ABSTRACT:This study was to find the probable effect of Nicotiana tabacum (snuff) on the histological features of the pancreas of adult wistar rats. Nicotiana tabacum is a product of smokeless tobacco which contains many toxins and high levels of nicotine. Twenty male wistar rats weighing 200-210g were used for this study. The control group received distilled water, while the experimental groups received 0.4mg/ml to 0.8mg/ml of snuff solution respectively for 6 weeks, orally with the aid of orogastric tube. Behavioral changes observed includes; polydipsia, polyuria, rapid discharge of faecal droppings, tremor, restlessness, and hyperpnoea. These observations were more intense the in group of animals that received 0.80mg/ml of snuff solution. Histological changes showed degeneration, vacuolation and necrosis of pancreatic acinar cells, hyperplasia of islet of Langerhans in the group that received 0.8mg/ml of snuff. These changes may be attributed to one or more constituents of snuff such as nicotine which has cytotoxic activity.
