Breakfasts of lentils or wholemeal bread of identical carbohydrate content were taken by seven healthy volunteers. The lentils produced a significant 71% (p less than 0.001) reduction in the blood glucose area and flattened the plasma insulin and gastric inhibitory polypeptide responses by comparison with the bread. In addition, the lentil breakfast was(More)
Bombesin, a peptide with widespread biological actions, has been demonstrated in human tissues by immunological methods. To investigate its effect in man, synthetic bombesin was infused at low doses in six male volunteers. Bombesin at 2.4 pmol kg-1 min-1 produced significant rises in plasma insulin, glucagon, pancreatic polypeptide, gastrin,(More)
The treatment of obesity by intestinal bypass provides a unique model for the investigation of gut hormone release from the functionally deranged bowel. We have examined the postprandial response of eight circulating gut or pancreatic peptide hormones in 16 preoperative obese patients, 20 patients with jejunoileal bypass, 38 patients with biliopancreatic(More)
A mother and her son who have lipoprotein phenotype I are described. They differed from subjects with lipoprotein lipase deficiency in that lipoprotein lipase was present in adipose tissue respectively at 30- and 2-fold the levels seen in normal subjects, and from subjects with apoprotein C-II deficiency in that apoprotein C-II was present in their plasma.(More)
We have investigated the effect of cystic fibrosis on alimentary hormones in 10 children by measuring the pancreatic and gut hormone rsponse to a milk drink. Plasma insulin and gastric inhibitory peptide were both significantly reduced (P < 0.05 and P < 0.005, respectively, at 15 min) in the patients with cystic fibrosis, compared with controls, even though(More)
Differences in pancreatic and gut-hormone release between breast-fed and bottle-fed infants have not been documented although these hormones may play a key role in postnatal adaptation. In a study of 77 six-day-old healthy term infants, bottle-fed neonates ('Cow and Gate Premium') had significant changes in plasma-concentrations of insulin, motilin,(More)
The effect of colonic infusion of various solutions on submaximal pentagastrin-stimulated gastric secretion was determined in healthy volunteers. Hypertonic (823 mOsm/kg) glucose, mannitol, and saline, and also isotonic glucose significantly induced a marked and sustained inhibition of gastric acid secretion of 74%, 66%, 79%, and 54%, respectively. A(More)
Fifty-gram carbohydrate tolerance tests were performed on healthy volunteers to test the activity and specificity of an alpha-glucoside hydrolase inhibitor, acarbose (BAY g 5421). Two hundred milligrams acarbose reduced the area under the blood glucose response curve by 89% (P less than 0.001) after sucrose by 80% (P less than 0.002) after starch, by 19%(More)
The fasting and postprandial levels of insulin, gastric inhibitory polypeptide, gastrin, motilin, human pancreatic polypeptide, enteroglucagon and neurotensin have been measured in 10 subjects with a permanent ileostomy and in 10 healthy control subjects matched for age and sex. Most of the levels were similar in the two groups but the group that had(More)
1. The pathophysiology of the dumping syndrome is poorly understood. Plasma levels of four small intestinal hormones have been measured after an oral glucose provocation test in 19 patients with dumping symptoms and in matched controls. 2. Plasma levels of neurotensin, a newly discovered highly potent, hypotensive ileal peptide, were significantly increased(More)
