function of uv phototherapy
Type:Uv phototherapy Time:2018-08-29 22:07:02After low-dose UV irradiation, the synthesis of DNA and RNA is first inhibited and then accelerated, which promotes the growth of granulation, epithelial tissue and wound healing. It is used to treat various pressure ulcers. In addition, ultraviolet radiation can also expand blood vessels, accelerate blood flow, improve local blood circulation, strengthen local nutrition, and improve
The body's immune function. A large number of animal experiments and clinical practice have shown that low-energy laser irradiation has good anti-inflammatory and tissue repair functions, can expand blood vessels, improve microcirculation, increase oxygen carrying capacity of red blood cells, enhance immunity, and stimulate the phagocytosis of macrophages. The ability and regeneration of granulation tissue to promote wound healing. In recent years, foreign scholars have found that semiconductor lasers are superior to other low-energy lasers in their anti-inflammatory and anti-infective effects. The mechanism of action is mainly to reduce the permeability of blood vessel walls, reduce inflammation, oozing, edema, and activate macrophages. The function of the system improves the body's whole body and local immunity, and plays an anti-inflammatory and anti-infective role. Laser irradiation promotes the formation and growth of new blood vessels, and increases the content of cellular ribonucleic acid and glycogen, and fibroblast proliferation. The growth of granulation tissue leads to the regeneration of new epithelial tissue. The semiconductor laser can also increase the balance of DNA content in the RNA and nucleus of the cytoplasm, and promote protein synthesis, thereby stimulating wound healing. Ultraviolet combined with semiconductor laser treatment of hemorrhoids, antibacterial and anti-inflammatory effect, can accelerate the speed of wound healing, and is not easy to repeat, is effective and effective for the treatment of hemorrhoids, and the operation is simple and safe, it is worthy of clinical promotion, combined application. However, the cure rate for mild to moderate acne is higher and the healing time is faster, suggesting that clinical care should be discovered in time and treated as soon as possible.
