静磁场暴露对于大鼠睾丸组织电学特性的影响

目的研究静磁场暴露对于大鼠睾丸组织介电特性与导电特性的影响,从细胞水平和分子水平分析静磁场对于大鼠睾丸组织的影响。方法在10 kHz～10 MHz范围内测量被1700 Gs静磁场暴露作用大鼠的睾丸组织的电容和电阻,并进一步通过测试结果计算其介电与导电特性。结果通过静磁场暴露作用的大鼠其睾丸组织的介电常数总体上呈现降低趋势,在第7天以后开始恢复,在频率较高时恢复的时间较早,其电导率的变化趋势则是先上升,在第5天以后开始下降,具有显著差异的结果主要集中在较低频率的10 kHz～100 kHz范围内。结论静磁场对于大鼠睾丸组织电学特性的显著的影响主要集中在细胞水平,对于分子水平的影响不显著,并且这些影响在一段时间后可以自行恢复。

Effects of Static Magnetic Field Exposure on Electrical Properties of Testis in Rats

Objective To study dielectric properties and conductive characteristics of testis in rats exposed to the static magnetic field,and to analyze the bioeffects of static magnetic field on the cellular and molecular level.Methods Capacitance and resistance of testis in rats exposed to 1700Gs static magnetic field were measured within 10 kHz~10 MHz range,and the dielectric and conductive properties were further calculated.Results The dielectric constant of rat testis decreased in general after static magnetic field exposure and began to recover on the seventh day.The recovery is earlier for the higher frequencies.Earlier trend of the conductivity is increase,and begin to decline after the fifth day.All these results with a significant difference mainly concentrated in the lower frequency range(10 kHz~100 kHz).Conclusion Effects of static magnetic field on the electrical properties of rat testis are mainly at the cellular level,the molecular level was not significant,and these effects can be self-healing over time.
