EFFECT OF ULTRAVIOLET RADIATION ON TOTAL PLASMA T3, TOTAL PLASMA T4 AND TSH HORMONES IN MOLERAT (Spalax leucodon)
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 7th, 14th, 21th, 28th, 45th and 60th 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.
