摘　　要：圆小囊(SR)是兔回肠末端与盲肠相接处形成的一个壁厚而膨大的圆囊,主要由丰富的淋巴组织构成,为兔特有的外周免疫器官。圆小囊在兔的生理活动中具有重要地位,发挥着消化吸收、免疫防御、神经内分泌等多种生理功能。圆小囊结构特殊、功能复杂,在科学试验中具有重要研究价值和参考意义,在实际应用中具有广阔发展前景。论文从圆小囊的解剖学、组织学、影像学等方面总结了其结构特征,对圆小囊多种生理功能的研究进展做了综述,并对圆小囊抗菌肽的研究和应用进行了总结与展望。旨在为今后以圆小囊为研究对象的学者提供借鉴和参考,同时为宠物兔疾病临床诊断以及推动圆小囊抗菌肽的研究应用提供理论依据和支撑。The sacculus rotundus(SR)is a thick and enlarged sac formed at the junction of the terminal ileum and cecum in rabbits.It is mainly composed of rich lymphoid tissue and is a unique peripheral immune organ in rabbits.Sacculus rotundus plays an important role in the physiology of rabbits,which plays many physiological functions such as digestion and absorption,immune defense,and neuroendocrine.This paper summarizes the structural characteristics of sacculus rotundus from the aspects of anatomy,histology and imaging,reviews the research progress of various physiological functions of sacculus rotundus,and the research and application of sacculus rotundus antimicrobial peptides are summarized and prospected.The sacculus rotundus has a unique structure and complex functions,which have important research value and reference significance in scientific experiments.It also has broad development prospects in practical applications.This paper aims to provide reference and guidance for scholars who study the sacculus rotundus in the future,and to provide theoretical basis and support for the clinical diagnosis of pet rabbit diseases and the research and application of the sacculus rotundus antibacterial peptide.
