摘要
本文研究了不同浓度的钇对发育过程中大白鼠视网膜电图(ERG)和视皮层诱发电位(VEP)的影响。用60ppm,600ppm和1500ppm的YCl_3喂养大白鼠,在刺激光强度为10LUx时,其ERG的a—b波幅度分别下降了31%、47.2%和62%,VEP的P_1波潜伏期分别延长8ms、10.2ms和12.1ms。测定了ERG的时间频率曲线随剂量的增大呈下降和变窄的趋势。
The effects of different concentration of Yurium on EGM and VEP in developing rats are studied in this paper. Rats reared with 60ppm,600ppm and 1500ppm YCl_3 show a decrease in ERG a-b wave amplitude by 31%, 47.2% and 62%, and an increase in VEP P_1 peak latency by 8ms, 10.2 ms and 12.1ms at the illuminance 10 lx,respectlvely. The treated ERGs also display a progressively lower and narrower temporal frequency curve.
