Modification of hormonal responses to arginine by alpha-adrenergic blockade.
alpha-Adrenergic blockade with phentolamine significantly enhances the insulin response to arginine. In women phentolamine may inhibit the growth hormone response to arginine. It is suggested that adrenergic mechanisms may act as modulators in hormonal responses to infused amino-acid.
