Abstract

A general theory explaining how electromagnetic waves affect cells and biological systems has not been completely accepted yet; nevertheless, extremely low-frequency electromagnetic fields (ELF-EMFs) can interfere with and modify several molecular cellular processes. The therapeutic effect of EMFs has been investigated in several clinical conditions with promising results: in this context a better understanding of mechanisms by which ELF-EMF influences cellular events is necessary and it could lead to more extended and specific clinical applications in different pathological conditions. This paper develops a thermodynamic model to explain how ELF-EMF directly interferes with the cellular membrane, inducing a biological response related to a cellular energy conversion and modification of flows across cell membranes. Indeed, energy, irreversibly consumed by cellular metabolism, is converted into entropy variation. The proposed thermodynamic model views living systems as adaptative open systems, analysing the changes in energy and matter moving in and out of the cell.

低能量电磁场与生物系统之间的生物物理相互作用的热力学考虑。

解释电磁波如何影响细胞和生物系统的一般理论尚未被完全接受；然而，极低频电磁场（ELF-EMFs）可以干扰和改变多种细胞分子过程。电磁场的治疗效果已在几种临床病症中进行了研究，并取得了令人鼓舞的结果：在这种情况下，有必要更好地了解 ELF-EMF 对细胞事件的影响机制，这可能会导致在不同病症中更广泛、更具体的临床应用。本文建立了一个热力学模型，以解释 ELF-EMF 如何直接干扰细胞膜，诱发与细胞能量转换和改变细胞膜流动有关的生物反应。事实上，细胞新陈代谢不可逆转地消耗的能量会转化为熵变。所提出的热力学模型将生命系统视为适应性开放系统，分析进出细胞的能量和物质的变化。
