RESUMO
In the clinic 307 patients with suppurative lesions were observed, in 183 of them (the main group) staphylococcic anatoxin was administered with prophylactic and therapeutic purposes, 124 patients (the control group) were treated with antibiotics, including 231 patients with acute appendicitis, 23--with osteomyelitis, 48--with mastitis and 5 patients with various purulent complications of staphylococcic etiology. Among 231 patients with acute appendicitis 125 comprised the main group who were injected staphylococcic anatoxin, and 106--the control group. In the latter the incidence of the operative wound suppuration was observed thrice as frequently.

The search for thermoelectric (TE) materials for highly efficient devices aims at improving the TE efficiency and broadening their areas of applications. We created nanostructured thermoelectric Bi-Sb-Te-family materials by high energy (ball milling) pre-treatment of the parent materials followed by high-pressure/high-temperature treatment. Bi0.5Sb1.5Te3 compositions with the superfluous maintenance of tellurium was used for the synthesis of the samples with p-type electrical conductivity. Acoustic microscopy was used to study elastic properties and bulk irregularities and to detection of internal cracks both in the parent materials and in the created nanostructured samples. The data has been used for optimization of parameters of synthesis of nanostructured thermoelectrics.

New metal-nanocarbon composites were obtained by high-energy (ball milling) pre-treatment of the powder mixture followed by high-pressure/high-temperature treatment. Acoustic microscopy was used to study elastic properties and bulk irregularities of the samples.
