For a long time some pesticides (chlordane, lindane, DDT) have been associated with bone marrow aplasia. Little is known on the toxic activity of the herbicides s-triazines on hemopoiesis. We studied the effect of one of these compounds (atrazine) on mouse hemopoietic progenitors (CFU-S and GM-CFC) and on peripheral blood (leukocytes and reticulocytes) after a single i.p. injection of 58.65 mg/kg. The peripheral blood leukocyte level was not modified; on the contrary, reticulocytes dropped severely but recovered promptly. Hemopoietic progenitors were severely hit but they recovered and reached normal levels in a few days. Our results demonstrate a hemotoxic effect of atrazine. However, more data are needed, especially in experiments with chronic exposure.
长期以来,某些农药(氯丹、林丹、滴滴涕)一直与骨髓再生障碍有关。关于除草剂 s-三嗪对造血作用的毒性活性,人们了解甚少。我们研究了其中一种化合物(莠去津)在单次腹腔注射 58.65 mg/kg 后对小鼠造血祖细胞(CFU-S 和 GM-CFC)以及外周血(白细胞和网织红细胞)的影响。外周血白细胞水平未发生改变;相反,网织红细胞严重下降,但很快恢复。造血祖细胞受到严重打击,但在几天内恢复并达到正常水平。我们的结果证明了莠去津的血液毒性作用。然而,还需要更多数据,尤其是在慢性暴露实验中。
