5.Effects of low dose irradiation on the calcific nodule formation in MC3T3-E1 osteoblastic cell line.
Korean Journal of Oral and Maxillofacial Radiology 2004;34(3):137-144
PURPOSE: To investigate the effects of low dose irradiation on the calcium content and calcific nodule formation of the MC3T3-E1 osteoblastic cell line. MATERIALS AND METHODS: Cells were irradiated with a single dose of 0.2, 0.4 and 0.6 Gy at a dose rate of 5.38 Gy/min using Cs-137 irradiator. After irradiation, the calcium content and calcific nodule formation were examined on the 1st, 2nd, 3rd and 4th week. RESULTS: We did not find any significant difference of total calcium content after irradiation of 0.2, 0.4 and 0.6 Gy when compared with the unirradiated control group. There was no significant difference of total calcium content between 0.2, 0.4 and 0.6 Gy irradiated groups. We found an increased tendency of the calcific nodule formation after irradiation of 0.2, 0.4 and 0.6 Gy when compared with the unirradiated control group without significant difference of calcific nodule formation between 0.2, 0.4 and 0.6 Gy irradiated groups. CONCLUSION: The results showed an increased tendency of the calcific nodule formation after low dose irradiation. However, this tendency did not increase with the increase of irradiation dose.

Recent investigations have demonstrated extensive reciprocal interactions between the immune and skeletal systems, resulting in the establishment of osteoimmunology as a cross-disciplinary field. Here we highlight core concepts and recent advances in this emerging area of study.

In clinical therapy, the current goal of dental implants is to enhance quantity and quality of osseointegration. Surface roughness and oxide structure are considered to influence the behavior of adherent cells. The purpose of this study is to evaluate the effect of different surface treatment on cellular response. The attachment and proliferation of osteoblast-like cell on sandblasted, sandblasted and etched, thermal oxidated surfaces have been compared. Sandblasting was done with Al2O3 particles(grain size of 50micrometer), etching was processed with NH4OH : H2O2 : H2O(1:1:5) at 90degrees C for 1 minute. Thermal oxidation was followed sandblasting and etching at 400degrees C, 600degrees C, 800degrees C for 2 hours. Measurement of surface roughness after the different treatment did not show any differences of Ra value between terated surfaces. Cell attachment and proliferation were increased during experiment period, but no difference was observed. SEM evaluation revealed a similar pattern of osteoblastlike cells, well attached with dendritic extension and producing numerous matrix vesicles on cell surface. The results of this study showed that oxide layer alteration by thermal oxidation did not affect the attachment and proliferation of osteoblast-like cells. This suggests the possibility that the cellular responses are further influenced by surface roughness than titaniun oxide structure. This study was supported by a grant(HMP-98-G-2-035-B) of the HAN(highly advanced National) Projected, Ministry of Health & Welfare, R.O.K
