Effects of lead polluted water on activities of superoxide dismutase, peroxidase and ultrastructure in leaves of Trapa bicornis seedlings 铅污染对菱幼苗SOD、POD及叶细胞亚显微结构的影响
Results CCC could reduce the contents of lead in blood, brain, liver and femur significantly, decrease the level of maleicdialdehyde ( MDA), increase activities of superoxide dismutase ( SOD), glutathione peroxidase ( GSH-Px) and total antioxidative capacity ( T-AOC) in liver markedly. 结果羧甲基壳聚糖钙能显著降低染铅小鼠血液、全脑、肝脏、股骨铅含量,降低染铅小鼠肝脏中MDA水平,显著升高SOD、GSH-Px、T-AOC活性,增加股骨钙含量。
[ Objective] To investigate the effect of lead exposure during pregnancy on the levels of nitric oxide ( NO) and malondialdehyde ( MDA), superoxide dismutase ( SOD) in the placenta. 目的探讨孕期铅暴露对鼠胎盘组织NO及丙二醛/超氧化物歧化酶(MDA/SOD)水平的影响。
The present paper has studied accumulation of copper and lead in fish tissues and lipid superoxide by interaction of the mixture-metals. 采用室内暴露实验方法,研究了混合重金属离子相互作用对Cu、Pb在鱼组织中吸收、积累以及其诱导的脂质过氧化作用。
OBJECTIVE: To observe the effects of Cili juice enriched with SOD ( CLJES) on lead excretion, activity of superoxide dismutase ( SOD) in erythrocytes, plasma lipid peroxidation ( LPO) and immune function in experimental lead poisoning animals. 目的:观察强化SOD刺梨汁(简称SOD刺梨汁)对铅中毒动物的驱铅作用,及其对铅中毒动物体内超氧化物歧化酶(SOD)、过氧化脂质(LPO)和免疫功能的影响。
In recent years, many studies have found that sevoflurane preconditioning on myocardial ischemia reperfusion has an important protection role, and lead to myocardial ischemia and hypoxia in the myocardium superoxide overproduction is an important source of myocardial injury. 近年来,许多研究发现七氟醚预处理对心肌缺血再灌注有着重要的保护作用,而心肌缺血缺氧导致的心肌内超氧阴离子过度产生是引起心肌损伤的重要来源。
