[The effect of leukinferon on the activity of phagocytosing cells in human salmonellosis].

The functional activity of phagocytic cells in 52 salmonellosis patients was studied with regard to the following characteristics: percent share of phagocytosis, phagocytic index, nitro blue tetrazolium test results, digestive activity. In patients with the unfavorable course of salmonellosis (the formation of carrier state) disturbances in the bactericidal activity of neutrophils and monocytes were established. For 32 patients leukinferon was included in the complex of etiotropic and pathogenetic treatment. The preparation was introduced in 3 intramuscular injections of 10,000 I. U. at intervals of 48 hours (the course of treatment); 10 days after the last injection this course was repeated. The use of leukinferon restored the normal functioning of phagocytes and the number of T-lymphocytes.

[The effect of interferon preparations on the ultrastructural organization of Legionella pneumophila].

The influence of the preparations of interferon on morphological changes in L. pneumophila on the ultrastructural level has been studied. Disturbances in the ultrastructure of L. pneumophila result from the direct bactericidal action of interferons without any interference of immune mechanisms. These disturbances are manifested by damages in the cell wall, plasma membrane, nuclear and ribosomal apparatuses of microbial cells. Leukinferon exhibits pronounced anti-Legionella activity, both in vitro in a liquid culture medium and in ovo, than reaferon.

[The treatment of different forms of B and delta hepatitis with interferon preparations].

A study was made of the therapeutic efficacy of human leukocytic interferon (HLI) and leikinferon in the treatment of HBV- and HDV-infection. 21 patients were placed under observation. Of these, 6 presented with lingering hepatitis B (HB), 8 with chronic HB, 1 was a HBsAg carrier, 4 had Grades I-IV, acute hepatic encephalopathy, and 2 acute hepatitis delta. 15 patients received leikinferon, 6 were given HLI for injections. Indications and schemes for the treatment with interferon preparations are provided as are the clinico-biochemical and serological criteria for estimating the efficacy of interferon therapy. In lingering and chronic forms of HB, leikinferon exerts a beneficial effect. It is not costly, thus enabling one to carry out continuous treatment in patients suffering from chronic forms. HLI may be recommended as an effective agent.

[Functional activity of platelets in preterm labor].

The platelet component of the hemostasis system was studied in women during preterm labor; platelet functional activity was correlated to changes in prostaglandins E and F-alpha, prostacyclin and thromboxane A2 concentrations. Preterm labor is associated with a significant elevation of platelet functional activity, compatible with that in timely labor. A marked elevation of blood prostaglandin levels was detected. The authors claim that elevated platelet functional activity results not from a gradual increase of the hemostatic potential, but from systemic effect of the labor activity trigger mechanisms on blood coagulation cellular mechanism.

[Highly active interferon in the combined treatment of patients with meningoencephalitis].

High-active interferon was used in the complex treatment of 49 patients with nervous system diseases of viral-bacterial etiology. A control group of 28 similar patients were also analyzed. A positive clinical effect was observed in early use of interferon. The clinical course of the disease was milder, the duration of clinical symptoms reduced, healing of the CSF was enhanced, the development of protracted forms of the disease was preventable, lethality reduced 2.9 times with interferon in the complex treatment of these patients.

[Gallstone-induced intestinal obstruction].

Six patients with gallstone ileus were under observation. The diagnosis was not established before the operation. Surgery was undertaken for acute ileus without identification of the cause. Stones in the intestinal lumen were an unexpected operative finding. The operation of choice was a minimal intervention for the restoration of intestinal continuity (enterolithotomy, resection of the intestine whenever necessary). Five patients recovered, one died.

[Immunomodulating properties of leukinferon].

Tolerance and immunomodulating properties of leukinferon for injections were studied in 13 healthy volunteers. The drug was administered by inhalation and intramuscularly in a single dose of 10,000 MU twice daily for 3 days. Intramuscular injections of the drug were accompanied by a number of side effects: pyrogenicity, weakness, headache, that ceased 8-12 hrs after the drug was discontinued. Despite these side effects, the drug was satisfactorily tolerated. Neither viscera nor systemic disorders nor allergic reactions were detected. T-lymphocytes proved to be the most sensitive to the drug. Leukinferon was found to activate the interferon system. The effect was the most marked in respect of IRL-gamma.

[The immunomodulating action of interferon preparations. The effect of medicinal alpha-interferon preparations on the rosette-forming activity of human blood lymphocytes].

Effects of alpha-interferon (alpha-IF) medical preparations on human blood lymphocyte rosette-forming activity was under study. Blood samples from 40 donors and 81 patients with chronic pyoderma, lupus erythematosus, and pemphigus were examined. Interferon preparations alpha-IF for nasal administration and IN-1 and IN-2 (or leukinterferon) for injections were used. The results evidence that IF preparations activities depend on the methods of the preparation synthesis and purification. alpha-IF and leukinterferon most effectively enhanced the lymphocyte ability to spontaneous, early, and active rosette formation. IN-1 was found less active and enhanced only the ability to spontaneous E-rosette formation, but had no effect on early active E-RFC subpopulations. IF preparations elevated the counts of E-RFC anf active RFC only if these levels were lowered; if these values were normal the agents had no effect.

[Clinical and laboratory effect of leukinferon in purulent infections].

Clinical trials of human leukocytic alpha-interferon for injections, leukinferon were performed in 51 patients with different forms of surgical purulent infections. It was shown that leukinferon lowered the terms of normalization of body's temperature, leukocytosis, respiratory neutrophilic outbreak and levels of active T-lymphocytes. The same was observed when leukinferon was used prophylactically in cardiosurgical patients. The effect of leukinferon depended on the level of radical operations on primary purulent foci and severity of the patient's state. Leukinferon had immunomodulatory properties and mainly influenced the system of neutrophilic phagocytes. The action was lymphocyte-mediated. The rapid effect of leukinferon makes it necessary to recommend it for treatment of patients with purulent infections as an agent of urgent immunomodulation.

[The effect of injectable leukinferon on the immune reactivity of patients with steroid-dependent bronchial asthma].

The authors provide the results of the treatment with leukinferon for injections of 25 patients with steroid-dependent bronchial asthma. It is the authors' belief that leukinferon for injections may be recommended for introduction into multimodality schedules of the treatment of patients with the above-indicated pathology. The drug is tolerated well, without any phenomena of sensitization, when administered by inhalation in the form of aqueous aerosol in a dose of 10,000 IU/day. As a result of 6 to 8 injections, immunoreactivity showed a positive time-course of changes, the patients' clinical status improved, and the maintenance doses of glucocorticosteroids could be noticeably reduced.

[Results of the use of human leukocytic interferon in the treatment program in acute lymphoblastic leukemia in children].

Soviet preparation of human leucocytic interferon (HLI) was injected to 112 children with acute lymphoblastic leukemia at different stages of the treatment program. The results obtained have evidenced that HLI produces a direct antitumor effect, intensifies the effectiveness of inductive chemotherapy and the treatment program leading to the prolongation of the remission period and survival of the patients, as well as induces activation of natural and antitumor resistance of the body.
