The objective of this paper is to describe clinical behavior, histopathologic features, and immunohistochemical staining of two‐related horses with intraocular teratoid medulloepithelioma. Two‐related Quarter Horses with similar intraocular masses presented to the UF‐CVM Comparative Ophthalmology Service for evaluation and treatment. The first horse, a 3‐year‐old gelding, had glaucoma and a cyst‐like mass in the anterior chamber. Enucleation was performed. Histopathology revealed a teratoid medulloepithelioma. The tumor was considered to be completely excised. Fifteen months later, the gelding presented with swelling of the enucleated orbit and local lymph nodes with deformation of the skull. Cytology revealed neuroectodermal neoplastic cells. Necropsy confirmed tumor metastasis. Six weeks later, a 9‐year‐old mare, a full sibling to the gelding, presented for examination. An infiltrative mass of the iris and ciliary body was found that extended into the anterior, posterior, and vitreal chambers. Uveitis was present, but secondary glaucoma was not noted. Enucleation was performed and the histopathologic diagnosis was also teratoid medulloepithelioma. The mare has had no recurrence to date, 2 years following enucleation. Metastasis of intraocular teratoid medulloepithelioma is possible. Staging is recommended in cases where the diagnosis of teratoid medulloepithelioma is confirmed. Surveillance of full siblings is recommended until more information regarding etiology is known. 相似文献

A retrospective study of 43 cases of temporohyoid osteoarthropathy was performed to evaluate the epidemiological features and a possible association with crib‐biting. Data collected from records included case details, what diagnostics were utilised, whether medical or surgical treatment was administered, and outcome. Owners were contacted via telephone and asked whether the horse had displayed crib‐biting behaviour. Forty‐three horses were diagnosed with neurological disease associated with temporohyoid osteoarthropathy, 62.8% of which were Quarter Horse‐types. Median age at presentation was 10 years and median duration of neurological signs prior to presentation was 3 days. Skull radiographs and guttural pouch endoscopy were used to definitively diagnose temporohyoid osteoarthropathy in 72% of the cases. Of 43 horses, 21 received medical treatment and 15 surgical treatment, with an overall survival rate of 55.8%. Crib‐biting was observed in 31.3% of cases and there was a significant association between being afflicted with THO and likelihood of possessing the behaviour. Horses with neurological disease associated with THO were 8 times more likely to be crib‐biters compared to the general population. 相似文献

This report involves 6 cases in which medical records and post mortem findings were reviewed leading to the diagnosis of massive pulmonary thromboembolism (MPTE). All horses were mature and MPTE has not been recognised previously as a sequel to generalised systemic illness in mature horses. The clinical data and pathological findings of the cases are reported and the authors conclude that MPTE is an uncommon but important complication of medical and surgical disorders in mature horses. In 3 of the cases, the condition was nonfatal suggesting that some horses having developed PTE survive and the condition may not be recognised in such cases. The incidence of the condition might be higher than supposed. 相似文献

We report the spontaneous formation of uniformly distributed arrays of "tips" (tall conical hillocks) upon oxidation of palladium (Pd) thin films. The formation of the palladium oxide tips depended on the thickness and granularity of the Pd film and on annealing and oxidation conditions. As the Pd film thickness increased from 40 to 200 nanometers, the average height of the tips increased from 0.5 to 1.2 micrometers, their height distribution became broader, and their density decreased from 55 x 10(6) to 12 x 10(6) per square centimeter. Enhanced photoelectron emission from locations corresponding to the tips suggests their possible use in field emission applications. 相似文献

This paper deals with problems concerning measurements of rainfall acidity and interpretation in terms of possible effects on the soil-plant system. The theory of acidity relationships of the carbon dioxide-bicarbonate equilibria and its effect on rainfall acidity measurements is given. The relationship of a cation-anion balance model of acidity in rainfall to plant nutrient uptake processes is discussed, along with the relationship of this model to a rainfall acidity model previously proposed in the literature. These considerations lead to the conclusion that average H+ concentration calculated from pH measurements is not a satisfactory method of determining H+ loading from rainfall if the rain is not consistently acid. Calculating loading from H+ minus HCO3 ? , strong acid anions minus basic cations, or net titratable acidity is suggested. The flux of H+ ions in soil systems due to plant uptake processes and sulfur and nitrogen cycling is considered. H+ is produced by oxidation of reduced sulfur and nitrogen compounds mineralized during decomposition of organic matter. Plant uptake processes may result in production of either H+ or OH? ions. Fluxes of H+ from these processes are much greater than rainfall H+ inputs, complicating measurement and interpretation of rainfall effects. The soil acidifying potential due to the oxidation of the NH4 + rainfall is examined, with the conclusion that acidity from this source is of a similar magnitude to direct H+ inputs common in rainfall. 相似文献

Seven field trials with Zn were carried out in 1965, 1966, and 1967 to determine source and placement effects of ZnEDTA (Zn ethylene-diaminetetraacetate) and ZnSO4 on the yield and composition of potatoes grown in the San Luis Valley of Colorado. Application of Zn increased the yield of U.S. No. 1 potatoes from 16 to 95% on soils having less than 4.8 ppm of 0.1NHCI-extractable Zn. No yield response was obtained on soils having greater than 5.5 ppm of extractable Zn. Uptake of Zn was greater from soil-applied ZnEDTA than from soilapplied ZnSO4. Banding ZnSO4 approximately 3 inches (7.6 cm) directly below the seed piece was more efficient than discing it or sidebanding it 5 inches (12.7 cm) to the side and 3 inches (7.6 cm) below the seed piece. Two foliar sprays of either ZnSO4 or ZnEDTA solutions (0.5%) were also effective in correcting Zn deficiency. Zinc content of the foliage was not a good indicator of the Zn nutrition of potato plants. 相似文献
