Intestinal permeability assessed by 51Cr-EDTA in rats with CCl4 - induced cirrhosis

CONTEXT: The straight relationship between cirrhosis and impaired intestinal barrier has not been elucidated yet. OBJECTIVES: To verify 51Cr-EDTA-intestinal permeability in rats with CCl4-induced cirrhosis and controls. METHOD: Fifty male Wistar rats weighing 150-180 g were separated in three groups: 25 animals received CCl4 0.25 mL/kg with olive oil by gavage with 12 g/rat/day food restriction for 10 weeks (CCl4-induced cirrhosis); 12 received the same food restriction for 10 weeks (CCl4-non exposed). Other 13 rats received indomethacin 15 mg/kg by gavage as positive control of intestinal inflammation. RESULTS: The median (25-75 interquartile range) 51Cr-EDTA-IP values of cirrhotic and CCl4-non exposed rats were 0.90% (0.63-1.79) and 0.90% (0.60-1.52) respectively, without significant difference (P = 0.65). Animals from indomethacin group showed 51Cr-EDTA-IP, median 7.3% (5.1-14.7), significantly higher than cirrhotic and CCl4-non exposed rats (P<0.001). CONCLUSION: This study showed the lack of difference between 51Cr-EDTA-intestinal permeability in rats with and without cirrhosis. Further studies are necessary to better clarify the relationship between intestinal permeability and cirrhosis.
