Abstract |
A series of in vitro experiments were conducted to determine if there are innate differences in the sensitivity of peripheral blood lymphocytes (PBLs) from different mammalian species to clastogens. Mouse, rat, and human whole blood samples were exposed to either 0, 0.38, 0.75, 1.5, or 3.0 Gy x-radiation or 0, 5, 10, 20, 40, or 80 micrograms/ml bleomycin for 4 h. Bromodeoxyuridine-containing cultures were initiated and the PBLs stimulated to divide with phytohemagglutinin. All cultures were harvested following a 3-h colcemid treatment. Slides were made and differentially stained, and first-division metaphases were scored for chromosome aberrations. In the x-radiation studies human PBLs were significantly more sensitive than mouse PBLs which were in turn more sensitive than rat PBLs as measured by either the total percent aberrant cells or the number of dicentrics. Results with bleomycin suggest that the mouse and human PBLs are equally sensitive to the clastogenic effects of bleomycin. These results indicate that there may be inherent differences in sensitivity among PBLs of mammalian species; however, more studies are needed to determine if the differences presented here hold for other agents. |
