The method uses CCl4 revulsive small rat liver injures a model, medicaments is preventive experiment, through determining transaminase of serum cereal third , millet straw and liver organization third 2 aldehyde content, yellow purine oxidizes peptide of pleasant of Guang of enzymatic, cereal is reductive enzymatic active and liver tectology change are index, observation grackle extracts the protective effect that content injures to liver.

方法采用CCl4诱导小鼠肝损伤模型，药物预防性实验，通过测定血清谷丙转氨酶、谷草转氨酶和肝组织丙二醛含量、黄嘌呤氧化酶、谷胱甘肽还原酶活性以及肝组织形态学变化为指标，观察白头翁提取物对肝损伤的保护功能。

The research was conducted to observe the effect of hypoxanthine and a uricase inhibitor on the rat＇s serum uric acid levels in order to establish a new, experimental pathological model of the rat＇s gout.

目的：观察次黄嘌呤、尿酸酶抑制剂对大鼠血清尿酸水平的影响，拟建立一种新型实验性大鼠痛风病理模型。

AIM To determine the optimal doses of hypoxanthine and uricase inhibitor oxonic acid potassium salt for establishment of hyperuricemia rat model, and provide experimental evidence to prepare continual hyperuricemia and gout animal model.

目的 确定次黄嘌呤与尿酸酶抑制剂氧嗪酸钾伍用制备高尿酸血症大鼠模型的合适剂量，为制备持续性高尿酸血症及痛风大鼠模型提供实验依据。

Results Hypoxanthine was administered via stomach, while unease inhibitor was injected subcutaneously by lanolin mixed with olefin, which made the uric acid in serum higher than control group about 12 hours.

结果 采用灌胃给予次黄嘌呤，皮下注射以羊毛脂石蜡油为溶剂配制的尿酸酶抑制剂，可使受试动物血尿酸值明显高于空白对照组(P.01)，且可维持12h。

Objective: To study the inhibitory effect of rosmarinic acid on xanthine oxidase.

目的：研究迷迭香酸对黄嘌呤氧化酶的抑制作用。

Xanthine oxidase is an enzyme involved in the production of uric acid.

黄嘌呤氧化酶是一种与尿酸生成相关的酶。

Fulvic acid is able to affect 〓 activity of xanthine oxidase which plays an important role in the production of reactive oxygen in pathological condition.

黄腐酸能够影响黄嘌呤氧化酶的活性，后者可在病理过程中产生活性氧自由基。

Esculetin had the highest affinity toward the binding site of XO, and this was due to hydrogen bonding interactions. The hydroxyl group at C-6 formed hydrogen bonds with the carboxyl group Glu802 that played critical role on XO binding.

在8种香豆素衍生物中发现esculetin与黄嘌呤氧化酶的亲和力最高，因为在esculetin的结构上，C-6的OH基团可与麸胺酸802的COOH基团形成氢键，此键结对於抑制黄嘌伶氧化酶活性是很重要的，因而增加了两者结合的稳定性。

The present doctoral dissertation was carried out to study the chemical constituents isolated from stems of two medicinal schisandraceous plants.34 compounds were isolated from the ethanol extracts of the stems S.henryi collected in the Jiangxi province by various column chromatographies.27 of them were identified on the basis of spectral analysis.There are 18 lignans,(including 5 dibenzocyclooctadienes,6 aryltetralins,2 tetrahydrofurans,3 diarylbutanes,2 other lignans),3 flavanols,2 glyceroesters,1 naphthoquinone,1 xanthine and 2 steroids,of which 6 compounds were new compounds,and 7 compounds were isolated from this family for the first time.

采用多种色谱技术进行分离纯化，从翼梗五味子藤茎的乙醇提取物中分离到34个化合物，综合运用现代波谱学技术鉴定了27个化合物，包括木脂素类化合物18个(其中联苯环辛烯类木脂素5个，芳基四氢萘类木脂素6个，四氢呋喃类木脂素2个，二芳基丁烷类3个，其他类型木脂素2个)，黄烷醇类化合物3个，甘油酯类化合物2个，萘醌类化合物1个，黄嘌呤类化合物1个，甾体类化合物2个，其中，5个为新化合物，7个为本科首次报道。

A yellowish-white, crystalline purine base, C5H4N4O2, that is a precursor of uric acid and is found in blood, urine, muscle tissue, and certain plants.

黄嘌呤一种黄白色结晶的嘌呤硷，c5h4n4o2，它是尿酸的前身，常见于血液、尿液、肌肉组织和某些植物中

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。
