ABSTRACT

O objetivo deste estudo foi avaliar os aspectos clínicos e patológicos da deficiência de fósforo em caprinos no semiárido de Pernambuco. Para isso, visitas técnicas foram realizadas em diferentes propriedades na microrregião do Sertão do Moxotó durante o período da estação seca. Realizaram-se exames clínicos, determinação da atividade sérica de cálcio total e ionizado, fosforo sérico, magnésio, razão Ca:P, proteína total, albumina, globulina e o percentual de cinzas ósseas. Biopsias ósseas da região hipocondríaca da 12 costela direita foram fixadas em solução de formalina a 10% e descalcificadas para análises histológicas. Os principais sinais clínicos observados nos caprinos com deficiência de fósforo foram aumento da fragilidade óssea além de desidratação, magreza, hipomotilidade ruminal, alopecia, pelos opacos, quebradiços e eriçados e osteofagia. As médias dos valores das cinzas ósseas e do teor de fósforo nos ossos estavam abaixo dos valores de referência e a correlação entre essas duas variáveis foi fortemente positiva (r=0,91); a redução da concentração do fósforo sérico foi acompanhada da redução da porcentagem desse mineral nas cinzas. Esse resultado é conclusivo para o diagnóstico de deficiência de fósforo. No exame microscópico dos fragmentos ósseos das costelas, verificou-se evidente aumento da atividade osteoclástica com áreas de reabsorção óssea e maior quantidade de tecido osteóide e de fibras colágenas na matriz óssea. Conclui-se que a deficiência de fósforo é uma doença frequente em caprinos criados em regime semi-extensivo no semiárido de Pernambuco e que a suplementação desse mineral é necessária na região estudada.(AU)


The aim of this study was to evaluate the clinical and pathological aspects of phosphorus deficiency in goats in the semiarid region of Pernambuco. For this, technical visits were carried out at different properties in the Sertão do Moxotó region during the dry season period. Clinical examinations, serum analysis and rib biopsies were carried out to determine macromineral contents. Serum concentrations of total and ionized Ca, serum and bone P, Mg, Ca:P ratio, total protein, albumin, globulin and ashes were determined. Bone biopsies were performed by surgical procedure in the hypochondriac region of the 12th right rib which were fixed in 10% formalin solution and decalcified for histological analysis. The main clinical signs in phosphorus-deficient goats consisted of dehydration, poor corporal score, ruminal hypomotility, alopecia, opaque, brittle and bristly hair and osteophagy. The averages of bone ashes and phosphorus content in bones were below the reference values and the correlation between these two variables was strongly positive (r=0.91). The reduction of the serum phosphorus concentration was accompanied by the reduction of the percentage of this mineral in the ashes. This result is conclusive for the diagnosis of phosphorus deficiency. In the microscopic examination of ribs bony fragments there was a clear increase in osteoclastic activity with areas of bone resorption and a greater amount of osteoid tissue and collagen fibers in the bone matrix. It is concluded that phosphorus deficiency is a frequent disease in goats in the semiarid region of Pernambuco, Brazil and and the supplementation of this mineral is necessary in the studied region.(AU)

ABSTRACT

Abstract Background: Low phosphorus availability is a major factor restricting rice growth. Dongxiang wild rice (Oryza rufipogon Griff.) has many useful genes lacking in cultivated rice, including stress resistance to phosphorus deficiency, cold, salt and drought, which is considered to be a precious germplasm resource for rice breeding. However, the molecular mechanism of regulation of phosphorus deficiency tolerance is not clear. Results: In this study, cDNA libraries were constructed from the leaf and root tissues of phosphorus stressed and untreated Dongxiang wild rice seedlings, and transcriptome sequencing was performed with the goal of elucidating the molecular mechanisms involved in phosphorus stress response. The results indicated that 1184 transcripts were differentially expressed in the leaves (323 up-regulated and 861 down-regulated) and 986 transcripts were differentially expressed in the roots (756 up-regulated and 230 down-regulated). 43 genes were up-regulated both in leaves and roots, 38 genes were up-regulated in roots but down-regulated in leaves, and only 2 genes were down-regulated in roots but up-regulated in leaves. Among these differentially expressed genes, the detection of many transcription factors and functional genes demonstrated that multiple regulatory pathways were involved in phosphorus deficiency tolerance. Meanwhile, the differentially expressed genes were also annotated with gene ontology terms and key pathways via functional classification and Kyoto Encyclopedia of Gene and Genomes pathway mapping, respectively. A set of the most important candidate genes was then identified by combining the differentially expressed genes found in the present study with previously identified phosphorus deficiency tolerance quantitative trait loci. Conclusion: The present work provides abundant genomic information for functional dissection of the phosphorus deficiency resistance of Dongxiang wild rice, which will be help to understand the biological regulatory mechanisms of phosphorus deficiency tolerance in Dongxiang wild rice.

