Dehydroepiandrosterone functions as more than an antiglucocorticoid in preserving immunocompetence after thermal injury.

abstract：:Low basal GH secretion and reduced GH responsiveness to different GH secretagogues, including GHRF, have been reported in aged animals and humans. Parallel to the in vivo findings, an impaired GH responsiveness to GHRF is evident in somatotropes from old rats of either sex. We report here that in anterior pituitaries ...
