[Influence of some activators and inhibitors of alkaline phosphatase activity in the leukocytes of farm animals].

The incubation of blood smears taken from cattle, sheep, goats horses, and pigs in the presence of urea, metal salts (zinc, magnesium, manganese, calcium) or amino acids (phenilalanine, alanine, glycine, histidine, methionine, cystine cysteine) at various concentrations revealed that the cytochemical activity of the alkaline phosphatase shows changes that depended on the animal species. Changes varying in character and intensity and depending on the molar concentrations of the agents used, were also established.
