方法］应用纸片法和试管稀释法进行体外抑菌试验，测定左氧氟沙星与多黏菌素联合对鸡大肠杆菌、鸡白痢沙门氏菌的抑菌圈大小和最小抑菌浓度。

Methods The plasma NO was measured in 40 elderly patients with CHF by colorimetric analysis and SOD activity by the autoxibation of pyrogallic acid.

方法采用比色分析法和邻苯三酚自氧化法测定了40例老年CHF患者的血浆NO浓度及SOD活性。

It is found that the low dielectric constant inhibits the disproportion of pyrogallic, but it can be settled by increasing the pH or the water content of the reverse microemulsion to obtain a stable generation of the substrate. Then the activity of SOD is determined in such a system and a bell -shaped curve of the activity vs. W〓 is obtained although only subactivity is found. The reasons can be attributed to the low dielectric constant and the attraction of CTA〓.

的介电常数的降低对邻苯三酚的自氧化有抑制作用，因此实验中通过提高CTAB微乳液的表观pH或增大水化度即W〓，最终得到了一定浓度的底物超氧阴离子O〓〓·，保证了SOD活性的测定，并得到了SOD酶活性随含水量变化的&钟形&曲线。

As a solvent, it was mixed with various quantity of pigskin collagen powder. During the dissolution, three kinds of heating methods were applied. The one was be heated in water bath directly, the second one was be heated in water by microwave radialization and the third one was be heated by microwave radialization directly.

通过普通水浴加热，微波辐射水浴加热和微波直接辐射加热三种方式研究了离子液体对胶原蛋白的溶解能力，对不同质量浓度的溶液进行傅里叶变换红外测定，分析溶液中的胶原蛋白结构的变化，最后，对溶液进行再生得到皮胶原蛋白膜，并进行红外分析。

The bioassay results showed that parthenolide had nematicidal activity against tested nematode Bursaphelenchus xylophilus and Panagrellus redivivus, and their death rate at 200 μg/ml within 48 h were 70.4% and 100% respectively.

生物活性测定结果表明小白菊内酯对所测试的松材线虫和全齿复活线虫具有毒杀作用，浓度200μg/ml对两种线虫进行处理，48h的死亡率分别为70.4%和100%。

The dogs were administrated with carboplatin at the dosage of 16.5mg/kg intravenously, intra-arterially or retroperitoneally. The blood samples were taken at 0, 5, 15 minutes, and 0.5, 1, 2, 4, 8, 24 and 72 hours after instillation. The competent platinum concentrations were measured with high-performance liquid chromatography. Then the pharmacokinetic parameters were calculated and analysed.

随机将18只雌性家犬分为3组，分别经静脉，动脉及腹膜后推注卡铂(16.5 mg/kg)，然后于给药后的0、5、15分钟，0.5、1、2、4、8、24、72小时取静脉血，用高效液相色谱法测定血浆活性铂的浓度，计算和比较不同给药方式下卡铂的药代动力学参数。

Make up 40% sugar juice now, using sugar volume and raw material to compare is 1: 0.7, 0.2% citric acid are added in sugar juice, because watermelon skin organization is harder, can appear candy law to heat with boil make, cast the watermelon skin that cent has cut into to boil make, it is OK to begin big a crucial moment heats, make its fast evaporate moisture, boil raw material to become transparent all the time, when sugar juice concentrates ceaselessly and showing syrup, should be to use small fire to undertake heating, lest produce anxious saccharify to make product darkly Brown, determine sugar juice chroma is achieved 70% when should stop to heat.

现配制40%糖液，用糖量与原料比是1：0.7，在糖液中加入0.2%柠檬酸，因西瓜皮组织比较坚硬，可用一次透糖法加热煮制，把分切好的西瓜皮投进一起煮制，开始可以大火候加热，让其快速蒸发水分，一直煮到原料变得透明，糖液不断浓缩而呈糖浆时，应是用小火进行加热，以免产生焦糖化使产品呈黑褐色，测定糖液浓度达到70%时就应停止加热。

The effects of safener on the growth and ALS activity were also examined. It showed that low concentration of AE F107892 could stimulate the growth of s-18 cultivars, but had little effect on the r-6 cultivars. High concentration of AE F107892 could inhibit the growth of both of the two cultivars.

测定了安全剂对小麦生长及ALS活力、GSH含量和GST活性的影响，结果表明：低浓度安全剂刺激敏18号小麦的生长，对抗6号的影响则较小，高浓度则都抑制了小麦幼苗的生长。

The distribution of safflor yellow A in the body is abroad and the speed of its process is swift.

本文建立了反相高效液相色谱法测定小鼠血浆及组织中红花黄色素A的浓度，并对红花黄色素A在小鼠体内的变化过程及分布特征进行初步探讨。

She gently rebuff ed him, but agreed that they could be friends

她婉言拒绝了，但同意作为朋友相处。

If in the penal farm, you were sure to be criticized.
