The role of opioid peptides in the regulation of secretin-stimulated bile secretion

Abstract

Influence of intraperitoneal dalargin (dand m-opioid agonist), DADLE (d-opioid agonist), DAGO (m-opioid agonist) and U50488 (k-opioid agonist) on bile secretion which is stimulated by secretin was studied in sharp experiments on white rats. All opioids studied is demonstrated to suppress secretory response of liver upon secretin in different extent. We suppose that opioidergic regulation system has different effect on bile secretion in dependence of baseline level of physiologic secretion.
