“…Moreover, MFs increase the production of IL-1 and IL-6 by PBMC . However, in another investigation on peritoneal exudate cells, the same cytokines were not affected by MFs [Morandi et al, 1994].…”

The effect induced by exposure to 50 Hz magnetic fields (MFs) in immunocytes from the mussel Mytilus galloprovincialis is evaluated. The whole animal was exposed for 15 and 30 min to MF intensities ranging from 200 to 1,000 microT. The changes in the cellular shape of immunocytes, expressed as shape factor (SF), were studied at different times after addition of the chemotacting substance N-formyl-Meth-Leu-Phe (fMLP). Results show that MFs provoke differing delays in fMLP-induced cellular shape changes: 200 microT are ineffective, while levels from 300 microT upwards cause a significant increase in immunocyte SF values compared to controls. Reactivation of the cells is possible up to an intensity of 600 microT. The use of PCO 400, an opener of ATP-sensitive K+ channels, shows that potassium channels are involved in the effect of MFs on M. galloprovincialis immunocytes.

“…Additionally, the effect of the PEMF on the expression of IL-6 in intervertebral disc cells through the Nuclear Factor-κB and Mitogen-Activated Protein Kinase p38 pathways further underscores the potential anti-inflammatory effects of the PEMF [40]. The effects of exposure to 60 Hz on the production of IL-1 and IL-6 have been observed, highlighting possible mechanisms through which electromagnetic fields can influence immune responses [41].…”

(1) Background: This study investigated the effects of sequenced electromagnetic fields, modulated at extremely low frequencies and intensities, in the treatment of drug-resistant Escherichia coli (E. coli)-induced chronic bacterial cystitis. (2) Methods: A total of 148 female participants, aged 18 to 80 years diagnosed with chronic bacterial cystitis caused by drug-resistant E. coli, were recruited for this study. Participants were randomly assigned to two groups: an experimental group (n = 74) with osteopathic palpation and assessment treated with a sequence of electromagnetic fields, and a control group (n = 74) receiving a placebo treatment. Both groups were assessed at this study’s outset, 4 weeks after eight applications, and at 12 weeks for symptomatic presentation and laboratory parameters. (3) Results: After 4 weeks of treatment, a significant difference was observed between the two groups regarding D-DIMER levels, IL-6 levels, erythrocyte levels, leukocyte levels, and E. coli levels (p < 0.001). By the 12th week, the experimental group continued to exhibit a significant reduction in the examined parameters compared to the control group (p < 0.001). Additionally, the treatment did not induce any side effects in the patients in the experimental group. (4) Conclusions: Treatment with coherently sequenced electromagnetic fields, modulated at an extremely low frequency and intensity, not only appears to provide an effective alternative for the symptoms of chronic bacterial cystitis caused by drug-resistant E. coli but also demonstrates a potent antibacterial effect.

“…Furthermore, the latter authors reported a decrease of IL-2 receptor binding on activated human T cells under exposure to a 60 Hz, 100 T MF in the presence of a static (DC) MF [Mehta et al, 1997]. Morandi et al [1994] found no differences in IL-1 production by murine peritoneal exudate cells when exposed for 24 h to a 60 Hz, 0.3 mT MF. We recently reported that, similar to the present experiments in DMBA-treated rats, MF exposure of non-DMBA-treated female Sprague-Dawley rats for 13 weeks in a 100 T, 50 Hz MF did not alter the ex vivo production of IL-1 from PWM-stimulated splenocytes [Mevissen et al, 1998].…”
