We determined the urinary excretion, expressed as the protein/creatinine ratio (morning urines), of albumin (a marker of glomerular dysfunction) and retinol-binding protein (RBP; a low-molecular-mass protein marker of tubular proteinuria) in 102 non-insulin-dependent diabetic patients. There was a statistically significant (P < 0.0001) correlation (rho = 0.38) between the urinary excretion valu...

The urinary extraction of albumin, retinol binding protein, and N-acetyl-beta-D-glucosaminidase were studied in 60 children with insulin dependent diabetes mellitus and in 45 normal children to find out whether the renal tubules played a part in causing the early increase in urinary excretion of albumin that occurs in diabetes mellitus. Two overnight urine samples were collected and the protein...

The assay characteristics of a new radioimmunoassay kit for determining urinary albumin at low concentrations were studied. The sensitivity for urinary albumin was 2 mg/l, the analytical range 2 to 40 mg/l, and interassay coefficient of variation less than 12%. In a method comparison study entailing diabetic urine samples covering an albumin concentration of 2 to 150 mg/l the kit compared adequ...

Urinary protein excretion was measured before and after the intravenous infusion of lysine in 14 normal subjects after 4-6 days' acclimatization at 4846 m. Urinary albumin excretion before lysine was elevated in 11 subjects but alpha 1-microglobulin was detected in only four. After lysine a large increase in albumin excretion occurred in all subjects. Together with the absence of alpha 1-microg...

Objective: To assess growth arrest-specific 6 (Gas6) protein as a biomarker of glomerular damage (glomerulopathy; nephropathy) in patients with sickle cell anaemia (SCA). Methods: seventy SCA on routine clinic visit and apparently healthy controls were recruited into the study their blood urine samples collected while plasma Gas6 well urinary albumin creatinine measured. Their socio-demographic...

OBJECTIVE To demonstrate that the administration of an angiotensin (Ang) II type 1 receptor (AT1R) blocker (ARB) inhibits the vicious cycle of high glucose (HG)-reactive oxygen species (ROS)-angiotensinogen (AGT)-Ang II-AT1R-ROS by suppressing ROSs and inflammation, thus ameliorating diabetic nephropathy (DN). RESEARCH DESIGN AND METHODS Thirteen hypertensive DN patients were administered ARB...

clear account of the microscopic examination of the sediment, which are also well illustrated in the plates at the end of the book. Then comes the qualitative chemical examination of albumin, other urinary proteids, mucin, blood, chyluria, sugar, bile, &c. The following sections deal with the quantitative examination of albumin, glucose, urea, phosphates, &c., and this is followed by a brief an...
