Daikenchuto, a Japanese herbal drug has several effects on the digestive system, so we investigated its preventive effects in a rat model of NEC. Methods: NEC was induced in newborn rats via asphyxia (100% N2 for 90 s; every 4 h) + LPS (4 mg/kg/day [administered orally on Days 0 and 1]). The effects of Daikenchuto were evaluated in 4 groups (control: 0 g/kg/day, I: 0.3 g/kg/day, II: 0.6 g/kg/day, III: 1.0 g/kg/day). Daikenchuto was administered into the stomach through a microcatheter. The incidence and severity of NEC were pathologically assessed using the NEC grade in accordance with Dovorak’s previous report. Cell positivity for inflammatory cytokine (IL-6) was also evaluated. Results: Daikenchuto reduced the incidence of NEC in control, Groups I, II, and III to 68.7%, 30.0%, 30.7%, and 13.3%, respectively. High dose Daikenchuto significantly improved the incidence of NEC, and the rate of IL-6 positive cells in group III was significantly lower than in the control group (p=0.04). Conclusion: We evaluated the effect of Daikenchuto against NEC and found that it reduced the incidence rate of NEC due to a decrease in the IL-6 production.}, school = {鹿児島大学}, title = {The novel preventive effect of Daikenchuto (TJ-100), a Japanese herbal drug, against neonatal necrotizing enterocolitis (NEC) model in rats.}, year = {2017}, yomi = {シンヤマ, シン} }
