Abstract

The structure of hairs from three patients with sulphur-deficient hair, trichothiodystrophy, has been studied by light, plane-polarizing and scanning electron microscopy. Severe cuticular and secondary cortical degeneration was evident along almost the entire length of the hair shaft, with cuticle loss, trichorrhexis nodosa formation and trichoschisis. The severity of these changes varied between patients. The role of the cuticle in protecting hair from environmental damage is discussed.

摘要

通过光学显微镜、平面偏振显微镜和扫描电子显微镜对三名患有硫缺乏性毛发、毛发硫营养不良的患者的毛发结构进行了研究。在毛干几乎整个长度上都明显存在严重的表皮和次级皮质变性，伴有表皮脱落、结节性脆发形成和毛发分裂。这些变化的严重程度在患者之间有所不同。文中讨论了表皮在保护毛发免受环境损伤方面的作用。
