A 15-year-old Paso Fino gelding was evaluated because of acute renal failure following an episode of exertional rhabdomyolysis. The horse was azotemic and treated conservatively at another referral practice with no improvement in the azotemia. With conservative treatment and intermittent peritoneal dialysis, the horse had minimal improvement. Continuous-flow peritoneal dialysis (CFPD) was instituted on day 7 and continued for 3 consecutive days. Dramatic changes in the horse's attitude and serum creatinine concentration were detected within the first 24 hours of CFPD treatment. The horse remained hospitalized for 23 days; within 3 months of discharge, serum BUN and creatinine concentrations had returned to within the reference ranges and the horse had resumed normal activity. In adult horses, it appears that CFPD can be used to successfully treat acute renal failure that is refractory to conventional treatments. 相似文献

Relaxin, a 6-kDa polypeptide hormone, is excreted in the urine during pregnancy in several mammalian species. A recent study showed that detection of urinary relaxin using a bench-top serum assay (Witness relaxin kit, Synbiotics Corp., San Diego, California 92127, USA) can be diagnostic for pregnancy in domestic cats (Felis silvestris catus), but it is unknown whether the bench-top kit is applicable with urine across felid species. Our objectives were to 1) examine modifications in urine processing to improve kit reliability in pregnant cats, 2) evaluate the impact of concentrating urine via filtration on relaxin detection, 3) assess the effect of sample freezing on relaxin concentrations, and 4) begin quantifying urinary relaxin levels in nondomestic felids. Urine and serum were collected from domestic cats and nondomestic cat species (Pallas' cat, Otocolobus manul; sand cat, Felis margarita; cheetah, Acinonyx jubatus; and lion, Panthera leo) at several times after breeding. Urine samples, subjected to various processing methods, were tested using the bench-top kit, and relaxin levels were later quantified via radioimmunoassay. For domestic cat urine samples, filtration and addition of protein/phosphate buffer improved the consistency of the relaxin kit for early pregnancy diagnosis. Urine freezing caused a slight (approximately 13%) but significant decrease in relaxin concentrations, but frozen-thawed samples still tested positive with the bench-top kit. In nondomestic felids, urinary relaxin immunoreactivity during pregnancy was similar to or higher than that of pregnant domestic cats, suggesting that relaxin is a reliable cross-species marker of pregnancy. Urinary relaxin was detectable using the bench-top kit in pregnant Pallas' cats, but urine samples from other species tested negative, regardless of processing methods. Findings suggest that measurement of urinary relaxin is a promising approach for noninvasive pregnancy diagnosis in exotic felids, but further assessment of urinary relaxin profiles among cat species and modification of the bench-top relaxin kit are warranted to improve cross-species utility. 相似文献

Species distribution models (SDMs) often use elevation as a surrogate for temperature or utilise elevation sensitive interpolations
from weather stations. These methods may be unsuitable at the landscape scale, especially where there are sparse weather stations,
dramatic variations in exposure or low elevational ranges. The goal of this study was to determine whether radiation, moisture
or a novel estimate of exposure could improve temperature estimates and SDMs for vegetation on the Illawarra Escarpment, near
Sydney, Australia. Forty temperature sensors were placed on the soil surface of an approximately 12,000 ha study site between
November 2004 and August 2006. Linear regression was used to determine the relationship with environmental factors. Elevation
was correlated more with moderate temperatures (winter maximums, summer minimums, spring and autumn averages) than extreme
temperatures (summer maximums, winter minimums). The correlation (r
2) between temperature and environmental factors was improved by up to 0.38 by incorporating exposure, moisture and radiation
in the regressions. Summer maximums and winter minimums were predominately determined by exposure to the NW and coastal influences
respectively, while exposure to the NE and SW was important during other seasons. These directions correspond with the winds
that are most influential in the study area. The improved temperature estimates were used in Generalised Additive Models for
37 plant species. The deviance explained by most models was increased relative to elevation, especially for moist rainforest
species. It was concluded that improving the accuracy of seasonal temperature estimates could improve our ability to explain
the patchy distribution of many species.

