Effect of 24, 25-dihydroxycholecalciferol on the placental immunoreactive calcitonin.
: OBJECTIVES: Calcitonin (CT) has a regulative function in calcium (Ca) transfer from mother to the fetus. There are indications that cholecalciferol can play a role in this process. With this background, the effect of 24, 25-dihydroxycholecalciferol (24, 25-DHC) on immunoreactive CT by human placenta at term was studied in vitro. METHO.....
