In human, digestion of cooked starch mainly involves breaking down of α-amylase to α-limit dextrins and small linear malto-oligosaccharides, which are in turn hydrolyzed to glucose by the gut mucosal maltase-glucoamylase (MGAM). Human pancreatic α-amylase (HPA), amino- and carboxyl-terminal portions
The aim of this study was to evaluate the effect of alga Ulva lactuca polysaccharides (ULPS) on key enzymes related to diabetes and obesity. This marine natural product, ULPS, exerted potential inhibition on key enzymes related to starch digestion and absorption in both plasma and small intestine
AO-128 is a potent and structurally novel inhibitor of the intestinal disaccharidases, such as maltase and sucrase. Genetically obese-diabetic mice, KKA(y), were used to examine the acute or long-term effectiveness of this compound. AO-128 decreased a postprandial rise in blood glucose after sucrose
OBJECTIVE
To investigate the role of octreotide, a somatostatin (SST) analog with anti-inflammatory effects, on the digestive and absorptive functions of jejunum in rats fed a high-fat diet, as well as its therapeutic prospects for diet-induced obesity.
METHODS
Rats were divided into three groups
The excessive consumption of starch in human diets is associated with highly prevalent chronic metabolic diseases such as type 2 diabetes and obesity. α-Glucosidase enzymes contribute to the digestion of starch into glucose and are thus attractive therapeutic targets for diabetes. Given that the
It is well known that adrenalectomy (ADX) reverses the eating and energy balance disturbances in a variety of models of obesity associated with elevated food intake. We have previously demonstrated enhanced functional activity in the small intestine of neonatally monosodium glutamate-treated (MSG)
Edible plants constitute a potential source for controlling postprandial hyperglycemia and oxidative stress. The objective of this study was to investigate in vitro antioxidant and intestinal α-glucosidase inhibitory activities of Mesona chinensis (MC). In addition, the acute effect of MC on
OBJECTIVE
To investigate whether high-fat diet induced obesity was associated with variation of glucose absorption in small intestinal mucosa of rats.
METHODS
46 male SD rats were randomly divided into high-fat diet group (n = 31) and control group (n = 15), fed with high-fat diet and normal diet
Morphologic and functional adaptations of the functioning intestine were evaluated in 41 patients before and after biliopancreatic bypass for morbid obesity. This surgical procedure diverts pancreatobiliary secretions via the duodenum and the jejunum into the colon, the remaining small intestine
OBJECTIVE
To investigate the effects of the somatostatin analogue, octreotide, on maltose and sucrase activities and expression of glucose transporter type 2 (GLUT2) in obese rat intestinal mucosa.
METHODS
We divided 49 Sprague-Dawley rats into a group of 31 high fat diet-induced obese rats and a
The obese spontaneous hypertensive rat/NIH-corpulent (SHR/N-cp) rat exhibits some of the metabolic and pathologic alterations associated with non-insulin-dependent diabetes mellitus and hypertension. The current study was conducted to investigate the influence of phenotype (ob versus In) and source
The activities of intestinal disaccharidases are known to be responsive to changes in the dietary intake of carbohydrates in the adult rat. Little is known, however, regarding the activities of these enzymes in obese subjects and how they are affected by differing carbohydrate intakes. To evaluate
Inhibition of intestinal α-glucosidases and pancreatic α-amylases is an approach to controlling blood glucose and serum insulin levels in individuals with Type II diabetes. The two human intestinal glucosidases are maltase-glucoamylase and sucrase-isomaltase. Each incorporates two family 31
Antiobesity and antidiabetic actions of the alpha-glucosidase inhibitor AO-128 were examined using genetically obese-diabetic rats, Wistar fatty. Ten-week-old, male fatty rats were kept on CE-2 diet containing 10 or 25 ppm of AO-128 for 4 weeks. The average drug intake was calculated to be 0.74 or
Small intestinal morphologic and biochemical changes were studied following jejuno-ileal bypass for obesity after body weight stabilization had occurred. Four patients underwent biopsy of in-continuity and bypassed jejunal and ileal segments of the small intestine 11 to 22 months after the bypass
