Studies have found that the ultraviolet rays around 310nm have an excellent therapeutic effect on skin diseases, and the erythema effect is relatively small. Combination of UVA or UVB can not enhance its curative effect, and it is easier to produce erythema effect, so the wavelength generated by filtering other wavelengths of ultraviolet light is 311nm The left and right narrowband UVB (narrowband UVB, NB-UVB) can be produced and widely used in the treatment of skin diseases. At present, the domestic UVB medium wave narrowband 311nm lamp can not be manufactured, and the manufacturing process is complicated. The quartz lamp has certain It is required that certain special ingredients added to the tube shell block the emission of ultraviolet rays below 300 and above 320. The special powder inside the tube can emit ultraviolet light with a peak of 311nm. Only when the surface temperature of the lamp tube is 45 degrees, can it produce greater efficiency. The products of imported special lamps are narrow spectrum.
一. Therapeutic function:
1. Improve the body's resistance and stress: By improving the function of the sympathetic nerve-adrenal system, it can regulate endocrine function and improve metabolism. Thereby enhancing the body's ability to resist disease and stress.
2. Improve human immune function: increase the formation of immunoglobulin in the patient's body, activate complement, and strengthen the phagocytic function of white blood cells.
3. Inhibit the proliferation of epidermal cells: ultraviolet rays can reduce the synthesis of DNA that proliferates too fast, thereby preventing the speed of cell classification and proliferation.
4. Damage to epidermal cells: After cell damage, some chemicals can be released, causing inflammation and making skin lesions fade away.
5. Improve the blood circulation of the skin: irradiating ultraviolet rays can expand the skin capillaries, speed up the blood flow, and cause blood stasis in the microcirculation.
6. Stimulate the proliferation and migration of melanocytes. When melanocytes absorb UVB energy, they can also stimulate the activity of tyrosinase, accelerate the oxidation and polymerization of tyrosine, and increase the synthesis of melanin; it can promote the release of keratinocytes Factors that promote the proliferation and differentiation of melanocytes, such as endothelin-1, fibroblast growth factor, etc.; UVB has an immunosuppressive effect; it can also accelerate local blood circulation and make white spots disappear, so it can be used to treat vitiligo.
7. Anti-inflammatory and analgesic: It can limit inflammation, reduce the degree, reduce blisters, and relieve pain, and can treat herpes zoster.
8. Kill bacteria: It can kill bacteria and improve local blood circulation, so that inflammation is limited and the degree is reduced. It is used to treat folliculitis, furuncle, impetigo, erysipelas, etc.
9. Promote wound healing: It can reduce inflammation, reduce secretions, and promote wound healing.
10. Improve the nutritional function of nerves: local irradiation and cervical sympathetic nerve irradiation can improve the nutritional function of nerves, promote blood circulation, and regenerate hair. It can be used to treat alopecia areata.
二. Product advantages:
1. The course of treatment is short, the curative effect is fast, and the total effective is over 90%;
2. No need to take other auxiliary drugs, avoiding the side effects caused by the use of photosensitive drugs;
3. High effective light output intensity, no phototoxic side effects, good safety and tolerability, and no significant impact on normal skin; it is not easy to relapse after curing, and the treatment effect is better than single medication.
4. Avoid the risk of skin burns and carcinogenesis that may be caused by traditional long-wave PUVA and broad-spectrum UVB.
