摘　　要：肠胃炎、便秘和腹泻等常见的消化道疾病一直是困扰竹鼠养殖和野生保护的一大难题。通过组织学方法对中华竹鼠空肠和回肠组织结构进行研究,为其物种的延续保存和科学养殖提供理论依据。采用常规解剖技术、石蜡组织制片技术(H-E染色),以及使用光学显微镜对中华竹鼠的空肠和回肠组织结构进行观察、显微摄影和测量分析。结果表明:中华竹鼠空肠与回肠的黏膜上皮层均为单层柱状上皮,含有许多柱状上皮细胞和杯状细胞,回肠相比于空肠,其绒毛增高,肠腺数量相对减少,隐窝深度相对增大,黏膜肌层更发达,肌纤维间隙少。空肠的黏膜层含有两层颜色深浅不同的隐窝,回肠黏膜肌层和肌层外都有一层脂肪细胞。Common digestive tract diseases such as gastroenteritis,constipation,diarrhea and so on,have been a big problem in the breeding process and protection of wild Rhizomys sinensis.The object of the research was to investigate the histological structure of jejunum and ileum of Rhizomys sinensis by histological method to provide theoretical basis for the continuation of the species and scientific breeding.The jejunum and ileum histological structure of Rhizomys sinensis were observed under light microscope by using conventional anatomical techniques,paraffin tissue preparation and H-E staining techniques.The results showed that the mucosa epithelium of jejunum and ileum of Rhizomys sinensis was simple columnar epithelium,containing many columnar epithelial cells and goblet cells.The ileum had higher villi,fewer the intestinal glands,greater crypt depth,more developed muscularis mucosae,and less fiber gap than those of the jejunum.Moreover,the mucosa of jejunum contained two layers different color of crypt,and the ileum had a layer of fat cells both outside of the muscularis mucosae and muscular layer.
