"STUDY":{"STUDY_TITLE":"Targeted metabolomics analysis with raffinose-rich diet in mouse ileum","STUDY_TYPE":"Analysis of fructose level in ileum of stressed mouse fed with raffinose-rich diet","STUDY_SUMMARY":"Purified diet (AIN-93G) supplemented with raffinose was prepared. The mice were maintained on the separate diet for at least 1 week before the initiation of experiment.Chronic restraint stress (RS) in mice was performed 14 days.After sacrifice, the ileum of mice were used to analysis.","INSTITUTE":"China Pharmaceutical University","DEPARTMENT":"School of Medicine","LABORATORY":"Metabonomics","LAST_NAME":"Hou","FIRST_NAME":"Yuanlong","ADDRESS":"tongjiaxiang, nanjing, jiangsu, 210000, China","EMAIL":"jian2103@163.com","PHONE":"18851105337"},
