Plasma levels of sulfinpyrazone and of two of its metabolites after a single dose and during the steady state
The pharmacokinetics of sulfinpyrazone, and the plasma levels of its sulfide and sulfone metabolites, have been determined after a single oral dose (400 mg) and during steady-state conditions (4×200 mg daily f...

Spectrophotometric characteristics and assay of pure pyronin Y
The spectrophotometric characteristics of analytically pure pyronin Y have been investigated. Addition of metal ions (Fe3+, Zn2+, and Mg2+) and of dextrin were shown not to influence the absorption characteristic...

Preparation and characterization of methyl green tetrafluoroborate
Commercial methyl green dyes were converted to tetrafluoroborate by means of NaBF4-solution, the compounds thus obtained were analytically pure. It was shown to be possible to distinguish between a “methyl” and a...

Nucleic acid staining with the methyl green-pyronin method
We compared the staining obtained using commercially available pyronin Y samples with that obtained using pure pyronin Y in a standardized methyl green-pyronin procedure. In addition, the importance of the dye...
