    ABSTRACT: To evaluate the effect of enteral supplement of arginine on intestinal adaptation in rats with short bowel syndrome (SBS) and to study its mechanism. SD rats were randomly assigned to three groups: sham rats (Con), SBS rats (SB) and SBS rats supplemented with enteral arginine (SB-Arg). All the animals received isonitrogenic and isocaloric enteral nutrition, except that SB-Arg rats received enteral nutrition supplemented with arginine (300 mg kg(-1) d(-1)). Fat absorbability, plasma free fatty acids, parameters of intestinal adaptation, enterocytes proliferation and apoptosis were determined. After massive small bowel resection, rats had significant bowel adaptation. Compared with SB rats, SB-Arg rats demonstrated a significant increase in fat absorbability [(84.9+/-3.2)% vs [(81.3+/-3.9)%], plasma level of free fatty acids [(650.0+/-86.5) vs (289.5+/-76.9) mg/L], ileal mucosal weight [(18.0+/-3.5) vs (13.5+/-3.0) mg cm(-1) 100 g(-1)], ileal DNA content [(29.6+/-3.3) vs (26.0+/-2.6) microg cm(-1) 100 g(-1)], jejunal mucosal protein content [(65.5+/-7.3) vs (59.8+/-6.2) microg cm(-1) 100 g(-1)], ileal mucosal protein content[(39.2+/-2.3) vs(35.4+/-2.3) microg cm(-1) 100 g(-1)], jejunal mucosal proliferation index [31+/-4 vs 22+/-3] and ileal mucosal proliferation index [32+/-2 vs 25+/-3] (all P<0.05). Moreover, jejunal and ileal villus length, crypt depth and mucosal thickness in SBS-Arg rats were higher than those in SB rats (P<0.05). In rat SBS model, enteral supplement of arginine appears to stimulate intestinal structural and functional adaptation. The mechanism may be that arginine can stimulate enterocyte proliferation and inhibit enterocyte apoptosis.

    ABSTRACT: This study was conducted to evaluate the effects of postoperative immune enhancing enteral nutrition on the immune system, inflammatory responses, and clinical outcome of patients undergoing major abdominal surgery. This study was designed as a multicenter, prospective, randomized and controlled clinical trial. One hundred twenty-four patients undergoing major abdominal surgery were randomly assigned to receive either an immune enhancing enteral diet or an isocaloric and isonitrogenous control enteral diet for seven days. Enteral feeding was initiated 24 hours after surgery. Host immunity was evaluated by measuring levels of IgG, IgM, IgA, CD4, CD8, and CD4/CD8, and the inflammatory response was determined by assessing IL-1alpha, IL-2, IL-6, IL-10, and TNF-alpha levels. Infectious complications were also recorded. One hundred twenty patients completed the study and four patients were excluded. On postoperative day 9, among patients receiving an immune enhancing diet, IgG, IgA, CD4 and CD4/CD8 levels were significantly higher and TNF-alpha and IL-6 concentrations were significantly lower compared to the control group. Moreover, among patients receiving an immune enhancing diet, when comparing preoperation to day 9 postoperation levels, increases in IgA, CD4, and CD4/CD8 levels were significantly higher than in control patients and increases in TNF-alpha concentrations were significantly lower. No statistically significant differences were found between the two groups with regard to infectious complications. Postoperative administration of immune enhancing enteral nutrition in patients undergoing major abdominal surgery can positively modulate postoperative immunosuppressive and inflammatory responses.

    ABSTRACT: To study the intestinal permeability (IP) following stress of abdominal operation and the different effects on IP of enteral nutrition (EN) and parenteral nutrition (PN). Forty patients undergoing abdominal surgery were randomized into EN group and PN group. Each group received nutritional support of the same nitrogen and calorie from postoperative day (POD) 3 to POD 11. On the day before operation (POD-1), POD 7 and POD 12, 10 g of lactulose and 5 g of mannitol were given orally, and urine was collected for 6 hours. Urine excretion ratios of lactulose and mannitol (L/M) were measured. L/M ratios of EN group on POD-1, POD 7 and POD 12 were 0.026+/-0.017, 0.059+/-0.026, 0.027+/-0.017, respectively, and those of PN group were 0.025+/-0.013, 0.080+/-0.032, 0.047+/-0.021, respectively. Patients of both groups had elevated L/M ratios on POD 7 vs. POD-1. However the ratio returned toward control level in EN group by POD 12. In contrast, PN group still had elevated L/M ratios on POD 12. L/M ratio increases for a period of time after surgical trauma and the loss of gut mucosal integrity can be reversed by substitution of enteral nutrition.
