The in vitro biocompatibihty of wound dressings in regards to fibroblasts has been assessed and compared with three commercial wound dressings made of collagen, alginate and gelatin. Methylpyrrolidinone chitosan and collagen were found to be the most compatible materials [305,306],... [Pg.192]

Chitosan has been associated with other biopolymers and with synthetic polymer dispersions to produce wound dressings. Biosynthetic wound dressings composed of a spongy sheet of chitosan and collagen, laminated with a gentamicyn sulphate-impregnated polyurethane membrane, have been produced and clinically tested with good results.

When chitosan is added to the culture medium the BC/chitosan composites formed include the properties of both components, mainly an extraordinary bactericidal and barrier effect against microorganisms. Therefore, this modified BC is well suited for wound dressings [42]. [Pg.61]

In addition to the novel applications mentioned above, chitosan and chitin have been exploited in numerous areas such as wound dressing, cholesterol control, food stabilization, hair/skin care, and cell/enzyme immobilization. [Pg.494]

Treating chitin with H2O, OH hydrolyzes its amide linkages, forming a compound called chitosan. What is the stmcture of chitosan Chitosan has been used in shampoos, fibers for sutures, and wound dressings. [Pg.1061]

Quatemized chitosan (QCh) derivatives have a high activity against bacteria and thus are potential candidates for wound dressing applications. Electrospun QCh fiber mats were successfully prepared by electrospinning QCh solutions mixed with PVA [131]. The electrospun QCh/PVA fiber mats were stabilized against dissolution in aqueous environment using photomediated crosslinking. [Pg.230]

A brief review is presented of the chemical stmctures of alginate and chitosan and their performances of novel biomaterials were compared. Their uses in wound-dressing materials are outlined and binding with metal ions and antimicrobial properties are mentioned. 13 refs. [Pg.38]

Chitosan derivatives have also been studied for possible utilization in wound dressings. For example, three kinds of chitosan derivative (oligochitosan, N,0-carboxymethyl-chitosan, and Al-carboxymethyl-chitosan) are used to form sheets and pastes, all of which exhibit appropriate cytocompatibility to the fibroblasts isolated from normal human dermis and hypertrophic scars [179].
