antithyroid/zea mays

BACKGROUND Tributyltin is one of the important and wide-spread persistent organic contaminants that accumulate in the food chain. It is suspected to cause endocrine-disrupting effects in mammals, due in part to its possible transfer through marine food chains and to the consumption of contaminated

Thyroid hormones have been implicated in the toxicity of 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD). Therefore, the effects of methimazole (MMI) and propylthiouracil (PTU) induced hypothyroidism and surgical thyroidectomy on several toxic manifestations of TCDD were investigated. Female rats were

2-Mercaptobenzimidazole (2-MBI), a rubber antioxidant, is known to exhibit potent antithyroid toxicity in rats and is a candidate as an environmental endocrine disrupter. 2-Mercaptomethylbenzimidazoles (a 1:1 mixture of 4-methyl and 5-methyl isomers, MMBIs), are also employed industrially as rubber
