Abstract
Abstract
Gastric ulcer is a common health issue. Cotinus coggygria heartwood extracts rich in the flavonoids fustin and sulfuretin have shown protective effects in a rat model of indomethacin-induced gastric ulceration. Fustin itself has been protective in a rat model of ethanol-induced gastric ulcer. In the present study we aimed to reveal the effect of the flavonoid fustin isolated from Cotinus coggygria heartwood in a rat model of indomethacin-induced gastric ulceration.
Fustin was isolated from Cotinus coggygria heartwood and purified. The experiment was performed on 30 male Wistar rats allocated to three groups – Control, Indo and F10. F10 group was pretreated with fustin (10 mg/kg b.w. for 7 days). Rats were sacrificed and macroscopic, histopathological and immunohistochemical investigations of the stomachs were performed.
Indomethacin caused severe mucosal damage, proven by the macroscopic, microscopic and immunohistochemical gastric mucosa investigation. Fustin pretreatment slightly reduced the macroscopic indices for gastric damage (ulcer number, area, score and index), and significantly alleviated the severity of the microscopic indices (mucosal erosions, necrosis, hemorrhages and inflammation). In fustin-pretreated rats, the expression of NF-κB was reduced in comparison with indomethacin-treated animals.
In conclusion, fustin exerted a gastroprotective action in an indomethacin-induced gastric ulceration model, probably due to its anti-inflammatory activity.
