METHODS: A total of 36 Sprague Dawley rats were divided group A, B, and C, intragastrically treated with edible alcohol (530 ± 20 mL/L), ethanol (530 mL/L), and normal saline at 5 mL/kg once every other day, respectively.

Abstract

AIM: To observe the response to edible alcohol-induced injury and expression of prostaglandin E₂ (PGE₂), transforming growth factor-α (TGF-α) in gastric mucosa of rats.

METHODS: A total of 36 Sprague Dawley rats were divided group A, B, and C, intragastrically treated with edible alcohol (530 ± 20 mL/L), ethanol (530 mL/L), and normal saline at 5 mL/kg once every other day, respectively. The rats were killed at 1 week and 1 month after treatment, and the extent of mucosal injury was evaluated. Immunohistochemistry was used to examine the mucosal expression of TGF-α protein. Anther 36 rats were selected and treated as the method mentioned above, and the level of PGE₂ in gastric mucosa was determined by enzyme linked immunosorbent assay.

RESULTS: The most severe gastric mucosal injury was found in group C, then in group B, and the rats in group A were found with the mildest mucosal injury. The scores for mucosal injury were significantly different among group A, B and C 1 week (26.5 ± 6.4 vs 40.5 ± 8.1 vs 69.3 ± 4.3, all P < 0.05) and 1 month (34.8 ± 8.0 vs 54.8 ± 8.0 vs 74.8 ± 3.1, P < 0.05) after treatment. The level of mucosal PGE₂ was increased significantly in group A and B as compared with that in group C 1 wk after treatment (15.7 ± 1.4, 14.6 ± 1.9 ng/L vs 18.5 ± 2.7 ng/L, P < 0.05), but there was no difference between group A and B. One month after treatment, the level of PGE₂ was decreased in group A, not different from that in group C, but there was obvious difference between the former two groups and group B (15.7 ± 1.4, 14.6 ± 1.9 ng/L vs 18.5 ± 2.7 ng/L, P < 0.05). The expression of TGF-α was significantly lower in group A and B than that in group C 1 week after treatment (both P = 0), but no difference was found between group A and B. TGF-α expression was significantly different among group A, B, and C 1 month after treatment (P = 0.013, 0.001, and 0, respectively). The level of PGE₂ and the expression of TGF-α were notably different between 1 week and 1 month in group A and C, but not in group B.

CONCLUSION: Appropriate stimulus with edible alcohol and ethanol may lead to adaptive cytoprotection in gastric mucosa through up-regulation of PGE₂ and TGF-α.