ABSTRACT

We developed and evaluated a fast and simple method to obtain suitable bone samples for densitometry and chemical analysis through biopsies of the 12th rib of cattle. The postoperative recovery, dry matter intake (DMI) and average daily weight gain (ADG) was evaluated in 36 Nellore steers, nine of which were randomly selected for the control group and 27 others were rib biopsied. Every 30 days, rib biopsy was performed in nine steers, using a corded-electric pistol-grip drill coupled with a hole saw of a 3mm diameter pilot drill bit. This rib biopsy technique provided a suitable sample obtained in a fast way and allowed the surgeon to work alone with the animal slightly sedated and restrained in the crush. Dry matter intake (DMI) was not affected in biopsied animals. At the end of the experimental period (116 days) the average daily weight gain (ADG) was similar in the steers biopsied or not. The described method provided rib samples from cattle suitable for densitometry and chemical analysis of bone tissue without effects on health and performance. This information could greatly increase the accuracy for the diagnosis of phosphorus deficiency in cattle raised on pasture and allow the evaluation of bone metabolism in experimental animals.(AU)


No presente estudo foi desenvolvida uma técnica para se obter, de forma rápida e simples, amostras da 12a costela bovina por meio de biópsias. Avaliou-se a recuperação pós-operatória (durante 15 dias), o consumo de matéria seca (CMS) e o ganho de peso diário (GMD) de 36 novilhos Nelores, sendo nove animais controles e 27 submetidos à biópsia. A cada 30 dias biópsias de costelas foram realizadas em nove animais, usando uma furadeira elétrica acoplada a uma serra-copo com uma broca-guia de 3mm de diâmetro. Esta técnica de biópsia permitiu obter amostras ósseas de forma rápida, com o cirurgião operando sozinho e com os animais levemente sedados e em estação. Ao término do experimento (116 dias) o CMS e o GMD não foram afetados pelo procedimento cirúrgico. As amostras obtidas foram adequadas para exames radiográficos e subsequentes análises químicas. O conjunto de informações adquiridas com a técnica de biópsia de costelas permite aumentar a exatidão no diagnóstico da deficiência de fósforo em bovinos criados em pastagens e também realizar estudos sobre metabolismo ósseo em animais experimentais.(AU)

ABSTRACT

A retrospective study of the epidemiological and clinic-pathological aspects of cattle and buffaloes with degenerative joint disease (DJD) was conducted in the state of Pará, Brazil. From 1999 to 2014, eleven cattle and 24 buffaloes were evaluated. All the treated animals with suspected DJD underwent a clinical examination of the musculoskeletal system. In seven cattle and eight buffaloes with clinical signs of the disease postmortem examination was performed. The common clinical signs observed in both species were chronic lameness, stiff gait, postural changes, audible crackles in the affected limb, prolonged recumbency, difficulty in getting up and progressive weight loss. The lesions observed at necropsy were: irregular articular surfaces, erosion of the articular cartilage and the underlying bone tissue, and proliferation of the periarticular bone tissue with formation of osteophytes. The most affected joints in cattle and buffaloes wereof the hind limb. In buffaloes, the main predisposing factor to the onset of DJD was phosphorus deficiency. In cattle, defects of the anatomical conformation of the hind limbs, chronic trauma due to the activities performed, such as semen collection, and advanced age possibly contributed to the emergence of the disease...


