ABSTRACT
Aim To study protective effects of ulinastatin on injury of organs in rats induced by endotoxin.Methods 36 Wistar rats were divided into 3 groups: control group,model group and treatment group.The model of injury of organs were induced by injecting lipopolysaccharide(LPS) through the sublingual vein into rats.Ulinastatin was injected into the sublingual vein of rats in treatment group,LPS was injected into rats in the same way after 10 minutes.At the second hour or the sixth hour after treatment,serum and lung,liver and renal samples were cellected from rats to determine levels of TNF-?,IL-6,IL-1?and iNOS by RIA.Pathologic changes of lung,liver and renal organ were examined.Results Levels of TNF-?,IL-6,IL-1?,iNOS of serum and renal organs in treatment group were obviously reduced than those in model group(P
