Abstract
Inhalation of 4500 mg o-xylene [an industrial solvent] by rats produced adaptational and pathologic changes in the liver by the end of wk 1 reflected in increased relative liver weight, shortening of hexobarbital sleeping time, increased concentration of cytochrome P-450, with decreased activities of aniline hydroxylase and aminopyrine N-demethylase. Six wk after start of inhalations all changes in liver and mixed function oxydase system (MFO) were of an adaptational pattern characterized by increased relative liver weight and cytochrome P-450 and b5 concentrations, shortening of hexobarbital sleeping time and increased activity of aniline hydroxylase and aminopyrine N-demethylase.
