“…Immune cells or cytokines were not modified under acute exposure to ELF magnetic fields (Selmaoui et al 1996;Selmaoui et al 2011) or GSM 900 MHz exposure (Tuschl et al 2006). In an experiment with exposure to a GSM signal, neopterin was not modified in saliva (Radon et al 2001). Other studies showed that acute exposure to ELF did not have an effect on blood concentrations of TSH, FSH, LH, testosterone, cortisol or neopterin (Gamberale et al 1989;Selmaoui et al 1996).…”

The purpose: The objective of this study was to assess the level of various salivary and urinary markers of patients with EHS and to compare them with those of the healthy control group. Materials and methods:We analyzed samples from 30 EHS individuals and a matched control group of 25 individuals (non EHS) aged between 22 and 66. We quantified cortisol both in saliva and urine, alpha amylase (sAA), immunoglobulin A and C Reactive Protein levels in saliva and neopterin in urine (uNeopterin).Results: sAA was found to be significantly higher (p < 0.005) in the EHS group. uNeopterin and sAA analysis showed a significant difference based on the duration of EHS. Conclusion:Higher level of sAA in EHS participants may suggest that the sympathetic adrenal medullar system is activated. However, most of the analyzed markers of the immune system, sympathetic activity and circadian rhythm did not vary significantly in EHS group. There is a trend to the higher levels of some variables in subgroups according to the EHS duration.

“…So far there have been remarkably few researches carried out into the effects of RF GSM radiation on melatonin secretion. In human studies, no effects of GSM radiation were found either on salivary melatonin level [Radon et al, 2001] or on blood serum melatonin concentration [Mann et al, 1998;de Seze et al, 1999]. In laboratory animal studies, neither short [Vollrath et al, 1997] nor long term [Heikkinen et al, 1999] GSM RF exposure affected melatonin or 6SM production of rodents.…”

In this study, the effect of exposure to 900 and 1800 MHz GSM-like radiofrequency radiation upon the urinary 6-sulfatoxymelatonin (6SM) excretion of adult male Wistar rats was studied. Seventy-two rats were used in six independent experiments, three of which were done with 900 MHz and the other three with 1800 MHz. The exposures were performed in a gigahertz transverse electromagnetic mode (GTEM) cell. The power densities of radiation were 100 and 20 microW/cm(2) at 900 and 1800 MHz frequency, respectively. The carrier frequency was modulated with 218 Hz, as in the GSM signal. The animals were exposed for 2 h between 8:00 AM and noon daily during the 14 day exposure period. The urine of rats was collected from 12:00 AM to 8:00 AM, collecting from exposed and control animal groups on alternate days. The urinary 6SM concentration was measured by (125)I radioimmunoassay and was referred to creatinine. The combined results of three experiments done with the same frequency were statistically analyzed. Statistically significant changes in the 6SM excretion of exposed rats (n = 18) compared to control group (n = 18) were not found either at 900 or 1800 MHz.

“…Mann et al [34] reports that in humans exposed to high frequency magnetic field, 900 Hz, pulsating at 217 Hz (the frequency of the field similar to magnetostimulation), there appears to be a slight increase in the concentration of cortisol during acute exposure, which is sustained for about an hour after the application. In a 24-hour long-term exposure, the statistically significant changes in cortisol secretion were not noted [34], just as in Kurokawa et al [35] and Randon et al [36]. Long-term M2P2 magnetostimulation influences the circadian profile of cortisol secretion by significantly…”

Objectives: The aim of this paper is to test the influence of long-term application of the low-frequency magnetic fields in magnetotherapy and magnetostimulation on cortisol secretion in men. Materials and Methods: Patients were divided into three groups: 16 men underwent magnetotherapy and 20 men (divided into two groups) underwent magnetostimulation. Magnetotherapy -2 mT induction, 40 Hz, bipolar square wave, was applied for 20 min to lumbar area. Magnetostimulation (Viofor Jaroszyk, Paluszak, Sieroń (JPS) system, M2P2 program) was applied to 10 patients for 12 min each day. The third group (10 patients) underwent magnetostimulation (Viofor JPS system, M3P3) for 12 min each day using a different machine. All groups had 15 rounds of applications at approximately 10:00 a.m. with intermissions on the weekends. Blood serum was taken four times in a 24-hour period, before applications, the day after applications and a month later. Chemiluminescence micromethod was used to indicate hormone concentrations. Data was statistically analyzed with the analysis of variance (ANOVA) method. Results: The statistically significant gains in the circadian cortisol profile at 4:00 p.m., before and after application, were observed as a decrease in concentration during magnetotherapy. In magnetostimulation, with the M2P2 program, a significant increase in the cortisol concentration was observed in circadian profile at 12:00 p.m. one month after the last application. After magnetostimulation with the M3P3 program, a significant increase in concentration at 6:00 a.m. and a decrease in concentration at 12:00 p.m. were observed one month later. Statistically significant difference was demonstrated in the participants after the application of magnetotherapy and magnetostimulation with M3P3 program compared to the men submitted to magnetostimulation, with M2P2 program, at 4:00 p.m. after 15 applications. Conclusions: Biological hysteresis one month after magnetostimulation suggests long-term influence on the hypothalamohypophysial axis. The circadian curves of cortisol secretion a day after magnetotherapy and magnetostimulation with M3P3 program compared to magnetostimulation with M2P2 progam differs nearly by 100%, which proves that they show varied influence on cortisol secretion in men. All changes in the hormone concentration did not exceed the physiological standards of cortisol secretion, which suggests a regulating influence of magnetic fields on cortisol concentration rather than a strong stressogenic impact of magnetostimulation.
