[Damage to the liver DNA of rats during the endogenous synthesis of N-nitrosodimethylamine]. 1986

V M Mikhaĭlenko, and M A Furman

The damage of liver DNA formation during endogenic synthesis of N-nitrosodimethylamine (NDMA) have been studied after introduction of its precursors, dimethylamine, amidopyrine and sodium nitrite, into the rat stomach. A combined administration of various doses of dimethylamine and nitrite increased the amount of single-strand DNA from 3.0 to 11.3%. The maximum DNA damage after administration of the precursors was observed after 24 h, and after 48 h it decreased to the control level. Pretreatment of rats with dimethylamine or nitrite increased the DNA damage induced by NDMA formation (37.4% and 41.6%, respectively).

D008099 Liver A large lobed glandular organ in the abdomen of vertebrates that is responsible for detoxification, metabolism, synthesis and storage of various substances. Livers
D008297 Male Males
D004123 Dimethylamines Derivatives of dimethylamine (the structural formula CH3NHCH3).
D004128 Dimethylnitrosamine A nitrosamine derivative with alkylating, carcinogenic, and mutagenic properties. It causes serious liver damage and is a hepatocarcinogen in rodents. Nitrosodimethylamine,N-Nitrosodimethylamine,NDMA Nitrosodimethylamine,N Nitrosodimethylamine,Nitrosodimethylamine, NDMA
D004247 DNA A deoxyribonucleotide polymer that is the primary genetic material of all cells. Eukaryotic and prokaryotic organisms normally contain DNA in a double-stranded state, yet several important biological processes transiently involve single-stranded regions. DNA, which consists of a polysugar-phosphate backbone possessing projections of purines (adenine and guanine) and pyrimidines (thymine and cytosine), forms a double helix that is held together by hydrogen bonds between these purines and pyrimidines (adenine to thymine and guanine to cytosine).
