title: Dual nature of the intracellular cations. Conductance of adsorbed intracellular cations in the region of microwave frequencies.
abstract: The majority of intracellular ions was "invisible" by classical conductance measurements over the regions of audio and radio frequencies. In the microwave region all the cations become "visible" in muscles. A non-invasive method is found to determine the cationic content of biological tissues. The better the physical condition of the muscle the greater the new parameter, the invisible cationic conductivity. 15% of the total cation content is released by thermal treatment that was probably associated with negative phosphate or carboxylate groups of the lipoid surface of the membrane structure. This K+ fraction in the frog muscle has been already discovered by three quite different methods.
