[Assessment of blood lymphocyte subpopulations by the immunoenzyme cytochemical PAP method using different fixatives].

The method of fixation of cytologic material was modified for a relatively safe immunocytochemical staining with para-aminophenasine (PAPh) in order to provide the intactness of the principal differentiation antigens of lymphocytic surface membranes of human peripheral blood. The method is recommended for practical studies of immunophenotypic lymphocyte subpopulations in HIV-infected subjects and patients with AIDS and other infectious diseases.

[The antioxidant treatment of patients with acute intestinal infections due to gram-negative microorganisms].

It was established that administration of S. typhimurium lysate causes activation of the processes of free-radical oxidation. Introduction of unithiol in combination with magnesium sulfate returns the intensity of these processes to the initial level.

[Changes in the complement system in acute streptococcal infection].

Results are reported of a study of relationship of complement level, unspecific adaptative reactions, number of circulating immune complexes and some cellular parameters of the immunogram in patients with different forms of streptococcal infection. Different changes were found in acute and chronic forms of the disease. The possible mechanisms of development of these disorders are discussed.

[Protective effect of unithiol and its combination with magnesium sulfate in endotoxin poisoning and in infection by gram-negative bacteria].

It is shown that unithiol protects mice from death in intoxication by S. typhimurium and S. Sonnei lysates and in infection caused by S.

[Secondary immunopathology in patients with an acute streptococcal infection].

The authors studied the activity of complement, nonspecific adaptive reactions of the body, the presence of antibodies to cross-reacting antigens of Streptococcus, the concentration of circulating immune complexes, some cellular characteristics of the immunogram in patients with different forms of streptococcal infection. The changes revealed allow a conclusion about the presence of autoimmune processes, most pronounced in chronic and recurrent forms of diseases. In the formation of streptococcal infection relapses, of the role is pathology of the complement system in combination with disorders in other components of nonspecific anti-infection resistance.
