Free Ca2+ concentration and 45Ca flux were measured in the perfusate and bile of the perfused rat liver. With a perfusate Ca2+ concentration of 1 mM, the bile concentration was 0.35 mM. The ratio of 45Ca in bile to that in blood increased from 0.3 to 0.6 over 90 min of perfusion. Both verapamil and adrenaline (via α-adrenergic receptors) increased the 45Ca bile/perfusate ratio to 0.8. Adrenaline infusion increased the bile Ca2+ concentration to 0.8 mM. This decreased to 0.35 mM after the infusion was stopped.
