[Antiradiation effects of leucynferon on dogs and guinea pigs]. / Protivoluchevaia éffektivnost' leikinferona u sobak i morskikh svinok.

In experiments with two species of animals (dogs, guinea pigs) irradiated with sublethal and lethal doses of gamma-rays, it was observed, that leucynferon had antiradiation effect. Course of injections: dogs--8 injections subcutaneus: 2.0 ml (1, 3, 5, 8, 12, 14, 21, 34 days after irradiation); guinea pigs--14 injections subcutaneus, 0.2 ml (1-14 days after irradiation). Therapeutical effect was explained by capacity of the preparation to defend the hemopoietic organs from the radiation and to stimulate hemopoiesis. Leucynferon hindered the development of acute radiation sickness symptoms. Immunoreactivity of dogs and guinea pigs in experimental group was more complete and restored faster. The growth of the automicroflora on the skin was restrained. Production of interferon-gamma (which is a function of T-lymphocytes) was restored faster.

[Efficacy of leukinferon immunocorrection in patients with maxillofacial phlegmons]. / Effektivnost' immunokorrektsii leikinferonom u bol'nykh s flegmonami cheliustno-litsevoi oblasti.

Clinical and immunological studies were carried out in patients with maxillofacial phlegmons treated by traditional methods and by traditional therapy supplemented by immunocorrection (leukinferon). Addition of leukinferon to basic therapy had a pronounced clinical and immunomodulating effect, which resulted in shorter hospitalization period and virtually complete recovery of the main immunological parameters, in contrast to traditional therapy alone. The most demonstrative parameters were the expression of the neutrophil granulocyte membrane receptors and the relationships between T-lymphocyte subpopulations, which prompted using them as the most significant diagnostic markers indicating the disease severity and treatment efficiency.

[Effects of immunomodulator leukinferon on the course of experimental tuberculosis]. / Vliianie immunomoduliatora leikinferona na techenie éksperimental'nogo tuberkuleza.

An experiment was conducted on 60 CBA mice intravenously inoculated with cultured Mycobacteria tuberculosis (MBT), Erdmann strain, in a dose of 0.025 mg. The specific features of tissue, cellular, and biochemical reactions were studied in the lung, liver, and spleen when leukinferon (LF) was included into tuberculosis treatment regimen. LF was shown to have a positive impact on the development of reparative reactions during tuberculous inflammation by reducing the time of abacillation and recovering the structure of diseased organs. By month 3 of follow-up, MBT were not detected in mice receiving antibacterial agents (ABA) and LF, while typical and changed forms of LF were identified in the cytoplasm of alveolar macrophages in mice treated with ABA alone. A specific feature of an inflammatory reaction as a significant proliferation of lymphocytes and macrophages with their ample infiltration of target organs was noted in animals receiving LF. This was followed by the activated production of alpha- and gamma-interferons and by the mobilization of an enzymatic link of anti-oxidant defense under chronic oxidative stress, which led to a reduction of resolution of inflammatory areas and to an increase in survival of animals which had not been given ABA, but treated with LF alone.

[Leukinferon in the treatment of patients with sepsis and multiple organ dysfunction syndrome]. / Leikinferon v lechenii septicheskikh bol'nykh s sindromom poliorgannoi nedostatochnosti.

Dynamics of clinical signs, blood formula and some cytokins in serum samples of the patients with sepsis complicated by multiorgan disfunction syndrome (as a rule kidney and liver were involved) were investigated. Etiotropic therapy was combined with immunocorrecting treatment with leukinferone Combined regime provided positive results in clinical symptoms, in lymphocytes number normalization (abs. and per cent), stimulated T lymphocytes differentiation and facilitated intoxication finishing according to LII). Immunocorrection practically had no effect on TNF-alpha, IL-1 alpha, IL-6, and stimulated IL-8 secretion more effectively than etiotropic therapy. IF-gamma level enhanced along with stopped IL-10 production. As a result ratio of IF-gamma/IL-10 enhanced from 0.56 to 1.0, in the case of etiotropic therapy this ratio diminished from 0.48 to 0.3. It is concluded that immunocorrecting therapy provided positive dynamics in the ration IF-gamma/IL-10, recurring cell immune reactions. The recurrence period was shortened and lethality level was substantially lower (2.5 times).

