Abstract
The effects of dapsone (diaminodiphenyl sulfone) on the polymorphonuclear leukocyte (PMNL) function and on the elicitation of the passive Arthus reaction were investigated in rabbits and guinea-pigs. NBT-reduction was markedly enhanced in PMNL of animal receiving 5 mg dapsone/kg for 3 days, whereas chemotaxis and phagocytosis were not influenced. Passive Arthus reaction was clearly suppressed by the same treatment regimen. 2 mg/kg of the drug had no effect on the parameters examined. Wir untersuchten den Effekt von Dapsone auf die Granulocytenfunktion und die passive Arthusreaktion bei Kaninchen und Meerschweinchen. 5 mg Dapsone/kg über 3 Tage führten zur erheblichen Steigerung der NBT-Reduktion in Granulocyten; die Chemotaxis und Phagocytose wurden nicht beeinflußt. Die gleiche Dosis führte zur Unterdrückung der passiven Arthusreaktion. 2 mg/kg des Medikaments hatten keinen Effekt auf die untersuchten Parameter.Keywords
