Abstract
Background and Objective: Electromagnutic field of cell Phones may affect the biological systems. This study was done to evaluate the effect of electromagnutic field of mobile phones on blood pressure, heart rate and arytmia on students of Kurdistan University of Medical Science, in West of Iran. Materials and Methods: In a randomized, double-blind clinical Trial, 56 young healthy volunteers with 20-30 years age were divided in two groups: expousure (n=27) and control (n=29). Cell phone was kept in front of the heart. Non functional cell phone was used in the control group. Systolic and diastolic blood pressure, heart rate and basic ECG were recorded. The Parameters were recorded in stage one (before set on cell phone), stage two (the first 5minutes), stage three (6minutes,with silent ringing), stage four (after 17min conection) and stage five (after 35 min conection). In all Stages, it was evaluated by cardiac monitoring (Lead2) for the presence of (sinus arryhthmia, sinus bradycardia, SA block, AV block, PAC and PVC). Results: Systolic and diastolic blood pressure and heart rate did not show to have any significant differences between two groups in any stages. Rate of sinus arryhthmia was higher in expousure group at stages four and five, but only in stage four, this difference was shown to be significant (P<0.05). Conclusion: The findings of this study showed that, electromagnetic of cellular phone cause sinus arryhthmia after 17 minute connection, to prevent the side effect of cell phone, we suggest that, cell phone set distant away from heart and reduce the connection time.

Abstract
Background and Objective: The electromagnetic field producer sets in daily life causes concerns about the adverse effects of such waves on human health. This study was done to evaluate the effect of cell phones microwaves on histologic structures of some visceral organs in rat.
Methods: In this experimental study, 80 immature Wistar male rats with weight of 100-140 gram and 5 to 6 weeks age were randomly allocated into 3 experimental groups and one control group. The experimental rats were exposed to cell phones microwaves 5 hours a day for 1, 2 and 3 months. The control group received no radiation. After the experimental period rats were sacrificed and the appropriate tissues of the lung, heart, liver, brain and pancreas were prepared. Sections in 5 µm thicknesses were stained by hematoxylin and eosin and studied microscopically.
Results: Histological changes including edema, inflammatory cell infiltration and cell degeneration in the lung and mild degeneration and coagulation necrosis of the myocardial cells in the heart were observed. Histopthological examination of the liver revealed dilation of central veins and sinusoids, vacuolization of hepatocytes and mononuclear inflammatory cell infiltration. Limited changes were observed in pancreas and brain. Histological changes were increased in the groups that were exposed longer period of time to radiation.
Conclusion: This study indicated that the harmful effect of cell phones radiation on rat tissues depending on the duration of exposure.

Abstract
Background and Objective: The increasing usage of cell phones, have raised concerns about the potential effects of these waves on the health of individuals. In the present research the effect of mobile phone radiation on the expression of DAZL gene in BALB/c mice were studied.
Methods: 18 male mice were divided into three groups: Control, sham-exposed and experimental. Experimental mice were exposed to mobile waves for 2 hours daily, during 3 weeks. After 3 weeks, the testes were excised and RNA extraction and Real-Time PCR were performed. Sperm counts in deferen channel and the study of sperm motility in epididymis were done.
Results: The percentage of non-progressive sperm motility significantly increased in experimental group in compared to control group (P<0.05).The level of DAZL gene expression in the experimental group was significantly lower than the control group (P<0.05). Weight of the testis, percentage of live sperm, percentage of rapid progressive sperm motility and percentage of slow progressive sperm motility non-significantly reduced in experimental group in comparison with controls.
Conclusion: Exposure to cell phone waves for 21 days and 2 hours a day impairs spermatogenesis by reducing the quality and motility of sperm and also reduction of expression of DAZL gene.
