查询词典 the positive

ANP and CX43 began to express at 2nd week after induction and increased gradually,about 60% of the resulting myogenic cells were positive at 4th week after induction ,they were negative for uninduced cells.hMSCs'surface antigen profiles obtained by Flow Cytometry were negative for CD31\CD34\CD45 before and after induction,but CD90 expressed higher after induction while was weak positive before induction(P.05). Apotosis index was correlated with the cultural time after induction,The apoptosis rate of induced hMSCs was remarkably higher than control group(P.01),and the variation between groups was notable(P.05),the cell cycle analysis showed that the percentages of G_0/G_1phases were reduced significantly after induction. The expresstion levels ofβ-MHC and CTNT mRNA were undetectable before induction,began to increase at 1st、4th week after induction,reached the peak at 6th week and decreased after that,the expression of Bcl-2 and Bax mRNA varied regularly after treated with 5-azacytidine. hMSCs'resting membrane potential、range and rate of depolarization were heightened gradually after being induced.

结果：hMSCs诱导前为纺锤形，诱导后第2天部分细胞即开始发生形变，呈球形或短棒状，1周后胞浆中颗粒增多，约20～30%细胞边缘呈毛刷样变化；hMSCs表面抗原CD31、CD34、CD45在诱导前后差异无统计学意义，CD90未诱导时表达呈弱阳性，诱导后明显增高(P.05)；ANP和CX43在诱导前无表达，诱导后第2周开始表达且表达随时间逐渐增强，但CX43在诱导后第5周表达量开始降低。hMSCs诱导后凋亡指数随诱导后培养时间增加，低浓度诱导组低于标准浓度诱导组，组间差异有统计学意义(P.05)，G_0/G_1期细胞比例诱导后较对照组显著减少(P.05)；β-MHC和CTNT基因分别在诱导后第1周和第4周时表达开始增强，在第6周时均达到高峰，第8周时表达开始衰减，Bcl-2、Bax基因表达呈时间依赖性变化，hMSCs经诱导后随心肌样细胞特征的表达膜静息电位、去极化幅值和去极化速率逐渐增高。

Our results shown: Compared with those of the unradiated rats, the number of S-100 protein immunoreactive positive glial cells in the brains of the irradiated rats increased gradually. More S-100-positive glial cells with multiple long processes and hypertrophic cell bodies were also observed in these areas.

在此基础上，又做了同一照射剂量（20Gy）照射大鼠半脑后不同存活期间（id，7d；14d，Zld，28d）大鼠全脑S－100动态变化的观察，发现其规律如下：在上述时间点大鼠脑内各部位卜刁m蛋白免疫反应细胞数量进行性增加，伴有 S－100免疫阳性细胞的胞体逐渐增大和交起增多，与正常对照组具有明显的差异。

Results There were no sinificant difference in incidence of aneuploid and highs synithesis phase fraction, the size and distribution of AgNOR between unrecurrent and recurrent tumors, and there were sinificant difference between benign and malignant tumors, and there were singnificant differenct in the number and shape of AgNOR between the groups, and a linear positive correlation was observed between that obvious positive correlation was observed between highs SPF and number of AgNOR.

结果 异倍体率，高S期细胞比率率，AgNOR大小和分布在无复发与复发组间无显著差异，而良性与恶性肿瘤间有显著差异；AgNOR数目和形态各组间有显著差异；高SPF率与AgNOR均能反映其细胞增殖活性。

2.2 转基因拟南芥的筛选选择培育后获得转基因拟南芥植株。从其叶片中提取微量DNA， PCR鉴定，可扩增出750 bp左右片段（图3），表明3G1MHpCAMBIA2301基因已整合到拟南芥染色体中。

Meanwhile, positive human sera of HCV challenged vaccina ted monkeys after 6 weeks immunized, ALT value rose transiently in monkeys vacci nated by PCX. It was positive in monitoring RNA of HCV using RT-PCR in monkey s era.

同时，在免疫后6周用人HCV阳性血清攻击猴子，免疫PCX的猴子出现一过性ALT升高，在攻击后三周内用 RT－PCR检测到猴血清内HCV的RNA阳性。

Meanwhile, positive human sera of HCV challenged vaccina ted monkeys after 6 weeks immunized, ALT value rose transiently in monkeys vacci nated by PCX. It was positive in monitoring RNA of HCV using RT-PCR in monkey s era. The result demonstrated that Rhesus monkey immunized by multi-epitope PCX could elicit high-level immune responses.

近年来，由于多表位抗原概念的兴起，在针对EB，HIV等病毒感染的疫苗研究中引入了多表位抗原疫苗［门，这种思路使对HCV疫苗的研究有了新的切入点，F.r.i［'］等用 HCV.H77株 E蛋白的多个表位所制备的兔血清与HCV
