Figure 4. Effect of ion pump inhibitors on contractolation.

Figure 4

Quantitative analysis of pH induced contractolation of pII cells exposed to pH 7.4 (solid bars) or after exposure to alkaline pH for 1h (open bars). The following inhibitors were used: (A) amiloride, (B) zoniporide, (C) ouabain, (D) 3, 4,5, 6-tetrahydroxyxanthone, (E) nigericin, (F) bafilomycin A1 and (G) phloretin. Histobars represent means ± SEM of at least 3 independent determinations. Asterisk denotes significant difference from the pH 7.4 condition (set as 100%) with *p ≤ 0.05.
