Abstract

A lipid-rich extract, prepared by supercritical fluid (CO2) extraction of freeze-dried stabilized NZ green-lipped mussel powder (Lyprinol) has shown significant anti-inflammatory (AI) activity when given to animals and humans. When treated p.o. with Lyprinol, Wistar and Dark Agouti rats developed neither adjuvant-induced polyarthritis or collagen(II)-induced auto-allergic arthritis. This was achieved with doses < NSAIDs, and 200 times < of other seed or fish oils. Lyprinol subfractions inhibited LTB4 biosynthesis by PMN in vitro, and PGE2 production by activated macrophages. Much of this AI activity was associated with omega-3 PUFAs and natural antioxidants [e.g. carotenoids]. In contrast to NSAIDs, Lyprinol is non-gastro toxic in disease-stressed rats at 300 mg/kg p.o., and does not affect platelet aggregation [human, rat]. Clinical studies, either controlled or randomized, have demonstrated very significant AI activity in patients with osteoarthritis (OA), rheumatoid arthritis (RA), asthma, and other inflammatory conditions. Lyprinol is a reproducible, stable source of bioactive lipids with much greater potency than plant/marine oils currently used as nutritional supplements to ameliorate signs of inflammation.

摘要

一种通过超临界流体(二氧化碳)萃取冻干稳定的新西兰绿唇贻贝粉(Lyprinol)制备的富含脂质的提取物,在给予动物和人类时已显示出显著的抗炎(AI)活性。当用Lyprinol口服治疗时,Wistar大鼠和深色刺豚鼠既未发生佐剂诱导的多关节炎,也未发生胶原(II)诱导的自身过敏性关节炎。这是通过低于非甾体抗炎药(NSAIDs)的剂量以及低于其他种子或鱼油200倍的剂量实现的。Lyprinol亚组分在体外抑制中性粒细胞产生白三烯B4(LTB4)以及活化巨噬细胞产生前列腺素E2(PGE2)。这种抗炎活性大多与ω-3多不饱和脂肪酸(PUFAs)和天然抗氧化剂(如类胡萝卜素)有关。与NSAIDs不同,Lyprinol在以300mg/kg口服给药时,对疾病应激的大鼠无胃肠道毒性,并且不影响血小板聚集(在人类和大鼠中)。对照或随机的临床研究已证明,Lyprinol在骨关节炎(OA)、类风湿关节炎(RA)、哮喘和其他炎症性疾病患者中具有非常显著的抗炎活性。Lyprinol是一种可重复、稳定的生物活性脂质来源,其效力比目前用作营养补充剂以改善炎症症状的植物/海洋油要强得多。
