投资者“垂涎”中药市场

医疗咨询机构IMS称，过去十年，传统中药在中国医药市场的份额已从7％上升到11％,如今年销售额逾25亿美元。中国食品药品监督管理局表示，传统中药占总体药品市场的36％。

Simultaneous determination of berberine, matrine and oxymatrine in traditional Chinese medicines by using nonaqueous capillary electrophoresis

A rapid method for the simultaneous determination of berberine (BBR), matrine (MT) and oxymatrine (OMT) by nonaqueous capillary electrophoresis (NACE) was developed. Optimum separation of the analytes was obtained on a 50cm×50μm i.d. fused-silica capillary using a non-aqueous buffer system of 70mM ammonium acetate, 7.0% acetic acid and 10% acetonitrile at 25kV and 20℃. The relative standard deviations (R.S.D.) of the migration times and peak areas of the three active components were 0.06%-0.20% and 0.12%-3.41% for berberine, 0.11%-0.60% and 0.74%-1.63% for matrine, 0.15% and 0.45% for oxymatrine, respectively. Detection limits of berberine, matrine and oxymtrine were 0.18μg/mL, 4.08μg/mL and 4.16μg/mL, respectively. In the tested concentration range, good linear relationships (0.9992 for berberine, 0.9988 for matrine and 0.9988 for oxymatrine) were observed. The linear calibration ranges were 0.45-360.0μg/mL for berberine, 8.16-408.0μg/mL for matrine and 20.8-416.0μg/mL for oxymatrine. This method has been successfully applied to the phytochemical analysis of alkaloids extracts from two commonly used traditional Chinese herbal drugs: Sophora flavescens Ait. (Kushen) and Cortex phellodendri chinensis (Huangbai) and their medicinal preparations.     

中药复方对大鼠脑血流量的影响

用由人参、当归、三七、水姓、红花、黄芪、川可、丹参、淫羊藿、枸杞、熟地、枣皮、益智仁、首乌组成的中药给正常SD大鼠灌胃3d后，观察脑血流量的变化。结果示：不同剂量的中药均增加大鼠脑血流量，与对照组比较差异显著（P＜0．05）。表明本实验所用中药具有增加SD大鼠脑血流量作用。     

论“学习迁移”规律在药理学教学中的应用

“学习迁移”是教育心理学研究的一个重要课题。学习迁移规律在药理学教学中的应用有助于提高教学质量和开拓医学生的智能。
