title: No effect of prolonged fluoride exposure on cytochrome P-450 and associated monooxygenases or on the level of polyamines in the rat.
abstract: When exposing rats to drinking water containing 100 p.p.m. fluoride for 8 weeks, no effect could be detected in biochemical parameters of the liver, such as the concentrations of the polyamines putrescine, spermidine and spermine; the levels of microsomal protein and cytochrome P-450; or the activities of two associated monooxygenases, aryl hydrocarbon hydroxylase and ethylmorphine N-demethylase. Neither was there any increase in plasma glutamic-oxalacetic transaminase indicative of liver damage.
