“…Also, in harmony with about hematological parameters (Eid et al 2015). The depletion in the values of hematological parameters following EMF radiation may be attributed to direct deterioration caused by radiation and overproduction of ROS by microwave radiation interaction, causing hemolysis (Aweda et al 2004). The dwindling of RBCs may be due to the interaction between heme (iron) and SMF, where the magnetic eld penetrates the body and acts ions in all organs, altering the cell membrane's potential disrupting the ions (Kula and Drozds 1996).…”

“…Increasing ROS generation can lead to calcium homeostasis disorders, increased membrane uidity, and cell death(Hassanen 2015). Table(5) shows no presumed divergences between R.o cinalisextract remedy groups compared to standard control in CAT and MDA vigor after 30days.Meanwhile, HV sensitivity increased by approximately 36.8 % (p > 0.05) and 42.4 % (p > 0.05) respectively, while CAT vigor increased by approximately 20.2 % and 30.4 % relative to the control group ( p > 0.05). However, the MDA scale showed a suspected diminishing (p > 0.05) in handling with R.o cinalis extract simultaneously as 2 or 4 h exposure to HV.…”

Electromagnetic fields (EMFs) are common in our everyday lives. They have many origins and severe effects on individuals and environments where they inflict a great deal of health and psychological harm. The current study investigated the impact of high voltage (H.V.) EMF 5.4 k / v for 2, 4 h per day with a frequency equal to 50 Hz on body weight(b.wt), blood indices, and certain liver enzymes of albino rats after 25 days of exposure to the electromagnetic field. This work focuses on the therapeutic action of methanol extract of Rosmarinus officinalis (R. officinalis) leaves at a dose (5 mg/kg b. wt) against harmful EMF-induced effects. The findings showed that electromagnetic field exposure induced a substantial decrease in red blood cells (RBC), haemoglobin concentration (Hb), and catalase activity (CAT). Although white blood cells (WBCs), aspartate aminotransferase (AST), alanine aminotransferase (ALT), Total Bilirubin, Urea, Creatinine, Uric Acid, and Malondialdehyde (MDA) levels have increased significantly under EMF treatment. Treatment with R.officinalis showed attenuation in these parameters that were induced in rats exposed to H.V. These findings were followed by the histopathological analysis of the liver in the observations. Finally, we conclude that R.officinalis leaves extract offered substantial protection against H.V induced liver damage and can be applied in drug production.

Background: The use of mobile phones, wireless, and electrical devices has gradually increased throughout the last century, and scientists have suggested that electromagnetic fields (EMFs) generated by such devices may have harmful effects on living creatures. Many studies revealed that the EMFs might produce a variety of adverse effects on human health as headaches, chronic fatigue, heart problems, stress, nausea, chest pain, and also some bad effects on central nervous, endocrine and immune systems. Exposure to EMF result in deterioration of RBCs function and metabolic activity, it was expected that, the increase of toxicity in specific organs was a result of the RBCs functional failure. The mechanisms by which the electromagnetic fields cause their bad effects may be by causing deterioration in cellular large molecules, imbalance in ionic equilibrium and generation of reactive oxygen species (ROS). These reactive oxygen species can damage cellular components such as proteins, lipids and DNA. Measurements of blood parameters are of the most important diagnostic methods by which we can determine the health status of human and animals for certain diseases as anemia, leukemia and also detect the presence of the inflammations.Objectives: This study aimed to present an overview on the previous works from 1997 to 2018 on the varying effects of electromagnetic fields on haematological data in human and different species of experimental models by using different frequencies, intensities, and different sources of electromagnetic fields for different periods. The hematological parameters are fluctuating across the exposure period to the EMFs suggesting the possible induction of hazardous biological effects during the exposure to magnetic field. Conclusion:It can be concluded that exposure of human and experimental animals to EMFs cause harmful effects on blood cells. These effects were disturbance in haematological parameters depending on species, the sources of EMFs, frequencies, intensities and duration of exposure.

“…The distance setting range is also wide, so even if the target moves, it does not matter where it is within the line gain range. However, the target must be stationary at the moment of measurement [14][15][16][17][18]. To increase spatial resolution, increase the frequency.…”

We report the development of a non-contact monitoring device for avian cardiac output and breathing patterns based on the anterior thoracic air sac pressure that uses transmission-type microwaves (2,400−2,500 MHz, continuous wave). Since the phase waveform represents the dielectric constant change, the phase reflects −j/ωc and the dielectric constant change is related to blood flow. The magnitude waveform is reflected from the electronic resistance of tissues due to the expansion of the anterior thoracic air sac, which mainly consists of the thoracic wall. To confirm these waveforms, pigeons and chickens were used for testing. To validate the output waveforms of the developed transmission-type microwave device, data from esophageal catheters and pressure sensors in the anterior thoracic air sac, abdominal air sac, and intraoral cavity were obtained. The waveform for the esophageal catheter, where electrocardiogram electrodes and an angular velocity sensor were installed, correlates with cardiac output. A heart sound microphone was used to confirm the closing sound of the arterial and mitral valves. The experimental results confirm that a linear waveform synchronized with the cardiac blood flow and the anterior thoracic air sac pressure of birds was obtained using transmission-type microwaves. The proposed device, which can monitor cardiac output and respiratory patterns, may enable the early screening of cytokine storms caused by avian influenza viruses. Existing devices use Doppler radar in the 10 to 77 GHz band; these high frequencies are reflected by the chest wall and do not reach deep into body, making it impossible to monitor the blood flow inside the body.
