Regulation of hydrochloride secretion in the eel anguilla japonica stomach

Zoological Science (Tokyo) 3(3): 429-436
Regulation of hydrochloride secretion in the eel anguilla japonica stomach
Simultaneous measurements of H+ secretion rate (JH), transepithelial potential difference (PD), short-circuit (Isc) and tissue resistance (Rt) were performed in the isolated stripped stomach of the eel to examine effects of three secretagogues, pentagastrin, acetylcholine (Ach) and histamine. Pentagastrin did not affect any of these parameters, but both Ach and histamine stimulated the JH. However, effects of these two secretagogues were different, especially in the response of Isc and Rt: Ach enhanced Cl--sensitive Isc and diminished Rt, whereas histamine had no significant effects on these two parameters. These results suggest that the latter two secretagogues do not act through a common pathway in stimulating Isc and reducing Rt. Independent actions of Ach and histamine were more clearly demonstrated by using atropine, an Ach antagonist, and metiamide, a histamine antagonist. In the presence of metiamide, Ach enhanced JH, Isc and PD, accompanied by reduction in Rt, indicating that Ach acts independently from histamine action. By comparing these results with those reported in frog or mammalian stomach, a possible role of Ach in regulating HCl secretion in the eel stomach is discussed.
