This 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 skin 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 were 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.

In tlzis study, we investigated tl1.e blological effects oj' RF (Radio Frequency) and microwave in terms oj'neurologica/ and bloc/zemicaljindings, and CD4jCD8 ratio in people tlzat work at broadcasting and tele-..•ision transmitter stations. Tlze study was carried out on 26 people j'rom 20 to 49 years oj' age, occupationally exposed to nonionizing radiation. First we gave out а questiomzaire consisting oj' 12 questioш to e\•erybody under im•estigation Secondly, we determined tlze levels oj' АLТ, АSТ, LDH, ALP, СК, plюsp/юrus, tota/ protein, albumin clюlesterol, uric acid, urea, creatinin, Na, К, and NSE (Neuron Specific Enolase), and also CD4jCD8, albuminjglobulin ratios and percentage oj' serum proteins. Tlze results obtained in tlzis study were statistically compared to а control group.
