Hypoxia was induced by decreasing the inspired fiO2 to 0.06-0.08. Animals were resuscitated with different fO2 and subdivided into 4 groups： group 1, 2, 3 and 4 received 18%, 21%, 40% and 100% O2 respectively. Macroscopic examination was carried out to evidence possible pathological features. Tissue sample were obtained from both kidneys. Four or fve micron paraffn sections were stained with H-E and PAS stain and examined under an optical microscope.RESULTS： Pathological changes, mainly affecting tubular cells, were observed in the vast majority of kidneys of asphyxiated piglets. The most frequent tubular changes were： tubular casts （95%）, tubulardilatation （87.5%）, tubular vacuolization （70%）, tubular eosinophilia （52.5%）, sloughing （50%）, fragmentation of the brush border （50%）, oedema （32.5%）, apoptosis （15%） and glomerular changes （meningeal cell pro-liferation, capsular adhesion between the flocculus and Bowman’s capsule, glomerulosclerosis and fbrous or cellular crescents associated with collapse of the glomerular tuft）. Statistical analysis was carried out on changes observed when the animals were allocated in the 4 groups （χ2-test 0.05）. The statistical analysis showed no evidence of differences regarding kidney lesions among the animals groups.CONCLUSION： Our data show that renal pathology in newborn piglets is characterized by interindividual variability to hypoxia and is not associated with oxygenGerosa C et al . Individual susceptibility in renal asphyxiaconcentration.展开更多

LILA has a closed-loop water delivery system and consists of four 0.08 square kilometer （-8 ha） macrocosms, created to be replicates of one another and of the Everglades landscape. Built in 2003, LILA＇s purpose is to provide scientists with an opportunity to design and implement research concerning Everglades restoration techniques in an accessible, controlled and replicated Everglades environment. Key Everglades habitats were sculpted within LILA： tree islands, ridges, sloughs and alligator holes. Water levels and flows in each macrocosm are controlled independently, so that researchers can study the effects of hydrology on Everglades landscape and ecology. Studies have focused upon measuring survival and growth of native trees planted on the tree islands; measuring surface water and ground water movement and chemistry; studying wading bird feeding and the movement of prey species （crayfish）; and measuring erosion and accretion on tree islands and ridges. We developed a Geographic Information System （GIS） data set to identify, characterize, and spatially reference the features of LILA and document research activities. This development included mapping the boundaries of the landscape features, creating a theoretical Digital Elevation Model （DEM） and describing the research projects being carried out. The creation of this GIS data set enhances the ability to schedule and coordinate research, assist scientists in the visualization and spatial representation of their research, and provide a resource for the storage, analysis and synthesis of valuable scientific information.展开更多
