OBJECTIVES: This study aims to examine the acute effect of vitamin E on salivary gland of radioactive iodine (RAI; 131I)-induced rats and to evaluate whether vitamin E have a radioprotective effect.
MATERIALS AND METHODS: Sixteen Wistar albino rats were used in the study. The rats were divided into two groups. The first group was administered (131)I orally and 1 ml physiological saline. The second group was administered (131)I and 1 ml vitamin E intraperitoneally. Vitamin E was started two days before the RAI therapy and continued for seven days. On the eighth day, salivary glands were removed and evaluated histopathologically.
RESULTS: There was no statistically significant difference between the groups. The changes in the interstitial space of all glands and in acinar epithelial cells of parotid and sublingual glands were observed in a lower number of the rats of vitamin E group, compared to the controls. Except panacinar inflammation, histopathological changes in acinar epithelial cells of the submandibular gland were noticed in a lower number of the rats of vitamin E group.
CONCLUSION: Considering the changes in the interstitial space and acinar epithelial cells in a lower number of the rats of vitamin E group, we conclude that vitamin E may have protective effects for interstitial space of all glands and acinar epithelial cells of the parotid and sublingual glands during the acute period.
