中文摘要:

采用低功率激光对一次性离心力竭运动大鼠跟腱进行照射，采用生物化学测定和组织学技术观察的方法，分析低功率激光照射对跟腱蛋白多糖含量影响，探讨低功率激光照射对力竭运动后早期跟腱微损伤修复中的作用。结果显示：一次性离心力竭运动大鼠跟腱中蛋白多糖含量显著高于空白对照组；激光照射组蛋白多糖含量的变化与自然愈合组一样，是随时间增加而逐渐升高，但增加幅度要大于自然愈合组。表明低功率激光照射能促进大鼠跟腱蛋白多糖的合成，加快跟腱细胞外基质成分的恢复，有利于受损跟腱的修复。

英文摘要:

Low-power laser irradiation was applied to the Achilles tendon of the rats which experienced one-time exhaustive eccentric exercise, as well as the method of biochemical measurement and histological technology observation. The effect of low-power laser irradiation on the proteoglycan content of Achilles tendon was analyzed so as to explore the function of low-power laser irradiation in the early-stage micro-damage repair of Achilles tendon after exhaustive exercise. The result shows that the proteoglycan content of the rat's Achilles tendon after one-time exhaustive eccentric exercise was significantly higher than that of the control group. The changes of the proteoglycan content of the laser irradiation group was the same as that of the natural healing group. The content of both increased gradually as time passed. However, the rate of increase was greater than that of the natural healing group. This indicates that low-power laser irradiation can promote the proteoglycan synthesis of the rat's Achilles tendon and accelerate the recovery of Achilles tendon extracellular matrix, which is conducive to the repair of damaged Achilles tendon.
