Abstract

The preservative condition and ultrastructure on the mummified hair collected from newly found female mummy in Paju, were investigated by using scanning and transmission electron microscopes. The female mummy was found in september, 2002 during the traditional reburial process for the buried ones. The hair of 16th century mummy showed very intact appearances during observation with electron microscope. And the structures of the cortex, medulla and cuticle were well preserved. The cuticle layer was easily discernable, which are composed of six to seven cuticular cells. Each cuticular cells surrounded and thus seperated from its neighbors by intercellular membrane complex. In the cortex, many macrofibrils and some melanin granules between them were observed. We observed well preserved rod form macrofibrils running parallel along the direction of hair shaft. Especially, melanin granules were aggregated in the cortex which was adjacent to the cuticlu layer. As to the cause for the well-preservation of 440 year old hair sample, the presence of surface coat on the hair, which are composed of various materials. As calcium was included in the surface coat in Electron Dispersive X-ray Spectroscopy (EDS), the hardening process of the surface coat by calcium might inhibit the water or microorganism infiltration into the hair.

본 연구는 2002년 9월 묘지 이장 과정 중에 경기도 파주에서 발견된 여성미라 머리카락의 미세구조와 보존상태를 투과 및 주사전자현미경으로 관찰하였다. 16세기에 만들어진 미라의 머리카락은 완벽한 상태로 관찰되었다. 머리카락의 큐티클층과 피질 및 수질도 분해되거나 부서지지 않은 상태로 보존되어 있다. 큐티클층은 윤곽이 뚜렷하게 구별되는데 이 층은 $6{\sim}7$개의 큐티클세포들로 구성되어 있다. 각각의 큐티클세포는 세포사이막복합체에 의해서 견고하게 부착되어 있다. 피질은 거대원섬유들에 의해서 채워져 있으며 이들 사이에 멜라닌과립들이 산재되어 있다. 막대모양을 하고 있는 거대원섬유는 머리카락의 종축을 따라 평행하게 배열되어 있다. 특히, 피질에서 멜라닌과립은 큐티클층과 인접한 부위에 집중적으로 분포되어 있다. 440년 동안 머리카락이 보존된 원인은 머리카락을 피복하고 있는 다양한 물질들에 의해서 일어났는데, 피복물질을 에너지분산분광분석기로 분석한 결과 칼슘성분이 검출되었다. 머리카락 표면을 덮고 있는 칼슘이온은 머리카락에 수분이나 미생물 등의 접촉을 억제하는 역할을 하는 것으로 사료된다.
