Abstract: Pt Es En

A cardiomiopatia hipertrófica (CMH) é uma forma de doença do músculo cardíaco de causa genética, caracterizada pela hipertrofia das paredes ventriculares. O diagnóstico requer detecção por métodos de imagem (Ecocardiograma ou Ressonância Magnética Cardíaca) de qualquer segmento da parede do ventrículo esquerdo com espessura > 15 mm, sem outra causa provável. A análise genética permite identificar mutações de genes codificantes de diferentes estruturas do sarcômero responsáveis pelo desenvolvimento da CMH em cerca de 60% dos casos, permitindo o rastreio de familiares e aconselhamento genético, como parte importante do manejo dos pacientes e familiares. Vários conceitos sobre a CMH foram recentemente revistos, incluindo sua prevalência de 1 em 250 indivíduos, não sendo, portanto, uma doença rara, mas subdiagnosticada. A vasta maioria dos pacientes é assintomática. Naqueles sintomáticos, a obstrução do trato de saída do ventrículo esquerdo (OTSVE) é o principal distúrbio responsável pelos sintomas, devendo-se investigar a sua presença em todos os casos. Naqueles em que o ecocardiograma em repouso ou com Manobra de Valsalva não detecta gradiente intraventricular significativo (> 30 mmHg), devem ser submetidos à ecocardiografia com esforço físico para detecção da OTSVE.   Pacientes com sintomas limitantes e grave OTSVE, refratários ao uso de betabloqueadores e verapamil, devem receber terapias de redução septal ou uso de novas drogas inibidoras da miosina cardíaca. Por fim, os pacientes adequadamente identificados com risco aumentado de morta súbita podem receber medida profilática com implante de cardiodesfibrilador implantável (CDI).

La miocardiopatía hipertrófica (MCH) es una forma de enfermedad cardíaca de origen genético, caracterizada por el engrosamiento de las paredes ventriculares. El diagnóstico requiere la detección mediante métodos de imagen (Ecocardiograma o Resonancia Magnética Cardíaca) que muestren algún segmento de la pared ventricular izquierda con un grosor > 15 mm, sin otra causa probable. El análisis genético permite identificar mutaciones en genes que codifican diferentes estructuras del sarcómero responsables del desarrollo de la MCH en aproximadamente el 60% de los casos, lo que permite el tamizaje de familiares y el asesoramiento genético, como parte importante del manejo de pacientes y familiares. Varios conceptos sobre la MCH han sido revisados recientemente, incluida su prevalencia de 1 entre 250 individuos, por lo tanto, no es una enfermedad rara, sino subdiagnosticada. La gran mayoría de los pacientes son asintomáticos. En los casos sintomáticos, la obstrucción del tracto de salida ventricular izquierdo (TSVI) es el trastorno principal responsable de los síntomas, y su presencia debe investigarse en todos los casos. En aquellos en los que el ecocardiograma en reposo o la maniobra de Valsalva no detecta un gradiente intraventricular significativo (> 30 mmHg), deben someterse a ecocardiografía de esfuerzo para detectar la obstrucción del TSVI. Los pacientes con síntomas limitantes y obstrucción grave del TSVI, refractarios al uso de betabloqueantes y verapamilo, deben recibir terapias de reducción septal o usar nuevos medicamentos inhibidores de la miosina cardíaca. Finalmente, los pacientes adecuadamente identificados con un riesgo aumentado de muerte súbita pueden recibir medidas profilácticas con el implante de un cardioversor-desfibrilador implantable (CDI).

Hypertrophic cardiomyopathy (HCM) is a form of genetically caused heart muscle disease, characterized by the thickening of the ventricular walls. Diagnosis requires detection through imaging methods (Echocardiogram or Cardiac Magnetic Resonance) showing any segment of the left ventricular wall with a thickness > 15 mm, without any other probable cause. Genetic analysis allows the identification of mutations in genes encoding different structures of the sarcomere responsible for the development of HCM in about 60% of cases, enabling screening of family members and genetic counseling, as an important part of patient and family management. Several concepts about HCM have recently been reviewed, including its prevalence of 1 in 250 individuals, hence not a rare but rather underdiagnosed disease. The vast majority of patients are asymptomatic. In symptomatic cases, obstruction of the left ventricular outflow tract (LVOT) is the primary disorder responsible for symptoms, and its presence should be investigated in all cases. In those where resting echocardiogram or Valsalva maneuver does not detect significant intraventricular gradient (> 30 mmHg), they should undergo stress echocardiography to detect LVOT obstruction. Patients with limiting symptoms and severe LVOT obstruction, refractory to beta-blockers and verapamil, should receive septal reduction therapies or use new drugs inhibiting cardiac myosin. Finally, appropriately identified patients at increased risk of sudden death may receive prophylactic measure with implantable cardioverter-defibrillator (ICD) implantation.

