To the question of changing the blood picture in the conditions of chemical production

We set ourselves the task of establishing how the effect of ether vapors and nitrogen oxides is reflected in the hemogram during a long stay in production. For this purpose, we have carried out about 180 complete blood tests of workers at chemical plant N, of which one group of workers is exposed to ether vapors at a concentration of 5 to 20 milligrams. and more by 1 L of air, the other - to the effect of nitrogen oxides of various concentrations (the concentration ranges from thousandths of a milligram. to tenths and even up to several milligrams., 3-5, per 1 L of air).

The subjects underwent a complete blood test (from 9 to 12 am). Hb was determined with a Sahli hemometer (calibrated). Erythrocytes and leukocytes were counted in the Bürker chamber (Türk grid). The smears were stained according to Pappenheim’y (Mau-Grünwald-Giemsа), it was counted according to Sсhіlling’y not less than 200, more often 300 leukocytes. To detect basophilic granularity in erythrocytes, smears were stained according to the method proposed by E.O. Freyfeld (diluted aqueous solution of 1% methylene blue — 5 drops per 20 bar of tap water, staining within an hour). In most workers, the number of young erythrocytes-reticulocytes was determined (blood test on the substantia granulo-filamentosa); coloring according to Schilling'y — combined coloring Brillanteresylblau Giemsa; 1000 erythrocytes were counted and the number of reticulocytes encountered; in addition, their content was assessed by fields of view.
