半导体激光照射对耐药细菌最低抑菌浓度的影响及分析

The Influence of Diode Laser Irradiation on the Minimal Inhibitory Concentration of Drug Resistant Bacteria

目的:研究弱激光照射对耐药菌耐药性的影响,探讨弱激光体外照射治疗疾病的机理。方法:利用低功率半导体激光照射耐药菌,检测抗生素对其最低抑菌浓度(MIC)的变化。结果:经半导体激光照射后,抗生素对耐甲氧西林金黄色葡萄球的最低抑菌浓度有明显降低。结论:低能量半导体激光照射可使耐药菌耐药性下降,但可否降低至敏感或中敏尚需进一步实验设计与验证。

Objective： This study was conducted to investigate the effect of a diode laser on the drug resistance of some species of bacteria. Some experimental data may be provided in order to suggest the mechanism of laser irradiation in cure disease. Methods： Drug resistant bacteria were irradiated with a diode laser. Effect on that was obsérved by means of testing the MIC （minimal inhibitory concentration）. Result： There were significant differences between different experimental groups. Conclusion： The drug resistance level of bacteria dropped after irradiation with low energy diode laser. But there need more experiments to confirm it.
