Abstract
We examined the effects of administration of (E) 4-[4-N,N-dimethylaminophenyl]but-3-en-2-one (DMAP) on radiation-induced chromosome damage in mice. Mice were whole-body exposed to γ-rays, 0-4 Gy, and then immediately administered DMAP, 20 mg/kg. After 24 h, mice were sacrificed, femora were removed, marrow was extracted, and chromosome aberrations were scored in the bone marrow cells. With vehicle-only (saline or oil) treatment, radiation dose-dependent damage was seen in aberrant cells, chromosome breaks, chromatid breaks, centric rings, di-, tri-, and tetracentrics, acentric fragments, total aberrations, polyploidy, and pulverization. Post-administration of DMAP was protective as it reduced chromosome damage. DMAP treatment may be a useful protective agent following radiation accidents or radiotherapy.
