Studying Effects of Cigarette Smoke on Pseudomonas Infection in Lung Epithelial Cells
Published on: May 11, 2020
Abstract:
Knowledge about the harmful effects of smoking on the lungs is high among the general population. This damage can occur to both active and passive smokers. Although scientific understanding in this area is incomplete we do have some knowledge about how individual toxic substances in cigarette smoke act on the lung tissues. There is great variation in smokers' susceptibility to the harmful effects of tobacco dependence. The reasons for this are complex and the role of genetic factors requires more research.

Drugs Acting on Autonomic Ganglia: Stimulants
Ganglionic stimulants activate NM nicotinic receptors in autonomic ganglia, falling into two categories: nicotine mimetics [e.g., lobeline, dimethylpiperazine, tetramethylammonium] and muscarinic receptor agonists [e.g., muscarine, methacholine]. The first category's action is rapid and blocked by nicotinic receptor antagonists, while the second category's action is delayed and blocked by atropine-like agents. Nicotine, an alkaloid, affects the heart rate by stimulating sympathetic or...
