In order to investigate the mechanism of enterogenous infection, sixty SD rats were randomly allocated into four groups∶ group of intestinal obstruction; group of cyclophosphamide+intestinal obstruction; group of cyclophosphamide and group of sham-operation. Each group included 15 rats. Twenty four hours after obstruction of the terminal ileum, the bacteria in blood of portal vein, blood of heart, peritoneal fluid, mesenteric lymph node (MLN) and content of gut were determined quantitatively, the concentration of endotoxin in portal system were measured. The results showed that early (24 hours) intestinal obstruction led to endotoxemia in portal vein, overgrowth of enteric G-bacili and bacterial translocation into the MLN. The immunosuppressive agent cyclophosphamide not only increased the rate of bacterial translocation into MLN and the number of living bacteria in MLN, but also promoted bacteria to spread into the systemic circulation. The authors conclude that under immunosuppression the bacterial translocation from gut by way of lymphatic channel plays an important role in enterogenous infection.