ABSTRACT Objective: To define a reference chart comparing pressure drop vs. flow generated by a set of arterial cannulae currently utilized in cardiopulmonary bypass conditions in pediatric surgery. Methods: Cannulae from two manufacturers were selected considering their design and outer and inner diameters. Cannula performance was evaluated in terms of pressure drop vs. flow during simulated cardiopulmonary bypass conditions. The experimental circuits consisted of a Jostra HL-20 roller pump, a Quadrox-i pediatric oxygenator (Maquet Cardiopulmonary AG, Rastatt, Germany), and a custom pediatric tubing set. The circuit was primed with lactated Ringer’s solution only (first condition) and with human packed red blood cells added (second condition) to achieve a hematocrit of 30%. Cannula sizes 8 to 16 Fr were inserted into the cardiopulmonary bypass circuit with a “Y” connector. The flow was adjusted in 100 ml/min increments within typical flow ranges for each cannula. Pre-cannula and post-cannula pressures were measured to calculate the pressure drop. Results: Utilizing a pressure drop limit of 100 mmHg, our results suggest a recommended flow limit of 500, 900, 1400, 2600, and 3100 mL/min for Braile arterial cannulae sizes 8, 10, 12, 14, and 16 Fr, respectively. For Medtronic DLP arterial cannulae sizes 8, 10, 12, 14, and 16 Fr, the recommended flow limit is 600, 1100, 1700, 2700, and 3300 mL/min, respectively. Conclusion: This study reinforces discrepancies in pressure drop between cannulae of the same diameter supplied by different manufacturers and the importance of independent translational research to evaluate components’ performance.

Abstract: En Pt

The description of the new species for Brazil, Cheilolejeunea savannae L.P. Macedo, Ilk.-Borg. amp; C.J. Bastos, raised the need to review many specimens previously identified as Cheilolejeunea intertexta (Lindenb.) Steph., aiming to refine the concept of this species and its real distribution in Brazil. The present study also resulted in the reinstatement of Cheilolejeunea compacta (Steph.) M.E. Reiner previously considered synonymous with C. intertexta, as a distinct taxon. It also showed that C. savannae has a wider distribution in Brazil and especially in the State of Bahia, compared to C. intertexta and C. compacta. Descriptions and a key to the separation of the three species recognized here are presented.

Abstract Objective: To assess the predictive value of selected growth phenotypes for neonatal morbidity and mortality in preterm infants < 30 weeks and to compare them with INTERGROWTH-21st (IG21). Methods: Retrospective analysis of data from the Brazilian Neonatal Research Network (BNRN) database for very low birth weight (VLBW) at 20 public tertiary-care university hospitals. Outcome: the composite neonatal morbidity and mortality (CNMM) consisted of in-hospital death, oxygen use at 36 weeks, intraventricular hemorrhage grade 3 or 4, and Bell stage 2 or 3 necrotizing enterocolitis. Selected growth phenotypes: small-for-gestational-age (SGA) defined as being < 3rd (SGA3) or 10th (SGA10) percentiles of BW, and large-for-gestational-age (LGA) as being > 97th percentile of BW. Stunting as being < 3rd percentile of the length and wasting as being < 3rd percentile of BMI. Single and multiple log-binomial regression models were fitted to estimate the relative risks of CNMM, comparing them to IG21. Results: 4,072 infants were included. The adjusted relative risks of CNMM associated with selected growth phenotypes were (BNRN/IG21): 1.45 (0.92–2.31)/1.60 (1.27–2.02) for SGA; 0.90 (0.55–1.47)/1.05 (0.55–1.99) for LGA; 1.65 (1.08–2.51)/1.58 (1.28–1.96) for stunting; and 1.48 (1.02–2.17) for wasting. Agreement between the two references was variable. The growth phenotypes had good specificity (>95%) and positive predictive value (70-90%), with poor sensitivity and low negative predictive value. Conclusion: The BNRN phenotypes at birth differed markedly from the IG21 standard and showed poor accuracy in predicting adverse neonatal outcomes.

