| 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。

| Abstract: | 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. |
