Dazoxiben, an orally active specific inhibitor of thromboxane synthetase, was administered by mouth daily to dogs and rats for 6 months. Dogs showed no evidence of toxicity up to 300 mg day-1 kg-1, the highest dose level used. Rats showed no evidence of toxicity after 100 mg day-1 kg-1, but at 300 mg day-1 kg-1 there were slight increases in plasma calcium(More)
An evaluation was made of the different protocols recommended by the Association Française de Normalisation (AFNOR) for assessing the sensitizing potential of chemicals in the guinea-pig. The methods studied were those of Magnusson & Kligman (J. invest. Derm. 1969, 52, 268), Maguire (J. Soc. cosmet. Chem. 1973, 24, 151), Maurer et al. (Agents & Actions(More)
Oxfenicine (S-4-hydroxyphenylglycine) is a cardioselective inhibitor of long-chain fatty acid oxidation. In anesthetized dogs, oxfenicine (3.3 mg/kg, i.v.) increased myocardial blood flow by 33% under normal conditions and by 71% during isoprenaline infusion, but produced no other hemodynamic changes. Similar results were obtained with two other inhibitors(More)
