We have isolated a cDNA clone, Nah-2, encoding the cytochrome P-450Nah (naphthalene hydroxylase) from a mouse lung lambda ZAP cDNA library using anti-cytochrome P-450Nah IgG as a probe. This same antibody selectively blocked [Nagata, K., Martin, B.M., Gillette, J.R., & Sasame, H.A. (1990) Drug Metab. Dispos. 18, 557-564] the cytochrome P-450 in mouse lung(More)
The possibility that furosemide-induced hepatic necrosis results from the formation of a chemically reactive hepatotoxic metabolite has been examined. Hepatotoxic doses of 3H-furosemide or 14C-furosemide were administered to normal mice and to mice pretreated with piperonyl butoxide, cobalt chloride, alpha-naphthylisothiocyanate or phenobarbital. Mice were(More)
In laboratory rodents, concentrations of reduced glutathione (GSH) are exceedingly high (up to 7 to 8 millimolar) in the glandular gastric tissue compared to concentrations in other portions of the gastrointestinal tract or to those of most other organs. Gastric GSH varies diurnally, with the highest levels occurring in the late afternoon or early evening.(More)
