we examined the effects of the divalent cations ca2+ and mg2+ on inositol phosphate accumulation in bovine parathyroid cells prelabelled with [ 3h ] inositol to determine whether the high extracellular ca2+ and mg2+-evoked transients in cytosolic ca2+ in these cells might result from increases in cellular ip3 levels .
