title: [The analysis of estrogen and pregesterone receptors in leiomyomas cell in different phases of menstrual cycle].
abstract: The aim of a study was immunocytochemical analysis of estrogen (ER) and progesterone (PgR) receptors in uterine leiomyomas cells derived from patients who underwent an operation in three different phases: in the follicular phase of the menstrual cycle (12 cases), in the luteal phase (20 cases) and in the postmenopausal age (18 cases). The examined receptors reflect the tissue sensibility to activity of sex steroid hormones and play an important role in the pathogenesis of uterine leiomyomas. Performed studies showed that expression of ER and PgR does not depend on the phase of the menstrual cycle and that it seems to be similar like in the postmenopausal stage. In all groups PgR expression was significantly higher then the expression of ER. In the group of patients in which the surgery was performed during the luteal phase of the menstrual cycle was demonstrated negatively correlation (-0.4846) between the expression of ER in relation to the expression of PgR.
