Studies on Genotoxic Effects of Mobile Phone Radiation on A375 Cells

Introduction: Radiation from cell phones has been associated with an increased risk of cancer. The literature has reported evidence of certain biological effects resulting from exposure to various wavelengths, doses, and intensities of radiofrequency radiation. The present study aimed to evaluate the possible adverse effects of radiation from a GSM mobile phone operating at 900 MHz on human melanoma A375 cells. Material and Methods: Cellular morphology was observed under an inverted phase contrast microscope. Cell viability was determined through trypan blue dye exclusion and clonogenic assay. Moreover, flow cytometry was applied to detect DNA damage, cell cycle arrest, and reactive oxygen species (ROS) production. Cellular reduced glutathione (GSH) content was estimated by measuring the total soluble thiol. In addition, the physico-chemical changes were assessed using spectrophotometer and viscometer. Results: This study revealed that there was no change in cellular morphology and necrotic cell killing; although a small effect was observed on delayed cell death. Depletion in GSH content was noted, but ROS generation was not significantly different from that of the control group. No DNA damage was found during such exposure and there was no alteration in cell cycle distribution. In vitro evaluation of radiation effect on calf thymus DNA showed a slight perturbation in absorption spectra that was completely reversible with time. On the other hand, viscometric analysis showed no changes. Conclusion: From the findings, it can be concluded that this range of mobile phone radiation for 60 min of continuous exposure has no genotoxic impact on A375 cells.

AB037. Long-term exposure to the mobile phone radiation decreased the sperm quality of Sprague Dawley rats

BackgroundTo investigate the long-term effect of mobile phone radiation on the sperm quality of male Sprague Dawley (SD) rats.MethodsMobile phones (Nokia, 1.58 W/kg, 4G mobile network) were applied to emit the radiofrequency electromagnetic radiation. And rats were exposed to the mobile phone radiation for 150 days, 4 hours/day. During the modeling process, the mobile phone was in an active call and received an extra call every 10 minutes. Epididymis sperm quality analysis, mating experiment, hematoxylin-eosin staining, reactive oxygen species analysis and western blot were performed to comprehensively assess the effect of mobile phone radiation on the sperm quality and testis of rats.ResultsThe sperm concentration, sperm motility and sperm viability were significantly downregulated, and the abnormal sperm rate and sperm DNA fragmentation index were upregulated in the rats exposing to the mobile phone radiation for 150 days. The mating experiment showed that the cub weight of rats decreased after exposing to the mobile phone radiation for 150 days. The testicular malondialdehyde (MDA) and 4-Hydroxynonenal (HNE) level were upregulated whereas the superoxide dismutase (SOD), catalase (CAT) and glutathione (GSH) level were downregulated in rats exposing to the mobile phone radiation for 150 days. In addition, the protein level of Fas, FasL and the rate of cleaved-caspase-3 to pro-caspase-3 were upregulated in the testis of these rats. The hematoxylin and eosin (H&E) staining showed that the spermatogenesis was disturbed in rats exposing to the mobile phone radiation for 150 days. However, the sperm quality and spermatogenesis of rats did not significantly change after exposing to the mobile phone radiation for 100 or 50 days.ConclusionsLong-term exposure to the mobile phone radiation decreased the sperm quality of rats, which might attribute to disturbing the spermatogenesis.

