Cinco derivados de 4-trifluorometil-2-(5-aril-3-stiril-1H-pirazol-1il)-pirimidinas e seis 5-aril3-estiril-1-carboxamidino-1H-pirazois previamente sintetizados foram avaliados de acordo com suas propriedades antioxidantes e antimicrobianas. Estas atividades foram avaliadas por ensaios de DPPH e HRP/luminol/H 2 O 2 quimioluminescência e suas atividades antimicrobianas (CIM). Os resultados foram b...
The in vitro effects of metronidazole on the production of reactive oxygen species by polymorphonuclear (PMN) cells were studied by means of nitroblue tetrazolium and luminol-dependent chemiluminescence. At therapeutic doses of metronidazole (4.98-24.86 microg/mL) significant inhibition of the production of reactive oxygen species was noted in both methods. The inhibitory effect was in a dose-d...
In our modification of a chemiluminescence assay to detect chronic granulomatous disease of childhood, whole blood is used and dark-adaptation is not required. This improvement was made possible by the use of luminol as an amplification device and of phorbol myristate acetate as a stimulant. Using this simplified assay, we can assess neutrophil function with 25-100 microL of whole blood, permit...
