Summary
Oxygen free radicals play a key role in acute pancreatitis development. Scavenger treatment, even after onset, significantly reduced pancreatic tissue damage and lipid peroxidation.
Area of Science:
- Biochemistry
- Pathology
- Toxicology
Background:
- Acute pancreatitis is a severe inflammatory condition.
- The role of oxidative stress in acute pancreatitis is not fully understood.
Purpose of the Study:
- To investigate the involvement of oxygen free radicals in the pathogenesis of acute pancreatitis.
- To evaluate the therapeutic potential of antioxidant enzymes in mitigating pancreatitis-induced tissue damage.
Main Methods:
- Acute pancreatitis was induced in rats using cerulein infusion.
- Biochemical markers (serum enzymes, lipid peroxidation products) and histological changes were assessed.
- The effects of superoxide dismutase and catalase treatment were examined.
Main Results:
- Cerulein infusion led to increased serum enzymes, lipid peroxidation, and histological signs of pancreatitis, including necrosis and inflammation.
- Antioxidant treatment prevented lipid peroxidation and reduced zymogen degranulation and necrosis.
- Oedema and inflammatory response were not significantly affected by scavenger treatment.
Conclusions:
- Oxygen free radicals are critical mediators in the development of acute pancreatitis.
- Antioxidant therapy can ameliorate specific tissue damage in acute pancreatitis, even when initiated after the disease onset.

01:27Acute Pancreatitis I: Introduction
Pancreatitis is inflammation of the pancreas, an organ located behind the stomach. It can be either acute or chronic.
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:

01:24Chronic Pancreatitis I: Introduction
The pancreas, an elongated and flat gland situated behind the stomach, serves a vital function in digesting food and managing blood sugar levels.
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...

01:25Acute Pancreatitis I: Introduction
Acute pancreatitis is the sudden inflammation of the pancreas caused by the early activation of digestive enzymes, leading to the autodigestion of pancreatic tissue. This results in local inflammation and, in severe cases, systemic complications.EtiologyUnderstanding the underlying causes is crucial, as identifying the etiology guides treatment and anticipates complications. Acute pancreatitis can be triggered by various factors, typically grouped into the following clinical categories.Biliary...
01:21Acute Pancreatitis II: Pathophysiology
The pathophysiology of acute pancreatitis centers on injury to pancreatic acinar cells, which initiates a cascade of harmful intracellular events.This injury leads to premature activation of trypsinogen to trypsin in the pancreas. Trypsin then activates other digestive enzymes, such as chymotrypsin, elastase, and phospholipase A2, which begin breaking down pancreatic tissue. The resulting autodigestion causes local inflammation, tissue swelling, hemorrhage, and fat necrosis.Injured acinar cells...
01:25Chronic Pancreatitis I: Introduction
Chronic pancreatitis is a long-standing, relapsing inflammation of the pancreas, characterized by irreversible damage to the gland. It results in progressive destruction of the pancreatic parenchyma, fibrosis, and eventual loss of both exocrine and endocrine function. The disease may evolve gradually after multiple episodes of acute pancreatitis or develop independently.EtiologyChronic pancreatitis can arise from a variety of causes:Alcohol use is the leading cause, accounting for 70–80% of...
01:21Chronic Pancreatitis II: Pathophysiology
Chronic pancreatitis is a progressive and irreversible inflammation of the pancreas, most often caused by long-term alcohol abuse, but it can also be related to ductal obstruction, smoking, or genetic factors.Chronic pancreatitis occurs when the pancreas is repeatedly exposed to harmful agents like alcohol, smoking, ductal obstruction, or genetic predisposition. These factors lead to the release of toxic metabolites and inflammatory cytokines, sustaining chronic inflammation in the pancreatic...
