The resultsshowed that the signs of asphyxia were obvious, so were thecongestion and edema of the brain. The spotty and focalhemorrhages in brain stems, multiple myolysis of papillarymuscles and contractionbands necrosis of myocardium wereobserved occasionally. The main clinical symptom of intoxication was freqUunt clinic - tonic convulsions, which weresimilar to the grandma epilepsy. The poisoned died mainly in3 hours. The general poisoning symptoms, LD50, toxicological mechanism and medicolegal expertise were also reviewed.展开更多

The damage in peripheral organs may be more severe than that in the pancreas, and can even lead to multiple organ dysfunction. It is critical to recognize early pathological changes in multiple organs. This study aimed to assess the early pathological features of damaged organs in a rat model of SAP. METHODS: Thirty clean grade healthy male Sprague-Dawley rats weighing 250-300 g were randomly divided into a model control group (n=15) and a sham-operated group (n=15). The SAP rat model was induced by sodium taurocholate. Samples of blood and from multiple organs were collected 3 hours after operation. We assessed the levels of IL-6, TNF-alpha, PLA2, NO, ET-1, MDA, amylases and endotoxin in blood and observed the early pathological changes in multiple damaged organs. RESULTS: Levels of IL-6, TNF-alpha, PLA2, NO, ET-1 and MDA in serum and of amylase and endotoxin in plasma of the model control group rats were significantly higher than those of the sham-operated group (P<0.01). Different degrees of pathological change were observed in multiple damaged organs. CONCLUSION: Multiple organ injury may occur at the early stage of SAP in rats.展开更多
