PRELIMINARY STUDIES ON THE USABLE PROPERTIES OF INNOVATIVE WOUND DRESSINGS
Journal Title: Progress on Chemistry and Application of Chitin and its Derivatives - Year 2011, Vol 0, Issue
Abstract
There is endless and growing demand on a novel and innovative wound dressings, which except basic protective performance accelerate the process of wounds healing and/or replace the patient skin function. The studies on the new wound dressings result from the need of the quick and effective treatment of wounds, such as: having no tendency to heal, posttraumatic wounds, scalding wounds, ulcerations or bedsores. Chitosan is a biopolymer originated from chitin by N-acetylation. Due to the special behavior, such as: biological activity, it is linked to polymers having several and multifunctional applications, especially for designing of medical devices. The aim of the research was to evaluate the comprehensive performance of several kinds of chitosan prototypes of innovative wound dressings made of various usable form of chitosan. The evaluation of mentioned prototypes of wound dressing was carried out using the guidelines from series of PN-EN 13726 Standards harmonized with UE Directive 93/42/EEC and 2007/47/WE for medical devices

PHYSICOCHEMICAL PROPERTIES OF CHITIN ISOLATED FROM SHELL OF INDUSTRIAL CRABS OF VARIOUS SPECIES
Differential thermal analysis was carried out over the range of –190 ÷ 400 °С on six samples of chitin from shells of industrial crabs of various species. All samples of the chitin have several relaxation transitions of...
INFLUENCE OF POLOXAMER 407 ON THE PROPERTIES GYNECOLOGICAL POWDERS CONTAINING LACTIC ACID COMPLEXED WITH CHITOSAN
Thermosensitive hydrophilic powders passing in gels containing lactic acid complexed with chitosan at a stoichiometric ratio 1:1 and 8:1 reveal pH ranged from 4.00 to 4.91 and 2.56 to 3.42. Rheological studies demonstrat...
USE OF SAWDUST IMMOBILISED ON CHITOSAN FOR DISPOSAL OF DYES FROM WATER SOLUTIONS
In this article, the sorption properties of chitosan hydrogel beads, beech sawdust and sawdust immobilised on chitosan in relation to Reactive Black 5 (RB5) and Basic Violet 10 (BV10) dyes were compared. In the conducted...
INFLUENCE OF A POLYVINYL ALKOHOL AND DEXTRANE ON THE PROPERTIES OF HYDROPHILIC GELS CONTAINING LACTIC ACID COMPLEX WITH CHITOSAN
The investigated preparations on methylcellulose base revealed good adhesion to the vaginal mucosa and were present on it throughout the daily activities of the patient. This property enabled the continuity of 24-hour ac...
THERMAL DEGRADATION OF DOUBLE CROSSLINKED HYDROGEL CHITOSAN MEMBRANES
The thermal degradation behaviour of uncrosslinked and crosslinked chitosan membranes were studied by means of dynamic thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC) over the temperature ran...
