3H-estradiol and3H-R5020 binding in cytosols of normal and neoplastic human ovarian tissue
1983
High-affinity cytoplasmic estrogen and progesterone receptors in normal and abnormal ovarian tissues were studied. Estradiol receptor was detectable in 65% and progesterone receptor in 36% of the malignant tumors; 39% of all malignant ovarian tissues were estradiol- as well as progesterone-receptor-positive. Tumors were said to be receptor-positive when the receptors bound greater than 5 fM steroid/mg cytosol protein. No correlations were found between receptor status and histopathological diagnosis. In normal ovarian tissues collected at various phases of the menstrual cycle no changes in [3H]-estradiol and [3H]-R5020 binding could be detected. Analysis of the receptor concentration for bo…
Hysteroscopic and ultrasonographic evaluation of ulipristal acetate treatment for symptomatic myomas in premenopausal women: a prospective study
2020
Objective: This study aimed to analyze the effects of a six-month therapy with ulipristal acetate (UPA) on myoma size and endometrial thickness in premenopausal women. Material and methods: Seventy-four women undergoing conservative therapy with UPA were enrolled for this study. All women underwent transvaginal ultrasound evaluation to assess the endometrial thickness, and the number and size of myomas at the beginning and after six months. Hysteroscopy and biopsy were performed after six months, if necessary. Results: After six months of treatment, sonographic examination showed a statistically significant (p <.05) reduction of the size of the largest myoma (56.3 ± 5.1 vs. 31.7 ± 10.1 m…
