comparative toxicokinetic/toxicodynamic study of rubber

Comparative toxicokinetic/toxicodynamic study of rubber

2-Mercaptobenzimidazole (MBI), a rubber antioxidant, is known to exhibit potent thyroid toxicity in rats, whereas its methylated derivatives are much less toxic. To characterize this methyl-substituent effect on the thyroid toxicity of MBI, comparative toxicokinetic analyses have been conducted in the present study.
