磁场对大鼠血压选择性作用的实验研究

本文观察了钕铁硼永磁体磁片产生的恒定磁场对正常大鼠、去甲肾上腺素引起血压升高的大鼠及肾性高血压模型大鼠的影响，结果表明：该磁场对正常Wistar大鼠的血压、心率均无影响；对去甲肾上腺素引起的中、轻度高血压有较好的抑制作用，且降压程度与时间、剂量呈正相关，对肾性高血压模型大鼠则没有影响，提示恒定弱磁场对大鼠血压的生物学效应取决于实验动物的机能状态。

Selective effects of magnetic fields on rat blood pressure

In the present study,the effects of constant magnetic field on blood pressure of rats from control group,nore pinephrine induced hypertensive group and renal ischemia-induced hypertensive groups were investigated.The results showed that constant magnetic fields had no effects on normal blood pressure and heart rates.It produced mild but significant inhibition on epinephrine induced mild to intermediate blood pressure elevation,yet it did not have any influence on renal ischemia-in duced hypertension.
