Jejunal disaccharidases in protein energy malnutrition and recovery.
The jejunal disaccharidases, sucrase, maltase and lactase, were determined in jejunal biopsies obtained from 43 malnourished children and 10 controls. In the study group, 63% were girls and 93% had severe malnutrition. Lactase activity was significantly reduced in third and fourth degree malnutrition (p < 0.05 and p < 0.005, respectively), but maltase activity was significantly reduced only in ...
متن کاملActivity of duodenal disaccharidases in relation to normal and abnormal mucosal morphology.
Endoscopic duodenal biopsy specimens from 100 predominantly adult Caucasian patients under investigation for gastrointestinal symptoms were used to establish reference ranges for lactase, sucrase, and maltase in the duodenum. Duodenal and jejunal disaccharidase values were compared and the association between disaccharidase activity and morphology in the duodenum was examined. Mean lactase acti...
متن کاملPrevalence of lactase deficiency in British adults.
The prevalence of lactase deficiency in British adults is unknown. Examination of the distribution of lactase activities in single and multiple biopsies of jejunum indicated that 0.8 U/g wet weight was a suitable cut-off point to separate lactase deficient patients from others. One hundred and fifty white British adults were selected, none of whom had significant intestinal disease and all of w...
متن کاملAbsorption of lactose and its digestion products i the normal and malnourished Ugandan.
Primary or specific lactase deficiency is very common in healthy members of the Baganda and other Bantu tribes of Uganda after the first three or four years of life (Cook and Kajubi, 1966; Cook, 1967). Secondary lactase deficiency has been recorded in some cases of kwashiorkor (Bowie, Brinkman, and Hansen, 1965; Stanfield, Hutt, and Tunnicliffe, 1965), where there is mucosal damage in the proxi...
متن کاملDisaccharidase levels in the small intestine in patients with diarrhoea following vagotomy and pyloroplasty.
Diarrhoea is a common sequel to vagotomy and pyloroplasty but its cause is unknown. One of our patients who developed this complication had an abnormal lactose barium meal and responded well to a lactose-free diet. This led us to make a systematic study of disaccharidase activity in the small intestine in patients with diarrhoea following vagotomy and pyloroplasty. The small-intestinal disaccha...
