| [diagnostic use of enzymatic rast skin tests and determination of eosinophils in nasal mucosa in allergic rhinitis]. | allergic rhinitis is the most frequent disease mediated by immunoglobulin e (ige). nasal challenge is the gold standard for the diagnosis of allergic rhinitis. skin tests (st) are the most used diagnostic method to detect the presence of specific ige bind to skin mast cells. the exposition of the nasal mucous membrane to the allergen is followed by an increase of the local eosinophils; the count of eosinophils in nasal mucous (enm) is a diagnostic test for allergic rhinitis. enzymatic rast or en ... | 1998 | 9951327 |
| voluntary intake, digestibility, and subsequent selection of matua bromegrass, coastal bermudagrass, and alfalfa hays by yearling horses. | matua bromegrass (bromus willdenowii kunth. cv. grasslands matua) was introduced in 1973, but little information exists concerning its potential as a hay for horses. thus, voluntary intake and apparent digestibility of om, cp, and fiber components of matua by 18 quarter horse yearlings (mean initial bw 354 kg; se 5.8) were compared with alfalfa (medicago sativa l.) and coastal bermudagrass (cynodon dactylon l.) as hays in a randomized block design. a 15-d adjustment period was followed by a 5-d ... | 1999 | 10521039 |

| isolation and partial characterization of a 46-kd allergen of bermuda grass pollen. | cyn d bd46k, a 46-kd component of bermuda grass (cynodon dactylon) pollen, had been identified as an allergenic constituent. in the present study two-dimensional (2d) gel electrophoresis illustrated the presence of five acidic isoforms in cyn d bd46k, and this molecule was purified by monoclonal antibody (mab) affinity chromatography for further characterization. using a digoxigenin-labeled lectin-binding assay, the elucidating protein was disclosed to be a glycoprotein with terminal mannose. th ... | 2001 | 11455197 |
| phosphorus and ammonium concentrations in surface runoff from grasslands fertilized with broiler litter. | application of broiler (gallus gallus domesticus) litter to grasslands can increase ammonium (nh4-n) and dissolved reactive phosphorus (drp) concentrations in surface runoff, but it is not known for how long after a broiler litter application that these concentrations remain elevated. this long-term study was conducted to measure nh4-n and drp in surface runoff from grasslands fertilized with broiler litter. six 0.75-ha, fescue (festuca arundinacea schreb.-)bermudagrass [cynodon dactylon (l.) pe ... | 2001 | 11577887 |
| phosphorus losses from grasslands fertilized with broiler litter: epic simulations. | broiler litter, a mixture of poultry excreta and bedding material, is commonly used to fertilize grasslands in the southeastern usa. previous work has shown that under certain situations, application of broiler (gallus gallus domesticus) litter to grasslands may lead to elevated levels of phosphorus (p) in surface runoff. the epic simulation model may be a useful tool to identify those situations. this work was conducted to evaluate epic's ability to simulate event and annual runoff volume and l ... | 2001 | 11577888 |
| impact of heating-degree-day accumulation during bermudagrass hay storage on nutrient utilization by lambs. | spontaneous heating in stored alfalfa (medicago sativa) has reduced forage quality and dm and n digestibility through microbial respiration and maillard polymer formation. the impact of heating-degree-day (hdd) accumulation in stored bermudagrass (cynodon dactylon [l.] pers.) was evaluated for its effect on nutrient utilization by lambs. twenty rambouillet wether lambs (53.1 +/- 0.74 kg) were used in a completely randomized total collection experiment. the hays selected for this study had previo ... | 2001 | 11721850 |
| effects of calendar date and summer management on the in situ dry matter and fiber degradation of stockpiled forage from bermudagrass pastures. | limited information is available that describes the disappearance kinetics of bermudagrass (cynodon dactylon l. pers.) during fall and early winter. five ruminally cannulated, crossbred steers (387 +/- 18.3 kg) were used to determine the effects of calendar date and previous summer management on the in situ degradation kinetics of dm and ndf for forage clipped from stockpiled 'greenfield' bermudagrass pastures. forage was stockpiled at two sites following summer hay or pasture management, and sa ... | 2001 | 11811472 |
