Abstract
患有關節炎、心血管疾病會使用非類固醇抗發炎藥(nonsteroidal anti-inflammatory drugs, NSAIDs)治療,然而長期使用可能會導致胃潰瘍發生。先前研究指出,枸杞多醣體(Lycium barbarum polysaccharides, LBP)與藻藍素(C-phycocyanin, CPC)皆具有抗氧化、抗發炎等功能。然而尚未有研究探討給予胃潰瘍大鼠枸杞多醣體與藻藍素,是否能改善胃潰瘍與調節胃部微生物菌相。實驗將8週齡雄性Sprague-Dawley大鼠隨機分成五組(n=10-12):正常組、阿斯匹靈組、枸杞多醣體組(aspirin + 100 mg LBP/kg bw)、藻藍素組(aspirin + 50 mg CPC/kg bw)、枸杞多醣體+藻藍素組(aspirin + 50 mg LBP /kg bw + 25 mg CPC /kg bw)。於第一週至第九週給予LBP與CPC,第二週至第九週給予700 mg/kg bw阿斯匹靈誘發胃潰瘍。結果顯示,給予LBP能降低胃潰瘍分數與增加胃中雙岐桿菌屬,給予CPC能降低胃中脂質過氧化物及增加胃中雙岐桿菌屬;當合併給予LBP與CPC能降低胃中脂質過氧化物濃度、增加COX-1、NO、PGE2濃度及雙岐桿菌屬。對於阿斯匹靈誘發大鼠胃潰瘍,給予LBP能降低胃潰瘍指標,CPC可以改善氧化壓力,而合併給予LBP與CPC能增加胃部保護因子與改善氧化壓力,此外,補充LBP或CPC皆能增加雙岐桿菌屬,顯示無論LBP或CPC皆具有修復因阿斯匹靈誘發胃潰瘍的效果。