Foi realizado um estudo retrospectivo sobre os aspectos epidemiológicos e clínico-patológicos em bovinos e búfalos com doença articular degenerativa (DAD) no estado do Pará, Brasil. Durante os anos de 1999 a 2014 foram avaliados 11 bovinos e 24 bubalinos. Todos os animais atendidos com suspeita clínica de DAD foram submetidos a exame clínico do sistema locomotor. Foram necropsiados sete bovinos e oito bubalinos com sinais clínicos da enfermidade. Os sinais clínicos comuns observados em ambas as espécies foram claudicação crônica, andar rígido, alterações posturais, crepitações audíveis no membro acometido, decúbito prolongado, dificuldade para levantar, e emagrecimento progressivo. As lesões articulares evidenciadas na necropsia consistiram em irregularidade da superfície articular, presença de erosão na cartilagem articular e no tecido ósseo subjacente, proliferação de tecido ósseo periarticular com formação de osteófitos. Tanto nos bovinos como nos bubalinos as articulações mais acometidas foram as dos membros posteriores. Nos bubalinos, possivelmente o principal fator predisponente ao surgimento de DAD foi à deficiência de fósforo, ao contrário dos bovinos, nos quais os defeitos de conformação anatômica dos membros posteriores, traumas crônicos em virtude da atividade exercida, como a coleta de sêmen e a idade avançada, foram o que, possivelmente, contribuíram para surgimento da enfermidade...

ABSTRACT

OBJETIVO: Avaliar associação entre ultrassonografia quantitativa de falanges da mão (QUS) e a densitometria por absorção de raio-X de dupla energia (DXA) e desses com os históricos alimentar e de fraturas. SUJEITOS E MÉTODOS: Após dois anos de acompanhamento de 270 escolares, 10 com massa óssea por QUS abaixo de -2 DP foram incluídos no estudo e avaliados com DXA. RESULTADOS: A massa óssea por DXA de L1-L4 variou de -2,8 a -1,1 DP e de corpo inteiro -2,9 e -1,2. Três estudantes apresentaram fraturas. Baixa ingestão de cálcio foi observada nos 10 casos, de fósforo em 6 e de vitamina D em 8. Não houve diferença entre os casos com massa abaixo de -2 DP nos três métodos de avaliação. Não foi observada associação entre as fraturas e o histórico alimentar, nem com os valores de massa óssea. CONCLUSÃO: Neste pequeno grupo de adolescentes houve associação entre QUS e DXA, porém sem associação entre essas avaliações e as fraturas e a ingestão de cálcio, fósforo e vitamina D.


OBJECTIVE: To evaluate the association between quantitative ultrasonography at hand phalanges (QUS) and dual energy X-ray absorptiometry (DXA), and between these methods with food intake and history of bone fractures. SUBJECTS AND METHODS:After two years of follow up of 270 schoolchildren, 10 of them, who showed bone mass below - 2 SD in QUS, were included in the present study. Laboratory results and DXA data were analyzed. RESULTS: Bone mass evaluated by DXA at L1-L4 ranged from -2.8 to -1.1 SDS, and whole body bone mass, from -2.9 to -1.2 SDS. Three children had history of non-pathological bone fractures. Dietary assessment showed low intake of calcium in 10 cases, of phosphorus in 6, and of vitamin D in 8 cases. There were no differences among the cases of bone mass below-2 SD in any of the three used methods. There was no association between history of bone fractures and food intake, and between these evaluations and bone mass. CONCLUSION: In this small group of schoolchildren there was an association between the methods QUS and DXA. However, there was no association between bone mass and the history of bone fractures, or calcium, phosphorus and vitamin D intake.

ABSTRACT

To evaluate the effect of phosphorus supplementation for goats grazing for the semiarid region, one group of 16 recently weaned Moxotó goats was supplemented with a mineral supplement containing Na, Cl, Zn, Cu, Se, Co, and P during 240 days. Another similar group was supplemented with a similar mineral supplement without P. The mean daily consumption of supplement by animal was of 7.09±2.77g and 7.67±3.14g for the groups with and without P, respectively. The mean weight gain of the P supplemented group (45.20±5.56g) was significantly higher (P<0.05) than the non-supplemented group (40.03±2.80g). The average total P in soil was 30.8mg/kg and in the pasture 0.13 percent in dry matter. These results demonstrate the occurrence of P deficiency in some areas of the Brazilian semiarid region.

