[Protective effect of a commercial vaccine, poludan and their combinations in an experimental herpes infection].
The antiviral action of herpes vaccine and poludan, an interferon-inducing agent, has been studied in experimental herpes infection, and the synergic effect of these preparations has been obtained. The best result (survival rate equal to 100% after the intraperitoneal inoculation of herpes simplex virus and 85.7% after its intracerebral inoculation) has been registered after the multiple vaccination of experimental animals and the injection of poludan 1 day before the challenge of the animals with the virus. The protective effect of the synergic action of the preparations under study coincides with the period of the maximum content of antibodies in the blood sera of the animals.

[Development of a suppository form of the interferon inducer poludan and potentiation of its action by hyaluronic acid].
A promising dosage form of interferon inductor poludan has been developed for the treatment of patients with genital herpes and ophthalmic herpes: suppositoria. High interferon-producing and antiviral activity of poludan in suppositoria is potentiated by hyaluronic acid and antioxidants.
[Mechanisms for the therapeutic effect of herpes polyvaccines in chronic ophthalmic herpes and genital herpes].
Commercial inactivated culture polyvaccine against herpes simplex viruses (types 1 and 2) developed at D. I. Ivanovsky Institute of Virology promoted cessation of viremia. During the first vaccination viremia coincided with appearance of a focal allergic test on the retina, which is proposed for the diagnosis of herpetic involvement of the posterior compartment of the eye. T-cellular immunity normalized after a course of vaccination. Experimental immunization of rats and vaccination of patients with chronic ophthalmic and genital herpes demonstrated the therapeutic activity of inactivated herpetic polyvaccine in suppositoria.
[The detection of the herpes simplex virus 1 and 2 antigens in clinical specimens by using monoclonal antibodies].
The possibility of using monoclonal antibodies (McAb), obtained earlier, for the detection of herpes simplex virus (HSV) in clinical specimens taken from sick and infected persons was studied. The examination of 90 persons revealed that the mixture of McAb 4A and 2C could effectively detect the presence of HSV antigen in the indirect immunofluorescence assay (IFA) directly in cells contained in cytological preparations (smears, scrapes, impressions) obtained from different organs of patients. The search of optimum combinations of McAb for the detection of HSV antigens by the method of the solid-phase enzyme immunoassay (EIA) was carried out. This study, made on purified HSV used as an experimental model, revealed that the maximum sensitivity could be achieved with the use of two McAb (4f6 and 7c4) out of three McAb (4f6, 7c4 and 3d10). The approbation of both variants of EIA on clinical specimens taken from 99 patients (blood clots, seminal fluid, scrapes of cervical canal cells, peripheral blood lymphocytes) showed that the addition of McAb 3d10 made it possible to detect 8 more positive specimens. 754 specimens from 337 patients were studied with the use of McAb-based EIA, and in 204 of these patients (61%) HSV antigen was detected. The results obtained with the use of our McAb were compared with the data obtained with certified commercial test systems. The coincidence of the EIA data with those obtained with the use of the Murex Wellcozyme HSV test system (UK) was registered in 75% of cases (in 15 out of 20 cases). The coincidence of the IFA data with those obtained with the use of the Sanofi test system (France) was observed in all 19 cases (100%).

[Indices of lymphocyte functional activity in patients with recurrent cutaneous-genital herpes during treatment with a herpes vaccine].
The functional activity of lymphocytes of patients with severe forms of recurrent cutaneous-genital herpes was studied in the course of treatment with inactivated polyvalent herpes vaccine on the basis of lymphocyte blast-transformation response to polyclonal mitogens and herpes simplex virus antigen. In the group of patients who showed a marked therapeutic effect as a result of the treatment the initially high values of the antigen-dependent lymphocyte blast-transformation test declined and became normal. Thus, in some cases the herpes vaccine exerts an immunomodulating effect normalizing the functions of different lymphocyte subpopulations.
[Use of a conjugate of staphylococcal protein A with peroxidase in an immunoenzyme test system for determining antibodies to the herpes simplex virus].
An enzyme-immunoassay system for the detection of specific antibody to herpes simplex virus was developed in which the antigen layered on the solid phase consisted of a crude extract of infected cells, and the detecting agent was a conjugate of protein A with horseradish peroxidase. This assay system was used for serological examination of 22 serum specimens from patients suffering from either meningoencephalitis or recurrent herpes of the skin and mucous membranes of the genitalia, as well as 6 specimens of the cerebrospinal fluid from patients with meningoencephalitis. The enzymeimmunoassay was found to be more sensitive than CFT. The advantages of using protein A/peroxidase conjugate for rapid estimation of the total amount of specific antibodies at any stage of herpes infection are discussed.
[Indices of the immune status of recurrent herpes patients being treated with a herpes polyvaccine].
Patients with dermal and genital forms of recurring herpes were found to have decreased levels of leukocytes and changed balance of the peripheral blood lymphocyte populations. Treatment with herpes inactivated cultural polyvaccine produced a therapeutic effect in a significant number of patients which was accompanied by a correcting effect of the vaccine on their immune status.
[Viral antigens in kidney biopsies of children with glomerulonephritis].
A relationship between clinical forms of glomerulonephritis and incidence of viral antigens in renal tissue was revealed: Hepatitis B virus antigens (HBsAg) are more frequently detected in the glomeruli in the patients with nephrotic glomerulonephritis, Herpes simplex antigens are detected in the glomeruli in mixed glomerulonephritis, and cytomegaloviral and Herpes simplex antigens are detected in the epithelium of the proximal canaliculi in patients with hematuric glomerulonephritis. No correlations between the persistence of Herpes simplex type 1, cytomegalovirus, and HBsAg in the renal tissue were detected. HBsAg is detected in the renal tissue mainly in the children without free HBsAg in the blood serum. This may be indicative of an important role of specific immune complexes in the pathogenesis of glomerulonephritis associated with hepatitis B viral infection. The results point to an appreciable contribution of a persistent viral infection to the progress of glomerulonephritis.
