Results The expression levels of γ-IFN and IGTP in allograft were higher compared with that in isograft, and expression of IGTP was even more significant than γ-IFN in allgraft. In islgraft the expression levels of the both were very low or beyond the capacity to be detected.

结果γ-干扰素和γ-干扰素诱导基因在异基因移植物中显著表达，且γ-干扰素诱导基因的表达水平高于γ-干扰素，在同基因移植物中2个基因表达水平很低，甚至难以检测出。

aim to assess relationship between the increased lfa-1expression in intestine graft and acute rejection,and inhibitory effects of fk506on the expression of lfa-1.methods heterotopic small intestine transplantation was performed on inbred sd and wistar/a rats.the rats were randomly divided into4groups:control groups;isograft group（wistar/a→wistar/a）;allograft group（sd→wistar/a）;allograft plus fk506group（sd→wistar/a+fk506）,

目的 探讨大鼠移植小肠组织内淋巴细胞相关抗原-1（lfa-1）的异常表达与急性排斥反应之间的关系，及fk506对其的抑制作用。方法选用近交系封闭群sd和wistar/a大鼠进行全小肠异位移植。实验分4组：非手术对照组；同基因移植组（wistar/a→wistar/a）；异基因移植组（sd→wistar/a）；异基因移植加用fk506治疗组［sd→wistar/a+fk506

The method is simple, has safe operation, creates an approach utilizing a plant gene to safely select the marker gene for the tomato genetic transformation, can replace the disadvantages caused by the widely used heterogenous genes such as antibiotic genes, weedicide resistant genes, xyl A, pmi, GUS and so on, taken as marker genes, obtains a transgenic tomato with food safety, biological safety and ecological safety, relieves the public from anxiety of marker gene safety, and inevitably facilitates the commercialized application of the transgenic tomato.

该方法简单，操作安全，开创了利用植物基因作为番茄转化安全筛选标记基因的途径，能够代替目前广泛使用的抗生素基因、抗除草剂基因以及xylA、pmi、GUS等异源基因作为标记基因存在的弊端，获得具有食品安全性、生物安全性和生态安全性的转基因番茄，解除公众对标记基因安全性的顾虑，必将促进转基因番茄的商业化应用。

ConclusionThe first experiment Immunetolerance in mice sciatic nerve allograft by intrathymic injection of allogene : the specific immune tolerance can be induced in the sciatic nerve allograft by intrathymus injection of MHC allogene.

研究结论：第一部分：小鼠胸腺内注射异基因抗原在同种异体坐骨神经移植免疫耐受中的作用胸腺内注射异基因MHC抗原可诱导异体坐骨神经移植的特异性免疫耐受。

OBJECTIVE: To observe the effects of intrathymic injection of allogenic antigen on inducing immunological tolerance in nerve transplantation.

目的：观察胸腺内注射异基因抗原在同种异基因神经移植免疫耐受中的作用。

The heterogenic C57BL/6J splenocytes disappeared at 1 day after transfusion, but the syngeneic BALB/c splenocytes could survive for a long time in the peripheral blood of BALB/c mice. The fluorescence intensity was not decreased in two kinds of splenocytes. The results demonstrated that CFSE-labeling with difference concentration is reliable, stable and convenient for spleen lymphocytes tracing in vivo.

异基因的C57BL/6J脾细胞在输注1 d后就快速消失，而同基因BALB/c脾细胞能够在BALB/c小鼠外周血中长期存在，但是两种细胞荧光强度均未见降低，说明荧光染料CFSE差异浓度标记活细胞进行体内示踪是一种稳定的示踪方法。

A trivalent plant expression vector containing Bt cry1Ah gene, cry1Ie gene and glyphosate-tolerant 2mG2-epsps gene was constructed, glyphosate isopropylamine salt as a screening agent, 2mG2-epsps gene as a selectable maker gene. The vector was transfer into maize immature embryonic calli by microprojectile bombardment, and 69 T0 generation plants were obtained. PCR analysis showed that 17 plants had the integration of insect-resistant cry1Ah, cry1Ie gene and glyphosate-tolerance 2mG2-epsps gene.

同时构建了含有Bt cry1Ah和cry1Ie基因和耐草甘膦2mG2-epsps基因的三价植物表达载体，通过基因枪轰击法转化玉米愈伤组织，以2mG2-epsps为筛选标记基因，以草甘膦异丙胺盐作为筛选剂，获得T0代转化植株69株，PCR检测结果表明：有17株已完整的整合有抗虫基因cry1Ah、cry1Ie和耐草甘膦基因2mG2-epsps的3个目的基因，RT-PCR分析外源基因可以正确转录，已获得结实转基因植株。

Optionally, hematopoietic stem cells, autologous, syngeneic, allogeneic or xenogeneic, are delivered to increase the speed of regeneration of the patient's immune system.

可选择地，输入自体的、同种同基因的、同种异基因的、或异种异基因的造血干细胞，来增加患者免疫系统重建的速度。

The cells may be autologous, syngeneic, allogeneic or xenogeneic, as tolerance to foreign cells is created in the patient during reactivation of the thymus.

因为患者在胸腺重新活化过程中产生外来细胞抗性，因而这些细胞可以是自体的、同种同基因的、同种异基因的、或异种异基因的。
