Result s:10 μmol/L retinoids could inhibit the Bel-7402 proliferation and decrease the colony forming of liver cancer cells on soft agar significantly.So some biochemical markers indicating the proliferation status of liver cancer cells changed significant ly, including the significant activity increase of ornithine carbamyl transferase, tyrosine-α-ketoglutaric transaminase and alkaline phosphatase, the significant decrease α-fetoprotein secretion,γ-glutamyltranspetidase and aldolase activity.

结果：10μmol/L维甲酸显著抑制肝癌细胞增殖，并使肝癌细胞软琼脂集落形成率明显减少，使代表肝细胞分化的酶鸟氨酸氨基甲酰转移酶、酪氨酸-α-酮戊二酸转氨酶和碱性磷酸酶比活力明显升高，甲胎蛋白分泌量、γ-谷氨酰转肽酶和醛缩酶比活力明显下降。

Activaed organic substrate react with carbon dioxide,which can be changed carboxylic acid in the way.

合成了二苯乙二酮缩双苯胺锰的配合物，研究了其对CO2的固定及催化CO2同有机底物反应。

You will convert the carvone to its semicarbazone for use in a polarimetric analysis.

为了作旋光度分析，你将会把香芹酮转变为缩胺基脲。

Because the limonene does not have a carbonyl group, the small amount of it which remainsin the carvone fraction will not form a semicarbazone derivative.

由於柠檬烯没有羧基，留在香芹酮馏份中少量的柠檬烯将不会产生缩胺基脲的衍生物。

The useful and important tests of sensibility are: testing the vibratory sensation with tuning fork, vibrometer testing for vibratory thresholds, von Frey testing (determined by Semmes－ Weinstein nylon monofilaments or Pressure－ Specifying Discriminator) for cutaneous pressure thresholds, measurement of static and moving two－ point discrimination with the Disk－ Criminator, Moberg's ninhydrin test, O'Rain skin wrinkling test, Picking－ up test, Tinel's sign and electrodiagnostic test.

此文对临床上重要且实用的皮肤感觉功能测定方法如音叉皮肤振动觉定性检查、振动觉阈的振动器定量测定、Semmes－Weinstein尼龙单丝或Pressure－SpecifyingDiscri minator行皮肤压觉阈的测定、用Disk－Criminator进行静止和运动的两点辨别觉测定、茚三酮试验、O'Rain指腹皮肤皱缩试验、捡物试验、Tinel's征电生理检查以及这些检查方法在神经断裂、神经卡压及神经损伤或修复后的恢复等情况中的应用和评价作一讨论。

Finally, reacting II with PhNCO givethe compound 1-(6-nitrobenzimidazol-l-acetyl)-4-phenylsemicarbazide,III in the presence of〓 give the new cyclic compound 2-phenylamino-5-(6-nitrobenzimidazol- 1-methylene)-l,3,4-oxadiazole.

第三部分：以6-硝基苯并咪唑-1-乙酰肼为原料，分别与取代苯甲醛、苯乙酮及乙酰基二茂铁进行缩合反应，合成了10个新的6-硝基苯并咪唑-1-乙酰腙衍生物。

Furthermore, the important fragment which is composed of pentenyl cinnamic acid and D-Tyrosine, and the ester which is composed of L-N-methylated phenyl amino acid and diketopiprazine was synthesized with considerable yield The conjugation of the new DOPA analogue into the peptide in the total synthesis of Pepticinnamin E was investigatited

另外，本文作者还进一步合成了高收率的戊烯基肉桂酸衍生物与D-酪氨酸的缩合片段及L-N-甲基苯丙氨酸与哌嗪二酮的酯两个重要的结构组成部分；对新多巴衍生物片段嵌入肽链中的工作亦进行了有益的尝试。

Any monosaccharide sugar that contains a ketone group or its hemiacetal.

任何一种含有酮基或其半缩醛的单糖。

Sugar that contains a ketone group or its hemiacetal.

任何一种含有酮基或其半缩醛的单糖。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""

客人们在卡罗利娜·埃凯家里，举止就文雅一些，因为卡罗利娜的母亲治家很严厉。
