Characterization of the visco-elastic properties of hyaluronic acid.
Background: Hyaluronic acid (HA) is a polysaccharide present in almost all animal tissues, in which it carries out important biological functions, among them, the protection of the joints by lubricating them and dampening the tension in them.
Objective: This study compares the viscoelastic properties of several commercial preparations of HA, to determine their suitability for use as viscosupplementation therapy in joint pathology (osteoarthritis).
Methods: 4 HA hydrogels: Durolane®, Synocrom_Forte_One®, Synvisc_One® and Viscoplus_Matrix® and 4 HA solutions: Ostenil®, Ostenil_Plus®, Viscoplus_Gel® and Orthovisc® were analyzed to compare their viscoelatsic rheological parameters using an oscillatory-rotational rheometer.
Results: With respect to the 4 HA hydrogels, comparison of crossover frequencies allowed division into two main groups: Synvisc_One® and Viscoplus_Matrix®, with crossover frequencies in the order of magnitude of 10-2 Hz, while Synocrom_Forte_One® and Durolane® showed crossover frequencies on the order of 10-1 Hz. Only one of the 4 HA solutions, Viscoplus_Gel®, showed a crossover frequency on the order of 10-2, whereas Ostenil_Plus® and Orthovisc® showed crossover frequencies on the order of 10-1, and Ostenil® remained as a predominantly viscous fluid for frequencies as high as 4.8 Hz.
Conclusions: The viscoelastic properties of the HA preparations can be ordered according to the values of G∗ (the rigidity, or vector sum of the elastic modulus G' and the viscous modulus G'') at both transition points (0.5 and 2.5 Hz) as follows: Viscoplus_Matrix® > Viscoplus_Gel® > Durolane® > Synocrom_Forte_One® > Ostenil_Plus® > Synvisc_One® > Orthovisc® > Ostenil®.
期刊介绍：
Biorheology is an international interdisciplinary journal that publishes research on the deformation and flow properties of biological systems or materials. It is the aim of the editors and publishers of Biorheology to bring together contributions from those working in various fields of biorheological research from all over the world. A diverse editorial board with broad international representation provides guidance and expertise in wide-ranging applications of rheological methods to biological systems and materials.
The scope of papers solicited by Biorheology extends to systems at different levels of organization that have never been studied before, or, if studied previously, have either never been analyzed in terms of their rheological properties or have not been studied from the point of view of the rheological matching between their structural and functional properties. This biorheological approach applies in particular to molecular studies where changes of physical properties and conformation are investigated without reference to how the process actually takes place, how the forces generated are matched to the properties of the structures and environment concerned, proper time scales, or what structures or strength of structures are required.
