| 摘 要： | 分析中药沙苑子对运动性疲劳模型大鼠血清支链氨基酸(branched-chain amino acid,BCAA)及芳香族氨基酸(aromatic amino acid,AAA)的影响,为沙苑子作为运动保健品的开发利用提供实验依据.选用SD(Sprague Dawley,SD)雄性大鼠24只,体重190~230 g,随机分为安静对照组、一般训练组、强化训练组、强化加药组(各6只),进行7周递增负荷跑台运动建立运动性疲劳大鼠模型,于第8周始运动即刻后取材,运用氨基酸自动分析仪测定大鼠血清游离氨基酸含量.结果表明,长时间耐力跑台运动应激使大鼠血清BCAA含量有所下降,AAA尤其是游离色氨酸(free-tryptophan,f-Trp)含量上升,沙苑子可抑制BCAA下降、AAA上升趋势;长时间耐力跑台运动使实验大鼠血清f-Trp/BCAA、AAA/BCAA显著增加,运动过程中血中蛋白质代谢增强,BCAA大量分解供能,AAA相对增多,从而使f-Trp/BCAA、AAA/BCAA增高.沙苑子可以抑制f-Trp/BCAA、AAA/BCAA上升,且对强化训练引起的f-Trp/BCAA、AAA/BCAA升高有显著的降低作用.沙...

| Abstract: | Based on the effects of the semen astragali complanati on BCAA and AAA levels of blood in exercise-induced fatigue rats.24 male SD rats with weight 190~230 g were randomly divided into 4 groups as Sedentary Group,Model Group,Drill Group and Treatment Group.and given 7 weeks of endurance treadmill training and the free amino acids in serum were tested by amino acid automatic analytical instrument.The results showed that the content of serum branched chain amino acid(BCAA) and aromatic amino acid(AAA) especia... |
