title: Inhibitory effects of scillaren and dinitrophenol on bilirubin excretion by the isolated perfused rat liver.
abstract: The effects of scillaren and dinitrophenol on bilirubin excretion by the perfused rat liver were studied. Both compounds inhibited bile flow, scillaren by 20 to 40%, and dinitrophenol by 60 to 80%. Bilirubin excretion was also impaired. However, the effect of scillaren on bilirubin excretion was less than that on bile flow, as indicated by an increase in the bile bilirubin concentration, whereas dinitrophenol had a greater effect on bilirubin excretion than on bile flow. Dinitrophenol also inhibited the hepatic removal of unconjugated bilirubin from the perfusate, probably because it impaired the initial uptake and/or storage of unconjugated bilirubin by the perfused liver.
