Fig. 5From: Intravenous superoxide dismutase as a protective agent to prevent impairment of lung function induced by high tidal volume ventilationHTV ventilation markedly increased lavage content of WBC versus the LTV group. HTV ventilation increases percent neutrophils in BALF. Though absolute macrophages (lower panel) increased after HTV ventilation, the percent macrophages decreased. SOD treatment during HTV ventilation markedly reduced total white blood cells and the percentage of neutrophils in BALF (* and # signify PÂ <Â 0.05 and PÂ <Â 0.001, respectively)Back to article page
