Peptide histidine isoleucine (PHI). A secretagogue in porcine intestine.
PHI (peptide histidine isoleucine) is a recently identified porcine peptide, present in large quantities in the intestine, which has sequence homologies with VIP, an established intestinal secretagogue, and with secretin, glucagon, and GIP. The effects of PHI on jejunal, ileal, and colonic fluid and electrolyte transport were studied in the pig. PHI appears to be an intestinal secretagogue inducing a reversible net secretion of fluid and electrolytes in jejunum and ileum and less marked effects in the colon.
