摘要:
The present invention concerns new compositions containing hyaluronic acid or the derivatives thereof in association with the proteolytic enzyme collagenase (and relative pharmaceutical formulations) for the preparation of a dressing for topical treatment of various kinds of wounds, burns of varying depth, pressure sores, vascular ulcers and diabetic foot ulcers as well as for the treatment of hypertrophic and keloid scars.

摘要:
The invention relates to Streptomyces koganeiensis ATCC 31394 hyaluronidase having molecular weight of 21.6 kDalton, which has hyaluronidase activity and stability markedly higher than those of the hyaluronidase obtained from such microorganism to date. The invention further relates to a process for the isolation and purification of said hyaluronidase and its use for the preparation of pharmaceutical compositions or as an analytical reagent.
摘要:
The present invention relates to compositions based on silver and hyaluronic acid and their use in the management of cutaneous lesions of various origin (acute and chronic wounds, ulcerations, burns, etc.) mainly when characterized by the presence of exudate and hence at high risk of infection.
摘要:
The invention relates to topical formulations in the form of a bioadhesive hydrophilic gel comprising acyclovir as active ingredient, Sodium hyaluronate and an acrylic polymer. Said formulations improve the local administration of acyclovir in the treatment of herpes infections, because they possess good properties of adherence to the mucosa and high resistance to physiological removal mechanisms.
摘要:
Disclosed are water-in-oil (W/O) microemulsions containing as active ingredient a retinoid, a phospholipid emulsifier, and possibly hyaluronic acid or salts thereof.
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.
