ABSTRACT
Moringa leaves and spinach used as vegetables containing cyanogens and polyphenols having suspected antithyroidal activity; however, detailed studies in this aspect found unavailable. Goitrogenic/antithyroid potentiality of those plant foods of Indian origin was evaluated. To explore the goitrogenic/antithyroid effect of those plant foods cyanogenic glucosides, glucosinolates, thiocyanate and polyphenol content were measured. These plant foods were fed with diet regularly to adult male albino rats for 30 and 60 days respectively, followed by evaluation of morphological and functional status of thyroid,as thyroid gland weight, the activity status of thyroid hormone synthesizing enzymes viz. TPO, Na+-K+-ATPase, deiodinase I, thyroid hormone profiles, thyroid histoarchitecture as well as urinary iodine and thiocyanate. In moringa leaves and spinach fed diet, there was a significant increase in urinary excretion of thiocyanate and iodine, enlargement of thyroid gland along with hypertrophy of thyroid follicles and altered in the activities of thyroid hormone synthesizing enzymes with concomitant changes of thyroid hormone profiles. Effects were more severe in moringa leaves treated group than that of spinach. Biochemical analysis moringa leaves and spinach reveal that those are rich sources of goitrogens and their prolonged consumption gradually developed a relative state of biochemical and morphological hypothyroidism.
