Abstract
AIM: To investigate the influence of lactulose and glutamine on the changes of jejunal mucosal morphology of rats with obstructive jaundice.
METHODS: Eighty-four Wistar rats were randomly divided into 4 groups. The rats in group A served as sham operation controls, and those in group B as common bile duct ligation controls. The rats in group C and D were intragastrically treated with lactulose and glutamine, respectively, besides common bile duct ligation. The rats were sacrificed at the 0, 5th and 10th post-treatment day. The morphology of jejunum mucosa was observed and the height of jejunal villi was measured under microscope.
RESULTS: The tela submucosa of jejunum had a few lymphocytes in group A, while that had more lymphocytes in group B, C and D under microscope. The height of jejunal villi in group A was not changed, and it was significantly higher than that in group B (5 d: q = 4.32, P < 0.01; 10 d: q = 11.03, P < 0.01). The height of jejunal villi in group B was obviously lower than that in group C or D, but it was not significantly different between group A and D (5 d: q = 3.62, P > 0.05; 10 d: q = 3. 83, P > 0.05). There was also no marked difference between group C and D (P > 0.05).
CONCLUSION: Common bile duct ligation leads to obstructive jaundice, which results in atrophy of the jejunum mucosa. Both lactulose and glutamine may prevent the atrophy of intestinal mucosa, but their effects are not significantly different.
