lead and other elements in tissues of guinea pigs fed crown vetch grown adjacent to a highway.	forty-four elements were determined in crown vetch sampled along a heavily travelled highway in virginia. twenty-four elements including ba, br, cr, pb, sn, and sr were higher in this vegetation than in control vetch. when the highway-grown vetch was fed as 45% (dry weight) of the diet to guinea pigs for 100 days, ba, br, cr, pb, sn and sr were found at higher concentrations in the various animal tissues than in those of guinea pigs similarly fed the control crown vetch.	1978	81734
lead in tissues of woodchucks fed crown vetch growing adjacent to a highway.	woodchucks (marmota monax) were fed crown vetch (coronilla varia) growing along a major highway that was harvested in 1979, before unleaded gas was widely used, and again in 1985. crown vetch, harvested 300 m from the nearest road, was fed as the control. the crops were fed as 50% dry weight of the diet for 58 d. the concentrations of lead in the control, 1979 crop, and 1985 crop were, respectively, 0.74, 50.65, and 6.78 ppm dry weight. the average +/- se) concentrations (ppm, dry weight) of lea ...	1986	2427733
vicia tetrasperma (four-seeded vetch) ingestion by a 3-year-old child.	we report an ingestion of vicia tetrasperma (four-seeded vetch), initially misidentified as crown vetch (coronilla varia). vicia tetrasperma is not listed in poisindex; little is known of its toxic effects and we found no published human case reports. the child suffered only minor gastrointestinal effects which lasted a few hours and had no residual effects upon 24- and 96-hour followups.	1993	8249267
changes in total and individual proteins during drying, ensiling, and ruminal fermentation of forages.	effects of wilting, drying, and ensiling on concentrations of proteins in alfalfa, crown vetch, perennial ryegrass, orchardgrass, and tall fescue were studied using sds-page. seven to nine proteins were identified in the samples. wilting forages for 24 h on a laboratory bench had little effect on the relative amounts of proteins. drying forage (on a laboratory bench) for 5 d resulted in a 25 to 30% loss in electrophoretically identified proteins. a 45-kda protein was more susceptible to hydrolys ...	1994	8182173
characterization of condensed tannins purified from legume forages: chromophore production, protein precipitation, and inhibitory effects on cellulose digestion.	to identify simple screening tools for selecting condensed tannin (ct)-containing forages as candidate sources for further study, ct were isolated from nine legumes, and their molecular weights (mw), chromophore production, capacity to precipitate bovine serum albumin (bsa) and fraction 1 protein (rubisco) isolated from alfalfa, and inhibition of filter paper digestion were compared. sources were as follows: leaves of sericea lespedeza (lespedeza cuneata dum.-cours.), crown vetch (coronilla vari ...	2005	16132212
choice of hydrogen uptake (hup) status in legume-rhizobia symbioses.	the h(2) is an obligate by-product of n-fixation. recycling of h(2) through uptake hydrogenase (hup) inside the root nodules of leguminous plants is often considered an advantage for plants. however, many of the rhizobium-legume symbioses found in nature, especially those used in agriculture are shown to be hup(-), with the plants releasing h(2) produced by nitrogenase activity from root nodules into the surrounding rhizosphere. recent studies have suggested that, h(2) induces plant-growth-promo ...	2012	23139886
