Nicotine-Induced Antinociception in Male and Female Sprague-Dawley Rats
Abstract
Nicotine is a key pharmacologically-active ingredient in tobacco that has cognitive and behavioral effects, including antinociception. The present research examined effects of nicotine as an anti-nociceptive agent in male and female Sprague-Dawley rats. Nicotine was administered subcutaneously (SC) to 145 male and female Sprague-Dawley rats. Behavioral measures of nociception included tail-flick, hot-plate, and cold-flick. The Formalin test, a model for persistent pain, was used to examine nicotine-induced antinociception. After antinociceptive testing, animals were sacrificed and blood was collected and assayed for plasma 17-(3-estradiol (in females). testosterone (in males), plasma nicotine and cotinine brain and spinal cord nicotine and cotinine levels.
