We carried out about sequestrum caused by carbon-ion radiation of the patients with head and neck tumors. There were 13 patients who were operated of sequestrotomy at Ichikawa General Hospital, Tokyo Dental College from 2000 to 2007. We compared the CT images of nine out of thirteen patients pre radiation with post sequestrotomy to investigate the dose distribution. Six out of nine patients, the area of post sequestrotomy were corresponded with the highest dose area.H１９年度HIMAC共同利用研究成果発表

The results showed that the process parameters had little effect on pectin DH, remarkable effect on galacturonic acid content, and the largest effect on viscosityaverage molecular mass. The 9 orthogonal array runs resulted in a DH of 63.5%-63.8%, a galacturonic acid content of 74.2%－88.5% and a viscosity-average molecular weight of 101－202 ku.福建省科技计划重点项目(2010Y0035
