Dissociated neurointermediate lobe cells (75%) bound [biotinyl-Ser1]corticotropin releasing hormone (bio-CRH) and secreted adrenocorticotropin [ACTH(25-39)] in a reverse hemolytic plaque assay (RHPA). The bio-CRH was rapidly internalized (less than 1 min) in vesicles and scattered vacuoles. Plaque percentages increased from 26 +/- 4% to 53 +/- 8% after CRH stimulation. Areas increased from 1688 +/- 791 microns 2 to 3773 +/- 788 microns 2. After AVP treatment for 1 hr, plaque percentages and areas were augmented further. The heterogeneity in secretion may indicate the presence of quiescent IL cells or cells secreting an opiocortin peptide not detected in the plaque assay.

Growth hormone (GH) and beta-endorphin (beta-EP) responses to clonidine stimulation were examined in 18 male heroin addicts, 9 with and 9 without previous histories of attention deficit disorder with hyperactivity (ADD-H) and conduct disorder (CD). Ten psychophysically healthy volunteers were used as controls. ADD-H/CD addicts had blunted GH and beta-EP responses as compared to controls while those of non-ADD-H/CD addicts were normal. This suggests that postsynaptic adrenoceptor sensitivity is decreased and, possibly, that presynaptic noradrenaline secretion is increased in ADD-H/CD patients with heroin addiction.
