A 3 × 2 factorial arrangements with completely randomized design, with a total of 72 Leghorn Hy-line (W-36) laying hens in the second cycle (98 wk old) of production were randomly assigned to 24 wire cages (45.7×30×30 cm3) and fed with diets containing three levels of guar meal (GM; 0, 4 and 8%) and two levels of β-mannanase (Hemicell®) enzyme (0.00 and 0.05%) for 12 wk period. There...

The molecular mechanisms of hypertriglyceridemia (HTG), a common lipid metabolic disorder in humans, often of genetic origin, are not well understood. In studying the effect of apolipoprotein (apo) E on the metabolism of triglyceride-rich lipoproteins, we found that expressing high plasma levels of human apoE3 in transgenic mice lacking endogenous mouse apoE caused HTG. These transgenic animals...

The anti-hypercholesterolemic effect of berbamine (BBM) isolated from Rhizoma Coptidis (RC) was investigated in hypercholesterolemic zebrafish model induced by high-cholesterol (HC) diet. Zebrafish embryo assay revealed no significant difference in morphology and cell death with the treatment of BBM less than 20 μg/mL. In zebrafish larvae, the fluorescently labeled cholesterol in caudal artery ...

Hyperlipidemia frequently accompanies infectious diseases and may be due to increases in lipoprotein production or decreases in lipoprotein clearance. The administration of endotoxin (LPS) has been used to mimic infection and prior studies demonstrate that LPS produces hypertriglyceridemia. In the present study in rodents, the dose of LPS necessary to induce hyperlipidemia was orders of magnitu...

Teucrium polium is an analgesic, antidiabetic and antilipeidemic herbal medicament. The aim of this survey was to evaluate the effect of aqueous extract T. polium on liver enzymes linked to liver dysfunction, serum lipids and glucose, in diabetic male rats. Methods: A total of 20 Sprague-Dawly male rats became diabetic by intraperitoneal injection of streptozotocin (60 mg/kg). the animals were ...

Normal and streptozotocin-diabetic rats were fed a low carbohydrate diet or one of two high carbohydrate diets (sucrose or starch-bran). High carbohydrate diets were associated with slightly higher plasma glucose levels in both control and diabetic rats. However, glucose tolerance tests were not altered by the diets in either the control or diabetic rats. Plasma and liver triglyceride values fo...

A new experimental approach was used to determine whether a eucaloric, low fat, high carbohydrate diet increases fatty acid synthesis. Normally volunteers consumed low fat liquid formula diets (10% of calories as fat and 75% as glucose polymers, n = 7) or high fat diets (40% of calories as fat and 45% as glucose polymers, n = 3) for 25 d. The fatty acid composition of each diet was matched to t...

PURPOSE OF REVIEW Elevated plasma triglyceride and reduced HDL concentrations are prominent features of metabolic syndrome and type 2 diabetes. Individuals with Tangier disease also have elevated plasma triglyceride concentrations and very low HDL, resulting from mutations in ATP-binding cassette transporter A1 (ABCA1), an integral membrane protein that facilitates nascent HDL particle assembly...
