“…Histological studies have showed the abundance of nerve endings in the endocrine pancreas of various species (HONJIN, 1956;LEGG, 1968;LARSSON, 1979). Ultrastructural observations (WATARI, 1968;KOBA-YASHI and FUJITA, 1969;SHORR and BLOOM, 1970;FUJITA and KOBAYASHI, 1979;RADKE and STACH, 1986) have revealed the presence of nerve endings in contact with endocrine cells and in close vicinity to the blood vessels.…”

Summary. The ultrastructural co-localization of vasoactive intestinal polypeptide (VIP) and acetylcholine (ACh) -like cation was demonstrated in the rat endocrine pancreas. Immunoperoxidase cytochemical procedure for the detection of VIP was followed by ionic fixation of ACh by silicotungstic acid. All the VIPimmunoreactive nerve endings displayed punctiform precipitates revealing ACh-like cations in the small clear vesicles. Almost all the VIP-immunoreactive nerve terminals were in contact with endocrine A, B or D cells, but not in the close vicinity of blood vessels. Nerve endings devoid of VIP immunoreactivity but containing ACh-like cations were seen either in contact with endocrine cells or in close vicinity to blood vessels. These data suggest that VIP might modulate, concomitantly with ACh, the hormonal secretion of the endocrine pancreas, although the possibility of the neurosecretion of ACh and VIP into the blood vessels should not be excluded. ACh might also control some function of the endothelial cells of blood vessels.

“…Besides influencing the secretory activity of the islet, additional influence on the functioning of its vascular supply has been assumed (CEGRELL, 1968;LEGG, 1968;LARSSON, 1979). Ultimately, FUJITA and KOBAYASHI (1979a) proposed the pancreatic islet as a neurosecretory entity.…”

“…It is well known that the pancreaticc islets of various animals are richly supplied by autonomic nerves (COUPLAND, 1958;CEGRELL, 1968;LEGG, 1968;WA-TARI, 1968;KOBAYASHI and FUJITA, 1969;FUJITA and KOBAYASHI, 1979). In the canine pancreas, FUJITA and KOBAYASHI (1979) revealed that many of the nerve fibers in the islets form free endings filled with synaptic vesicles and peptidergic type granules in the pericapillary space.…”
