摘要
目的:观察低强度激光对衰老模型小鼠的抗氧化系统的影响。方法:以D-半乳糖致小鼠亚急性衰老,低强度激光照射处理后,取小鼠血液,测量其T-SOD活性、GSH、MDA含量,观察其变化。结果:与模型组比较,大剂量组(B组)的T-SOD活性显著提高(P<0.01),GSH含量升高(P<0.05),MDA含量则显著降低(P<0.01),小剂量组(C组)各项指标与模型组比较无明显差异(P>0.05)。结论:一定剂量的低强度激光可影响D-半乳糖所致衰老模型小鼠抗氧化系统,增强抗氧化能力。
Objective： To observe the effect on anti-oxidative system of the aging mice. Methods： Mice were aged caused by D-galactose. After these mice were irradiated by low intensity laser. The activity of SOD, the contents of GSH and MDA in blood of the mice were observed. Results： Low intensity laser irradiation can obviously promote the activity of SOD and the contents of GSH in blood, and also lower contents of MDA of aged model mice in B group. Conclusions： Some doses of low intensity laser irradiation can influence the antioxodative system and improve antioxidative ability of aging mice caused by D-galactose.
