Abstract

This study was investigated to observe morphological changes of two pre-astronauts' hair, male and female by electron microscopy and to analyze its tensile strength by using rheometer. The surface of those two pre-astronauts' hair, which were very rough and irregular, contained separated scales and destroyed remnants of cuticular cells. Also, there were many holes on the cytoplasm of the cuticular cells which forms the cuticle layer. The destruction begins when the endocuticle where the holes form gets destroyed. And then, The tensile strength of female pre-astronaut's hair was 14.60 mm which is 10% reduced, compared to that of the normal healthy hair. Thus, this result thought to be due to the prolonged change of the biorhythm and psychological instability of the pre-astronauts.

본 연구는 우주비행 훈련 중인 남녀 예비우주인의 모발을 채취하여 모발의 형태적 변화를 전자현미경을 사용하여 관찰하였고 인장강도 특성을 인장강도기를 사용하여 분석하였다. 남성과 여성 두 예비우주인의 모발 표면은 매우 거칠고 불규칙한 모양을 하고 있었다. 예비우주인들의 모발표면에는 파괴된 큐티클세포의 잔유물이 지저분하게 붙어 있었고, 비늘이 분리되어 있었다. 그리고 큐티클층을 이루고 있는 큐티클세포의 세포질에는 많은 구멍을 형성하고 있었다. 모발 표면에서 큐티클세포의 부서짐은 이들 구멍들이 형성된 부위인 내큐티클이 파괴되면서 나타났다. 그리고 여성 예비우주인 모발의 인장강도는 14.60mm로서 건강모발과 비교하였을 때 약 10% 감소한 것으로 나타났다.
