Effect of electromagnetic field on whole blood, biochemical and hormone level in human

The electromagnetic field is increasing in our environment and these exposures cause concern. The aim of our study is to investigate the effects of magnetic fields generated by the hairdryer devices used by women working in the same job on their serum biochemistry, whole blood, and hormone values. The sixteen women working continuously in hairdressing salons were included in the study. Two groups of studies were designed: control (n:8, mean age: 22.25±6.04) and experimental group (n:8, mean age:23,62±6.67). The biochemical (median values of alanine aminotransferase, aspartate aminotransferase, triglycerides, and very-low-density lipoprotein were found high) and hormonal results of the experimental group were compared with the biochemical (cholesterol, low-density lipoprotein, and very high-density lipoprotein had high median values) and hormonal results of the control group and no significant difference was found (p>0.05). When the whole blood parameters were examined, the white blood cells and mean platelet volume results of the experimental group were significant (p<0.05), while there was a meaningless difference between red blood cell, hemoglobin, hematocrit, mean corpuscular volume, red cell distribution width and platelet values (p>0.05). It is evident from the results that occupational exposure to magnetic fields constantly leads to changes in the biochemistry, hormone and whole blood parameters of the female

Possible Effect of 2100 Mhz Cell Phone Radiation on Heart and Spleen Tissues of Rats- 2100 Mhz Cep Telefonu Radyasyonun Sıçan Kalp ve Dalak Dokularına olası Etkileri

Introduction:The widespread access of the society to mobile phones and their intensive use cause health concerns. This study is aimed to investigate the possible histopathological effects of exposure to Radio-frequency Radiation (RFR) originating from mobile phones rat heart and spleen tissue.Methods: Totally 14 Sprague Dawley male rats were used and divided into 2 group (n= 7 for each); sham-control group, exposure group. RFR exposure group was exposed to 2100 MHz GSM-like RFR for 5 hours/day, for 14 days. Heart and spleen tissues of all rats were sampled for histopathological examination and hematoxylin-eosin staining was performed. For p53 examination, immunohistochemical staining was also used in both tissues.Results: Histopathological and immunohistochemical evaluation revealed no significant changes in heart tissue, but trabecular irregularity and enlargement of sinusoids were observed in the spleen in histopathological evaluation.Conclusion: It was observed that short-term RFR exposure did not cause significant morphological changes in heart and spleen tissue. This situation may be seen due to the protective effect of the body against RFR

The effect of short-term electromagnetic fields caused by mobile phones on the electrical activity of alpha and beta brain waves

Aim: The widespread use of mobile phones by people is increasing in society. The effect of these areas on neurophysiological and EEG is intriguing. In this study, we aimed to investigate the effect of short-term cell phone-induced electromagnetic field on the electrical activity of the EEG alpha and beta bands in the human brain.Materials and Methods: The study was carried on twenty males divided into four groups such as Group 1: eyes closed (10 sec), Group 2: eyes open (10 sec), Group 3: phone exposure (3 min) and Group 4: control group (no phone, 3 min).Results: In our study, no significant change was observed in the EEG electrical activity of the alpha waves between mobile phone use and non-use (p>0.05). As a result of the analysis made for the beta waves, in the comparison between the group exposed to the mobile phone and the non-exposed group, there was a significant difference between the FFT max F and PSD max power parameters (p0.05).Discussion: The use of mobile phones can lead to some changes in the electrical activity of some bands of the brain

The protective effect of melatonin and Ganoderma lucidum against the negative effects of extremely low frequency electric and magnetic fields on pulp structure in rat teeth

Background/aim: The aim of this study was to determine whether Extremely low frequency electric and magnetic field (ELF-EMF) had any harmful effects on dental pulp tissue and examine histologically whether melatonin (MLT) and Ganoderma lucidum (GL) play a protective role against these harmful effects. Material and method: A total of 56 adult, male Wistar Albino rats were used in the study. The rats were separated into 8 equal groups and were exposed to ELF-EMF, generated by high voltage source, for 8 hours/day for 26 days – Groups I, II and III and for 52 days-Groups V, VI and VII. For sham-control groups (Groups IV and VIII for 26 and 52 days), rats were placed into same experimental set-up as exposure groups and same procedure was applied except ELF-EMF exposure. GL (20 mg/kg/day) and MLT (10 mg/kg/day) were administered by oral gavage and the intraperitoneal route respectively. At the end of the study, the rats anterior teeth were examined immunohistochemicaly using vimentin and vascular endothelial growth factor (VEGF). Results: Degeneration in the odontoblast cells, inflammatory cell infiltration, dilatation of the blood vessels and haemorrhagic changes were determined in the pulp of the rats in Groups I and V. A statistically significant difference was determined in the groups treated with MLT and GL (p < 0.05). Conclusion: It was determined that exposure to ELF-EMF induced histological changes in the dental pulp of rats, the using of MLT and GL could have a protective effect against these effects

