Lycium Barbarum Polysaccharides

Abstract Objectives Ulcerative colitis (UC) is a chronic inflammatory disease in the colon, and the prevalence of UC is increasing worldwide. Lycium barbarum polysaccharides (LBP) from wolfberry extract has immunomodulatory effects, and act as a prebiotics candidate. Capsaicin (CAP) as an active ingredient of chili peppers has the potential for anti-inflammation and antioxidation. This study investigated the effects of LBP and CAP on anti-inflammation and antioxidation in rats with dextran sulfate sodium (DSS)-induced UC. Methods Male Sprague-Dawley rats were divided into five groups: control, UC (DSS), UC treated with 100 mg/kg bw LBP (LBP), UC treated with 12 mg/kg bw CAP (CAP), and UC treated with a combination of 50 mg/kg bw LBP and 6 mg/kg bw CAP (MIX) groups. The treatment of LBP and/or CAP was daily given by oral gavage from week 1 to week 4, and UC was induced by 5% DSS in drinking water for 6 days during week 3. Results The DSS group significantly increased disease activity index (DAI) scores, the levels of pro-inflammatory cytokines interleukin-6 (IL-6) in the serum and tumor necrosis factor-α (TNF-α) in the colon, and serum lipid peroxidation malondialdehyde (MDA) levels compared with the control group. While the activities of antioxidant enzymes such as superoxide dismutase (SOD) and catalase (CAT) in the serum were significantly decreased in the DSS group. The LBP, CAP, and MIX groups significantly decreased DAI scores on day 6 during the DSS-induced period. Compared with the DSS group, the LBP group significantly decreased serum IL-6 and serum MDA levels, but increased serum CAT activity. The CAP group significantly decreased serum IL-6 levels. The MIX group significantly reduced serum IL-6 and colon TNF-α levels, but elevated serum SOD activity. Conclusions The results suggest that administration of LBP and/or CAP attenuate DSS-induced UC symptoms in rats through the anti-inflammatory and antioxidant activities.

Inflammatory Effect

Background: Phytoncide is known to have antimicrobial and anti-inflammatory properties. Purpose: This study was carried out to confirm the anti-inflammatory activity of two types of phytoncide extracts from pinecone waste. Methods: We made two types of animal models to evaluate the efficacy, an indomethacin-induced gastroenteritis rat model and a dextran sulfate sodium-induced colitis mouse model. Result: In the gastroenteritis experiment, the expression of induced-nitric oxide synthase (iNOS), a marker for inflammation, decreased in the phytoncide-supplemented groups, and gastric ulcer development was significantly inhibited (p < 0.05). In the colitis experiment, the shortening of the colon length and the iNOS expression were significantly suppressed in the phytoncide-supplemented group (p < 0.05). Conclusions: Through this study, we confirmed that phytoncide can directly inhibit inflammation in digestive organs. Although further research is needed, we conclude that phytoncide has potential anti-inflammatory properties in the digestive tract and can be developed as a functional agent.

Inflammatory Effect

Portulaca oleracea L. is a traditional Chinese medicine, which has been used as adjuvant therapy for inflammatory bowel disease (IBD). However, the mechanism of its activity in IBD still remains unclear. Since previous studies have documented the anti-inflammatory effect of peroxisome proliferator activated receptors-γ (PPAR-γ), Portulaca regulation of PPAR-γ in inflammation was examined in current study. Ulcerative colitis (UC) was generated by 5% dextran sulfate sodium (DSS) in mice and four groups were established as normal control, DSS alone, DSS plus mesalamine, and DSS plus Portulaca. Severity of UC was evaluated by body weight, stool blood form, and length of colorectum. Inflammation was examined by determination of inflammatory cytokines (TNF-a, IL-6, and IL-1a). Portulaca extract was able to attenuate development of UC in DSS model similar to the treatment of mesalazine. Moreover, Portulaca extract inhibited proinflammatory cytokines release and reduced the level of DSS-induced NF-κB phosphorylation. Furthermore, Portulaca extract restored PPAR-γ level, which was reduced by DSS. In addition, Portulaca extract protected DSS induced apoptosis in mice. In conclusion, Portulaca extract can alleviate colitis in mice through regulation of inflammatory reaction, apoptosis, and PPAR-γ level; therefore, Portulaca extract can be a potential candidate for the treatment of IBD.
