大强度运动对机体免疫功能的影响 总被引:3,自引:0,他引:3
徐玉娥 《山西师大体育学院学报》2006,21(2):123-124
大强度运动可降低机体的免疫功能,可能与运动时的应激反应、运动时红细胞免疫力降低、运动性贫血、自由基生成增多、线粒体变性以及运动时的营养消耗有关。 相似文献

建立一种灵敏度高和特异性好的直接竞争ELISA法来定性和定量检测牛乳中α-乳白蛋白(α-LA).通过使用牛乳α-LA多次免疫新西兰大白兔制备多克隆抗体,并采用过碘酸钠氧化法制备辣根过氧化物酶(HRP)标记的α-LA,建立检测α-LA的直接竞争ELISA法.所制备的多克隆抗体特异性较高,无明显交叉反应,效价为1:80 920.酶标抗原的标记率达66.67%.直接竞争ELISA法标准曲线相关系数为0.998 57,回收率在86.00%~117.50%之间,重复性高,变异系数<5%.与国标电泳方法进行样品检测比较,结果显示该方法可有效地用于食品中α-LA的快速定性和定量检测. 相似文献

传染性非典型肺炎可能由变异的冠状病毒引起,尚无有效的治疗药物,因而人体自身的免疫力强弱与该病的染病和预后关系密切。本论述了体育锻炼与人体免疫力的关系,并对锻炼身体的方法和注意事项作了详细的介绍。 相似文献

最新研究表明,超量运动中Th2细胞因子IL-4、IL-6、IL-10及TNF-α水平的明显上调及应激激素的大量分泌,造成Th1和Th2之比失衡,进而导致体液免疫功能增强、细胞免疫功能相对低下,是继慢性运动后感染性疾病发病率增高的主要原因.而运动应激以及运动中损伤则是免疫系统应答的激活因子.诱导性协同刺激分子在运动后活化T细胞上的表达及其对Th2细胞的分化诱导,表明了它在运动免疫应答中重要而独特的作用. 相似文献

To examine both mental and physical health profiles of children diagnosed as maltreated in the community, we studied diagnoses in the electronic health records (EHRs) of youth assigned maltreatment-related diagnoses (N = 406) and well-matched youth without a maltreatment-related diagnosis (N = 406) during a four-year period in a large healthcare system that covers eight hospitals and over 40 clinics. Data extracted automatically from the EHRs was supplemented by manual chart review. The odds of the maltreated group being assigned a code for mental illness was 2.69 times higher than the odds for the comparison group, with large differences in mood and anxiety disorders and suicidality. The odds of having an injury or poisoning diagnosis were 3.45 times higher in maltreated than in comparison youth. Maltreated youth were also less likely to have been immunized. Nevertheless, contrary to our hypothesis, maltreated youth had significantly lower rates of diagnoses across almost all major physical disease categories assessed and did not differ from comparison youth in terms of body mass index (BMI). Furthermore, maltreated youth were assigned fewer diagnoses than comparison youth whether they came in for at least one preventive visit or not. Findings suggest a need for health care professionals to be prepared to address the high rates of mental disorders in maltreated youth, to be more vigilant about possible physical disorders in this population, and to take greater advantage of opportunities to immunize these youth. 相似文献
