In the present study, the effect of 900 MHz radiation exposure on blood biochemical and reproductive parameters was evaluated in adolescent rats. Male albino Wistar rats (8-10 weeks of age) were exposed to 900 MHz radiation (1hr/day, power density - 146.60 µW/cm2) from a mobile phone for 28 days. On 29th day the animals were euthanized and malondialdehyde (MDA), total antioxidants (TA) levels and Glutathione-S transferase (GST) activity were studied in the blood. Reproductive parameters such as total sperm count, percentage of non-motile sperms, and sperm morphology were determined. Testes sections were stained with H(et)E staining and their cellular integrity was evaluated. Caspase-3 activity in the testes was also determined. MDA concentration was increased but TA levels and GST activity were not found to be different in 900 MHz group compared to controls. Sperm motility was found to be slightly reduced in 900 MHz group. Percentage of abnormal sperm was significantly elevated in 900 MHz group. Additionally, loss of germ cells particularly spermatocytes and spermatids was found in the testes of 900 MHz group. Testes caspase-3 activity was slightly elevated in 900 MHz exposed rats. Chronic 900 MHz exposure induced oxidative damage in the blood and lead to alterations in reproductive parameters in rats (Fig. 4, Ref. 33).
在本研究中,评估了900兆赫兹辐射暴露对青春期大鼠血液生化参数和生殖参数的影响。雄性白化Wistar大鼠(8 - 10周龄)每天接受来自手机的900兆赫兹辐射(每天1小时,功率密度 - 146.60微瓦/平方厘米),持续28天。在第29天,对动物实施安乐死,并研究血液中的丙二醛(MDA)、总抗氧化剂(TA)水平和谷胱甘肽 - S转移酶(GST)活性。测定生殖参数,如精子总数、不活动精子百分比和精子形态。对睾丸切片进行苏木精 - 伊红(H&E)染色,并评估其细胞完整性。还测定了睾丸中的半胱天冬酶 - 3活性。与对照组相比,900兆赫兹组的MDA浓度升高,但TA水平和GST活性未发现差异。900兆赫兹组的精子活力略有降低。900兆赫兹组的异常精子百分比显著升高。此外,在900兆赫兹组大鼠的睾丸中发现生殖细胞尤其是精母细胞和精子细胞减少。暴露于900兆赫兹的大鼠睾丸半胱天冬酶 - 3活性略有升高。长期暴露于900兆赫兹会诱导大鼠血液中的氧化损伤并导致生殖参数改变(图4,参考文献33)。
