The data оп cytotoxicity and antiviral activity of commercial antivirals, such as Remantadine, Oseltamivir, Arbidol and Ribavirin in the MDCK cell culture infected with highly pathogenic (H5N1) and pandemic 2009 (H1N1) influenza A viruses are presented. The study of the antiviral activity of antivirals in the MDCK cells culture demonstrated that Arbidol, Rimantadine and Ribavirin efficiently inhibited reproduction of the highly pathogenic H5N1 influenza viruses isolated from sick birds. Arbidol and Oseltamivir carboxylate selectively inhibited reproduction of the pandemic 2009 H1N1 influenza A viruses with changed specificity to the cell receptors, causing severe influenza in men, while remantadine had no effect on their reproduction.

Characteristics of the use of ertapenem, a beta-lactam antibiotic of the carbapenem group, are discussed.

The use of immunomodulators in the treatment of subjects with postvaccinal reactions to TEOVac was investigated. The most effective schemes were shown to be those with the use of viferon or combination of arbidol and licopide. The terms of the response signs cupping off were much shorter vs. the cases treated with polyoxidonium. The immunomodulating factors did not affect the intensity of the immunity to the vaccine virus.

Cases of sepsis with bacteriemia detected in the S.P. Botkin State Clinical Hospital within 2000-2007 were analysed. The sources of the bacteriemia, the etiological pattern of the pathogens and their susceptibility to antibacterials were estimated. The study enrolled 256 patients with sepsis. The antibiotic susceptibility of 227 isolates from the blood samples was tested. More than a half of the infection sources was detected in the organs of the respiratory tract and abdominal cavity. All the grampositive pathogens were susceptible to vancomycin and linesolid. The overwhelming majority of the enterococcal isolates proved to be susceptible to carbapenem and cefepim.

The role of reamberin, a succinate-containing infusion preparation in correlation of pulmonary metabolic and respiratory disturbances in patients with obstetric puerperal sepsis was estimated. The prospective randomized study enrolled 43 patients with puerperal obstetric sepsis complicated by polyorganic deficiency (SOFA 8-10). Nineteen patients of the 1st group and 24 patients of the 2nd group were additionally treated with reamberin in a dose of 800 ml/day for 8 days. The venous and arterial difference by glucose, lactate, pyruvate, diene conjugates, malondialdehyde and ceruloplasmin was investigated. The blood gases were determined with the Ciba Corning 45 apparatus. Lower metabolic activity of the lungs with prevalence of the glucose anaerobic metabolism and lower activity of the intrapulmonary antioxidant protection were observed in the patients with obstetric sepsis. The use of reamberin in the complex therapy of obstetric sepsis promoted maintenance of the initial balance and anaeroibic and aerobic pulmonary metabolism, thus providing shorter terms of the decompensation and recovery of the lungs respiratory function.

The results of clinical and laboratory examination of 107 children suffering from chronic hepatitis B or C were analysed. The biochemical criteria of the endogenous intoxication were investigated. Specific blood tests with antiviral drugs were conducted before the treatment and individual therapy schemes were assigned according to the tests' results. The early and sustained virological response rates during the individual antiviral treatment of the children with chronic hepatitis C proved to be 70.83 and 62.5% respectively.

The efficacy of intraabdomlnal chemotherapy in patients with prevailing forms of colon cancer, such as peritoneal carcinomatosis, local disseminated and local recurrent colon cancer was estimated. The comparative analysis showed that the intraabdominal chemotherapy allowed to amend the remote results of the treatment in the cases with carcinomatosis, local disseminated colon cancer and local recurrence.

The data on novel polypeptide antibiotics described within the last 10-15 years, as well as new researches on the known antibiotics with respect to their mechanisms of action and microbial resistance are presented.