[Efficiency of immunocorrection using cytokines in the therapy of papillomavirus infection]. / Effektivnost' immunokorrektsii tsitokinami pri lechenii papillomavirusnoi infektsii.

The data of the immunological examination and the results of treatment of 86 patients with papillomavirus infection (PVI) are presented. The multifactor suppression of cell-mediated and humoral immunity was established. The degree of immune disturbances correlated with the spread and severity of lesions. The use of systemic injections of cytokines (leukinferon and concentrated interferon) in low doses as adjuvant therapy with laser-radiosurgery led to the normalization of most immunological characteristics and the course of PVI without relapses.

[Expression of receptors for human alpha- and gamma-interferons on the surface of peripheral blood mononuclear cells in viral infections]. / Ekspressiia retseptorov dlia chelovecheskikh alpha- i gamma-interferonov na poverkhnosti mononuklearnykh kletok perifericheskoi krovi pri virusnykh infektsiiakh.

Expression of receptors on peripheral blood mononuclears of donors and patients with viral infections during therapy was studied using FITC-labeled monoclonal antiidiotypical antibodies with the "internal image" of human alpha- and gamma-interferons and monoclonal antibodies to these interferons. Activation of the immune system caused by infection modifies the expression of interferon receptors and leads to appearance of membrane-bound interferons, mainly gamma-interferon.

[Therapeutic antiradiation properties of leukinferon]. / Protivoluchevye terapevticheskie svoistva leikinferona,

In experiments with three species of animals (mice, rabbits, monkeys) irradiated with sublethal and lethal doses of gamma-irradiation, it was observed, that leukinferon used in 4 hours or 10 days after provided antiradiation therapeutical effect. When lethal dose was used (mice) the survival of animals was significantly increased. The preparation decreased depression of the functional activity of leukocytes as it was observed with IFH-alpha and gamma-production. Pestoring this function was accelerated. Phenomena pancytopenia and thrombocytopenia induced by radiation were decreased. Therapeutical effect was explained with capacity of the preparation to defence the hemopoietic organs from the radiation and to stimulate hematopoiesis. So, spleen weights and quantity of cells into bone marrow were higher in experimental group in comparison with control at any observation. CFUs were also higher (with optimal dose of preparation). Stimulation of the restoring processes was confirmed also by more intensive increasing of the reticulocyte quantities in the circulation of experimental monkeys within 20 days. Then their level became more close in both groups. The preparation stimulated also differentiation of immune effectors: immature neutrophils were absent in the circulation of experimental monkeys. Production of IFN-gamma (which is function of T-lymphocytes) was restored more fast. As a result, immunoreactivity of monkeys in experimental group was more complete and restored faster: the growth of the automicroflora on the skin surface became to increase 7 days later and was restrained. Leukinferon hindered the development of acute radiation sickness symptoms.

[Protective action of leukinferin during radiotherapy of oncologic patients]. / Zashchitnoe deistvie leikinferona pri luchevom lechenii onkologicheskikh bol'nykh.

In clinical observation on 248 patients with breast cancer IIb-III-b stages given radiotherapy on breast gland, parasternal and axillary-subclavian regions (total doses 40 Gr for each) before mastectomy was shown, that use LF im 2-3 times a week through the course of therapy decreases statistically significant pancytopenia, induced by radiation. Quantity leukocytes was even increase in a process of therapy. Frequency of anemia and lyphopenia was decreased almost 3 times. E-RFC were depressed also more slight, then in the group without immunocorrection and after mastectomy practically, restored. IFN-gamma production by T-lymphocytes was not changed and essentially more high then in the comparative group. The presented data are shown, that LF provides a defensive action on hematological indices and immune effectors function in oncological patients during radiotherapy.

