These pro - inflammatory responses were inhibited by two types of Ca ( 2 + ) blockers , bis - ( o - aminophenoxy ) ethane - N , N , N ' , N ' - tetra - acetic acid acetoxymethyl ester ( BAPTA - AM ) and nifedipine , thus , indicating that the effects are triggered by initial increase in the intracellular concentration of free Ca ( 2 + ) ( [ Ca ( 2 + ) ] i ) .
