The uptake of estrone sulfate (E1S; 1 to 400 microM), harmol sulfate (HS; 5 to 900 microM), and 4-methylumbelliferyl sulfate (4MUS; 5 to 1000 microM) was investigated in isolated rat hepatocytes in the presence or absence of inhibitors. Uptake of

A direct high-performance liquid chromatographic (HPLC) assay was developed for the separation and determination of 4-methylumbelliferone (4MU) and its glucuronide (MUG) and sulfate (MUS) conjugates in the cell-free perfusate ("plasma") from in situ perfused rat intestine-liver preparation. In addition, a

Arylsulphatase C (ASC) activity in leukocytes and fibroblasts measured with 4-methylumbelliferylsulphate, is caused by at least two genetically different sulphatases. One of these is steroid sulphatase (STS). Depending on the substrate concentration, about 10-50% of the ASC activity in leukocytes

The vascularly perfused rat intestine and liver preparations were used to examine the effect of flow (8 and 10 ml/min) on the sequential metabolism of 4-methylumbelliferone (4MU), which forms primarily the glucuronide conjugate (4MUG) in intestine and the sulfate conjugate
