Effect of Variation of Dietary Intake of Starch and Sucrose on the Activity of Sucrase and Lactase in Jejunum of Adult Rats
نویسندگان
چکیده
The problem of the regulation of activity of intestinal disaccharidases, especially lactase, has attracted the attention of researchers for many years (6,8); there are still many unresolved questions. This chapter, which deals with the authors' recent experiments with rats, summarizes data concerning (a) the effect of variation of carbohydrate intake on the activity of sucrase and lactase, (b) the mechanisms involved in changes of the activity of disaccharidases as influenced by the variation of carbohydrate intake, and (c) the locus of the first expression of the effect of the variation of carbohydrate intake along the height of the crypt-villus columns.

Dietary regulation of intestinal glucohydrolases in adult rats: comparison of the effect of solid and liquid diets containing glucose polymers, starch, or sucrose.
For 1 wk, 3-mo-old male rats were fed a low-starch (5 cal%), high-fat (73 cal%, corn oil) diet followed by a high-glucose-polymer (70 cal%), low-fat (7 cal%, corn oil) or a middle-glucose-polymer (40 cal%), middle-fat (37 cal%, corn oil) diet. Other animals were fed similar diets but with starch or sucrose instead of the glucose polymers. Rats were sacrificed 2 or 7 days later. Food intake, bod...
متن کاملDietary-induced increases of disaccharidase activities in rat jejunum.
A study was carried out to examine whether the responsiveness of small intestinal epithelial cells to dietary carbohydrate varied during the daily 24 h cycle. The effect of sucrose on disaccharidase activities was compared during a period of decreasing disaccharidase activities, i.e. between 22.00 and 10.00 hours, and increasing disaccharidase activities, i.e. between 10.00 and 22.00 hours, in ...
متن کاملDietary carbohydrates enhance lactase/phlorizin hydrolase gene expression at a transcription level in rat jejunum.
We have previously shown that dietary sucrose stimulates the lactase/phlorizin hydrolase (LPH) mRNA accumulation along with a rise in lactase activity in rat jejunum [Goda, Yasutake, Suzuki, Takase and Koldovský (1995) Am. J. Physiol. 268, G1066-G1073]. To elucidate the mechanisms whereby dietary carbohydrates enhance the LPH mRNA expression, 7-week-old rats that had been fed a low-carbohydrate...
متن کاملEffect of diet upon intestinal disaccharidases and disaccharide absorption.
The administration of a carbohydrate-containing diet for 24 hours to rats previously fasted for 3 days led to a twofold increase in total intestinal sucrase and sucrase specific activity. The specific activity of maltase was similarly increased, but lactase activity was unaffected. The sucrose-containing diet led to a greater increase in sucrase than maltase activity, whereas the converse was t...
