We assessed the analytical performance of the co-immobilized hexokinase (EC 2.7.1.1) and glucose-6-phosphate dehydrogenase (EC 1.1.1.49) method for D-glucose analysis on the Technicon SMAC. The enzyme-containing coils were usable for one month, or 12 000 tests. Bilirubin, hemoglobin, lipemia, creatinine, uric acid, citric acid, and ascorbic acid did not interfere. Results with this method were compared to those by the National Glucose Reference Method. The upper limits of the total error estimate (a combination of random and systematic errors) were 76, 74, and 125 mg/liter at concentrations of 500, 1200, and 3000 mg/liter, respectively. The error estimates were less than allowable errors based on medical usefulness; thus the method was judged to perform acceptably with respect to the Reference Method. We also present performance data for the routine SMAC glucose oxidase (EC 1.1.3.4)/Peroxidase (EC 1.11.1.7) 3-methyl-2-benzothianolinone hydrazone-N,N-dimethylaniline method, the direct hexokinase method with the Du Pont aca, and the glucose oxidase oxygen-rate method with the Beckman Glucose Analyzer.

Studies are reported on the reaction kinetics of the glucose assay according to Trinder which involves the specific oxidation of glucose by glucose oxidase and the determination of the hydrogen peroxide released by means of phenol and 4-aminophenazone in the presence of peroxidase. The results have been used to develop a general kinetic fixed-time method for the analysis of glucose in whole blood and serum. The single reagent method has been adapted to the ENI GEMSAEC centrifugal analyzer and to the Abbott ABA-100 analyzer. The procedures exhibited excellent precision and the results correlated well with those obtained by the hexokinase method, Linearity was achieved from 3 to 64 mmol/1 glucose for the GEMSAEC method, and from 3 to 33 mmol/1 glucose for the ABA-100 method. Reagent or sample blank corrections were not necessary. There were no interferences from various drugs, hemoglobin, bilirubin, or lipemia.

A technique for pancreatectomy was described for the American eel. In this fish, the operation was not followed by the typical signs of diabetes mellitus. Histodensitometric determination of liver glycogen showed no major differences between operated controls and pancreatectomized eels. The absence of a specific hyperglycemia, previously reported with the hexokinase method, was confirmed with the glucose oxidase technique; however, the more specific hexokinase method gave consistently lower values. Breakdown of adipose tissue and hyperlipemia were absent.

Insulin resistance is an important risk factor of cardiovascular disease. This study was performed to determine the effects of valsartan on insulin sensitivity in patients with primary hypertension. In this study, non-obese subjects with primary hypertension and a reference group of healthy subjects matched by age, sex and body mass index were evaluated; patients with any other causes of peripheral insulin resistance and hyperlipidaemia were excluded. The effect of valsartan on insulin resistance, assessed by homeostasis model assessment (HOMA-IR), fasting serum insulin levels, determined by radioimmunoassay, and fasting blood glucose concentrations, measured by the glucose oxidase method, were evaluated. All obtained data were evaluated by Pearson correlation analysis. Before valsartan treatment, the fasting serum insulin levels were significantly elevated in the 20 hypertensive patients with primary hypertension compared with the 20 subjects in the reference group (19.6 +/- 7.1 versus 8.7 +/- 1.9 microIU/ml). The fasting serum insulin levels correlated with HOMA-IR. Correlation analysis also showed a significant relationship between HOMA-IR and both systolic and diastolic blood pressures (r = 0.71 and r = 0.77, respectively). In our study, we showed that patients with primary hypertension have a decreased insulin sensitivity that was reflected in high serum fasting insulin levels. Anti-hypertensive treatment with valsartan increases insulin sensitivity.
