Intestinal D-fructose absorption in 31 children was investigated using measurements of breath hydrogen. Twenty five children had no abdominal symptoms and six had functional bowel disorders. After ingestion of fructose (2 g/kg bodyweight), 22 children (71%) showed a breath hydrogen increase of more than 10 ppm over basal values, indicating incomplete absorption: the increase averaged 53 ppm, ra...
Monospecific antisera were produced to two chylomicron apoproteins (apoB, apoA-I) and utilized for indirect immunofluorescent localization of these apoproteins within rat intestinal epithelium during normal and impaired lipid absorption. Isolated intestinal epithelial cells prepared after different periods of lipid absorption from in situ intestinal segments revealed a rapid increase in fluores...
Curcumin is the yellow pigment of turmeric. In addition to its positive safety profile, curcumin is reported to have beneficial pharmacologic effects as an antioxidant, antitumor, and anti-inflammatory agent, along with other promising pharmacologic effects on the cardiovascular and digestive systems. Curcumin is poorly absorbed, which limits its value in clinical application. In order to impro...
The long controversy over whether triglycerides are hydrolyzed preliminary to their absorption from the intestine may be ascribed to the difficulties in designing an experiment without alternative interpretations. In the present study it was hoped that an unequivocal experiment could be designed by labeling both the glycerol and the fatty acid moieties of ingested fat and examining the glycerid...
OBJECTIVES To test the hypothesis that a controlled-release preparation of cysteamine, with fewer daily administrations, would improve the quality of life for patients with cystinosis. STUDY DESIGN A specifically designed nasoenteric tube was used to administer cysteamine directly into the stomach, small intestine (SI) and colon and serial plasma cysteamine, serum gastrin and leukocyte cystin...
The purpose of this review is to update the reader on our current knowledge of the digestion, uptake, and transport of dietary lipid. In particular, it discusses how intestinal lipid transporters may play a role in the uptake of lipids by the enterocytes, and how chylomicrons are formed in the enterocytes and packaged for export into the lymphatic system through exocytosis. The classification a...
Three tests of small intestinal function were performed at 3100 m and 4846 m to seek evidence of malabsorption of high altitude. Xylose tolerance did not change in 11 subjects but, in three who ascended to 5600 m, one-hour xylose levels were significantly lower. The results of an oxalate loading test did not suggest significant fat malabsorption. A direct fat absorption test using chylomicron l...
Previously, we demonstrated that exercise can cause small intestinal injury, leading to loss of gut barrier function. The functional consequences of such exercise-induced intestinal injury on subsequent food digestion and absorption are unclear. The present study determined the impact of resistance-type exercise on small intestinal integrity and in vivo dietary protein digestion and absorption ...
pound responsible for the pungent character of various hot peppers (Capsicum), and it is famous for its pungent taste, burning sensation, and various effects on body temperature and gastric acid secretion. These features of capsaicin are considered to be generated by capsaicin associating with the capsaicin receptor, or the transient receptor potential cation channel of vanilloid type 1 (TRPV1)...
In contrast to the extensively reported therapeutic activities, far less attention has been paid to the intestinal absorption of the total saponins from Radix Ilicis Pubescentis (in Chinese Mao-Dong-Qing, MDQ). This study aimed to investigate the intestinal absorption characteristics of ilexgenin A (C1), ilexsaponin A1 (C2), ilexsaponin B1 (C3), ilexsaponin B2 (C4), ilexsaponin B3 (DC1), and il...
