Figure 11. Effect of extracellular HCO3 and HOE694 on the rate of intracellular pH (pHi; proton extrusion) in crypt glands from proximal colon.

Figure 11

[A] Rate of change in pHi was examined in presence (Control) and absence (-HCO3) of extracellular HCO3. [B] Rate of change in pHi in the presence of extracellular HCO3 was examined in presence (HOE694) and absence (Control) of 1 µM HOE694. *p<0.001 - compared to respective control.
