Antioxidative activity of green tea polyphenol in cholesterol-fed rats.
Green tea polyphenol may exert an antiatherosclerotic action by virtue of its antioxidant properties and by increasing HDL cholesterol levels by increasing high-density lipoprotein cholesterol levels. Expand
Direct scavenging of nitric oxide and superoxide by green tea.
It is confirmed that green tea tannin has excellent antioxidant properties, which may be involved in the beneficial effect of this compound, and the O-trihydroxy structure in the B ring is an important determinant of such activity. Expand
Protective activity of green tea against free radical- and glucose-mediated protein damage.
It was found that green tea extract can effectively protect against protein damage, and showed that its action is mainly due to tannin, demonstrating the mechanisms of the usefulness of green tea in protein oxidation- and glycation-associated diseases. Expand
The effects of Coptidis Rhizoma extract on a hypercholesterolemic animal model.
Results indicate that Coptidis Rhizoma extract is effective in reducing the pathological damage caused by hypercholesterolemia, through lowering of serum cholesterol levels and the serum thiobarbituric acid-reactive substance level decreased after oral administration. Expand
Astaxanthin ameliorates features of metabolic syndrome in SHR/NDmcr-cp.
It is suggested that dietary astaxanthin oil (ASX-O) ameliorates insulin resistance by mechanisms involving the increase of glucose uptake, and by modulating the level of circulating lipid metabolites and adiponectin. Expand
Inhibitory effects of Luobuma tea and its components against glucose-mediated protein damage.
Strong inhibitory activity against the formation of AGEs was shown by Luobuma aqueous extract and may help to explain the beneficial effects of this plant against atherosclerosis. Expand
Cinnamaldehyde induces endothelium-dependent and -independent vasorelaxant action on isolated rat aorta.
Results suggested that the vasorelaxant effects of cinnamaldehyde were derived from both endothelium-dependent and -independent effects, and one of the mechanisms of endothelia-independent relaxation is thought to be influenced by the blocking of Ca2+ channels. Expand
Influence of green tea polyphenol in rats with arginine-induced renal failure.
To determine whether green tea polyphenol ameliorates the pathological conditions induced by excessive dietary arginine, green tea polyphenol was administered to rats at a daily dose of 50 or 100Expand
Therapeutic usefulness of Keishi‐bukuryo‐gan for diabetic nephropathy
The potential therapeutic usefulness of Keishi‐bukuryo‐gan for retarding the progression of renal damage is indicated and it is suggested that its beneficial effects were due to its ability to improve metabolic abnormalities associated with diabetes. Expand
Oren-gedoku-to and Keishi-bukuryo-gan-ryo inhibit the progression of atherosclerosis in diet-induced hypercholesterolemic rabbits.
The results suggest that OGT and KBG prevent the progression of atheromatous plaque by creating a sounder antioxidant defense system than vitamin E. Expand
