[The mechanism of immune alteration of leukocytes].

The effect of properdin, lysozyme and complementary activity of the blood serum on the degree of immune alteration of leukocytes was revealed on the clinico-experimental material. In the leukocytolysis a neutrophil apparently serves as a mechanical substrate. It is likely that the cytophilic organic antibodies conditioned the indirect variety of leukocytolysis.

[Indicators of nonspecific immunity in cirrhosis and primary cancer of the liver].

The study of some factors of nonspecific immunity in 85 patients with cirrhosis and in 9 patients with primary cancer of the liver revealed a decrease of all factors of nonspecific immunity under consideration, while in primary cancer of the liver--selective and more sharp fall of properdin level. The complement, as compared with the control, was not changed, whereas lysozyme was statistically reliably higher than in healthy persons.
