[Protective activity of panavir in experimental rabies infection]

Significant and reliable activity of panavir was shown in experiments on mice intramuscularly infected with the rabies virus. The animal protection depended on the dose of panavir and the treatment scheme. The reliable protection (30-45% of the mice, p<0.05-0.01) was observed only after the panavir intramuscular injection to the site of the virus inoculation (the infection atrium), but not after the systemic (intraperitoneal) administration. High titers of the virus-neutralizing antibodies (7.92-10.45 IU/ml), comparable to the antibody titers in the combined suspensions of the brain tissues (6.01-10.45% IU/ml), were detected in the combined sera of the survived animals treated with panavir. For the first time a quantitative method for determination of the virus-neutralizing antibody levels in IU/ml was used (the FAVN test, the gold standard for comparative evaluation of the level of the vaccinal and infective antirabies immunity).
