Abstract:
Objective: To investigate the effects of grasp seed procyanidins(GSP,原青花素) on lipopolysaccharide(LPS)induced acute lung injury(ALI) in rats with renal function damage and the related possible molecular mechanisms.Methods: The homogenates of lung and kidney were prepared and venous blood were collected at 6 hours after injection of LPS and medicine.The changes of contents of creatinine(Cr),blood urea nitrogen(BUN),lactic acid(Lac) and nitric oxide(NO) in the blood were measured.The enzyme linked immunosorbent assay(ELISA) was used to measure the levels of tumor necrosis factor?(TNF-?),interleukin-1?(IL-1?),monocyte chemoattractant protein-1(MCP-1) and IL-6 in the serum,lung and renal cortex tissue homogenate in various groups.The histopathological changes of lung tissues were observed.The pulmonary vascular permeability and the lung wet/dry(W/D) weight ratio were determined;the malonaldehyde(MDA) content,Na+K+-ATPase,superoxide dismutase(SOD),myeloperoxidase(MPO) and glutathion peroxidase(GSH-Px) activities in lung and renal tissues were also determined.Changes of mitogen activated protein kinase(MAPKs) were detected by Western blotting,and the combination activity of nuclear factor-?B(NF-?B) to DNA was detected by electrophoretic mobility shift assay (EMSA) in lung tissues.Results: ①Compared with the normal rats in control group,the lungs of the rats in LPS treatment group and GSP group had significant hyperemia and spotted hemorrhage.The inflammatory granulocyte infiltration,diffuse alveolar septum thickening and spotted hemorrhage were observed in the pathological examinations,while in LPS plus GSP group the above mentioned pathological changes were milder.②Compared with control group,the lung W/D and pulmonary vascular permeability were much higher in the LPS treatment groups(P
