七彩山鸡胃肠组织学研究

通过常规石蜡切片，H-E染色，对三只120日龄七彩山鸡（phasianus colchicas）的胃肠道结构进行了组织学观察。结果表明：七彩山鸡胃肠管的黏膜层、肌层和管状消化腺发达，整个消化管黏膜固有层中都有淋巴组织存在。腺胃内有较多的单管状腺和复管状腺，肌胃肌层发达。小肠黏膜层最厚，绒毛致密且有分支，绒毛轴中心未见中央乳糜管，固有膜中单管肠腺丰富，黏膜下层缺如或很薄。大肠管壁具四层结构，有环状皱襞，皱襞上绒毛宽短稀疏，黏膜上皮中杯状细胞增多。将观察结果与其它鸟类进行了比较。

Study on gastro-intestinal histology of phasianus colchicas

Through common paraffin section and H-E stain,the study observes the histology of gastrointestinal frout of three four-motnth-old phasianus colchicas.The results are as follows: mucous layer,muscular layer and tubiform digestive gland are developed in stomach intestine tube of phasianus colchicas,and there exists lymphatic tissue in lamina propria of the all digestive tube;The glandular stomach has developed simple tubular gland and compound tubular gland,and muscular layer is developed in muscular stomach;mucous layer has developed of small intestine;villus is pykno and branch,and its core absent central lacteal and simple tubular gland are abundant in lamina propria;submucous layer is absent or more thinness;the tubal wall of the large intestine has four layers which include crico-plica;the villus of plica are broad and short and raritas,beaker cell enhance in epithelium mucosae.The observed result has been compared with other birds.
