To investigate the effects of MnTE-2-PyP on some markers of antioxidant defence system in asthma mice model.
The animals were divided into four groups: group 1, controls; group 2, injected with ovalbumin, group 3, treated with MnTE-2-PyP, and group 4, treated with ovalbumin and MnTE-2-PyP. The activities of superoxide dismutase, catalase, glutathione peroxidase and nonprotein sulfhydryl groups content (NPSH) were determined in lung homogenate.
The activities of superoxide dismutase and catalase in group 2 decreased significantly as compared to control group. The decrease of the same enzymes in group 4 was lower and significant as compared to group 2. Changes in the glutathione peroxidase activity showed a similar dynamics. The NPSH groups content decreased in group 2. In group 4 this decrease was relatively lower as compared to group 2.
The application of MnTE-2-PyP mitigated the effects of oxidative stress in asthma mice model.
研究 MnTE-2-PyP 对哮喘小鼠模型抗氧化防御系统某些标志物的影响。
将动物分为四组:第 1 组为对照组;第 2 组注射卵清蛋白;第 3 组用 MnTE-2-PyP 治疗;第 4 组用卵清蛋白和 MnTE-2-PyP 治疗。测定肺匀浆中超氧化物歧化酶、过氧化氢酶、谷胱甘肽过氧化物酶的活性以及非蛋白巯基含量(NPSH)。
与对照组相比,第 2 组中超氧化物歧化酶和过氧化氢酶的活性显著降低。与第 2 组相比,第 4 组中相同酶的降低幅度较小且具有显著性。谷胱甘肽过氧化物酶活性的变化呈现相似的动态。第 2 组中 NPSH 含量降低。与第 2 组相比,第 4 组中这种降低相对较小。
MnTE-2-PyP 的应用减轻了哮喘小鼠模型中氧化应激的影响。
