Chapter 5 A new method for the simultaneous determination of adenine and guanine in DNA extracts using MEKC with indirect LIF detection was proposed.

第五章建立了一种用于同时测定DNA中腺嘌呤和鸟嘌呤含量的胶束电动色谱—间接激光诱导荧光检测新方法。

Guanine A nitrogenous base found in DNA and RNA. Guanine has a pruine ring structure.

鸟嘌呤：是存在于 DNA 与 RNA 中的一种含氮碱基，具有一个嘌呤环结构。

RokoszAdenine, along with guanine, thymine and cytosine, makes up DNA structures and is responsible for helping the body metabolize energy.

腺嘌呤，随着鸟嘌呤，胸腺嘧啶和胞嘧啶，构成了DNA的结构，并帮助身体能量代谢负责。

The most abundant bases are cytosine, thiamine, and uracil and adenine and guanine.

最丰富的碱基是胞嘧啶，胸腺嘧啶，尿嘧啶，腺嘌呤和鸟嘌呤。

DNA consists of a chain made from four types of nucleotide subunits: adenine, cytosine, guanine, and thymine.

的DNA链组成一个由4种核苷酸亚基：腺嘌呤，胞嘧啶，鸟嘌呤和胸腺嘧啶。

The nucleoside guanosine triphosphate is derived from guanine, and supplies energy for certain enzymecatlyzed metabolic reactions.

鸟嘌呤三磷核苷酸源于鸟嘌呤，它在代谢反应中为某些酶提供能量。

The contents of uracil, hypoxanthine and xanthine were firstly determined in 5 species, blast-fried Whitmania pigra, Whitmania pigra from different places by HPLC.

首次对该类药材中的尿嘧啶、次黄嘌呤和黄嘌呤进行了HPLC定量分析，结果表明，种间这3种化合物的含量有明显差异。

Hypoxanthine and a uricase inhibitor were combined into the model drug to work out the rat＇s animal model for hyperuricemia. A comparison was made between the effect of hypoxanthine and that of the model drug on the subject＇s serum uric acid levels. Also, such factors as the dose effect and time effect of the model-building drug were investigated.

采取合用次黄嘌呤和尿酸酶抑制剂为模型药物，制备一种尿酸生成增多型大鼠高尿酸血症动物模型，比较了单用次黄嘌呤及合用尿酸酶抑制剂对受试动物血清尿酸水平的影响，并对造模药物的量效、时效关系等因素进行了考察。

Objective:To study the hypoxanthine phosphoribosyl transferase gene mutation of rat peripheral blood lymphocytes and spleen lymphocytes induced by intermal radiation and of human peripheral blood lymphocytes induced by Y -ray.

目的：本实验主要是用克隆法研究放射性核素内照射诱发Wistar大鼠外周血淋巴细胞和脾淋巴细胞次黄嘌呤鸟嘌呤磷酸核糖转移酶基因突变及γ射线外照射诱发健康成年人外周血淋巴细胞HPRT基因突变情况。

The Ca〓 oscillations occured before GVBD were associated with the resumption of GVBD, because when the oocyte was cultured in medium with hypoxanthine, no Ca〓 oscillation occurred, without hypoxanthine the oscillations occured again.

这些Ca〓波动与卵母细胞的GVBD有关，被次黄嘌呤抑制于GV阶段的卵母细胞不出现这种形式的波动，当再次培养于无次黄嘌呤的培养液中则又出现Ca〓的波动。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
