[Immunomodulators of microbial origin enhance cytotoxicity of human mononuclear leukocytes and reduce metastatic progression of Lewis lung carcinoma in mice].

Effect of immunomodulators for microbial origin on innate immunity and antitumor system was continued to study. Immunomodificator Immunovac VP-4, purified staphylococcal toxoid and glucosaminyl muramyl dipeptide (GMDP) equally enhanced cytotoxicity of mononuclear leukocytes of peripheral blood of healthy donors. Index of cytotoxicity was 2.78, 2.77 and 2.70 respectively. Reduced metastatic progression of Lewis lung carcinoma in mice was observed after Immunovac VP-4 and GMDP administration. Effectiveness was seen when preparations administered according to schedules including their administration before implantation of the tumor. If preparations were administered number of metastases reduced in 4.4-5.6 times and size of metastases reduced in 7-10 times. Interplay between antitumor activity of studied immunomodulators and cytotoxic activity of NK-cells, which are base effectors of antitumor immune response, are discussed.

[The mechanisms of the impact of preliminary immunization with staphylococcus anatoxin on postresuscitation pathology of the myocardium].

Chronic experiments lasting for 5 weeks were carried out in 40 nonpedigree mature dogs. It has been detected that preliminary immunization with staphylococcus anatoxin potentiates the compensation mechanisms in the course of postresuscitation period, stimulates cell proliferation by increasing cardiac output that is an adaptive reaction of the cardiovascular system in postresuscitation period and provides optimal metabolism of the organism.

[Clinical and immunological changes in atopic dermatitis patients treated with purified staphylococcal toxoid]. / Klinicheskie i immunologicheskie izmeneniia u bolnykh atopicheskim dermatitom pri terapii anatoksinom stafilokokkovym ochishchennym.

32 patients with atopic dermatitis (AD), complicated by pyoderma, were treated with purified staphylococcal toxoid (PST). Changes in clinical and laboratory characteristics in the course of treatment were evaluated. PST was shown to produce a satisfactory therapeutic effect, arresting the symptoms of local staphylococcal infection. An increase in the levels of alpha- and gamma-interferons and decreased content of CD25+ lymphocytes were found. Thus prospects appear for using this preparation as an interferon inductor, as well a for the immunotherapy of AD patients sensitized to Staphylococcus aureus.

[The correction of immunity in adolescents and children with focal staphylococcal diseases]. / Korektsiia imunitetu u pidlitkiv i ditei z vohnyshchevymy stafilokokovymy zakhvoriuvanniamy.

The aim of the work done was to improve treatment options for focal Staphylococcus-induced diseases in adolescents and children with the aid of adsorbed staphylococcal anatoxin (ASA) concurrently with low-intensive EHF therapy. Overall fifty patients aged 3 to 17 years with Staphylococcus infection in tonsils, nose, ears were kept under medical surveillance. ASA and EHF therapies were instituted according to the developed schemes of such therapies. Positive dynamics was shown of clinical picture and parameters characterizing humoral and cell-mediated immunity. There were no unfavourable side-effects. The proposed mode of treatment can, we believe, be widely used in a clinical setting.

[An immunomodifier--staphylococcal anatoxin--prevents the development of immunosuppression caused by informational stress in mice]. / Immunomodifikator--stafilokokkovyi anatoksin--preduprezhdaet razvitie immunosupressii, vyzvannoi informatsionnym stressom u myshei.

The action of information stress for 14 days leads to the development of immunosuppression, which is manifested by the suppression of humoral response to sheep red blood cells (SRBC) and the decrease of resistance to Langat virus having low pathogenicity. As shown in this investigation, an immunomodifier, purified staphylococcal toxoid (PST), protects experimental animals from the immunosuppressive effect of information stress. After the injection of PST to stress-affected mice in doses of 15 or 1.5 binding units per animal on days 9, 11 and 13 of the experiment their humoral response to SRBC and resistance to Langat virus are partially restored (by 45-60%).

[An experimental validation of immunotherapy with purified staphylococcal anatoxin]. / Eksperimental'noe obosnovanie immunoterapii anatoksinom stafilokokkovym ochishchennym.

Inbred mice have proved to be a promising model for the evaluation of antigen-specific and antigen-nonspecific immunomodulating activity of purified staphylococcal toxoid in humans. This toxoid induces the formation of pronounced humoral response to homologous and heterologous infections in humans and mice. In animal experiments purified staphylococcal toxoid has shown its capacity for the correction of secondary immune deficiency of different origin; when introduced into humans having secondary immunodeficiency associated with bacterial infections of different etiology, the preparation reproduces this effect.

[The capacity of purified staphylococcal anatoxin to correct antigen-specific and antigen-nonspecific immunological defects]. / Sposobnost' anatoksina stafilokokkovogo ochishchennogo ispravliat' antigenspetsificheskii i antigennespetsificheskii immunologicheskie defekty.

Purified staphylococcal toxoid is capable of partially preventing the development of antigen-specific (induced by the supraoptimal dose of sheep red blood cells) and antigen-nonspecific (induced by Tahyna virus) defects of humoral immune response, as well as abolishing these defects. The presence and manifestation of the correction of virus-induced immunodeficiency is determined by the dose of the toxoid and the interval between the injections of purified staphylococcal toxoid and the infective agent.

[A complex vaccine in the prevention of staphylococcal, Pseudomonas aeruginosa and Proteus infections in esophageal cancer patients]. / Kompleksnaia vaktsina v profilaktike stafilokokkovoi, sinegnoinoi i proteinoi infektsii u bol'nykh rakom pishchevoda.

An analysis of clinico-immunological data has demonstrated a considerable decline in non-specific and specific defences against such major factors of hospital infection in esophageal cancer patients as staphylococcal, blue pus and Proteus bacilli. Immunization with a complex vaccine including concentrated staphylococcal anatoxin, blue pus and Proteus vaccines was shown to stimulate the said factors of anti-infectious immunity and to be followed by a 4.7-fold decrease in the incidence of postoperative pyo-inflammatory complications. The said vaccine may be recommended for prevention of infectious complications in cancer patients since its administration is followed by a low-level reaction matched by a marked increase in immunologic vigor.
