南极环境对考察队员儿茶酚胺含量的影响

报道了中国第八次南极考察队（长城站）队员赴南极前、居留南极及回国后尿、血浆的去甲肾上腺素（ＮＥ）和肾上腺素（Ｅ）含量变化,以探讨考察队员在居留南极期间普遍存在生理和心理变化的物质基础。结果表明：考察队员到达长城站２周时尿中ＮＥ急剧增高（与赴南极前相比Ｐ＜０．０５）,越冬后（居留南极１年２周）ＮＥ大幅度下降（与到达２周时相比Ｐ＜０．００１）,考察结束回国后ＮＥ恢复到赴南极前水平。尿中Ｅ含量在到达南极２周时同样显著升高,且增高幅度大于ＮＥ（与赴南极前比较Ｐ＜０．００１）,越冬后Ｅ水平比到达２周时有所降低（Ｐ＜０．０５）,回国后Ｅ水平没有恢复。提示,儿茶酚胺变化参与综合应激反应过程,Ｅ受心理影响大于生理因素。还发现部分考察队员惧怕抽血,故测定尿儿茶酚胺含量更切实可行。经酸化处理的尿样品在短期内温度（室温）对儿茶酚胺含量影响不大,因此,从南极实地取样返回国内检测及进行南极医学方面的研究完全可行。     

居留南极对考察队员血浆色氨酸及尿中5－羟吲哚乙酸水平的影响

为探讨南极考察队员行为／性格变化的物质基础，观察了驻长城站考察队员血浆色氨酸（Ｔｒｐ）与尿中５－羟吲哚乙酸（５－ＨＩＡＡ）变化。第８次队及第１１次队两批队员变化规律相同，即血浆Ｔｒｐ降低，尿中排出５－ＨＩＡＡ增加，血浆Ｔｒｐ变化较尿排出５－ＨＩＡＡ变化出现早，恢复慢。本文讨论了血浆Ｔｒｐ、尿中５－ＨＩＡＡ变化与行为／性格变化间可能的关系

居留南极对考察队员血中甲状腺素和儿茶酚胺含量的影响

本文报道了中国第 1 6次南极考察队 (长城站 )队员赴南极前和在南极居留一年二周返回国内后 ,血中甲状腺素和儿茶酚胺含量的变化 ,以探讨考察队员在居留南极期间普遍存在的生理和心理变化的物质基础。 1 6次队 1 0名男性考察队员血样分别用化学发光法检测血清总甲状腺素 (TT3、TT4)和促甲状腺激素 (TSH)的含量 ,用高效液相色谱 -电化学法测定血浆中肾上腺素(E)、去甲肾上腺素 (NE)和多巴胺 (DA)的含量。结果表明 :长城站 1 6次队 1 0名男性考察队员赴南极前和在南极居留一年二周返回国内后相比 ,血清中甲状腺素TT3含量无显著性差异 ,TT4含量有非常显著性降低 (P <0 0 1 ) ,促甲状腺激素TSH含量有非常显著性升高 (P <0 0 1 ) ;血浆中的NE、DA含量无显著性差异 ,E的含量有显著性降低 (P <0 0 5 )。南极特殊环境对考察队员甲状腺功能具有减退作用 ;对肾上腺髓质E在血浆中含量有降低作用 ;甲状腺和肾上腺髓质系统共同参与南极综合应激反应 ,以调节机体与外界的平衡。     

Changes of serum thyroid hormone and plasma catecholamine of 16 th and 17 th Chinese Expeditioners in Antarctic environment

The serum thyroid hormone and plasma catecholamine were examined in 18 male and 2 female members of the Chinese Antarctic Expedition (who spent the 2000 or 2001 austral winter at the Great Wall Station) . The changes of serum thyroid hormone i. e. total thyroxine (TT4) and free T4 (FT4) , total triodothyronine (TT3) and freeT3 ( FT3 ) , thyroid stimulating hormone ( TSH ) and plasma catecholamine, including norepinephrine (NE) , epinephrine ( E) and dopamine ( DA ) , were investigated by Chemoluminescence Immunoassay (CLIA) and High Performance Liquid Chromatography with electrochemical detection (HPLC-ECD) . Samples were taken at different time; (1)1 day before departure to Antarctica (16th expedition 1999/12/ 09; 17th expedition 2000/12/06). (2) 1 day after returned to China after living 54 weeks in Antarctica ( 16th expedition 2000/12/25 ; 17th expedition 2001/12/25 ). Comparing the data of before departure and returned, results showed that there was a significant decrease in the contents of TT4 (P <     

南极长城站与北京地区地磁脉动观测资料的对比分析

本文将我国首次南极考察得到的长城站地磁脉动资料与北京地区的同时地磁脉动观测资料作比较。对比分析表明 ,在磁静日中两个地区以平静的脉动为主 ,南极长城站有时出现Pc1 /Pc4- 5脉动 ,北京地区会出现 Pc3脉动。Pi脉动出现很少。但在磁扰日中 Pi型脉动出现次数明显增加 ,还会出现在对应的小时段上。不过长城站的 Pi脉动往往比北京地区强些。     

南极考察队员四项生理指标变化的观察

本文观察了中国南极中山站越冬队员在不同季节的血压、心率、体温和体重的变化,结果表明：在极夜期间,平均收缩压低于对照和回国后的测量值;而舒张压则在极昼时高于回国后的水平;从早晨到夜间（无论极夜或极昼）血压呈逐渐升高的节律性变化。不同季节所测心率的平均值全部低于对照值,在极夜期间降到了全年的最低水平;心率在一天内的变化趋势与血压有很大的相似性。越冬队员体温的变化均低于对照值,但未达到显著的水平;就一天内不同时相而言,早晨的体温均低于其他时相。在中山站,越冬队员每月平均体重与对照值相比均有增加。上述各项生理指标变化的原因有待进一步研究。这些观察与研究为了解人体在极端环境中适应性生理功能的变化提供了基础数据。     

The spatial and seasonal distributions of air-transport origins to the Antarctic based on 5-day backward trajectory analysis

Transport of moisture-bearing air to the Antarctic is one of the important factors that control the mass balance of the ice sheet. Here, we investigate the distribution of air-parcel transport using a backward trajectory analysis over the entire Antarctic ice sheet, based on whether the air parcel was located inside or outside of Antarctica at 5 days before arrival. At this time, we considered the air from outside Antarctica to be moisture rich. Oceanic air was found to dominate in West Antarctica throughout the year, whereas air from inland was more prominently distributed around East Antarctica, especially in summer. In East Antarctica, there was a significant seasonal variation: air from inland dominated in summer, while air of oceanic origin dominated in winter. The distribution of air parcels that came from oceanic/inland sources was similar to the accumulation map (based on satellite data), which indicates that oceanic air parcels could be a substitute for moisture transport to the Antarctic. To determine the future impacts of climate change (e.g., sea level rise), more precise predictions of the variations in the surface mass balance will be required. Our results contribute towards the improved understanding of the spatial distributions of accumulation and aerosols found in Antarctic snow and ice cores.
