摘要: 目的:通过灌服南极磷虾脱脂蛋白肽研究其对小鼠抗疲劳、耐缺氧能力的影响。方法:对照组小鼠灌胃蒸馏水,低剂量组、中剂量组和高剂量组分别以南极磷虾脱脂蛋白肽灌胃,灌胃剂量分别为0.2、1.0、5.0g/(kg ·d),连续28d。分别测定小鼠负重游泳时间和血乳酸(LA)、血尿素氮(BUN)、乳酸脱氢酶(LDH)、肝糖原含量;常压耐缺氧时间及耗氧量、亚硝酸钠中毒存活时间。结果:高剂量组小鼠负重游泳时间及血清中LDH含量、LA清除率及肝糖原含量明显高于空白组,BUN含量明显低于空白组。高剂量组常压耐缺氧存活时间及亚硝酸钠中毒存活时间明显高于空白组。结论:南极磷虾脱脂蛋白肽能明显提高小鼠抗疲劳、耐缺氧的能力,具有非常明显的保健作用。

Abstract: Objective: To explore the anti-fatigue and anti-hypoxia effect of degreased peptides from Antarctic krill in mice. Methods: The mice were randomly divided into four groups including the control group administered with water and three experimental groups administered with degreased peptides from Antarctic krill at doses of 0.2, 1.0, 5.0 g/(kg ·d) for 28 consecutive days, respectively. The swimming time and the contents of lactic acid (LA), blood urea nitrogen (BUN) and lactate dehydrogenase (LDH) in serum, liver glycogen, survival time and oxygen consumption in hypoxia tolerance test, survival time after sodium nitrite poisoning were determined. Results: The degreased peptides from Antarctic krill at high dose could improve the swimming time, serum LDH activity, lactate clearance rate and the content of liver glycogen and decrease BUN in serum. Meanwhile, these degreased peptides at high dose could also increase the survival time in both hypoxia tolerance test and sodium nitrite poisoning experiment. Conclusion: The degreased peptides from Antarctic krill can eliminate fatigue and increase anti-hypoxia capacity in vivo. These investigations will have a significant impact on human health care.

Key words: Antarctic krill, degreased peptides, anti-fatigue, anti-hypoxia, mice
