1Department of Internal Medicine, Volos General Hospital, Volos, Greece.
Background:
A variety of organisms produce potent toxins that impact human health through compromising respiratory function.
Case Report:
We describe a rare case of abrupt respiratory failure afterNicotiana glaucaingestion in a previously healthy sixty years old female patient. She presented complaining for gait instability and malaise after ingestion of cooked leaves of the wild plant and two hours after the onset she developed respiratory failurefor which she was intubated and mechanically ventilated for two days. The patient fully recovered and was discharged from the hospital.
Conclusion:
Anabasine, the plant's main active ingredient, can cause severe systemic intoxication due to its nicotinic receptor agonist action with respiratory muscle paralysis being the main effect.

Acute Respiratory Failure-I
Definition: It is defined by specific criteria based on blood gas measurements. Hypoxemia happens when the partial pressure of oxygen (PaO2) falls below 60 mmHg. At the same time,...
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...
