【摘要】 根据皮肤对日光的反应性对９０例正常人的皮肤加以分型，其中主要是Ⅳ型（８０．１１％），其次是少见的Ⅴ和Ⅲ型。分别测定其对ＵＶＢ和ＵＶＡ的最小红斑量（ＭＥＤ）以及对ＵＶＡ的即刻色素反应（ＩＰ）。双变量相关分析示９０例正常人的ＭＥＤ－ＵＶＢ和ＭＥＤ－ＵＶＡ存在着正相关关系。ＩＰＤ－ＵＶＡ显著低于 ＭＥＤ－ＵＶＡ。与 Ⅱ、Ⅲ型皮肤为主的英国人相比，ＭＥＤ－ＵＶＢ和 ＭＥＤ－ＵＶＡ均显著较高。讨论了皮肤型在光敏性皮肤病和光疗研究中的价值。更多还原

【Abstract】 Ninety normal subjects were determined by the respofnse of the skin to sunlight, and were classified as sun--reactive skin types of Ⅲ, Ⅳ, Ⅴ,most of them were type Ⅳ (80. 11 % ),to the next were types Ⅴ and Ⅲ. The minimal erythema dose (MED) to UVB and UVA,and the immediate pigment darkening reaction(IPD) to UVA radiation were measured for each type. Bivariate correlation analysis showed a positive correlation between the MED UVB and MED- UVA (r= 0. 47d, P＜O. 001 ). The mean IPDUVA was significantly lower than the mean MED--UVA. Both mean MED--UVB and MED--UVA were significantly higher among the subjects in this study in comparison with the English people with skin types Ⅱ and Ⅲ. The validity of sun--reactive skin type in the study on photosensitive skin diseases and phototherapy is discussed.更多还原
