[Effect of vibration and noise on various morphotic elements in the peripheral blood of exposed workers]

The authors examined blood cell count in 198 males and 53 females occupationally exposed to vibration and noise surpassing allowable standards. In addition, in some subjects cytochemical examinations of leukocytes were performed. Decreased amounts of erythrocytes and hemoglobin content were found. Cytochemical examinations showed an increased activity of non-specific esterase, increase PAS reaction, decreased activity of acid phosphatase, and the tendency to decrease the activity of base phosphatase.
