The activity of ten compounds isolated from Brazilian lichen over the release of hydrogen peroxide and nitric oxide was evaluated in the culture of peritoneal macrophage cells from mice. Salazinic, secalonic A and fumarprotocetraric acids were the compounds that induced the greatest release of H2O2, whereas 12R-usnic and diffractaic acids induced the release of NO. These results indicate that lichen products have potential immunological modulating activities. 相似文献

Stimulation of early flowering is required to shorten breeding cycles of eastern cottonwood (Populus deltoides Bartr. ex Marsh. var. deltoides), a commercially important and fast-growing hardwood species. A series of experiments was conducted to evaluate the influence of various treatments on flowering in rooted cuttings from mature and juvenile trees. A combined treatment of water stress, root pruning and paclobutrazol was applied to 3-month-old rooted cuttings from mature trees. These cuttings had been subjected to root restriction and long days. All treated plants flowered, whereas no untreated plants formed flower buds. One-year-old rooted cuttings from juvenile trees did not flower when treated with either paclobutrazol, paclobutrazol plus water stress, paclobutrazol plus root pruning, or paclobutrazol plus girdling. This was true both under continuous or periodic growth. Assessment of the lack of flowering in juvenile trees may require an integrated approach that investigates environmental or physiological stimuli, assimilate shift, gibberellic acid type and concentration, and flowering-time gene activity in the new shoots of mature and juvenile cottonwood trees. 相似文献

Tree planting for poverty reduction in less-favoured areas of the Ethiopian highlands 总被引:1,自引:0,他引:1
This paper assesses the potential impact of planting of eucalypt trees as a strategy to reduce poverty in a less-favoured
area of the highlands of Ethiopia. Results from simulations with a bio-economic model for a less-favoured case study area
in the highlands are combined with survey data at community, household and plot level to assess how general the results of
the bio-economic model are. Application of the bio-economic model shows clearly that land degradation, population growth,
stagnant technology and drought threaten food security. Household welfare and land quality are deteriorating rapidly in the
area and interventions are urgently needed to avoid human disaster. Planting of eucalypts on land unsuitable for crop production
may substantially increase household incomes if market outlets for trees can be found. Tree planting will not have severe
negative effects on food production or land conservation. A policy combining promotion of tree planting and conservation of
cropland may achieve win-win benefits in terms of increased household incomes as well as more sustainable land-use. Analysis
of survey data from the Amhara Region of Ethiopia reveals that there is a large area of land that is unsuitable for crop production
located close to all-weather roads in the less-favoured areas of the region. Few trees have been planted on this type of land
up to now. The past policy seems to have discouraged tree planting except on homestead plots that are more suitable for food
crops.
This paper reports part of the IFPRI/ILRI project ‘Policies for Sustainable Land Management in the East African Highlands’.
These two agencies have provided funds and logistical support for the work. The Norwegian Ministry of Foreign Affairs has
provided funds for this research in the Amhara Region in Ethiopia. The authors also draw on earlier work funded by Research
Council of Norway. Any correspondence should be directed to the first author. 相似文献

From the leaves of Eucalyptus consideniana and E. viminalis, known hydrolysable tannins, galloyl esters and ellagitannins, were isolated. Flavonol glycosides were also isolated from the leaves of E. consideniana. The spectral data of the dimeric ellagitannin, oenothein B (1), are reported. 相似文献

With the recent introduction of a 0.25T rotating MRI system, clinical evaluation of the equine stifle joint is now possible in the average equine athlete. A recent publication described common abnormalities of horses with stifle lameness detected with a low‐field MRI system; however, postmortem corroboration of the lesions detected was not possible. Therefore, our objective was to compare postmortem findings with low‐field MRI findings in equine cadaver stifle joints. Ten fresh cadaver stifle joints from horses without clinical signs of stifle disease were evaluated using low‐field MRI, gross dissection, and histopathology. In eight stifles, either the lateral or medial cranial meniscotibial ligament had an irregular shape, fiber separation, or moderate abnormal signal intensity (SI) on all sequences. In five stifles, the medial femoral condyle had articular cartilage fibrillation with or without an osteochondral defect over the weight bearing surface of the medial femoral condyle. All stifles had abnormal SI on all sequences within the patellar ligaments that corresponded with adipose tissue infiltrating between the collagen bundles. Other abnormalities identified included articular cartilage fibrillation of the tibial condyles in three stifles, and articular cartilage fibrillation with chondral defects in the patella in three stifles. All abnormalities detected with low‐field MRI were corroborated by gross dissection. Findings from the current study supported the use of low‐field MRI for detection of stifle joint lesions in horses and demonstrated that some stifle joint pathologies may be subclinical in horses. 相似文献
