Mechanical and cold allodynia were observed at preadministration and 15, 30, 60, 90, 120, 150, and 180 min after drug administration and were quantified by measuring withdrawal frequencies to stimuli with von Frey filaments and 100% acetone, respectively.

于给药前、给药后15、30、60、90、120、150、180分钟记录机械和冷异常，且经常用 von frey 细丝和100％丙酮分别刺激量化测量停药后反应。

In the medium of HAc-NaAc, Th~(4+) canbe combined with HTTA to form a comparatively steady ternary chelate whichwill be adsorbed and preconcentrated on the mercury electrode and determined bycathodic stripping voltammetry.

在HAc-NaAc介质中钍离子Th~(4+和噻吩甲酰三氟丙酮形成较稳定的三元络合物，先吸附富集在悬汞电极上，后采用阴极溶出伏安法检测痕量钍。

According to the result showed at 280nm and at 490nm,in the comparison of whether protein absorption top and sugar quantity top overlapped,glycoproteins would be detected preparatorily,and as a result,tubes in two distinct areas had glycoproteins by this method. Proteins were precipitated with trichloroaceticacid and with cold acetone,and glycoprotein was determined from SDS-gel.

再从各收集管的收集液中，用三氯乙酸沉淀蛋白法、冷丙酮沉淀蛋白法相结合浓缩、制备蛋白样品，进行SDS—PAGE，对SDS胶进行PAS糖链染色鉴定糖蛋白，并从茶树叶分级蛋白中准确地鉴定出两个区域的收集管中含有多种糖蛋白。

At least half of patients with X-ALD are adults with somewhat milder manifestations, and women who are carriers may become symptomatic. X-ALD is often misdiagnosed as attention-deficit/hyperactivity disorder in boys and as multiple sclerosis in men and women, and is not an uncommon cause of Addison disease;(2) the incidence of X-ALD, estimated to be 1:17 000 in all ethnic groups, approximates that of phenylketonuria;(3) noninvasive and presymptomatic diagnosis and prenatal diagnosis are available; family screening and genetic counseling are key to disease prevention; and (4) new therapies, applied early, show promise.

至少1半的X-ALD为成年病人，表现较轻，而作为携带者的女性也可发病。X-ALD在男孩常误诊为注意缺陷/多动综合征，男女可误诊为多发性硬化，并且也是Addison病的病因；(2)据估计X-ALD发病率为1：17 000，类似于苯丙酮尿症；(3)可进行无创性、症状前诊断和产前诊断；家系筛查和遗传咨询是疾病预防的关键；(4)早期采用新的治疗方法非常具有前景。

Ethel ether, propanone and methyl alcohol were used for the separation of sample, BRUKER VECTOR33 FTIR spectrometer was used for test. The infrared spectrums are analyzed, the qualitative and quantitative analyses of the components are shown and the function of every composition is explained.

分别采用乙醚、丙酮、甲醇等有机溶剂对样品进行分离处理，通过BRUKER VECTOR33傅里叶变换红外光谱仪进行测试，对分离后各组份的红外光谱特征进行解析，给出样品的定性和定量分析结果；对各组份在清洗剂产品中的功能进行了分析说明。

With the analysis and discussion of their photoini- liability, it was indicated that their max are all around 330 nm, and all of them have excellent solubility in water and good photoinitiability. Furthermore, the three Photoinitiators with α-tert-amine are obviously superior to the one with just α-sec-amine. Among the four photoinitiators l-(4-aminophenyl)-2-diethylamino-l- propanone dihydrochloride is the best and it has excellent use value.

通过对它们的光引发性能测试和构效关系的分析探讨，表明四种光引发剂的最大吸收波长λ_(max均在330nm左右，具有优异的水溶性和良好的光引发性能，其中具有α-叔胺基团的三种光引发剂明显优于具有α-仲胺基团的光引发剂，尤其以1-(4-氨基苯基)-2-二乙胺基-1-丙酮盐酸盐的光引发性能最好，具有推广应用前景。

And Pharaoh spoke to Joseph, saying, Your father and your brothers have come to you.
