title: Proliferative activity and level of steroid hormone receptors in the myometrium and myoma nodes in different phases of menstrual cycle.
abstract: We compared proliferative activity and levels of steroid receptors in the myometrium and myoma nodes in patients with uterine myoma in different phases of menstrual cycle. Maximum proliferative activity was observed at the periphery of myoma nodes in the the secretory phase of the cycle. The content of progesterone receptors at the periphery and in the center of myoma nodes was lower in the proliferative phase of the cycle than in the secretory phase. Steroid regulation of proliferative activity in the myoma nodes in the the secretory phase through modulation of the content of progesterone receptors is hypothesized.
