The decreased extent of sod / lpo on the o2 intake group was lower than the that on the contrast group significantly , and so were the sod / lpo , gsh - px / lpo of serum , but no significance 5吸氧后，机体红细胞sod mda的下降幅度要比不吸氧组低，并呈显著性。血清中sod mda ， gshpx mda值的下降幅度同样比不吸氧组低，但其差异性不显著。
The activity of cells became weaker and weaker with exposure time . it was conspicuous that uva damaged the activity of cells . the contents of mda upgraded and the contents of gsh - px degraded 结果表明：随着uva照射时间的延长，细胞的活性明显降低，说明uva对细胞的氧化损伤是明显的，其中表现为mda的含量升高、 gsh - px的含量降低。
When bile reflux episode took place , ph showed no relationship with absorbance value ( pxj . 05 ) ; while gastric alkalization occurred , there was also no relationship between them ( px ) . 05 ) 08的时间ph34 。夜间胃内ph值升高（自发性碱化）和胆红素吸收值升高（反流事件）不同时发生，胆红素吸收值升高时， ph值与ba值不相为，一0 067 ， p 0

7 . px express its antioxidant function in three exercise training style groups , and in the endurance training group the function is most obviously which can give a union strong effects in antioxidant with exercise style 服用px对h运动模型大鼠都有较好的抗氧化功效，但对耐力训练、模式的积极作用最为明显，能发挥耐力运动训练和服用px的联合促进功效巾
One internal exercise : the activity of sod and gsh - px in myocardium and muscle is found lowest and the mda content of myocardium is highest , but the mda content of muscle is similar to that of the endurance training and internal training style 运动后48h ，三种运动模式中，一次性间歇运动大鼠心肌和骨骼肌的孤d和付职两种酶的活性最低（ p o刀5人心肌oa水平在三运动模式中最高d
According to an abbreviated version of the report posted on the official website of the municipal government , experts concluded that the southern area of haicang district , the original location of the planned px plant , was too small and inadequate for the diffusion of atmospheric pollution 根据在厦门市政府官方网站公布的环评报告简本，环评专家得出的结论是： “海沧南部空间小，建设px项目的地理条件不适合污染气体的扩散。 ”

( nyse : px ) is the largest industrial gases company in north and south america , fortune 500 company , and one of the largest suppliers worldwide that supplies atmospheric , process and specialty gases , high - performance coatings , and related services and technologies 年销售额达77亿美元的财富五百强企业普莱克斯（纽约证交所交易代码： px ）是一家全球领先的工业气体专业公司，同时也是北美和南美洲最大的工业气体供应商，提供大气气体、工艺气体、特种气体、高性能表面涂料和相关的服务与技术。
The sod activity of serum was higher significantly compared with the no - o2 intake group ( p < 0 . 05 ) after exercises immediately . regarding the extent change of serum gsh - px , the group of o2 intake was higher than no - o2 intake group . it showed : there might be a benefit to the activity of antioxidant enzymes by breathing some hyperoxia o2 after exercise 红细胞sod的30分钟后的值仍高于运动即刻，而不吸氧组的值低于运动即刻，血清sod值同不吸氧组相比显著高于运动即刻t 0刀5人血清hpx值的变化当中，吸氧组的增加变化幅度大于对照组，表明：运动后，吸一定浓度的高压氧可能有利于增加机体运动后抗氧化酶的活力。
Methods : 1 ) 12h after irradiation , the cell cycle of nih3t3 cells was determined by flow of cytometry and the ratio of alternations in p16 gene exon - 2 was evaluated through pcr - sscp . 2 ) the content of mda , the activities of the sod and gsh - px in the supernatant of nih3t3 cells and the cells were measured by detecting kits immediately after irradiation . 3 ) the level of matrix metalloproteinase - 2 ( mmp - 2 ) in hela cells was detected by western - blotting and dot - blotting 2h after irradiation 具体方法为： ( 1 )照射后12h ，收集nih3t3细胞，用流式细胞仪检测各组细胞的细胞周期， pcr - sscp检测抑癌基因p16的变化； ( 2 ) nih3t3细胞照射后立即收集细胞和细胞上清，用试剂盒测量mda含量和sod 、 gsh - px的活性并观察其变化； ( 3 ) western免疫印迹和点杂交法检测照射2h后的各组hela细胞中基质金属蛋白酶- 2 ( mmp - 2 )的表达变化。
