Popis: | To investigate the synergistic activity of infliximab to the therapeutic effectiveness of octreotide in a rat model of acute necrotizing pancreatitis (ANP).Forty Sprague-Dawley rats were randomly divided into sham-operated group (SO), ANP group (ANP), octreotide group (OG), infliximab group (IG), and combination group (CG) (n = 8 in each group). The ANP model was induced by biliopancreatic duct injection with 4.5% of sodium taurocholate solution. Rats of the OG, IG, and CG were given a tail vein injection of octreotide (10 μg/kg), infliximab (8 mg/kg), and infliximab (8 mg/kg), respectively, combined with octreotide (10 μg/kg) at 6 hours after modeling. All rats in each group were killed at 24 hours after modeling. Serum biochemical indicator and partial pressure of arterial oxygen/fraction of inspired oxygen (PaO2/FiO2) of rats were determined. Pathological severity score of organs were evaluated.The serum biochemical indicator and organs' pathology score of OG , IG, and CG were obviously lower than those in the ANP group, and those in the CG were the lowest (P0.05). The PaO2/FiO2 levels in the OG, IG, and CG were significantly higher than that in the ANP group (P0.05).Infliximab could significantly lower the serum biochemical indicator, improve organs' function, and enhance the therapeutic effectiveness of octreotide on ANP. |
