摘要
目的:确定暴露于lena烟雾的妇女的血液中两种氧化应激生物标志物的水平,本地和高海拔居民(3850 m s.n.m)。我们分析了丙二醛(MDA)和静脉血中碳氧血红蛋白(CHOb)的百分比,这也是细胞缺氧的标记物。材料和metodos:叙事,病例系列研究在74名妇女,14至55年了,莉娜和农村地区的接触烟雾Copacabana(拉巴斯市,玻利维亚)3850米s . n . m . seleccion通过调查和一个完整的临床检查。本研究的目的是评估一项研究的结果,该研究的目的是评估一项研究的结果,该研究的目的是评估一项研究的结果,该研究的目的是评估一项研究的结果,该研究的目的是评估一项研究的结果,该研究的目的是评估一项研究的结果。对于描述性统计分析和集中趋势测量,使用SPSS版本18统计包。结果:我们研究了74名年龄在14 - 55岁的女性。MDA平均值为5.5 μmol/L±2,CHOb中位数为1% (p25 - p75: 0.7 - 1.6)。报告燃烧桉树与牛或羊粪便混合物的妇女的平均MDA和中位CHOb为2.5%。结论:在这个高海拔地区,室内空气污染(CAI)增加了氧化应激。在高海拔和低海拔的本地健康人群中,MDA的增加和该生物标志物的差异证明了这一点。此外,使用莉娜与牛或羊粪便混合物的人的MDA和CHOb值更高,因为混合物的危害更大。目的:确定暴露于高海拔地区(3,850米a.s.l)木材烟雾的土著妇女血液中两种氧化应激生物标志物的水平。Malondialdehyde (MDA)水平和carboxyhemoglobin (COHb百分比in venous血液,which is也untold hypoxia biomarker,民工analyzed。材料和方法:descriptive case-series study建都in 74 14与55岁妇女of age微电子木熏烟and coming from the rural area of the Copacabana Municipality(拉巴斯,玻利维亚)at 3,850米a.s.l。was》的通过测量and A physical检查完成。= =地理= =根据美国人口普查,这个县的总面积为,其中土地和(1.2%)水。= =地理= =根据美国人口普查局的数据,这个城镇的土地面积为,其中土地和(1.5%)水。结果:对74名14 - 55岁女性进行了检查。该测试的平均水平为5.5 μmol/L±2 MDA,中值为1% COHb (p25 - p75: 0.7 - 1.6)。过去燃烧桉树和牛或羊混合物的妇女的MDA平均水平较高,COHb平均水平为2.5%。结论:木材烟雾造成的室内空气污染(CAI)增加了生活在高海拔地区的土著人口的氧化应激。这一点可以从MDA水平的增加以及生活在高海拔和海平面上的健康土著人口与生物标记水平的差异中看出。此外,在过去燃烧木材和牛或羊混合物的妇女中,MDA水平和COHb百分比较高,因为这种混合物的危害更大。
