Object: The purpose of this study was to supply people with scientific dietary instructions by investigating the change of the content of adenine, guanine, xanthine and hypoxanthine in two Huahuang fish and carp during boil processing. Method The HPLC method was accepted.

目的：通过检测经过水煮的黄花鱼和鲤鱼中腺嘌呤、鸟嘌呤、黄嘌呤、次黄嘌呤的含量，探索在高温水煮过程中嘌呤含量的变化，希望以此为人们的健康饮食提供科学的指导基础。

It shows that the allantoin, which only takes little part in calves, was the main part (about73%~88%) in the cattle's urine, and the xanthine and hypoxanthine which are also take only much little part, can be neglected.

结果发现，试验牛尿中嘌呤衍生物中尿囊素大约为73%~88%，黄嘌呤和次黄嘌呤的含量很小，可以忽略不计，与以往对成年反刍动物的研究结果相似，与同个体犊牛期的研究结果相反。

Result:The linear of inosine is 0.040 1～0.721 8 μg,r=0.999 9,the limit of detection is 8.2 ng;The linear of hypoxanthine is 0.050 2～0.903 6 μg,r=0.999 9,the limit of detection is 7.4 ng.Conclusion:The peak ...

结果：肌苷的线性范围为0.040 1~0.721 8μg，r=0.999 9，最低检测限为8.2 ng；次黄嘌呤的线性范围为0.050 2~0.903 6μg，r=0.999 9，最低检测限为7.4ng；结论：各有关物质峰与肌苷峰能达到有效分离，且操作方法简便、准确、稳定，专属性强，可用于肌苷口服溶液有关物质的检查。

The content of purines in soup increased sharply during 10 min, increased slowly during 10 min to 60 min. The content of adenine in carp weighed 200 g increased during boiling process, that of guanine was stable, that of total purines and hypoxanthine decreased. The content of total purines and four purines in Huahuang fish decreased during boil processing.

鱼汤中嘌呤含量在10min内迅速升高，10~60min缓慢升高。200g鲤鱼中腺嘌呤含量在水煮加热过程中升高，鸟嘌呤含量无明显变化，总嘌呤和次黄嘌呤组分含量下降，200g黄花鱼的总嘌呤及4种嘌呤组分含量在水煮加热过程中下降。

A method of screening serum of patients of gout and hyperuricemia includes checking purine compound content of xanthine and hypoxanthine in serum to be tested, confirming that serum to be tested is serum of gout patient if xanthine content of 1.00-2.35 mg / L and / or hypoxanthine content of 4.1-16.00 mg / L are contained in serum to be tested and confirming that serum to be tested is serum of hyperuricemia patient if xanthine content of 0.20-1.20mg/L and / or hypoxanthine content of 1.30-3.50mg/L are contained in serum to be tested.

本发明所提供的筛查痛风疑似患者及高尿酸血症疑似患者血清的方法，是检测待测血清中包括黄嘌呤和次黄嘌呤在内的嘌呤化合物的含量，如待测血清中黄嘌呤含量为1.00-2.35mg/L，和/或次黄嘌呤含量为4.1-16.00mg/L，则待测血清为痛风疑似患者血清；如待测血清中黄嘌呤含量为0.20-1.20mg/L，和/或次黄嘌呤含量为1.30-3.50mg/L，则待测血清为高尿酸血症疑似患者血清。

Objective: Using HPLC To determine hypoxanthine in co-hirudo injection for establishing its HPLC fingerprint, and evaluating its internal quality. Method: The chromatographic separation was performed on a Kromasil C18 column (4.6 mm×250 mm,5 μm).

中文摘要：目的：用高效液相色谱法测定复方水蛭注射液中次黄嘌呤的含量，并建立注射液指纹图谱，全面评价其内在质量。

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。

This class of substances includes caffeine and the related chemical theobromine.

巧克力由可可豆加工而成，含有多种甲基黄嘌呤的衍生物，咖啡因和可可碱就属于这类物质。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
