Abstract

Background:

There are previous independent reports on the anti-thyroid property of Citrus sinensis. This isoflavones and phenolic acid-rich natural agent is widely consumed as dietary supplement, thus the need to investigate its comparative effect with a standard anti-thyroid drug on T₄, T₃ and thyroid stimulating hormone (TSH) levels.

Objective:

To compare the effect of Citrus sinensis and carbimazole (CARB) on blood levels of thyroid hormones (T₄ and T₃) and TSH.

Materials and Methods:

Male wistar albino rats weighing 100-150 g were employed in this research. The rats were randomly assigned to four groups of seven rats per group. Group I served as control and were administered distilled water while groups II-IV were administered with 1500 mg/kg of Citrus sinensis (fresh orange juice; FOJ), 0.1 μg/g of levothyroxine (LVT) and 0.01 mg/g of CARB, respectively, per oral once daily for 28 days. The animals were sacrificed under chloroform anaesthesia and blood sample collected by cardiac puncture and processed by standard method to obtain serum. TSH, T₄ and T₃ were assayed with the serum using ARIA II automated radioimmunoassay instrument.

Results:

The results showed that TSH level was significantly (P < 0.05) decreased in LVT treated group compared with the FOJ group. T₄ was significantly (P < 0.05) decreased in the FOJ and CARB groups compared with the control and LVT groups. LVT significantly increased T₄ when compared with FOJ group. T₃ was significantly (P < 0.05) decreased in the CARB group compared with the control.

Conclusion:

These findings suggest that FOJ alters thyroid hormones metabolism to reduce their serum levels with a compensatory elevations of TSH level in a direction similar to CARB.
