Mechanism of treatment effect of low-energy laser irradiation

The mechanism of treatment effect of low-energy He-Ne laser irradiation in patients with precancerous changes of gastric mucosa has been studied. There has been found that the treatment effect of low-energy laser irradiation depends on the initial level as well as on the change in the levels of hormonal, immune systems, processes of peroxide oxidation of lipoids and antioxidant activity. The positive clinico-morphological effect in 65.1% of patients with precancerous changes of gastric mucosa associates with the influence of intravascular laser irradiation on the nonspecific mechanisms of adaptation and the factors of immunologic defence.© (1996) COPYRIGHT SPIE--The International Society for Optical Engineering.
