A series of in situ gelable hydrogels were prepared from oxidized dextran (Odex) and N-carboxyethyl chitosan (CEC) without any extraneous crosslinking agent. The gelation readily took place at physiological pH and body temperature. The gelation process was monitored rheologically, and

To develop and evaluate a bioresorbable spherical material for embolization. New bioresorbable hydrogel microspheres were prepared from carboxymethyl cellulose and chitosan by using an inverse emulsion method. Size distribution of the microspheres was determined with a microscope, and the colorability
