Acinar Cell Types in the Pancreas of Frugivorous Bat Rousettus leschenaulti (Desmarest)

Abstract

The pancreas is an unique exocrine and endocrine gland secrets both enzymes and hormones respectively.The pancreas of frugivorous bat Rousettus leschenaulti was consisting of head neck and bilobed tail or uncinate process. The length of uncinate ranges between 1.0 to 1.7 cm. Histologically the exocrine part of pancreas of Rousettus leschenaulti before and after foraging shows different acinar cell types. During before foraging stage the pyramid shaped cells with spherical nucleus are the Active acinar cells. The size of the nuclui measures between 3.57 µ to 4.25 µ. while bats with after foraging stage shows cuboidal shaped with oval nucleus with more chromatin and zymogen granules shows Resting acinar cells.The size of the nuclei ranges between  2.67 µ to 3.92 µ in diameter. The pacinian corpuscles were observed at after feeding stage and were not found at before feeding stage.
