Theses and Dissertations
The kinetics and mechanisms of macromclecular absorption from the airways of the rat lung were studied in vivo and in vitro, following identical solute administration methods. The isolated perfused rat lung (IPRL) was used as an in vitro model, and the disposition of 7.4 and 4.3 kDa fluorophore-labeled polyhydroxyethylaspartamide (F-PHEA) and other small and macromolecular reference solutes was investigated across doses and in the presence of a variety of biochemical inhibitors.
Absorption profiles of F-PHEA, and the solute's lung distribution at different times after administration, were statistically identical in vivo and in vitro, showing that the IPRL possessed a viable …