Effects of mobile phone prolonged radiation on kidney cells; an in-vitro study

Introduction: Mobile phones have been shown to have hazardous effects on the human renal system, reproduction and development, central nervous system and immune function. Objectives: This study aimed to investigate whether the mobile phone prolonged radiofrequency (RF) radiation could affect healthy kidney cells in an in-vitro study. Materials and Methods: Human kidney healthy cells in three groups were placed into three batches. The first and second groups (exposed groups) were exposed to a mobile phone simulator for 1 and 2 h/d, respectively. The irradiation was performed for 8 consecutive days. For the third group (control group), no radiation was applied to the samples and they completed the assay cycle under identical conditions. Cells’ survival was evaluated using MTT [3-(4,5-dimethylthiazol–2- yl)-2,5-diphenyltetrazolium bromide] assay. Statistical significance of the differences between control and exposed groups were assessed using the repeated measure ANOVA method (P<0.05). Results: Results showed that radiation exposure from mobile phones simulator decreased the kidney cell survival in the exposed groups (up to 40%). ANOVA test revealed that a significant decrease in cell survival in the exposed group compared to the control group (P=0.014). No significant differences between the irradiated groups were found (P>0.05). Conclusion: Mobile phone exposure affects kidney cells survival during an in vitro condition. To study the effects of mobile phone radiation on kidney, further in vivo studies on mammalians are needed.

Effects of mobile phone radiation and exercise on testicular function in male Wistar rats

Background: The aim of this study was to investigate the effects of mobile phone radiation and exercise on testicular function in male Wistar rats. Methods: Twenty male Wistar rats weighing 150–198 g were used for this experiment. The animals were divided into four groups (n = 5). The first group was the control group, the second group was exposed to mobile phone radiation for 6 h daily, the third group was subjected to swimming >three times a week and >30 min each session or >90 min a week, and the fourth group containing five rats was exposed to mobile phone radiation for 6 h daily and was subjected to swimming for >three times a week and >30 min each session or >90 min a week. This experiment lasted for 30 days. A Nokia 1280 cell phone was used to emit electromagnetic waves, and the cages of Groups 2 and 4 were surrounded by aluminum foils to focus and limit the waves to the interior of the cages, with the phone being placed 0.5 cm under the cage. A radiofrequency radiometer was kept close to the cages to detect the cell phone radiation. Results: Short-term exposure of male Wistar rats to mobile phone radiation (6 h/day × 30 days at 1.6 W/kg specific absorption rate) led to a statistically insignificant (P > 0.05) decrease in the serum testosterone levels and testicular weight, whereas exercise (> three times a week and >30 min each session or > 90 min a week) in male Wistar rats led to statistically nonsignificant (P > 0.05) increase in the testosterone levels and testicular weight. Conclusions: The findings of this study indicated that short-term exposure of mobile phone radiation leads to a statistically nonsignificant decrease in serum testosterone levels and testicular weight, whereas regular exercise leads to a statistically nonsignificant increase in the testosterone levels and testicular weight.

Radiation Effects of Mobile Phones and Tablets on the Skin: A Systematic Review.

Background Skin health has become a worldwide concern. Most of the studies investigated the effect of mobile phone radiation on DNA and animals, but a few studies were carried out about skin diseases in mobile phone and tablet users. Few systematic studies have examined the relationship between mobile phone exposure and skin diseases. Methods We evaluated the association between mobile phones and tablets and skin diseases. We checked databases including PubMed, Scopus, Springer, Cochrane, and Google Scholar from 1995 to 2013. The eligibility criteria were descriptive, and observational studies were in English and Persian language, and the subjects were of all ages and reported skin disease. Results Most of the studies focused on signs and less on skin cancer. In total, 6 studies were included with 392119 participants with age over 25 years. In a nationwide cohort study in Denmark for BCC, the IRR (incidence rate ratios) estimates remained near unity among men and women. In the other studies, they reported an increase in temperature, hypersensitivity of warmth, facial dermatitis, angiosarcoma of the scalp, and burning sensations in the facial skin after mobile phone use on the exposed side and more within the auricle and behind/around the ear. Conclusions Overall evaluations showed that the level of evidence associated with the effects of radiation from the mobile phone and tablet on the skin is poor. This review shows a necessity for more studies in this area.

