】对１２名冬泳爱好者安静时和一次定量冬泳后红细胞ＳＯＤ活力及血浆ＭＤＡ含量进行了测定。结果显示：冬泳锻炼可以提高老年人红细胞ＳＯＤ的活力，增强红细胞抵御氧自由基损伤的能力。  相似文献   

2，4-二羟基苯乙酮合水杨酰肼化合物的生物活性及对抗氧化酶活性的影响     

李居宁 《荆门职业技术学院学报》2008,23(6)

用2,4-二羟基苯乙酮合水杨酰肼配体系列化合物来处理水稻幼苗,分析它们对细胞活性的影响及对抗氧化酶系的超氧化物歧化酶(SOD)、过氧化物酶(POD)活性的影响.生物活性测试的结果表明,部分化合物在浓度为0.1～100 ppm时能促进细胞的活性;SOD酶和POD酶活力测试的结果表明,部分化合物在浓度为0.1～100 ppm时对两种氧化酶的活性有不同程度的促进作用.这说明化合物对水稻幼苗生长的影响可能是通过对水稻幼苗SOD酶和POD酶的活力影响的结果.  相似文献   

Differential pH sensitivity of tissue superoxide dismutases     

Samir P Patel  Surendra S Katyare 《Indian journal of clinical biochemistry : IJCB》2006,21(2):129-133

Superoxide dismutase (SOD) activities in the human and rat RBCs and rat liver, kidney, brain and heart mitochondria as well as cytosolic fractions were determined by the pyrogallol assay procedure with slight modifications. Measurements were carried out in 0.1 M potassium phosphate buffer pH 8.0 and 9.2 to assess the pH stability of the SODs from various systems. Under these conditions the SODs from different systems including RBCs exhibited differential pH stability i.e. they displayed differential susceptibility at pH 9.2. Even in a given tissue, the mitochondrial and cytosolic SODs contents show a tissue-specific pattern. Our results also suggest that measurements carried out at pH 8.0 may give more realistic estimates of SOD activities.  相似文献
