Rattus norvegicus

-

animals drinking a 2.5% NaCl solution for 7 d present body weight reduction. Despite their negative energy balance, they avoid food and have increased hypothalamic paraventricular nucleus thyrotropin releasing hormone expression and thyroid-stimulating hormone serum levels. Increased medial basal hypothalamic pyroglutamyl-aminopeptidase II activity in dehydration-induced anorexia rats might counteract their high thyrotropin releasing hormone release
