Objective:
To investigate the effect of Shengdi injection on rat model of lung inflammation.
Method:
The rat model was established by intratrachea instillation of lipopolysaccharides (LPS). The total and different white blood cell counts in bronchoalvoelar lavage fluid (BALF) were performed and the level of tumor necrosis factor-alpha (TNF-alpha), superoxide anion radical (O2-) and myeloperoxidase (MPO) was measured, as well as pathologic change of pulmonary tissue was tested.
Result:
Shengdi injection could depress the increasing of the amount of total white blood cells and neutrophils and inhibit the increasing of TNF-alpha, O2-, MPO caused by LPS, as well as relieve the pathologic change including Neutrophils infiltrating and mucous edema in tracheae after intravenous administration. While it did not show the effect on monocyte, and histological lesion of the lung tissue.
Conclusion:
Shengdi injection shows some anti-inflammatory effect in rat lung induced by LPS and it can be concluded tentatively that anti-inflammatory, inhibiting the release of cytokine and inflammatory medium, and antioxidation are some of the mechanism of its effect on COPD.
