Preparation and Treatment for Oral Ulcer of Quercetin and the Drug-Loaded Chitosan Composite Material

Abstract
With the drug-loaded chitosan as film forming materials, use salivation method to prepare Quercetin-chitosan composite film of oral ulcer and use this film to the treatment for the rat model of oral ulcer. To study the therapeutic effect for oral ulcer of the Quercetin-Chitosan composite film by measuring the area, the volume and the healing speed of the ulcer, observing edema and congestion degree of ulcer surface, and detecting the pathological changes of ulcer tissue by HE staining.
