Light and electron microscopy were employed to examine ultrasonically irradiated murine neonate spinal cords. Spinal cord damage was always associated with functional changes, i.e. hind limb paralysis, and was never apparent in initially paralyzed specimens which had recovered function. Damage occurred preferentially at the periphery of the spinal cord and on the ventral side, though the ultrasound was incident on the dorsal side. The distribution of the damage suggests spinal column involvement and nonthermal effects that are enhanced by temperature elevation.
运用光学显微镜和电子显微镜检查经超声辐照的新生小鼠脊髓。脊髓损伤总是与功能变化相关，即后肢麻痹，而在已恢复功能的初始麻痹标本中从未出现明显损伤。尽管超声是从背侧入射的，但损伤优先发生在脊髓的外周和腹侧。损伤的分布表明脊柱受到累及以及温度升高会增强非热效应。
