SATTAR, ARRANSA et al. Evaluation of Gastro-protective Activity of Myristica fragrans on Ethanol-induced Ulcer in Albino Rats. An. Acad. Bras. Ciênc. [online]. 2019, vol.91, n.2, e20181044.  Epub June 19, 2019. ISSN 0001-3765.  https://doi.org/10.1590/0001-3765201920181044.

Abstract: Myristica fragrans seeds are traditionally used to treat dyspepsia, vomiting and abdominal pain. The purpose of this study was to investigate the protective effect of Myristica fragrans in ethanol induced gastric ulcer. Study was carried out on rats, divided into four groups; negative control, positive control, standard drug control, and Myristica fragrans extract treated rats. The pH, ulcer index, acidity values and histopathological examination of stomach were evaluated. Myristica fragrans significantly (P<0.05) reduced gastric lesions by 41.68% in ethanol induced ulcer model at 200 mg/kg when compared to sucralfate (60.41%). However, histopathological findings appeared similar in Myristica fragrans extract treated and standard drug control groups, where stomachs were found with mild erosion of superficial epithelium and few infiltrated inflammatory cells. pH of gastric contents of rats from extract treated was increased (4.25 ± 0.25) as compared to positive control group (2.25 ± 0.25). Ulcer index of extract treated rats was improved (41.74%). Moreover, total acidity of extract treated group (60.0 ± 0.47) was decreased as compared to control group (74.50 ± 1.04). It is concluded that Myristica fragrans showed significant protecting activity in ethanol induced ulcer. Isolation and purification of phytochemicals responsible for gastroprotective activity becomes necessary.
