ABSTRACT
Objective Beagle dogs were subjected to hemorrhagic shock plus resuscitation and endotoxiemia (two-hit) to set up multiple organ dysfunction syndrome (MODS) model. In the study, this model can be used to monitor the responses of organ compensation and in compensation. Method Seven male Beagle dogs, weight ( 15 ± 2) kg, were provided by animal experiment centre of Xinjiang Medical University. MODS model was set up in 7 Beagle dogs. Hemorrhagic shock was produced according to the method of Wigger. After the resuscitation,Escherichia coli endotoxin was given via the femoral vein at a dose of 1.5 mg/kg. The criteria of MODS were defined as the presence of two or more of organ dysfunction. Clinical biochemical values were examined before making model and 0 h,3 h,6 h,9 h, 12 h after the establishment of model. The pathological change of the liver and the kidney were observed under the light microscopy. Results Significant differences of WBC,PaO2,LP,ALT, AST,Cr and BUN were observed after the establishment of model compared with those before the establishment of model ( P < 0.05). Severe pathological lesions were observed in tissues of the liver and kidney. Conclusions Hemorrhagic shock and endotoxemia,a two-hit method, can be used to set up a delayed animal model for MODS to study the responses of organ dysfunction caused by ischemic and infectious diseases.
