RESUMEN
Objective To study the effect of Yangfei Huoxue Prescription on ERK1/2 and NFK-B of bleomycin-induced pulmonary fibrosis in rats. Methods All of rats were randomly divided into seven groups and were intratracheally infused with bleomycin to build the model. Sham operation group and model group were given 5‰ CMC, dexamethasone group was given dexarnethasone solution, and each treatment group was given corresponding Chinese medicine mixture. After histological process, the expression of ERK1/2 and NFK-B were examined by SABC immunohistochemical method. Results Expression of ERK1/2 and NFK-B in model group were higher than that in sham operation group (P
RESUMEN
Objective To investigate the therapeutic mechanism of Shengjiang Powder(SP)on acute lung injury.Methods Forty healthy SD male rats were divided into 3 groups randomly: normal group,model group,and SP group.After administration for 6 days,acute lung injury rat models were established by injecting lipopolysaccharide(LPS)into sublingual vein.Lung histological sections were prepared for the detection of NF-?B expression by immmunohistochemistry.The images of the lung histological sections were captured and the average gray values of nucleus of endothelial cells in lung micrangium were measured.Results Compared with the model group,SP could depress the expression of NF-?B in the nucleus of lung microvascular endothelial cells,and statistical difference existed between the two groups(P
