Özet
We aimed to determine the effects of ethanol extract of Hippophae rhamnoides L. leaves on indomethacin-induced gastric ulcer in rats. 35 male Sprague Dawley rats were divided into 7 groups (n=5) at random: healthy; Hippophae rhamnoides L. leaves ethanol extract (HR) III; indomethacin; indomethacin+famotidine; indomethacin+HRI (100 mg/kg); indomethacin +HRII (250 mg/kg) and indomethacin +HRIII (500 mg/kg). All rats except the healthy group fasted for 24 hours. At the end of this period, HR and famotidine (20 mg/kg) were administered by oral gavage to the corresponding rat groups. Five minutes after the HR treatments, 25 mg/kg of indomethacin was applied by oral gavage to all groups except the Healthy and HR III groups. Six hours after indomethacin administration, stomach tissues were removed for investigation macroscopic and biochemically (Superoxide dismutase activity, Glutathione, and Malondialdehyde levels). HR administration improved ulcerative injury in stomach tissues caused by the indomethacin-induced gastric ulcer. HR administration reduced indomethacin-induced ulcer areas. Moreover, HR treatment significantly decreased malondialdehyde levels, increased glutathione levels, and elevated superoxide dismutase activity. HR significantly improved gastric ulcer by alleviating oxidative stress that could be important in ulcer. HR may be a new potential treatment option for ulcer treatment with an antioxidant effect. These findings may provide a mechanistic basis for using HR leaves to treat gastric ulcer.
