The biliary excretion of 3H-inulin and 3H-terbutaline in the unanesthetized rat.
An animal model which permits sampling of arterial blood and bile from unanesthetized rats with uninterrupted enterohepatic circulation is described. Pharmacokinetic data concerning inulin (0.2 mumol kg-1) and terbutaline (1.8 mumol kg-1) after intraarterial injection are presented. The following values for inulin were obtained Vdbeta equals 0.25 ml g-1, plasma clearance equals 2.3 ml min-1 kg-1 and bile clearance equals 0.03-0.04 ml min-1 kg-1, which mainly are in agreement with data from the literature. For terbutaline the corresponding values were 0.58 ml g-1, 5.2 ml min-1 kg-1 and 0.12-0.98 ml min-1 kg-1, respectively.
