were distributed into four groups. One group was used as control, while the rest three were given
Nasswar, water extract of tobacco, Nasswar and water extract of tobacco respectively. The animals
were sacrificed and the stomach were cut and examined for changes after fixing and staining. The
morphological changes produced were mild, while the degenerative changes and inflammatory
infiltration were observed in some animals. In our study we could not see any carcinogenic effect
of tobacco in the stomach Prolong clinical and experimental study should be canned out to determine
