Suitable Animal Model

Adult male Syrian hamsters were fed on a high-fat diet with or without access to boiled coffee. Plasma total, low-density-lipoprotein- and high-density-lipoprotein-cholesterol and triacylglycerol concentrations were increased by the coffee and very-low-density-lipoprotein-cholesterol concentrations were lowered. It is concluded that the Syrian hamster is a suitable animal model in which to study the hypercholesterolaemic effect of coffee

Background/Aim. C-reactive protein is an independent predictor of the risk of cardiovascular events and diabetes mellitus in apparently healthy men. The relationship between C-reactive protein and the features of metabolic syndrome has not been fully elucidated. To assess the cross-sectional relationship between C-reactive protein and the features of metabolic syndrome in healthy people. Methods. We studied 161 military pilots (agee, 40?6 years) free of cardiovascular disease, diabetes mellitus and active inflammation on their regular annual medical control. Age, total cholesterol, low density lipoprotein cholesterol, high density lipoprotein cholesterol, triglycerides, fasting glucose, glycosylated hemoglobin, blood pressure, smoking habit, waist circumference and body mass index were evaluated. Plasma C-reactive protein was measured by the immunonephelometry (Dade Behring) method. Metabolic syndrome was defined according to the National Cholesterol Education Program Expert Panel. Results. The mean C-reactive protein concentrations in the subjects grouped according to the presence of 0, 1, 2 and 3 or more features of the metabolic syndrome were 1.11, 1.89, 1.72 and 2.22 mg/L, respectively (p = 0.023) with a statistically, significant difference between those with 3, and without metabolic syndrome (p = 0.01). In the simple regression analyses C-reactive protein did not correlate with the total cholesterol, low density lipoprotein cholesterol, high density lipoprotein cholesterol, body mass index and blood pressure (p > 0.05). In the multiple regression analysis, waist circumference (? = 0.411, p = 0.000), triglycerides to high density lipoprotein cholesterol ratio (? = 0.774, p = 0.000), smoking habit (? = 0.236, p = 0.003) and triglycerides (? = 0.471, p = 0.027) were independent predictors of C-reactive protein. Conclusions. Our results suggested a cross-sectional independent correlation between the examined cardiovascular risk factors as the predominant features of metabolic syndrome and C-reactive protein in the group of apparently healthy subjects. The lack of correlation of C-reactive protein with the total cholesterol and low density lipoprotein cholesterol in our study may suggest their different role in the process of atherosclerosis and the possibility to determine C-reactive protein in order to identify high-risk subjects not identified with cholesterol screening.

1. Increased blood or plasma viscosity has been observed in almost all conditions associated with accelerated atherosclerosis. Cognizant of the enlarging body of evidence implicating increased viscosity in atherogenesis, we hypothesize that the effects of low-density lipoprotein and high-density lipoprotein on blood viscosity correlate with their association with risk of atherosclerosis. 2. Blood viscometry was performed on samples from 28 healthy, non-fasting adult volunteers using a capillary viscometer. Data were correlated with haematocrit, fibrinogen, serum viscosity, total cholesterol, high-density lipoprotein-cholesterol, triglycerides and calculated low-density lipoprotein-cholesterol. 3. Low-density lipoprotein-cholesterol was more strongly correlated with blood viscosity than was total cholesterol (r = 0.4149, P = 0.0281, compared with r = 0.2790, P = 0.1505). High-density lipoprotein-cholesterol levels were inversely associated with blood viscosity (r = −0.4018, P = 0.0341). 4. To confirm these effects, viscometry was performed on erythrocytes, suspended in saline, which had been incubated in plasma of various low-density lipoprotein/high-density lipoprotein ratios. Viscosity correlated directly with low-density lipoprotein/high-density lipoprotein ratio (n = 23, r = 0.8561, P < 0.01). 5. Low-density lipoprotein receptor occupancy data suggests that these effects on viscosity are mediated by erythrocyte aggregation. 6. These results demonstrate that the effects of low-density lipoprotein and high-density lipoprotein on blood viscosity in healthy subjects correlate with their association with risk of atherosclerosis. These effects on viscosity may play a role in atherogenesis by modulating the dwell or residence time of atherogenic particles in the vicinity of the endothelium.

Objective: To compare serum levels of total cholesterol, triglycerides, low density lipoprotein cholesterol and high density lipoprotein cholesterol between broilers and laying hens. Materials and Methods: the present is a cross study, descriptive and analytic. Data was analyzed using simple ANOVA, the program Statgraphics Plus 5.1 was used. The study was performed at Universidad de Caldas in Manizales (Colombia). After fasting, blood from 30 broilers (Cobb 500 line) of 35-day-old and 40 laying hens (Hy-Line W-36 line) of 26-weeks-old. Serum levels of triglycerides, total cholesterol, low density lipoprotein cholesterol and high density lipoprotein cholesterol was measured by enzymatic colorimetric methods, direct method (detergent + N,Nbis (4-sulfobutyl)-m-toluidine) was used for the lipoprotein cholesterol. Results: Between broilers (Cobb 500 line) and (laying hens (Hy-line W-36 line) was significant difference in serum levels of triglycerides and in serum levels of high density lipoprotein cholesterol (P <0.05); serum levels of total cholesterol and serum levels of low density lipoprotein cholesterol, no differences were found (P> 0.05) Conclusions: Despite differences in gender, age, and production system among broilers Cobb 500 line and laying hens Hy-Line W-36, no differences were found between serum total cholesterol and low density lipoprotein cholesterol.
