摘要
目的:研究玉米肽缓解小鼠体力疲劳的作用。方法:分别将小鼠按体重随机分成4组,即空白对照组和玉米肽低、中、高3个剂量组。灌胃不同剂量玉米肽样品30 d后,观察各组小鼠负重游泳(WLS)时间、肝糖原含量以及游泳后血清尿素氮、血乳酸指标的变化。结果:玉米肽3个剂量组与空白对照组相比,小鼠WLS时间存在显著差异(P<0.05),中剂量组小鼠肝糖原储备量较空白对照组有显著提高(P<0.05),该组小鼠运动后血清尿素氮水平较空白对照组显著降低(P<0.05)。各剂量组处理后,小鼠血乳酸曲线下面积均有降低,然而未表现出显著差异(P>0.05)。结论:玉米肽具有缓解小鼠体力疲劳的作用。
Objective:To explore the alleviating physical fatigue effect of corn peptide in mice.Methods:The mice were divided into the control group(casein)and the low,medium and high dose group by their weight.Mice in three dose groups were orally given corn peptide samples for 30 d with various dose.The time of weight loaded swimming(WLS),hepatic glycogen level,serum urea and blood lactic acid levels after swimming were observed sequentially.Results:Compared with control group,the result showed that the corn peptide could significantly improve the load swimming time in three dose groups(P<0.05).The hepatic glycogen contents in medium dose group had a significant increase(P<0.05)as well as decrease remarkably in serum urea nitrogen contents after swimming(P<0.05),however the blood lactic acid level and AUC in three dose groups proved no statistical significance(P>0.05)after swimming.Conclusion:Corn peptide has an effect on alleviating physical fatigue in mice with in a certain dose.
