Narrow Band- UVB Therapy for Vitiligo

1. Mechanism

The mechanism of Narrow Band- UVB therapy is the complex biochemical reactions caused by the UVB light. Proved by lots of experiments in laboratory and clinical researches:

1). The radiation of UVB light will led the neuroregulation

2). The UVB light can accelerate the apoptosis of the pathological T-cell, reduce the factors that led the decompose of melanin and protect the activation of melanophore.

3). Promote the secretion of factors to regulate the immunity system.

4). Recall the activity of tyrosinase and promote the formation of melanin.

2. Machines

1) UV7001/UV100 ultraviolet light therapy machine

2) The microcomputer will aid the machine in adjustment of the radiation. The benefits of UV7001/UV100 ultraviolet light therapy machine are precise controlling, repeatable, and comparable.

A. Adaptation diseases：

Patients with age 12 and above.

Vitiligo, Psoriasis, Atopic dermatitis, photosensitive skin diseases, lichen planus, vulgaris acne, mycosis fungoides, pityriasis lichenoides and etc.

B.Contraindication：

Patients with malignant melanoma or had malignant melanoma before

Gestation period, Porphyria, hyperthyroidism, and etc.

2) UV236B/ UV109B ultraviolet light therapy machine

Adaptation area: hands, arms, feet, legs, face and head.

3. The normal reactions after the Narrow Band- UVB therapy:

Blister, redness skin, sunburn pain, itch

The reactions above frequently appear after Narrow Band- UVB therapy, and those reactions will promote the recover of vitiligo. Patients should acknowledge any reactions above to specialist, thus the specialist could adjust the treatment project for the patients.
