[Peculiarities of theophylline and prolactin interaction and calcium fluctuation from intracellular stores of porcine oocytes in the presence of estradiol].
Using a fluorescent dye chlortetracycline, a study was made of the effect of estradiol on the interaction of theophylline and prolactin in the course of Ca2+ exit from intracellular stores of pig oocytes, isolated from ovaries at the stage of follicle growth. It is shown that in the presence of estradiol, prolactin does not stimulate Ca2+ exit from intracellular stores of pig oocytes. The action of theophylline similarly does not stimulate Ca2+ exit. Unlike, a joint effect of theophylline and prolactin on pig oocytes in the presence estradiol stimulated Ca2+ exit from intracellular stores of pig oocytes. These data demonstrated the influence of estradiol on theophylline and prolactin stimulated Ca2+ exit from intracellular stores of pig oocytes.
