Peroxidative damage to DNA initiated by methyl ethyl ketone peroxide, a potent initiator of lipid peroxidation, and protection against this damage by vitamin E were studied in rats. Groups of rats were fed a casein-based diet that contained 10% tocopherol-stripped corn oil and either 0, 3, 5, or 10

Methyl n-butyl ketone (MnBK), methyl isobutyl ketone (MIBK), methyl ethyl ketone (MEK), and acetone are widely used industrial solvents to which certain groups of workers are exposed. Pharmacological and metabolic interactions between these solvents and ethanol were explored in male CD-1 mice. The

One useful method to monitor in vivo lipid peroxidation is the measurement of volatile hydrocarbons, mainly pentane and ethane, that derive from unsaturated fatty acid hydroperoxides. Vitamin E, the biological antioxidant, inhibits lipid peroxidation and the production of pentane and ethane. The

Weanling male Sprague-Dawley rats were fed diets for four weeks which differed in their content of n-6 (corn oil; CO) and n-3 fatty acids (fish oil; FO), but were similar in their content of saturated and monounsaturated fatty acids and vitamin E. At the end of the four-week feeding period, each

Pseudopregnant and cyclic rats were injected for 5 to 26 days with daily doses of 5 and/or 3 mg of 5-bromo-2-thienyl-ethyl-ketone thiosemicarbazone (70026) starting on Day 0 (the day of oestrus). The vaginal smear cytology, record of ovulation and ability to breed and conceive were compared with the

Previous results in male Sprague-Dawley rats indicate that acetone (A), methyl ethyl ketone (MEK), and methyl isobutyl ketone (MiBK) pretreatments (3 d, p.o.) at a dosage of 6.8 mmol/kg potentiate CCl4 hepatotoxicity. The potentiation potency profile observed was MiBK > A > MEK. In the present
