[Effect of an interferon preparation on increasing bacterial sensitivity to antibiotics].

Under the effect of human leukocytic alpha-interferon-II for injections there was observed an increase in sensitivity of bacteria to benzylpenicillin, ristomycin, novobiocin, streptomycin, kanamycin, monomycin and erythromycin. A higher antibacterial effect of the penicillin and erythromycin was recorded only with respect to initially resistant strains of staphylococci. For the antibiotic resistant strains of staphylococci the MICs of the penicillin and erythromycin decreased on the average 17.

[Partial purification and various characteristics of antibacterial factor in preparations of interferon].

A factor showing antibacterial activity was isolated from human alpha-interferon native preparations with affinity chromatography on immobilized cells of staphylococci. The antibacterial activity was found to be stable to the effect of nucleases and heating. Exposure to trypsin activated the antibacterial activity while exposure to pepsin somewhat destroyed it.

[Laser therapy of mandibular fractures].

Results of a comparative analysis of treatment of 46 patients with mandible fractures show the laser radiation (1 mv/cm2) to enhance the activity of serum alkaline phosphatase, to accelerate fixation of the mandible fracture, to shorten the period of disability of the patients, to prevent inflammatory complications.
