摘要: 给小鼠吸入70 号汽油30d、60d、90d ,动态观察了不同剂量的汽油(250mg/ m3 、500mg/ m3 、1000mg/m3) 对小鼠骨髓细胞染色体畸变(CA) 及微核(MN) 的影响。结果小鼠吸入汽油90d ,在剂量为1000mg/ m3 的浓度下,染色体畸变率与阴性对照有非常显著差异( P < 01005) ;而小鼠骨髓嗜多染红细胞微核试验在小鼠吸入汽油60d 时高剂量下(1000mg/ m3 ) ,90d 时中剂量(500mg/ m3 ) 、高剂量(1000mg/ m3 ) 下与阴性对照有显著性差异( P < 0101 、P < 0105、P < 01005) 。表明长期慢性吸入汽油对小鼠骨髓细胞染色体有损伤作用。

Abstract: The influence of a long2term exposure to 70 gasoline on chromosomes and micronuclei in bone marrow cells of mice was investigated. The animals were exposed to 70 gasoline at low (250mg/ m3) , medial (500mg/ m3) and high (1000mg/ m3) doses for 30 、60 、90d. After exposure for 90d (at high dose/ 1000mg/ m3) , the f requency of CA was significantly higher than that in the negative cont rol group. However , after exposure of r 60d (at high dose) and 90d (at mid/ high doses) , the f requency of micronuclei in polychromatic erythrocytes was significantly higher than that in the negative cont rol group. The data suggested that chronic exposure to gasoline may be hazardous to chromosome in bone marrow cells of mice.
