Abstract:
Objective To investigate the adaptive expression of brush-border disaccharidases in the residual digestive tract of rats following a total small bowel resection. Methods Mucosa was scraped off with a piece of glass from the colon,the cecum and the duodenum of the rats with a total small bowel resection (experimental group,n =10) and normal rats (control group,n =10). Diaccharidase activities were determined in accordance with the method of Dahlqvist. Results Specific activities and total activities of sucrase,maltase in the colon,the cecum and the duodenum in the experimental group were significantly greater than those in the control group( P 0.05). Conclusions Total small bowel resection caused significant adaptive expression of brush-border sucrase and maltase in the residual digestive tract in the rats after a total small bowel resection.
