“At 24 h, lung-tissue rhSOD … higher in rats treated with surfactant … rhSOD versus rhSOD alone (5 mg/kg: 6.8 +/- 2.5 versus 0 microgram/whole lung, p < 0.05; 25 mg/kg: 29.9 +/- 9.6 versus 0.1 +/- 0.1 microgram/whole lung, p < 0.05).”
“This finding suggests that the rhSOD and surfactant were only weakly associated.”
