Hyperglycemia is an important independent risk factor in the development of coronary artery disease. Sixty one patients suffering from chronic and acute myocardial infarction out of which 12 patients were diabetic and 10 normal control subjects were investigated. The patients without diabetes and control subjects were subjected to oral and intravenous glucose tolerance tests. It was observed th...

Oral galactose tolerance tests were performed on 56 patients with liver disease, 31 with diabetes mellitus and 17 normal subjects. Intravenous galactose tolerance tests were done on 25 liver disease, 6 diabetes mellitus and 6 normal subjects. Each liver disease was histologically comfirmed by needle biopsy under laparoscopy. Serum galactose and glucose were measured gaschromatographically. Oral...

Background. Islet transplantation can restore normoglycemia to patients with unstable type 1 diabetes mellitus, but long-term insulin independence is usually not sustained. Identification of predictor(s) of islet allograft dysfunction (IGD) might allow for early intervention(s) to preserve functional islet mass. Methods. Fourteen islet transplantation recipients with long-term history of type 1...

Minimal model analysis of intravenous glucose tolerance test (IVGTT) glucose and insulin concentrations offers a validated approach to measuring insulin sensitivity, but model identification is not always successful. Improvements may be achieved by using alternative settings in the modeling process, although results may differ according to setting, and care must be exercised in combining result...

The simultaneous assessment of quantitative indexes of insulin secretion and action in a single individual is important when quantifying their relative role in the evolution of glucose tolerance in different physiopathological states. Available methods quantify these indexes in relatively nonphysiological conditions, e.g., during glucose clamps or intravenous glucose tolerance tests. Here, we p...

Type 2 diabetes mellitus (T2DM) has become prevalent pandemic disease in view of the modern life style. Both diabetic population and health expenses grow rapidly according to American Diabetes Association. Detecting the potential onset of T2DM is an essential focal point in the research of diabetes mellitus. The intravenous glucose tolerance test (IVGTT) is an effective protocol to determine th...

To study the carbohydrate metabolism in uremic patients, the intravenous glucose tolerance test (iv GTT) and insulin sensitivity test were investigated on 69 patients with chronic renal failure, 27 of whom were under the dialysis treatment. 1) Abnormal K-values averaging 1.05 were obtained in uremic patients (creatinine clearance less than 20 ml/min). 2) Carbohydrate intolerance in uremic patie...
