Scanning Electron Microscope Observation on Intestinal Epithelial Mucosal of Thymallus arcticus yaluensis

In this paper,using the scanning electron microscopy to observe and study the intestinal mucosa of Thymallus arcticus yaluensis,the results show that the foregut folds along the direction of wavy bowel,the midgut was manifested as jagged,the folds of the hindgut is presented as the disorderly tumor-like;the microvilli of midgut and hindgut were significantly and showed obvious cluster-like;the numbers of goblet cells from the foregut to the hindgut increased significantly.
