ABSTRACT
Objective To investigate the effect of sleeve gastrectomy on the intestinal barrier of obesity rats fed with high-fat diet.Methods Thirty obesity rats fed with high-fat diet were randomly divided into three groups including common diet group (CD,n=10),sham operation group (SO,n=10) and sleeve gastrectomy group (SG,n=10).The lactulose/mannitol ratios (L/M) in 24-hour urine and endotoxin in portal vein were evaluated four weeks after surgery.The levels of tight junction proteins including claudin-1 and occludin in intestinal mucosa were analyzed by western blot.Results The body weight of SG group was significantly decreased than those of CD group (P<0.001) and SO group (P<0.001) four weeks after surgery.The L/M ratio in 24-hour urine of SG group was significantly lower than those of CD group (P<0.001) and SO group (P<0.01).The endotoxin level in portal vein of SG group was significantly lower than those of CD group (P<0.01) and SO group (P<0.05).The claudin-1 level in intestinal mucosa of SG group was significantly higher than those of CD group (P<0.001) and SO group (P<0.01) four weeks after surgery.The occludin level in intestinal mucosa of SG group was significantly higherthan those of CD group (P<0.001) and SO group (P<0.001).Conclusions Sleeve gastrectomy can reduce body weight,L/M ratio in 24-hour urine and endotoxin level in portal vein of obesity rat fed with high-fat diet and increase the levels of claudin-1 and occludin in intestinal mucosa.
