Oral glucose (25 g) fed to seven healthy, conscious dogs resulted in an increase in peripheral plasma glucose from 109 +/- 3 to 178 +/- 10 mg/dl. Concurrently serum insulin increased in the portal vein to levels approximately threefold greater than those in the periphery. Hepatic insulin delivery rose from 10.8 +/- 0.7 to 59.0 +/- 19.9 m U/min at 60 min. coincident with an increased hepatic ins...

Haemodialysis patients display an increased cardiac mortality, which may be partly related to increased sympathoadrenal activity and insulin resistance. Fish oil decreases adrenal activation induced by mental stress and has an insulin sensitizing effect in healthy subjects. Whole-body glucose metabolism after oral glucose was studied in eight haemodialysis patients before and after a 3-week ora...

Ayurveda refers Mimusops elengi L. for the treatment of the diabetes. Considering the traditional claim of M. elengi in management of diabetes and the possible involvement of oxidative stress in pathogenesis of diabetes, the present study was aimed to evaluate the in vitro antioxidant and in vivo antihyperglycemic property of methanolic extract of bark of M. elengi (MEMeOH). In vitro antioxidan...

We previously showed that hypothalamic neuronal activity, as measured by the blood oxygen level-dependent (BOLD) functional MRI signal, declines in response to oral glucose intake. To further explore the mechanism driving changes in hypothalamic neuronal activity in response to an oral glucose load, we here compare hypothalamic BOLD signal changes subsequent to an oral vs. an intravenous (iv) g...

Introduction: Oral delivery is the most favorable route for insulin administration. The aim of this study was to generate new chitosan coated insulin nanoliposomes and then to assess the physiological efficacy of these nanoliposomes after oral administration in diabetic rabbits. Methods: Nanoliposomes with negative surface charge encapsulating insulin were prepared by reverse phase evaporat...

1. Blood pyruvate and lactate levels during oral and intravenous glucose tolerance tests are described in obese and non-obese non-diabetic, maturity-onset diabetic and insulin-requiring diabetic groups of women. 2. Mean fasting blood pyruvate levels were similar in non-diabetic, maturityonset diabetic and insulin-requiring diabetic subjects of similar degree of obesity. Mean levels were higher ...

Glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) are released during meals from endocrine cells located in the gut mucosa and stimulate insulin secretion from pancreatic beta-cells in a glucose-dependent manner. Although the gut epithelium senses luminal sugars, the mechanism of sugar sensing and its downstream events coupled to the release of the incretin ...

new-onset diabetes after transplantation (nodat) is one of the frequent complications following kidney transplantation. patients were randomized to receive cyclosporine a- or tacrolimus-based immunosuppression. fasting and oral glucose tolerance tests were performed, and the patients were assigned to one of the following three groups based on the results: normal, impaired fasting glucose/impair...
