Background & aim: Studies show that amphetamines can influence the hypothalamic-pituitary-thyroid axis. The aim of this study was to investigate the effects of Shisheh (met-amphetamine) on serum levels of T3, T4 and TSH in male rats. Methods: In this laboratory experimental study 25 male Wistar rats were randomly divided to control, saline receiving, 2mg/kg, 4mg/kg, and 6mg/kg of Shisheh receiving groups of 5 rats in each. The injection was carried out intraperitoneally once a week for 6 weeks. After serum collection, T3, T4 and TSH levels were measured using ELFA method and the data were statically analyzed using ANOVA. Results: Serum level of T3 and T4 was not significantly changed in rats receiving 2mg/kg of Shisheh compared with control animals. Serum level of T3 and T4 was signifintly increased in animals receiving 4mg/kg and 6mg/kg dose of Shisheh compared with the control rats (P<0.05 , P<0.001, respectively). Serum TSH level was significantly increased in rats receiving 2mg/kg, 4mg/kg, and 6mg/kg of Shisheh compared with control animals (P<0.001). Conclusion: Our results indicate that Shisheh injection can enhance thyroid gland activity via acting on pituitary-thyroid axis, resulting in increased serum T3, T4 and TSH.
Keywords: Shisheh, T3, T4, TSH, Rat.
