The effects of sex hormones on the synthesis of collagen were investigated in rats with alkali-induced corrosive esophageal burns. In 75 rats, a standard esophageal burn was produced as described by Gehanno. The animals were then grouped as follows: controls (group A), animals with pure esophageal burns (group B), and animals with esophageal burns treated with estradiol and progesterone (group C). All animals were killed on the 28th day of the experiment. Hydroxyproline levels were determined, and histopathologic evaluation was performed for each group. The hydroxyproline levels were significantly lower in the rats treated with estradiol and progesterone. Histopathologically, collagen deposition in the submucosa and tunica muscularis was lower in the estradiol/progesterone group than in the group with pure esophageal burns. Based on the results, the authors believe that estradiol and progesterone inhibited new collagen synthesis, and therefore, alkali-induced esophageal stricture formation.
