25. Beta 2-glycoprotein-1 (apolipoprotein H) excretion and renal tubular malfunction in diabetic patients without clinical proteinuria.
AIM--To compare the urinary excretion of beta 2-glycoprotein-1 with that of two other markers of early tubular disorder in diabetic patients without clinical proteinuria. METHODS--The urinary excretion of retinol binding protein, beta 2-glycoprotein-1, and N-acetyl-beta-D-glucosaminidase was measured in 90 known diabetic patients who had a negative reagent s

26. Is low proteinuria an early predictor of severity of acute pancreatitis?
Serial six hourly urine collections were made for seven days on 20 patients with acute pancreatitis. Quantitative immunoassay of urinary albumin and IgG on the first urine sample after admission showed increased excretion rates in 14 and 13 patients, respectively. Urinary protein excretion rates remained normal or approached normal by seven days in 17 patien

27. Glomerular filtration and tubular reabsorption of albumin in preproteinuric and proteinuric diabetic rats.
Microalbuminuria (26-250 mg/d) is considered to be an indicator of incipient diabetic nephropathy in humans in insulin-dependent diabetes (IDD). However, before microalbuminuria is observed, glomerular alterations, such as glycosylation of the glomerular basement membrane and glomerular hyperfiltration, in IDD may result in increased filtration of albumin be

28. Urinary excretion of beta 2-glycoprotein-1 (apolipoprotein H) and other markers of tubular malfunction in "non-tubular" renal disease.
AIM: To determine whether urinary beta 2-glycoprotein-1 assays can provide improved discrimination between chronic renal diseases which are primarily of tubular or glomerular origin. METHODS: Urinary beta 2-glycoprotein-1, retinol-binding protein, alpha 1-microglobulin, beta 2-microglobulin, N-acetyl-beta-D-glucosa-minidase and albumin were measured in 51 pa

29. Differentiation of glomerular, tubular, and normal proteinuria: determinations of urinary excretion of β2-microglobulin, albumin, and total protein
A low molecular weight β2-globulin (β2-microglobulin), albumin, and total protein were measured in concentrated 24-hr urine specimens from 20 healthy subjects and 30 patients with clinical proteinuria of glomerular or tubular type. Classification of proteinuria was made on the basis of clinical diagnosis and size distribution of urinary proteins after gel

32. Use of 125I- and 51Cr-Labeled Albumin for the Measurement of Gastrointestinal and Total Albumin Catabolism*
A method for the simultaneous measurement of gastrointestinal protein loss and total albumin turnover entailing the use of a combination of 125iodine- and 51chromium-labeled albumin is described. Albumin turnover was calculated by the measurement of albumin-125I plasma decay and cumulative urinary excretion, and the results obtained agreed closely with previ

33. Effect of protein restriction in insulin dependent diabetics at risk of nephropathy.
Persistent proteinuria is strongly associated with increased mortality in insulin dependent diabetes, and risk of this condition can be predicted many years in advance by subclinical increases in albumin excretion rate (microalbuminuria). Eight normotensive insulin dependent diabetics with microalbuminuria who had overnight albumin excretion rates of between

35. A Comparison of the Segmental Analysis of Sodium Reabsorption during Ringer's and Hyperoncotic Albumin Infusion in the Rat
Studies were designed to compare the segmental analysis of sodium reabsorption along the nephron during volume expansion with either 10% body weight Ringer's or 0.6% body weight hyperoncotic albumin. Total kidney and nephron glomerular filtration rate increased similarly with both, but urinary sodium excretion (12.7 vs. 4.0 μeq/min, P < 0.001) and fractiona

36. Chronic metabolic acidosis decreases albumin synthesis and induces negative nitrogen balance in humans.
Chronic metabolic acidosis has been previously shown to stimulate protein degradation. To evaluate the effects of chronic metabolic acidosis on nitrogen balance and protein synthesis we measured albumin synthesis rates and urinary nitrogen excretion in eight male subjects on a constant metabolic diet before and during two different degrees of chronic metabol
