摘要: 目的: 建立一种简便可靠的兔肾移植模型。方法: 用新西兰白兔作为供体和受体。供受体腹主动脉和下腔静脉分别行端--侧吻合;输尿管带膀胱瓣与膀胱吻合。结果: 新西兰白兔肾移植模型稳定;肾移植组兔术后第2天起,血清肌酐浓度(SCr)迅速上升,从术前(179.76±28.36)μmol/L上升到术后的(693.55±36.49)μmol/L,而对照组血清肌酐浓度较稳定;一般情况观察和移植肾外观形态检查均出现典型急排反应。结论: 新西兰白兔肾移植模型制作简便、可靠,可用于移植免疫学研究。Abstract: Objective: To establish a simple and reliable rabbit model of renal allograft transplantation. Methods: New-zealand white rabbits were used as the donor and recipient.End-to-side anastomosis of the donor’s inferior vena cava to recipient’s inferior vena cava was performed.End-to-side anastomosis of the donor’s abdominal aortas to recipient’s abdominal aortas was performed.Urinary tract reconstruction was accomplished by suturing the donor’s ureter with a bladder patch to the recipient’s bladder. Results: The rabbit model of renal allograft transplantation was reliable.The serum creatinine(SCr)level increased from(179.76±28.36)μmol/L to(693.55±36.49)μmol/L in transplantation group after surgery.The serum SCr level remained stable in the control group.Typical changes of acute renal rejection occurred in the rabbit model of renal allograft transplantation. Conclusion: Rabbit model of renal allograft transplantation is simple and reliable,and thus can be used as a model to study transplantation immunity.