The Effects of Acute Mobile Phone Radiation on the Anxiety Level of Male Rats

Objectives: Despite two decades of using mobile phone, the biological effects of electromagnetic radiation remain controversial. The study was conducted to determine the effect of mobile phone waves on anxiety-like behaviors in male rats. Methods: A total number of 80 male naive rats were, randomly, divided into eight groups (Control, 900, 1 800, and 2 100 MHz exposure). The acute and chronic effects of mobile phone radiation on the anxiety profile was compared considering a 45-min session and seven sessions of radiation (45 min/day) using the elevated plus-maze (EPM) in rats. The number of rats entering the open and closed arms and their duration of stay in each of the arms were assessed. To estimate the oxidative stress, Superoxide Dismutase level in the blood serum was evaluated. Results: The results obtained in the EPM showed no significant differences among the groups after acute exposure to mobile phone radiation (P > 0.05). No significant differences were observed among the groups in terms of their serum superoxide dismutase level (P > 0.05). Conclusions: Short time mobile phone radiation had no effect on anxiety-like behaviors and serum enzyme activity; this may be due to low tissue irritation during acute exposure to mobile phone waves.

Immediate effects of mobile phone radiations on heart rate variability in college going students

Background: The use of mobile phone has increased excessively these days which can have a deleterious effect on human tissues and organs, especially cardiovascular system (CVS). The effects on CVS can be detected at an early stage by analyzing alterations in heart rate variability (HRV). Aims and Objectives: This study was designed to determine the effect of mobile phone use with different components of HRV. Materials and Methods: In our study, HRV was measured in 95 college-going students (males: 49 and females: 46) using root mean square polyrite-D during 3 phases with each phase being recorded continuously for 2 min: Phase 1: Basal recording; Phase 2: Mobile phone use during active call with direct contact to the ear; and Phase 3: Mobile phone use during active call with earphones. Data obtained were subjected to statistical analysis using repeated measures non-parametric test followed by multiple comparison tests. Results: There was a significant increase in mean HR and decrease in mean RR interval from baseline through Phase 3 to Phase 2. This study shows that there was statistically significant change in root of the mean of the sum of the squares of differences, low frequency (LF), high frequency (HF), and LF/HF ratio between basal recording and during active call (direct contact of mobile phone to the ear and also with use of earphones); however, no change was seen between direct contact of mobile phone to the ear and during the use of earphones. Standard deviation of all normal-to-normal intervals did not show any significant change. We also observed gender differences in some of the HRV parameters. Conclusion: There is a considerable effect of mobile phone use on HR and HRV parameters. Furthermore, the changes noted are less with earphone use than when compared with the use of mobile phone in direct contact with the ear though these differences were not significant statistically.

Acute effects of mobile phone radiations on subtle energy levels of teenagers using electrophotonic imaging technique: A randomized controlled study.

Background:Mobile phones induce radio frequency electromagnetic field (RF-EMF) which has been found to affect subtle energy levels of adults through Electrophotonic Imaging (EPI) technique in a previous pilot study.Materials and Methods:We enrolled 61 healthy right-handed healthy teenagers (22 males and 39 females) in the age range of 17.40 ± 0.24 years from educational institutes in Bengaluru. Subjects were randomly divided into two groups: (1) (mobile phone in ON mode [MPON] at right ear) and (2) mobile phone in OFF mode (MPOF). Subtle energy levels of various organs of the subjects were measured using gas discharge visualization Camera Pro device, in double-blind conditions, at two points of time: (1) baseline and (2) after 15 min of MPON/MPOF exposure. As the data were found normally distributed, paired and independent samples t-test were applied to perform within and between group comparisons, respectively.Results:The subtle energy levels were significantly reduced after RF-EMF exposure in MPON group as compared to MPOF group for following areas: (a) Pancreas (P = 0.001), (b) thyroid gland (P = 0.002), (c) cerebral cortex (P < 0.01), (d) cerebral vessels (P < 0.05), (e) hypophysis (P = 0.013), (f) left ear and left eye (P < 0.01), (g) liver (P < 0.05), (h) right kidney (P < 0.05), (i) spleen (P < 0.04), and (j) immune system (P < 0.02).Conclusion:Fifteen minutes of RF-EMF exposure exerted quantifiable effects on subtle energy levels of endocrine glands, nervous system, liver, kidney, spleen, and immune system of healthy teenagers. Future studies should try to correlate these findings with respective biochemical markers and standard radio-imaging techniques.
