A rapid (3-h) arylsulfatase assay for cell suspensions of mycobacteria, in which p-nitrophenyl sulfate is used as the substrate, was developed. Arylsulfatase activity was found in cell suspensions of representative strains of Mycobacterium avium, Mycobacterium intracellulare, and Mycobacterium scrofulaceum grown

Hepatic uptake of the sulfate conjugate of p-nitrophenol (p-NPsul) has been studied. Uptake clearance of p-NPsul by isolated rat hepatocytes was dependent on p-NPsul concentration, suggesting carrier-mediated transport. The uptake of p-NPsul by isolated rat hepatocytes was inhibited by acetaminophen

Subcellular preparations from rat liver, brain, and kidney and from human liver were tested for their ability to desulfate T3 sulfate (T3SO4). Activity was found associated with the microsomal fraction: rat liver was the most active, hydrolyzing 76 pmol/min.mg protein

Although numerous previous reports have characterized the mammalian biotransformation of the organophosphorus insecticides parathion and methyl parathion, questions still remain regarding the toxicological significance of certain metabolic pathways in vivo. The present study utilized rat liver perfusions in order to
