Effect of partial hepatectomy on hepatic metallothionein and glutathione levels and cadmium distribution in different tissues.

abstract：:In recent years, the detrimental effects of high iodine on intelligence are gaining tons of attention, but the relationship between high iodine and neurotoxicity is controversial. This study aimed to explore whether high iodine intake may impair intelligence and the roles of apoptosis and autophagy in high iodine-indu...
