查询词典 urease

Methods: 90 patients with upper digestive tract discomfort were endoscopied and the status of H-pylori was detected by histodiagnosis, mucous smear staining and rapid urease test, as well as by 14C-UBT.

Therewas a significant characteristic of the vertical distribution of soil enzyme activity,the relationship analysis indicated that there was a significant positive relationshipbetween the catalase activity and OM,and total N,and effective P、K,and ex-changible Mg,there was a negative relationship between the catalase activity andBase Situatiou percentage,and Total Contents of Base;the activity of the polyphe-nol oxidase was positively related with OM,and negatively related with total N andexchangible Ca clearly;The urease activity decreased with CPR increasing,and thechange of the former two kinds of soil enzyme actirity was not significantly withCPR increasing,It is possible to be related with maned disturbance frequently.

随着代次增加，有机质和交换性Ca下降明显；土壤的CEC和交换性酸分别下降了8.8—16.1%和6.8—18.5%，因此，其养分总量亦逐代降低，其中有机质下降幅度最大；土壤酶的活性具有明显的垂直分布特征，相关分析表明，过氧化氢酶活性与土壤OM、全N、有效P、K和交换性Mg有极显著的正相关，而与盐基总量、盐基饱和度呈明显的负相关。多酚氧化酶活性与OM呈显著负相关，与全N、交换性Ca有显著相关。脲酶活性则有随连栽代次增加而有下降趋势，前两种酶在代次之间变化不明显，可能与频繁的土壤干扰有关。

Result indicated that the titer for IgY-Hp was 32 times higher than that for IgY in egg yolk from nonimmunized hens and the titer for Urease was 16 times.

对IgY的耐热、耐酸试验表明：pH对IgY－HP活性的影响和温度有关，温度越高，IgY－HP的耐酸能力越差。

Effects of quinhydrone, as urease inhibitor, on growth, root activities, nitrogen metabolism, photosynthetic character, yield as well as quality were studied under pot experiment with water spanich and plot experiment with B.chinensis Var.comrtzunis. The results were shown as follow: 1. Applying low and medium amount quinhydrone promoted the growth of water spanich and B.chinensis Va,communis, whereas high amount treatment had little effect on water spanich growth, and inhibited the growth of B.chinensis Var communis.

以醌氢醌为脲酶抑制剂，蕹菜和小白菜为试材，研究了不同用量的醌氢醌对这两种蔬菜生长、根系活性、氮代谢、光合特性以及产量、品质的影响，结果表明：1 低、中量醌氢醌能促进蕹菜、小白菜的生长，高量醌氢醌对蕹菜的促进作用不大，对小白菜生长有抑制作用。

The result of canonical correlation analysis showed that there existed a significant canonical correlation between "Integral soil enzyme activity factor" and "Integral soil fertility factor",among the test enzymes, peroxidase,urease, polyphenol oxidase and amylase had great relations with the siol organic matter and total N.

典型相关分析的结果表明&综合土壤酶活性因子&与&综合土壤肥力因子&存在极显著的典型相关关系，其中过氧化物酶、脲酶、多酚氧化酶和淀粉酶与有机质和全氮关系密切。

The results showed that granular urea amended with dicyandiamide and N- thiophosphoric triamide induced the highest soil nitrate-reductase activity, granular urea brought about the highest soil urease activity and microbial biomass C a...

结果表明，施用硝化抑制剂和脲酶抑制剂涂层大颗粒尿素肥料的土壤硝酸还原酶活性最高；施用大颗粒尿素，脲酶活性最强，微生物量碳、氮最高。

Results showed that the activity of soil enzymes was obviously different.Among the different vegetation types,the activity of soil enzymes under Tilia mandshurica forests was the highest except peroxidase,whereas that under shrub-grass was the lowest.The activity of soil urease and alkaline phosphate under shrub was higher than that under the mixed forests.Activity of soil catalase and phosphate under Larix principis-rupprechtii forests was higher than that under Pinus tabulaeformis.

结果表明：不同植被类型的土壤酶活性有显著的区别，其中除过氧化物酶外，糠椴林的土壤酶活性均属最高水平，而灌草丛所有酶活性都属最低水平；灌木丛中脲酶和碱性磷酸酶活性显著高于杂木林；华北落叶松林的磷酸酶和过氧化氢酶活性均高于油松林。
