Corticotropin-releasing factor (CRF) injected intraperitoneally decreases vasoactive intestinal peptide (VIP) concentrations in the terminal ileum (A) and does not change VIP levels in the portal vein (B). Rats were injected with vehicle or CRF (10 µg/kg ip) and euthanized 1 h later. Blood was withdrawn from the portal vein, and the terminal ileum was collected. Data are means ± SE, and rats/group are indicated in each bar. *P < 0.05 vs. vehicle (Student’s t-test).
