Effects of benidipine with or without LPC on ACh-induced increases in [Ca2+]
. Endothelial cells were treated as described for Figure 3. Benidipine (1 or 10 nmol/L) or DMSO was simultaneously added with LPC or ethanol. Changes in ACh-induced increases in calcium are expressed as percentage fluorescence value of ACh-induced increases in calcium prior to LPC or ethanol treatment. Each value represents the mean ± S.E. of 7 cells. *P < 0.05, **P < 0.01, ***P < 0.001 compared between indicated groups.
