Preparation of Phenytoin Sodium Carboxymethyl Chitosan Microsphere and Its Bacteriostasis Experiment Research on Periodontal Common Pathogenic Bacteria
OBJECTIVE To optimize the preparation of phenytoin sodium carboxymethyl chitosan microspheres(PHT-CMCS-MS) using orthogonal test method, and to analyze the components' bacteriostatic effects of two common pathogenic bacteria of periodontal. METHODS The preparation of PHT-CMCS-MS used emulsion chemical cross-linking method and orthogonal test method, with drug loading and entrapment efficiency as index, preparation technology was optimized.Then surfaces of the microspheres were observed, release property and...
