特异性

The RT-PCR was sensitive and specific for HEV and did not amplify closely related bovine coronavirus and pseudorabies virus of pigs.

检测与HEV亲缘性较高的牛冠状病毒及猪的伪狂犬病毒均为阴性，最低可以检测到10个TCID50/100μl的病毒，说明该方法的有较好的特异性和敏感性。

Objective Investigation was precced in rodent's Yesinia in plague focus and non-plague focus fo Guangdong,to understand the circumstance that the distrbution of Yersinla,and whether the restrained phenomenon of yersinia was existed. Meth-ods IHA and RIP was used for surveying the particular FI Ab of yersinia pestis.Yersinia pestis were surveyed by plague culture me-dia.The contents of ileocecal part,the liver,the spleen and the tongue of rodent's were put into PBS that were propagated（4℃）for3weeks,then the above PBS liquid was smeared on selective culture media to sarvey yersina enterocolitica and Yersina pseudotuberculosis etc.

目的 了解广东省鼠疫疫源地和非鼠疫疫源地鼠类耶尔森氏菌的分布和相互抑制的情况方法分别采用间接血球凝集试验、放射免疫沉淀试验进行鼠疫耶尔森氏菌特异性F1抗体检测，并分别对鼠类回盲部内容物和肝、脾、舌进行冷增菌后，以选择培养基分离。

分别采用间接血球凝集试验、放射免疫沉淀试验进行鼠疫耶尔森氏菌特异性f1抗体检测，并分别对鼠类回盲部内容物和肝、脾、舌进行冷增菌后，以选择培养基分离。

The 16S rRNA sequences of the bacterial endosymbionts from five geographic populations of two psocid species, Liposcelis bostrychophila and L. decolor was analyzed.

采用特异性引物PCR扩增、克隆和测序获得嗜卷书虱和无色书虱共5个地理种群体内共生菌16S rRNA基因序列。

AIM: To investigate the effect of pyrrolidine dithiocarbamate, a specific inhibitor of NF-κB on the proliferation and apoptosis of K562 cells and to explore the anti-tumor mechanism of PDTC.

目的：观察核转录因子NF-κB活性特异性抑制剂PDTC（吡咯烷二硫代氨基甲酸盐）对急性白血病细胞系K562细胞增殖的影响，并探讨其机制。

Objective To study the value of the product of voltage and duration of QRS in diagnosing the left ventricular hypertrophy in primary hypertension.

内容摘要：目的探讨QRS电压与时间乘积诊断高血压、左室肥厚的敏感性、特异性及准确性。

Because there were many occasional species in the desert and the distribution of many species were dependent largely on the habitat, the paper concluded that neither the methods of sampling line and nest method for all species nor the sampling method of the pattern of plum blossom quadrat for the herbaceous species could be suitable for observation in the desert.

由于沙漠物种偶见种多，频度和密度较低，并且分布的环境特异性强，认为对沙漠植物群落观测，样线法、巢式样方法以及对草本观测的梅花样方法均具有一定局限性，建议对草本和灌木物种多样性观测，在确定合理的布样方向基础上，以4m 4m为基本样方。

Presented in this article is a report of synchronous determination of acetylcholinesterase and butyrylcholinesterase in finger blood established on the basis of the regression equation (Y = 0.149 8X+22.483 5) where hemoglobin is highly correlated with hematocrit (r = 0.999 2, P.001), with quinidine sulphate as the specific inhibitor of BChE.

本文根据全血的血红蛋白含量与红细胞压积容量的高度相关性的回归方程式(Y=0.149 8X+22.4835)，以及用硫酸奎尼丁作为丁酰胆碱酯酶的特异性抑制剂，建立了指血乙酰胆碱酯酶和BChE活性的同步测定法。

Western blotting analysis revealed that the recombinant protein could react with rabbit anti-African swine fever virus VP73 polyclonal antibody. Fusion expression of African swine fever virus VP73L is helpful to to prepare ASFVserological diagnostic reagent in next work.

所得结果为进一步研究：分离纯化该重组融合蛋白；确证目标抗原蛋白VP73L免疫原性及其特异性，进而达到建立非洲猪瘟病毒的免疫检测方法奠定了必要的材料与技术基础。

Radioautography indicated that there was a radioactive bright point, the binding rate of 125I labeled AMH with tumor cells reached 100％. Conclusions AMH can be served as a specific tumor marker in the diagnosis of difficult and complicated tumors of ovary, and in the diagnosis,treatment and follow-up survey of the early GCT.

AMH可作为一种特异性的肿瘤标记物；可用于卵巢疑难肿瘤的鉴别诊断以及早期卵巢GCT的诊断；有可能成为卵巢GCT治疗和随访的观察指标。
