Methods 12 guinea pigs of 20 months with 3 cm×3 cm hair sheared from their backs were divided into control group and experimental group. Rhodosin and deer serum preparation was besmeared on the skin of guinea pigs in experimental group, and cosmetic matrix was besmeared on the skin of animals in control group for 60 d. The distribution of type Ⅲ collagen was observed with Sirius red staining and HE staining. The fission index of the cells of stratum basale, the thickness proportion of stratum corneum to epidermis, the volume density of the collagen fibers and small blood vessel in dermis, the number of fibroblasts in aging skin were meassured with technique of sterology.

This in vivo study was to examine the historical changes of implanted novel chitosan/collagen composite barrier for confirming the clinical feasibility. Four other commercial GTR membranes were chosen for comparison. Among the resorbable GTR membranes, BioMend Extend and Peri-Aid are collagen base, and GORE-TEX OSSEOQUEST is synthesized membrane, while GORE-TEX e-PTFE (Expanded polytetrafluoroethylene) is synthesized but non-resorbable. Beagle dogs were used as animal model. Buccal mucoperiosteal flaps were reflected in the bilateral mandibular premolar and molar areas. Buccal alveolar bone was reduced on 1st、2nd premolar and molar to a level 5 mm apical to the cemento-enemel junction. Root surface was denuded of periodontal ligament and cementum, and notches were placed at the bone level of each root. The tested GTR barriers were implanted in critical bone defect areas. Flaps were coronally positioned and sutured. Two beagle dogs were sacrificed each time as the designed time period after surgery. Histological and histometirc evaluation at 7 dayshttps://cao127.com、14 days欧美日韩图自拍图片大全、28 days、3 months were performed post-operatively to determine the healing response of each treatment modality.
