竹叶提取物的抗缺氧作用

目的观察竹叶提取物的抗缺氧作用,为竹叶提取物的临床新用途提供实验依据.方法采用小鼠常压耐缺氧实验、亚硝酸钠中毒小鼠存活时间、氰化钾中毒小鼠存活时间、利多卡因中毒小鼠存活时间、夹闭气管小鼠心电消失时间的影响、断头小鼠张口动作持续时间模型观察竹叶提取物的抗缺氧作用.结果竹叶提取物(22.5 mg/kg,45.0 mg/kg,90.0 mg/kg)可明显延长常压缺氧条件下的小鼠存活时间,延长亚硝酸钠、氰化钾、利多卡因中毒后的小鼠存活时间,延长夹闭气管小鼠心电消失时间,明显延长断头小鼠的喘气时间.结论竹叶提取物能提高整体动物的抗缺氧能力.

Experiment Study of Folium Bambusae Extraot Against Hypoxia

Objective This study evaluates the Anti- hypoxic effect of Fo li um Bambusae extract (FBE). Methods The survival time of mice under the conditi on of closed normobaric hypoxia, and those subjected to KCN, NaNO2 and lidoc aine poisoning, and the time of electrocardiograph disappearance after occlusio n of trachea and the duration of continuous gasping in mice after decapitation were used to evaluate the Anti- hypoxic effect of FBE. Results FBE ( 22.5 m g/kg, 45.0 mg/kg, 90.0 mg/kg) prolonged the survival time of mice under the c ondition of closed normobaric hypoxia, prolonged the survival time in mice subj ected to KCN, NaNO2 and lidocaine poisoning and prolonged the time of electro cardiograph disappearance and the duration of gasping in decapitated mice. Conc lusion FBE can increase the anti- hypoxic effect of animals.
