黑加仑提取物抗疲劳作用的动物实验研究

THE ANTI-FATIGUE EFFECT OF BLACK CURRANT EXTRACTS IN MICE

目的研究黑加仑提取物抗疲劳作用。方法将SPF级昆明种小鼠按体重随机分成黑加仑提取物高、中、低剂量组、黑加仑原汁组和溶剂对照组。每日灌胃1次,连续30d后,分别测定小鼠负重游泳时间、肝糖原含量、血清尿素氮含量。结果黑加仑提取物各剂量组能延长小鼠负重游泳时间、增加肝糖原含量、减少血清尿素氮含量。与黑加仑原汁组比较,黑加仑提取物高、中、低剂量组负重游泳时间均延长,肝糖原含量均升高,高、中剂量组血清尿素氮含量均降低。结论黑加仑提取物具有一定的抗疲劳作用,且优于黑加仑原汁组。

Objective To study the anti-fatigue function of black currant extracts in mice. Method Kunming mice （SPF） were randomly divided into black currant extracts high, middle, low dose group, black currant natural juice dose group and control group according to their body weights. Mice were administered ig daily for 30 d. The loaded-swimming time ,hepatic glycogen ,blood urea nitrogen were measured. Results Black currant extracts high, middle, low dose groups could increase the time of loading swimming, and the hepatic glycogen content, and decrease blood urea nitrogen in mice. All indices above were more than those in black currant natural juice except the blood urea nitrogen content was lower. Conclusion Black currant extracts could alleviate physical fatigue in mice, and be better than black currant natural juice.
