Среднее снижение концентрации эстрадиола составило 49,8% и было выражено в большей степени у пробандов с индексом Кетле &gt; 30 или с содержанием жира в теле свыше 40 кг, чем у женщин с меньшей величиной этих параметров. Концентрация гонадотропинов (фолликулостимулирующего и лютеинизирующего гормонов) в крови при приеме препарата "Фемара" существенно не изменялась. Обсуждаются возможные механизмы эндокринных изменений и факторы, определяющие чувствительность к ингибиторам ароматазы in vivo в менопаузе.</p></abstract><trans-abstract xml:lang="en"><p>Effect of Femar, an imidasole inhibitor of aromatase, in a daily dose of 0.25 mg orally for 2 days, on blood estradiol is assessed in 16 menopausal women. The mean decrease of estradiol was 49.8%; this decrease was more pronounced in probands with Ketle ’s index of &gt;30 or more than 40 kg of fat in the body in comparison with women with lower values. Gonadotropin (FSH and LH) concentrations in the blood were not much changed by femar. Possible mechanisms of endocrine changes and factors determining the sensitivity to aromatase inhibitors in vivo during the menopause are discussed.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>эстроген</kwd><kwd>постменопауза</kwd><kwd>гонадотропины</kwd></kwd-group><kwd-group xml:lang="en"><kwd>estrogen</kwd><kwd>postmenopause</kwd><kwd>gonadotropins</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Берштейн Л.
