酶法提取木枣多糖对游泳小鼠血清酶的影响

目的:从木枣多糖中寻找和筛选抗疲劳组分,探讨其对运动机体的作用机制。方法:用不同方法从木枣中提取得到两种粗多糖,以雄性小鼠为实验对象,采用一次性力竭试验,筛选效果最强组分;又建立递增强度游泳训练模型,对小鼠灌服木枣多糖溶液,四周后测定小鼠血清肌酸激酶(CK)、谷草转氨酶(GOT)、谷丙转氨酶(GPT)、乳酸脱氢酶(LDH)、血清抗氧化酶活性等指标,结果显示:服用一定剂量酶提木枣多糖能使上述血清酶呈现不同程度的变化。结论:说明木枣多糖可能具有提高运动能力的作用。

Influence of Enzyme-based Extracting Jujube Polysaccharide to Serum Kinase on Swimming Mice

Objective: To find alleviate sport fatigue composition form Jujube polysaccharide and to investigate it’s relative principle in sport body. Methods: With different withdraw method, get two kinds of sugar form Jujube polysaccharide, take male rat for test object, building up exhaust training model, finding the better composition; and building up a swimming model, infusing this Jujube polysaccharide to the rat, measured the activity of creatine kinase, alanine aminotransferase, aspartate aminotransferase, lactate dehydrogenase, superoxide dismutase, glutathione peroxide in serum after four weeks. Result: En- zyme-based extracting Jujube polysaccharide can raise the activity of superoxide dismutase, glutathione peroxide in serum, reduced the activity of creatine kinase, alanine aminotransferase, aspartate aminotransferase and Lactate dehydrogenase in serum. Conclusion: It is proved that enzyme-based extracting Jujube polysaccharide can alleviate sport fatigue.
