Abstract:
:Pharmacokinetics of recombinant human basic fibroblast growth factor (rhbFGF) in mice were studied by using a radioiodination method combined with sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) and a sandwich enzyme-Linked immunosorbent assay (ELISA). RhbFGF concentration in serum were dertermined after iv administration of 2.5, 5 and 10 microg/kg of 125I-rhbFGF or rhbFGF. The AUCs were linearly correlated to doses. Concentrations in tissues, recoveries of 125I-rhbFGF in urine and feces were also analyzed following iv dose of 5 microg/kg. Pharmacokinetic profiles of radiolabelled and unlabelled rhbFGF were consistent in trend but exit certain differences. Mice cleared unlabeled rhbFGF markedly faster than their radiolabeled counterparts.
