BACKGROUND: Lyprinol (Pharmalink International), the stabilised lipid extract of the New Zealand green-lipped mussel, is currently used to relieve symptoms of arthritis. We investigated the effect of pretreatment with Lyprinol (LYP) on experimentally induced inflammatory bowel disease (IBD) in mice.
METHODS: Male C57BL/6 mice (aged 6 weeks) were gavaged daily for 13 days with (150 microl) olive oil (OO; n = 7), fish oil (FO; n = 8), or LYP (n = 8). Mice consumed 2% dextran sulfate sodium (DSS) for 6 days, starting on day 7. Body weight and disease activity index (DAI) scores were recorded daily. Colonic damage was determined by histopathology. Colonic inflammation was quantified by myeloperoxidase (MPO) activity.
RESULTS: LYP treatment significantly (P < 0.05) reduced body weight loss, DAI scores, crypt area losses, and cecum and colon weights, compared with FO treatment. MPO activity was not significantly affected by any treatment.
CONCLUSIONS: These findings provide preliminary evidence that Lyprinol may be potentially useful in ameliorating symptoms of IBD. The benefit, however, is unlikely to be due to the omega-3 fatty acid content. Dose-response evaluation of Lyprinol in experimental IBD is warranted.
