PREPARATION AND CHARACTERIZATION OF A NEW GENERATION OF CHITOSAN HYDROGELS CONTAINING PYRIMIDINE RIBONUCLEOTIDES.

Damage to the nervous system, in particular spinal cord injuries, is a burden for the patient and is usually the cause of irreversible disability. The progress observed in the last decade in the fields of biology, biomaterial engineering and neurosurgery has created new treatment solutions while preventing further neurodegenerative processes. The most important research is focused on the implementation of polymer structures in clinical practice, especially chitosan hydrogels, which are the scaffolds for regenerating axons. This article presents a new generation of biomaterials that have the ability to gel in response to temperature changes; they are intended for injectable scaffolds for nerve cell cultures. Two types of hydrogels were prepared based on chitosan lactate and chitosan chloride using uridine 5'-monophosphate disodium salt. The structure of the systems was observed under a scanning electron microscope and examined using Fourier transform infrared spectroscopy. In addition, thermal properties were tested using differential scanning calorimetry. [ABSTRACT FROM AUTHOR]
