正常新疆维吾尔族人头发的扫描电镜观察

SCANNING ELECTRONMICROSCOPE OBSERVATION OF HAIR FROM HEALTHY PECOPLE OF THE UIGUR NATIONALITY IN XINJIANG

本文应用扫描电子显微镜对新疆维吾尔自治区南部地区12名(6女,6男),年龄在17岁至20岁之间的维吾尔族人不同部位的头发进行了初步观察研究。发现头发呈圆柱形,毛小皮鳞片呈叠瓦状。但鳞片排列方式、紧密度及形态因个体及部位不同而异。根据毛小皮排列方式可分为三型:即平行型,交错型及混合型,又根据毛小皮排列的紧密度分为密型和疏型。毛干的直径因个体不同大致可分为粗发和细发,粗发毛小皮单位距离内的层数大于细发,毛小皮排列多呈平行线。细发毛小皮排列多呈交错、混合型。

The authors have studied 36 sections of hair with a scanning electronmicroscope from different parts of the scalp. The materials were taken from 6 healthy men and 6 healthy women between the ages of 17 and 20 all of Uigur nationality in Xinjiang. The surface ultrastructure of the cuticle in the hair shaft are distinctly shown. The cuticle are in an imbricative arrangement. The arrangements of imbrication are roughly. Divieded into 5 types. Specifically, parallel, cross, mixed dense and loose.There is no difference observed among different sexes.
