Abstract

Non-steroid anti-inflammatory drugs (NSAIDs) have widely been used in patients but side-effects associated with NSAID are also common. Tarantula cubensisextract (TCE) is an antiphlogistic, demarcative, homeopathic and necrotizing drug with wound healing effects in farm animals. However, the therapeutic effects ofTCEon gastric ulcers has not been investigated. The aim of this study was to investigate the gastroprotective effects of TCE against indomethacin-induced gastric injury in rats. A total of 28 female, Wistar albino rats were divided into four groups: (i) the control group, (ii) the indomethacin (Indo) group, (iii) the TCE + Indo group, and (iv) the ranitidine + Indo group. We measured total antioxidant capacity, total oxidant capacity and oxidative stress index in the blood serum. We also measured tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), IL-6, IL-8, and cyclooxygenase-2 (COX-2) activity level in the stomach tissue ofrats. Finally, histopathology of the tissue of all groups was assessed. Immunostaining of 8-hydroxydeoxyguanosine (8-OHdG) and nuclear factor kappa B (NF-kB) was performed in the gastric tissue of all animals studied.Application of the TCE significantly decreased IL-1β and IL-6 levels were markedly lower than ranitidine. Thus, notableIndo-induced alterations in cytokines (IL-1β, IL-6) in rat gastric tissue were alleviated by TCE.Moreover, the gastric mucosal tissues of the TCEtreated group exhibited aregular and uninterrupted mucosal layer and epithelial layer. Immunohistochemical results revealed that Indo increased 8-OHdG and NF-kB expression when compared to the control groups and treatment by TCE decreased the expression. The results obtained showed that the group receiving TCEexhibited lower gastric erosion and better efficiency than with ranitidine. These results have demonstrated that TCEprovides a therapeutic effect in Indo-induced gastric ulcers in rats.
