    Monosodium glutamate (MSG) treatment of neonatal mice results in a selective damage to the arcuate nucleus (ARC) and development of obesity. The MSG obese mice do not respond to fasting by an increased food intake which makes difficult to measure the effect of peptides attenuating food intake such as cholecystokinin (CCK) or cocaine- and amphetamine-regulated transcript (CART) peptide. However, orexigenic effect of NPY is preserved in the fed MSG obese rodents. In this study with fed lean and MSG obese C57BL/6 male mice, short-term food intake was measured after simultaneous central administration of orexigenic NPY with either CART peptide or peripherally administered CCK. Anorexigenic action of exogenous CART peptide was preserved in MSG obese mice. On the other hand, satiety effect of exogenous CCK was completely lost in MSG obese mice probably because of ineffective leptin signaling in ARC.
