With subcellular fractions of animal adrenals, the authors have looked for the effect of antialdosterones on different aspects of adrenal metabolism (steroidogenesis, some enzymes of intermediary metabolism, mitochondrial respiration). Antialdosterones act on mitochondrial respiration by inducing an uncoupling effect. Nature of this uncoupling cannot yet by precised. Antialdosterones inhibit steroidogenesis with concentrations corresponding to blood concentrations observed during treatment with these compounds. This inhibition could explain the annulation of hyperaldosteronism secondary to sodium loss and kaliemic replenishment. This enhance the interest of antialdosterones over other diuretics.
作者利用动物肾上腺的亚细胞组分,研究了抗醛固酮对肾上腺代谢不同方面(类固醇生成、某些中间代谢酶、线粒体呼吸)的影响。抗醛固酮通过诱导解偶联作用影响线粒体呼吸。这种解偶联的性质尚无法明确。抗醛固酮以与这些化合物治疗期间观察到的血药浓度相对应的浓度抑制类固醇生成。这种抑制作用可以解释因钠丢失和钾补充继发的醛固酮增多症的消除。这增强了抗醛固酮相对于其他利尿剂的优势。
