鱼类肠道组织结构、功能、影响因素及其保护物质的研究进展

Research progress on the tissue structure, function, influencing factors and protective substances of fish intestine

摘要:

肠道可以吸收营养物质并抵御病原体、微生物和细菌毒素进入内部环境,因此在鱼类健康中起着重要作用。作为鱼类与外部环境接触面积最大的器官,肠道受到多种因素的侵害,严重制约了鱼类的健康生长。文章从鱼类肠道组织结构、肠道的屏障功能、引起肠道损伤的因素以及有效缓解肠道损伤的物质等四个方面进行综述,可为进一步了解鱼类肠道健康的分子机制及相关产品的研发提供参考。

Abstract:

Intestine plays an important role in fish health as it can absorb nutrients and defend against pathogens,microbes and bacterial toxins entering the internal environment.As the organ with the largest contact area between fish and the external environment,the intestine is invaded by many factors,which seriously restricts the healthy growth of fish.This article reviewed the intestinal tissue structure, intestinal barrier function,factors that cause intestinal damage and substances that could effectively alleviate intestinal damage in fish,in order to provide certain theoretical basis for protecting fish intestinal health and promoting the healthy development of aquaculture industry.
