The concentrations and contents of vasoactive intestinal peptide (VIP) and cholecystokinin (CCK) in the brain and of these peptides along with secretin and glucagon-like immunoreactivity (GLI) in the gut were compared in a group of 16 5-day fasted adult Sprague-Dawley rats with the corresponding peptides in a group of 16 nonfasted littermates. The mean weight of the fasted rats at the beginning of the study was 263 +/- 10 g (+/- SEM) and was 177 +/- 7 g before killing, for a net loss of 33% of… CONTINUE READING
