title: The functional significance of the skin's stratum lucidum.
abstract: The molecular structure of the skin's stratum lucidum, rich in energetic enzymes and SH groups secreted by the granular cells, was shown by histochemical methods. These active extracellular elements represent a functional barrier which ensures the organism-environment exchanges under the impulse and control of nucleic acids. The biological basis of the cutaneous absorption is discussed.
