“…[20] Adult male Wistar rats were exposed to static magnetic field (128mT) for 1h./5 days/week for 6 weeks showed significant increase of platelet count (+10%, p<0.05) compared to control group. [21]. The immediate effects of whole body exposure to 2.450 GHz magnetic radiation on hematological parameters on 140 adult Wistar rats showed Platelet count reduced from the control value immediately after exposure then increased gradually after 1, 2, 4 and 8 weeks respectively [22].…”

Background: Magnetic field is now recognized by the 21 st century medicine as real physical entities that promise the healing of various health problems. In the last few decades, various studies refer to biological effect of magnetic field exposure have been in progress. Most of studies carried out on mice, rat and little on human showed that magnetic fields induced changes in hematological parameters in these organisms. Purpose: To assess the effect of pulsed magnetic field on platelets count and coagulation process in healthy subjects. Methods: Thirty-one participants divided into two groups, a study group (A) (23 subjects), and a control group (B) (8 subjects). Their ages ranged from 25-40 years. They were selected from the staff members working at the police authority hospital El-Agouza. They were free from any health problems and not previously treated by magnetic field. Group (A) received magnetic field for 12 sessions successively over one month by the rate of 3 sessions per week, with low frequency (10 HZ), low intensity (10 G) and for 20 minutes, While Group (B) didn't be exposed to magnetic field just placement in the device as a placebo. The subjects were evaluated pre and post exposure for both platelet count and INR. Results: showed that group A that received pulsed magnetic field had significant increase of platelets count and significant reduction of INR, while the other group had no significant difference in both oh them. Conclusion: Pulsed magnetic field increases platelets count and decreases coagulation.

“…Regular exposure to electromagnetic field can increase plasma volume with a consequent decrease in the concentration of Hb and RBCS in blood as stated previously 16 . The decrease in the concentration of hemoglobin could be attributed to the interaction between iron of haeme and electromagnetic field, by which magnetic field enters the body and acts on ions in all the vital organs such as spleen, bone marrow, kidney and liver, it alters the cell membrane potential and distribution of ions 17 .…”

Objectives: Radiofrequency of mobile phones may affect biological systems by increasing free radicals and by changing the antioxidant defense systems of tissues, thus leading to oxidative stress. L-cysteine, as a glutathione precursor, has an antioxidant property that may prevent oxidative damage to normal cellular processes. Methods: The effect of different concentrations of parentral L-CyS-HCl against harmful effects of EMR on rats' blood was studied namely: hematological parameters (osmotic fragility and blood picture), and biochemical parameters (reduced glutathione and malondialdehyde levels). Results: The results revealed that 20 mg parenteral L-CyS-HCl showed high protection for EMR radiated rats against hemolysis. In addition, EMR radiated rats received 20 mg parenteral L-CyS-HCl showed normal blood picture, GSH and Malondialdehyde levels, compared to radiated untreated rats. Conclusion: Parenteral L-CyS-HCl can be used for protection against mobile phone hazards

“…It has been reported that SMF (including moderate fields) can be responsible for vascular responses in vivo. Effects can be observed in vascular and blood system components such as ion channels on the smooth muscle of the vascular wall [Gmitrov et al, ], platelet number [Amara et al, ], blood flow [McKay et al, ], and pressure [Okano and Ohkubo, ]. It is plausible that the SMF effects found here might be extended to therapeutic methods of thrombus dissolution.…”

The influence of a static magnetic field (SMF) on crude enzyme extracts with proteolytic activity is described and discussed. Proteolytic enzymes, which hydrolyze peptide bonds, and fibrinolytic enzymes, which dissolve fibrin clots, have industrial relevance, and applicability dependent on improvements of productivity and activity. We investigated whether a moderate SMF affects proteolysis in different in vitro tests: general proteolysis of azocasein substrate, and static and dynamic fibrinolytic processes (to compare fibrin gel configuration under exposure). Crude enzyme extracts, obtained from solid state fermentation of Mucor subtilissimus UCP (Universidade Católica de Pernambuco, Recife, Brazil) 1262, were used to carry out assays under slightly heterogeneous fields: a varied vertical SMF (for tests in Eppendorf tubes, from 0.100 to 0.170 T) and a varied horizontal SMF (for tests in Petri dishes, from 0.01 to 0.122 T), generated by two permanent magnets (NdFeB alloy). Results showed significant differences (P < 0.05) in static fibrinolysis assays after 24 h of exposure. The mean diameter of halos of fibrin degradation in the treated group increased by 21% compared to the control group; and the pixel number count of fibrin consumption (in a computational analysis of the area of each halo) enhanced by 30% with exposure. However, in dynamic fibrinolysis assays, no effects of SMF were observed. These results suggest a response of fibrin monomers to the SMF as a possible cause of the observed effects.