RESUMO: A variabilidade genética é a base para o progresso genético em café. Este estudo teve como objetivo, avaliar o potencial de caracteres morfoagronômicos e anatômicos foliares em estudos de variabilidade genética entre cultivares de Coffea canephora. Dez genótipos foram distribuídos em um experimento seguindo delineamento em blocos ao acaso com três repetições. Foram detectadas diferenças significativas entre os genótipos pelo teste F (P < 0,05) para 13 dos 15 caracteres avaliados. Esses resultados evidenciaram a heterogeneidade entre as cultivares estudadas, o que é essencial para a composição da base genética e avanço dos programas de melhoramento. O teste de Scott e Knott detectou as diferenças entre os genótipos, separando-os em quatro grupos. Os caracteres anatômicos foliares apresentaram as maiores variações. Cinco, dentre os sete caracteres anatômicos foliares, apresentaram estimativas de herdabilidade superiores a 80% com destaque para a densidade estomática (95,69%) e comprimento do poro estomático (92,72%). Correlações positivas foram observadas entre caracteres morfoagronômicos e anatômicos foliares. A análise de agrupamento, considerando a distância de Mahalanobis como medida de dissimilaridade (D²), apontou a distinção de dois grupos de genótipos. A inclusão de caracteres anatômicos foliares na caracterização de genótipos de C. canephora pode auxiliar os melhoristas de plantas na melhor discriminação entre genótipos e maior segurança na seleção de clones para geração de novas cultivares.

ABSTRACT: Genetic variability is the basis for coffee genetic breeding. This study evaluated the potential of leaf anatomy and morpho-agronomic traits in studies of genetic variability in C. canephoracultivars. Ten genotypes were distributed in randomized block designs with three replicates. Significant differences among genotypes were detected by F-test (P < 0.05) for 13 of 15 evaluated traits. These results evidenced the heterogeneity of the studied cultivars, which is essential in composition of genetic basis in breeding programs. The Scott-Knott test detected variability among genotypes, grouped into up to four mean groups. Leaf anatomy traits presented the largest variations. Five out of seven leaf anatomy traits presented heritability higher than 80%, with emphasis on stomatal density (95.69%) and stomatal pore length (92.72%). Positive correlations were observed among morpho-agronomic and anatomic traits. Cluster analysis used the Mahalanobis general distance (D2) as a measure of genetic dissimilarity and divided the genotypes into two distinct groups. The inclusion of leaf anatomic traits to characterize C. canephoragenotypes may assist plant breeders with better genetic discrimination and with greater security in plant selection when composing cultivars.

Abstract Oral candidiasis is a common fungal infection that affects the oral mucosa, and happens when Candida albicans interacts with bacteria in the oral microbiota, such as Streptococcus mutans, causing severe early childhood caries. C. albicans and S. mutans mixed biofilms are challenging to treat with conventional antimicrobial therapies, thus, new anti-infective drugs are required. Objective This study aimed to test a drug delivery system based on chitosan microparticles loaded with geranium and lemongrass essential oils to inhibit C. albicans and S. mutans mixed biofilms. Methodology Chitosan microparticles loaded with essential oils (CM-EOs) were obtained by spray-drying. Susceptibility of planktonic were performed according CLSI at 4 to 2,048 µg/mL. Mixed biofilms were incubated at 37ºC for 48 h and exposed to CM-EOs at 256 to 4,096 µg/mL. The antimicrobial effect was evaluated using the MTT assay, with biofilm architectural changes analyzed by scanning electron microscopy. RAW 264.7 cell was used to evaluate compound cytotoxicity. Results CM-EOs had better planktonic activity against C. albicans than S. mutans. All samples reduced the metabolic activity of mixed C. albicans and S. mutans biofilms, with encapsulated oils showing better activity than raw chitosan or oils. The microparticles reduced the biofilm on the slides. The essential oils showed cytotoxic effects against RAW 264.7 cells, but encapsulation into chitosan microparticles decreased their toxicity. Conclusion This study demonstrates that chitosan loaded with essential oils may provide an alternative method for treating diseases caused by C. albicans and S. mutans mixed biofilm, such as dental caries.

