短跑运动对肝脏和骨骼肌中谷胱甘肽表达的影响     

李靖 《宜春学院学报》2012,34(8):124-127

急性无氧运动促进氧化应激。然而,之前的研究指出高强度短跑训练能减弱氧化应激效应。假设还原型谷胱甘肽(GSH)的上调在防护短跑训练中的氧化应激起重要作用。33只大鼠随机分为3组:对照组;急性运动组和训练组。训练组大鼠参与高强度训练,每周2天,共12周的跑台运动。在训练期结束,训练组和急性运动组大鼠进行一次高强度短跑。对照组大鼠不运动。用分光光度计测定比目鱼肌和趾长伸肌(EDL)以及肝脏的GSH和氧化型谷胱甘肽(GSSG)浓度。与对照组相比,急性运动后,比目鱼肌和EDL的GSH浓度显著下降,同时,两组肌肉中的GSSG浓度明显增加。12周短跑训练后,与对照组相比,两组肌肉中的GSH没有显著差异。同时肌肉中GSSG浓度显著增加。数据显示,由于高强度短跑导致骨骼肌恢复GSH水平。但是,不能说明GSH的上调是由肝脏输入的。  相似文献

Review:Anaerobic ammonium oxidation for treatment of ammonium-rich wastewaters

The concept of anaerobic ammonium oxidation (ANAMMOX) is presently of great interest.The functional bacteria belonging to the Planctomycete phylum and their metabolism are investigated by microbiologists.Meanwhile,the ANAMMOX is equally valuable in treatment of ammonium-rich wastewaters.Related processes including partial nitritation-ANAMMOX and completely autotrophic nitrogen removal over nitrite (CANON) have been developed,and lab-scale experiments proved that both processes were quite feasible in engineering with appropriate control.Successful full-scale practice in the Netherlands will ac-celerate application of the process in future.This review introduces the microbiology and more focuses on application of the ANAMMOX process.  相似文献
