The effect of a sinusoidal 50 Hz magnetic field, 0.4 mT on regeneration of the rat sciatic nerve was studied. The sciatic nerve of intact and hypophysectomized rats was crushed and regeneration was evaluated by the pinch test and by immunocytochemical staining for neurofilaments. The animals were exposed to the magnetic field for 3-6 days, between a pair of Helmholtz coils. Hypophysectomy of the rats resulted in an impaired regeneration. However, the magnetic field exposure stimulated regeneration in both the intact and hypophysectomized animals. The results imply that the pituitary gland is not involved in magnetic field induced stimulation of nerve regeneration.
研究了0.4毫特斯拉的50赫兹正弦磁场对大鼠坐骨神经再生的影响。对完整大鼠和垂体切除大鼠的坐骨神经进行挤压，并通过捏压试验和神经丝免疫细胞化学染色评估再生情况。动物在一对亥姆霍兹线圈之间暴露于磁场3至6天。大鼠垂体切除导致再生受损。然而，磁场暴露刺激了完整动物和垂体切除动物的再生。结果表明垂体不参与磁场诱导的神经再生刺激。