ABSTRACT The present survey of leaf-blade trichomes of Mendoncia used SEM and light microscopy to investigate the diversity of trichome types in Neotropical and Paleotropical species of the genus. The eglandular trichomes are filiform, uniseriate, with asymmetric epidermal cells arranged radially around the trichome, these epidermal cells may be short or elongated, oriented in two groups. These cells, when elongated, are covered with epicuticular wax, forming smooth thick plates. African species have dendritic but not stellate trichomes. Character states such as number and length of basal cells were shown to overlap within the same species and therefore their use in isolation is not recommended for subgeneric classification of Mendoncia. Neotropical Mendoncia trichomes with well-developed epidermal cells arranged radially around the trichome appear to be unique to this group, without parallel in other plant families. leafblade leaf blade genus filiform uniseriate elongated groups wax plates welldeveloped well developed group families

RESUMO Os veículos aéreos não tripulados (VANTs), também conhecidos como drones, estão sendo cada vez mais utilizados em diversas demandas e aplicações, principalmente em mapeamento. Apesar da agilidade e praticidade fornecidas por essa tecnologia, os softwares de processamento de imagens existentes no mercado, possuem um custo muito elevado de forma a não atender as demandas do ensino/pesquisa principalmente das universidades públicas brasileiras. O objetivo desse estudo é avaliar a acurácia posicional dos produtos resultantes de processamento digital de imagens de VANTs a partir de um software comercial (Agisoft Metashape) e um outro de código aberto (Opendronemap). O resultado da acurácia planimétrica do ortofotomosaico decorrente dos dois programas não foi aceitável segundo as tolerâncias definidas no documento de padronização de acurácia planimétrica e altimétrica para dados digitais geoespaciais, estabelecido pela ASPRS (American Society for Photogrammetry and Remote Sensing). Somente a acurácia altimétrica correspondente ao MDE produzido pelo Opendronemap foi satisfatória.

ABSTRACT Unmanned aerial vehicles (UAVs), also known as drones, are being increasingly applied in different demands and applications, mainly in mapping. Despite the agility and practicality provided by this technology, the image processing software programs currently available on the market are costly and cannot meet teaching/research demands, especially in Brazilian public universities. In this context, this study aimed to evaluate the positional accuracy of products resulting from the digital processing of UAV images using commercial software (Agisoft Metashape) and open-source software (Opendronemap). The planimetric accuracy of the orthophoto mosaic resulting from the two software was not acceptable according to the tolerances defined in the standardization document for planimetric and altimetric accuracy for digital geospatial data, established by the ASPRS (American Society for Photogrammetry and Remote Sensing). Only the altimetric accuracy corresponding to the DEM produced by Opendronemap was satisfactory.

RESUMO Considerando a crescente demanda pela manga para atender ao mercado nacional e internacional e a competitividade entre os mercados produtores, o uso de novos produtos e técnicas de manejo que melhore o potencial produtivo nas áreas irrigadas do nordeste brasileiro pode ser uma importante ferramenta para sustentabilidade do cultivo da mesma. Neste contexto, o objetivo do presente estudo foi avaliar o efeito de doses e períodos de aplicação de cálcio proveniente das algas marinhas Lithothamnium via fertirrigação, em dois ciclos de produção da mangueira ‘Palmer’ no semiárido brasileiro. O experimento foi conduzido na fazenda Saúde, localizada no Projeto Senador Nilo Coelho N-09, na cidade de Petrolina, PE. O delineamento experimental foi em blocos casualizados, em esquema fatorial de 5 × 4 × 2, sendo cinco doses de Lithothamnium via fertirrigação (0; 5; 10; 15 e 20 L ha-1), quatro períodos de aplicação (30; 60; 90 e 120 dias após a floração) em dois ciclos de produção, com três blocos, totalizando 120 parcelas. As variáveis avaliadas foram: número de frutos comerciais e de manguitos por planta, peso médio dos frutos comerciais e de manguitos, e produção comercial de frutos. A dose de 12 L por planta de cálcio proveniente do Lithothamnium proporciona um incremento de 20% na produtividade da mangueira ‘Palmer’ no Vale do Submédio do São Francisco. A aplicação do cálcio proveniente do Lithothamnium deve ser realizada do início até 30 dias após a floração da mangueira ‘Palmer’, no Vale do Submédio São Francisco. O efeito da aplicação do cálcio proveniente das algas marinhas Lithothamnium sobre a produção da mangueira ‘Palmer’ varia em função das doses e dos ciclos produtivos.

