| Research Abstract |
1 : The present study was performed to macroscopically and histologically investigate wound healing responses in defects of the beagles palatal mucoperiosteum after implantations of TERUDERMIS and no implantations.
2 : The TERUDERMIS group exhibited better arrest of hemorrhage than the control group.
3 : The change of wound dimension (rate of wound contraction) of TERUDERMIS group was smaller than control group at any weeks.
4 : The TERUDERMIS group exhibited remarkably good growth of the epithelial regeneration of epithelial ridge.
5 : In connective tissue of the TERUDERMIS group, there were rich wide collagen fibers and so called 'pseudo-dermis were looked at 4 weeks. In control group, there were crudly thin collagen fibers and narbig connective tissue were looked.
6 : The process of absorption of the TERUDERMIS was also observed using immunostainning with antibovine serum monoclonal antibodies. The antibovine serum monoclonal antibodies was persistence at 2 weeks, but at 4 weeks that was not persistence. TERUDERMIS reconstructed completely the self connective tissue.
7 : The above results suggest the TERUDERMIS is available as an 'artificial mucous membrane' in defects of the mucoperiosteum.
