ABSTRACT
Objective To investigate the effects of intravenous immunoglobulin(IVIG) on apoptosis and necrosis of myocytes in mice with viral myocarditis.Methods Three hundreds and twenty Balb/c mice were randomly divided into 8 groups.Different courses of IVIG were given in varying time after virus inoculation,Chinese medicine Huangqi given in control group.The virus titer in myocardium、percentage of apoptosis and necrosis of myocytes were detected, myocardial histopathologic scores were counted.Results In every IVIG treatment group,the above 3 items were all significantly lower than that in virus control group and Huangqi group,as IVIG early long course group had the best effect.Conclusion IVIG may reduce the percentage of apoptosis and necrosis of myocytes and virus titer in myocardium in mice with viral myocarditis,the effects are better than that of Huangqi.
ABSTRACT
Objective To investigate the expression of vascular endothelial growth factor(VEGF)in synovium of rats with adjuvant arthritis and the relationship between the histopathologic score and the expression of VEGF.Methods Adjuvant arthritis was established in Wistar rats by inoculating complete Freund's adjuvant(CFA). We calculated the arthropathologic score and the expression of VEGF mRNA and protein at different stages after CFA inoculation.Results In model group the arthropathologic score and expression of VEGF protein in synovium increased significantly all the time (P
