Results Three nucleoside compounds and one lignan compound were isolated from the flower buds of Panax quinquefolium L., their structure were identified as 2′-deoxyuridine, 2′-deoxythymidine,vidarabine and pinoresinol.

结果 分离得到了3个核苷类化合物和1个木脂素类化合物，分别鉴定为脱氧尿苷(2′-deoxyuridine，1)、脱氧胸苷(2′-deoxythymidine，2)、阿糖腺苷(vidarabine，3)和松脂素（pinoresinol，4）。

In accordance with the fact that 5-brom-odeoxyuridinecan incorporate period-ically into the nuclear DNA to substitutethe thymidine in DNA,we devoloped a newbasic fuchsin staining method in which weused BrdU as a chromosomal marker in in situnick translation of chromosomes.

根据5—溴脱氧尿嘧啶核苷可周期性替代DNA链中的胸腺嘧啶核苷而显示不同细胞周期染色体的特性，我们用BrdU作为染色体的标记，首次建立了一种硷性复红染色的染色体原位切口移位的新方法。

Comparison of extracting temperature, solvent type, solvent-mycelial ratio and extracting time in water bath, the optimum extraction condition was determined as follows: immerge the mycelia powder in 5 time volume of 50% ethanol, reeling extraction at 50℃ for 60 minutes.

从不同水浴温度、浸提溶剂、浸提比例和浸提时间对核苷类物质影响的正交试验结果中可以发现，上述各个因素对核苷类物质的提取均有显著的影响。

The development and availability of nucleoside and nucleotide analogues has greatly altered the management of patients with chronic hepatitis B.

On the basis of spectroscopic analysis, they were identified as adenine, adenosine, ura...

根据光谱分析分别鉴定为：腺嘌呤，腺嘌呤核苷，尿嘧啶，尿嘧啶核苷和D-甘露醇等。

It demonstrated that the molecular size matching and the sterically arrangement of groups of studied compounds with nucleoside phosphates are very important for the interaction of them. And the quenching ability depends on the interaction of these species strongly. Evidently, this phenomenon can be used as a method for the molecular recognition of nucleoside phosphate by the changing of fluorescence intensity of these compounds.

实验结果表明，分子尺寸的匹配和化合物中基团的空间合理排布是化合物和核苷磷酸盐间能发生相互作用的重要根据，而猝灭则强烈地依赖于这类物种间的相互作用，因此可利用化合物荧光强度的改变来识别各种不同的核苷磷酸盐。

UCK is able to catalyze phosphorylation of its physiological substrate uridine and cytidine, and it also plays important roles for the phosphorylation of nucleoside analogs that are being investigated for possible use in chemotherapy of cancer, such as 6-azauridine, 5-fluorouridine and so on.

将表达UCK不同丰度的肝癌细胞进行6-氮尿苷的敏感试验显示，6-氮尿苷对UCK表达量较高的HepG2细胞的毒性作用强于对UCK表达量较低的L02细胞，提示UCK有可能成为临床用药的一个参考指标，克隆人类尿苷胞苷激酶对寻找新的嘧啶核苷类似物并研究它们的药理活性有着重要的意义。
