摘　　要：背景:白花败酱草为败酱科植物,味辛、苦性寒,已证实白花败酱草提取物具有中枢抑制作用。目的:观察中药白花败酱草提取物对小鼠耐缺氧的作用,并了解其作用是否有剂量依赖性。设计:随机对照动物实验。单位:赣南医学院药理教研室和病理教研室。材料:实验于2005-03/04在赣南医学院科研中心实验室完成。取健康成年昆明种小鼠100只,用于3个缺氧实验。方法:①常压耐缺氧实验:取小鼠40只随机分为4组:生理盐水组腹腔注射生理盐水2μL/g,普萘洛尔组腹腔注射10g/L普萘洛尔溶液0.02mg/g,白花败酱草0.02,0.04mg/g组腹腔注射白花败酱草提取物0.02,0.04mg/g。25min后,将小鼠放入250mL的磨口广口瓶内,密封,观察小鼠的存活时间。②快速断头实验:取小鼠30只随机分为3组:生理盐水组腹腔注射生理盐水2μL/g,白花败酱草0.02,0.04mg/g组分别于腹腔注射白花败酱草提取物0.02,0.04mg/g,25min后,快速断头,记录小鼠断头后至最后一次喘息所需的时间。③结扎双侧颈总动脉实验:取小鼠30只随机分为3组:生理盐水组灌胃生理盐水2μL/g,白花败酱草组0.01,0.015mg/g灌胃,1次/d,共7d,7d后结扎双侧颈总动脉观察呼吸停止的时间。主要观察指标:①小鼠常压耐缺氧的存活时间。②小鼠脑缺血断头后至最后一次喘息的时间。③小鼠结扎双侧颈总动脉至呼吸停止的时间。结果:100只小鼠全部进入结果分析。①常压耐缺氧条件下鼠的存活时间:白花败酱草0.02,0.04mg/g组显著长于生理盐水组[(57.8±4.6),(76.2±4.9),(42.5±3.6)min,P<0.05,0.01],与普萘洛尔组比较无差异(P>0.05),剂量越大,存活时间越长。②断头小鼠的喘息时间:白花败酱草0.02,0.04mg/g组显著长于生理盐水组[(22.1±1.6),(25.3±2.2),(18.6±0.8)s,P<0.05,0.01],剂量越大,存活时间越长。③结扎双侧颈总动脉小鼠呼吸停止的时间:白花败酱草提取物0.01,0.015mg/g组显著长于生理盐水组[BACKGROUND： As a plant in valerianaceae, patrina villosa juss, which characterizes by acrid and bitter in taste and cold in nature, has been proved that its extract has effect on central inhibition. OBJECTIVE： To observe the effect of patrina villosa juss extract on hypoxia tolerance of mice and acknowledge whether it has dosage-dependence or not. DESIGN： Randomized controlled animal study. SETTING： Pharmacological Department and Pathological Department of Gannan Medical College. MATERIALS： The experiment was completed at the Laboratory of Scientific Research Center of Gannan Medical College from March to April 2005. A total of 100 healthy adult Kunming mice were selected in three hypoxia experiments. METHODS： ① Hypoxia tolerance experiment under normal pressure： Forty mice were randomly divided into 4 groups. Mice were injected intravenously with 2 μL/g saline in saline group, with 0.02 mg/g propranolol solution （10 g/L） in propranolol group, with 0.02 mg/g patrina villosa juss extract in 0.02 mg/g patrina villosa juss group, and 0.04 mg/g patrina villosa juss extract in 0.04 mg/g patrina villosa juss group, respectively. Twenty-five minutes later, mice were put into wide mouthed bottle with the volume of 250 mL and the bottle was enclosed to observe the survival time. ② Rapid decapitation experiment： Thirty mice were randomly divided into 3 groups. Mice were injected intravenously with 2μL/g saline in saline group, with 0.02 mg/g patrina villosa juss extract in 0.02 mg/g patrina villosa juss group, and 0.04 mg/g patrina villosa juss extract in 0.04 mg/g patrina villosa juss group, respectively. Twenty-five minutes later, heads of mice were cut rapidly to record the time from decapitation to the last gasp. ③ Experiment for ligating bilateral common carotid artery： Thirty mice were randomly divided into 3 groups. Mice were perfused with 2 μL/g saline in saline group, with 0.01 mg/g patrina villosa juss extract in 0.01 mg/g patrina villosa juss group, and 0.015 mg/g patrin
