In order to explore the mechanism of the resistance to cucumber damping-off induced by plant growth-promoting rhizobacteria CH1, the physiological and biochemical method was employed to study the changes in activities of Phenylalanine ammonia-lyase, Polyphenol oxidase and contents of ferulic acid, chlorogenic acid, lignin, phenolic compound and flavonoid of phenolic metabolism in cucumber roots pretreated with plant growth-promoting rhizobacteria CH1 and infected by Pythium aphanidermatum.

为研究植物生长促生细菌CH1诱导黄瓜对猝倒病的抗性的作用机制，采用生理生化的方法，测定了黄瓜根部酚类物质代谢中苯丙氨酸解氨酶、多酚氧化酶活性动态及阿魏酸、绿原酸、木质素、总酚、类黄酮含量变化。

Methods A randomized controlled trail was carried out in 41 patients. The medication design was based on the findings that the half life time of salvianolate was less than 2 h and its time of clearance uas 12 h. The treatment group (n=20) was treated with salvianolate at the dose of 200 mg, intravenous drip, twice a day, and the control group (n=21) with salvianolate at the dose of 200 mg, intravenous drip, once a day. The curative effects of salvianolate on angina pectoris (with syndrome of heart-blood obstruction) in the two groups was compared.

根据丹参酚酸B在体内半衰期小于2h，12h内药物基本从体内消除的研究结果设计给药方案，采用随机对照的方法，试验组（20例）丹参多酚酸盐200mg，静脉滴注，每日2次，对照组（21例）丹参多酚酸盐200mg，每天l次，比较两种给药方法对冠心病心绞痛的疗效差别。

Objective:There are many methods to test the activity of superoxide dismutase.In our country,the method of pyrogallol self-oxidation was used.Two kinds of this method,one is classical method known as 420 nm method;the other is improved micromethod known as 325 nm method.

目的 ：超氧化物歧化酶的测活方法很多，目前国内多采用连苯三酚自氧化法，本方法有两种，一种是经典的Marklund连苯三酚自氧化法，简称 42 0nm法；另一种是对 42 0nm法作了改进的微量连苯三酚自氧化法，简称 32 5nm法。

The properties of environment in which the probe molecule located were estimated properly by the ratio of emission intensity of naphthol and phenol anion peak wave-length in the fluorescence spectra of these compounds.

通过对萘酚基在不同条件下荧光光谱中存在着不同比例的萘酚基和酚负离子发光，可对化合物分子所处环境的特性作出正确的估计。

In this paper, concentration of 300mg/L Naphthol Green-B dyes was used to be treated by white rot fungi. At first, the strain of pc5305 was to be screened for the best decolorization white rot fungus which used to treat Naphthol Green-B from the four different strains.

本文以300mg/L的萘酚绿-B染料为处理对象，首先从四种不同白腐菌中筛选出对萘酚绿-B具最佳脱色作用的pc5305，并对pc5305脱色萘酚绿-B的条件进行了优化。

Inhibition to activated sludge process by 2-naphthol was also investigated by Warburg respirometer to verify the conclusion drawn from Rank Cell respirometer test. 2-Naphthol in low concentration was biodegradable, hence resulted in the acceleration of respiration, while in higher concentration 2-naphthol would dramatically inhibit microorganisms respiration on account of high K〓 and electron density.

用Warburg呼吸仪研究了2-萘酚对活性污泥过程的抑制作用，验证了RankCell呼吸仪的研究结论，发现低浓度下2-萘酚自身能被生物降解而使活性污泥中微生物呼吸速率升高；浓度增加后2-萘酚因良好的脂溶性和强亲核能力而对活性污泥过程产生强抑制。

Methods The effects of various concentrations of tea polyphenols on proliferation, invasion and apoptosis of CGTH W-3 cells were observed by MTF assay, plate scarification assay and flow cytometer, respectively.

方法用MTT法检测细胞增殖活性，观察不同浓度茶多酚对CGTH W-3细胞增殖活性的影响；并通过培养板划痕法观察茶多酚对CGTH W-3细胞侵袭能力的影响；应用流式细胞仪检测各浓度茶多酚诱导CGTH W-3细胞凋亡的作用。

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.

对不同品种食醋总酚含量、总黄酮含量、DPPH自由基清除活性的比较分析表明：(1)不同品种食醋自由基清除活性与醋中的总酚含量、总黄酮含量存在正相关性，相关系数分别为0.9523、0.8691；(2)镇江香醋中由于总酚含量、总黄酮含量较高因而自由基清除作用较强。

The gassypol was extracted from cotton root bark by the method of diethyl ether.
