Effect of changes in luminal pH on macula densa pHi. When luminal pH was increased from 6.8 to 8.6, there was a linear correlation between changes in pHi and extracellular pH of the macula densa. At any given extracellular pH, pHi of the macula densa at 80 mM NaCl was 0.5, higher than at 10 mM (n = 6).
