Physalis peruviana L. (PP) is a popular folk medicine used for treating cancer, leukemia, hepatitis, rheumatism and other diseases. In this study, our objectives were to examine the total flavonoid and phenol content of different PP extracts (aqueous: HWEPP; ethanolic: EEPP; supercritical carbon dioxide: SCEPP-0, SCEPP-4 and SCEPP-5) and their(More)
1. Cinnamaldehyde has been shown to be effective in inducing cell apoptosis in a number of human cancer cells. The aim of the present study was to investigate the effect of vitamin E on the apoptotic signalling mechanism induced by cinnamaldehyde in human hepatoma PLC/PRF/5 cells. 2. Using the XTT assay, cinnamaldehyde exhibited a powerful antiproliferative(More)
We have induced callus tissues from one R6/R6 homozygous genotype red-fleshed apple individual which was the hybrid offspring of Malus sieversii f.niedzwetzkyana and ‘Fuji’, and investigated the effect of auxin alone and auxin combined with cytokinin or nitrogen deficiency on anthocyanin synthesis. In callus culture, auxin alone significantly inhibited(More)
To explore the effects of angiotensin-converting enzyme (ACE) inhibitors on endothelial dysfunction induced by homocysteine thiolactone (HTL). Both endothelium-dependent relaxation and nondependent relaxation of thoracic aortic rings in rats induced by acetylcholine (Ach) or sodium nitroprusside (SNP) and biochemical parameters including malondialdehyde(More)
Armillariella mellea (AM), also known as Mi-Huan-Ku, a popular medicinal fungus used in the traditional Chinese medicine for treating headache, neurasthenia and insomnia. In the present study, our aim was to determine the effects of aqueous (AAM) and ethanol (EAM) extracts of A. mellea on lipopolysaccharide (LPS)-induced inflammatory response by measuring(More)
Tetrandrine (TET), a bis-benzylisoquinoline alkaloid isolated from the dried root of hang-fang-chi (Stephania tetrandra S. Moore), is traditionally used in China for treating inflammation, hypertension and silicosis. In this study, our aim was to examine the anti-inflammatory mechanism of TET through measuring the inducible nitric oxide synthase (iNOS),(More)
Tocotrienol-rich fraction (TRF) of palm oil has been shown to possess potent antioxidant, anticancer, and cholesterol lowering activities. In this study, our aim was to examine the effects of TRF on LPS-induced inflammatory response through measuring the production of inflammatory mediators, namely nitric oxide (NO), prostaglandin E(2) (PGE(2)), inducible(More)
Cinnamaldehyde (Cin) has been shown to be effective in inducing apoptotic cell death in a number of human cancer cells. However, the intracellular death signaling mechanisms by which Cin inhibits tumor cell growth are poorly understood. In this study, we investigated the effect of mitogen-activated protein kinases (MAPKs) inhibitors [namely SP600125 (a(More)
To explore detrimental effects of advanced oxidation protein products-bovine serum albumin (BSA) on endothelial function and compare the favorable effects of angiotensin-converting enzyme (ACE) inhibitors: captopril and enalapril. Male Sprague-Dawley rats were randomly divided into groups: control, advanced oxidation protein products-BSA, captopril (10, 20(More)
Physalis species is a popular folk medicine used for treating cancer, leukemia, hepatitis and other diseases. Studies have shown that the ethanol extract of Physalis peruviana (EEPP) inhibits growth and induces apoptotic death of human Hep G2 cells in culture, whereas proliferation of the mouse BALB/C normal liver cells was not affected. In this study, we(More)
