中央乳糜管

结果：LPS组淋巴管管径变大，运动频率减少，镜下见小肠绒毛中央乳糜管及粘膜下淋巴管丛极度扩张；

RESULTS : In LPS group , the mesenteric lymphatic diameter was greater than that in the control and contractile frequency was decreased , the villi central lacteal and submucosal microlymphatics of small intestine was extremely dilated under microscope .

脂肪进入中央乳糜管是通过空泡转运或内皮细胞连接处。

The path by which fat get into lacteals may be transmited by the vesicles of endothelium , or by the interendothelial junctions .

空肠和回肠的肠绒毛变得短而粗，肌层的厚度增大，未见中央乳糜管。

The villi of jejunum and ileum became shorter and thicker , the thickness of muscular layer became accrescent , no central chyliferous vessel .

小肠绒毛上皮是单层柱状上皮，粘膜肌不明显，有中央乳糜管，无十二指肠腺。

Epithelium of intestinal villus is simple columnar epithelium , muscularis mucosa is not obvious , and there are central lacteals in lamina propria but there are not duodenal glands .

结论：淋巴管铸型清晰地显示家兔回肠壁黏膜层丰富的中央乳糜管和毛细淋巴管丛以及黏膜下层、肌层毛细淋巴管和大量的淋巴管的三维结构。

Numerous impressions of the endothelial nuclei , rich central lacteals and lymphatic capillary plexus in the ileum mucosa , lymphatic capillary and lymphatics in the submucosa and muscular layer are observed on the lymphatic corrosion cast .
