BACKGROUND
Many reports have been released to assess skin types, skin colors and cutaneous sensitivity to broad band UVB or UVA.
OBJECTIVE
This study was performed to investigate the usefulness of skin type and skin color as the parameter of narrow band UVB (NBUVB) sensitivity.
METHODS
The minimal erythema dose (MED) of 40 psoriasis patients was investigated by irradiating several doses ranging from 200 to 1500 mJ/cm2. Before phototesting, the skin color of buttock was measured with a tristimulus colorimeter.
RESULTS
The median and mode value of MED of NBUVB was 950 mJ/cm2. Skin type was well correlated with the MED and there was a significant relationship between the L* value and MED, but not for the a* and b* values.
CONCLUSION
The MED value of NBUVB in our study is a basic data to set the phototherapy protocol. Our result showed that skin type and L* value might be useful for predicting the sensitivity to NBUVB irradiation.
背景
已经发布了许多报告来评估皮肤类型、肤色以及皮肤对宽带UVB或UVA的敏感性。
目的
本研究旨在探讨皮肤类型和肤色作为窄带UVB（NBUVB）敏感性参数的有用性。
方法
通过照射200至1500 mJ/cm²的几个剂量，研究了40例银屑病患者的最小红斑量（MED）。在光测试前，用三色刺激色度计测量臀部皮肤颜色。
结果
NBUVB的MED中位数和众数值为950 mJ/cm²。皮肤类型与MED密切相关，L值与MED之间存在显著关系，但a和b*值则不然。
结论
我们研究中NBUVB的MED值是制定光疗方案的基础数据。我们的结果表明，皮肤类型和L*值可能有助于预测对NBUVB照射的敏感性。
