The Effects of Melatonin on Oxidative Stress Parameters and DNA Fragmentation in Testicular Tissue of Rats Exposed to Microwave Radiation

Sokolovic D, Djordjevic B, Kocic G, Stoimenov TJ, Stanojkovic Z, Sokolovic DM, et al. The Effects of Melatonin on Oxidative Stress Parameters and DNA Fragmentation in Testicular Tissue of Rats Exposed to Microwave Radiation. Adv Clin Exp Med. 2015 May-Jun;24(3):429-36. doi: 10.17219/acem/43888.


BACKGROUND: Microwaves from mobile phones are one of the environmental toxicants that are capable of compromising male fertility by inducing oxidative stress and apoptosis in the testes. Melatonin is a lipophilic tryptophan indole amine and a potent antioxidant.

OBJECTIVES: The aim of the study was to evaluate the effect of melatonin treatment on oxidative stress parameters and DNA fragmentation in the testicular tissue of rats exposed to microwave radiation (4 h/day).

MATERIAL AND METHODS: Adult Wistar rats were divided in 4 groups: I - treated with saline; II - treated with melatonin; III - exposed to microwaves; IV - exposed to microwaves and treated with melatonin. The melatonin (2 mg/kg ip) was administered daily. The animals were sacrificed after 20, 40 and 60 days.

RESULTS: Melatonin treatment prevented previously registered increases in malondialdehyde after only 20 days. Furthermore, it reversed the effects of microwave exposure on xanthine oxidase (after 40 days) and acid-DNase activity (after 20 days). However, neither protein carbonyl content nor catalase and alkaline Dnase activity were changed due to melatonin treatment.

CONCLUSIONS: Melatonin exerts potent antioxidant effects in the testes of rats exposed to microwaves by decreasing the intensity of oxidative stress; it also reduces DNA fragmentation.


The animals were exposed to MWs for 20, 40 and 60 days (4 h per day during the light period). The MWs were produced by a Nokia 3110 mobile test phone (Nokia Mobile Phones Ltd.) .... During MW exposure, 8  rats were able to move freely in a  100% plastic cage without any metallic fittings. A  continuous wave near-field electromagnetic signal (900 MHz) for the Global System for Mobile Communication (GSM) was used for the purposes of the experiment ... Electric field intensity (E) ranged from 9.88 V/m  to 18.356 V/m, and magnetic field intensity (B) ranged from 4.68 mT to 8.69 mT. The whole-body specific energy absorption rate (SAR) was estimated at 0.043–0.135 W/kg using data for a rotating ellipsoidal rat model.

The animals were divided in 4 experimental groups. Each group consisted of 21 animals housed in 3 cages (7 animals in each). Group I (the control group) consisted of rats treated with 0.9 % saline; Group II (Mel) consisted of rats treated with melatonin (2 mg per kg–1 body weight by IP injection); Group III (MWs) comprised rats exposed to MWs; and Group IV (MWs + Mel) was made up of rats exposed to MWs and treated with melatonin (2 mg per kg–1 body weight by IP injection). The melatonin was administered every morning at 08.00 AM. as proposed by Drago et al. [14]. The melatonin was administered intraperitoneally in a single dose of 2 mg/kg–1 in order to avoid the neuromodulatory effect of melatonin. In the control rats, isotonic saline solution (equal to the volume of melatonin) was given intraperitoneally every day during the follow-up.

According to the results of the present study, melatonin caused a significant decrease in oxidative stress intensity, reflected in the decrease in MDA levels. In addition to this, melatonin caused a  reversal of the effects of MW radiation on XO activity in the testicular tissue, lowering XO-induced oxidative stress. On the other hand, melatonin showed no significant ability to reverse the effects of MW exposure on catalase levels in testicular tissue. However, melatonin caused a  significant decrease in acid DNase activity, reflecting reduced amounts of apoptosis in the testicular tissue exposed to MWs. In conclusion, melatonin exerts potent protective effects in the testes of rats exposed to microwaves by decreasing oxidative stress intensity and DNA fragmentation.

This review aims to cover experimental data on oxidative effects of low-intensity radiofrequency radiation (RFR) in living cells.
Analysis of the currently available peer-reviewed scientific literature reveals molecular effects induced by low-intensity RFR in living cells; this includes significant activation of key pathways generating reactive oxygen species (ROS), activation of peroxidation, oxidative damage of DNA and changes in the activity of antioxidant enzymes. It indicates that among 100 currently available peer-reviewed studies dealing with oxidative effects of low-intensity RFR, in general, 93 confirmed that RFR induces oxidative effects in biological systems. A wide pathogenic potential of the induced ROS and their involvement in cell signaling pathways explains a range of biological/health effects of low-intensity RFR, which include both cancer and non-cancer pathologies.
In conclusion, our analysis demonstrates that low-intensity RFR is an expressive oxidative agent for living cells with a high pathogenic potential and that the oxidative stress induced by RFR exposure should be recognized as one of the primary mechanisms of the biological activity of this kind of radiation.

