There were remarkable differences (P 0.05) of tailing rate and tail long between Guiyu Group and Control Group.

新生儿脐带血铬水平与拖尾率即彗星细胞数和彗星细胞尾长成正相关。

Methods: 30 SPF rats were randomly divided into the health group by tail veins with saline, the doxoruvicin group with doxoruvicin and the aclarubicin group with aclarubicin.

将30只SPF级纯系SD大鼠随机分为3组，正常组尾静脉注射生理盐水，多柔比星组和阿柔比星组尾静脉分别注射多柔比星和阿柔比星。

Results The tail formation rate of model group was significantly higher than the rate of control group (P＜0.05) with a large number of Ⅲ and Ⅳ DNA damage cells. The tail formation rate of dichloromethane extraction groups were both significantly lower than the rate of model group (P＜0.05). p53 mRNA expression of model group was higher than the rest except the crude Cornus Officinalis group.

结果 D-半乳糖致衰模型组小鼠骨髓细胞DNA拖尾率高于正常对照组(P＜0.05)，且Ⅲ、Ⅳ级损伤细胞数较多；山茱萸生品及制品二氯甲烷萃取部位组小鼠骨髓细胞DNA的拖尾率均低于D-半乳糖致衰模型组(P＜0.05)。D-半乳糖致衰模型组小鼠骨髓细胞p53基因的表达高于正常对照组、阳性药组及制品组。

After the animal modle done successfully, all animals were randomly divided into two groups. group l: Microbubble contrast agent containing plasmid was injected into nude mice via the tail vein; group 2: the mixture of microbubbles with plasmid was injected as the group 1, and eyeballs were exposed to ultrasound with intensity of 0.5W/cm^2 immediately, and the time were all 60s that working time control at 20%.

将12只BAlB/C裸小鼠双眼玻璃体腔接种HXO-Rb44细胞，造模成功后，将动物随机分为2组，第1组于尾静脉注入含质粒的微泡造影剂；第2组尾静脉注射质粒与微泡的混合液，并立即以0.5W/平方公分〔1〕的超声波辐照小鼠眼球60s，工作时间控制为20%。

In control group,Ⅰ tail current density of Epi myocytes was 49.1% bigger than that of Mid myocytes, in operation group, which is 77.6%.Ⅰ tail current density had no significant difference among three layers in two groups.

对照组外膜细胞的Ⅰ(下标 Ks尾电流密度较中层细胞大49.1%，而手术组为77.6%；两组三层细胞之间Ⅰ(下标 Kr尾电流密度均无差别。

Following successful modeling, rats of bFGF group were intratracheally injected with 400 U bFGF and rats of VEGF group with 2 μg VEGF, once a week for three times. MSCs group was injected 1 mL suspension of 4×109/L MSCs into tail vein. MSCs+VEGF group was injected MSCs into tail vein and intratracheally injected VEGF (2 ug, three times) at the same time. Model control and normal control groups were intratracheally injected with equal volume of sodium chloride.

成功造模后，碱性成纤维细胞生长因子组气管内注入400 U碱性成纤维细胞生长因子，血管内皮生长因子组气管内注入2 μg血管内皮生长因子，1次/周，共3次；单纯细胞移植组于尾静脉注入4×109 L-1骨髓间充质干细胞悬液1 mL；血管内皮生长因子+细胞移植组气管内注入血管内皮生长因子的同时，尾静脉注入骨髓间充质干细胞；模型对照组、正常对照组给予相同体积的生理盐水。

METHODS: Human AMSCs were isolated in vitro sterilely. At the third passage, 0.5 mL single cell suspension at 1×109/L was obtained and transplanted by tail venous pathway in transplantation group mice, Mice in the control group were injected with an equal volume of saline. APP-gene mice in the normal group were left intact. 5'-bromo-2-deoxyuridine labeled third-generation AMSCs expression was detected in mice brain tissue by immunohistochemical method.

无菌条件下体外分离培养人羊膜间充质干细胞，传至第3代将细胞浓度调整为1×109 L-1，经尾静脉注入0.5 mL至细胞移植组转APP+基因小鼠体内；对照组经尾静脉注入同体积的生理盐水；正常组转APP-基因小鼠不给予任何干预措施。

The mice in experimental group and control group were exposed to 350 cGy radiation produced by 60Co. After 3 h, karyocytes at different concentrations in the fresh human umbilical cord blood were injected into the mice in experimental group A, B, C via their tail veins, and the equal volume of normal sodium was also injected into control group via tail veins. After one month, carbon tetrachloride (CCl4) was injected into experimental group A, B and control group via abdominal cavity, and the equal volume of normal sodium was injected into experimental group C. After two months, immunohistochemistry and reverse transcriptase polymerase chain reaction were used to detect the expressions of human cytokeratin-18 (CK18), cytokeratin-19 (CK19) and albumin in liver tissues of all mice.

采用60Co治疗仪γ射线对实验组和对照组行350cGy的亚致死剂量照射，实验组A、B、C3组照射后3h内经尾静脉分别输入1.0×10^7个/只、2.0×10^7个/只和3.0×l0^7个/只人新鲜脐血有核细胞，对照组经尾静脉注入等体积无菌生理盐水。1个月后对实验A、B组和对照组裸鼠经腹膜腔注射四氯化碳(CCl4)，实验C组注射等体积生理盐水。2个月后采用免疫组化和RT-PCR方法检测裸鼠肝组织人源性CK18、CK19和人源性白蛋白的表达。

Let hair to keep the state in the most pure Should be pruned at any time bifurcation hair tail, because the bifurcation of the hair tail light directly block.

随时都要修剪掉分叉的发尾，因为分岔的髮尾会直接阻挡光线。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
