Leuprorelin (leuprolide, D-Leu6-(des-Gly10-NH2)-LH-RH ethylamide) acetate is a super-active agonist of luteinizing hormone-releasing hormone (LH-RH). We developed once-a-month injectable microcapsules of this agonist by our novel in-water d…

The development of human uterine estrogen-dependent tumors is considered to be closely related to estrogen biosynthesis. This study examined whether or not 14 alpha-hydroxy-4-androstene-3,6,17-trione (14 alpha-OHAT), a new 4-androstene-3, 1…

Estrogen biosynthesis (aromatase activity) was investigated in human adenomyosis tissue and compared with that of the normal myometrium, endometrium, and endometrial cancer tissues. Homogenates were incubated with [1,2,6,7-3H]androstenedion…

Leuprolide acetate is a highly potent analog of luteinizing hormone-releasing hormone. We have prepared 1-month release injectable microcapsules of leuprolide acetate using a biodegradable polymer, poly (dl-lactide-co-glycolide), to treat a…

Abstract The serum prolactin (PRL) levels of 34 cases of endometriosis, 26 cases of adeno‐m‐osis, 30 cases of functional d‐smenorrhea, and 9 patients with m‐oma uteri were measured b‐ radioimmunoassa‐. The incidence of h‐perprolactinemia (>…

Abstract Nine patients with pelvic endometriosis were treated with gestrinone in a dose of 2.5 mg twice weekl‐ for 6 to 7 months. All patients became anovulator‐ with sporadic episodes of painless uterine bleeding lasting various periods of…

To understand the mechanism of action of danazol, the binding of danazol to multiple classes of intracellular steroid binding proteins was studied in the human uterine endometrium. Danazol bound to endometrial receptors for estrogen, proges…

This study was designed to clarify the effects of danazol on levels of serum luteinizing hormone (LH), follicle-stimulating hormone (FSH), prolactin, progesterone (P), and 17 beta-estradiol and endometrial steroid receptors (for estrogen [E…

Steroid receptors in endometriosis and adenomyosis were investigated to clarify their clinical significance. The receptor levels were determined by Scatchard plot analysis (4 degrees C, by dextran-coated charcoal). In the cytosols of both t…
