抑郁症( depression )是情感性精神障碍( mood disorders )的主要类型 , 是一种以显著而持久的心境低落为主要特征的综合征。抑郁症是危害人类身 心健康的常见病、 多发病, 是一个全球性的主要精神问题。 据统计在一般人 口中大约有 25%女性在其一生中经历过抑郁症,男性中约有 10%左右经历过 抑郁症(张春兴著: 《现代心理学》 )。 世界卫生组织提供的资料: 抑郁症 在全世界的发病率约为 11%, 目前全球约有 3.4亿精神抑郁患者, 而且这个 数字仍成上升趋势, 调查发现在今后 20年, 抑郁症将会上升为全球第二大 常见疾病。
目前国内外市场上抗抑郁症药物中基本以百优解、 赛洛特、 左洛复等 5 羟色胺再摄取抑制剂 (SSRIs ) 为主, 其作用机理是通过调节人体单胺类神 经递质 5羟色胺等成分含量緩解抑郁症状。这类药物都有不同程度的副作用, 研究表明 "这些药品中含有的复安栓对平衡人体机能有作用, 但更多时候, 它们还是无法让患者平静下来。 ,, 近年来, 百优解等抑郁症药物是否有害已 成为严重的社会问题, 其中赛洛特更是早在 1996年就被发现存在有安全隐 患, 自 2001年开始已陆续从市场上召回。 2004年 6月, 美国紐约州总检察 长指控英国葛兰素史克公司为了获取利润, 欺骗性隐瞒了服用赛洛特与 "增 加青少年自杀倾向及行为的风险" 之间有联系的研究报告。 在这种背景下, 如何研发生产新一代副作用小又能有明显抗郁作用的药物已成为全球医药 界所关注的问题。 发明内容

Nova-pakC18 , 5 μ m (中国科学院大连化学物理研究所国家色语研究分析中 心填装) ; 流动相为 50mM柠檬酸-乙酸钠緩冲液 PH3.5 (内含 1.0mM B-8 离子对试剂, 1.8mM二正丁胺, 0.3mMEDTA二钠, 4 %甲醇) , 流速 l.OmL/min,玻璃碳工作电极,检测池电压为 +0.75V; 3 , 4 -二羟苄胺 DHBA 为内标物, 样品中各主要组分用内标法进行定量。 2.4 统计学处理 实验数据以均数土标准差( ^ ± s )表示, 采用 SPSS13.0统计软件, 运 用单因素方差分析 ( one-way ANOVA )进行各组间比较, 显著性水平以 0.05和 0.01为标准。
3 实验结果
结果表明, 连续给药 21天后, 与空白组比较, 模型组大鼠脑内单胺类 神经递质去曱肾上腺素、 5-羟色胺含量降低(p<0.05 ), 与模型组相比较, 芍甘胶嚢中、高剂量组和阳性药盐酸氟西汀组大鼠脑内单胺类神经递质去 曱肾上腺素、 5-羟色胺含量升高 (PO.05 ) , 结果参见表 7和表 8。 表 7 芍甘胶嚢对脑内去甲肾上腺素的影响 ( 士 s )
