Journal Title: Progress on Chemistry and Application of Chitin and its Derivatives - Year 2016, Vol 0, Issue
Abstract
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 demonstrated that the investigated thermosensitive gels obtained from powders have the dynamic viscosity in the ranged from 269 mPa*s to 579 mPa*s for the 1:1 stoichiometric ratio and in the range from 220 mPa*s to 530 mPa*s for 8:1 ratio. As a result of the research preparations with different pH values including the physiological range were obtained. The thermosensitive gels obtained from the thermosensitive powders were characterized by the specific dynamic viscosity. The results proved that it is possible to produce a preparation with optimal pharmaceutical and application properties.

THE INFLUENCE OF DIFFERENT KINDS OF CHITOSAN ON BIOAVAILABILITY OF ANTI-INFLAMMATORY DRUGS
Chitosan as a dietary supplement has been used in the treatment of obesity due to its capability of binding bioactive compounds. A molecule of a cationic polymer, such as chitosan, may bind acid drugs. The aim of the stu...
CHITOSAN DICARBOXYLIC ACID SALTS
It is possible to obtain salts with specified properties from adipic, succinic and fumaric acids and chitosans of varying degrees of deacetylation and viscosity-average molecular weight. The temperature of the process, t...
INFLUENCE OF THE INTERMOLECULAR INTERACTION ON PHYSICO-CHEMICAL PROPERTIES OF CHITOSAN/HYALURONIC ACID BLENDS
In the present study, the results of viscosity measurements in dilute solutions of chitosan (Ch) with hyaluronic acid (HA) are presented. Chitosan is blended with hyaluronic acid in aqueous 0.1M CH3COOH/0.2M NaCl and 0.3...
LARGE SIZE DNA IN VITRO AND IN VIVO DELIVERY USING CHITOSAN TRANSFECTION
In modern medicine, many diseases can be treated using gene therapy, which requires a DNA delivery system to prevent DNA from degradation and to transport it to the cells. Liposomal reagents are expensive for such a ther...
