The reaction of o-aminophenol with para hydroxy and methoxy substituted benzaldehydes yielded two Schiff bases. These bases functioning precursors were turned into palladium complexes by treating acetate. structural formulas based on spectral methods (elemental analysis, FT-IR spectroscopy, NMR spectroscopy QTOF-LC/MS spectroscopy) suggested for obtained both complexes. According to the charact...

BACKGROUND Hair dye products constitute an important source of allergen exposure, and contribute importantly to allergic contact dermatitis in consumers and hairdressers. OBJECTIVES To evaluate the presence of potent contact sensitizers in oxidative hair dye products intended for home use on the US market. METHODS Ingredient labels of 107 hair dyes from 10 major brands were examined and use...

The ability of the liver to form glucuronides was measured in 10 patients with infectious hepatitis. One test was done at the onset and another about four weeks later after the clinical symptoms had disappeared. N-acetyl-p-aminophenol (N.A.P.A.) or acetanilide was administered in doses ranging from 10 to 20 mg. per kg. body weight, either orally or by intravenous injection. N.A.P.A. is conjugat...

1. A precocious development of UDP-glucuronosyltransferase activity (EC 2.4.1.17) towards o-aminophenol is demonstrated in 15-17 day foetal rat liver in utero after dexamethasone administration to the mother. 2. This stimulation of liver transferase activity in utero is directly proportional to the dose of dexamethasone infected. 3. Precocious development of transferase activity in utero can al...
