Isolation of Mouse Respiratory Epithelial Cells and Exposure to Experimental Cigarette Smoke at Air Liquid Interface
Published on: February 21, 2011
Summary
Cigarette smoking chronically reduces gastric secretion and increases bile salt reflux. Acute smoking further impairs gastric emptying and increases bile salt reflux, potentially contributing to gastric ulcers.
Area of Science:
- Gastroenterology
- Physiology
- Toxicology
Background:
- Cigarette smoking is prevalent globally.
- Smoking is associated with gastrointestinal disorders, including peptic ulcers.
- The specific effects of smoking on gastric function require further elucidation.
Purpose of the Study:
- To investigate the chronic and acute effects of cigarette smoking on gastric emptying, gastric secretion, and bile salt reflux.
- To compare gastric function in habitual smokers versus non-smokers.
- To explore the potential role of bile salt reflux in smoking-related gastric pathology.
Main Methods:
- Comparative study involving healthy habitual cigarette smokers and non-smokers.
- Assessment of gastric emptying, secretion, and bile salt reflux in fasting and postprandial states.
- Within-subject comparison of smokers while smoking versus not smoking.
Main Results:
- Smokers exhibited lower basal gastric secretion rates than non-smokers, irrespective of smoking status.
- Habitual smokers had significantly higher bile salt reflux and postprandial gastric bile salt concentrations compared to non-smokers, even when not actively smoking.
- Acute smoking led to delayed gastric emptying and increased bile salt reflux and gastric bile salt concentrations.
Conclusions:
- Cigarette smoking exerts both chronic and acute detrimental effects on gastric function.
- Elevated bile salt reflux in smokers may be a key factor in the increased incidence and reduced healing rates of gastric ulcers.
- Findings highlight the impact of smoking on upper gastrointestinal physiology.

01:29Gastroesophageal Reflux Disease I: Meaning and Pathophysiology
Gastroesophageal Reflux Disease (GERD) involves the recurrent backflow of the stomach or duodenal contents into the esophagus, leading to troublesome symptoms and potential esophageal mucosal damage. Although GERD is often referred to as a disease, it is more accurately described as a syndrome, as it encompasses a range of symptoms and complications rather than a singular pathological entity, impacting a large number of individuals as the most prevalent upper gastrointestinal problem. Roughly...

01:21Barrett Esophagus-I: Introduction
Barrett's esophagus is a medical condition where the esophageal mucosa is significantly damaged by stomach acid or other digestive fluids, often due to long-term exposure associated with gastroesophageal reflux disease (GERD). In GERD, a weakened or abnormally relaxed lower esophageal sphincter allows stomach acid to flow persistently into the esophagus.
This constant acid exposure transforms the esophagus's pink mucosal lining (stratified squamous epithelium) into a type of lining more similar...

01:24Chronic Obstructive Pulmonary Disease III: Chronic Bronchitis Features
Chronic bronchitis is a key phenotype of chronic obstructive pulmonary disease (COPD), characterized by airway-centered inflammation and mucus overproduction. It develops from long-term exposure to harmful particles or gases, most commonly cigarette smoke, which triggers a persistent inflammatory response.Cellular and Structural ChangesInflammation initially affects the large bronchi and later the smaller airways, with infiltration by immune cells, including neutrophils, macrophages, and...
01:25Gastroesophageal Reflux Disease
Gastroesophageal reflux disease (GERD) is the backward flow of stomach contents (acid, pepsin, or bile) into the esophagus, causing mucosal inflammation known as esophagitis. It results from failure of antireflux mechanisms, mainly the lower esophageal sphincter (LES), influenced by mechanical and physiological factors.Etiology and Risk FactorsGERD develops when LES function is weakened or when intra-abdominal pressure increases. Risk factors include aging, obesity, and sliding hiatal hernia,...
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...
