Wistar-to-SD rat pancreas transplantation was performed in 35 SD rat recipients with diabetes-induced. Denor antigen was administered through IV or PV and the antigen treatment was performed before or during the transplantation. Graft vein was drained into IV or PV.The results showed that donor antigen pretreatment via PV combined with graft drainage PV synergistically prolongs the pancreas graft survival, and the effect of simultananeous antigen treatment during transplantation is not as satisfactory...

以35只雄性SD大鼠为受体,制成糖尿病模型,以同龄Wistar雄性大鼠为供体,行全胰腺移植。供体抗原分别经门静脉或周围静脉处理,处理时间分别为移植前预处理或移植时处理,移植物静脉分别从门静脉或下腔静脉回流,结果表明供体抗原经门静脉预处理及移植物从门静脉回流对胰腺移植物功能存活的延长具有协同效应,移植时处理延长胰腺移植物效果不如移植前预处理,但可能具有一定的实用意义。

Objective To study the mechanism of graft vein stenosis. Methods A rat experimental model of autogenous vein graft was established by transplanting the right external jungular vein into the infrarenal abdominal aorta in 100 Wister rats. Electric microscope, TUNEL and immunohistochemical S P technique were used to detect the apoptosis, the expression of apoptosis related gene bcl 2 and bax and proliferation cell nuclear antigen (PCNA) of smooth muscle cells(SMCs) in vein graft....

Objective To study the mechanism of graft vein stenosis. Methods A rat experimental model of autogenous vein graft was established by transplanting the right external jungular vein into the infrarenal abdominal aorta in 100 Wister rats. Electric microscope, TUNEL and immunohistochemical S P technique were used to detect the apoptosis, the expression of apoptosis related gene bcl 2 and bax and proliferation cell nuclear antigen (PCNA) of smooth muscle cells(SMCs) in vein graft. Results From 1 to 8 weeks after replacement,the expression of apoptosis and PCNA of SMCs was continuously higher than the control group ( P <0.01). From 1 to 2 weeks,the expression of TUNEL and PCNA showed peak value. From 1 to 2 weeks,the positive rate of apoptosis was lower than that of PCNA, but from 4 to 8 weeks, the positive rate of TUNEL was higher than that of PCNA. There was obvious positive correlation between the expression of TUNEL and PCNA ( r =0.813 P <0.05). One to 2 weeks after vein grafting, bcl 2 positive rate increased and was more different than the control group and the group of 4 to 8 weeks after vein grafting ( P <0.010). The imbalance of proliferation and apoptosis may be related to the vessel remodeling and vein graft stenosis, and bcl 2 and bax protein may involve in the regulation of apoptosis of VSMC. Adopting the mixed strategy to regulate the balance between proliferation and apoptosis may be useful to prevent vein graft stenosis.

目的探讨移植静脉狭窄的发生机制。方法建立100只Wistar大鼠自体颈静脉移植与肾下腹主动脉模型。采用透射电镜、原位DNA片断末端标记(TUNEL)和免疫组织化学法,检测移植静脉血管平滑肌细胞(VSMCs)凋亡及相关基因bal2、bax蛋白和增殖细胞核抗原(PCNA)的表达。结果术后1~8周,移植静脉TUNEL及PCNA阳性VSMCs多于对照静脉(P<0.01);术后1~2周为TUNEL及PCNA表达高峰;术后1~2周,VSMCs凋亡低于增殖、4~8周凋亡高于增殖,具有相关性(r=0.813,P<0.05)。术后1~2周,bcl2表达增多与对照及4~8周组间差异有极显著意义(P<0^01);移植后1~6周,bax表达显著高于对照及术后8周组(P<0.01)。结论VSMCs的增殖和凋亡失衡与移植静脉的重塑和狭窄有关;bcl2与bax蛋白参与了VSMCs凋亡的调节;防治移植静脉狭窄应采用调节增殖与凋亡平衡的联合策略。
