Effect of chelerythrine on ICl(swell)
A, typical cell showing the inhibition of ICl(swell) by 10 μm chelerythrine. B, leak-subtracted mean current-voltage relationship of ICl(swell) evoked by 75 mm NaCl (•) and in the same hypotonic solution containing 10 μm chelerythrine (○). Each point is the mean ±s.e.m. of 5 cells. C, concentration-effect curve of the chelerythrine-induced inhibition of ICl(swell) at −50 mV (○) and +100 mV (•). Each point is the mean ±s.e.m. of 5 cells.
