Biodistribution of intravenous injection and inhalation of micelles in rats.

Notes: (A) Dissected organs of rats killed at 1, 6, and 12 hours after inhalation and intravenous injection of DiR-labeled P123 micelles; (B) distribution of DiR in the lung after inhalation of DiR-labeled P123 micelles; (C) ratio of fluorescence intensity in the lung to all organs (heart, liver, spleen, lung, and kidney) after inhalation and intravenous injection of DiR-labeled P123 micelles; (D) fluorescence intensity in the lung after inhalation and intravenous injection of DiR-labeled P123 micelles. ***P<0.001 compared with inhalation. Values expressed as means ± SD (n=3).

Abbreviation: P123, Pluronic P123.
