The influence of some neuroleptic, adreno, sympatho- and cholinolytic substances on the development of experimental brain edema induced with nicotine was studied in tests conducted on rats. It was ascertained that marked antiedemic properties display drugs blocking the alpha-adrenoreceptors
We have previously shown that nicotine, the addictive component of tobacco products, alters the blood-brain barrier (BBB) Na(+),K(+),2Cl(-) cotransporter (NKCC) during in vitro hypoxia-aglycemia exposure. Attenuation of abluminal NKCC suggests that accumulation of ions in the brain extracellular
More than 1 billion world's population actively smokes tobacco containing the bioactive component nicotine (NT). The biological role of this molecule is mediated through the activation of nicotinic cholinergic receptors, widely distributed in various human tissues including retinal pigmented
Benzo(a)pyrene (B(a)P) is a well-known environmental contaminant and carcinogen. Its sources include tobacco smoke, automobile exhaust, forest fire, and other combustion processes. Farnesol, an active principle of Vachellia farnesiana and other aromatic plants, possesses preventive properties
OBJECTIVE
Cigarette smoke contains over 4000 chemicals including well-characterized toxicants and carcinogens, among which is cotinine. Cotinine is the principal metabolite of nicotine that has adverse affects on the microcirculation via vasoconstriction, hypoxia and the wound-healing cascade. Its
OBJECTIVE
To compare the efficacy and safety of 22-mg and 44-mg doses of transdermal nicotine therapy when it is paired with minimal, individual, or group counseling to improve smoking cessation rates.
METHODS
An 8-week clinical trial (4 weeks double-blind followed by 4 weeks open label) using
Complex regional pain syndrome (CRPS) is defined as an extreme and chronic pain condition, and photobiomodulation has relevance as a complementary treatment for CRPS. The objective of this study was to verify the effects of photobiomodulation (PBMT) therapy protocols at two wavelengths Histopathological changes in the brains of embryos from female rats treated with nicotine during pregnancy and possible involvement of nitric oxide (NO) and catecholamines in the nicotine-induced abnormalities of developing brain were investigated. Sexually mature female Wistar rats were given 1, 2,
This study was designed to investigate the possible protective actions of nicotine on cerebrovascular permeability in convulsions during nicotine-induced seizures. We have measured the permeability changes in the blood-brain barrier (BBB) macroscopically and spectrophotometrically by using Evans
Clinical studies indicate that cigarette smoking increases the risk for developing acute pancreatitis. The nicotine metabolite 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK) is a major cigarette smoke toxin. We hypothesized that NNK could sensitize to pancreatitis and examined its effects in
OBJECTIVE
The effects of passive smoking on the voice and laryngeal structures of 20 female passive smokers and 20 age-matched nonsmokers were examined.
METHODS
The voice evaluation consisted of acoustic, aerodynamic, and videostroboscopic analyses.
RESULTS
Three passive smokers displayed mild edema
Activation of the cholinergic anti-inflammatory pathway through direct activation of nicotinic acetylcholine receptors on immune cells can inhibit pro-inflammatory chemokine and cytokine release and thereby protect in a variety of inflammatory diseases. The aim of this study was to investigate
Background: The use of electronic cigarettes (e-cigarettes) is very common worldwide. To date, an increase of nicotine intoxication following an accidental or intentional ingestion/injection of refill solution (e-liquid) has been
