RESUMO
Dielectric permeability of the urine from healthy subjects and patients with various types of urolithiasis was studied using millimeter electromagnetic waves. The urine from healthy subjects and patients with urolithiasis differed in dielectric properties, specific water content, and structure of water. A relationship was revealed between aggregation stability of urine colloids and dielectric properties of the urine in millimeter-wave electromagnetic radiation.

The components of complex dielectric permeability of cicatricial tissue at the frequency of 55 GHz were studied during local therapy of cicatrices with Fermenkol (a complex of collagenolytic proteases). Electrical characteristics of tissues in the microwave range were interpreted in terms of hydration parameters (total content of water in tissues and the ratio of structured and free water). The rightfulness of interpretations is discussed on the basis of the results of measurements of cell suspension models (native blood and its fractions brought to a standard hematocrit). The results attest to a relationship between hydration of the cicatricial tissue and its morphology and function.
