The effects of dibutyryl cyclic AMP, noradrenaline and theophylline have been studied on the uptake of 45Ca by pinched-off presynaptic nerve terminals (synaptosomes) from rat brain. All three substances enhanced the high potassium (71 mM) stimulated 45Ca uptake. In the presence of normal potassium (5 mM) neither dibutyryl cyclic AMP nor theophylline changed(More)
