Periosteal osteosarcoma is a distinct entity of malignant bone tumor with characteristic clinical, morphological, and histological features within the group of juxtacortical osteosarcoma. Periosteal osteosarcoma is predominantly located in the tubular long bones, and extremely rarely involving the jaws. A case of periosteal osteosarcoma of the right mandible is presented. A 27-year-old woman complained of the gingival swelling and bleeding tendency of the right posterior mandible. Clinical examination revealed a reddish brown strawberry-like swelling on the affected mucosa, which measured 1.5㎝×1.5㎝. The tumor was located on the lingual cortex of the mandible and extended into the surrounding soft tissues. Microscopically, the tumor consisted exclusively of atypical chondroblastic cells with a small osteoblastic area. A minimal bone marrow involvement was noted and the adjacent cortex was free of tumor. These findings suggested that the tumor originated from the periosteal cambium layer, which lies between the periosteal fibrous layer and the cortex of mandible.

ADP에 의해서 활성화된 인혈관세포의 Prothrombin과 골타액단백 부착에 관여하는 Integrin avβ3, avβ5, a5β1의 특성

주승재,최휘,김성만,차태준,이재우 고신대학교 의학부 2003 高神大學校 醫學部 論文集 Vol.18 No.1

Background : One of the most important features of integrins is that they exist in active and inactive states. Adenosine diphosphate (ADP), which is usually secreted from activated platelets, may activate integrins on vascular on vascular cells. Each integrin has its own activation-dependent ligands that have much higher affinity to active form than inactive one. Integrins that might mediate adhesion of human vascular cells to prothrombin(PT) and bone sialoprotein (BSP) after ADP stimulation were investigated. Methods : PT and BSP were used as activation-dependent ligands in adhesion assay. Adhesions of human umbilical vein endothelial cells (HUVEC) and human aortic smooth muscle cells (HASMC) were measured after stimulating with 100 μM of ADP, using ligand-coated 24-well plate and Fluorescence Multi-Well Plate Reader. Results : ADP activated HUVEC and HASMC to increase adhesions to PT and BSP in a dose-dependent manner. Adhesions of ADP-stimulated HUVEC to PT and BSP were almost completely inhibited by c7E3, a blocking monoclonal Ab to integrin β₃(96% and 92% inhibition, respectively), but not by P5H9, a blocking monoclonal Ab to integrin α_vβ_5. Adhesion of ADP-stimulated HASMC to PT was completely blocked by P5H9 (92% inhibition), but was not affected by c7E3. Adhesion of ADP-stimulated HASMC to BSP was partially inhibited either by P5H9 (46% inhibition) or by JBS5, a blocking monoclonal Ab to integrin inhibition), but was not affected by c7E3. However, it was completely blocked by cRGD (93% inhibition). Conclusion : These results indicate that the adhesion of ADP-stimulated HUVEC to PT or BSP was mediated by integrin α_vβ₃ and several integrins appeared to be involved in the adhesion of ADP-stimulated HASMC. While the adhesion of HASMC to PT was mediated by integrin α_vβ_5, the adhesion to BSP was associated with integrins α_vβ_5 and α_5β₁.

본 연구는 미니 임플란트 식립 후 교정력 부하시기와 관련하여 임플란트 주위골의 치유과정을 조사하였다. 성견8마리의 하악 협측골에 교정용 미니 임플란트(ORLUS, Ortholution CO, Korea) 48개를 식립한 후 교정력을 주지 않은 대조군과 식립 후 즉시 교정력을 준 즉시 부하군, 그리고 식립 후 3주간의 치유기간을 두고 교정력을 준 지연 부하군으로 나누어 각각의 군에 대해 3주, 6주, 12주가 경과된 시점에 임플란트 주위골의 변화를 조직 계측학적으로 관찰하였다. 골 접촉률은 즉시 부하군에서 시기에 따른 유의한 변화가 없었으며 지연 부하군은 3주에 비해 12주에서 유의하게 증가하였다 (p < 0.05). 각 시점에서 군 간의 골 접촉률을 비교했을 때 12주째 지연 부하군이 즉시 부하군보다 유의하게 높았다 (p < 0.05). 골 면적비율은 즉시 부하군의 경우, 시기에 따른 유의한 변화가 없었으며, 지연 부하군과 대조군은 6주에 비해 12주째 유의한 증가를 보였으며 (p < 0.05), 12주째 실험군 간에 유의한 차이는 관찰되지 않았다 (p > 0.05). 동요도는 12주째 즉시 부하군과 지연 부하군 간에 유의한 차이는 없었다 (p > 0.05). 위의 결과에서 즉시 부하가 self drilling형 미니 임플란트 주위골의 안정성에 부정적인 영향을 주지 않았으므로 식립 즉시 교정력을 부여하여 사용하는 데 임상적으로 문제가 없을 것으로 판단된다. Objective: The purpose of this study was to investigate the stability of mini-implants in relation to loading time. Methods: A total of 48 mini-implants (ORLUS, Ortholution, Korea) were placed into the buccal alveolar bone of the mandible in 8 male beagle dogs. Orthodontic force (200 - 250 gm) was applied immediately for the immediate loading group while force application was delayed for 3 weeks in the delayed loading group. For the subsequent loading periods (3, 6, 12 weeks), BIC (bone implant contact) and BV/TV (bone volume/total volume) and mobility test were carried out. Results: The immediate loading group showed no changes in BIC from 3 to 12 weeks, while the delayed loading group showed a significant increase in BIC between 3 and 12 weeks (p < 0.05). The BV/TV of the delayed loading group significantly increased from 6 to 12 weeks of loading (p < 0.05), while the BV/TV of the immediate loading group decreased from 3 to 12 weeks of loading. However, there was no significant difference in BV/TV between experimental groups. The mobility of the immediate loading group was not significantly different from that of the delayed loading group after 12 weeks of loading (p < 0.05). Conclusions: These results showed that immediate loading does not have a negative effect on the stability of mini-implants compared to the early loading method in both the clinical and histomorphometric point of view.

Epidemiological studies suggest that 30-50% of patients diagnosed with symptomatic congestive heart failure(CHF) have electrocardiographic evidence of a major intraventricular conduction delay, which may worsen left ventricular systolic and diastolic dysfunction through asynchronous ventricular contraction and paradoxical interventricular septal wall motion. Biventricular pacing is an emerging therapy allowing simultaneous electrical stimulation of the both ventricles with an implantable pacing system and it improves hemodynamics and well-being of patient by reducing ventricular asynchrony. Recently, we underwent biventricular DDD pacemaker implantation in a patient with CHF and Left bundle branch block and was significantly improved exercise tolerance and quality of life in that patient.
