摘　　要：目的:研究宁夏鲜枸杞原汁对小鼠的抗运动性疲劳的作用。方法:将宁夏鲜枸杞原汁分为8.3、16.6、25ml/(kg·d)三个剂量组给小鼠灌胃,对照组给等剂量生理盐水,共21d。末次喂养后,负重游泳小鼠游泳至死并记录小鼠入水游泳至死亡时间,其他小鼠按不同测试指标运动方案使其疲劳,测定肝糖原、血乳酸(LAC)、血尿素氮(BUN)的含量。结果:25ml/(kg·d)剂量的灌服宁夏鲜枸杞原汁能明显延长小鼠负重游泳时间,提高小鼠运动后体内肝糖原的含量,降低血尿素氮(BUN)和血乳酸(LAC)的含量;16.6ml/(kg·d)剂量的灌服宁夏鲜枸杞原汁只延长小鼠负重游泳时间、降低血乳酸(LAC)的含量,而对体内肝糖原含量、血尿素氮(BUN)含量的影响差异无显著性意义;8.3ml/(kg·d)剂量的灌服宁夏鲜枸杞原汁对所测疲劳指标的影响差异均无显著性意义。结论:对小鼠进行适宜剂量的灌服鲜枸杞原汁具有良好的抗运动性疲劳作用。Objective：To study the anti-fatigue effect of raw juice from Lycium Chinense Mill. Method：There were groups of mice given raw juice from Lycium chinense Mill at doses of 8.3,16.6,25ml/（kg.d）,and a control group given saline. All mice were fed through gastric tube for 21 days. After the last fed, mice were forced to swim to induce fatigue. Exhaustion time of exercises, liver glycogen, blood lactic acid and blood urea nitrogen （BUN） were measured. Result：The dose of 25ml/（kg.d） input provided obvious effect on prolonging the swimming time and increasing the liver glycogen of mice. It could also reduce BUN and LAC. The dose of 16.6ml/（kg.d） input could only prolong the swimming time and reduce LAC and had no statistics meaning to BUN. The dose of 8.3ml/（kg. d） input had no meaning to all the fatigue factors. Conclusion：The proper input dose of raw juice from Lycium chinense Mill has considerable anti-fatigue effect on mice.
