Diepoxybutane is one of the key metabolites of butadiene, a compound of high environmental and occupational concern. The effects of diepoxybutane on mouse reproductive cells have been previously characterized by flow cytometry demonstrating a specific, dose-dependent cytotoxicity for differentiating spermatogonia.

Phorone, a glutathione (GSH) depletor, induces the expression of mRNAs of heme oxygenase-1 (HO-1) and c-jun by mediating the activation of activated protein-1 (AP-1) in rat livers. We have shown that phorone activates c-Jun N-terminal kinase (JNK), thus leading to

The seleno-organic compound ebselen mimics the glutathione-dependent, hydroperoxide reducing activity of glutathione peroxidase. The activity of glutathione peroxidase determines the rate of hydroperoxide-induced Ca2+ release from mitochondria. Ebselen stimulates Ca2+ release from mitochondria, accelerates mitochondrial respiration and uncoupling, and induces

The aim of this study was to investigate the role of metabolic activation in the olfactory toxicity of methyl iodide (MeI). Adult male rats were exposed via nose-only inhalation to 100 ppm MeI for 0-6 h, and non-protein sulphydryl (NP-SH)

Previously we reported that methylsulphonyl-2,6-dichlorobenzene, 2, 6-(diCl-MeSO(2)-B), was irreversibly bound to the olfactory mucosa of mice and induced necrosis of the Bowman's glands with subsequent neuroepithelial degeneration and detachment. In this study, autoradiography and histopathology were used to determine tissue-localization
