FORMALDEHYDE METABOLISM UNDER SEMICARBAZIDE INTOXICATION
Palladin Institute of Biochemistry, National Academy of Sciences of Ukraine, Kyiv;
Subchronic administration of semicarbazide in the experiment with the rats was used to reduce the formaldehyde level in the organism in order to reveal the interaction between formaldehyde metabolism and biochemical parameters, which define the oxidant-antioxidant system condition and NO metabolism. It has been found that under semicarbazide impact the generation of free radicals, ROS, nitrite and nitrate were enhanced while aldehydes level was reduced that resulted from not only semicarbazide effect like the aldehydes acceptor, but the formaldehyde synthesis slowdown and acceleration of its transformation into format as well. We suppose that formaldehyde plays certain role in the development of connective tissue pathology.
Key words: semicarbazide, formaldehyde, nitric oxide.
