Pain Controlling and Cytokine-regulating Effects of Lyprinol, a Lipid Extract of Perna canaliculus, in a Rat Adjuvant-Induced Arthritis Model

Using an adjuvant-induced arthritis rat model, we investigated the effects of a lipid extract of Perna canaliculus (Lyprinol) on pain. Radiological examinations, as well as levels of pro- and anti-inflammatory (AI) cytokines, were measured aiming to provide independent objective data to the pain con...

description Using an adjuvant-induced arthritis rat model, we investigated the effects of a lipid extract of Perna canaliculus (Lyprinol) on pain. Radiological examinations, as well as levels of pro- and anti-inflammatory (AI) cytokines, were measured aiming to provide independent objective data to the pain controlling investigation. We confirmed the ability of Lyprinol to control pain at the initial phase of its administration; with similar efficacy to that observed with Naproxen. The pain scores slowly increased again in the group of rats treated with Lyprinol after day 9-14.The Naproxen-treated rats remained pain-free while treated. Both Naproxen and Lyprinol decreased the levels of the pro-inflammatory cytokines TNF-a and IFN-g, and increased that of IL-10. Extra-virgin olive oil was ineffective on cytokine secretion. Rats treated with Lyprinol were apparently cured after 1 year. This study confirms the AI efficacy of this lipid extract of P.canaliculus, its initial analgesic effect, its perfect tolerance and its long-term healing properties.
