Effects of Rhodiola rosea on indomethacin-induced gastric injury

Abstract

Objective:The objective of the present study was to evaluate the effects of Rhodiola rosea in the indomethacin-induced ulcer model in rats and to clarify the underlying mechanisms of action.Methods: Rats in treatment groups were treated with Rhodiola rosea (RR) 14 days. Peptic ulcer was induced by indomethacin (IND) injection (100 mg/kg, p.o.). The groups (n = 6) were designed as; Group I (control); Group II (IND): After 24h of food starvation, rats were given only 100 mg/kg IND by oral gavage to induce gastric mucosal injury. Group III (ESO): Rats were pretreated with 20 mg/kg of ESO for 14 consecutive days by oral gavage. Group IV (RR): Rats were pretreated with 500 mg/kg RR for 14 consecutive days with oral gavage.Results: Rhodiola rosea effectively alleviated indomethacin-induced ulcer via reduction in oxidative stress (decreased MDA and increased SOD, and GSH). Moreover, Rhodiola rosea alleviated indomethacin-induced damage by regulating expressions of COX enzymes, prostaglandin E2, proliferating cell nuclear antigen (PCNA), cell proliferation, apoptosis and regulated the NF-κB signaling pathway. Rhodiola rosea also attenuated inflammatory injury by suppressing TNF-𝛼𝛼, IL-1β, and NF-κB. The caspase-3 expression was also down-regulated in stomach tissues. Conclusions:In conclusion, Rhodiola rosea protected the gastric mucosa from harmful effects of indomethacin and as a natural medicinal herb, Rhodiola rosea might be a potential therapeutic agent for preventing and treating indomethacininduced gastric damage.

Carnosic Acid Ameliorates Indomethacin-Induced Gastric Ulceration in Rats by Alleviating Oxidative Stress and Inflammation

“…The dosage of the tested agents was chosen according to the previous studies [ 33 , 34 ]. Rats were divided into four experimental groups each consisting of seven animals: control (no treatment was applied), IND-ulcerated animals (Gastric ulcer model, 100 mg/kg IND), IND + ESP (20 mg/kg ESP), IND + CA (100 mg/kg CA) [ 33 , 35 ].…”

Gastroprotective effects of bromelain on indomethacin-induced gastric ulcer in rats

“…Bromelain has been accepted as a phytotherapeutic agent due to its safety and minimal side effects. It is also widely used for anti-inflammatory, antioxidant, anticancer activity, and immunomodulatory effects (17). In the present study, the potential gastroprotective effects of BRM against IND-induced gastric ulcers in rats were investigated (5).…”
