Abstract:
In this study, histopathological and immunohistochemical evaluations were made on the damage to the gastric tissue in the gastric peptic ulcer model induced by indomethacin, and it was investigated whether the plants Hypericum perforatum and Rosa spinosissima have a therapeutic effect. In order to create an ulcer model, 25mg/kg indomethacin was administered orally to the rats in the other groups, except the sham control group, in 2 doses, 24 hours apart. In the treatment groups, the first dose of indomethacin was given an hour after the second dose, and the second dose of plant oils was given orally 24 hours later. Then, 1 hour later, the rats were sacrificed. In the histopathological evaluation, sections belonging to the indomethacin control group showed intense degeneration of both epithelial and mucosal glands in the gastric mucosa. Edema and bleeding were also present in the lamina propria and submucosa layers. These observed damages were significantly reduced in the RS+HP-1 and RS+HP-2 groups. As a result of the immunohistochemical evaluations, it was observed that the group with the highest Bax immunoreactivity was the indomethacin control group, and the groups with the lowest were RS+HP-1 and RS+HP-2. It was determined that the group with the lowest Bcl-2 immunoreactivity was the indomethacin control group, and the groups with the highest were RS+HP-1 and RS+HP-2. The results showed that Hypericum perforatum and Rosa spinosissima plants have therapeutic and anti-apoptotic effects on gastric injury.
