3.2. Effects of UVB irradiation on thyroid hormones
Thyroid hormone levels are noticeably higher in the UVB-irradiated group
compared to the control group. T3, T4, fT3, and fT4 levels significantly
increased in the UVB-irradiated group compared to the control group,
while TSH levels significantly decreased. As shown in figure 3, the
UVB+NG treated group’s T3, T4, fT3, and fT4 levels were significantly
lower than those of the UVB irradiated group, and the administrative NG
group exhibited substantial differences from the control group.