A 9-year-old mare presented with a 2-week history of partial anorexia, multiple swellings in the area of the throatlatch, and purulent nasal discharge. On initial presentation, the horse had submandibular and retropharyngeal lymphadenopathy, mild ventral edema, and weight loss. Thoracic radiographs revealed a pulmonary interstitial pattern. Necropsy revealed enlarged lymph nodes throughout the body. The lung parenchyma contained multiple random, well-circumscribed nodules, which, on cut section, were pale, tan colored, and very firm with a distinct line of demarcation from the surrounding normal parenchyma. The subendocardium of the left ventricle, left atrium, and, multifocally, the right ventricle contained white, gritty areas of mineralization. There was marked subintimal mineralization of the aorta and pulmonary artery. Histopathology of the lymph nodes revealed effacement of the parenchyma by a neoplasm composed of large numbers of small mature lymphocytes, fewer large lymphocytes, and scattered moderate numbers of histiocytes. Immunohistochemistry tests for CD3, CD79a, and CD20, confirmed the lymphoma was T-cell-rich B-cell lymphoma. The lungs contained marked interstitial fibrosis with alveolar histiocytosis. Polymerase chain reaction test results of lymph node and lungs were positive for equine herpesvirus-5 (EHV-5), a gammaherpesvirus. Gammaherpesvirus infection has been associated with lymphoma and pulmonary fibrosis in other species. This report describes the association between EHV-5 and both pulmonary fibrosis and lymphoma. 相似文献

A 15-month-old male Maine Coon Cat presented with persistent auricular discharge and progressive head tilt, ataxia, and loss of blink on the right side. Using computed tomography a hyperattenuating, contrast-enhancing material within a thickened right tympanic bulla and contrast enhancement of the adjacent cerebellum were identified. Marked suppurative inflammation was identified on cerebrospinal fluid analysis with no growth on bacterial culture. Ventral bulla osteotomy was performed to remove a soft tissue mass, and an inflammatory polyp with chronic severe suppurative inflammation was confirmed using histology. Staphylococcus auricularis was grown on aerobic culture and Fusobacterium necrophorum and Peptostreptococcus anaerobius were grown on anaerobic culture. The cat was treated for 10 weeks with amoxicillin/clavulinic acid and metronidazole. Dramatic improvement in body weight, appetite, energy level, balance, and resolution of right-sided facial paralysis were noted, but the cat retained a head tilt. 相似文献

Assignment of the denso Dwarfing Gene to the Long Arm of Chromosome 3(3H) of Barley by Use of RFLP Markers 总被引:1,自引:2,他引:1
RFLP analysis of 105 doubled haploid lines from a cross between the barley varieties ‘Magnum’ and ‘Goldmarker’ located the denso dwarfing gene on the long arm of chromosome 3(3H), approximately 8 cM distal to the RFLP locus Xpsrl70. Lines with the denso gene showed a distinctive prostrate juvenile growth habit and tended to have later ear emergence times and lower plant grain weights, ear grain weights and 50 grain weights. 相似文献

Summary In the course of experiments performed to obtain haploid wheat plants in which 2,4-dichlorophenoxyacetic acid (2,4-D) was applied to developing spikes, it was found that three cultivars showed a different ability to produce polyembryos (Thatcher 20.19%, Chris 7.06%, Dollar 0%). This behaviour was related to their capacity to form somatic embryos. Diploid immature embryos cultured in vitro after 2,4-D treatment, gave a higher frequency of embryogenic callus in Thatcher and Chris than in Dollar. As the common factor in both experiments was the 2,4-D treatment we propose that the three cultivars showed a differential sensitivity to 2,4-D. 相似文献

This paper describes the application of an economic incentive program to achieve water quality objectives by motivating improvements in farm-level water management practices. The program includes farm-specific water allotments, tiered water pricing, and low-interest loans for purchasing irrigation equipment. The implementation of this program in a California water district has resulted in significant reductions in irrigation deliveries and drain water volume. Since the program was implemented, average irrigation depths have declined by 25% on cotton fields, 9% on tomatoes, 10% on cantaloupes, 30% on seed alfalfa, and 29% on grain fields. The average volume of drain water collected each year in subsurface drainage systems has declined from 4.8 million m3 during 1986 through 1989 to 2.6 million m3 during 1990 through 1993. These results confirm that economic incentives can be effective in generating improvements in water quality. 相似文献
