目的了解正常Winstar大鼠多焦视网膜电图(mERG)特点,为进一步研究打下基础。方法正常雄性Winstar大鼠10只,在同一时间段行多焦视网膜电图检查,记录其多焦视网膜电图的结果。结果正常雄性Winstar大鼠多焦视网膜电图b波的反应密度分布较稳定,各环b波波幅值有差异性,各环b波波幅值之间有一定相关性。结论稳定、可靠的记录大鼠多焦视网膜电图,有着广泛的科研应用价值。
Objective To understand the multifocal electroretinogram (mERG) characteristics of normal Winstar rats and lay the foundation for further study. Methods Ten normal male Winstar rats were examined with multifocal electroretinogram at the same time and the results of multifocal electroretinogram were recorded. Results In normal male Winstar rats, the multifocal electroretinogram of b-wave showed a relatively stable distribution of b-wave response and the amplitude of b-wave in each ring was different. There was a certain correlation between b-wave amplitude of each ring. Conclusion Stable and reliable recording of multifocal electroretinography in rats has a wide range of scientific value.
