Öğe The effect of chronic microwave irradiation on the rat sperm count and morphology(Pergamon-Elsevier Science Ltd, 1996) Akdag, Z; Celik, MS; Ketani, MA; Deniz, M; Dasdag, S[Abstract Not Available]Öğe The effect of microwave on experimental orthodontic tooth movement(Pergamon-Elsevier Science Ltd, 1996) Karadede, I; Ketani, MA; Akdag, Z; Celik, S; Dasdag, S[Abstract Not Available]Öğe The effect of microwave radiation on morphology of rat epididymidis(Pergamon-Elsevier Science Ltd, 1996) Akdag, Z; Celik, S; Nergiz, Y; Ketani, MA; Dasdag, S[Abstract Not Available]Öğe The effect of microwave radiation on morphology of rat testis(Pergamon-Elsevier Science Ltd, 1996) Nergiz, Y; Akdag, Z; Celik, S; Ketani, MA; Dasdag, S[Abstract Not Available]Öğe Effects of extremely low frequency electromagnetic fields on hematologic and immunologic parameters in welders(Elsevier Science Inc, 2002) Dasdag, S; Sert, C; Akdag, Z; Batun, SBackground. Electric are welding is known to cause considerable exposure to extremely low frequency magnetic fields. Although some studies of exposure to magnetic fields and epidemiologic studies have included groups of welders, typically little information is available concerning the hematologic and immunologic effects of ELF electromagnetic fields on welders. Therefore, the aim of the present study is to investigate whether or not extremely low frequency electromagnetic fields (ELF EMF) emitted from electric arc welding affect sonic hematologic and immunologic parameters of welders. Methods. The study was carried out on 16 male welders and 14 healthy males between 20 and 40 years of age from the same geographic area and with similar life styles. The following hematologic and immunologic parameters were measured in both groups: red blood cells (RBC); hemoglobin (Hgb); hematocrit (Hct); platelets (Plt); total white blood cells (WBC); neutrophils; lymphocytes; eosinophils; and CD3, CD4, CD8, and CD4/CD8. Results. Some of the hematologic and immunologic parameters under investigation were similar in both groups. Although T lymphocyte surface antigens, such as levels of CD4 and CD8 were found to be lower in the welders than in the control subjects (p<0.001, p<0.05), the hematocrit levels of the welders were found to be higher than those of the control subjects(p<0.05). However, the differences observed were not clinically significant. ELF electromagnetic field intensities in the welding areas varied between 0.10 and 0.25 mT. Conclusions. These results suggest that ELF electromagnetic fields do not affect the hematologic and immunologic parameters of welders. (C) 2002 IMSS.

Alveolar and peritoneal exudates from Swiss albino rats were exposed to microwaves for 1, 5, and 10 secs. The results were analyzed with the Mann-Whitney U test. In the group exposed to 2450-MHz microwaves, altered phagocytic activity of macrophages was found to be significant for each exosure period (p <.05). In the groups that were additionally subjected to vitamin C, vitamin E, and combined treatment with vitamin C and dexamethasone, phagocytic activities were found to be changed for only 10 s (p <.05), 1 and 5 s (p <.05), and 1 s (p <.05), exposure, respectively. In the groups exposed to 9450-MHz microwaves alone and microwaves plus vitamin E, altered phagocytic activities were found to be significant for each exposure period (p <.05) and for only 1 s exposure (p <.05), respectively. The differences between pre- and postexposure temperatures were also found to be significant (p < .05).Öğe The investigation of the effect of microwave on rat TMJ(Pergamon-Elsevier Science Ltd, 1996) Karadede, I; Akdag, Z; Ketani, MA; Dasdag, S; Celik, S[Abstract Not Available]Öğe Whole-body microwave exposure emitted by cellular phones and testicular function of rats(Springer, 1999) Dasdag, S; Ketani, MA; Akdag, Z; Ersay, AR; Sari, I; Demirtas, ÖC; Celik, MSThis study investigated whether there are adverse effects due to microwave exposure emitted by cellular phones in male rats. Eighteen Wistar Albino rats were separated into three groups, a sham group and two experimental groups. The rats were confined in Plexiglas cages and cellular phones were placed 0.5 cm under the cages. In the first experimental group, cellular phones were in standby position for 2 h. In the second experimental group. phones were turned to the speech position three times each for 1 min duration over 2 h. Rats in the first and second experimental groups were exposed to microwaves emitted by phones for 2 h/day for a duration of 1 month. After the last exposure the rats were killed. Brain, eyes, ears, liver, heart, lungs, stomach, kidneys, testes. small and large intestines and skill of the rats were observed histologically. The decrease of epididymal sperm counts in the speech groups were not found to be significant (P > 0.05). Differences in terms of normal and abnormal sperm forms were not observed (P > 0.05). Histological changes ut ru especially observed in the testes of rats of the speech groups. Seminiferous tubular diameter of rat testes in the standby and speech groups was found to be lower than the sham group (P < 0.05). Rectal temperatures of rats in the speech group were found to be higher than the sham and standby groups (P < 0.05). The rectal temperatures of rats before and after exposure were also found to be significantly higher in the speech group (P < 0.05). Specific absorption rate (SAR) was determined as 0.141 W/kg.
