Abstract
Background and Aim: Thyroid gland makes thyroxine (T4) and triiodothyronine (T3) hormones. These hormones are really effective in regulating and control of basal metabolism. The purpose of this study was to assess the effect of hydroalcoholic extract of Terfezia Boundary (TB) on the serum level of thyroid hormones.
Methods & Materials: In this experimental study, 30 male Wistar rats (weighing 200±10 g) were selected and divided into five groups of 6 including control, sham (received normal saline) and three experimental groups received TB with 75, 150 and 300 mg/kg doses via intraperitoneal injection for 14 days. Samples from all groups were collected at the end of the 14th day directly from the heart to evaluate thyroid hormone. The data were statistically analyzed in SPSS v. 12.
Ethical Considerations: This study was approved by the Research Ethics Committee of Ardabil University of Medical Sciences (code: IR.ARUMS.REC.1396.48).
Results: The results of this study showed that the T3 and T4 levels in the experimental groups 2 (150 mg/kg) and 3 (300 mg/kg) increased significantly compared to the control group (P<0.001 and P<0.01, respectively). The Thyroid Stimulating Hormone (TSH) level in the experimental groups 1 (75 mg/kg), 2 (150 mg/kg) and 3 (300 mg/kg) decreased significantly compared to the control group (P<0.05, P<0.001, P<0.001, respectively).
Conclusion: Hydroalcoholic extract of TB can increase the serum levels of thyroid hormones and reduce TSH level.

Abstract
Introduction: Nowadays, due to the increasing spread of electronic devices and digital transmitters, the general public is exposed to electromagnetic waves with different wavelengths. According to the function of the thyroid gland on the metabolic actions of the body, the purpose of this study was to investigate the changes in the serum level of thyroid stimulating hormone after receiving short-term and long-term electromagnetic waves emitted from home Wi-Fi.
Methods: 60 rats in the weight range of 250-300 grams were randomly divided into 3 equal groups. The first group did not receive any waves. The second group was placed near Irancell's portable Wi-Fi device for 10 days,1 hour a day, and the third group was near Wi-Fi waves for 3 hours a day for a month. After one month, blood was taken from the mice and the serum level of thyroid stimulating hormone was measured.
Results: The data analysis showed that the serum level of thyroid stimulating hormone in the group that was exposed to medium-term Wi-Fi waves was significantly different from the control group, but the level of this hormone in the group that was exposed to the waves for a short period of time, it was not significant in comparison with the control group.
Conclusions: According to the present results, it is possible that electromagnetic waves lead to hormonal disorders in the body, and one of these disorders can be a change in the amount of thyroid stimulating hormone.
