Abstract:
Objective To investigate the effects of chemokine antagonist,Met-RANTES,on the acute rejection of islet allograft in the rat model.Methods According to the different treatments,rats were divided into 2 group: control group,allogeneic islet transplant untreated;experiment group,allogeneic islet transplant treated with Met-RANTES(200 ?g/day, i.p) for 7 days post-operation.The survival time of rat of islet transplant and blood sugar were recorded,and the pathological changes of islet allograft were observed.Scintillation counter was used to count the count per min(cpm) of monocytes.Flow cytometry was used to detect the ratio of CD4~+/CD8~+ phenotypes and CCR5 expression of peripheral blood lymphocytes.Results The mean survival time of islet allograft in experiment group was(23.0)?(10.5) days,obviously longer than in the control group((3.8)?(4.5) days,P
