        Rat Defect Models for Bone Grafts and Tissue Engineered Bone Constructs

        김중현,김해원 한국조직공학과 재생의학회 2013 조직공학과 재생의학 Vol.10 No.6

        The development of optimized biomaterials for restoring bone defects has been ongoing for many years. Animal models for testing bone grafts and tissue engineered constructs are an important aspect of this research. New bone scaffolding systems need to be tested both in vitro and in vivo, but ultimately animal studies provide answers and confidence in their efficacy prior to clinical applications. A robust set of rat models for understanding bone development in response to implanted materials have been developed. This review will describe frequently used rat bone defect models, such as the calvarial defect, long bone defect, and maxillofacial bone defect models.

This study was carried out to investigate the flora of Deokjeongsan Mt. (Ganghwa-gun) from March to October 2016. The vascular plants identified during the 8 round field surveys were a to total of 484 taxa: 107 families, 305 genera, 423 species, 8 subspecies, 48 varieties, 4 forms and 1 hybrid. The plant formation of Deokjeongsan Mt. is the deciduous broad-leaved and conifer mixed forest which is the common one in the middle part of Korean peninsula. All most mountain covered with young secondary forest which is mainly composed of Pinus and Quercus. The plant species diversity largest families were Asteraceae (62 taxa, 12.7%), Poaceae (48 taxa, 9.9%), Cyperaceae (27 taxa, 5.6%), Fabaceae (23 taxa, 4.7%), and Lamiaceae (21 taxa, 4.3%). The four taxa of Korean endemic plants such as Clematis brachyura Maxim., Salix koriyanagi Kimura ex Goerz, Carex brevispicula G. H. Nam & G. Y. Chung, and Hemerocallis hakuunensis Nakai were collected. The vascular plants on the red list according to IUCN evaluation basis were found to be five taxa: Near Threatened (NT) species of Senecio argunensis Turcz., Least Concern (LC) species Pseudoraphis ukishiba Nakai, and Not Evaluate (NE) species of Thladiantha dubia Bunge, Cirsium lineare (Thunb.) Sch. Bip., and Scorzonera austriaca ssp. glabra Lipsch. & Krasch. ex Lipsch., respectively. The floristic regional indicator plants found in this area were 26 taxa comprising one taxa of degree V, two taxa of degree IV, four taxa of degree III, eight taxa of degree II, and 11 taxa of degree I. In addition, the alien plants were identified as 46 taxa and the percentage of naturalized index (NI) was 9.5%, and urbanization index (UI) was 14.3%, respectively.

        This study was carried out to investigate the flora of Jingangsan Mt. (Ganghwa-gun). The vascular plants identified during the 11 round field surveys were a to total of 560 taxa: 114 families, 336 genera, 495 species, 7 subspecies, 53 varieties, 4 forms and 1 hybrid. A high plant diversity were Poaceae (11.0%), Asteraceae (10.8%), Cyperaceae (8.8%), Rosaceae (4.6%) and Lamiaceae (4.3%) in regular order.

        Vascular plant diversity of the Gogunsan Archipelago in the Korean Peninsula

        김중현,이병윤,남기흠,박환준,김진석,이경위,장연순,안지홍 국립생물자원관 2019 Journal of species research Vol.8 No.1

        This study was carried out to investigate the flora of six islands belonging to the Gogunsan Archipelago (i.e.,Sinsi-do, Seonyu-do, Munyeo-do, Yami-do, Bian-do, and Duri-do) in the Korean Peninsula. As results of five field surveys from March to October of 2016, we have identified 575 total taxa, representing 527 species, five subspecies, 42 varieties, and one hybrid, placed in 358 genera and 118 families. Of these 575 taxa, four are endemic to Korea, six taxa are listed on the Korean Red List of threatened species, 67 are floristic regional indicator plants, and 74 are invasive alien species. In this study, we compared species richness among the islands, and find that the larger the islands, the higher the species richness. In the case of habitat affinity types, forest species were most common, followed by farmland, seacoast, bare ground and wetland species. From similarity analyses based on the composition of vascular plants, each island did not exhibit either local specificity or unique diversity. On the contrary, the proportion of invasive alien and ruderal species may increase by human activities. Investigations and analyses of island flora such as this are important to assess the current status of the flora, predict future vegetation patterns and the spread of the alien species, and establish managment plans of plant diversity.
