The Effects of Systemic Use of Nicotine on the Rat Nasal Mucosa: a Histopathologic and Immunohistochemical Study
The objective of this study was to evaluate the histopathologic effects of systemic use of nicotine on the rat nasal mucosa. Twelve adult Sprague-Dawley rats weighing 180-220 g, were used as experimental animals. The rats were divided into Nicotine and control groups. The rats of Nicotine groups (n=...

Twelve adult Sprague-Dawley rats weighing 180-220 g, were used as experimental animals. The rats were divided into Nicotine and control groups. The rats of Nicotine groups (n=6) were administered 2mg/kg Nicotine sulphate for 28 days. The rats of control group (n=6) were only administered 1,5 ml physiologic saline solution subcutaneously for 28 days.
