  • Changes in Level of Myelin Basic Protein,TNF-α and IL-6, and Their Correlative Study in Experimental Rat of Pancreatic Encephalopathy

    ObjectiveTo discuss the changes of myelin basic protein (MBP), tumor necrosis factor-α (TNF-α), and interleukin-6 (IL-6) in serum and cerebrospinal fluid of experimental pancreatic encephalopathy rat model, analyze the relationship between each factor and the occurrence and development of pancreatic encephalopathy, and to provide the experimental basis for clinical diagnosis and treatment of pancreatic encephalopathy. MethodsSelecting 40 SD rats were randomly divided into sham operation group (SO group, n=10) and pancreatic encephalopathy group (PE group, n=30), respectively by the duodenal papilla retrograde pancreatic puncture injection of saline solution or 5% sodium taurocholic acid induced rat pancreatic encephalopathy model were set up. The rats in SO group were sacrificed on 1 d, and the PE group were sacrificed ten rats on 1 d, 3 d, and 7 d, respectively after surgery. The brain and pancreatic tissues of rats in each group were taken to observe the pathological changes of the rats and the brain white blood cells within microvessels gathered and coanda phenomenon. The water content of brain tissues, and the contents of MBP, TNF-α and TL-6 in serum and cerebrospinal fluid were detected. ResultsThe changes of brain nerve cell edema and nerve fiber demyelination were obvious in PE group rats after surgery with the extension of time. The contents of MBP, TNF-α and TL-6 in serum and cerebrospinal fluid on 1 d, 3 d, and 7 d after surgery in PE group were significantly higher than that SO group (P<0.05), and gradually increased with the extension of time. But by two two compared, the change trend of the above three indicators were different. ConclusionsMBP, TNF, and IL-6 on the occurrence and development of brain damage of pancreatic encephalopathy play a synergistic effect. To detecte the MBP, TNF-a, and IL-6 content in blood and cerebrospinal fluid could be diagnosed and evaluated the pancreatic encephalopathy.
