The effects of dietary bitter melon (Momordica charantia) freeze-dried powder on serum glucose level and lipid parameters of the serum and liver were studied in rats fed diets supplemented with and without cholesterol. Rats were fed the diets for 14 days containing bitter melon freeze-dried powder at the level of 0.5, 1 and 3% without an added dietary(More)
The objective of this study was to compare the effects of dietary soy protein isolate and casein on atherosclerotic lesion development in apolipoprotein (apo) E-deficient mice. Male C57BL/6J apoE-deficient mice (9-10 wk old) in groups of 6-9 were used in a series of feeding studies. In the first experiment, mice were fed purified diets containing(More)
The effects of taurine on hepatic cholesterol metabolism were investigated in hamsters fed a high-fat diet or normal chow. Two weeks-treatment of taurine at 1% in drinking water prevented high-fat diet-induced increase in cholesterol levels of serum and liver. The decrease in serum cholesterol by taurine was due to decrease in non-HDL cholesterols. A(More)
The effects of dietary taurine on lipid secretion and ketone body production were examined in the livers of Wistar and Sprague-Dawley rats fed high-cholesterol diets. The weight gain of the Sprague-Dawley rats tended to be higher than that of the Wistar rats, although food intake was comparable between the strains. The concentration of hepatic triglyceride(More)
The effects of taurine supplementation on the serum cholesterol levels and the progression of atherosclerosis were investigated in the hyperlipidemia- and atherosclerosis-prone Japanese (LAP) quail. The ingestion of a high-cholesterol diet containing 1% cholesterol by LAP quails for 60 days resulted in a marked elevation in serum non-HDL cholesterol and(More)
Early responses of cholesterol metabolism to dietary cholesterol were compared between exogenous hypercholesterolemic (ExHC) and Sprague-Dawley rats. Both strains had a similar radioactivity of [14C]cholesterol in the serum half a day after the oral administration, but thereafter the radioactivity disappeared slowly in ExHC rats. ExHC rats promptly altered(More)
Various fatty acids are attracting considerable interest for their anticancer effects. Among them, fatty acids containing conjugated double bonds show one of the most potent cytotoxic effects on cancer cells. Here, we focused on the cancer cell killing activity of jacaranda seed oil. The seed oil of jacaranda harvested from Miyazaki in Japan contained 30.9%(More)
The effect of ethanolamine plasmalogen (EtnPm) on lipid peroxidation was investigated in liposomal suspension of egg yolk phosphatidylcholine. EtnPm inhibited iron- and copper-dependent peroxidation in the presence of preformed hydroperoxides, although it was not effective for radical initiator mediated lipid peroxidation. EtnPm resulted in complete binding(More)
A study was carried out to examine if the positional distribution of medium chain fatty acids (MCF) in triacylglycerol influences dietary fat absorption in rats. Two types of structure-specific fats, one predominantly composed of MCF in sn-1(3) and iinoleic acid in sn-2 [sn1(3)MCF-structured] and the others of MCF in sn-2 and linoleic acid in sn-1(3)(More)
The effects of dietary conjugated linoleic acid (CLA) and linoleic acid (LA) on ketone body production and lipid secretion were compared in isolated perfused rat liver. After feeding the 1% CLA diet for 2 wk, the concentration of post-perfused liver cholesterol was significantly reduced by CLA feeding, whereas that of triacylglycerol remained unchanged.(More)
