In addition, methylation of N7 guanine was found to be 50-fold higher in one study following oral administration of UDMH to rats, when compared to the corresponding data for daminozide.
Dertil kom, at methyleringen af guanin N7 i én undersøgelse var 50 gange højere efter peroral administration af UDMH til rotter end den, der ifølge de tilsvarende data for daminozid var konstateret for dette stof.
