The Abstracts of the 12th Congress of the Japan Society for Laser Reproduction(JaSLaR)

摘要

Dr. Maiman successfully created laser light oscillation using ruby crystal in 1960. Therefore, he was actually an inventorof laser therapy technology. Since then, laser technology was used for industry, telecommunication and military usagein the United States and Soviet Union. Adoption of laser therapy in the medical field started early in 1961, one year laterfrom Dr. Maiman’s invention. Laser therapy was used for surgery of retinal detachment at first and then, in 1970, lasertherapy was used for urinary calculus. Application of laser therapy in Japan started from ophthalmology around 1980.Nowadays many doctors are using laser therapy in many medical fields in Japan. When we see a story about LLLT (Lowreactive level laser treatment), as early as the middle of the 1960s, Hungarian surgeon Endre Mester noticed animprovement of wound healing when using LLL. Since then the number of scientific studies about the biological effectof laser light irradiation has been growing steadily. Numerous scientific organizations have been looking into this matterfor years in the fields of wound healing, chronic orthopedic problems like osteoarthritis or spinal diseases, acute strainslike tenosynovitis, skin problems, allergic reactions and other problems. These studies have encouraged us to enlargethe field from our therapeutic experience in the biological effects of laser therapy. In the 1980th, they were spurred byearly reports about the positive effects of laser light on nerve cells and nerve injuries. The perceptible and measurablepositive results, getting more and more distinct, effective treatments of diseases with LLLT have encouraged to developLLLT for the treatment of many other diseases including infertility. Many reports confirmed the fundamental efficacy oflaser light which was experienced as subjectively positive and which at the same time was objectively measured.Hippocrates said that the gods had set the diagnosis before any treatment. However, before any therapy by Low-LevelLaser light there should be the effort to understand action mechanisms of this therapy on the patients. Also, we shouldtell the patients what they know, so that their process of healing is further supported. Light is commonly perceived aspositive image on the people for a long time, even from the ancient period. Probably human being sees that light has aperceivable biological effect on our body. The first sunbathing in spring, pleasantly going to sleep in a deckchair in thewarm sunshine, the hunger for more and more sunlight from winter to spring and from spring to summer, the disappointment if the weather is worse than we would like, the joy if the sun comes out again, but also the filling of ourhunger for the sun when we have had enough light. On the other hand, we usually experience lack of light as tiringand unpleasant, and this even more distinctly the longer the lack of light continues. But in spite of everyone perceivingand experiencing the effect of light on one’s body, there is no commonly accepted knowledge about it. Therefore, thequestion of the biological effect of light on our body is quite justified. Thousands of clinically documented healing successes and patients’ reports give evidence for the biologically positive bio-stimulating effects of light or LLL. On theother hand, some people worry about the dangerousness of light. Only the small range of wavelengths of the ultraviolet(invisible for us) part of natural solar radiation is potentially dangerous for us. The whole of the visible part of naturalsolar radiation from the visible violet wavelength from 400 nm are all biologically completely harmless. Every livingbeing can live in this quality of light for years and decades without suffering any harm. In millions of years our biosphere has developed under the continuous physical effect of light on the living, but organic structures of all livingbeings survived without suffering any harm. This is why I would like to introduce you light therapy including LLLT withreference to the history of evolution of human beings under the sun beam.
