To investigate the effect of metformin on insulin receptor binding and diabetic control, eight obese type II diabetic patients were studied before treatment, after one and four weeks of taking metformin (500 mg thrice daily), and four weeks after withdrawal of the drug. After one and four weeks of treatment the number of erythrocyte insulin receptors had increased by 116% and 184% respectively....

A comparison of methods, two based upon 5-hydroxymethylfurfural determination (colorimetric using a semi-automated procedure and HPLC) and ion exchange chromatography (HbA1 using BioRad method) was performed. The influence of variables on 5-hydroxymethylfurfural determination is reported. The dialysis step appears to be essential for an accurate determination of 5-hydroxymethylfurfural released...

To determine the prevalence and extent of autonomic neuropathy amongst Africans with insulin-dependent diabetes mellitus (IDDM), we investigated 50 such patients at our clinic. Mean age (+/- 1 s.d.) was 26 +/- 6 years, male:female ratio was equal (25M:25F) and duration of diabetes was 4.0 +/- 3.0 years. A battery of six validated tests of autonomic function was performed, testing both sympathet...

Alpha-thalassemia (α-thal) is a disorder caused by the deletion of single or double α-globin genes, and/or point mutations in the α-globin genes. There are 2 common types of α-globin genes; HBA2 and HBA1. Recently, it has been discovered that the HBA2 gene is replaced by a unique HBA12 gene convert in 5.7% of the Saudi population. The α-globin genes have been emerging as a molecular target for ...

The predictive value of three parameters (amniotic fluid insulin and C-peptide, and HbA1) in prognosticating major neonatal symptomatology was investigated in 57 pregnancies of diabetic women. The prediction of a healthy neonate can be achieved with a 90% accuracy by measurement of the amniotic fluid insulin alone. The correct prognosis for a child with major neonatal problems due to maternal d...

Methods The electronic case records of total of 7,418 diabetic patients who were seen in the diabetes clinic at St Thomas’ Hospital between 1979 and 1998 were selected for this study. All of these patients were registered with a standardised structured ‘First Visit’ history and examination on a computerised diabetes clinical records system – Diabeta and had a mean of 12 years of follow-up. The ...

OBJECTIVE This study examined predictive and mediated relationships among youth perception of critical parenting, Child Behavior Checklist Externalizing Subscale (CBCL) externalizing problem scores, adherence, and (hemoglobin A(1c) HbA(1c)), in youth with type 1 diabetes from low socioeconomic status families. METHODS Caregiver/youth dyads (n = 120) completed diabetes specific measures of fam...

The present study was undertaken to evaluate the possible protective effects of simvastatin (SMV) against oxidative stress in streptozotocin- (STZ)-induced diabetic rats. Diabetes was induced experimentally in rats by i.p. injection of STZ in a dose of 60 mg/kg bwt. After 5 weeks of STZ injection, there were apparent reductions in the animal body weight and significant increase in blood glucose...

OBJECTIVE To evaluate whether insulin pump therapy [continuous subcutaneous insulin infusion (CSII)] is associated with a lower frequency of disordered eating, better glycemic control, and improved quality of life and self-efficacy compared to multiple daily injections (MDI) in adolescent females with type 1 diabetes mellitus (T1DM). METHODS This cross-sectional study included 22 adolescent f...
