The purification and properties of an enzyme from Nocardia sp. which catalyses the conversion of p-hydroxybenzonitrile to p-hydroxybenzoic acid and ammonia without intermediate formation of the amide is described. The enzyme displayed a broad pH optimum between 7.0 and 9.5
The purpose of this work was to analyse the mechanism of the enhancement of percutaneous penetration demonstrated by the known enhancers Azone and Transcutol. Enhancer induced changes in the diffusivity and solubility of a model permeant (4-cyanophenol) in human stratum
Simple, safe and quick in vivo methods for estimating chemical uptake into the stratum corneum (SC) from volatile and non-volatile solvents are invaluable to health risk assessors. This study compares the human in vivo SC uptake of a model compound

Attenuated-total-reflectance Fourier-transform-infrared spectroscopy has been used to rapidly and noninvasively quantify in vivo the uptake of a chemical into the outermost, and least permeable, layer of human skin (the stratum corneum). The objective of the experiment was to develop a
Attenuated total-reflectance infrared (ATR-IR) spectroscopy has been used to follow the penetration of a model compound (4-cyanophenol; CP) across human stratum corneum (SC) in vivo, in man. CP was administered for periods of 1, 2, or 3 hr, either (a)