The analysis of modern data on biological effects of lowi-ntensity RFR leads to a firm conclusion that this physical agent is a powerful oxidative stressor for living cell. The oxidative efficiency of RFR can be mediated via changes in activities of key ROS-generating systems, including mitochondria and non-phagocytic NADH oxidases, via direct effects on water molecules, and via induction of conformation changes in biologically important macromolecules. In turn, a broad biological potential of ROS and other free radicals, including both their mutagenic effects and their signaling regulatory potential, makes RFR a potentially hazardous factor for human health. We suggest minimizing the intensity and time of RFR exposures, and taking a precautionary approach towards wireless technologies in everyday human life.

Altro disintossicante ... nuovo: la vitamina C

Recentissimo lavoro in cui si dimostra  l'azione protettiva della vitamina C dallo stress ossidativo provocato da radiofrequenze.

Vitamin C protects rat cerebellum and encephalon from oxidative stress following exposure to radiofrequency wave generated by a BTS antenna model

Akbari, A., Jelodar, G., Nazifi, S. Vitamin C protects rat cerebellum and encephalon from oxidative stress following exposure to radiofrequency wave generated by a BTS antenna model. Toxicology Mechanisms and Methods. 24(5):347-352. Jun 2014. DOI: 10.3109/15376516.2014.910852
Radio frequency wave (RFW) generated by base transceiver station has been reported to produce deleterious effects on the central nervous system function, possibly through oxidative stress. This study was conducted to evaluate the effect of RFW-induced oxidative stress in the cerebellum and encephalon and the prophylactic effect of vitamin C on theses tissues by measuring the antioxidant enzymes activity, including: glutathione peroxidase, superoxide dismutase, catalase, and malondialdehyde (MDA). Thirty-two adult male Sprague-Dawley rats were randomly divided into four equal groups. The control group; the control-vitamin C group received L-ascorbic acid (200 mg/kg of body weight/day by gavage) for 45 days. The RFW group was exposed to RFW and the RFW+ vitamin C group was exposed to RFW and received vitamin C. At the end of the experiment, all groups were killed and encephalon and cerebellum of all rats were removed and stored at -70 degrees C for measurement of antioxidant enzymes activity and MDA. The results indicate that exposure to RFW in the test group decreased antioxidant enzymes activity and increased MDA compared with the control groups (p<0.05). The protective role of vitamin C in the treated group improved antioxidant enzymes activity and reduced MDA compared with the test group (p<0.05). It can be concluded that RFW causes oxidative stress in the brain and vitamin C improves the antioxidant enzymes activity and decreases MDA.

Calcio ionizzato : chiave per possibile cura degli effetti

E' stato rilanciato il lavoro del Prof Andrew Goldsworthy   che ha sviluppato  la relazione tra campi elettromagnetici e perdita di calcio dalle membrane cellulari. 

Importante la conclusione:

si può combattere gli effetti curando la ipocalcemia derivante, assumendo calcio.

Io posso dire è ciò che mia moglie e mio figlio stannno facendo da anni.

Avete fatto un test sul calcio inonizzato nel sangue ?

One Page Summary of Andrew Goldsworthy ‘The Biological Effects of Weak Electromagnetic Fields’
What the power and telecoms companies would prefer us not to know
-- Andrew Goldsworthy , 2007
§  Weak electromagnetic fields release calcium from cell membranes
§  The loss of calcium makes cell membranes leak
§  How calcium loss makes holes in membranes
§  Membrane leakage damages DNA
§  DNA damage may cause cancer
§  DNA damage reduces fertility
§  There may also be permanent genetic damage
The power and mobile phone companies have seized upon this characteristic
variability to discredit work on the non thermal effects of electromagnetic fields as
being due to the experimental error. Nothing could be further from the truth. Many of
these experiments are highly reproducible, especially the fundamental and all important
ones on the effects of the radiation on the release of calcium from cell
membranes. Secondary effects further down the line may be less reproducible since
they are more likely to be mitigated by the intervention of cellular defence
mechanisms. Therefore, we cannot expect rigidly reproducible results in all
circumstances any more than we can expect everyone to experience exactly the same
side effects from taking a medicinal drug. However, that does not mean that they can
be safely ignored!
In the latter part of this article, I have explained how weak electromagnetic fields can
interact with cell membranes to weaken them and make them more permeable. …There is undeniable experimental proof that weak electromagnetic fields can remove bound calcium ions from cell membranes. There is also no doubt that bound calcium ions are essential for the stability of these membranes. Consequently, their loss will increase temporary pore formation under the mechanical stresses from pressure differences within the cell and abrasion by its moving contents. This very simple conclusion can account for virtually all of the known biological effects of electromagnetic fields, including changes in metabolism, the promotion of cancer, genetic damage, loss of fertility, deleterious effects on brain function and the unpleasant symptoms experienced by electrosensitive individuals.
Electrosensitivity and hypocalcemia – a possible cure
However, it seems possible that at least some cases electrosensitivity could be due to
low levels of ionised calcium in the blood exacerbating the electromagnetic effects. If
so, it may be possible to relieve some or all of the symptoms by conventional
treatment for hypocalcemia.
