsule and parenchyma, which contains acini, ducts, along with blood vessels surrounded by connective tissue. Among the pancreatic acini, tiny irregular islets, single endocrine cells, and the intercalated duct could be identified. Magnified sections reveal the tiny irregular islets, Langerhans islet, interlobular connective tissue, and intercalated duct. Endocrine and exocrine parts, parenchyma, interlobular and interacinar connective tissue, alpha and beta cells, and blood capillaries under high magnification. The dove's pancreas (Streptopelia decaocto) was tiny and extended between the duodenum. Dove pancreas histology exhibited Interlobular connective tissue septa, interlobular duct, pancreatic islets, and acini containing zygomatic cells were found in dove pancreases. Myoepithelial cells, massive alpha and beta cell islets, and a connective tissue capsule surround the main duct and lumen. In conclusion, the histological structures of the pancreas in both birds were largely similar, with minor differences observed in the width of the pancreatic ducts and the number of alpha and beta islets. The histochemical study revealed variations in the intensity of different pancreatic components. | ||||
