Cell survival in rabbit gastric glands: effect of extracellular pH, osmolarity, and anoxia.


Although backdiffusion of luminal acid is regarded as a common mechanism of gastric injury, the extracellular pH (pHo) at which cells are irreversibly injured is not well defined. Exclusion of the fluorescent dye propidium iodide was used to estimate cell survival in rabbit gastric glands incubated in buffers of pHo 8.0-2.0. Mean survival (+/- SE) for n = 6… (More)
