对海拔２８００ｍ，北纬３６．４°的格尔木地区的移居汉族和世居哈萨克族，１６～５１岁以上男女的左手背和同侧上臂伸侧皮肤组织进行电镜观察。结果提示：①两个民族表皮角质层内有较多的残存桥粒，其余各层角脱细胞内有较多线粒体，内质网和张力微丝；②基底细胞层充满着黑色素颗粒；③郎格罕细胞内郎格罕颗粒减少和胞质突起变短；④基小脚有较多的锚丝和小泡；⑤其皮层内纤维结缔组织增生致密；⑥小血管内皮细胞增生，管腔变窄；⑦以上几种改变；在同一年龄组男性较女性，左手背较上臂伸侧为著。
Electron microscopy was performed on the left-sided dorsal and ipsilateral upper extensor skin of migrant Han and native Kazakh in Golmud at an altitude of 2800 m and latitude 36.4 ° north and male and female 16- to 51-year-olds. The results suggest that there are more residual desmosomes in the stratum corneum of both ethnic groups and more mitochondria, endoplasmic reticulum and tension microfilaments in the cells of the other layers. The basal cell layer is filled with melanin granules. Langerhans cell reduction in Langerhans cells and cytoplasmic protuberances shorten; ④ base foot more anchor filaments and vesicles; ⑤ cortical fibrous connective tissue hyperplasia; ⑥ small vascular endothelial cell proliferation, narrowing of the lumen ; ⑦ more than a few changes; men in the same age group than women, left upper back extensor side of the arm.
