【摘要】 实验观察蚕蛹蛋白多肽对小鼠抗疲劳作用的影响。实验将蚕蛹蛋白多肽分为高、中、低剂量组,分别为2.4、1.2、0.6g/kg·d喂饲小鼠28d,观察小鼠爬杆时间、负重游泳时间,测定血清尿素氮、肝糖原和肌糖原含量,测定游泳前、游泳后0、15、60min血清乳酸含量的变化。实验结果表明:蚕蛹蛋白多肽能显著增加小鼠爬杆时间和负重游泳时间,增加小鼠运动过程中肝糖原和肌糖原含量,减少血清尿素氮的含量,并能显著降低游泳后血清乳酸的增加量。说明蚕蛹蛋白多肽具有明显的抗疲劳作用。更多还原

【Abstract】 Mice subjected to experiments were randomly divided into four groups of 72 each (control group,low-,middle-and high-dose groups),which were fed silkworm pupa protein polypeptide at doses of 0,0.6,1.2 and 2.4g/kg·d for 28 days,respectively. Pole-climbing time and weigh-loaded swimming time of mice were recorded. Along with this,serum urea nitrogen,liver glycogen,muscle glycogen and serum lactate of mice before swimming and after swimming at time points of 0,15 and 60 min were determined. Results indicate that silkworm polypeptides could significantly prolong pole-climbing time and maximum weight-loaded swimming time,promote synthesis of liver glycogen and muscle glycogen,decrease serum urea nitrogen and lactate. Therefore,silkworm pupa protein polypeptides have significant anti-fatigue function.更多还原
