氮氧化物自旋探针的电子顺磁共振(EPR)谱可用于研究生物膜和化学-膜相互作用。最近,我们建立了一种剥离方法来去除角质层(SC)。为了用EPR评价这种剥离方法,并与标准方法相关联,我们通过视觉评分和经皮失水、SC水化和比色法来量化三种表面活性剂的刺激作用,并研究了表面活性物质处理的身体SC(C-SC)和剥离SC(S-SC)在斑贴试验现场的EPR谱测量。5-羟基硬脂酸为自旋标记物。从S-Sc谱得到的有序参数S与C-Sc和TEWL值进行了关联。结果表明,该方法能够评价SC的流动性,并与上述生物工程参数相关。
Electron paramagnetic resonance (EPR) spectra of nitroxide spin probes are useful for studying biological membranes and chemical-membrane interactions. Recently, we established a stripping method to remove stratum corneum (SC) for this purpose. To assess this stripping method with EPR and correlate with standard methods, we quantified the irritant effects of three types of surfactants by measurements of visual score and transepidermal water loss (TEWL), SC hydration and chromametry and studied EPR spectra measurements of surfactant-treated cadaver SC (C-SC) and stripped off SC (S-SC) on patch tested sites. 5-Doxyl stearic acid was the spin label. The order parameter S obtained from the spectra of S-SC correlated with those of C-SC and TEWL values. The results suggest that this method is capable of evaluating the fluidity of SC and correlates with the above bioengineering parameters.
