Electroretinography and electron microscopy were used to analyze frog retinas exposed to ultrasound. Toxic doses of ultrasound reduce the ERG b-wave amplitude and induce irreversible destructive changes in cells of all retinal layers. Therapeutic doses of ultrasound increased the b-deflection amplitude and led to slight mitochondrial edema and a decrease in the osmiophilicity of rods and cones. These studies support the view that therapeutic ultrasound doses increase the activity of photoreceptor cells.
使用视网膜电图和电子显微镜分析暴露于超声的青蛙视网膜。超声的毒性剂量会降低视网膜电图b波振幅,并在所有视网膜层的细胞中引起不可逆的破坏性变化。超声的治疗剂量会增加b波偏转幅度,并导致轻微的线粒体水肿以及视杆和视锥细胞嗜锇性降低。这些研究支持治疗性超声剂量会增加光感受器细胞活性这一观点。
