To study the effects of the electromagnetic field emitted by cellular telephones upon the inner ear of rats, using distortion product otoacoustic emissions.
Forty Wistar Albino rats were used. Twenty newborn and 20 adult rats were divided into two groups of 10, one to participate in the study and one as a control. The rats were exposed to the electromagnetic field for 6 hours per day, for 30 consecutive days. Before and after the 30 day exposure period, distortion product otoacoustic emissions were measured in each group and a signal-to-noise ratio calculated, which was later used in statistical analysis.
For both the newborn and adult rat groups, there was no significant difference in distortion product otoacoustic emissions recorded before and after exposure to the cellular telephone electromagnetic field (p>0.05).
Exposure to the electromagnetic field emitted by cellular telephones, for 6 hours a day for 30 consecutive days, had no effect on the hearing of newborn or adult rats, at the outer ear, middle ear or cochlear level.
使用畸变产物耳声发射研究手机发出的电磁场对大鼠内耳的影响。
使用40只Wistar白化大鼠。20只新生大鼠和20只成年大鼠被分成两组,每组10只,一组参与研究,一组作为对照。大鼠每天暴露于电磁场6小时,连续30天。在30天暴露期前后,测量每组的畸变产物耳声发射并计算信噪比,随后用于统计分析。
对于新生大鼠组和成年大鼠组,暴露于手机电磁场前后记录的畸变产物耳声发射均无显著差异(p>0.05)。
连续30天每天暴露于手机发出的电磁场6小时,对外耳、中耳或耳蜗水平的新生或成年大鼠听力没有影响。
