结果 ：从四逆汤水煎剂的乙酸乙酯萃取部分分得 6个化合物，分别鉴定为香草酸(1)，芒柄花素(2 )，异甘草素(3)，甘草素(4)，华良姜素B(5 )和尿嘧啶(6 )。

The results revealed that with the increasing ear of continuous C. sativus cropping soil vanillic acid, p-hydroxyhenzoic acid and ferulic acid accumulated gradually. The total amount of the three phenolic compounds reached 29. 8 mgkg^(-1) dry soil after 7 years cropping, being markedly higher than that after 1 or 3 years cropping. After treated with these compounds, the root length and stem width of C.

结果表明：土壤中香草酸、对羟基苯甲酸及阿魏酸随黄瓜连作年限增加而呈现积累趋势；在连作7年的大棚土壤中3种酚酸类物质总量达29.8mgkg^(-1)干土，显著高于连作1年和1年土壤中的含量；酚酸物质可使黄瓜幼苗根长及茎粗显著降低，使株高及干物质量略有下降。

To clarify the relationships between phenolic compounds and continuous cropping obstacle of Rehmannia glutinosa, the accumulation amounts of ferulic acid, vanillic acid, vanillin, and β-hydroxybenzoic acid in continuously cropped R. glutinosa soil were measured, and the effects of these four phenolic acids on R. glutinosa growth were studied with water culture.

为了探究酚酸物质与地黄连作障碍之间的关系，检测了重茬地黄土壤中阿魏酸、香草酸、香草醛和对羟基苯甲酸等4种酚酸物质的积累量，并通过水培条件下添加酚酸，研究了4种酚酸对地黄生长的影响。

采用毛细管电泳-电化学检测法同时分离测定了中药杠板归中的阿魏酸、香草酸、槲皮素、咖啡酸、原儿茶酸等主要生物活性成分的含量。

Objective:To explore the relationship of negative schizophrenic cognitive function improvement with HVA and 5-HIAA, Method:Thirteen negative schizophrenic patients were treated with clozapine for 8 weeks,Memory,attention,executive function were assessed separately with Waise memory scale,cancellation test and Wisconsin card sorting test before and after treatment,and cerebrospinal fluid HVA and 5-HIAA levels were determined with HPLC-ECD, Results:Part of short memory was improving with decreasing of HVA or increasing of 5-HIAA,while significant correlation were not found between improvement of memory quotient,attention,executive function and change of HVA,5-HIAA, Conclusion:The great part of negative schizophrenic cognitive function improvement has marked correlation with change of DA and 5-HT

目的：探讨阴性精神分裂症认知功能的改善与HVA和5-HIAA变化的关系。方法：对13例阴性精神分裂症在氯氮平治疗前和治疗8周后分别采用韦氏成人记忆量表，数字划消测验和威斯康星卡片分类测验(Wisconsin card sorting test，WCST)评估其记忆、注意及执行功能，采用高效液相色谱-电化学检测测定其治疗前和治疗后脑脊液中DA代谢产物高香草酸和5-HT代谢产物五羟吲哚乙酸(5-HIAA)的浓度。结果：部分短时记忆随HVA降低或5-HIAA的增高而改善。而总的记忆商数，注意及执行功能的改善与HVA和5-HIAA的变化无明显相关。结论：大部分阴性精神分裂症认知功能的改善与DA和5-HT浓度变化无明显相关。

Prolong bake time can improve weatherproofing of oxalate coating.

It is considered that these materials are derived from different sources: calcite comes from cigarette paper, whewellite is crystallized during the growth of tobacco leaf itself, and gypsum is formed in the combustion process of cigarette.

这些矿物具有不同的来源：方解石来自卷烟纸，一水草酸钙石是烟叶生长期间自身合成的矿物，石膏是香烟燃烧过程中新形成的矿物。

The mineral constituents of the precipitates are confirmed to be lepidocrocite, calcite, whewellite and hydromuscovite under the polarized microscope and through infrared spectrum analysis.

在偏光镜下和通过红外光谱分析确认沉淀物为纤铁矿、方解石、水草酸钙石和水白云母等。

The microscopic examinations of sediment demonstrated RBC urine in 46 cases (50%),RBC morphology was homogenerous type under the light microscope; WBC urine in 33 cases (35.9%), of which cultures for microorganism in 12 cases were all negative; crystal urine in 14 cases (15.2%), of which noncrystal type crystal was identified in 12 cases, while calcium oxalate crystal in 2 cases.

沉渣镜检：红细胞尿40例，占50%，普通光镜下观察红细胞形态为均一型。白细胞尿33例，占35.9%，干化学、沉渣镜检阳性符合23例，其中12例尿培养未检出致病菌。结晶尿14例，占15.2%，其中12例非晶型结晶有4例按混浊尿鉴别程序确定为非晶型尿酸盐结晶；另2例为草酸钙结晶。
