The structure of dehydrated epidermis and changes in light dispersion in water solution of glucose as the main component of inter-desmosome bridges under influence of constant magnetic field have been experimentally studied. On the basis of the results obtained these bridges are assumed to play key role in disordering the horny layer under the action of constant magnetic field. This assumption agrees with the results of clinical research.展开更多
