1 Hypothalamo-pituitary-adrenocortical (HPA) activity was suppressed in rats treated with betamethasone. 2 Recovery of normal HPA function occurred after corticosteroid withdrawl. 3 Although corticotrophin release was rapidly restored to its basal rate there was a delay in the return of the normal adrenocorticotrophic response to stress and normal adrenocortical function was evident only after the plasma adrenocorticotrophic hormone had reached 'supra-normal' levels. 4 The physiological significance and possible clinical relevance of the results are discussed.
1 用倍他米松治疗的大鼠下丘脑-垂体-肾上腺皮质(HPA)活性受到抑制。2 停用皮质类固醇后,HPA功能恢复正常。3 尽管促肾上腺皮质激素释放迅速恢复到基础水平,但对应激的正常促肾上腺皮质反应恢复存在延迟,只有在血浆促肾上腺皮质激素达到“超正常”水平后,正常肾上腺皮质功能才明显。4 讨论了这些结果的生理意义和可能的临床相关性。
