When cyanamide and catalase were used to generate NO- in the presence of SOD, NO was measured by the conversion of HbO2 to MetHb.

Inhibition of alcohol dehydrogenase by 4-methylpyrazole or of aldehyde dehydrogenase by cyanamide totally abolished ethanol hepatotoxicity despite of a severalfold increase in acetaldehyde concentration in the perfusate.
Addition of superoxide dismutase or catalase clearly suppressed the ethanol-induced release of GPT and SDH, suggesting that .O2- and H2O2 are involved in this process.

Incubation of benzaldehyde with aldehyde dehydrogenase produced a strong signal that was blocked completely by superoxide dismutase and inhibited partially by catalase, suggesting the presence of superoxide radicals and the involvement of the iron-catalyzed Haber-Weiss reaction leading to the production of hydroxyl radicals.
Pretreatment of rats in vivo with 4-methylpyrazole, an alcohol dehydrogenase inhibitor, or sodium cyanamide, an aldehyde dehydrogenase inhibitor, prior to exposure to toluene, caused a significant decrease and increase, respectively, in toluene-stimulated rates of ROS generation in the CNS and liver.

The oxidation of N-hydroxydebrisoquine by liver microsomes from rats pretreated with dexamethasone not only produced nitric oxide and the urea, but also the cyanamide derivative as the main metabolite.
Experiments with catalase, superoxide dismutase, and H2O2 showed that the O2- formed from the enzyme and the substrate apparently participated in the reaction.

Oxidation of N-(4-chlorophenyl)-N'-hydroxy-guanidine led to the formation of the corresponding urea and cyanamide in addition to NO, NO2-, and NO3-.
