From: In vivo clearance of surfactant lipids during acute pulmonary inflammation.
Alveolar surfactant protein A (SP-A) levels. Relative quantities of alveolar SP-A were measured by Western Blot. Equal volumes of bronchoalveolar lavage fluid (BALF) from the individual animals were utilized and total BALF recovery was not different among these animals. Lanes 1 and 2 represent individual animals that were lavaged 18 hours after saline instillation. Lanes 3 and 4 represent individual animals that were lavaged 18 hours after instillation of 100 μg/kg O26:B6 lipopolysaccharide (LPS). Lanes 5 and 6 represent animals lavaged 72 hours after instillation of 100 μg/kg 026:B6 LPS.
