Effects of pretreatment with different concentrations (0, 0.005, 0.01, and 0.02%) of formic acid on Ca2+ entry induced by extracellular addition of CaCl2 (0.5 mM) in the presence of thrombin (0.025 U/ml) (a), thapsigargin (1 μM) (b), or OAG (100 μM) (c). Asterisks denote significant differences (**p < 0.01) compared with the control. N = 8–9
