This study demonstrates the preventive effects of polysaccharides extracted from Arctium lappa roots against acute lung injury induced by lipopolysaccharide. The polysaccharides show anti-inflammatory and antioxidant capacities, reducing inflammatory cell infiltration and alveolar collapse. The study suggests that Arctium lappa polysaccharides have the potential to be an alternative treatment for lung injury.
The objective of this study was to investigate the preventive effects of polysaccharides extracted from the roots of Arctium lappa (ALP) against acute lung injury (ALI) models induced by lipopolysaccharide (LPS). The polysaccharides were extracted and characterized, and their anti-inflammatory and antioxidant capacities were assessed. The findings demonstrated that ALP could mitigate the infiltration of inflammatory cells and reduce alveolar collapse in LPS-induced ALI in mice. The expression levels of the pro-inflammatory factor TNF-alpha decreased, while the anti-inflammatory factor IL-10 increased. Furthermore, the administration of ALP improved the activities of lung antioxidant enzymes, including SOD, GSH, and CAT, and lowered MDA levels. These results suggest that ALP exhibits a preventive effect on ALI and has potential as an alternative treatment for lung injury.
