Fundamental and clinical evaluation of vasoactive intestinal peptide (VIP) in pancreatitis by radioimmunoassay kit.
Plasma vasoactive intestinal peptide (VIP) concentrations of normal individuals and patients with pancreatitis were studied using a VIP RIA kit. The inter-assay and intra-assay variation of this kit were between 2.1 and 9.4%. The VIP levels increased in the acute phase of acute pancreatitis and patients with chronic pancreatitis. The VIP concentration increased during the first 30 min of glucose tolerance test, but this increase was much smaller than that in insulin. These results suggest that this kit is useful for physiologic and pathologic changes in the VIP level.
