- Abstract
The corticotrophin-releasing activity of stalk-median eminence (SME) extract was studied using incubated quarters of anterior pituitary glands obtained from rats with long-term anterolateral deafferentation or complete surgical lesion of the medial basal hypothalamus, as well as with the lesion of the paraventricular nuclei. These hypothalamic interventions are known to cause a complete or partial but significant deficiency in hypothalamic corticotrophin-releasing factor (CRF) release, however, such lesions failed to alter the sensitivity of the ACTH response from incubated pituitary segments towards the SME extract. These results suggest that the specific responsiveness of adenohypophysial corticotrophs is maintained when hypothalamic CRF supply is decreased for a long period of time. Copyright © 1983 S.
