Abstract
BACKGROUND AND OBJECTIVE: Celery (Apium graveolens) is a medicinal plant with antioxidant benefits and rich of flavonoid. Since flavonoids have great impact on physiological functions of body and especially thyroid function, the aim of this study was to investigate the effect of hydro- alcoholic extract of celery leaf on serum level of thyroid hormones. METHODS: In this experimental study, 40 male rats were divided into 5 groups of eight rats each. They were control, sham (received normal saline) and the experimental groups received 1 ml of hydro- alcoholic extract of celery with doses of 50,100 and 200 mg/kg during 21 days by using gavage method. One day after the last gavage, the blood samples were collected by bloodletting from the heart. After preparing serum, the level of T3، T4 and TSH hormones were measured using ELISA method. FINDINGS: The serum levels of T3 (0.95±0.04 and 0.95±0.06, respectively) and T4 (5.42±0.85 and 5.87±0.89, respectively) hormones decreased (p0.05). CONCLUSION: The results showed that prescribing these doses of celery extracts caused the decrease of thyroid hormone level so it could be considered as a balance hyperthyroidism.
