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)
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)
The subcutaneous administration of nitrofurantoin to rats caused severe pulmonary damage, characterized by edema, congestion, and hemorrhage. The acute lethality of the drug was greater in rats fed vitamin E-deficient diets high in polyunsaturated fats as compared to rats fed the NIH open-formula diet. The survival times of vitamin E-deficient rats were(More)
A testosterone metabolite, 17 beta-hydroxy-4,6-androstadiene-3-one, possessing an absorbance maximum at 284 nm, was formed during incubation of testosterone with liver microsomes from dexamethasone-treated rats. The metabolite was identified by HPLC, UV spectroscopy, and thermospray liquid chromatography/mass spectrometry. The formation of this metabolite(More)
Four isozymes, designated P-450m50a, P-450m50b, P-450m51a, and P-450m51b, have been isolated from liver microsomes of untreated male CD-1 mice. Electrophoretograms revealed that the molecular weights of P-450m51a and P-450m51b were about 51,000, whereas those of P-450m50a and P-450m50b were about 49,700 and 49,500, respectively. The present study is(More)
