Abstract
Gastric ulcer is a common disease with increased prevalence in the aged population. Aged gastric mucosa has increased susceptibility to injury along with nonsteroidal anti-inflammatory drugs use due to impaired mucosal defense and decreased vasodilator release. We investigated whether l-arginine could protect against age-related gastric ulceration induced by indomethacin. Aged and adult male Wistar rats were administered sole and combined treatment of l-arginine and Nω -nitro-l-arginine methyl ester ( l-NAME) before induction of gastric ulceration by indomethacin. The gastroprotective effect of l-arginine was displayed only in adult rats with indomethacin-induced gastric ulceration, as evidenced by a significant decrease in ulcer index, oxidative stress parameters, and mucosal myeloperoxidase activity along with increased mucosal PGE2 levels. Interestingly, the mucosal gene expressions of NF-кB, iNOS, and COX-2 were significantly suppressed by l-arginine pretreatment and aggregated upon pretreatment with l-NAME in both adult and aged rats treated with indomethacin. In conclusion, l-arginine protected the rats' gastric mucosa against indomethacin-induced gastric ulceration, possibly, at least in part, by enhancement of mucosal nitric oxide/PGE2 content along with suppressing gastric inflammation and oxidative stress. This study supposed that the gastroprotective effect of l-arginine depends on aging, and even so, the adoption of a new approach to gastric ulcer treatment for the aged population is warranted.

Int Immunopharmacol 2022; 111:109122. [PMID: 35964411 DOI: 10.1016/j.intimp.2022.109122] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2022] [Revised: 07/27/2022] [Accepted: 07/31/2022] [Indexed: 12/14/2022]
Abstract
As a common disease of the digestive system, chronic gastritis is inflammation of the gastric mucosa caused by various factors. Helicobacter pylori (H. pylori) is one of the main causes of chronic gastritis, which can lead to gastric mucosal damage and gland atrophy, thereby promoting gastrocarcinogenesis. Oxidative stress and the inflammatory response are important mechanisms of H. pylori-induced gastritis. 6'-O-Galloylpaeoniflorin (GPF) is a substance isolated from peony root with antioxidant and anti-inflammatory activities. However, its role and mechanism in the pathogenesis of H. pylori-induced chronic gastritis remain unclear. This study explored the effects of GPF on H. pylori-induced gastric mucosal oxidative stress and inflammation using flow cytometry, western blotting, real-time quantitative PCR, and immunohistochemistry. We found that H. pylori infection increased oxidative stress and expression of inflammatory cytokines in vitro and in vivo and that these outcomes were inhibited by GPF. Furthermore, GPF activated nuclear factor erythroid-related factor-2 (Nrf2) and its downstream target genes in H. pylori-infected GES-1 cells and mice. The anti-inflammatory and antioxidant effects of GPF on H. pylori-infected cells were attenuated by an Nrf2 inhibitor. Taken together, these data suggest that GPF reduces H. pylori-induced gastric mucosa injury by activating Nrf2 signaling and that GPF is a potential candidate for the treatment of H. pylori-associated gastritis.
