Influence of levamisole on the capacity of neutrophil granulocytes for ingestion and for the reduction of nitrobluetetrazolium.

With the aid of a modification of the NBT test it has been shown in in vitro and in vivo studies that levamisole does not affect the NBT reduction capacity of neutrophil granulocytes. The increased NBT positivity of these cells under the influence of levamisol is due to stimulation of ingestion.
