| 摘 要： | 目的探讨外源性牛磺酸对力竭运动后大鼠白肌线粒体自由基代谢的影响,从亚细胞水平研究牛磺酸抗运动性疲劳的机制。方法以大鼠力竭性运动为模型,观察了牛磺酸对力竭运动时大鼠白肌线粒体脂质过氧化、抗氧化系统及总Ca2+浓度的影响。结果牛磺酸可降低大鼠力竭运动后白肌线粒体脂质过氧化水平,提高大鼠力竭运动后白肌线粒体超氧化物歧化酶(SOD)的活性,保持大鼠力竭运动后白肌线粒体还原性谷胱甘肽含量及总Ca2+浓度。结论牛磺酸可减少力竭运动后因脂质过氧化而产生的自由基,降低自由基对白肌线粒体的攻击,维持线粒体膜的功能。 |

| Abstract: | Aim To probe into the effects of taurine on fast muscular mitochondria in rats after exhaustive exercise.Methods Taking incremental exercise to exhaustion, the authors measured MDA content SOD activity GSH content and Total calcium concentration of the fast muscular mitochondria in rats at rest, immediately after exhaustive having supplied with 1% taurine in drinking water during four weeks or not.Results Taurine supplement decreased the lipid peroxidation level and increased SOD activities, GSH content and total calcium concentration significantly in the fast muscular mitochondria of rats after exhaustive exercise.Conclusion Taurine could decrease free radicals, and thus protect the damage of fast muscular mitochondria from the lipid peroxidation after exhaustive exercise and retain the function of the fast muscular mitochondria. |
| Keywords: | taurine rat mitochondria muscle free radicals exercise |
