“…Tables (3and 4) reveling the effect of local magnetic field on calcium level in all groups of the rabbits and from these results which indicated no noticeable effects of using local pulsed (50 Gauss) magnetic field on serum calcium level and this is could be due to small area of the body of the rabbit will be effected and also the local effect of small field strength and this results agree with results of [ Saygili,1999and Belossi et al, 2000,Pilla 1997,Ohy 2003 as they found no effect of using local magnetic field on blood composition elements, 13,14,15,16 and the results disagree with [Payman, 1995, Tashaev, 1997, Korpinar, 2002,and Peerkhdir, 1995 as they showed decreasing in calcium level in blood serum as they used whole body exposure with greater magnetic field strength in their studies and they contribute this effect with increasing in the metabolic activities of the cells of the tissues and they found a positive effect of magnetic field with bone marrow and immune system 3,4,6,8 .…”

“…Some researchers showed increase in clotting time and decreasing in serum calcium level when the rabbits whole body exposed to a magnetic field for different period of time 2,3,4,6,8 .while in our study all groups showed normal clotting time and calcium level because of the low magnetic field of the implant and the pulsed and static magnetic field used in this study had a local effect on tibiae bone so they showed no systemic effect on clotting time and serum calcium level while previous studies showed increase in clotting time and they correlated that to decreasing in calcium level in the blood which is important ion for coagulation of the blood and its participated in bone tissue calcification 9,10 . So this factor also may be attributed to acceleration of bone healing and coagulation of blood.…”

Studies by Korpinar et al, 2002, on the effect of 300MHz on blood parameters (measured erythrocyte, thrombocyte , leukocyte and coagulation time and their results shows no significant results between all parameters in the studies they showed slight increasing in coagulation time 6 . Frankle et al, 1998 demonstrated that blood, like all tissues, contains electrically charged ions.…”

Background: Many researches indicated that magnetic field had effect on clottingtime and serum calcium level when it was used for stimulation of bone healingand growth. This in vivo study was carried out to evaluate the effect of localpulsed magnetic on clotting time and serum calcium level when used forstimulation of intraosseous implant.Materials and Methods: Forty eight oryctologus cuniculus male rabbits were used inthis study, they divided into two controlled groups and two experimental groupsand each group consist of 12 animals, all experimental groups exposed to (50gauss) pulsed magnetic field strength. Clotting time and calcium level measured atintervals of time (2, 4, 6and 8) weeks of healing periods.Results: the result indicated that theirs no significant differences between thecontrolled group and other groups for (50 Gauss) pulsed magnetic field whichindicate no harmful effect of magnetic field on clotting time and calcium level.Conclusion: The use of (50 Gauss) pulsed magnetic field show no noticeable affecton serum calcium level and clotting time.

Abstract:Purpose: The purpose of this study was to investigate the behavioral changes induced by 50 Hz, 10 mT fl ux density Sinusoidal Magnetic Field (MF). Material and methods: Seventy-six young adult male Wistar albino rats were used in the study. They were separated into two groups: control group (C) n = 38; MF group n = 38. C animals were left under the same conditions with the MF group for 21 days but with prevented or avoided exposure to MF. Anxiety and stress-related behavioral changes were investigated by elevated plus-maze and hole-board systems. Just before being tested in the maze, each animal was tested by means of the hole-board method in order to separate the directed exploration behavior and locomotion activity changes from anxiety-related behavior. Results: In the hole-board system parameters there were no statistically signifi cant differences between the two groups. There was a statistically signifi cant difference between MF and C groups when the ratio of time spent on open arms to the total time spent on all arms was evaluated (0.12 ± 0.08 and 0.34 ± 0.18 respectively and p < 0.01). Conclusion: Our results suggest that after 21 days, a continuous exposure to extremely low frequency of magnetic fi eld (50 Hz, 10 mT) has no signifi cant effect on activity and exploration activity but signifi cantly induces stress and anxiety-related behavior in rats (Tab. 2, Fig. 9, Ref. 19 Static, sinusoidal and specifi c pulsed magnetic fi elds have been shown to alter the animal and human behaviors such as directional orientation, learning, pain perception (nociception) and anxietyrelated behaviors (1 -6).Extremely low frequency (0.1 -100 Hz) of sinusoidal magnetic fi elds (MF) of 50 or 60 Hertz generated predominantly by power lines, appliances and video display terminals could endanger health by producing a variety of effects in biological systems. Appliances can generate fi elds higher than those of transmission lines but in most cases they fall off rapidly. However electric blankets expose the users for eight hours at a time and electric hair dryers and shavers are operated close to the body. Power frequency fi elds carry too little energy in each quantum to break the chemical and molecular bonds, so they are not accepted as a sort of biological damage such as caused by X-rays, but on the other hand they are supposed to induce currents and create potential differences in biological structures.Although the present knowledge is fragmentary and the coherent theory to explain the observations seems far off, continuously present power frequency fi elds in our modern environment bring about potential health effects which are a matter of serious scientifi c and public health policy concern.That concern is focused on cancer and developmental abnormalities and to a lesser extent on endocrine and nervous system and psychiatric problems including anxiety disorders and depression (7 -9).The general aim of our studies is to assess the psychological and psychophysiological effects of low-intensity 50 Hz MF exposure.

“…Results of animal studies didn't show increased cancer risk for long-term exposure to RF fields. The effects of RF waves were also investigated on blood parameters and behavioral changes of rats, obtaining that the frequency is too low to get the resonance effects (Korpinar, Kalkan, Morgul, Birman, & Hacibekiroglu, 1998). Investigations on possible cancer onset were an important research branch which may identify a critical effect of electromagnetic fields.…”

The paper deals with an investigation of the possible effects of RF electromagnetic fields towards the environment and human health. An experimental facility was designed and built and in vitro experiments were carried out on thymic cell cultures. They were exposed for three and six hours to 144 MHz RF electromagnetic fields. The effects were analysed in terms of the possible variation of their thermophysical properties (density, viscosity, specific heat). Results showed that the tested configuration does not induce alterations of the thermophysical properties of the tested cell cultures.
