【摘要】 目的:观察加味酸枣仁汤对肝郁小鼠的镇静催眠作用。方法:300只小鼠随机分为正常对照组、模型组、加味酸枣仁汤大中小剂量组、安定组6组,每组50只。①小鼠自发活动实验:记录给药30 min 后小鼠2 min内的自发活动次数;②阈下剂量戊巴比妥钠诱导小鼠睡眠实验:采用30 mg/kg戊巴比妥钠诱导小鼠睡眠,记录戊巴比妥钠注射后15 min内小鼠翻正反射消失达1 min以上的鼠数;③阈上剂量戊巴比妥钠诱导小鼠睡眠实验:采用50 mg/kg戊巴比妥钠诱导小鼠睡眠,记录小鼠入睡潜伏期和睡眠时间。结果:加味酸枣仁汤能明显减少肝郁小鼠自主活动次数,增加阈下剂量戊巴比妥钠致肝郁小鼠睡眠只数,缩短阈上剂量戊巴比妥钠致肝郁小鼠入睡潜伏期,延长睡眠时间。结论:加味酸枣仁汤对肝郁小鼠有明显的镇静、催眠作用。

Abstract Objective:To make a preliminary study on the sedative and hypnotic effects of Jiawei Suanzaoren decoction to hepatic Qi disorder model mice.Methods:300 mice were randomly divided into normal control group,model group,Jiawei Suanzaoren decoction treatment groulp 1(large dose),group 2(middle dose),group 3(small dose)and diazepam treatment group(n=50).①30 min after the last administration,10 mice were chosen from each group,then spontaneous activity of mice were observed and recorded times in 2 minutes.②30 min after the last administration,20 mice were chosen from each group to intraperitoneally inject 30 mg/kg pentobarbital sodium,then mice whose body righting reflex disappeared for at least 1 min within 15 min after injection were served as sleeping mice to be recorded.③30 min after the last administration,20 mice were chosen from each group to intraperitoneally inject 50 mg/kg pentobarbital sodium,then sleeping latency and sleeping time were recorded.Results:Jiawei Suanzaoren decoction could markedly reduce the spontaneous motor activity,increase the number of sleeping mice induced by subthreshold dose pentobarbital sodium,shorten sleeping latency and prolong sleeping time induced by superthreshold dose pentobarbital sodium.Conclusion:Jiawei Suanzaoren decoction possesses obvious sedative and hypnotic effects on hepatic Qi disorder model mice.

1 材料与方法
1.1 实验材料
1.1.1 实验动物 昆明种小鼠,雌雄各半,体重(26±2)g,中国辐射防护研究院实验动物室提供,动物合格证号:01-3001。
1.1.2 药物与仪器 加味酸枣仁汤,药物组成:酸枣仁、茯苓、川芎、知母、甘草、柴胡、白芍等,购于太原市并州路万民药店,经山西中医学院中药系牛燕珍老师鉴定;戊巴比妥钠,SERVA产品,上海行知化工厂分装,批号060521;安定片,太原三晋制药厂,批号051207;ZZ-6小鼠自主活动测试仪,成都泰盟科技有限公司研制。
1.2 实验方法
1.2.1 分组与给药 300只小鼠随机分为正常对照组、模型组、安定组、加味酸枣仁汤大剂量组(大剂量组)、加味酸枣仁汤中剂量组(中剂量组)、加味酸枣仁汤小剂量组(小剂量组)6组,每组50只。加味酸枣仁汤由山西中医学院科研实验中心自制。取各中药饮片分为3份,分别加10倍、8倍量水煎2次,每次1 h。分别合并水煎液,浓缩为0.5 g/mL、1.0 g/mL、2.0 g/mL备用。安定片,每片 2.5 mg,以水配制成20 %混悬液,现用现配。
