Histological characteristics of the pancreas and spleen of Pelophylax bedriagae (Anura: Ranidae)

The histological characteristics of the spleen and pancreas of Pelophylax bedriagae were examined using light microscopy. The spleen was a highly vascular organ and composed of two functional compartments, the red pulp and the white pulp. The spleen was surrounded by connective tissue and trabeculae were not observed in the parenchyma of the spleen. The pancreas was composed of small clusters of glandular epithelial cells. Some of the cell clusters were arranged into pancreatic islets of Langerhans and corresponded to the endocrine portion. The remaining pancreatic epithelial cells were organized into clusters called acini and constituted the exocrine portion. Additionally, melanomacrophages were observed in both spleen parenchyma and pancreas parenchyma. © Biharean Biologist, Oradea, Romania, 2018
