摘　　要：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。he skin on dorsum of left hands and extensive part of left upper arms in migratory Han andnative Kazak were studied by transmission electron mieroscope at 2800m Geermu altitude at 36.4dcgree of north iatitude. The results in both Han and Kazak showed that 1.There were manyresidual desosomes in horny layers and many mitochondria,endoplasmic reticulum and tonomicro-filaments in the rest layers of the skin.2.The eells of basal laminas were filled with melaningranules.3.Decreased Langerhans.granules and shortened synapse were seen inlangerhans’ cells.4.many filaments and amall vesicles were seen in pedicieser rootiet.5. Fibreconnective tissue in true skin showed proliferation.6. Endothelial cells of small vessels were pro-liferative and vessel lumens were stenotic.7. The changes mentioned above were more serious inmen than women and in dorsum hands than extensive part of upper arms in same age.
