ABSTRACT

 

Objective: To observe and evaluate the structural changes in the stomach of the offsprings of Swiss albino mice

exposed to smokeless tobacco during pregnancy.

Study Design: Observational / descriptive study.

 

Place and Duration of Study: This study was conducted at the Animal House of Al-TibriMedical College Karachi from July 2015 to December 2015.

 

Materials and Methods: Female albino mice were mated. After confirmation of pregnancy 20 pregnant mice were divided into two groups of 10 each. Group A experimental was given 5% tobacco of local brand mixed with their normal chow diet along with clean water ad libitum and group B control was given normal diet along with clean water ad libitum. After 2 weeks of birth, 20 offsprings (10 male and 10 female) were selected randomly from both groups. The offsprings were sacrificed by cervical dislocation and their stomachs were removed for gross and histological analysis.

 

Results: The mean weight of stomach in experimental male offspring was found to be 0.12±0.01 grams, while in control group it was 0.18±0.02 grams. Whereas the mean weight of st mach in ex erimental female was found to be 0.10±0.02. However in control female group it was observed as 0.15±0.02 grams. The difference in the mean weight of stomach between the experimental and control groups was bserved to be highly significance (p Value < 0.001) in both male and female offspring. The infection induce marked changes in the stomach, like destruction of

 

gastric folds and glands, desquamation of endothelial

ells of glands.  Mild to moderate inflammatory and chronic

necrotic changes with gastric atrophy were observed

n m

ros opic findings of the gastric mucosa in smokeless

tobacco treated animals. Mild dysplasia and adenomatous

hanges were seen in few cases of experimental animals.

This lesion may result from the oral administration of tox

rr tants.

 

Conclusion: The use of smokeless tobacco duri

g preg a cy has some

adverse outcomes on the offspring of mice

manifested  by the  decrease  in stomach  weight

as  well  as  alter   the

histological  features  of stomach  mucosa

         

 

especially produces the fatty infiltration, nec tic and adenomatous changes of the gastric glands. Key Words: smokeless tobacco, stomach, ffsp ing
