摘要:

旨在研究猴头菇多糖对感染番鸭呼肠孤病毒(MDRV)雏鸭肠道黏膜免疫和抗氧化能力的影响。通过建立模拟MDRV自然感染发病模型,将200只1日龄健康雏番鸭随机分为空白对照组、猴头菇多糖对照组、同居感染对照组和猴头菇多糖预防组。各试验组番鸭在同居感染后第1、3、6、10、15、21天,采集样品测定各指标。结果显示,猴头菇多糖能够不同程度促进感染呼肠孤病毒雏番鸭肠道SIgA、IFN-γ、IL-4的分泌,具有维持肠道黏膜免疫平衡的作用;且显著(P<0.05)提高SOD活性和GSH含量,降低了MDA含量,具有提高机体抗氧化酶活性、清除体内自由基、抑制脂质过氧化的作用。结果表明,猴头菇多糖对雏番鸭肠道黏膜免疫具有较显著的调节作用,且能提高机体抗氧化能力,有效减轻呼肠孤病毒对其肠道屏障功能的损伤。

Abstract:

The aim of this study was to reveal the effect of Hericium erinaceus polysaccharide(HEP) on the intestinal mucosal immune and antioxidant capacity of ducklings which were infected with muscovy duck reovirus(MDRV).Through the establishment of simulation model which was similar with MDRV natural infection,200 of 1-day-old healthy ducklings were randomly divided into blank control group,HEP control group,cohabitation infected control group and HEP prevention group.The samples from ducklings in each experimental group were collected and determined in the first day,the third day,the sixth day,the tenth day,the fifteenth day and the twenty-first day after cohabitation infection.The results showed that,HEP could promote the secretion of SIgA,IFN-γ and IL-4 on intestinal of infected MDRV ducklings in different degree,also with the maintenance of intestinal mucosal immune balanced effect,and increased SOD activity and GSH content,decreased the content of MDA significantly,it turned out to have the function of improving antioxidase activity,removing free radicals and inhibiting lipid peroxidation.These results indicated that HEP had certain effect on regulating intestinal mucosal immunity of the ducklings and also improving the ability of anti-oxidation,reducing the intestinal barrier function which was damaged by MDRV effectively.
