Abstract
The automated (AutoAnalyzer II) determination of cholesterol in nine serum pools in the concentration range 3.465-8.871 mmol/l, gave results that were approximately 10% higher than reference values when the analyses were based on unesterified cholesterol standards containing the same amount of water as the sample extracts (1963 analyses in 12 laboratories during a 12 month period; automated value = 0.032 + 1.10 X (Reference value)). A serum calibration procedure was successful ilues, and was equally effective in correcting the values observed for aliquots of 368 fresh-frozen plasma samples analyzed in each of the 12 laboratories during a 38 month period.

Abstract
Abstract
Twelve Lipid Research Clinic laboratories performed automated fluorometric triglyceride analyses on four control serum pools of known concentration by a modified Hantzsch reaction. The analyses were done during a two-year period, with use of common standards, methodology, and quality-control procedures. Estimates of analytical bias, variability, and short- and long-term trends for each instrument and for the entire group of LRC instruments are presented. High accuracy, precision, and interlaboratory comparability were achieved through rigorous standardization and control of the entire analytical procedure. Individual instrument biases varied from an average of 4.9% below to 1.0% above reference values. Between-run variability was often less than within-run variability and interlaboratory variation was substantially less than intralaboratory variation. The total standard deviation for all instruments ranged from 37 to 63 mg/liter. Only 5 to 14% of this variation was due to differences among instruments. The among-instruments standard deviation ranged from 12 to 17 mg/liter; the between-run, within-instrument standard deviation ranged from 29 to 46 mg/liter, and within-run standard deviation from 27 to 40 mg/liter. The significance of the results for long-term collaborative studies is discussed.

Abstract
The ability of cultured human arterial smooth muscle cells to regulate low density lipoprotein (LDL) receptor activity was tested. In contrast to human skin fibroblasts incubated with lipoprotein deficient medium under identical conditions, smooth muscle cells showed significantly reduced enhancement of 125I-labeled LDL and 125I-labeled VLDL (very low density lipoprotein) binding. Smooth muscle cells also failed to suppress LDL receptor activity during incubation with either LDL or cholesterol added to the medium, while fibroblasts shoed an active regulatory response. Thus, in comparison with the brisk LDL receptor regulation characteristic of skin fibroblasts, arterial smooth muscle cells have and attenuated capacity to regulate their LDL receptor activity. These results may be relevant to the propensity of these cells to accumulate LDL and cholesterol and form "foam cells" in the arterial wall in vivo, a process associated with atherogenesis.

Abstract
In order to elucidate the mechanism(s) of hyperlipidemia following glucocorticoid administration, dexamethasone (0.125 mg/Kg) was administered daily intramuscularly for 2 wk to male Sprague-Dawley rats and the effects on plasma triglyceride (TG) and cholesterol (Chol), lipoprotein neutral lipids, hepatic triglyceride secretion rates (TGSR; Triton), and epididymal fat lipoprotein lipase (LPL) were determined. Special measures were taken to maintain positive caloric balance and keep the weights of control and dexamethasone-treated animals comparable. Significant increases (p less than 0.001) in TG and very-low density lipoprotein (VLDL) triglyceride associated with no change in Chol and actual reduction in both triglyceride and cholesterol in low density lipoprotein (ldl) were observed in the steroid-treated animals. Dexamethasone treatment was associated with increased basal insulin and glucose levels, an insignificant increment in TGSR, and a highly significant reduction (p less than 0.001) in LPL. These findings suggest that glucocorticoid treatment increases splanchnic triglyceride production rates, but the resulting hypertriglyceridemia is primarily a consequence of impaired VLDL removal due to low adipose tissue LPL activity.

Abstract
Since quantitative and qualitative alterations in plasma lipoproteins may provide insights into mechanism(s) of altered lipid transport in renal failure, whole plasma triglyceride (TG) and cholesterol (Chol) concentrations and lipoprotein neutral lipids and composition were examined in patients with chronic renal failure (undialyzed and dialyzed) and following successful renal transplantation. Both uremic groups demonstrated increased TG (p less than 0.001) and normal Chol in whole plasma and increased total TG and Chol in the very low-density lipoprotein fraction (VLDL). All hyperlipidemic subjects showed a Type IV phenotype. The percentage triglyceride in VLDL was slightly higher than control in the dialysis patients, and significantly increased in LDL in both undialyzed (p less than 0.001) and dialyzed (p less than 0.005) uremic groups. Transplant patients had significant increases (p less than 0.001) in both TG and Chol in whole plasma, and increased total TG and Chol in both the low-density lipoproteins (LDL) and VLDL fractions. Transplant patients with hyperlipidemia showed a variety of phenotypes and an enrichment of triglyceride in VLDL and LDL. These findings indicate that abnormalities in lipoprotein metabolism in renal failure patients are not appreciably affected by chronic dialysis treatment and continue following successful transplantation. The tendency toward increased VLDL and LDL triglyceride content in these patients resembles the lipoprotein neutral lipid composition found in nonrenal patients with similarly elevated plasma lipids. These alterations could result from primary disturbances in VLDL production and/or removal.
