AbstractBackground:(commonly known as Bael, golden apple) was formerly described to have anti-hyperglycemic activity. The present study aimed to explore the possible effects, in depth, ofMethods:This research begins with fasting blood glucose and oral glucose tolerance test (OGTT) to evaluate the primary anti-hyperglycemic effect in chemically induced type 2 diabetic rats. Furthermore, the plasma insulin concentration and serum glucose level were studied, which include measuring the sucrose content in six different segments of the gastrointestinal (GI) tract of the rats following oral sucrose feeding. An in situ, perfused, intestinal model in rats and glucose-fiber binding assay were conducted to find the effects ofResults:Treatment of extracts suppressed blood glucose elevation after oral sucrose (2.5 g/kg) administration and significantly (p<0.05) improved oral glucose tolerance in type 2 diabetic rats.Conclusions:The findings demonstrate that anti-hyperglycemic activity of

Vertical sleeve gastrectomy (VSG) has gained interest as a low morbidity bariatric surgery, which is effective in producing weight loss and causing type 2 diabetes resolution. However, the efficacy of VSG to prevent the onset of type 2 diabetes has not been previously investigated. VSG or sham surgery was performed on 2-month-old prediabetic male University of California Davis-type 2 diabetes mellitus rats. Sham-operated animals were either sham-operated ad libitum fed (S-AL) or were weight-matched to VSG-operated animals (S-WM). Diabetes onset was determined by weekly nonfasting blood glucose measurements. Animals underwent oral glucose tolerance tests at 1 and 4 months after surgery and indirect calorimetry at 1.5 months after surgery. VSG surgery significantly delayed diabetes onset compared with both S-AL and S-WM animals. VSG-operated animals ate 23% less and weighed 20% less than S-AL. Energy expenditure did not differ between VSG-operated animals and controls. Results from the oral glucose tolerance tests demonstrate improved glucose tolerance and islet function in VSG-operated animals compared with S-AL and S-WM. Nutrient-stimulated glucagon-like peptide (GLP)-1, GLP-2, and peptide YY excursions were greater in VSG-operated animals. VSG surgery resulted in decreased fasting plasma insulin, ghrelin and lipid concentrations, and markedly higher fasting plasma adiponectin and bile acid concentrations, independent of body weight. Increases of circulating bile acid concentrations were due to selective increases of taurine-conjugated bile acids. Thus, VSG delays type 2 diabetes onset in the University of California Davis-type 2 diabetes mellitus rat, independent of body weight. This is potentially mediated by increases of circulating bile acids, adiponectin, and nutrient-stimulated GLP-1 secretion and decreased circulating ghrelin concentrations.

Abstract Context: In persons with impaired glucose tolerance (IGT), both impaired insulin secretion and insulin resistance contribute to the conversion to type 2 diabetes mellitus (T2DM). However, few studies have used criterion standard measures to asses the predictive value of impaired insulin secretion and insulin resistance for the conversion to T2DM in a Caucasian IGT population. Objectives: The objective of the study was to determine the predictive value of measures of insulin secretion and insulin resistance derived from a hyperglycemic clamp, including the disposition index, for the development of T2DM in a Caucasian IGT population. Design, Setting, and Participants: The population-based Hoorn IGT study consisted of 101 Dutch IGT subjects (aged &lt; 75 yr), with mean 2-h plasma glucose values, of two separate oral glucose tolerance tests, between 8.6 and 11.1 mmol/liter. A hyperglycemic clamp at baseline was performed to assess first-phase and second-phase insulin secretion and insulin sensitivity. During follow-up, conversion to T2DM was assessed by means of 6-monthly fasting glucose levels and yearly oral glucose tolerance tests. Results: The cumulative incidence of T2DM was 34.7%. Hazard ratio for T2DM development adjusted for age, sex, and body mass index was 5.74 [95% confidence interval (CI) 2.60–12.67] for absence of first insulin peak, 1.58 (95% CI 0.60–4.17) for lowest vs. highest tertile of insulin sensitivity, and 1.78 (95% CI 0.65–4.88) for lowest vs. highest tertile of the disposition index. Conclusions: In these Caucasian persons with IGT, the absence of the first insulin peak was the strongest predictor of T2DM.
