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。     

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。     

极地驻留时间对认知功能的影响

记忆、空间认知等基本认知功能是影响考察人员能否在南极高寒、单调、孤立、封闭的极端环境下完成复杂任务的基础认知能力.关于极地驻留时间长短对认知功能的影响尚缺乏专门的研究.本文通过计算机记录反应时技术,追踪自度夏到越冬中期,中国南极第25次队长城站越冬人员短时再认、记忆搜索、空间认知能力随驻留时间延长发生的变化.结果表明:...

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 <     

中国南极维多利亚地新站气象特征分析

中国南极新站选择在维多利亚地特拉诺瓦湾难言岛上进行建设,其气象环境状况是开展科学研究的基础工作,也是考察队员生命安全保障的基础资料。因此,通过2013年度难言岛气象站的观测资料,结合附近地区历史气象资料,对该区域气象要素特征进行了分析。结果表明:(1)由于地处罗斯海与东南极冰盖交界处,难言岛年均气压为987.8 h Pa,与中山站非常接近;(2)年均温为-16.1℃,最低气温为-39.3℃,且冬季气温波动较大,标准差可达±6.0℃;(3)年均相对湿度为42.1%,年均比湿为0.6 g·kg-1且冬季比湿极低,空气非常干燥,降水量非常低;(4)盛行风向为WNW,5—7级风出现频率超过50%,但夏季风速明显低于冬季风速,一般不超过8.0 m·s~(-1),有利于中国在夏季开展工程建设和补给;(5)难言岛年总辐射量为3 342.8 MJ·m~(-2),明显低于中山站,但两站反照率非常接近。     

南极威尔克斯地SGR钻孔处雪冰转化过程中的密度变化特征

本文着重描述了SGR钻孔处冰盖上的积雪在密实化过程中的特征变化,并对该过程进行了分段的和全面的回归分析.结果表明,冰盖密度随深度增大,但增长幅度随深度减小.作者提出密度变化减小度的概念.计算得出的所研究冰芯钻取点的密度变化减小度为-0.15kg/m~3·m~2,粒雪成冰前的密实速率平均值为4.08kg/m~3·a.本文得到的冰盖密度变化“临界点”与以往报道的有所不同.分析这一现象时,作者强调当积雪还在活动层时冰盖温度的影响,并以此解释密度剖面的异常变化以及离差的回升.特别指出,积雪的密度变化具有气候学意义,它在一定程度上能够反映出积雪形成及变化过程中气候变化的某些信息.本文由密度变化确定的钻孔点雪冰转化深度为50米.     

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.
