查询词典 the positive

In this study, we investigate the heat-induced inhibition of drug-metabolizing enzyme activity in mice fed with freeze-dried, heated freeze-dried or half amount autolyzed freeze-dried Brussels sprouts powder. 0.5% ethoxyquin diet was fed to another group of mice as a positive control. The study mice, four per group, were fed a diet consisting of 20% Brussels sprouts for 7 days. Each group had its own pair-fed group. We found significantly greater inductions of glutathione S- transferase, quinine reductase, and phase Ⅱ drug-metabolizing enzyme activities in groups fed within freeze-dried and heated freeze-dried Brussels sprouts than their pair-fed groups. These findings indicate that intestinal microflora still can hydrolyze glucosinolates without plant myrosinase activity, though the alteration of cytochrome- P-450 1A (CYP1A, a phase Ⅰ drug-metabolizing enzyme) induction was only 1.4-fold.

本实验欲进一步探討加热处理之抱子甘蓝对phase Ⅰ与phase Ⅱ解毒酵素活性之影响差异，实验分三组，抱子甘蓝(1)冷冻乾燥组（glucosinolate未裂解）(2)加热冷冻乾燥组(3)半量之裂解冷冻乾燥组（glucosinolate已裂解），(4)and 0.5% ethoxyquin diet was used as a positive control以2%重量混合成饲料，餵以小白鼠（4只／组）7天，结果发现，在第(2)组小白鼠GST phase Ⅱ酵素）活性显著上升，显示在植物裂解酵素不存在之状况下，肠胃道之微生物仍可促进裂解反应，但由CYP1A活性增加不显著（仅1.4倍）看来，根据定义：单独phase Ⅱ酵素活性增加，为monofunctional induction/inducer，可加速致癌物之代谢。

The positive expression rates of VEGF: Pien Tze Huang Group,Lentiviruse mediated-KISS-1 Group and Combined therapy Group, the positive expression rates of VEGF was lower than the other two groups.

VEGF阳性表达率：片仔癀组、KISS-1组和联合治疗组，原发灶肿瘤组织VEGF阳性表达率低于空白组和病毒液组；片仔癀组、KISS-1组、联合治疗组之间相比，无显著性差异。

Methods Routine immunization of BALB/ c mice by a tansfected cell line 293T/ B7-H4 as antigens.Then the immunized spleen was fused with SP2/0,a kind of plasmocytoma cells, and screen the positive clones by FCS with the 293T/B7-H4 as a positive control while 293T/ mock as the negative control.

以高表达人B7-H4分子的基因转染细胞株293T/B7-H4为免疫原，常规免疫BALB/c小鼠，采用B淋巴细胞杂交瘤技术进行细胞融合，并以该基因转染细胞293T/B7-H4作为阳性筛选细胞，以转空质粒的对照细胞293T/Mock作为阴性对照细胞。

On the contrary, at the moment γ changes suddenly the pulselike SP change ΔV will always arise no matter the increment Δγ is positive or negative. The positive or negative sign of Δγ gives opposite effect on ΔV.

反之，无论γ的增量Δγ为正值或负值，当γ突变，即对样品进行突然加卸载的时刻则出现了脉冲状自电位信号ΔV，Δγ的正或负对ΔV的影响是相反的。

In this study, we found that the positive immunostaining for αSMA was increased in group DN from week 4 onward, mainly located in dilated tubuli, which was more evident at week 8. The double staining for CTGF and p27kip1 showed that the increased positive staining for both antibodies was more evident in tubuli and some glomeruli.
