黄元御论治消渴理论初探

黄元御是清代著名的医家,他从\"土枢四象,一气周流\"理论系统地阐发了消渴病发生的机理,认为消渴为厥阴之病,病机在于肝失疏泄致气机升降逆乱,治疗方面注重恢复肝之疏泄功能,突破了传统从\"阴虚燥热\"论治消渴的理论,为消渴病的理论探索及治疗提供了新的思路

Determination of formaldehyde and phenol in waste water with static headspace-GC-FID

建立了静态顶空取样、气相色谱直接分析水样中甲醛和苯酚的方法。该方法有良好的重现性 ,甲醛、苯酚连续测定 6次的相对标准偏差分别为 1.9%和 4.7%。甲醛、苯酚的检测限分别为 0 .5 0 mg/m L和 0 .3 0 mg/m L。方法简便、快速、基底干扰小 ,适用于工业废水中甲醛和苯酚的同时、快速测定A method for determination of formaldehyde and phenol in waste water with static headspace GC FID has been developed. The detection limits for formaldehyde and phenol were 0.50 mg/mL and 0.30 mg/mL, respectively. The relative standard devirations tere 1.9% and 4.7% for those, respectively. The method has been proved to be simple, fast, matrix interference free, and can be used for the fast determination of formaldehyde and phenol in industrial waste water.福建省自然科学基金重点资助项目 (D0 0 2 -0 0 0 2 );; 教育部骨干教师资助计划 (2 0 0 0年

Micro-extraction Determinationof Alkylphenolic Acids in Chinese Patent Medicine GBE with n-hexane Extract by LiquidChromatography - mass Spectrometry

正己烷萃取,并用HPLC-UV、HPLC-MS对中成药银杏浸膏(GBE)中微量烷基酚酸进行定性、定量分析。正己烷萃取效率高、共萃杂质少。在优化的实验条件下,平均回收率为98.9%(n=5)。银杏烷基酚酸(M=346)的HPLC-UV检测限为0.1μg/g,线性范围为0.5～10μg/g。With n-hexane extraction, the qualitative and quantitative analyses of alkylphenolic acids in Chinese patent medicineGBE (Ginkgo Bilobu Extract) were carried out with liquid chromatography-UV detector and mass spectrometry detector. Then-hexane was proven to be a very efficient extracting reagent, and few interfering materials were coextracted. Under the optimizedexperimental conditions, the recovery was 98.9%(n=5), the detection limit was 0.1μg/g, and the linear range was between 0.5～10μg/g for Ginkgo Biloba alkylphenolic acid of molecular weight of 346.厦门市科委夕阳红基金会资助项目(2000-1043

柴郁温胆汤对大鼠抑郁模型行为学及脑内单胺类神经递质的影响

目的:探讨中药复方柴郁温胆汤抗抑郁作用的机制。方法:以孤养加慢性轻度不可预见性应激方法建立大鼠抑郁症模型,用旷场行为测定及糖水消耗试验进行行为学评分,并用高效液相-电化学方法检测其脑内单胺类神经递质的含量,观察模型大鼠给药前后的变化。结果:抑郁症模型大鼠体质量增长缓慢,水平和垂直活动及糖水消耗量均明显减少(P<0.05,P<0.01);杏仁核NE、DA、5-HT、HVA含量减少(P<0.05);纹状体NE、DA、5-HT含量减少(P<0.05)。柴郁温胆汤能改善模型大鼠行为学变化,升高杏仁核NE、5-HIAA、5-HT、HVA(P<0.05)及DA含量(P<0.01),升高纹状体DA和5-HT含量(P<0.05)。结论:柴郁温胆汤具有抗抑郁作用,对中枢单胺类神经递质的调节作用是其疗效机制之一

Determination of PPA in anti-cold medicines by MECC

建立了康泰克、康得等感冒药剂中PPA含量测定的胶束电动毛细管色谱分析法。方法简单、快速、重现性好,可靠性高。A method of micelle electrokinetic capillary chromatography has been developed to detrmine phenylpropanolamine in anti-cold medicines. The method is simple, fast, repeatable, and reliable

Determination of V-B_(12), V-B_6 and V-C in Vitamin Pills with Micelle Electrophoresis Capillary Chromatography

研究建立了胶束电动毛细管色谱同时测定维生素片剂中 V- B12 、V- B6 和 V- C的方法 .采用样品溶液配制后立即分装储存 ,测定前分取的办法 ,克服了 V- C在分析中极易被氧化损失的问题 .A method of micelle electrophoresis capillary chromatography (MECC) for simultaneously determination of V-B_(12), V-B_6 and V-C in vitamin pills has been established. The prepared sample solution was divided into several portions in individual small bottles and stored in refrigerator. The sample was analyzed right after being taken out and discarded after one analysis. In this way, the oxidization of V-C in the sample could be avoided
