银耳多糖、银耳孢子多糖及黑木耳多糖以每天70mg/kg灌胃2d,均明显抑制大鼠应激型溃疡的形成;以每天165mg/kg灌胃124,能促进醋酸型胃溃疡的愈合。对胃酸分泌和胃蛋白酶活性无明显影响。本研究表明,这三种多糖均有抗溃疡作用。
Tremella Polysaccharides, Tremella Spore Polysaccharides and Auricularia auricula polysaccharides were intragastrically administered at 70 mg/kg every day for 2 days. All of them significantly inhibited the formation of stress ulcers in rats; gavage with 165 mg/kg/day 124 could promote the healing of acetic acid-type gastric ulcers. No significant effect on gastric acid secretion and pepsin activity. This study shows that all three polysaccharides have anti-ulcer effects.
