多年来,已经报道了用施加的电场成功治疗各种医疗投诉。受这种治疗影响并促进积极作用的细胞机制的身份仍然难以捉摸。对许多体外和体内报告的研究表明,有益的效果可归因于膜蛋白的活化,特别是参与信号转导机制的蛋白。不仅蛋白质可能受到影响,而且现在已经确定,在电刺激细胞后观察到的增强的Ca(2+)内流也有助于许多钙依赖性细胞过程,这可能与本文讨论的治疗效果有关。提出了一种由低至中等频率(低于150 Hz)的较小(10(3)~ 10(4)V m(-1)范围)电场引起的物理变化的假设。
Successful treatment of various medical complaints with an applied electric field has been reported over the years. The identities of the cellular mechanisms that are influenced by this type of treatment and facilitate the positive effects, remain elusive. A study of many in vitro and in vivo reports revealed that the beneficial effects can be attributed to the activation of membrane proteins, and specifically proteins involved in signal-transduction mechanisms. Not only may the proteins be affected but it is now well established that enhanced Ca(2+)influx, observed to follow electric stimulation of cells, also contributes to many calcium-dependent cellular processes which can be linked to the therapeutic effects discussed in this paper. An hypothesis of the physical changes caused by an applied, relatively small (10(3)to 10(4)V m(-1)range), electric field with low to moderate frequency (below 150 Hz), is postulated.
