Abstract:
Objective To explore the effects of ecoimmunonutrition support on the intestinal barrier function and pancreas in rats with severe acute pancreatitis (SAP). Methods Totally 64 SPF rats were randomly divided into sham operation group (control group) , SAP without enteral nutrition support group (SAP group), SAP with early enteral nutrition support group (EEN group), and SAP with early ecoimmunonutrition support group (EIN group). Bacteria translocation (BT), plasma endotoxin (ET) , gut permeability, pancreas pathology score,and distant ileum pathology were determined on the 4th and 7th post-modeling day. Results The BT rate was significantly higher in SAP group, EEN group, and EIN group than in control group (P ＜ 0.05), was significantly lower in EEN group and EIN group than in SAP group (P ＜ 0.05), and was significantly lower in EIN group than in EEN group (P ＜ 0.05). ET and FD-40 levels in blood were both significantly higher in SAP group, EEN group, and EIN group than in control group (P ＜0.01)and were significantly lower in EIN group and EEN group than in SAP group (P ＜0.01); ET was significantly lower in EIN group than in control group (P ＜0.05). Pathological scores were significantly higher in SAP group, EEN group, and EIN group than in control group (P ＜0.01)and were significantly lower in EEN group and EIN group than in SAP group (P ＜ 0.01). The individual pathological scores of EIN group were not significantly different from EEN group (P ＞ 0.05), while the total score was significantly lower in EIN group than in EEN group (P ＞ 0.05). Distant iliac mucosa was significantly thicker in EIN group than in other groups. Conclusions Early enteral nutrition support protects the intestinal barrier and pancreas in rats with SAP. Ecoimmunonutrition has better nutritional effectiveness than the normal enteral nutrition.
