Objective: Electromagnetic shielding fabrics (EMSFs) have been marketed by several manufacturers within the past few years. However, their efficacies in protecting living organisms against the harmful effects of EM noise have yet to be established. The aim of the present study was to accomplish this task with novel in vivo experiments where fetal development and the pathological consequences of wearing protective fabric against EM radiation during pregnancy were investigated. Materials and Methods: Nine pregnant rats were equally divided into three groups. Sham controls were kept unexposed, but the remaining six were subjected to EM radiation at 900 MHz for 1 h daily throughout the pregnancy. However, three of the rats were protected by a nonwoven fabric manufactured locally and characterized previously. After birth, the kidneys of newborns were extracted and evaluated by histopathology. Histometry data were analyzed statistically. Results: EM exposure affected the kidney structure and morphology as revealed by the disruption of glomerular basement membrane continuity, increased Bowman capsule and proximal tubule sizes (from 15.01±2.56 µm to 29.94±4.42 µm), and thickened cortex and medulla (from 261.13±4.10 µm to 284.57±10.93 µm for cortex and from 594.25±23.48 µm to 732.61±20.46 µm for medulla). However, the effects were significantly attenuated in those kidneys placed behind the fabric. Conclusion: EMSF effectively protects the fetal kidney against EM radiation at 900 MHz during the developmental phase and possibly at other frequencies and for other organs. It is advisable to wear such fabrics during pregnancy when EM pollution is of significant concern.

“…No significant change was found after exposure to ELF EMFs. Some studies have reported that high-frequency EMF exposure has had some harmful effects on renal morphology and function [ 31 , 32 ]. In addition, it has been reported that exposure to ELF EMFs could cause oxidative stress in kidneys [ 33 , 34 ].…”

The aim of this study was to test whether extremely low frequency electromagnetic fields (ELF EMFs) affect health or not. Here, we constructed a 100-μT/50 Hz electromagnetic field atmosphere. A total of 128 rats were randomly assigned into two groups: the ELF EMF group and the sham group. The ELF EMF group was exposed to 100-μT/50-Hz ELF EMF for 20 h per day for three months; at the same time the other group was exposed to a sham device without ELF EMF. During the three months, the weight was recorded every 2 weeks, and the water intake and food intake of the animals were recorded weekly. The hematologic parameters were detected before and after the exposure, whereas blood chemistry analysis was performed every 4 weeks. The general condition of the exposed rats was not affected by ELF EMF. Compared with the sham group, the hematograms were not significantly altered in the ELF EMF group. Similarly, the blood chemistry (including lipid profile, blood glucose, liver function and renal function of rats) from the ELF EMF group showed no difference compared with rats from the control group during the three months exposure. The present study indicated that short-term exposure of 100-μT/50-Hz ELF EMF may not affect hematograms and blood chemistry in rats.

Mercury in the environment that arises from organic and inorganic sources can cause irreversible damage to the nervous system. Toxicity may be direct or may arise from interactions with other metals in the environment. We evaluated the possible effects of mercury vapor on rat cerebellum. Twelve adult female rats were divided into control and experimental groups. The rats in the experimental group were exposed to mercury vapor for 9 h/day for 45 days. Cerebellar tissue samples were evaluated using stereology and for histopathology. The total number of Purkinje cells was estimated using a physical disector method. We found that in the experimental group, overall volume decreased and the number of Purkinje cells was reduced. We also found cellular damage including pycnotic nuclei, eosinophilic cytoplasm and vacuolization; these features were absent in the control group. We found that chronic exposure to inorganic mercury vapor is toxic to the cerebellum.

Effects of prenatal 900 MHz electromagnetic field exposures on the histology of rat kidney

Abstract: Prenatal exposure of rat kidneys to 900 MHz EMF resulted in increased total kidney volume and decreased the numbers of glomeruli. Moreover, MEL and ω-3 prevented adverse effects of EMF on the kidneys.
