摘要 目的:对柴胡等7种中草药的超临界CO2萃取物进行抗惊厥作用的比较,并初步探讨其作用机制。方法:将昆明种小鼠1 060只随机分为11组,柴胡CO2萃取物组(柴Ⅰ)、柴胡CO2乙醇提取物组(柴Ⅱ)、石菖蒲CO2萃取物组(石Ⅰ)、石菖蒲CO2乙醇提取物组(石Ⅱ)、天南星CO2乙醇提取物组(天Ⅱ)、钩藤CO2乙醇提取物组(钩Ⅱ)、半夏CO2乙醇提取物组(半Ⅱ)、瑞香狼毒CO2萃取物组(狼Ⅰ)和柏子仁CO2萃取物组(柏Ⅰ)、托吡酯组、生理盐水组,每组分为4~6个剂量组,每个剂量组20只,ig给药,观察各剂量组对最大电休克(maximal electroshock seizure,MES)模型的对抗作用;以上述各药抗MES惊厥的ED50为给药剂量,观察ig各药对小鼠戊四唑惊厥模型(metrazol seizure test,MET)的对抗作用;由小鼠抗MES惊厥的ED95折算得到大鼠ig剂量,建立大鼠皮层定位注射青霉素点燃模型,比较各药对惊厥行为和脑电图的影响。结果:①9种受试中药提取物中天Ⅱ、钩Ⅱ、石Ⅰ、半Ⅱ、狼Ⅰ、柴Ⅰ、石Ⅱ对MES模型均有对抗作用,且量效均呈正相关性。②7种受试中药提取物均可延长MET惊厥潜伏期,数值由大到小排列依次为天Ⅱ、钩Ⅱ、石Ⅰ、半Ⅱ、狼Ⅰ、柴Ⅰ、石Ⅱ,其中天Ⅱ(11.06±4.32)min的作用效果优于托吡酯(9.57±4.47)min。③CO2萃取物较CO2乙醇萃取物起效快,作用持续时间短。(4)半Ⅱ、柴Ⅰ、天Ⅱ、钩Ⅱ、石Ⅰ、石Ⅱ均可不同程度的延长青霉素诱发的痫性发作潜伏期、减轻发作程度,延长痫性放电的潜伏期,减少痫波发放频率,减小放电最高波幅。结论:天Ⅱ、钩Ⅱ、石Ⅰ、半Ⅱ、狼Ⅰ、柴Ⅰ、石Ⅱ均可对抗小鼠MES和MET惊厥;半Ⅱ、柴Ⅰ、天Ⅱ、钩Ⅱ、石Ⅰ、石Ⅱ可抑制大鼠皮层定位注射青霉素诱发的癫痫发作和痫性放电,其中半Ⅱ是对抗青霉素点燃惊厥发作最有效的药物,且对该模型的对抗作用优于托吡酯。 Objective: To compare the anticonvulsion effect of supercritical-CO2 fluid extractions (SFE-CO2) of Bupleuri Radix , and explore their mechanism. Method: One thousand and sixty mice were randomly divided into Ⅱ groups: RB I group, RB Ⅱ group, RAT Ⅰ group, RAT Ⅱ group, AR 11 group, UN Ⅱ group, PR Ⅱ group, SCL Ⅰ group, PSⅠ group, topamax group and NS group. Every group was divided into 4-6 dose groups.
