ABSTRACT

AIM:

To observe the effects of Sini decoction against pulmonary injury induced by ex vivo ischemia-reperfusion in rats.

METHODS:

The model of ischemia-reperfusion was established. Twenty-four Sprague-Dawley rats were randomly divided into Sham, I/R, and SND groups. Wet to dry lung weight ratio (W/D), mean pulmonary artery pressure (MPAP), SOD activity and MDA contents in pulmonary perfusate and tissue, NOS activity and NO contents in pulmonary tissue were detected. The pathologic changes in pulmonary tissue were also observed by light microscope.

RESULTS:

The morphological changes of pulmonary injury were alleviated in SND group. Wet/dry ratio, MPAP and MDA contents in pulmonary perfusate and tissue were significantly lower in SND group after ischemic/reperfusion. SOD activity in pulmonary perfusate and tissue, and NO contents in pulmonary tissue were significantly higher in SND group than those in I/R group. No significant difference in NOS activity in pulmonary tissue among three groups was observed.

CONCLUSION:

These results indicate that SND may have a protective effect on ischemia-reperfusion injured lung by its antioxidant activity and by adjusting NO level.
