Activity of acid and alkaline phosphatase in neutrophils of rats exposed to benzene and treated with selenium.
Cytochemical studies on activity of acid phosphatase (AcP) and alkaline phosphatase (AP) in peripheral blood neutrophils of rats chronically exposed to benzene vapours (1,200 mg/cm3) demonstrated that the exposure results in the increase of AcP and the decrease of the AP activity. The changes noted correlate with the time of exposure and are observed even after 5 months after exposure. The administration of sodium selenate in a dose of 1.0 microgram/kg before exposure prevented the above enzymatic alterations caused by benzene. In contrast, the administration of selenium in a dose of 5.0 microgram/kg only prevented the change of AP activity and caused reactive neutrophilic leukocytosis.
