Does vitamin E prevent tubal damage caused by smoking? A light microscopy and animal study

Objective: To assess the histomorphological effects of smoking on the cilia of fallopian tubes in mice and the effect of vitamin E on the negative effects of smoke. Study design: Eighteen 12-14 week-old Swiss albino type female mice were randomly divided into three groups, each consisting of six mice: Group A: control group; Group B: mice exposed to cigarette smoke; Group C: mice exposed to cigarette smoke together with vitamin E. Groups B and C were exposed to cigarette smoke for 10 weeks. After 10 weeks, tubal excision was performed in all animals. Histopathologic examination of excised tubal tissue was conducted under light microscopy. Results: The number of cilia was significantly lower in Group B. Although not statistically significant, the median number of cilia in Group C was measured to be higher than in Group B but lower than in Group A. Conclusion: Based on the results, it can be concluded that smoking decreases tubal cilia numbers. Supplementation by vitamin E may treat or at least help to slow down the decrease in number of cilia caused by smoking; therefore it could be used therapeutically in the treatment of smoking-related tubal damage.
