Objective:
To explore the changes of plasma endothelin (ET) and nitric oxide (NO) levels in patients with acute pancreatitis.
Methods:
The level of plasma ET was measured by radioactive-immunoassay, and NO by spectrophotometry.
Results:
The levels of ET, NO and the ET/NO ratio in patients with severe acute pancreatitis (SAP) within 24 hours in hospital were all significantly higher than those in other groups of patients [(176+/-8) pg/ml, (97+/-11) micromol/L, and 1.83+/-0.12, P<0.01]. Compared to healthy controls (N), the levels of ET and NO in patients without pancreatitis acute abdomen (NAP) and patients with mild acute pancreatitis (MAP) increased significantly (P<0.01). After appropriate treatment, the levels of ET and NO in the MAP group were lower (P<0.01). Compared with those before treatment, the levels of ET and NO in the SAP group on the 3rd and 7th day in hospital dropped significantly (P<0.01). The ET/NO ratio on the 7th day was also lower than that on admission (P<0.01).
Conclusions:
The malfunction of endothelial cells and the increased ET/NO ratio may be related to the mechanism of pancreatic microcirculatory disturbance in patients with SAP; early dynamic determination of these parameters may help predict the prognosis of SAP.

Acute Pancreatitis I: Introduction
Acute Pancreatitis I: Introduction
Acute pancreatitis is characterized by rapid inflammation of the pancreas, often caused by factors like gallstone blockage or excessive alcohol consumption. Chronic pancreatitis, on the other hand, is a slow, progressive inflammation that may result from long-term alcohol abuse, obstructions in the pancreatic duct, or genetic factors.
The causes of acute pancreatitis include:

Chronic Pancreatitis I: Introduction
Chronic Pancreatitis I: Introduction
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...
