Adrenal steroidogenesis has been studied in vivo in normal men and women. Serum levels of nine steroids on the biosynthetic pathway (the delta 5 3-beta-hydroxysteroids, pregnenolone (Pe), 17 alpha-hydroxypregnenolone (17Pe), dehydroepiandrosterone (DHEA), androstenediol (Adiol), and their delta 4 3-keto counterparts, progesterone (Po), 17 alpha-hydroxyprogesterone (17Po), androstenedione (Adione), and testosterone (T)) as well as cortisol were measured during adrenal suppression and stimulation. This study demonstrates a marked heterogeneity in adrenal steroid responses between different subjects in the normal population. Thus, in three subjects ACTH stimulation from a dexamethasone-suppressed state resulted in a far greater increment of 17Po than in the other nineteen normal subjects. These three individuals (designated Type 2 responders) may have a partial deficiency of 21-hydroxylase activity. In the remaining nineteen subjects (designated as Type 1 responders) the women had a greater increment of Adiol (P less than 0.05) and a lower increment of Po (P less than 0.01) than the men, suggesting that adrenal 3-beta-hydroxysteroid dehydrogenase/isomerase activity may be slightly lower in women than men.
已经在正常男性和女性体内对肾上腺类固醇生成进行了研究。在肾上腺抑制和刺激期间,测量了生物合成途径上九种类固醇的血清水平(δ5 3-β-羟基类固醇,孕烯醇酮(Pe)、17α-羟基孕烯醇酮(17Pe)、脱氢表雄酮(DHEA)、雄烯二醇(Adiol),以及它们的δ4 3-酮对应物,孕酮(Po)、17α-羟基孕酮(17Po)、雄烯二酮(Adione)和睾酮(T))以及皮质醇。这项研究表明,正常人群中不同受试者的肾上腺类固醇反应存在明显的异质性。因此,在三名受试者中,从地塞米松抑制状态进行促肾上腺皮质激素(ACTH)刺激导致17Po的增量远大于其他十九名正常受试者。这三名个体(称为2型反应者)可能存在21-羟化酶活性的部分缺陷。在其余十九名受试者(称为1型反应者)中,女性的Adiol增量更大(P<0.05),Po增量更低(P<0.01),这表明女性的肾上腺3-β-羟基类固醇脱氢酶/异构酶活性可能略低于男性。
