[Cytochemical activity of cells of the lymphocytic-macrophageal system in patients with chronic acquired toxoplasmosis].

The peripheral blood lymphocytic activities of acid phosphatase (AP) and acid nonspecific esterase (ANE) (alpha-naphthylacetate esterase) were determined in 45 patients with chronic acquired toxoplasmosis on an exacerbation. There was a considerable increase in the activity of AP in the white blood cells, which being more pronounced in the monocytes. The activity of ANE was moderately enhanced in the lymphocytes. The determination of the leukocytic activities of AP and ANE may be used as additional tests in the diagnosis of an exacerbation of chronic acquired toxoplasmosis and in the evaluation of the efficiency of the treatment performed.
