Background:

Acute pancreatitis pathogenesis is complex.
Oxygen-derived free radicals and cholecystokinin are implicated.
Current therapeutic strategies require evaluation.

Purpose of the Study:

To review the role of oxygen-derived free radicals and cholecystokinin in acute pancreatitis.
To discuss the efficacy of potential therapeutic agents.
To re-evaluate the validity of animal models.

Main Methods:

Literature review on oxygen-derived free radicals and cholecystokinin in pancreatitis.
Discussion of therapeutic agents like scavengers, CCK-receptor antagonists, and somatostatin.
Analysis of animal models for acute pancreatitis induction.

Main Results:

Evidence suggests a role for free radicals and CCK in pancreatitis.
Scavengers, CCK antagonists, and somatostatin were investigated for therapeutic potential.
The direct cytoprotective effects and model validity are questioned.

Conclusions:

The contribution of free radicals and CCK to pancreatitis needs further clarification.
The efficacy of discussed therapeutic agents in animal models warrants reconsideration.
The suitability of current animal models for studying acute pancreatitis is debatable.
