An account is given of asymptomatic diabetes mellitus. To determine the incidence in 200 patients with senile cataract 3 tests are described, namely, a modified standard glucose tolerance test, a provocative steroid glucose tolerance test, and a standard glucose tolerance test. Known diabetics and patients with a fasting blood glucose in excess of 5.5 mmol/l or glycosuria were excluded. Eighty-...

BACKGROUND In cystic fibrosis, highly variable glucose tolerance is suspected. However, no study provided within-patient coefficients of variation. The main objective of this short report was to evaluate within-patient variability of oral glucose tolerance. METHODS In total, 4,643 standardized oral glucose tolerance tests of 1,128 cystic fibrosis patients (median age at first test: 15.5 [11.5...

A series of 45 patients who had a myocardial infarction before the age of 45 years has been studied and investigated for alterations of glucose tolerance, as shown by standard and prednisolone-primed glucose tolerance tests. Abnormal responses to standard glucose tolerance tests and prednisolone-primed glucose tolerance tests were obtained in 75.5 per cent of patients with myocardial infarction...

Introduction: Repeated hyperglycemia play an important role in the development of atherosclerosis in diabetic patients. Endothelium is the organ of the first-line defense against atherosclerosis and nitric oxide has a major role in this task. The aim of this study was to determine changes in plasma nitric oxide metabolites concentration during glucose tolerance test in type 2 diabetic rats. Me...

radioactive iodine therapy is commonly used as an adjuvant therapy in follicular and papillary thyroid carcinoma and also in the treatment of graves’ disease. the basis of which is the accumulation of radioactive iodine by the sodium-iodide symporter (nis) in the thyroid gland. expression of nis by extrathyroidal tissues including islets of pancreas has been reported. radioactive iodine uptake ...

BACKGROUND AND PURPOSE The purpose was to assess the prevalence of disorders of glucose metabolism and insulin resistance in Japanese ischemic stroke patients with no history of diabetes by performing 75-gram oral glucose tolerance test (OGTT). METHODS We recruited 427 ischemic stroke patients (atherothrombotic infarction, n=220; lacunar infarction, n=125; cardioembolic infarction, n=82). OGT...

dopaminergic signaling is one of the regulatory pathways being investigated for its implication in glucose metabolism. the aim of this study was to determine the effect of cabergoline on biochemical and anthropometric parameters in prediabetes stage (impaired fasting glucose and impaired glucose tolerance). in this double blind, placebo-controlled, pilot study, 27 prediabetic adults were random...

BACKGROUND The Canadian and American Diabetes Associations recommend the use of an oral glucose tolerance test to screen for abnormal glucose tolerance among women with polycystic ovary syndrome when their fasting plasma glucose level is 5.7 mmol/L or more (Canadian guideline) and 5.6 mmol/L or more (American). Our objective was to determine the predictive value of 5.6 mmol/L as a fasting plasm...
