The results showed that among three regulator combinations (2, 4-D KT and IBA), 2, 4-D2~3 mgL^(-1 treatment was the best with the highest callus induction rate, most of the explants induced callus and grew well. 2, 4-D2mgL^(-1+KT0.5mgL^(-1 treatment could induce callus from stem parts while the callus induced from the stem top was water-soaked and easy to be brown stained. KT4mgL^(-1 treatment could induce callus on some stems but was easy to be brown stained. KT4mgL^(-+IBA0.5mgL^(-1 treatment could induce callus but they grew very slowly.

试验结果表明：在3种生长调节剂(2， 4-D、KT、IBA)的组合中，以2，4-D2~3mgL^(-1效果最好，愈伤组织的诱导率最高，大部分外植体都能诱导出愈伤组织，生长良好；2，4-D 2mgL^(-1)+KT0.5mgL^(-1)能使部分茎段诱导出愈伤组织，而茎尖诱导的愈伤组织水渍化，易褐变；KT 4mgL^(-1)能使个别茎段有愈伤组织产生，但易褐化；KT 4mgL^(-1)+IBA 0.5mgL^(-1)能诱导出愈伤组织，但生长缓慢。

作为成体干细胞中的一种，脐血间质干细胞具有良好的多向分化潜能、活跃的增殖特性、对外源基因的高效转染表达能力以及促进造血、在体外较易分离、培养等特性，日益引起国内外研究者的浓厚兴趣。

The results indicated that: compared with mono-cropping, the mean densities of rice stem borers, leaf roller, rice hoppers and leafhoppers in scale rice-duck farming were decreased by 54.4%, 48.8%, 73.6% and 96.1% respectively, and the rate of diseased plant of sheath blight and rice blast in IF were decreased by 78.9% and 48.5% respectively. Compared with the conventional rice-duck farming, the average densities of rice stem borer, rice leaf roller, rice hoppers and leafhoppers in IF was reduced by 18.2%, 9.5%, 7.0% and 0.82% respectively, and the rate of diseased plant of sheath blight in IF were decreased by 35.5%, unfortunately that of rice blast in IF was increased by 8.0%.

结果表明：规模稻鸭生态种养水稻二化螟、稻纵卷叶螟、稻飞虱和稻叶蝉平均虫量较水稻单一种植分别下降54.4%，48.8%，73.6%和96.1%，纹枯病和稻瘟病病株率分别降低78.9%和48.5%；较常规稻鸭生态种养水稻二化螟、稻纵卷叶螟、稻飞虱和稻叶蝉量分别下降18.2%，9.5%，7.0%和0.82%，纹枯病病株率降低35.5%，稻瘟病病株率升高8.0%。

Another stem cell source that is being pursued, and that may in fact be closer to the goal of producing a variety of bone fide spinal cord cells, is stem cells from the spinal cord itself.

另外一个可以被利用的细胞来源，也可以说是最可能产生各种不同类型的脊髓细胞的细胞来源，应该是脊髓本身来源的干细胞。

The quantity of CD3+ cells in the EdNSC, AdNSC of cloning goattransplantation group and control group had no statistics difference(P＞0.05) at acute and chronic period.Overall, in our study, We got the conclusions as follow: 1,The EdNSC, AdNSCof cloning goat and the AdNSC of the non-cloning goat were successful obtained;EdNSC growed faster than AdNSC in the same cell culture method. 2,The braincontusion and laceration model of cloning goats were successful established by freefalling of 50 gram of steel ball accelerate strike on the goat brain from 100cm height.3, EdNSC and AdNSC transplantation both had obvious therapeutic effect on braincontusion and laceration of cloning goats; The therapeutic effect of EdNSCtransplantation was better. 4, Allograft of stem cells has acute and chronicimmunological rejection and autografting of stem cells has no acute and chronicimmunological rejection.

在相同的条件下，EdNSC体外培养速度比成AdNSC快。2对羊脑上薛氏沟周围运动皮层区使用50g×100 cm力度作自由落体加速撞击，可产生观察指标明确且存活率高的羊脑挫裂伤模型，有望广泛用于神经干细胞移植及药物等治疗的实验研究。3胚胎神经干细胞及成体神经干细胞移植治疗脑挫裂伤后均有较明显的治疗效果；二者相比较而言胚胎神经干细胞稍好于成体神经干细胞。4中枢神经系统异体神经干细胞移植存在着明显的免疫排斥反应，而自体神经干细胞移植基本无免疫排斥反应
