Figure 2. Effect of Ang II on the pH_i recovery from intracellular acidosis.

Representative pH_i recordings obtained during two consecutive 15 mm NH₄Cl pulses. ○, first pulse; •, second pulse performed after either 5 min (A) or 20 min (B) of exposure of cells to Ang II. The 5 min incubation period with Ang II failed to affect pH_i recovery (n = 4) whereas a 20 min exposure to Ang II significantly accelerated recovery from acidosis (n = 5).
