Then transplantation of the sciatic nerve from donor rats to the recipient rats in two groups were progressed.7 days after nerve transplantation,the contents of cd4 and cd8 in peripheral plasma of recipient rats were detected by flow cytometry.8 weeks after nerve transplantation,transplanted nerve were observed under light microscope.results:compared with nonirradiated group,the percentage of cd4 and the ratio of cd4 to cd8 in uvb irradiated group were significantly decreased（p＜0.05,p＜0.01）,cd8 percentage was significantly increased（p＜0.01）.conclusion:uvb-irradiated donor splenocytes were injected in the recipient rats through caudal veil,which could induce immunological tolerance to allogeneic transplantation.

未照射组注射未经紫外线照射的供体脾细胞，照射组注射经紫外线照射的脾细胞，7 d后移植供体神经。术后7 d行外周血t淋巴细胞亚群检查，术后8 w行移植神经组织学检查。结果：照射组cd4+百分率、cd4+/cd8+比值较非照射组明显降低（p.01，p.05），cd8+百分率较非照射组明显升高（p.01）。组织学检查显示，照射组的再生神经较非照射组多。结论：尾静脉内注射经紫外线照射的异基因脾细胞可诱导对异体神经移植的特异性免疫耐受。紫外线；脾细胞；免疫耐受；坐骨神经

Nowadays, bone defect has become one of the most important disease which threat people's living quality severely. Today, the most common methods used to healing bone defects include: Autogenous bone grafts and allogenic bone grafts. But autogenous bone grafts have a shortage on donor, difficult to make shape and will bring a complicate disease on donor site; allogenic bone grafts often follow with graft rejective reaction, and have a potential risk of propagation of many disease.

目前，主要应用于临床骨缺损修复的方法有自体骨移植和异体骨移植等，但自体骨移植存在材料来源有限、供骨部位的损伤以及塑形困难等问题；异体骨移植也有潜在的疾病传播隐患以及移植排斥反应等严重后果，因此无论自体骨移植还是异体骨移植均无法完全满足需求，临床急需寻找一种安全有效的骨移植替代材料。

According to Johnson's Rule and IR spectra, their possible structures are suggested. The bonding parameters of those complexes are calculated by ESR parameters. And the crystal field parameters are calculated by using electronic spectral data. It can be seen that the vanadyl complexes in the solution are ionic complexes and that the α〓 values of those complexes decrease following the increasing of the N donor replacing the O donor of water on the equatorial plane in those complexes. This means that the covalent bonding between vanadium and ligand increases as Ser, Phen or Bipy replace water ligands. The results show the competitive coordinate law that the coordination reactivity of Phen and Bipy is much stronger than that of Ser. The simulation program of ESR is compiled by the theory of ESR in the present work.

测定了VO-丝氨酸二元体系、VO-丝氨酸-邻菲咯啉三元体系和VO-丝氨酸联吡啶三元体系在不同酸度下（pH=1.0～14.0）的乙二醇／水（V／V=1：1）溶液低温ESR谱，发现不同pH下，溶液中具有不同组成的配合物，根据不同pH下ESR谱的变化，利用Johnson的加合规则并结合红外光谱，推测了它们在溶液中的可能结构；利用波谱参数计算了配合物键参数；利用电子光谱数据计算了配合物的晶体场参数，讨沦了它们的成配特性，结果表明：VO配合物属离子型配合物，随取代水分子的配体（Ser、Phen或Bipy）数目增加，键参数减小，配合物共价性增强，同时得出这些体系中，生物配体竞争配位规律：Phen和Bipy与VO的配位能力比Ser强。

Methods After brain death of the donor was confirmed, the whole donor arm was sterilized with 3%iodine tincture and 75%ethyl alcohol and strapped with sterile towels.
