本文报告在光镜和电镜下,慢性苯中毒大鼠外周血和骨髓血细胞形态学改变,为探讨慢性苯中毒的诊断提供细胞形态学资料。 材料和方法 实验用成年正常大鼠44只。实验组23只,每天静式染毒4小时,每周6天,共115天。实验组大鼠染毒前白细胞数为14,300个/立方毫米,染毒结束时为5,450个/立方毫米。对照组白细胞数为15,720个/立方毫米。苯蒸气平均浓度为11.48克/立方米。
This paper reports the morphological changes of blood cells and bone marrow cells in chronic benzene poisoning rats under light microscope and electron microscope, and provides cell morphological data for the diagnosis of chronic benzene poisoning. Materials and Methods 44 adult normal rats were used. Experimental group of 23, the daily exposure to four hours a day, six days a week for a total of 115 days. The number of leukocytes in the experimental group was 14,300 cells / mm3 before treatment and 5,450 cells / mm3 at the end of the exposure time. The number of white blood cells in the control group was 15,720 cells / mm3. The average benzene vapor concentration was 11.48 grams per cubic meter.
