There is increasing evidence that lipid peroxidation and oxidative modification of low density lipoprotein (LDL) is important in atherogenesis. The present study was designed to study the effects of a single banana meal on plasma lipids and lipoprotein profile, plasma oxidative stress and susceptibility of LDL to oxidation in 20 healthy volunteers. Lipid(More)
The protective effect of rossicaside B, the major phenylpropanoid glycoside from Boschniakia rossica, on CCl(4)-induced hepatotoxicity and the mechanisms underlying its protective effect were investigated. The mice were administered orally with rossicaside B (100 or 200 mg/kg of body weight) 48, 24 and 1 hr before CCl(4) (0.5 ml/kg of body weight)(More)
The present study was undertaken to investigate the hepatoprotective effect of Boschniakia rossica extract (BRE), rich in phenylpropanoid glycoside and iridoid glucoside, on CCl(4)-induced liver damage. Male Wistar rats were randomly divided into six groups of ten each. While the first group was maintained as normal control, groups II-VI were administered(More)
The protective effect of iridoid glucosides from Boschniakia rossica (BRI) against carbon tetrachloride (CCl4)-induced liver injury was examined. CCl4 at a dose of 0.5 ml/kg of body weight was given intraperitoneally to rats to induce liver damage. The rats were sacrificed 16 h after the CCl4 injection. The CCl4 challenge caused a marked increase in the(More)
OBJECTIVE To study the inhibitory effects of soyasaponins on alpha-glucosidase (EC3.2.1.20). METHODS Soyasaponins were isolated by ODS column chromatography and high-performance liquid chromatography (HPLC) from hypocotyls of soybean. The inhibitory activities of each component of soyasaponins against alpha-glucosidase were tested by colorimetric method.(More)
The aim of this study was to investigate the hepatoprotective effect of BRP, a polysaccharide fraction isolated from Boschniakia rossica, against galactosamine and lipopolysaccharide induced fulminant hepatic failure. Mice were injected with a single dose of galactosamine/lipopolysaccharide with or without pretreatment of BRP. Results showed marked(More)
The purpose of this study was to investigate the protective effect of polysaccharides from Boschniakia rossica against hepatotoxicity induced by carbon tetrachloride (CCl4). Boschniakia rossica polysaccharides was administered intragastrically once daily for 7 days. One hour after the final treatment, mice were treated intraperitoneally with 80 mg/kg of(More)
Vascular complications, as a consequence of atherosclerosis, are main causes of morbidity and mortality in patients with diabetes mellitus. There is increasing evidence that lipid peroxidation and oxidative modification of low density lipoprotein (LDL) is important in atherogenesis. In this study we investigated the effect of soybean hypocotyl extract(More)
Purified HLA class II-peptide complexes immobilized to a solid support induce proliferation of human T-cell clones, indicating that human T-cell clones can proliferate in the absence of secondary signals from accessory cells. We hypothesized that T cells can provide co-stimulatory signals to T cells. LFA-1 molecules play an important role in homotypic(More)
Glioblastoma is the most malignant and invasive brain tumor with extremely poor prognosis. p53-inducible gene 3, a downstream molecule of the tumor suppressor p53, has been found involved in apoptosis and oxidative stress response. However, the functions of p53-inducible gene 3(PIG3) in cancer are far from clear including glioblastoma. In this study, we(More)
