Effect of diet upon intestinal disaccharidases and disaccharide absorption.
A lack of disaccharidases can result in the inhibition of complete decomposition of carbohydrates, as well as in the absorption of monosaccharides conversion and utilization (Karamouz et al.
The pathophysiology involved is the loss of disaccharidases in these areas and the resulting carbohydrate malabsorption which provides excess substrate for microbial growth.
Also, Et0Ac and n-BuOH fractions inhibited in vitro disaccharidases activities after an acute treatment.
The mechanism of glucose reduction is likely to be multifactorial, and we suggest the factors related with the decreased activity of mucosal disaccharidases important for further investigation.
Validation results showed the correlation coefficients of the disaccharidases to be 0.

Laboratory tests: The definitive test for diagnosis of CSID is the measurement of intestinal disaccharidases following small bowel biopsy.
Additionally, COR has a significant stimulating influence on intestinal disaccharidases and alkaline phosphatases, and also significantly improve terminal digestive enzyme activities (Platel and Srinivasan, 2001a).
The fact that HFCS consists mainly of two monosaccharides, while suc-rose is a disacchande, may also not be insignificant, in order to be absorbed as its constituent monosaccharides, sucrose must first be hydrolyzed by intestinal mucosal disaccharidases.
