【 摘 要 】

Adiantum capillus-veneris L., Pteridaceae, is a fern reputed to have numerous applications in traditional medicine in the treatment of leprosy, animal bites, thyroid dysfunction and musculoskeletal disorder.The proposed study was aimed to investigate the potency of the fern Adiantum capillus-veneris on the thyroid dysfunction - hypothyroidism in terms of determining thyroid gland weight, thyroid peroxidase activity, estimation of iodine in urine, concentrations of total thyroxine (T4), triiodothyronine (T3) and thyroid stimulating hormone (TSH) in serum. The weight of thyroid gland was decreased, while thyroid peroxidase activity, serum T4 (p < 0.01) and serum T3 levels (p < 0.01) were increased in animals treated with the ethanol plant extract (500 mg/kg); but serum TSH level decreased significantly (p< 0.01) when compared with hypothyroid control animals. The SOD, Catalase and glutathione antioxidant enzyme levels and lipid peroxidation were measured.The results of lipid peroxidation and antioxidant enzyme assay indicated that the level of malondialdehyde was significantly lowered and the levels of antioxidant enzymes were significantly increased when treated with ethanol extract of Adiantum capillus(500 mg/kg). Polyphenolic compounds viz., quercetin and gallic acid were determined by HPTLC analysis. With the outlined results, Adiantum capilluscould be used for the regulation of hypothyroidism.
