[Increased leukopoietic effect of 2-cyanoethylurea by doubling the oxygen concentration of the air].

Abstract

In Wistar rats the sure leukopoietic effect of 165 mg/kg-1 of 2-cyanethylurea was found to be increased distinctly and in some cases significantly by doubling the O2 shares of inhaling air to 42%. Small lymphocytes are the main carrier of this effect. The potential immunological relevance of the findings is referred to.
