目的研究小米多肽对小鼠的抗疲劳作用。方法小米多肽分为0.2、0.4、0.8 g/(kg.d)高、中、低剂量组,喂饲小鼠30 d,观察小鼠负重游泳时间,测定肝糖原和血清尿素氮含量。结果 0.4、0.8 g/(kg.d)小米多肽剂量组小鼠负重游泳时间与阴性对照组比较分别增加4.45和10.51 min(P<0.01),小鼠运动过程中肝糖原含量分别为(9.83±0.10),(10.15±0.21)mg/g,与阴性对照组比较差异有统计学意义(P<0.01),血清尿素氮的含量明显减少(P<0.01)。结论小米多肽对小鼠有明显的抗疲劳作用。
Objective To study the anti-fatigue effect of millet polypeptide on mice. Methods The millet peptides were divided into high, medium and low dose groups of 0.2, 0.4 and 0.8 g / (kg · d) for 30 d. The weight-bearing swimming time of mice was observed and the contents of hepatic glycogen and serum urea nitrogen were measured. Results Compared with the negative control group, the weight-bearing swimming time of the 0.4,0.8 g / (kg · d) millet polypeptide dose group increased by 4.45 and 10.51 min (P <0.01), and the content of hepatic glycogen in the mice during exercise was (9.83 ± 0.10) and (10.15 ± 0.21) mg / g, respectively, which were significantly different from those of the negative control group (P <0.01). The content of serum urea nitrogen was significantly decreased (P <0.01). Conclusion Millet peptides have obvious anti-fatigue effect on mice.
