Abstract:
Specimens of apocrine and eccrine sweat collected without and after pilocarpine stimulation from smokers and non-smokers exposed to tobacco smoke were investigated for the presence of nicotine. The concentrations were determined by radioimmunoassay, so that the values obtained represent the concentrations of nicotine plus its metabolites, e.g. cotinine. Measurable nicotine concentrations were found in all samples. The levels measured in apocrine sweat were higher than those in eccrine sweat. The presence of unchanged nicotine in sweat was revealed by GC/MS.

Sweat glands are classified as merocrine glands; that is, the secretions are excreted by exocytosis through a duct without affecting the cells of the gland. There...
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...
