[Diagnosis and tactics in multiple trauma].

It is difficult to establish the diagnosis in combined injuries because of the peculiar pathogenesis leading to unusual symptomatology and diagnostic errors. This is associated with some peculiarities of a combined injury: it is marked by the syndrome of mutual aggravation; signs of less severe injuries often come to the forefront; the usual complex of symptoms may be indistinct or even absent. For instance, in internal hemorrhage combined with contusion of the brain arterial pressure may be normal or even increased, while the signs of "acute abdomen" may not be manifested as the result of diminished abdominal reflexes.

[Potentiation of the action of antibiotics by ultrasound].

The aim of the study was to investigate the action of ultrasound on antimicrobial drugs and to estimate the effect of antibacterial drugs and ultrasound used in combination and alone. In the first series of the experiments it was shown that under the action of ultrasound such antibiotics as benzylpenicillin, streptomycin, ampicillin, lincomycin, monomycin, rifampicin and gentamicin, and antiseptic drugs such as furacin, rivanol and iodinol did not change their antibacterial (bacteriostatic and bactericidal) properties with regard to Staphylococcus aureus and Escherichia coli. In the second series of the experiments it was shown that ultrasound potentiated by 1.
