The present study has investigated the effects of mobile phone electromagnetic radiation (EMR) on fertility in rats. The purpose of this study was to explore the capability of polyphenolic-rich Moringa oleifera leaf extract in protecting rat testis against EMR-induced impairments based on evaluation of sperm count, viability, motility, sperm cell morphology, anti-oxidants (SOD & CAT), oxidative stress marker, testis tissue histopathology and PCNA immunohistochemistry. The sample consisted of sixty male Wistar rats which were divided into four equal groups. The first group (the control) received only standard diet while the second group was supplemented daily and for eight weeks with 200 mg/kg aqueous extract of Moringa leaves. The third group was exposed to 900 MHz fields for one hour a day and for (7) days a week. As for the fourth group, it was exposed to mobile phone radiation and received the Moringa extract. The results showed that the EMR treated group exhibited a significantly decrease sperm parameters. Furthermore, concurrent exposure to EMR and treated with MOE significantly enhanced the sperm parameters. However, histological results in EMR group showed irregular seminiferous tubules, few spermatogonia, giant multinucleated cells, degenerated spermatozoa and the number of Leydig cells was significantly reduced. PCNA labeling indices were significant in EMR group versus the control group. Also, EMR affects spermatogenesis and causes to apoptosis due to the heat and other stress-related EMR in testis tissue. This study concludes that chronic exposure to EMR marked testicular injury which can be prevented by Moringa oleifera leaf extract.
本研究调查了手机电磁辐射(EMR)对大鼠生育能力的影响。本研究的目的是基于对精子数量、活力、运动能力、精子细胞形态、抗氧化剂(超氧化物歧化酶和过氧化氢酶)、氧化应激标志物、睾丸组织组织病理学和增殖细胞核抗原免疫组织化学的评估,探讨富含多酚的辣木叶提取物保护大鼠睾丸免受EMR诱导损伤的能力。样本包括60只雄性Wistar大鼠,它们被分成四个相等的组。第一组(对照组)仅接受标准饮食,而第二组每天补充200mg/kg辣木叶水提取物,持续8周。第三组每天暴露于900MHz场1小时,每周暴露7天。至于第四组,它暴露于手机辐射并接受辣木提取物。结果表明,EMR处理组的精子参数显著降低。此外,同时暴露于EMR并接受辣木叶提取物处理显著提高了精子参数。然而,EMR组的组织学结果显示生精小管不规则、精原细胞数量少、巨大多核细胞、精子退化,且睾丸间质细胞数量显著减少。EMR组与对照组相比,增殖细胞核抗原标记指数有显著差异。此外,EMR影响精子发生,并由于睾丸组织中的热和其他与应激相关的EMR导致细胞凋亡。本研究得出结论,长期暴露于EMR会导致明显的睾丸损伤,而辣木叶提取物可以预防这种损伤。
