由于严重的应激反应常可造成急性肾上腺功能不足,所以对有垂体或下丘脑病变的病人常需了解其下丘脑、垂体和肾上腺皮质(HPA)的功能。肾上腺对静脉注入大剂量ACTH所产生的反应可以显示HPA的完整性,但ACTH的兴奋作用不能直接测量下丘脑或垂体的反应性。故单凭ACTH兴奋试验,就可能造成诊断错误。本文报告了四例垂体肿瘤患者,他们的短暂ACTH兴奋试验没能
Because severe stress reactions can often cause acute adrenal insufficiency, it is often necessary for patients with pituitary or hypothalamic lesions to understand their function in the hypothalamus, pituitary and adrenal cortex (HPA). Adrenal response to intravenous infusion of high doses of ACTH can show the integrity of HPA, but ACTH excitability can not directly measure the hypothalamus or pituitary reactivity. Therefore, ACTION alone excited test, it may cause diagnostic errors. This article reports four patients with pituitary tumors who failed their transient ACTH excitation test
