Drug CRL 40 028-induced inhibition of pancreatic secretion in rats.


PMID 6139981

Abstract

The drug CRL 40 028 increases spontaneous motility through an action on central adrenergic receptors. The effects of this drug have been tested in rats on the external pancreatic secretion induced by secretin, CCK, acetylcholine, vagal electrical stimulation or 2 deoxy-D-glucose. CRL 40 028 had no effect on basal secretion nor on secretion stimulated by agents acting directly on pancreatic secretory cells (secretin, CCK, acetylcholine), but decreased significantly secretion induced by central or peripheral stimulation of the vagus nerves. CRL 40 028-induced inhibition of 2 DG effect was reduced by yohimbine, suggesting a participation of alpha 2-adrenergic receptors in the action of CRL 40 028 on the exocrine pancreas secretion of rats.
