Effect of aldosterone on the content of serotonin, cAMP, and the activity of 5-hydroxytryptophane decarboxylase was studied in different rat tissues (hypothalamus, kidneys, tibial muscles) in norm and following the lesion of sciatic nerve in nonadrenalectomized and adrenalectomized animals, that is in conditions of severe deficiency of endogenous aldosterone. In nonadrenalectomized rats, exogenous aldosterone exerted either very little effect or no effect on the tissues metabolism of serotonin and cAMP. Aldosterone induced changes in the content of considered substances against the background of adrenalectomy in animals with intact sciatic nerve. These changes were observed usually only in hypothalamus and kidneys and reached their peak 60 or 90 min following the aldosterone administration. The changes in serotonin and cAMP tissues metabolism under the chronic stimulation of nervous system periphery with aldosterone may be an additional factor which enables further aggravation of trophic state of tissues and organs and alteration of their sensitivity to hormones, in particular, aldosterone.
研究了醛固酮对正常及坐骨神经损伤的未切除肾上腺和切除肾上腺动物(即内源性醛固酮严重缺乏的情况下)不同大鼠组织(下丘脑、肾脏、胫骨肌肉)中血清素、环磷酸腺苷(cAMP)含量及5-羟色氨酸脱羧酶活性的影响。在未切除肾上腺的大鼠中,外源性醛固酮对血清素和cAMP的组织代谢影响甚微或无影响。在坐骨神经完整的动物中,醛固酮在肾上腺切除的背景下引起了所研究物质含量的变化。这些变化通常仅在丘脑和肾脏中观察到,并在给予醛固酮后60或90分钟达到峰值。在醛固酮对神经系统外周进行慢性刺激的情况下,血清素和cAMP组织代谢的变化可能是一个额外因素,它会进一步加剧组织和器官的营养状态恶化,并改变它们对激素(特别是醛固酮)的敏感性。
