Effects of the novel gastrointestinal polypeptide PHI with N-terminal histidine, C-terminal isoleucine amide, and 27 amino acids have been studied in isolated perfused rat pancreas. PHI increased the release of insulin, glucagon, and somatostatin. The amounts of these hormones released were strictly dependent on the prevailing glucose concentrations. In the absence of glucose, PHI (1 nmol/liter) stimulated glucagon release. In the presence of 4.4 and 6.7 mmol/liter glucose, the same dose of this peptide stimulated insulin and somatostatin release. In the presence of 16.7 mmol/liter glucose, only insulin secretion was increased by PHI. When arginine was used as a secretagogue, PHI (10 nmol/liter) potentiated secretion of insulin, glucagon, and somatostatin. Thus, PHI may take part in the regulation of the function of the pancreatic A, B, and D cells.

The effects of both synthetic and pure natural porcine secretin on immunoreactive insulin (IRI) and immunoreactive glucagon (IRG) release and on pancreatic exocrine secretion were studied in the isolated perfused rat pancreas. Synthetic porcine secretin stimulated a significant increase in pancreatic juice flow and amylase output at concentrations as low as 0.01 and 0.1 ng/ml, respectively. The maximal peak rate of both juice flow and amylase output was observed at 1 microgram/ml synthetic secretin. Synthetic secretin at concentrations up to 2 micrograms/ml and pure natural porcine secretin at a concentration of 1 clinical unit/ml had no effect on IRI secretion regardless of the glucose concentration (50, 100, or 150 mg/100 ml) in the perfusate. Both types of secretin, however, elicited a concentration-dependent increase in IRG secretion in the presence of 50 mg/100 ml glucose. The lowest synthetic secretin concentration causing a significant increase in IRG release was 0.1 ng/ml, and maximal stimulation was observed at 1 microgram/ml. These concentrations were similar to those eliciting minimal and maximal amylase release. Thus, synthetic and pure natural porcine secretin have been shown to not only stimulate pancreatic juice flow and amylase secretion but also to elicit IRG release from the isolated perfused rat pancreas.
