Polysaccharide of Koidz (PAMK) is a biologically active component of , which has the effect of maintaining the immune homeostasis of the body. Therefore, this study constructed a model of PAMK to relieve LPS-induced gosling enteritis and observed the morphological changes of the small intestine after HE staining. ELISA was used to detect serum CRP, IL-1, IL-6, and TNF- levels; immunohistochemistry was used to detect the positive rate of IgA in the small intestine; TLR4, occludin, ZO-1, cytokines, and immunoglobulin mRNA expression in the small intestine were detected by qPCR; and intestinal flora of gosling excrement was analyzed by 16S rDNA sequencing to analyze the protective effect of PAMK on goslings enteritis and the impact on intestinal flora. The results showed that PAMK relieves LPS-induced gosling enteritis by maintaining the small intestine morphology, cytokine, tight junctions, and immunoglobulin relatively stable and improving the disorder of intestinal flora.
小柴胡多糖(PAMK)是[具体物质]的一种生物活性成分,具有维持机体免疫稳态的作用。因此,本研究构建了PAMK缓解LPS诱导的雏鹅肠炎模型,并观察了HE染色后小肠的形态变化。采用ELISA法检测血清CRP、IL-1、IL-6和TNF-水平;采用免疫组化法检测小肠中IgA的阳性率;通过qPCR检测小肠中TLR4、occludin、ZO-1、细胞因子和免疫球蛋白mRNA的表达;采用16S rDNA测序分析雏鹅粪便中的肠道菌群,以分析PAMK对雏鹅肠炎的保护作用及其对肠道菌群的影响。结果表明,PAMK通过维持小肠形态、细胞因子、紧密连接和免疫球蛋白相对稳定以及改善肠道菌群紊乱来缓解LPS诱导的雏鹅肠炎。
