Histomorphometrical and histochemical study of the pancreas on the local dogs (Canis lupus familiaris)
In the current study, ten adult healthy local dogs of both sexes were used to perform histomorphometrical study on their pancreases. The dog pancreas had an inverted V-shape consisting of left and right lobes joined by a body. The pancreas possesses both exocrine and endocrine parts. The exocrine po...

| description | In the current study, ten adult healthy local dogs of both sexes were used to perform histomorphometrical study on their pancreases. The dog pancreas had an inverted V-shape consisting of left and right lobes joined by a body. The pancreas possesses both exocrine and endocrine parts. The exocrine portion was composed of numerous acini and fewer tubules as well as the duct system. The number, total diameter and cellular height of acini were significantly abundant, larger and taller in the right lobe compared those of the body and left lobe. Furthermore, the number and total diameter of large pancreatic islets were significantly abundant and larger in the left lobe despite with those of the body and right lobe. This result leads to consider the right lobe was a target region for enzymatic secretion, while the left lobe has a specific function for hormonal secretion. According to available literature, no such result and thus conclusion had been reported on dog pancreas previously. In all parts of the pancreas and with aldehyde fuchsin stain, only the large pancreatic islets contained α-, β-, δ-cells as well as non-staining cells. Only, the β-cells occurred as single cells between the pancreatic acini or even within the connective tissue septa. These single cells were more numerous in the left lobe, but they were infrequently located in the body and right lobe. |
