ABSTRACT.
An outbreak of pulmonary edema and emphysema with acute and chronic cases is reported in a farm in Uruguay. In a herd of 40 Hereford steers, 20 died. The deaths began four days after a change of paddock, from an old pasture of Avena sativa to a lush growing pasture of the same grass. Acutely affected animals showed severe dyspnea, sialorrhea, cough, and subcutaneous edema, and died within 72 hours. Chronically affected steers showed dyspnea, respiratory noises, weight loss, and intolerance to exercise. The deaths began four days after the change of paddock. Ten days after the first death, the steers were withdrawn from the pasture, but continued dying throughout the following 40 days. Twenty animals died and six were necropsied. Grossly, the lungs were diffusely armed and glistening, with reddish and crepitant cut surface, and presented alveolar septae sharply distended by edema and emphysema. There was subpleural emphysema with air blebs distributed across the pleural surface. Presence of Dictyocaulus viviparus was observed in three steers. In some animals, the trachea was diffusely reddish with presence of pink foam; in some others, there was bloody liquid in the tracheal lumen. Histologic examination showed severe diffuse alveolar and interstitial emphysema, hyaline membranes adhered to the alveolar wall, thickening of the interlobular septae with proliferation of type II pneumocytes, and moderate-to-severe multifocal histiocytic, neutrophilic and eosinophilic infiltrate. In the trachea, there was submucosal hemorrhage and moderate multifocal eosinophilic and lymphocytic infiltrate. The steers with chronic signs presented similar lung lesions, but multifocal pulmonary fibrosis and cardiac dilatation were also observed. The diagnosis of acute bovine pulmonary emphysema and edema (ABPE) was based on the occurrence of the disease after introduction of the herd in a lush green pasture, on the characteristic gross and histologic lesions, and on the absence of other toxic or infectious agents causing similar lesions. Cattle raisers should be alert to the risks of occurrence of this disease after the introduction of the herds into paddocks with green and lush pastures.

RESUMO.
Descreve-se um surto de edema e enfisema pulmonar com casos agudos e crônicos em bovinos em uma criação semi-intensiva no Uruguai. De um lote de 40 novilhos da raça Hereford morreram 20. As mortes começaram quatro dias após uma mudança de alimentação, de uma pastagem mais velha de Avena sativa, para uma pastagem recentemente plantada de aveia que estava em brotação. Os animais afetados apresentaram sinais clínicos agudos de dispneia, sialorreia, tosse e alguns desenvolveram edema subcutâneo, morrendo em até 72 horas. Outros novilhos mais cronicamente afetados apresentaram dispneia, ruídos respiratórios, perda de peso e intolerância ao exercício. As mortes começaram quatro dias após a mudança de pastagens. Dez dias após a primeira morte, os novilhos foram retirados do pasto, mas morreram ainda durante 40 dias mais. Ao total, morreram vinte animais e seis foram necropsiados. Nas necropsias dos animais mortos na fase aguda os pulmões estavam difusamente armados e brilhosos e ao corte de coloração avermelhada e crepitante, com os septos alveolares acentuadamente distendidos por edema e enfisema. Havia enfisema subpleural caracterizado por bolhas de ar distribuídas pela superfície pleural. Em três bovinos havia ainda presença de Dictyocaulus viviparus. Alguns animais apresentaram a traqueia difusamente avermelhada com espuma de coloração rósea ou liquido sanguinolento livre na luz traqueal. Histologicamente havia edema e enfisema alveolar e intersticial difuso severo, membranas hialinas espessas aderidas à parede alveolar, espessamento dos septos interlobulares com proliferação de pneumócitos tipo II e infiltrado inflamatório histiocítico, neutrofílico e eosinofílico multifocal moderado a severo. Na traqueia havia hemorragias na submucosa e infiltrado eosinofílico e linfocítico multifocal. Os novilhos com sinais crônicos apresentaram lesões pulmonares semelhantes, entretanto, foram observadas também, fibrose pulmonar multifocal e dilatação cardíaca. O diagnóstico de EEPAB baseou-se na ocorrência da doença após a introdução do rebanho em uma pastagem viçosa em brotação, nas características macroscópicas e histológicas e na ausência de outros agentes tóxicos ou infecciosos que causam lesões semelhantes. Se alerta para os riscos da ocorrência desta enfermidade, quando houver mudanças de pastagens. MenosABSTRACT.

ABSTRACT.
The bread making quality of wheat (Triticum aestivum L.) depends on the quality and quantity of the gluten proteins -glutenins and gliadins- which constitute 10 to 14% of the grain protein content. Various quantitative parameters, such as the total content of proteins of the flour, content of polymeric proteins present in the grain and the glutenin/gliadin ratio are related to baking quality. This work presents the characterization of high molecular weight glutenin subunits (HMW-GS) by sodium dodecyl sulphate (SDS) polyacrylamide gel electrophoresis (SDS-PAGE) of 22 Uruguayan cultivars and breeding lines. 14 HMW-GS subunits were observed corresponding to 10 allele combinations. On the other hand, it is proposed a simple method to group and quantify the main storage proteins of bread wheat by SE-HPLC (Size Exclusion High Performance Liquid Chromatography). The chromatograms obtained showed an excellent separation of the endosperm proteins in three main peaks corresponding to polymeric, monomeric and non gluten proteins, respectively. The integrated areas of the chromatograms as well as the presence of subunits of the cultivars were analyzed. The genotypes analyzed showed quantitative differences in the quantity of glutenin/gliadin solubles in SDS and in the proportion of polymeric and monomeric proteins. The cultivar INIA Gorrión of good baking quality having the alleles Glu-D1 5+10 showed a lower percentage of SDS-soluble polymeric proteins and higher insoluble polymeric proteins than the experimental line LE 2265, which has the alleles Glu-D1 2+12.

RESUMEN.
La calidad del trigo para pan (Triticum aestivum L.) depende de la calidad y cantidad de las proteínas del gluten ?gluteninas y gliadinas? las cuales constituyen 10 a 14% de las proteínas del grano. Varios parámetros cuantitativos, como el contenido total de proteínas de la harina, el contenido de proteínas poliméricas presentes en el grano y la proporción de gluteninas y gliadinas, están relacionados a la calidad panadera. En este trabajo se presenta la caracterización de las gluteninas de alto peso molecular (G-APM) en geles de poliacrilamida en SDS (SDS-PAGE) de 22 cultivares
y líneas de mejoramiento de Uruguay. Fueron observadas 14 subunidades de G-APM correspondientes a 10 combinaciones alélicas. Por otra parte, se propone un método sencillo para agrupar y cuantificar las principales proteínas de reserva de trigo mediante cromatografía líquida de exclusión por tamaño de alta resolución (SE-HPLC). Los cromatogramas obtenidos mostraron una excelente separación de las proteínas del endospermo en tres picos principales correspondientes a proteínas poliméricas, monoméricas y no gluten, respectivamente. El área de integración de los cromatogramas así como la presencia de subunidades de los cultivares fueron analizados. Los genotipos estudiados mostraron diferencias cuantitativas en el contenido de gluteninas/gliadinas solubles en SDS, en la proporción de proteínas poliméricas y monoméricas. El cultivar INIA Gorrión, de buena calidad panadera y que presenta el alelo Glu-D1 5+10, mostró menor porcentaje de proteínas poliméricas solubles en SDS y mayor porcentaje de proteínas poliméricas insolubles en comparación con la línea experimental LE 2265, que tiene el par Glu-D1 2+12.
