摘要
采集0、1、2、3、4、5、6、10、14、18、22、26、30、34、38周龄健康中国黄羽鹌鹑的盲肠扁桃体,测量盲肠扁桃体的生长指标,观察盲肠扁桃体的显微组织结构及超微结构变化.结果表明:中国黄羽鹌鹑盲肠扁桃体位于回肠、盲肠、直肠三者连接处的盲肠基部,盲肠扁桃体近盲肠的基底部分由于盲肠壁增厚、增宽,容易与其他部位分离,盲肠扁桃体在鹌鹑孵化时已存在,0~38周龄皆具备完整的外部形态,表面光滑且饱满;盲肠扁桃体的结构由内到外分为黏膜、黏膜下层、肌层和浆膜,黏膜包括上皮、固有层和肠腺;在透射电镜下可见结构清楚的内质网、线粒体、溶酶体和肠绒毛,且线粒体嵴清晰可见;盲肠扁桃体质量、生长指数及左、右侧的长和宽的变化趋势基本保持一致,均为早期随着周龄的增加不断增长,后趋于平稳,绝对质量和生长指数均在6周龄达到最大,除22周龄右侧长径外,10~38周龄盲肠扁桃体生长指标间的差异均无统计学意义.中国黄羽鹌鹑盲肠扁桃体的发育在出生后逐渐发育,0~6周龄为快速发育期,在6周龄达到成熟,10~38周龄为成熟持续期.
The cecum tonsils of healthy Chinese yellow quail with ages of 0, 1, 2, 3, 4, 5, 6, 10, 14, 18, 22, 26, 30, 34 and 38 weeks were collected for the microstructure and the ultrastructural observation. The results showed that the cecum tonsil of Chinese yellow quail was located at the base of the cecum at the ileocecal-rectal junction, and the basal part of the cecum tonsil near the cecum was easily separated from other parts due to the thick and wide of the cecum wall. The cecum tonsil existed during the incubation of quails, and had a complete external shape at 0-38 weeks of age with smooth and full surface. The structure of the cecum tonsil was divided into mucosa, submucosa, muscular layer and serosa from the inside to the outside and the mucosa included epithelium, lamina propria and intestinal glands. The endoplasmic reticulum, mitochondria, lysosomes and intestinal villi with clear structure were observed under transmission electron microscopy, and mitochondrial cristae was clearly visible. The absolute weight, length and width of cecum tonsils gradually increased with age, reaching the maximum at 6-week age, and kept unchanged at 10-38 weeks of age. It showed that the development of cecum tonsil of Chinese yellow quail gradually developed after their birth. The cecum tonsil developed rapid at 0-6 week of age, matured at 6-week age, and kept matured to 38-week age.
