摘　　要：Objective: To explore the changes of plasma endothelin(ET) and nitric oxide (NO) levels in patients with a-cute pancreatitis.Methods: The level of plasma ET was measured by ra-dioactive-immunoassay, and NO by spectrophotometry.Results: The levels of ET, NO and the ET/NO ratioin patients with severe acute pancreatitis(SAP) within24 hours in hospital were all significantly higher thanthose in other groups of patients [(176±8)pg/ml,(97±11) μmol/L, and 1.83±0.12, P<0.01]. Com-pared to healthy controls(N), the levels of ET and NOin patients without pancreatitis acute abdomen (NAP)and patients with mild acute pancreatitis (MAP) in-creased significantly (P<0.01). After appropriate treat-ment, the levels of ET and NO in the MAP groupwere lower (P<0.01). Compared with those beforetreatment, the levels of ET and NO in the SAP groupon the 3rd and 7th day in hospital dropped signifi-cantly(P<0.01).The ET/NO ratio on the 7th daywas also lower than that on admission (P<0.01).Conclusions: The malfunction of endothelial cells andthe increased ET/NO ratio may be related to the mecha-nism of pancreatic microcirculatory disturbance in pa-tients with SAP; early dynamic determination of theseparameters may help predict the prognosis of SAP.Objective: To explore the changes of plasma endothelin(ET) and nitric oxide (NO) levels in patients with a-cute pancreatitis.Methods: The level of plasma ET was measured by ra-dioactive-immunoassay, and NO by spectrophotometry.Results: The levels of ET, NO and the ET/NO ratioin patients with severe acute pancreatitis(SAP) within24 hours in hospital were all significantly higher thanthose in other groups of patients [(176±8)pg/ml,(97±11) μmol/L, and 1.83±0.12, P<0.01].
