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 < 相似文献

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。 相似文献
