ABSTRACT

The effects of ultraviolet (UV-C) irradiation on the plasma total T₃, plasma total T₄ and TSH  hormones of molerats (Spalax leucodon) have been examined. 11 molerats, approximately body weight of 150-200 g were used in experiments. Before the experiments, bloods samples were taken from the animals as control. The animals were exposed to UV-C radiation for 60 days (eight hours a day). At the end of 7^th, 14^th, 21^th, 28^th, 45^th and 60^th days of study, the blood samples were taken from the experimental groups and then total plasma levels of T₃, T₄ and TSH were determined. According to  results obtained from the experiments, the total T₃ and T₄ levels in plasma showed a significant decrease (p<0.001), while TSH level significantly increased  in experimental groups, compared to control.