Yüksek Gerilim Hattı İle Oluşturulan Elektromanyetik Alanın, Rat Spermatogonium Hücreleri Üzerindeki Etkisinin Belirlenmesi

Objective: Purpose of the study was to research the effect of an electromagnetic field created by a high voltage line onthe testes tissue and the serum biochemistry of Wistar albino male rats. At the same time, in the study also examinedthe protective effects of melatonin and ganoderma lucidum.Methods: In the study, 64 rats were divided into eight equal groups (n: 8). In experiments lasting 26 and 52 days, thefollowing groups were used: High voltage (HV), HV Ganoderma lucidum (GI), HV Melatonin (MEL), and Shamcontrol.MEL (10 mg/kg) was administered intraperitoneally and GI (20 mg/kg) as oral lavage. Extremely lowfrequency electric (80.3 V/m) and magnetic fields (2.48 µT) were applied for eight hours per day. Results: The biochemical results of the study show an increase in total oxidant status (TOS) and oxidative stress index(OSI) level and a decrease in total antioxidant status (TAS) level in the 26 and 52 day high voltage groups, comparedto the control group. In the high voltage groups, the nitric oxide (NO) value increased with the increase of theexposure period. Testicular mass (p0.05), TAS, TOS, OSI and NO (p0.05) were found at 26 days of comparison.Testicular weight, TAS, TOS, OSI (p0.05), and NO (p0.05) were found in 52 day comparisons. In routinehistopathology data, we detected effects on both the 26 and 52 day HV groups, such as degeneration in spermatic cellsand full structural deterioration and increasing hyalinisation. We also detected an step up in the ligament cell in thetubular field for the 52-day test groups. In melatonin added group, proliferating cell nuclear antigen (PCNA)-positivecells were more active. TUNEL assay analysis showed that there was no significant difference between the the 26 dayexperiment groups (p0.05), but that there was a significant dissimilarity between the 52 day experiment groups(p0.05).Conclusions: In our study, the oxidative effect of created by a high voltage results in changes in serum biochemistry ofrats and a number of degenerative deterioration in the histological structure of testes. Aslo, it is shown that theoxidative effect created by a high voltage has negative effects on the creation of spermatogonia. GI partly protectsagainst these effects, while melatonin is more effective in this regard.Giriş: Çalışmanın amacı, yüksek gerilim hattı ile üretilen elektromanyetik alanın testis dokusu ve Wistar albino erkekratların serum biyokimyası üzerindeki etkisini araştırmaktır. Aynı zamanda çalışmada, melatonin ve ganodermalucidum' un koruyucu etkilerinin olup olmadığı da incelenmiştir.Yöntemler: Çalışmada, 64 rat sekiz eşit gruba ayrıldı (n: 8). 26 ve 52 gün süren deneylerde, aşağıdaki gruplarkullanıldı: HV, HVGI, HVMEL ve kontrol. MEL (10 mg/kg) günlük intraperitonal ve GI (20 mg/kg) oral lavaj olarakuygulandı. Oldukça düşük frekanslı elektrik (80.3 V/m) ve manyetik alanlar (2.48 µT) günde sekiz saat süreyleuygulandı.Bulgular: Çalışmanın biyokimyasal sonuçlarında, kontrol grubuna göre 26 ve 52 günlük yüksek gerilim gruplarındatoplam oksidan durum ve oksidatif stres indeksi düzeyindeki artış ve toplam antioksidan durum düzeyinde bir azalmagörülmektedir. Yüksek gerilim gruplarında, maruz kalma süresinin artmasıyla nitrik oksit seviyesi artmıştır. 26günlük karşılaştırmalarda testis ağırlığı (p0.05), TAS, TOS, OSI ve NO (p0.05) bulunmuştur. 52 günlükkarşılaştırmalarda testis ağırlığı, TAS, TOS, OSI (P0.05), ve NO (p0.05) bulunmuştur. Rutin histopatoloji sonucunda,26 ve 52 günlük HV grupları üzerinde, spermatik hücrelerde dejenerasyon ve tam yapısal bozulma ve artanhiyalinizasyon gibi etkiler tespit ettik. Aynı zamanda 52 günlük test grupları için tubülar alanda ligament hücresindebir artış tespit ettik. Melatonin grubunda PCNA-pozitif hücreler daha aktif idi. TUNEL testi değerlendirmesinde, 26günlük test grupları arasında anlamlı bir fark olmadığı (p0.05), ancak 52 günlük test grupları arasında anlamlı birfarklılık olduğu gösterilmiştir (p0.05).Sonuç: Çalışmamızda, yüksek gerilimin neden olduğu oksidatif etkinin, ratların serum biyokimyasında ve testislerinhistolojik yapısındaki bir takım dejeneratif bozulmalarda değişikliklere neden olduğunu göstermektedir. Ayrıca,yüksek gerilimin oluşturduğu oksidatif etkinin, spermatogonia oluşumu üzerinde olumsuz etkileri olduğugösterilmiştir. GI kısmen bu etkilere karşı korurken, melatonin bu konuda daha etkilidir