ABSTRACT Considering the growing demand for mango to meet the national and international market and the competitiveness among the producing markets, the use of new products and management techniques that improve the potential production in the irrigated areas of the Brazilian northeast can be an important tool for the sustainability of its cultivation. In this context, the objective of the present study was to evaluate the effect of doses and periods of application of calcium from Lithothamnium seaweed via fertigation, in two production cycles of ‘Palmer’ mango in the Brazilian semiarid region. The experiment was conducted at the Saúde farm, located in the Projeto Senador Nilo Coelho N-09, in the city of Petrolina, PE, Brazil. The experimental design was randomized blocks, in a 5 × 4 × 2 factorial scheme, corresponding to five doses of Lithothamnium via fertigation (0, 5, 10, 15 and 20 L ha-1), four periods of application (30, 60, 90 and 120 days after flowering) and two production cycles, with three blocks, totaling 120 plots. The variables evaluated were: number of marketable fruits and parthenocarpic fruits per plant, average weight of marketable fruits and parthenocarpic fruits, and marketable fruit production. Application of 12 L per plant of calcium from Lithothamnium promotes a 20% increase in ‘Palmer’ mango yield in the Sub-middle São Francisco Valley. Calcium from Lithothamnium should be applied from the beginning up to 30 days after flowering of ‘Palmer’ mango in the Sub-middle São Francisco Valley. The effect of the application of calcium from Lithothamnium seaweed on ‘Palmer’ mango production varies according to doses and production cycles.

Abstract The present study was based on the analysis of 10,467 trawls of the industrial piramutaba (Brachyplatystoma vaillantii) fishing fleet of the Brazilian state of Pará, which were mapped by onboard GPS loggers (between February 2008 and September 2011) and the PREPS data from 40 vessels which were tracked by this system between 2008 and 2011. The variation in the mean monthly CPUE, based on Lomb’s periodogram, revealed a well-defined and constant cycle with a duration of approximately one year. Three environmental factors influenced this cycle. The El Niño 3.4 index had a negative correlation with the CPUE of the piramutaba fishery, with a time lag of 15 months, while monthly rainfall and the mean discharge of the Amazon River correlated strongly (r=0.89 and 0.87, respectively; p<0.001) with the CPUE, with time lags of 12 and 11 months, respectively. The spatiotemporal analysis of the distribution of the activity of the piramutaba fishing fleet indicated that the most intense area of operation of the fleet lies between latitudes 00º N and 02° N, and longitudes 047º40’ W and 049º40’ W. This area was divided into four geographic quadrants, although fishery operations were concentrated in only three of these quadrants. The study proposed a quadrimester fishing cycle with zoning in three of the quadrants, where fishing would be permitted for four months (occupation period), followed by an 8-month rest period for the recuperation of stocks, aiming at the sustainability of this fishing exploration.

Abstract This paper aims to analyze the relationships among tropical (Atlantic Meridional Mode - AMM), subtropical (South Atlantic Subtropical Gradient - SASG), and extratropical (Southern Annular Mode - SAM) teleconnection patterns, the Weddell Sea (WS) sea ice extents, and the climate in South America. Warm anomalies are observed in most of South America for maximum WS ice extent combinations (negative SAM/positive AMM and negative SAM/positive SASG composites), with an opposite signal at tropical South America for minimum WS ice extent combinations (positive SAM/negative AMM and positive SAM/negative SASG). Over Southern Argentina, colder (warmer) temperatures are seen at the negative SAM/positive SASG (positive SAM/negative SASG). Drier (wetter) conditions are found over most South America at maximum (minimum) WS ice extent combinations. Wavetrains from different Pacific and Indian Oceans regions are related to high-level anomalous cyclonic (anticyclonic) circulation over the continent at maximum (minimum) WS ice extent configuration, which explains the climate impacts found. The SASG signal displaces the anomaly circulations eastward from South America, impacting the adjacent Atlantic Ocean region more intensely concerning the other modes. The results discussed here indicated that these patterns (SAM, AMM, SASG, and sea ice extent) have significant links with the South American climate variability.

Abstract The spatial variability of physical properties, such as bulk density, penetration resistance and gravimetric moisture, obtained by applying geostatistics in precision agriculture, can effectively indicate the physical behavior of agricultural soils in longitudinal profiles. In this way, the spatial dependence of physical properties in streets of coffee plantations with different lengths was evaluated in the southern Minas Gerais, Brazil. For this purpose, five longitudinal profiles were measured in streets, each one with depths ranging from 0 to 0.60 m, in six layers of 0.10 m, being the database composed of 432 property, 144 by property, submitted to the ordinary kriging geostatistical method in order to obtain spatial variability maps using the R software. They were evaluated by the lower mean cross-validation error of theoretical models fitted by ordinary least squares (OLS), being detected in higher superficial layers, from 0 to 0.30 m, lower bulk density and lower penetration resistance, with variable gravimetric moisture in the length direction of some streets of coffee plantations, being that these properties presented different structures of spatial dependence for each street.

