磁场对家兔血清谷胱甘肽过氧化物酶及血液过氧化氢酶活性的影响

The effect of magnetic field on activities of glutathione peroxidase in serum and catalase in blood of rabbits

目的 :探讨磁场对家兔谷胱甘肽过氧化物酶 ( GSH- Px)和过氧化氢酶 ( CAT)活性的影响。方法 :将 2 0只家兔随机分为实验组与对照组。实验组每天进行一次磁处理 ,每次 30 min。在家兔腹背贴磁片 ,每一磁片的磁感应强度 0 .2 T。6周后测定两组家兔血清中 GSH- Px和血液中 CAT的活性。结果 :实验组 GSH- Px活性为 ( 1 438.5 0± 1 5 7.89)活力单位 /ml,CAT活性为 ( 68.2 9± 1 3.91 )活力单位 /L。对照组 GSH- Px活性为 ( 1 1 87.73± 2 72 .5 5 )活力单位 /ml,CAT活性为 ( 5 5 .69± 7.5 7)活力单位 /L。实验组 GSH- Px与 CAT活性明显升高 ( P<0 .0 5 )。结论 :磁场能够增强 GSH- Px和 CAT的活性 ,提高机体处理自由基的能力 ,增加机体的抵抗能力 ,具有一定的抗衰老功能。

Objective: In order to study effect of magnetic field on activities of catalase (CAT) and glutathione peroxidase (GSH Px) of rabbits. Methods: Twenty rabbits were divided into tested and control groups. The rabbits of tested group were treated by magnetic field every day,dealling time was 30 min. Magnetic pieces were put on back and abdomen skin of animals. After dealling for 6 weeks,activities of GSH Px in serum and CAT in blood of total rabbits were determined. Results: Compared with control group,GSH Px and CAT activites in experimental group were obviously increased ( P <0.05).Conclusion: Magnetic field may stimulate activities of GSH Px and CAT,enhance the ability of organism to remove free radicals,increase resistance of organism,therefore, magnetic field may function against aging.