ABSTRACT

O presente trabalho faz parte de um programa de pesquisa de doenças metabólicas nutricionais em bubalinos no Trópico Úmido Amazônico e, nesse contexto, objetivou-se estudar os processos osteoporóticos em bubalinos criados em sistema de pastejo na Ilha de Marajó e a relação da enfermidade com a faixa etária e a condição físico-química óssea e do cobre hepático. Foram utilizados 110 animais: 39 jovens e 71 adultos, apresentando Índice de Condição Corporal entre 1 e 2. Avaliou-se um grupo composto por animais jovens e outro por animais adultos. Análises anátomoclínica e da qualidade óssea possibilitaram subdividir cada grupo em dois subgrupos, segundo a presença ou não de manifestações osteopáticas aparentes. Do terço médio da 11ª costela direita analisou-se o cálcio, fósforo, cinza e densidade óssea e do tecido hepático determinou-se a concentração do cobre. No exame anatomopatológico, respectivamente 98,44% dos animais jovens e 96,16% dos animais adultos apresentavam algum grau de osteoporose (+, ++, +++). Foram demonstrados baixos percentuais na média do fósforo (10,69%), nas cinzas (60,24%) e na densidade (1,46 g/ml). O cobre hepático apresentou valores médios igualmente baixos (19,51 mg/kg). Os resultados mostraram que a osteoporose apresenta um quadro mais severo nos animais jovens, sendo que o processo pode estar relacionado com as baixas reservas de fósforo no tecido ósseo e do cobre no tecido hepático.


This paper is part of a research program of metabolic nutritional diseases in water buffalo in the Humid Tropical Amazon. In that context, the objective was to study osteoporotic processes in buffalo raised in a grazing system on Marajó Island and the relation of the disease with the age as well as physical-chemical bone and hepatic copper status. One hundred and ten animals were evaluated: 39 young or juvenile and 71 adults that presented Body Condition Index from 1 to 2. One group was composed by young buffalo and another by adult animals. Based on anatomical-clinical and bone quality analyses, the animals were subdivided in two sub-groups, according to presence or absence of clinical signs of apparent osteopathic. Analysis of calcium, phosphorus, ash and bone density was performed on the middle third of the 11th right rib, and the copper concentration was determined from liver tissue. Pathological anatomical findings showed that 98.44% of juvenile animals and 96.16% of adult animals, respectively, presented some degree of osteoporosis (+, ++, +++). Low average percentages were demonstrated for phosphorus (10.69%), in ashes (60.24%) and in density (1.46 g/ml). Hepatic copper presented similar low values (19.51 mg/kg). The results showed that juvenile animals presented more severe clinical sign of osteoporosis, and the pathogenesis may be related to low reserves of phosphorus in bony tissue and copper in liver tissue.

ABSTRACT

Los factores que influyen en la distribución del inóculo de hongos micorrícicos arbusculares (micelio externo y esporas) son diversos. Entre ellos pueden mencionarse la especie vegetal predominante, el pH, la humedad del suelo, la conductividad, el contenido de fósforo, nutrientes y de metales pesados. Muchos de los reportes de la literatura son contradictorios y basados en estudios realizados en zonas templadas; en condiciones tropicales es difícil determinar los factores edáficos y ambientales que estimulan la producción de inóculo y la forma en que lo hacen. Brachiaria decumbens, como especie de pasto predominante en paisajes de loma y vega en el piedemonte amazónico colombiano, ha sido poco estudiada en su relación micorrícica. En este estudio se realizó la determinación de la densidad de esporas y micelio externo en 26 zonas cubiertas con B. decumbens, correspondientes a paisajes de loma y vega. Simultáneamente se valoraron el contenido de fósforo disponible (ppm), pH y humedad relativa del suelo (por ciento). Mediante correlaciones de Spearman (rangos) y análisis de varianza (ANDEVA) de una vía por KruscallWallis, se encontró que el inóculo se distribuye de forma diferente en loma y vega, siendo mayor la densidad de esporas en loma que en vega y más homogéneo en contenido de micelio externo en vega que en loma. No se encontró efecto del fósforo disponible, el pH y la humedad del suelo sobre la densidad de inóculo de HMA.

