Two substances that bind vitamin B(l2) are found in chickens, one in the serum and another in the proventriculus. Their molecular weights, as estimated from gel filtration on Sephadex, are approximately 113,000 and 96,000, respectively. Antibody elicitedin ratsagainst the proventriculus binder reacts against both binders.

The development of endocrine cells in the chicken proventriculus has been investigated using light- and electron-microscopy in conjunction with silver and immunocytochemical techniques. The first morphologically detectable endocrine cells were found in 5-day-old embryos by electron microscopy. From the 9th to the 13th day, endocrine cells in contact with the lumen of the organ could be detected both by electron and light (silver impregnation) microscopy. The number of open-type endocrine cells progressively decreased and the number of closed-type increased after this stage. Until the 16th day, endocrine cells were located exclusively in the luminal epithelium, but afterwards they appeared in progressively greater numbers in the compound glands. After hatching, long cytoplasmic processes could be seen in the endocrine cells. Immunoreactivities to regulatory substances appeared in the following order: serotonin (day-14), avian pancreatic polypeptide, glucagon and somatostatin (day-16), bombesin and neurotensin (day-18), and finally, met-enkephalin (day-21).

Gizzerosine, which was originally found in fish meal, is a compound that causes gizzard erosion and ulceration in chicks. The action of gizzerosine on the isolated cells of chicken proventriculus was studied in the present investigations. Gizzerosine increased intracellular cyclic adenosine-3',5'-monophosphate (cAMP) levels, reaching a plateau within 30 min. Similar maxima of cAMP level were observed in the presence of histamine or gizzerosine. However, the potency of gizzerosine was approximately 1,000-fold higher than that of histamine. The action of gizzerosine was depressed by cimetidine, a histamine H2-receptor antagonist, but not by pyrilamine, a histamine H1-receptor antagonist, indicating that gizzerosine is a very strong histamine H2-receptor agonist. The mucosal cells isolated from the proventriculus by the present procedure had both histamine H1 and H2-receptors. Gizzerosine showed a higher affinity to the cell surface histamine receptor than histamine. These results partly explain the potent activity of gizzerosine in inducing gastric acid secretion and causing gizzard erosion and ulceration in chickens.

Comparative Study
Radioimmunoassays using specific bombesin antisera revealed high concentrations of immunoreactivity in the turkey proventriculus, and negligible amounts of activity elsewhere in the gut. In immunohistochemical studies the same antisera revealed abundant endocrine-like cells in proventriculus mucosa, and isolated cells in small intestinal mucosa. In contrast to the rat, immunoreactivity was not demonstrated in nerves.
