Alpha 2-adrenergic modulation of pancreatic glucagon secretion in rats.

abstract：:Subjects consumed soup (beef consomme) preloads of a fixed size containing different concentrations of monosodium L-glutamate (MSG). Effects on appetite following these preloads, and when no soup was consumed, were assessed in 3 studies. The soups supplemented with MSG were rated as more "pleasant," more "savoury" and...