ABSTRACT

Introdução: A hipofosfatemia é definida como fósforo plasmático menor que 2,5 mg/dl podendo ser severa se inferior a 1,0 mg/dl. Ocorre em 2 a 5 pacientes hospitalizados, sendo descrita em pacientes com insuficiência renal crônica (IRC) submetidos a tratamento dialítico intenso. O quadro clínico decorre da diminuição de 2,3-difosfoglicerato e de outros compostos energéticos do metabolismo celular (ATP), podendo resultar em diminuição da contratilidade diafragmática, rabdomiólise, disfunção hematológica, miocárdica e da parte central do sistema nervoso. Metodologia: Este trabalho é um estudo retrospectivo realizado por meio de pesquisa do prontuário do paciente em programa regular de hemodiálise na Santa Casa de Misericórdia de Marília, no período de janeiro de 2003 a março de 2004, analisando-se os exames clínicos e laboratoriais apresentados pelo paciente, bem como o resultado das intervenções de suplementação efetuadas. Discussão: Num estudo retrospectivo de três anos em 149 pacientes sob hemodiálise com bicarbonato, baixos níveis de fosfato foram encontrados em 11 (7,3).

ABSTRACT

La importancia de los hongos formadores de micorriza arbuscular en la captura de nutrimentos del suelo y su transferencia a las plantas ha sido ampliamente estudiada. Estudios de campo e invernadero han demostrado la eficiencia del consorcio Glomus sp. Zac 19 para incrementar el crecimiento de plantas hortícolas, frutales y forestales, pero no existe conocimiento sobre las especies que lo forman. Debido a esto se hizo un análisis de las esporas del consorcio y se procedió a su identificación. Las especies identificadas corresponden a Glomus albidum, G. claroides y G. diaphanum

ABSTRACT

Determinaram-se os valores de biodisponibilidade de cálcio (BDCa) de seis fontes de fósforo, usando pintos de corte de um a 20 dias de idade, pelo critério do teor de cinzas ósseas, utilizando-se o método da abscissa. Usou-se o carbonato de cálcio (CaCO3) como fonte padräo, cujo cálcio foi considerado 100 por cento disponível, para se obter uma equaçäo de regressäo linear dos teores de cinzas ósseas (Y) em funçäo do consumo de cálcio do CaCO3 (X). As seis fontes de fósforo e seus respectivos valores de BDCa (porcentagem) foram: calcário calcítico, 99,0 fosfato bicálcico, 76,4; farinha de ossos calcinada, 63,0; fosfato bicálcio semidesfluorizado, 40,4; fosfato de Araxá, 17,2 e fosfato de Patos de Minas, 13,2. Conclui-se que: há variaçäo de BDCa entre as fontes de fósforo, observando-se os mais baixos valores nos fosfatos naturais; nas avaliaçöes de fontes de fósforo devem ser determinados os valores de biodisponibilidade de fósforo e de cálcio; o uso de fontes de fósforo para suprir fósforo disponível deve também levar em conta a BDCa; estes resultados sugerem a necessidade de suplementaçäo de cálcio, empregando-se um suplemento de alta BDCa em proporçöes adequadas às fontes avaliadas neste experimento, com especial atençäo ao conteúdo de flúor dos fosfatos de rocha

ABSTRACT

This experimental work was carried out on perfused skinned hind-limbs from three groups of rats: fed-ad-libitum (FAL), phosphorus deficient (PD) and pair-weighed (PW), all of them fasted for 24 hours before the experiments. The perfusate was prepared using KRB solution to which was added bovine albumin (3 g.%), glucose (180 mg/dl), orthophosphate (0.5 mg/dl) and approximately 16-18 per cent of fresh washed rats erythrocytes. pH was adjusted to 7.40. The medium was bubbled with hunid O2-CO2 gas mixture (95/5%). Initial perfusate volume was 90 ml. 32Pi (0.5*Ci/ml) was incorporated to the medium at -15 minutes time.Parameters measured were: perfusate glucose, perfusate plasma Pi, perfusate 32Pi, perfusate plasma Pi relative specific activity, perfusate lactate and perfusate pyruvate. Samples were obtained every 15 minutes up to 90 minutes. Insulin (200 *U/ml) was added to perfusate as a bolus at 0 minutes time, in the experiments in which the effect to the hormone was appraised. The spontaneous glucose uptake was greater in the PD group than in the FAL group, but no significant difference was found between PD and PW. Insulin increased the glicose uptake in the three groups, but the difference between PD and the other two groups was not significant. The perfusate plasma Pi rose gradually in all groups. In the stage 0-30 minutes hypophosphatemia was still present, and the increase in glucose uptake determined by insulin was not significantly different from the spontaneous incorporation of the hexose to the preparations in the PD group. The spontaneous Pi release to the medium by the preparations was not significantly differ..
