Narrow-spectrum medium-wave ultraviolet therapy instrument (NB-UVB) lamp wavelength of 320nm-290nm is the most active part of UV biological activity. Studies have found that UVB around 310nm has the best therapeutic effect on skin diseases, and the erythema effect is relatively small.
Indications.
①Unusual psoriasis
② Vitiligo
③Chronic eczema
④Neurodermatitis
⑤ atopic dermatitis
⑥Palmoplantar pustulosis
⑦Pityriasis rosea
⑧Plaque baldness
⑨ Parapsoriasis
⑩Chronic skin ulcers
Therapeutic functions.
1.Improve the body’s resistance and stress capacity: by improving the function of sympathetic-adrenal system to regulate endocrine function and improve metabolism. Thus, it enhances the body’s resistance to disease and stress capacity.
2.Improve human immune function: It can increase the formation of immunoglobulin in the patient’s body, which can activate the complement and strengthen the phagocytosis of leukocytes.
3.Inhibit the proliferation of epidermal cells: UV light can reduce the synthesis of deoxyribonucleic acid that proliferates too fast, thus stopping the rate of cell classification and proliferation.
4, improve the blood circulation of the skin: exposure to ultraviolet light can make the skin capillaries dilate, so that the blood flow is accelerated thus making the phenomenon of microcirculation blood stasis.
5, stimulate the proliferation and migration of melanocytes, when melanocytes absorb UVB energy, can also stimulate tyrosinase activity, accelerate the oxidation and polymerization of tyrosine, so that melanin synthesis increases; can promote the release of keratin-forming cells pro-melanocyte proliferation and differentiation factors such as endothelin-1, fibroblast growth factor, etc.; UVB has immunosuppressive effects; can also accelerate local blood circulation, so that UVB has an immunosuppressive effect; it can also accelerate local blood circulation and make the white spots disappear, so it can be used to treat vitiligo.
6, anti-inflammatory and pain relief: it can make the inflammation limited, the degree reduced, the blisters reduced, the pain reduced, and can treat herpes zoster.
The advantages of narrow spectrum medium wave ultraviolet treatment instrument.
1.Short course of treatment, fast curative effect, the total effective up to 90% or more;
2, no need to take other auxiliary drugs, to avoid the use of photosensitive drugs brought about by the side effects;
3, effective light output intensity, no phototoxic side effects, good safety and tolerability, no significant impact on normal skin; not easy to relapse after cure, better than a single drug treatment;
4, to avoid the traditional long-wave PUVA and broad-spectrum UVB may lead to skin burns and the chance of cancer.
