苯是工业生产中广泛使用的一种有机溶剂,慢性苯中毒是危害工人健康较为产重的职业病之一。慢性苯中毒主要影响造血系统,白细胞减少常视为早期诊断客观指标之一。不少作者指出白细胞数量改变时质量也发生改变,且比数量改变出现得早,本文目的,是用细胞组织化学和形态学方法,摸索苯接触者的周围血液变化规律作为早期诊断寻 Benzene is an organic solvent widely used in industrial production. Chronic benzene poisoning is one of the occupational diseases that endanger the health of workers. Chronic benzene poisoning mainly affects the hematopoietic system, leukopenia often considered as one of the early indicators of objective diagnosis. Many authors pointed out that when the number of leukocytes changed, the quality also changed, and earlier than the change in the quantity appeared. The purpose of this paper is to use cell histochemistry and morphological methods to explore the changes of peripheral blood in benzene-exposed patients as an early diagnostic search
