The biliary excretion of sulfbromophthalein in the pig
Authors:M Rose  J M Ham
Abstract:The characteristics of the hepatic metabolism of Sulfbromophthalein (BSP) have not been described previously for the pig. This is an important deficiency, since the pig is particularly suitable for studies of hepatic physiology and pharmacology which might apply to man. The aim of these experiments was to establish the pattern of serum clearance and biliary excretion of BSP and to determine that dose which would produce a maximal concentration in bile. A dose response and pattern of biliary excretion of BSP was studied at three dose levels administered either as a single bolus of a continuous infusion. All experiments were performed in conscious, conditioned pigs. The patterns of serum clearance and biliary excretion were found to be similar to other laboratory animals and to man. Maximary biliary concentration of BSP was achieved by a single bolus of 5-9 mumol/kg or a constant infusion of 0-59 mumol/kg/min. At these dose levels no significant alteration in bile flow was demonstrated nor was there any correlation between bile flow and BSP excretion. Supra-maximal doses produced a significant increase in bile flow and with these doses there was a significant positive correlation between bile flow and BSP excretion.