[The clinico-immunological effects of leukinferon in the treatment of patients with acute suppurative pyelonephritis]. / Kliniko-immunologicheskie éffekty leikinferona pri lechenii bol'nykh s ostrym gnoinym pielonefritom.

A many as 20 patients with acute purulent pyelonephritis were studied for clinical and immunological effects of leukinferone. The above patients were convalescent earlier than control subjects. There were instances where clinical status was not accompanied by shifts in immunity. However, on an average in the group, such parameters as level of lymphocytes, amounts of B-cells, Igs G, A, T-helpers, and Tx/Tc ratio were found to be increased as was activity of EK-cells. Stimulating effects of leukinferone were particularly pronounced in those patients with decreased values for immunological status. A conclusion is reached to the effect that patients with acute pyelonephritis may benefit from those treatments involving the use of the above drug preparation.

[The characteristics of the immune response in acute viral hepatitis B]. / Nekotorye osobennosti immunnogo otveta pri ostrom virusnom gepatite B.

The clinical and pathogenetic importance of a number of features characterizing cell-mediated immunity and nonspecific protective factors in acute virus hepatitis B. 124 patients with hepatitis B virus (HBV) infection were placed under observation. Of these, 115 patients had acute virus hepatitis B, 6 patients had acute virus hepatitis of mixed etiology (B + delta) and 3 patients had chronic virus hepatitis B. The study included, besides the detection of virus hepatitis markers and the biochemical analysis of blood, the determination of subpopulations of peripheral blood lymphocytes (CD3, CD4, CD8, CD57), the functional activity of natural killers, characteristics of the interferon status, serum neopterin and beta 2-microglobulin in blood serum. Considerable changes in cell-mediated immunity and the interferon system were found to occur and the optimum immune response in acute virus hepatitis B was characterized.

[The clinical efficacy in using leukinferon in adults with diseases caused by the varicella-zoster virus]. / Klinicheskaia éffektivnost' primeneniia leiinferona u vzroslykh pri zabolevaniiakh, vyzvannykh virusom vetrianoi ospy.

To achieve more effective treatment of varicella (chickenpox) and herpes zoster in adults, a wide-spectrum immunocorrective agent containing, together with alpha-interferon, a number of other cytokines of the first phase of immune response was used. In patients with the different severity of disease leukinferon induced a rapid decrease in the severity of the disease, arrested the development of new elements on the skin and the buccal mucosa, and reduced the duration of the fever period. When used in such forms as intramuscular injections in combination with the irrigation of the buccal mucosa and ointment, leukinferon proved to be a highly effective preparation for the treatment of diseases caused by varicella-zoster virus.

The paper presents a technical, medical and economic rationales for the expediency of simultaneous manufacture of three models of present-day test spectacle frames, such as general-purpose, semiframe, and simplified semiframe ones, which will provide their rational, methodological and the most efficient use in choosing corrective spectacles in relation to the complexity of chosen vision correction.

[The use of leukinferon in treating measles in adult patients]. / Primenenie leikinferona pri lechenii kori u vzroslykh bol'nykh.

The following mucosal are characteristic of measles in adult patients: dryness in the oral cavity, dryness, desquamation, and fissures in the red edge and in the mouth corners, edema and hyperemia, of the buccal mucosa, macular enanthema on the hard and soft palate, Bel'skii-Filatov-Koplik spots, whitish deposit on the gingiva, edematous and bleeding gingiva, and, as a result of general intoxication, a lingual deposit. Leukinferon, a wide-spectrum immunocorrective drug, was used to improve the efficacy of treatment of adult patients with measles; besides alpha-interferon, it contains other cytokines of the first phase of immune response. Therapy with leukinferon led to a sooner improvement of the general status and a more rapid regression of the disease symptoms, including changes in the buccal mucosa, in comparison with the control leukinferon-untreated group.
