Methods.Rat kidney transplantation was performed according to the procedure of Kamada with some modification.Experimental rats were divided into 5 groups.The survival time of recipient rats and function of grafts after renal transplantation were observed.The sections of renal graft were stained for monoclonal antibody ICAM 1 and LFA 1, and then quantification of ICAM 1 and LFA 1 expression was accomplished by computer image analysis. Results.ICAM 1 and LFA 1 increased significantly in the renal allograft rejection group as compared with the non rejection groups(P<0 05). Conclusion.Both biopsy of renal graft and monitoring of ICAM 1 and LFA 1 are useful tools in diagnosing and treating acute rejection.展开更多
文摘目的采用短小棒状杆菌制剂对小白鼠ICAM1/LFA1基因表达的研究,从而进一步研究短小棒状杆菌制剂对免疫调节和抗肿瘤机理深入研究提出依据。方法本试验采用realtime PCR方法,以GAPDH和-βactin分别作为各组织样品的内源控制基因。结果短小棒状杆菌制剂短小棒状杆菌制剂小白鼠腹腔注射之后,ICAM1基因在脾脏组织中上调,5 h出现高峰,短小棒状杆菌制剂小白鼠腹腔注射之后3-5 h LFA-1基因持续性上调。不同组织的LAF-1基因检测结果显示,小肠和脾脏均表现为高表达,尤以脾脏突出。结论短小棒状杆菌制剂的免疫机理和治疗肿瘤的作用与早期激动免疫细胞的第一信号有直接相关。
