To study effects on pituitary-adrenocortical activity of a sustained block of angiotensin II formation, six 'drug-resistant' patients with essential hypertension were studied before and during treatment with an inhibitor of the angiotensin-converting enzyme (Captopril, SQ 14,225). The drug was given in increasing doses (100-400 mg/day) for 2 weeks whilst patients received a moderately restricted sodium intake (60-80 mmol/day). Immunoreactive ACTH, cortisol, aldosterone, plasma renin activity (PRA) and the activity of the angiotensin-converting enzyme (ACE) were measured in blood samples drawn at 0800-0900 h. Urinary excretion of cortisol and aldosterone were measured in 24-h urine collections. Further information on pituitary-adreno-cortical function was obtained by measuring serial plasma corticosteroid levels after submaximal stimulation with a synthetic ACTH preparation. ACTH and cortisol did not change an observation which does not support the hypothesis that glucocorticoid activity is influenced by a decrease in plasma angiotensin II concentrations.
为研究持续阻断血管紧张素II形成对垂体-肾上腺皮质活动的影响,对6例“耐药性”原发性高血压患者在使用血管紧张素转换酶抑制剂(卡托普利,SQ 14,225)治疗前及治疗期间进行了研究。在患者接受适度限钠饮食(60 - 80 mmol/天)的同时,以递增剂量(100 - 400 mg/天)给予该药物,持续2周。于上午0800 - 0900采集血样,测定免疫反应性促肾上腺皮质激素(ACTH)、皮质醇、醛固酮、血浆肾素活性(PRA)及血管紧张素转换酶(ACE)活性。收集24小时尿液,测定皮质醇和醛固酮的尿排泄量。通过用合成ACTH制剂进行次最大刺激后测定系列血浆皮质类固醇水平,获取有关垂体-肾上腺皮质功能的更多信息。ACTH和皮质醇未发生变化,这一观察结果不支持糖皮质激素活性受血浆血管紧张素II浓度降低影响的假说。
