OBJECTIVES: Ulcerative colitis (UC) is a common gastrointestinal (GI) disorder characterized by chronic inflammation. Current treatments primarily focus on symptom management, but they have inherent limitations. Global attention is increasingly directed towards exploring herbal remedies as complementary approaches. This study aims to investigate the effects of the hydroalcoholic extract of jujuba on an experimental model of ulcerative colitis.
METHODS: In this study, 15 male BALB/c mice were divided into three experimental groups. The first group served as the untreated UC model, acting as the positive control (PC). The second group received treatment with the hydroalcoholic extract of Ziziphus jujuba, while the third group was treated with mesalamine. UC was induced by injecting 100 μL of 4 % acetic acid (AA) intra-rectally several times. Treatment commenced after the onset of symptoms such as diarrhea and bloody stools. The mice were eventually euthanized ethically, and their spleen and intestinal tissues were collected for analysis. Evaluations included the Disease Activity Index (DAI), myeloperoxidase activity (MPO), nitric oxide (NO) levels, cytokine levels (IL-1β, IL-6, TNF-α), and gene expression (iNOS, COX-2, and cytokines).
RESULTS: The hydroalcoholic extract of the jujuba plant significantly reduced MPO, NO, the DAI, and the production and expression of inflammatory cytokines, as well as the genes iNOS and COX-2, in the group receiving this extract compared to the positive control group (p<0.05).
CONCLUSIONS: The study demonstrates that the hydroalcoholic extract of Ziziphus jujuba significantly reduces inflammation markers such as TNF-α, NO, MPO, IL-1β, and IL-6 in a mouse model of ulcerative colitis. Additionally, it downregulates the expression of pro-inflammatory genes, including iNOS and COX-2. These findings suggest that Z. jujuba extract has potential as an effective anti-inflammatory treatment for managing ulcerative colitis symptoms.
