| ○要約 (任意): | □ | (英) Secondharmonicgeneration (SHG) microscopy is a powerful tool for in vivo visualisation of collagen fibres in human skin because of its specific collagen selectivity without the need for staining, noninvasiveness and highresolution threedimensional imaging. Although texture analysis of SHG images is a promising method for the quantitative analysis of wellorientated collagen fibre structure in the tendon and cornea, there are few attempts to assess cutaneous ageing. In this study, we applied two texture analysis techniques, namely autocorrelation (2DAC) analysis and twodimensional Fourier transform (2DFT), to evaluate the agedependent changes in reticular dermal collagen fibres in in vivo human cheek skin. Agedependent changes in the reticular dermal collagen fibres of female subjects in their 20s, 40s and 60s clearly appeared in these texture analyses. Furthermore, the parameter from 2DAC analysis showed a significantly higher correlation with skin elasticity measured by a Cutometer®. These results clearly indicate that 2DAC analysis of SHG images is highly promising for the quantitative evaluation of agedependent change in facial collagen fibres as well as skin elasticity. An appropriate texture analysis will help to provide quantitative insight into collagen fibre structure and will be useful for the diagnosis of pathological conditions as well as cutaneous ageing in skin.
