Application of ultrasound in assessment of acute lung injury in mice.

ABSTRACT: This study evaluated the effectiveness of non-invasive ultrasound technology in monitoring pulmonary edema in a mouse model of acute lung injury (ALI). Male C57BL/6J mice were instilled through the trachea with lipopolysaccharide (LPS, 5 mg/kg, single dose) to induce ALI. The change in B-lines (an ultrasound sign) were monitored using the Vevo 3100 system and the lung ultrasound (LUS) score was generated to quantify the severity of edema, meanwhile lung function was assessed by whole-body plethysmography (WBP) and the progression of ALI was tracked by lung weight and histopathological analysis. LUS detection revealed that non-converging B-lines appeared on the first day, followed by an increase in the number of B-lines that began to converge, peaking on the day-3 and then the number of B-l
