Prior knowledge of communications between these two neighbouring nerves, both in terms of their incidences and pattern of communications, may be of considerable significance to neurologists and orthopaedicians in dealing with nerve entrapment syndromes in the upper limb of patients.

Background: The study aims to reveal the effect of 2100 MHz radio frequency radiation on thyroid tissues of the rats in early and late groups. Material and Method: In this study, 30 healthy female Wistar albino rats, weighting 200 to 256 g each were used. The animals were randomly divided into four groups (groups E1, E2, G1, G2). Groups E2 and G2 served as the control groups. The exposure groups were exposed to 2100 MHz radiofrequency radiation emitted by a generator, simulating a 3G-mobile phone for 6 hours /day, 5 consecutive days/ week, at the same time of the day (between 9 am-3pm), for 10 days (group E1) and 40 days (group G1). Results: Catalase and xanthine oxidase enzyme activities were compared between the groups E1 and E2, it was found that the difference was statistically significant (p<0.05). Between the groups G-1 and G-2 the difference was found to be significant with respect to catalase activities. The early and late groups tissue samples showed no serious pathological findings in the histopathological examination. Conclusion: We believe that comprehensive, clinical and experimental studies, are needed to assess how effective the RF exposure duration and dosage of exposure on thyroid tissues.
