高山(海拔2500米以上)对人体的影响不仅是缺氧,而且有寒冷、风力、大气辐射等因素。鼻粘膜首先经受其影响,发生功能和形态的变化。作者检查了18名参加高山考察的20～35岁的男子,他们在高山(海拔3375米)居住14天到30天,其中4人有适应障碍的症状。从下鼻甲前缘向后0.5～1cm 处取活检标本0.2×0.2cm,用光学显微镜、透射电镜和扫描电镜观察。在高山居住14天后,主诉鼻干燥,阻塞,个别人鼻出血,肉眼检查鼻粘膜充血水肿,有时有痂皮。半薄切
Alpine (2500 meters above sea level) on the human body is not only hypoxia, but also cold, wind, atmospheric radiation and other factors. Nasal mucosa first undergoes its effects and undergoes functional and morphological changes. The authors examined 18 men aged 20 to 35 who participated in the mountain expedition who lived in the high mountains (3375 meters above sea level) for 14 days to 30 days, of whom 4 had symptoms of accommodation disorder. From the inferior turbinate front edge 0.5 ~ 1cm biopsy specimens taken 0.2 × 0.2cm, with optical microscopy, transmission electron microscopy and scanning electron microscopy. After 14 days in the mountains to live, the main complaint of dry nose, obstruction, individual nosebleeds, macroscopic nasal mucosal congestion and edema, and sometimes the crust. Half thin cut
