临床实践表明,周围神经损伤后虽能再生,但再生和功能恢复的速度过慢。多年来医学家们着重研究促进神经再生的营养因素,而对体内存在有害于神经再生的因素未能予以足够注意。本研究系从后一观点出发,以兔坐骨神经挤压损伤为模型,通过光、电镜观察以及对前列腺素(PG)F_(2a)的 Clinical practice shows that although the regeneration of peripheral nerve injury, but regeneration and functional recovery too slowly. For many years, medical scientists have focused on the nutritional factors that promote nerve regeneration, but failed to pay enough attention to the factors that have harmful effects on nerve regeneration in the body. In this study, from the latter point of view, the sciatic nerve crush injury in rabbits as a model, through light and electron microscopy as well as prostaglandin (PG) F_ (2a)
