The aim of this study was to evaluate the effect of Recombinant human soluble thrombomodulin (rTM) in a NEC model. NEC was induced by enteral feeding with hyperosmolar formula, gavage administration of lipopolysaccharide and asphyxia stress. In the treatment group, rTM was administered subcutaneously twice . The ileum was harvested for a histological evaluation and the measurement of the mRNA and protein expression. The rate of NEC-like intestinal injury in the treatment group (36%) was significantly lower than in the NEC group (73.5%). Tissue levels of TNF-alpha, IL-6 and HMGB1 were significantly elevated in the NEC group, whereas those in the treatment group were decreased to similar values as in the control group. Our experimental study showed that rTM is able to reduce the severity and incidence of NEC. It may be an alternative option for the treatment of NEC., 研究種目:基盤研究(C); 研究期間:2016~2019; 課題番号:16K10089; 研究分野:小児外科; 科研費の分科・細目:, application/pdf}, title = {壊死性腸炎(NEC)に対する補体系制御による治療法の開発}, year = {2020}, yomi = {タカマ, ユウイチ and タズケ, ユウコ and オクヤマ, ヒロオミ and コダマ, タスク} }
