Study results come in the web version of Neuropsychopharmacology. Nicotine is the primary chemical in cigarette smoke that triggers addiction, yet when tested in pet studies, the draw of nicotine alone appears to be relatively weak compared to other abused drugs. Amazed by this phenomenon, UCI researchers conducted a series of research in rodents to determine whether nicotine may connect to some of the other 4,000 components of tobacco smoke to improve addictiveness. Adolescent and adult male rats had been tested in a procedure where each nose poke by the rodents shipped acetaldehyde or nicotine, a combined mix of both drugs, or saline. Adolescent animals quickly discovered to self-administer the nicotine-acetaldehyde combination significantly more than saline or either medication alone.One year after medical procedures, none of those who got Botox had the rhythm issue, versus 27 % of these given saline. Complications from surgery were similar in both combined groups. The Botox recipients reported no drug-specific problems, the researchers reported. Steinberg said 1 injection may possibly be enough. ‘Atrial fibrillation that occurs after cardiac medical procedures is a short-term issue, that is, about one week, so a single injection ought to be sufficient,’ he said.
