Fig. 2. Effects of the Nigella arvensis (NA) extract on Cl^- secretion. (A) Epithelia were incubated in 102 mmoll^-1 NaCl-Ringer solutions on both apical (Ap) and basolateral (B1) sides; N-methyl-D-glucamine chloride (NMDGCl)-Ringer was then added apically 30 min before the NA extract (250 µll^-1) was administrated basolaterally. 50 µmoll^-1 amiloride (Ami) was added at the end of the experiment. (B) Same experimental conditions as in A, but NMDG₂SO₄-Ringer was applied apically 30 min before the NA extract was added. At the end of the experiment, basolateral Cl^- was replaced by SO₄^2-.
