title: Biliary excretion of [14C]taurocholate by rainbow trout (Salmo gairdneri) is stimulated at warmer acclimation temperature.
abstract: Sexually immature Shasta strain rainbow trout (Salmo gairdneri) of either sex were acclimated at 10, 14 or 18 degrees C for at least 4 weeks and plasma pharmacokinetics and biliary excretion of i.p. injected [14C]taurocholate (TC) examined in spinally transected or free-swimming fish, respectively. Plasma elimination half-lives but not absorption rate constants for [14C]TC (10 mumol/kg) were about two-fold reduced in 18 as compared to 10 or 14 degrees C acclimated fish. Distribution of [14C]TC to tissues other than plasma, liver, bile and small intestine was not different in 10, 14 or 18 degrees C acclimated free-swimming fish at 1 or 4 hr post-injection. Biliary excretion of [14C]TC (7.5-10 mumol/kg) at 1 hr post-injection was significantly higher in 14 and 18 as compared to 10 degrees C acclimated fish.
