Both of them showed no toxic effect on mice at the testing dose of 10 mg/kg. The 2,2-diphenyl-1-picrylhydrazyl free radical scavenging test showed that both of the formicary extracts were potent radical scavengers and their scavenging activities were dose-dependent. Furthermore, at higher concentrations (5～10 mg/ml) both of them exhibited significantly higher DPPH scavenging activity than butylated hydroxytoluene.

In order to investigate the antioxidant activity, thirteen stilbene derivatives was examined by DPPH method. The radical scavenging ability is greatly increased by 2, 5-dihydroxy groups in the skeleton. There is a linear relationship between the maximum UV absorption wavelength and the radical scavenging ability of the compounds.

为了考察羟基衍生物的抗氧化活性，应用DPPH法对13个茋类化合物进行自由基清除能力评价。2，5-二羟基取代茋衍生物显示出较强的自由基清除能力，8个非氮杂茋衍生物的最大紫外吸收波长与自由基清除能力之间呈线性相关性。

Take DPPH··ethanol solution as the oxidant system to research on the DPPH··scavenging capacity of the liquid fermented vinegar from north fruits like hawthorn, apple, tangerine, beach jujube, kiwi fruit, pear, mulberry, persimmon, medlar, kernel-apricot etc. and grains like corn, sorghum, millet, wheat, buckwheat, Job"s-tears, purple rice etc. it was found that the scavenging effect on DPPH··of the grain vinegar and fruit vinegar after brewing and sterilization was significantly higher than that of their corresponding vinasse, and With the increase of addition, scavenging rate is gradually increased. To most fruit vinegar and grain vinegar, the scavenging effect on DPPH··are stronger than acetate, and acetic acid has some effective but is not functional, consequently it"s other ingredients that really played scavenging effect in the fermentation of vinegar.

本实验采用DPPH··乙醇溶液为氧化体系，研究北方产山楂、苹果、蜜橘、滩枣、猕猴桃、酥梨、桑椹、水柿、枸杞、仁用杏等数十种果品，以及玉米、高粱、小米、小麦、荞麦、薏米、黑米等数十种粮食作物为原料的液态发酵醋对自由基DPPH··的清除能力，结果发现经过酿造杀菌后的成品果醋及粮食醋对DPPH··的清除作用明显高于其相对应的酒醪；并且随着加入量的增加其清除率也逐渐增高，其中大多数果醋及粮食醋对DPPH··的清除作用均强于醋酸，发现醋酸对DPPH··虽然有一定的清除率但是作用不大，因此说明真正对DPPH··起到清除作用的还是发酵醋中的其他成分。

The leaf had better scavenging DPPH, reducing power, superoxide anion and H2O2 radical than other parts of Morus alba.

至於在特定自由基的清除能力上，桑枝有较佳的氢氧自由基清除能力，桑叶则对超氧阴离子及过氧化氢有较佳的清除能力。

Result Extracts of Myrtus communis Linn.leaves not only effectively scavenged O2(superscript -), O H,DPPH and ONOO(superscript -), but reduced or prevented DNA oxidative damage caused by OH and inhibited lipided pexoxidation.

香桃木叶的非精油组分3种提取物均能有效清除O2、OH、DPPH和ONOO，减轻或消除OH对DNA的氧化损伤，抑制脂质过氧化，其中甲醇－水提取物清除O2和ONOO能力最强，乙酸乙酯提取物清除OH和DPPH的效果最佳。

For N0 neck patients with supraglottic cancer, comprehensive neck dissection is not invariably performed to avoid overtreatment.

对于颈部N0患者不应一律行颈淋巴结清除术；上颈淋巴结清除术作为诊断措施，效果肯定，可避免不必要的全颈淋巴结清除术。

The results show that the three kinds of sulfated fucans all had significant scavenging effects on free radicals.

结 果显示：(1)三种岩藻聚糖硫酸酯组分均有清除活性氧自由基的能力，但清除超氧阴离子自由基的能力高于清除羟基自由基的能力。

Objective To investigate the safety and efficacy of autotransfusion in therapy in hemorrhagic shock with ectopic pregnancies by abdominoscope.Methods We choice forty-two ectopic pregnancies or corpus luteum rupture with hemorrhagic shock into two sets: haematomas of ectopic pregnancies and corpus luteum rupture had been scavenged and haemostasised in laparoscopic approaching;And the others using AutologTM Autotransfusion System in the same time.The blood was collected from operative area and celom,and transfused back to the patiants after the same treatment.

目的 研究自体血液回输在腹腔镜下宫外孕失血性休克治疗中的安全性和效果方法选择42例宫外孕或黄体破裂，失血性休克患者行腹腔镜探查，血肿清除并止血术，随机分成两组：组腹腔镜下直接清除血肿；另外一组在腹腔镜下清除血肿时，应用AutologTM Autotransfusion System，收集手术野和体腔内的出血、积血，处理后回输给患者。

Amount of total phenolic compounds, total flavones and DPPH scavenging activity for different kinds of vinegars were compared. The results indicate that (1) DPPH scavenging activity of different kinds of vinegars has a positive correlation with amount of total phenolic compounds, total flavones, the correlation coefficients were 0.9523 and 0.8691, respectively,(2) the higher content of phenolic compounds and flavones in Zhenjiang aromatic vinegar respond for its higher scavenging activity.
