Gastric surface intracellular pH response to photodamage. Values are reported for damaged (D) cells, compared with healthy near (N) and far (F) cells. Confocal reflectance (A) and SNARF-5F fluorescence images of 620–680 nm (B) and 550–600 nm (C) emission illustrate dye retention in damaged cell areas (white region). Bar = 25 μm. D: pHi was measured in control (n = 3), EIPA- (n = 4), and H2DIDS-treated (n = 5) mice 10 min after photodamage. Values represent mean ± SE. *P < 0.05 vs. control.
