title: A noninvasive functional lesion of the hypothalamo-pituitary axis for the study of growth hormone-releasing factor.
abstract: Rats were passively immunized with an antiserum against somatostatin and a monoclonal antibody against rat hypothalamic growth hormone-releasing factor (rGRF-mAb) which does not recognize the biologically active 1-40 amino acid fragment of hpGRF-44 (hpGRF-40). Using this paradigm we have observed that the pituitary possesses a resilient capacity to release growth hormone (GH) following repeated injections of hpGRF-40 and that this response follows a dose-dependent relationship.
