    Notes: The muscularis mucosae and condensed fibrous layer of the ruminant forestomach were studied by immunohistochemistry using specific antibodies against α-smooth muscle actin (αSMA) and γ-smooth muscle actin (γSMA). The specimens were collected from the rumen, reticulum and omasum of cattle, water buffalo, sheep, goat, Barbary sheep, Japanese serow, sika deer and mouse deer.The muscularis mucosae showed immunoreactivity for both αSMA and γSMA. On the other hand, the condensed fibrous layer appearing between the propria mucosa and tela submucosa was immunoreactive only for αSMA except for that in the goat and Barbary sheep reticulum which is intermingled with γSMA immunoreactivity. The distribution of muscularis mucosae and/or condensed fibrous layer varied among the compartments of forestomach and ruminant species. In the rumen, only the condensed fibrous layer was detected. On the other hand, the omasum contained only the muscularis mucosae. In the reticulum, both were detected. The amount of the condensed fibrous layer in the reticulum varied among different species in the following order of abundance: goat 〉 Barbary sheep 〉 sika deer〉 sheep 〉 water buffalo 〉 cattle and Japanese serow. Smooth muscle cells of external muscle layer were immunoreactive for αSMA and γSMA whereas those of blood vessels and pericytes were immunoreactive only for αSMA. The present findings on the actin immunoreactivity and distribution profile of muscularis mucosae and the condensed fibrous layer provide additional knowledge to further understand the histophysiological specialization of the different compartments of the ruminant forestomach.

    Notes: The distribution and frequency of occurrence of endocrine cells in the gastrointestinal tract of the Philippine carabao (Bubalus bubalis) were studied by immunohistochemistry. Fourteen types of immunoreactive (IR) endocrine cells were revealed. Among the cell types, only chromogranin, serotonin, and bovine pancreatic polypeptide (BPP) were present in the entire gut, while the others showed restricted distribution: somatostatin, gastrin, and cholecystokinin in the abomasum and small intestine; methionine-enkephalin-Arg6-Gly7-Leu8, motilin, neurotensin, secretin, gastric inhibitory peptide, and substance P in the small intestine; peptide tyrosine tyrosine (PYY) in the large intestine: and glucagon in the whole intestinal tract. Most of the cell types showed peak density in the pyloric, duodenal, or rectal region. The highest cell type heterogeneity was observed in the duodenum. The distribution profile of the gut endocrine cells in the carabao is closely related to that in the Holstein cattle. Important findings include the occurrence of BPP-IR cells in the entire gut and the high frequency of PYY-IR cells in the large intestine.

    An Immunohistochemical Survey of Catecholamine-synthesizing Enzyme-immunoreactive Nerves and Endocrine Cells in the Bovine Pancreas (1999)

    Notes: The distribution of catecholamine-synthesizing enzyme-immunoreactive nerves and endocrine cells in the pancreas of the calf and cow was studied immunohistochemically using antisera against tyrosine hydroxylase (TH) and dopamine β-hydroxylase (DBH). TH- and DBH-immunoreactive nerve fibres were abundant both within and around the islet of Langerhans. A few TH- and DBH-immunoreactive nerve fibres were seen around the large islets characteristic of calf pancreas, but the majority of cells in the large islets, and some in islets of Langerhans, showed TH immunoreactivity. In the exocrine pancreas, both TH- and DBH-immunoreactive nerve fibres were distributed randomly among the acini, with the DBH-immunoreactive fibres being more numerous. Abundant TH- and DBH-immuno- reactive nerve fibres were seen in close association with blood vessels and in the connective tissue around the interlobular duct. Immunoreactivity for both enzymes was also observed in the nerve cell bodies and fibres of the intrapancreatic ganglia. The findings suggest an important role for catecholamines in the regulation of bovine pancreatic function.

    Notes: The occurrence and density of distribution of nerves and endocrine cells that are immunoreactive for neuropeptides in the bovine pancreas were studied by immunohistochemistry. The six neuropeptides localized were galanin (GAL), substance P (SP), methionine-enkephalin (MENK), neuropeptide Y (NPY), calcitonin gene-related peptide (CGRP) and vasoactive intestinal polypeptide (VIP). The exocrine pancreas was shown to have an appreciable number of GAL- and SP-immunoreactive nerve fibres but few fibres showing immunoreactivity for VIP and CGRP. Numerous MENK-, GAL-, SP-, and NPY-immunoreactive nerve fibres were seen in the endocrine portion of the pancreas. Nerve cell bodies in the intrapancreatic ganglia showed immunoreactivity for all of the neuropeptides except CGRP. Endocrine cells showing immunoreactivity for GAL and SP were observed in the large islets and islets of Langerhans, respectively. The present results indicate a characteristic distribution of neuropeptides in the bovine pancreas, which may regulate both exocrine and endocrine secretions of pancreas.
