    Abstract:
    Secretin is known to stimulate the flow of bicarbonate-rich bile from the bile-duct epithelium, but has no effect on hepatocytes. To investigate the effects of secretin on bile production during intrahepatic cholestasis, we infused secretin into rats with taurocholate-induced cholestasis. Secretin was given at 0.25 and 0.50 units.min-1.kg-1 to Wistar rats that simultaneously received a continuous infusion of taurocholic acid at above its maximum hepatic transport capacity to produce cholestasis. When taurocholic acid was infused at doses of 1.4 and 1.6 mumol.min-1.100 g b.w.-1, bile volume decreased in control rats. In contrast, the simultaneous infusion of secretin significantly increased bile flow and the biliary excretion of bile acids and bicarbonate. The serum taurocholic acid level at the end of the experiment was significantly lower in the secretin-treated groups than in the control group. These findings indicate that secretin prevents taurocholate-induced cholestasis and may enhance the biliary excretion of bile acids.
