Abstract

Abstract Background: Although the scientific community is extensively concerned with the effects of the EMF, the unambiguous explanation of its effects on living structures is still lacking. Goals: The goal of the study was to evaluate the effect of a low-frequency (LF) electromagnetic field (EMF) on the growth and multiplication of the yeast Saccharomyces cerevisiae. Methods: Yeast cells were exposed to a frequency of 900 Hz and a magnetic flux density of 2.3 mT. The duration of each experiment was 8 hours, in the beginning of the measurement the value of frequency, rms (root mean square) value of electric current (2 A), and magnetic flux density were fixed set on the exposure device. A paired experiment was performed, a sample exposed to EMF, and a sample shielded from the field. Subsequently, samples were taken every two hours, the number of cells was recorded, and then the concentration of the yeast cells was evaluated at time points. The time points reflected the exposure time of the samples exposed to EMF. Results: The results indicate that LF EMF at given parameters has an inhibitory effect on the growth and multiplication of yeast cells. Conclusion: Exposure to EMF can cause the differences in growth dynamics between cells exposed to the field and the unexposed ones.

低频电磁场对酿酒酵母属酵母细胞的生物学效应

摘要背景：尽管科学界广泛关注EMF的影响，但对其对生活结构的影响仍缺乏明确的解释。目的：本研究的目的是评估低频（LF）电磁场（EMF）对酿酒酵母生长和增殖的影响。方法：将酵母细胞暴露于900Hz的频率和2.3mT的磁通密度下。每个实验的持续时间为8小时，在测量开始时，将频率值、电流（2A）的均方根值和磁通密度固定在暴露装置上。进行配对实验，将样品暴露于EMF，并将样品屏蔽在磁场之外。随后，每两小时取样一次，记录细胞数量，然后在各时间点评估酵母细胞的浓度。时间点反映了暴露于EMF的样品的暴露时间。结果：在一定参数下，低频电磁场对酵母细胞的生长和增殖有抑制作用。结论：暴露于电磁场可导致暴露于电磁场和未暴露于电磁场的细胞之间的生长动力学差异。

期刊介绍： Acta Medica Martiniana is a medical scientific journal, first published in print form in December 2001. It is a continuation of the journal / almanac Folia Medica Martiniana (1971 - 1996). The journal‘s owner is the Jessenius Faculty of Medicine, Comenius University, Slovakia. Dissemination of research results and scientific knowledge from all areas of medicine and nursing. Stimulation, facilitation and supporting of publication activity for the young medical research and clinical generation. The contributions of young novice authors (PhD students and post-doctorials) are particularly welcome. Acta Medica Martiniana is an open-access journal, with a periodicity of publishing three times per year (Apr/Aug/Dec). It covers a wide range of basic medical disciplines, such as anatomy, histology, biochemistry, human physiology, pharmacology, etc., as well as all clinical areas incl. preventive medicine, public health and nursing. Interdisciplinary and multidisciplinary manuscripts, including papers from all areas of biomedical research, are welcome.
