Summary
New polymeric scaffolds using chitosan and alginate were developed for veterinary tissue regeneration. These biocompatible scaffolds demonstrated effective bone defect repair in rabbits, with optimized drug release profiles for oxytetracycline hydrochloride (OTC).
Area of Science:
- Biomaterials Science
- Veterinary Medicine
- Tissue Engineering
Background:
- Polymeric scaffolds are crucial for tissue regeneration.
- Oxytetracycline hydrochloride (OTC) is a vital antibiotic in veterinary medicine.
- Developing effective delivery systems for antibiotics in veterinary applications is essential.
Purpose of the Study:
- To develop and characterize polymeric scaffolds for veterinary tissue regeneration.
- To incorporate and evaluate the release of oxytetracycline hydrochloride (OTC) from these scaffolds.
- To assess the in vivo biocompatibility and efficacy of the scaffolds in bone defect repair.
Main Methods:
- Chitosan and alginate gels and sponges were prepared using distilled water or acetic acid.
- Tripolyphosphate was used for cross-linking.
- Viscosity, water absorption, and OTC release were analyzed.
- In vivo biocompatibility and bone regeneration were evaluated in rabbit radius defects.
Main Results:
- Chitosan/alginate sponges exhibited the highest water absorption.
- Cross-linking increased OTC release from sponges.
- Chitosan/alginate sponges showed the slowest and lowest OTC release.
- Formulations were biocompatible and promoted new bone organization without significant OTC enhancement.
Conclusions:
- Chitosan/alginate sponges offer a promising platform for veterinary tissue regeneration with tunable drug release.
- The developed scaffolds are biocompatible and support bone defect healing in vivo.
- Further optimization may be needed to enhance the therapeutic effect of incorporated antibiotics.
