Cell proliferation in rat kidney induced by 1,2-dibromoethane. 1987

G M Ledda-Columbano, and A Columbano, and P Coni, and M Curto, and G Faa, and P Pani

The effect of a single intragastric injection of 1,2-dibromoethane was investigated in kidneys of male Wistar rats. DNA synthesis as measured by the incorporation of tritiated thymidine was found to be approximately 5 times greater than that of controls 20-30 h after treatment. DNA synthesis was followed by a striking increase in the mitotic activity with a maximum at 30 h. The labeling and mitotic activities, after an initial increase, fell rapidly 48 h after treatment even though they were still higher than those of control animals. 1,2-Dibromoethane-induced cell proliferation is not a regenerative response because at the dose used in this study, no tubular necrosis was observed by histologic examination.

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).

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D015946 Ethylene Dibromide An effective soil fumigant, insecticide, and nematocide. In humans, it causes severe burning of skin and irritation of the eyes and respiratory tract. Prolonged inhalation may cause liver necrosis. It is also used in gasoline. Members of this group have caused liver and lung cancers in rodents. According to the Fourth Annual Report on Carcinogens (NTP 85-002, 1985), 1,2-dibromoethane may reasonably be anticipated to be a carcinogen. 1,2-Dibromoethane,Dowfume W 85,Dowfume W85,Ethylene Bromide,Ethylene Dibromides,sym-Dibromoethane,1,2 Dibromoethane,Bromide, Ethylene,Dibromide, Ethylene,Dibromides, Ethylene,sym Dibromoethane
