Effects of calcium removal on bullfrog gastric mucosal

FORTE, JOHN G., AND ALAN H. NAUSS. Effects of calcium removal on bullfrog gastric mucosa. Am. J. PhysioL 205(4): 631637* I g63.-Removal of calcium from isolated bullfrog gastric mucosae by serial washings in calcium-free solutions or by the addition of EDTA or citrate caused a fall in transmucosal potential difference, a rise in the mucosal conductance, and an apparent decrease in the rate of a...

Quantitative aspect of acid secretion response of isolated bullfrog gastric mucosa preparation: effect of secretagogues and inhibitors.

Concentration and localization of calcium in frog gastric mucosa.

SCHWARTZ, MANUEL, HERBERT K. KASHIWA, AHREN JACOBSON, AND WARREN S. REHM. Concentration and locali<ation of calcium in frog gastric mucosa. Am. J. Physiol. 2 12(2) : 241246. I g67.-Removal of Ca $3from the solutions bathing the frog gastric mucosa results in an initial increase in resistance (first phase) and a decrease in the H+ secretory rate of about 4oy0. These effects are followed by a pro...

Restitution of the bullfrog gastric mucosa is dependent on a DIDS-inhibitable pathway not related to HCO3- ion transport.

This study was conducted to determine the contribution of ion transport to restitution after injury in the gastric mucosa. For this, intact sheets of stomach from the bullfrog, Rana catesbeiana, were mounted in Ussing chambers. Restitution was evaluated in the presence or absence of ion transport inhibitors amiloride, DIDS, and bumetanide to block Na(+)/H(+) exchange, Cl(-)/HCO(3)(-) exchange a...

Effects of two alfalfa preparations with different particle sizes on the gastric mucosa in weanlings: alfalfa chaff versus alfalfa pellets

BACKGROUND Feeding alfalfa hay is often recommended for its buffering components, like protein and calcium, to prevent lesions of the gastric mucosa in horses. Until now, there has been no information regarding the influence of alfalfa particle size on the gastric mucosa. The aim of this study was to investigate the effects of feeding two alfalfa preparations with different particle sizes (alfa...
