[Physiology and pharmacology of hyaluronic acid].

Hyaluronic acid represents one of the main components of the extracellular matrices. Its physical-chemical and biological properties offer a wide spectrum of use of this molecule, both in industry and medical sciences. The review paper presents our contemporary knowledge gained in the research of hyaluronic acid, describing its principal behaviour in physiological and pathological processes as well as its principal pharmacokinetic and pharmacodynamic properties.
