we demonstrated previously that na+/h+ exchange activity was enhanced in rat parotid acinar cells following muscarinic ( carbachol ) or alpha-adrenergic ( epinephrine ) stimulation and that this activation of the exchanger was preserved in plasma membrane vesicles prepared from these cells ( manganel , m. , and turner , r. j . ( 1989 ) j. membr . biol . 111 , 191-198 ) .
