[DEVELOPMENT OF FUNCTIONAL AND MORPHOLOGICAL CHANGES OF A PANCREAS DEPENDING ON THE DURATION OF OBSTRUCTIVE
Obstructive cholestasis in dogs causes initial reversible pancreatic swelling within three days, progressing to irreversible damage by 14-16 days. Liver enzyme levels correlate with these pancreatic changes.
Area of Science:
- Gastroenterology
- Pathology
- Animal Models
Context:
- Obstructive cholestasis, a condition involving the blockage of bile flow, can lead to significant pancreatic injury.
- Understanding the timeline of pancreatic damage is crucial for managing this condition.
Purpose:
- To investigate the progression of functional and morphological pancreatic disturbances in response to varying durations of obstructive cholestasis.
- To correlate biochemical markers with histological changes in the pancreas.
Summary:
- This study utilized a canine model to simulate obstructive jaundice, monitoring biochemical markers (bilirubin, AST, ALT, amylase, lipase, glucose) and pancreatic histology over 30 days.
- Results indicated rapid increases in liver enzymes and pancreatic enzymes within three days of bile duct obstruction.
- Morphological changes progressed from reversible swelling to irreversible damage between 14-16 days, correlating with biochemical fluctuations.
Impact:
- Provides a detailed timeline of pancreatic injury in obstructive cholestasis using a relevant animal model.
- Highlights the correlation between biochemical indicators and histological findings, aiding in diagnostic and prognostic assessments.
- Contributes to the understanding of the organism's general response to injury in the context of biliary obstruction.

01:24Chronic 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...

01:27Acute 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:
