[Changes in the content of prolactin and somatotropin and the level of their binding with cells in the growing antral follicles of cows].
The hormone concentrations in the follicular fluid rise along with an increase in follicular diameter whereas the level of their binding to cells declines. The findings suggest that two basic parameters characterizing the degree of prolactin and somatotropin actions on granulosa cells develop in different directions in the course of antral follicle maturation.