RESUMO: Deficiências minerais são importantes causas de perdas produtivas em criações de ruminantes, sobretudo em regiões semiáridas. Este trabalho teve como objetivo determinar as concentrações séricas de Na, K e Cl, além das concentrações salivares de Na e K em ovinos criados em uma região semiárida do Nordeste do Brasil e relatar a epidemiologia e os aspectos clínicos e patológicos de um surto de hiponatremia severa em ovinos. Para isso, amostras de soro e saliva de 55 ovinos foram coletadas em 6 diferentes fazendas da região. As concentrações de Na, K e Cl foram determinadas por teste colorimétrico, utilizando kits comerciais em analisador bioquímico semiautomático. As concentrações séricas médias variaram de 131,5±13,1mEq/L a 172,4±9,3mEq/L para Na, 6,28±1,3mEq/L a 13,9±1,4mEq/L para K e 91,6±54,8mEq/L a 113,6±1,5mEq/L para Cl. As concentrações salivares médias variaram de 119,4±9,5mEq/L a 161,8±15,2mEq/L para Na, 10,1±3,1mEq/L a 22,3±2,3mEq/L para K, e a razão Na: K variou de 6,0±1,3mEq/L a 11,8±4,1mEq/L. Esses resultados revelaram que a maioria dos ovinos criados nas fazendas desta região são marginalmente sódio deficientes. Em uma fazenda, os ovinos apresentavam um quadro clínico grave de deficiência de Na. Os principais sinais clínicos consistiam em apatia, avidez por sal, polidipsia, poliúria, tosse seca, inapetência, pica, fraqueza, dificuldade de se levantar e se locomover, emagrecimento e desidratação. À necropsia, o conteúdo ruminal estava geralmente compactado, dando ao conteúdo um aspecto de bolas de argila. Quatro ovelhas apresentaram hipertrofia das glândulas adrenais. Histopatologicamente, a zona glomerulosa apresentava-se espessa, com perda da arquitetura e desarranjo dos cordões celulares. As células epiteliais da zona glomerulosa e fasciculada eram piramidais, apresentavam citoplasma hipereosinofílico e continham núcleos hipercromáticos. Esses dados demonstram a ocorrência de deficiência de Na em diferentes graus em criações de ovinos no Estado de Pernambuco e evidencia a importância do fornecimento de NaCl para a prevenção de surtos de hiponatremia.

ABSTRACT: Mineral deficiencies are important causes of productive losses in ruminant farming, especially in semiarid regions. This study aimed to determine Na, K, and Cl serum concentrations, plus the salivary concentrations of Na and K in sheep raised in a semiarid region of Northeastern Brazil, and to report the epidemiology, clinical and the pathological aspects of an outbreak of hyponatremia in sheep. For this, serum and salivary samples of 55 sheep were collected in 6 different farms in the region. Na, K, and Cl concentrations were determined by colorimetric test, using commercial kits in a semi-automatic biochemical analyzer. The mean serum concentrations ranged from 131.5±13.1mEq/L to 172.4±9.3mEq/L for Na, 6.28±1.3mEq/L to 13.9±1.4mEq/L for K, and 91.6±54.8mEq/L to 113.6±1.5mEq/L for Cl. The mean salivary concentrations ranged from 119.4±9.5mEq/L to 161.8±15.2mEq/L for Na, 10.1±3.1mEq/L to 22.3±2.3mEq/L for K, and the ratio Na:K ranged from 6.0±1.3mEq/L to 11.8±4.1mEq/L. These results revealed that most sheep raised in the farms in this region are marginally depleted in sodium. In one farm, sheep had severe clinical signs of Na deficiency consisting of haggard appearance, craving for salt, polydipsia, polyuria, dry cough, inappetence, pica, weakness, difficulty to rise and move, severe emaciation, and dehydration. On autopsy, the ruminal content was generally impacted, giving to the content an aspect of clay balls. Four sheep presented hypertrophy of the adrenal glands. Histopathologically, the width of the zona glomerulosa was expanded, there was loss of the architecture and loss of adrenocortical cell cords. The epithelial cells in the zona glomerulosa and fasciculata were pyramidal, and contained hypereosinophilic cytoplasm and hyperchromatic nuclei. These data demonstrate the occurrence of Na deficiency in different degrees in sheep farms in the State of Pernambuco and highlight the importance of providing NaCl to avoid outbreaks of hyponatremia.
