| screening of vasorelaxant activity of some medicinal plants used in oriental medicines. | hexane, ethylacetate (etoac), and n-butanol (n-buoh) extracts of medicinal plants traditionally used in the east asia, such as china, korea, and japan were screened for their vasorelaxant activity using isolated rat aorta. among the 60 solvent-extracts from 20 medicinal plants, hexane and n-buoh extracts of diospyros kaki and polygonum aviculare, hexane, etoac, and n-buoh extracts of magnolia liliflora, n-buoh extract of sorbus commixta, and etoac and n-buoh extracts of selaginella tamariscina w ... | 2005 | 15848029 |
| phytoremediation of heavy-metal-polluted soils: screening for new accumulator plants in angouran mine (iran) and evaluation of removal ability. | heavy metal pollution is a worldwide problem. phytoremediation is an effective and low-cost interesting technology. this study was conducted in a dried waste pool of a lead and zinc mine in angouran (iran) to find accumulator plant(s). concentrations of heavy metals were determined both in the soil and the plants that were grown in the mine and out of mine. the concentration of total cu, fe, zn, pb and ni in the mine area were higher than the control soil. the results showed that five dominant v ... | 2009 | 19386362 |
| phytoremediation of petroleum-polluted soils: application of polygonum aviculare and its root-associated (penetrated) fungal strains for bioremediation of petroleum-polluted soils. | petroleum-polluted soils are a common disaster in many countries. bioremediation of oil contamination in soils is based on the stimulation of petroleum-hydrocarbon-degrading fungal and microbial communities. a field study was conducted in a petroleum-contaminated site to find petroleum-resistant plants and their root-associated fungal strains for use in bioremediation of petroleum-polluted soils. results and observations showed that the amounts of petroleum pollution in nonvegetated soils were s ... | 2010 | 19932506 |
| screening of natural antioxidants from traditional chinese medicinal plants associated with treatment of rheumatic disease. | in order to find new sources of natural antioxidants, the antioxidant capacities of 50 medicinal plants associated with treatment of rheumatic diseases were systemically evaluated using the ferric-reducing antioxidant power (frap) and trolox equivalent antioxidant capacity (teac) assays, and their total phenolic contents were measured by the folin-ciocalteu method. their antioxidant activities of some of these plants were analyzed for the first time. the frap and teac assay results suggested tha ... | 2010 | 20877204 |
| screening of herbal medicines for recovery of acetaminophen-induced nephrotoxicity. | this study was conducted to quantitatively evaluate the recovery effects of herbal medicines on acetaminophen-induced nephrotoxicity. in the present study, the recovery effects of 251 herb medicines on hek 293 cells that had been damaged by acetaminophen were evaluated using an mts assay. hek 293 cells were cultured in 96-well plates and then pretreated with or without 20++m acetaminophen (ic(50) value: 17.5-¦1.9) for 1h. next, different herbal medicines were added to the wells, after which the ... | 2009 | 21783944 |
| effects of polygonum aviculare herbal extract on sperm parameters after emf exposure in mouse. | electromagnetic fields with high energy same as ionizing radiation inserts their destructive effects via free radical production. using antioxidants or herbal plants with antioxidants components could diminish hazardous effects of emf. polygonum aviculare has a high amount of phenolic and flavonoid and proved that has antioxidants effects. the aim of this study was to evaluate the effects of polygonum aviculare herbal extract on sperm parameters after emf exposure in mouse. twenty four male mice ... | 2011 | 22308654 |
| antimicrobial activity and phytochemical analyses of polygonum aviculare l. (polygonaceae), naturally growing in egypt. | polygonum aviculare (polygonaceae) is an herb commonly distributed in mediterranean coastal regions in egypt and used in folkloric medicine. organic and aqueous solvent extracts and fractions of p. aviculare were investigated for antimicrobial activities on several microorganisms including bacteria and fungi. phytochemical constituents of air-dried powered plant parts were extracted using aqueous and organic solvents (acetone, ethanol, chloroform and water). antimicrobial activity of the concent ... | 2010 | 23961059 |
| identification of magnolia officinalis l. bark extract as the most potent anti-inflammatory of four plant extracts. | this study was designed to compare the anti-inflammatory potential of a magnolia officinalis l. bark extract solely or in combination with extracts prepared from either polygonum aviculare l., sambucus nigra l., or isodon japonicus l. in bacterial lipopolysaccharide (lps) stimulated human gingival fibroblasts (hgf-1) and human u-937 monocytes, as cell models of periodontal disease. hgf-1 and u-937 cells were incubated with lps from either porphyromonas gingivalis or escherichia coli together wit ... | 2013 | 23711140 |
| tillage and residue burning affects weed populations and seed banks. | an integrated weed management approach requires alternative management practices to herbicide use such as tillage, crop rotations and cultural controls to reduce soil weed seed banks. the objective of this study was to examine the value of different tillage practices and stubble burning to exhaust the seed bank of common weeds from the northern grain region of australia. five tillage and burning treatments were incorporated in a field experiment, at armidale (30 degrees 30's, 151 degrees 40'e), ... | 2006 | 17390813 |
| variation in weed seed fate fed to different holstein cattle groups. | weed seeds may maintain their viability when passing through the digestive tract of cattle and can be therefore dispersed by animal movement or the application of manure. whether different cattle types of the same species can cause differential weed seed fate is largely unknown to us particularly under non-grazed systems similar to holstein-friesian dairy farming. we investigated the effect on the seed survival of four weed species in the digestive tracts of four groups of holstein cattle: lacta ... | 2016 | 27104783 |
