IN VIVO STIMULATION OF PERITONEAL CELLS BY CHITOSAN ADMINISTERED IN DRINKING WATER TO MICE
Journal Title: Progress on Chemistry and Application of Chitin and its Derivatives - Year 2012, Vol 0, Issue
Abstract
The aim of the study was to determine immunostimulant properties of chitosan administered alimentary to BALB/c mice. We observed that chitosan feeding effected in activation of cells from the peritoneal cavity. The cells produced less nitric oxide with simultaneous enhanced activity of arginase and higher expression of receptor for IL-4. What is more, chitosan caused increased number of cells expressing MHC class II. The study confirms that chitosan can stimulate immune system what potentially makes it useful candidate for adjuvant.

CHITOSAN AND CHITOSAN-POLYETHYLENIMINE MICROSPHERES PREPARED BY MEMBRANE EMULSIFICATION AND THEIR APPLICATION FOR DRUG DELIVERY SYSTEMS
The aim of this paper was to prepare chitosan microspheres characterised by a narrow dispersion of dimensions, suitable for application for drug delivery systems (DDS). The materials, unmodified as well as functionalised...
MECHANISM OF WATER DIFFUSION INTO NONCROSSLINKED AND IONICALLY CROSSLINKED CHITOSAN MEMBRANES
Ionically crosslinked chitosan membranes were prepared and their swelling behaviour was analysed. Low‑molecular pentasodium tripolyphosphate (TPP) and/or high‑molecular sodium alginate (NaAlg) were used as ionic crosslin...
VAPOUR PERMEATION STUDY OF WATER AND ETHANOL THROUGH CROSSLINKED CHITOSAN AND ALGINATE MEMBRANES
A vapour permeation of water and ethanol through homogenous chitosan and alginate membranes was investigated. The influence of the polymer matrix and crosslinking agents, and measurement protocol on the transport propert...
VISCOMETRIC STUDIES OF MICROCRYSTALLINE CHITOSAN/POLY(VINYL ALCOHOL) MIXTURES
In the present paper, the results of viscosity measurements in dilute solutions of microcrystalline chitosan (MCCh) with poly(vinyl alcohol) (PVA) of different degrees of hydrolysis are presented. Microcrystalline chitos...
RESEARCH OF PHARMACEUTICAL PROPERTIES OF HYDROPHILIC POWDERS CONTAINING LACTIC ACID COMPLEXED WITH CHITOSAN
Hydrophilic powders passing gels containing lactic acid complexed with chitosan at a stoichiometric ratio of 1:1 and 8:1 revealed pH ranged from 3.92 to 4.44 and 2.36 to 2.84. Rheological studies demonstrated that the re...
