Abstract

OBJECTIVE

The effects of electromagnetic radiation (EMR) produced by a third-generation (3G) mobile phone (MP) on rat brain tissues were investigated in terms of magnetic resonance spectroscopy (MRS), biochemistry, and histopathological evaluations.

METHODS

The rats were randomly assigned to two groups: Group 1 is composed of 3G-EMR-exposed rats (n = 9) and Group 2 is the control group (n = 9). The first group was subjected to EMR for 20 days. The control group was not exposed to EMR. Choline (Cho), creatinin (Cr), and N-acetylaspartate (NAA) levels were evaluated by MRS. Catalase (CAT) and glutathione peroxidase (GSH-Px) enzyme activities were measured by spectrophotometric method. Histopathological analyses were carried out to evaluate apoptosis in the brain tissues of both groups.

RESULTS

In MRS, NAA/Cr, Cho/Cr, and NAA/Cho ratios were not significantly different between Groups 1 and 2. Neither the oxidative stress parameters, CAT and GSH-Px, nor the number of apoptotic cells were significantly different between Groups 1 and 2.

CONCLUSIONS

Usage of short-term 3G MP does not seem to have a harmful effect on rat brain tissue.

摘要

目的

通过磁共振波谱(MRS)、生物化学和组织病理学评估,研究第三代(3G)移动电话(MP)产生的电磁辐射(EMR)对大鼠脑组织的影响。

方法

将大鼠随机分为两组:暴露于 3G-EMR 的第 1 组(n = 9)和对照组(n = 9)。第 1 组接受 EMR 照射 20 天。对照组未暴露于 EMR。通过 MRS 评估胆碱(Cho)、肌酸(Cr)和 N-乙酰天冬氨酸(NAA)水平。通过分光光度法测量过氧化氢酶(CAT)和谷胱甘肽过氧化物酶(GSH-Px)的酶活性。进行组织病理学分析以评估两组脑组织中的细胞凋亡。

结果

在 MRS 中,第 1 组和第 2 组之间 NAA/Cr、Cho/Cr 和 NAA/Cho 比值无显著差异。第 1 组和第 2 组之间的氧化应激参数 CAT 和 GSH-Px 以及细胞凋亡的数量也无显著差异。

结论

短期使用 3G MP 似乎对大鼠脑组织没有不良影响。
