【Abstract】 Objective: To measure the expression of intestinal iNOS (inducible nitric oxide synthase) mRNA in the intestines of portal hypertension rats. Methods: The intestinal tissues were taken out and were measured by iNOS cDNA in situ hybridization 10 days after the portal hypertension models were made. Results: The results showed that the expression of intestinal iNOS mRNA in the test group is significantly higher than that in the control group. There was significant difference between the two groups (P<0.05). Conclusion: The increase of the expression iNOS mRNA leads to the great production of NO, resulting in the dysfunction of the intestinal movement and the overgrowth of bacteria. It can cause enteremia, edema and the increase of permeability. All the above may result in the bacterial translocation.更多还原
