Blank cells indicate that control Ringer was perfused into the corresponding bath.
All values are reported as mean ± SD.
The basal bath Δ[HCO3]-induced TEP response in control Ringer was compared to the TEP response in the presence of the inhibitor/condition; P < 0.05 is considered significant by Student’s t test.
