激光照射机体产生的生物效应一直是激光生物学与激光医学研究的重点，目前普遍认为适当剂量的激光照射能增强机体的免疫功能。我们以荷乳腺癌小鼠为实验对象，观察了激光照射荷瘤小鼠脾区对肿瘤生长的抑制作用，并探讨其作用机制。材料和方法１－实验动物和肿瘤瘤源 采用本室
The biological effects produced by laser irradiation on the body have always been the focus of laser biology and laser medical research. Currently, it is generally believed that appropriate doses of laser irradiation can enhance the body’s immune function. We took the mice with liver cancer as experimental subjects to observe the inhibitory effect of laser irradiation on tumor growth in tumor-bearing mice and explore its mechanism of action.
