چکیده
Thyroid and gonadotropin hormones play an essential role in regulating various physiological functions. The effects of melatonin and zinc (Zn) on these hormones have already been investigated. The current research was aimed to examine the effect of melatonin with and without zinc on the gonadotropin hormones and thyroid hormones (tri-iodothyronine (T3), thyroxine (T4), and thyroid-stimulating hormone (TSH)) levels in female rats. In general, 35 mature female rats were randomly separated into five treatment groups, each group including 7 rats, in a completely randomized design (CRD) during the research. Rats were treated daily by gavage with Zn and melatonin as follows: T1 (control 1, basal diet), T2 (control 2, treated with normal saline), and other experimental groups, including T3, T4 and T5 were treated with doses of Zn (40 ppm), melatonin (5 mg/kg), and combination of Zn plus melatonin with the same level, respectively. The administration of drugs was continued for 20 days (daily) after which the plasma samples were obtained for determination of LH, FFH, LH/FSH, estrogen, progestron, T3, T4 and TSH levels. Results showed no significant variations between treatments in the FSH and LH amounts. Estrogen, progesterone, and TSH levels in rats that received 5 mg of melatonin per day were higher than other groups, but not statistically significant (P>0.05). However, concentration of T3 significantly decreased in the group that received 40 mg/kg of Zn in comparison with other experiments. (P<0.05). The results showed no meaningful deviation among the treatments in T4 level (P>0.05). In conclusion, except for T3, no remarkable changes were observed in other variables in female rats that received melatonin, Zn or a combination of melatonin and Zn.
