早在1958年程元恺报道焦油工人血象白细胞减少以来,我所自1965年起对本公司焦化厂接触焦油的职工体检中亦发现有白细胞减少者,并发现随着工龄的增长,白细胞减少者越来越多。迄今接触焦油可致白细胞减少症,逐渐受到重视,但尚无焦油混合物中毒的诊断标准。本文根据焦油作业工人五年以上的接触史,有神衰症候群,白细胞计数连续检查3次均在4000个/mm~3以下,并经住院观察三天,检查6次仍低于4000个/mm~3以下,能排除其它原因所致白细胞减少者,自1975年以来先后诊断了40名焦油职工白细胞减少症。
As early as 1958, Cheng Kai-kai reported tar workers leukopenia since, I since 1965, the company coking plant workers contact with tar workers also found leukopenia, and found that as the length of service, leukopenia are more and more many. So far, contact with tar can cause leukopenia, and gradually receive attention, but there is no diagnostic criteria of tar mixture poisoning. According to the contact history of workers with tar working for more than five years, there are 4 cases with the symptoms of Shenyin Syndrome, the number of white blood cell count being less than 4,000 / mm ~ 3 and the number of hospital stay after 3 days. ~ 3 following, to exclude other causes of leukopenia, since 1975 has diagnosed 40 workers tar workers leukopenia.
