Abstract

The aim of this study was to measure the alterations in serum selenium (Se), copper (Cu), zinc (Zn), and iron (Fe) concentrations and their carrier proteins, ceruloplasmin (Cp), transferrin (Tf) albumin, and related antioxidant enzyme activities, erythrocyte Cu-Zn superoxide dismutase (Cu-Zn SOD), glutathione peroxidase (GSH-Px), and catalase (CAT) activities in patients with cutaneous leishmaniasis (CL). Erythrocyte Cu-Zn SOD activities, serum Cu concentrations, and Cp levels were found to be significantly higher in the patients group than those of controls. However, GSH-Px and CAT activities and Se, Zn, Fe, and Tf levels were lower in patients than in the control subjects. There were positive important correlation's between Cu-Zn SOD and Cp, Cu-Zn SOD and Cu, Cp and Cu, GSH-Px and Se, and Fe and CAT in the patients group. Our results showed that serum essential trace elements Se, Zn, Cu, and Fe concentrations and their related enzymes Cu-Zn SOD, GSH-Px, and CAT activities change in CL patients. The changes may be a part of defense strategies of organism and are induced by the hormonelike substances.

摘要

本研究旨在测定皮肤利什曼病(CL)患者血清中硒(Se)、铜(Cu)、锌(Zn)和铁(Fe)浓度及其载体蛋白、铜蓝蛋白(Cp)、转铁蛋白(Tf)、白蛋白以及相关抗氧化酶活性,即红细胞铜锌超氧化物歧化酶(Cu-Zn SOD)、谷胱甘肽过氧化物酶(GSH-Px)和过氧化氢酶(CAT)的活性。结果发现,患者组的红细胞Cu-Zn SOD活性、血清Cu浓度和Cp水平显著高于对照组。然而,患者的GSH-Px和CAT活性以及Se、Zn、Fe和Tf水平低于对照组。在患者组中,Cu-Zn SOD与Cp、Cu-Zn SOD与Cu、Cp与Cu、GSH-Px与Se以及Fe与CAT之间存在显著正相关。我们的结果表明,CL患者血清中必需微量元素Se、Zn、Cu和Fe的浓度及其相关酶Cu-Zn SOD、GSH-Px和CAT的活性发生了变化。这些变化可能是机体防御策略的一部分,由类激素物质诱导产生。
