Antiulcer and hepatoprotective effects of aqueous extract of Plantago ovata seed on indomethacin-ulcerated rats.
Biomedical Journal 2018 Februrary
BACKGROUND: The objective of the study was to investigate the protective effects of aqueous extract of Plantago ovata seed (AEPOS) on peptic ulcer induced by indomethacin (IND) in rats.
METHODS: Rats (250-300 g) were divided into three groups (5 rats in each group). Gastric ulcer was induced by a single oral gavage of 48 mg/kg IND. The first group received only 5% sodium bicarbonate orally (5 ml/kg) whereas the control (IND) group received only single oral dose of 48 mg/kg IND. The third group was pretreated with an extract (100 mg/kg) for 4 days. At the end of the 4th day, rats were kept fasted for 24 h before administration of IND 48 mg/kg. The rats were sacrificed 4 h after oral administration of IND and their stomach and liver were fixed in formalin (10%) and sections of 5 mm in diameter were prepared. Histological and morphological characteristics of stomach and liver were assessed using hematoxylin and eosin (H&E) staining.
RESULTS: AEPOS (100 mg/kg) showed a significant (p < 0.05) reduction in microscopic and macroscopic ulcer index as compared to the IND group. Histological analysis indicated that AEPOS has hepatoprotective effect and can prevent mucosa damage in stomach.
CONCLUSION: Results revealed that AEPOS has anti-ulcer and hepatoprotective effects.
