【摘要】 观察了死于不同年令的9只大熊猫消化道的主要器官,包括口腔粘膜、舌、食管、胃、十二指肠、空肠、回肠和直肠的石蜡切片。大熊猫消化道的显微结构基本上与一般食肉类的相似,同时也呈现出对以竹子为主食的适应性特点,主要表现在单细胞和多细胞粘液腺丰富、小肠绒毛较长,肠道粘膜肌层与肌肉层较厚等。更多还原

【Abstract】 Specimens of the digestive tract of Giant panda, including the mucosa of oral cavity, esophagus, stomach, deudenum, jejunum, ilium, colon and rectum were taken from the carcases of 9 different aged animals and studied in paraffin section. These carcases were preserved in 10% formalin after death. The result observed in light microscopy shows that, in general, the microstuctures of different parts of panda digestive tract are similar to those of other carnivores. In addition to the similarity, some interesting specitic histotogical features are present, probably due to the adaptation to bamboo as its main food, such as, numerous unicellular and multicellular mucous glands, longer villi and thicker musculuris mucosae and tunica muscularis of the small intestine.更多还原
