【摘要】 用中草药杜仲皮、叶煎剂及叶冲剂给小白鼠灌胃或自饮给药,并与对照组比较,结果:皮煎剂能显著延长鼠的游泳时间,平均为47分钟(n=12);皮及叶煎剂能明显延长鼠-3℃低温环境中的生存时间:分别为67分钟(n=14)、74分钟(n=20);并能延长缺氧条件下的成活时间:各为14分钟(n=7)、7分钟(n=7);显著减少鼠自发活动次数,由此表明,杜仲具有增强动物对外界刺激的耐受能力;并具有中枢性镇静作用。更多还原

【Abstract】 The tonic effect of different parts of eucommia ulmoides oliv has beentested on mice. The decoction of cortex and leaves extended their swimming time to about 47 (n=12) and 24 (n=15) times respectively- prolonged the survival time of mice in cold and anoxia conditions for about 67 min (n=14) . 74 min (n=20) and 14 min (n=7), 7 min (n= 7 ) respectively. In addition, it can also decrease the spontaneous activity times of mice. From the experimental results mentioned above it may be suggested that eucommia ulmoides oliv has central sedative effect as well as tonic effect.更多还原
