摘要:
The object of the present invention relates to the new and surprising use of sulfated hyaluronic acid (HAS) as regulator agent of the cytokine activity (pro- and anti-inflammatory) and consequently the use of HAS for the preparation of a new medicine for topic use in the prevention and treatment of pathologies associated with the activation and/or deficiency of cytokines of a pro- and anti-inflammatory nature. The Applicant has in fact discovered the exclusive capacity of HAS in modulating the activity of these particular proteins, it has studied the action mechanism and demonstrated the substantial difference between the different sulfated types known in the state of the art, but above all it has demonstrated an unexpectedly high activity of HAS vs different types and strains of Herpes virus, Cytomegalovirus and the virus of vesicular stomatitis. Finally, a further object of the present invention is the use of HAS as a skin absorption promoter of drugs of an anti-inflammatory nature.
摘要:
The present invention regards a biological material comprising: a) a liquid carrier comprising a viscous solution containing at least one natural and/or semisynthetic polysaccharide, and having a Dynamic viscosity measured at 20° C. and at shear rate of D=350 s−1, comprised between 100 and 250 c Poise and/or a Kinematic viscosity comprised between 99 and 248cSt (measured at the same conditions); b) a culture of mesenchymal stem cells, and/or c) a platelet-rich hemo-derivative. This type of material in form of viscous liquid is particularly suitable for the therapy of osteoarthrosis, ligament damage, in particular tendon and cartilage damage) and may be administered intra-articularly, intradermally or directly applied in situ without altering the properties of the mesenchymal stem cells and/or platelets contained therein.
