查询词典 dose

Measurements and Main Results: ATRA stimulated NB4 cells to transmigrate toward the A549 cells in a time- and dose-dependent manner. Replacement of A459 condition medium by its original medium abrogated this transmigration.

测量与结果：全反式维甲酸会刺激 NB4 细胞迁移至 A549 细胞，并且具有时间与剂量之效应，若是以单纯的培养液取代 A549 细胞之条件培养液，则 NB4 不会有迁移的作用。

Experimental mice were exposed to Trypanosome evansi after injection by different doses of antigenic reservoir. The results showed that 20 μg dose produced 83% and 67% protection to 2 sample variations after 4 immunizations. However, 3 immunizing doses could not give good protection. No protective effects were detected when experimental animals immunized by single VSG exposed to isotype from different rabbits.

用不同剂量抗原库免疫小鼠后进行攻虫，结果显示：经四次免疫后，20μg 剂量对随机抽取的两个变异体100 条虫体的保护率分别达到 83%和 67%；改变免疫方法，经三次免疫后的保护效果不理想；用单一 VSG 抗原免疫小鼠，接种来自不同兔体的同型虫体，不能起到相应保护作用。

Children who are tuberculin skin test positive without active disease can be given a daily dose of the antibiotic isoniazid for six months or a combination of isoniazid and rifampicin for three months to prevent infection developing into active disease.

谁是儿童结核菌素试验阳性，没有积极的疾病可以得到每日剂量的抗生素异烟肼6个月或1的组合异烟肼和利福平为三个月，以防止感染发展为活动性疾病。

The results showed that (1) the positive staining of ChAT was obviously observed in the cells of the three kinds of human pituitary adenoma, however, it was lower than that in normal human pituitary gland;(2) ACh had a similar effect on the proliferation of the three kinds of human pituitary adenoma cells. ACh at 0.1～10 μmol/L decreased the ［3H］TdR incorporation and the MTT A value in a dose-dependent manner. At the same time, ACh decreased the ratio of S or G2 phase pituitary adenoma cells significantly, but increased the ratio of G1 phase pituitary tumour cells markedly;(3) the effect of acetylcholine on the proliferation of human pituitary adenoma cells was inhibited by atropine, but not by tubocurarine;(4) ACh had no effect on the apoptosis of human pituitary adenoma cells cultured in vitro.

结果发现：(1)三种垂体腺瘤细胞中均有胆碱酯酶的表达，但明显少于正常垂体；(2)ACh对三种类型的人垂体腺瘤细胞增殖代谢的影响相类似，不同浓度的ACh能明显抑制体外培养的三种人垂体腺瘤细胞的增殖，呈明显的剂量效应关系，同时ACh能减少垂体腺瘤细胞进入S、G2期的细胞比例，而使处于G1期的细胞比例增加；(3)ACh的这种作用可被阿托品阻断，但不受筒箭毒的影响；(4)ACh对体外培养的三种人垂体腺瘤细胞凋亡无明显影响。

Methods: Effect of SKI, a herbal preparation for lowering adverse Qi, despelling turbidness, supplementing Qi and activating circulation, and Benazepril were observed by cultured glomerular mesangial cell technique in vitro.Results: SKI could inhibit the fibronetin, laminin, and type Ⅳ collagen of ECM, and the action was dose-dependent.

Nowadays, most of research are to build a transmutative Petri Nets through adding controlling place sets, controlling arc sets and controlling policy to the basic Petri Nets, while the Controlled Petri Nets could be used to argue many controlling theory problems conveniently and to induce many logically and physically supervisory and solve the Event Feedback Controlling Problems and State Feedback Controlling Problem in DEDS supervisory theory.
