变性作用

It "denatures" protein molecules, so that their amino-acid chains unfold and digestive enzymes can attack them more easily.

它使蛋白质分子变性，这样它们的氨基酸链展开了并且更容易被消化酶起作用。

The nitrocellulose filter s are then placed on wet filter paper containing alkali, which denatures the DNA

再将硝酸纤维素滤膜置于含碱的湿滤纸上，碱的作用是使DNA变性。

In patients with RP, the concentration of VEGF-A in aqueous humors is lower than in non-RP subjects.

缺乏VEGF-A的促血管生成作用，可能会解释RP的某些临床表现，比如视网膜血管的狭窄和纤维化变性。

Compound Danshen Injection combined with Anisodamine can improve microcirculation cooperatively. Using the combined therapy to treat IgAN patients of this type can improve hypercogulabity state, hemorhelogy and microcirculation disorders. The combined therapy can reduce the excreation of urinary erythrocyte and protein, and decrease serum IgA. The curative effects of the combined therapy overmatches using western medicine of control group.

复方丹参联合654-2在改善微循环方面具有协同作用，用于治疗以血尿为主要表现的IgAN能有效改善患者的高凝高粘状态、血液流变性异常及微循环障碍，明显减少尿红细胞及尿蛋白的排泄，降低血清IgA水平，在一定程度上优于对照组西药的疗效。

ER stress is commonly associated with degenerative pathologies, but its role in disease progression is still a matter for debate.

ER应激通常与变性病理过程有关，然而其在疾病进程中的作用仍然有争议。

Therefore, one of the focuses on AD researches is to determine the causes of the mild cognitive impairment that usually presages the insidious onset of clinical dementia.

一些研究还表明，在AD出现神经变性前的早期记忆功能障碍中，可溶性Aβ已经发挥了重要作用。

Eye is one of the main target organs of microwave. Microwave has effects on visual system primarily involving cornea, lens and retina.

眼睛是微波作用于人体的一个重要靶器官，微波对眼睛的损伤涉及角膜、晶体、视网膜等，它可造成晶状体混浊，视网膜神经元变性、坏死。

This nonmutagenic amino compound 4 (via the investigation into Salmonella/mammalian microsome assay) was also employed as diazo moiety coupling with acet-J-acid to form a diazo acid dye 5. The new dye 5 can color wool at 2% or silk at 3% o. w. f. into black one. The investigation of the uptake of 5 and its color appearance showed that it was assigned to an acid bluish black dye and its blackness was more excellent than that of Acid Black 10B.

经过Salmonella／mammalian microsome assay测试，4表现为非诱变性，用4与乙醯J－酸作用得到新型双偶氮酸性染料（5）。5对羊毛和丝绸分别在2%与3%色度下浸染都得到黑色染样，考察了5的上染曲线，并对染样进行了测色研究，发现该染料属於酸性蓝黑染料，其黑度优於目前市场上流行的酸性黑10B。

After bleeding sloped, the hemoglobin amount in films or gauzes were measured to determine the hemostatic effect Using a randomized design, one incision in each animal was treated with C-CM membrane, the influence of C-CM film on the growth of bacteria (Staphylococcus aureus ATCC 27853. Escherichia coli ATCC 25922. Monil lia albicans ATCC 14053)were observed in vitro with solid medium. Rusults: It was observed that C-CM membrane had no toxic effects on surrounding tissue and was slowly degraded after implanted into rat leg muscular porch ; The results of hemostatic experiment showed that C-CM film adhered well to incisions.

结果：C-CM膜植入动物肌肉中，周围组织无明显炎症，未发现组织变性和坏死，可在组织内缓慢降解，具有良好的组织相容性，6周后反应接近外科缝合丝线组；止血实验结果发现：C-CM膜组和纱布组的出血时间分别为83.5±9.333s和117±15.9275s，血红蛋白光度吸收值为0.9204±0.7559和1.9764±0.7205，二组比较差异显著(P＜0.05)，说明C-CM膜有一定的止血作用；促进创面愈合实验结果显示：不同时间段C-CM膜组肉芽组织较对照组厚，其中胶原纤维含量亦较多，C-CM膜组的创面愈合时间早于空白对照组，伤口愈合较快；抑菌实验显示C-CM膜对三种菌产生接触性抑制。

In order to find out the main influence factor to the water stability of granite asphalt mixture and make large-scale use of granite aggregate in asphalt pavement possible. dynamic shear rheometer was used to study the rheological properties of asphalt mastics with different granite powders and different filler-asphalt ratios to analyse the interaction ability between different granites and asphalt.

为了找出影响花岗岩沥青混合料水稳定性的主要因素，使花岗岩大规模应用于沥青路面成为可能，从花岗岩沥青胶浆着手，采用动态剪切流变仪，对不同花岗岩石粉、不同粉胶比条件下的沥青胶装进行流变性能的研究，以此分析不同花岗岩与沥青交互作用能力。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.
