联甲苯胺

Using 9 fluorenylmethylchloroformate as a pre column derivatising agent, nine aromatic amines ( o toluidine, 4 chloro o toluidine, aniline, 2,4,5 trimethylaniline, p cresidine, p chloroaniline, 4 aminodiphenyl, o anisidine, 2 naphthylamine,) are separated and a quantitative analysis method is studied by means of RP HPLC.

以氯甲酸 9 芴基甲酯为柱前衍生试剂，对 9种单环芳香胺(邻甲苯胺、4 氯邻甲苯胺、苯胺、2 ，4 ，5 三甲基苯胺、3 氨基对甲苯甲醚、对氯苯胺、4 氨基联苯、邻氨基苯甲醚、2 萘胺)进行了高效液相色谱分离和定量分析方法研究。

Racemic backbones 2-amino-2'-hydroxy-6,6'-dimethyl-l,l'-biphenyl la and 2-amino-2'-hydroxy-4,4',6,6'-tetramethyl-l,1'-biphenyl 1b were synthesized from o-methylaniline and 2,4-dimethylaniline via nitration, diazotation/iodination, Ullmann coupling, selective reduction, diazotation/hydrolysis and hydrogenation.

从邻甲苯胺及2，4-二甲基苯胺出发，经过硝化，重氮化-碘代，偶联，单还原，重氮化-水解及还原反应合成了消旋体骨架2-氨基-2'-羟基-6，6'-二甲基-1，1'-联苯1a和2-氨基-2'-羟基-4，4'，6，6'-四甲基-1，1'-联苯1b。

Methods Tarry stools from 38 cases definited upper gastrointestinal bleeding and 16 stomach strains confirmed including red blood cells by test under microscope respectively tested by colloidal gold indicator paper, orthotolidine method and tetramethyl benzidine indicator paper.

将38例临床确诊为上消化道出血患者的&柏油&样粪便和16份经镜检证实含红细胞的胃引流物标本分别用胶体金试纸、邻联甲苯胺和四甲基联苯胺尿隐血试纸测试其是否含有隐血。

In this paper,pyromellitic dianhydride,1,2,3,4-cyclobutanetetracarboxylic dianhydride,4[(4-aminophenyl)-bis(4-methoxyphenyl)methyl]benzeneamine,4-hexyloxy-biphenyl-3′,5′-diaminobenzoate,and additive ADD-34 were used to synthesize four PIs.

文章用均苯四甲酸二酐，4[(4-氨基苯基)-二(4-甲氧基苯基)甲基]苯胺，1，2，3，4-环丁烷四羧酸二酐，4-己烷氧基联苯酚-3′，5′-二胺基苯甲酸酯和不同含量的添加剂制备了聚酰亚胺液晶取向剂。

Results In 38 cases of tarry stools,the positive percentage is 60.5 by colloidal gold indicator paper,and the positive percentage is100 byorthotolidine method and tetramethyl benzidine indicator paper.In 16 cases of stomach strains the positive percentage is respectively 68.8,100 and 81.3 by above three methods.

结果：测试38例&柏油&样粪便标本，胶体金试纸阳性率为60.5％，邻联甲苯胺和尿隐血试纸均为100％；测试16份含红细胞的胃引流物标本，胶体金试纸阳性率为68.8％，邻联甲苯胺为100％，尿隐血试为81.3％。

Methods Three serologic methods including domestic-made enzyme-linked immunosorbent assay reagents, the toluidine red unheated-serum test and treponema pallidum particle agglutination test reagents were compared. The transudate fluid of the syphilis patient in genital duct was detected by polymerase chain reaction for analysis of infectivity.

采用国产酶联免疫吸附试验试剂与甲苯胺红不加热血清试验和梅毒螺旋体颗粒凝集试验进行血清学方法比较，采用聚合酶链反应对梅毒患者生殖道皮损渗出液进行检测，分析其传染性。

Objective To compare characteristics of treponema pallidum antibody screening method with the toluidine red unheated serum test, the enzyme-linked immunosorbent assay and the T.

目的比较无偿献血者梅毒抗体筛查方法甲苯胺红不加热血清试验、双抗原夹心法的酶联免疫吸附试验和梅毒螺旋体明胶凝集试验的特性。

Methods 34933 serum samples were screened by ELISA method on Treponema pallidum antibody. The samples with probable positive result were retested by toluidine red unheated serum test and Treponema pallidum particle assay. Results There were 559 serum samples with probable positive result.

对34933例标本采用酶联免疫吸附试验进行梅毒螺旋体的初筛，初筛结果为可疑阳性的样本进行梅毒螺旋体明胶凝集试验和甲苯胺红不加热血清反应素试验的检测。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
