Liposome uptake by lung tissue cells 18 hours after instillation of LPS. Association of ³H-liposomes instilled 2 hours prior to killing in cells isolated from lung tissue. Animals were killed 18 hours after instillation of saline (Con 18) or 100 μg/kg O26:B6 LPS (LPS 18). Lungs were lavaged and type II cells and other tissue-associated cells (plate cells) were isolated. Data are means ± SEM and expressed as DPM/10⁶ cells, n = 7 animals/group.
