ABSTRACT
Knowledge about the needs of psychiatric patients is essential for mental health care planning. However, research on met and unmet needs is still scarce, particularly in low- and middle-income countries. This study aimed to describe the patients' needs (met and unmet) at least four years after their first psychiatric hospitalization and to verify the role of demographic and clinical features as possible predictors of these needs. Patients who had their first psychiatric admission between January 1, 2006 and December 31, 2007 at an inpatient unit in the city of Ribeirão Preto, Brazil, were eligible to participate in the study. Patients were contacted and face-to-face interviews were conducted by psychologists using the Camberwell Assessment of Need. Data were analyzed using zero-inflated negative binomial regression model. Of 933 eligible patients, 333 were interviewed. The highest level of needs was related to welfare benefits (32.4%, unmet=25.5%), followed by household skills (30.3%, unmet=3.0%), psychotic symptoms (29.4%, unmet=9.0%), psychological distress (27.6%, unmet=8.4%), physical health (24.3%, unmet=5.4%), daytime activities (19.5%, unmet=16.5%), and money (16.8%, unmet=9.0%). Fewer years of schooling, living with relatives, and unemployment at the moment of the first admission were significantly associated with a higher number of both met and unmet needs in the follow-up. Unmet needs were also more often reported by patients living alone. In conclusion, socioeconomic indicators were the best predictors of needs. The unmet needs related to welfare benefits point to the need for specific social and health policies.

The objective of this study was to determine factors affecting phenotypic characteristics related to milk production and reproductive efficiency of dairy buffalo. Phenotypic records of 2,459 Murrah, Mediterranean and crossbred buffaloes from the Embrapa Eastern Amazônia herd, from 1969 to 2013 were used. Traits included: total milk production during lactation (TMP), milk production corrected for 305 days (P305); cow weight at calving (CW), fat milk percentage (F), age at first calving (AFC), calving interval (CI), calf birth weight (BW), as well as lactation (LP) and service periods (SP). Most traits were affected by genetic group as well as year and season or interaction between them. Genetic group affected F, CI, SP and CW. Very young and older cows showed poorer production traits. There was interaction between season and year for F, CI and CW. Correlations traits were generally medium to low. The principal component analysis showed that higher fat milk percentage was associated with higher percentage of Murrah breed, longer lactation period and older cows. Phenotypic characteristics in buffaloes reared in the Brazilian Amazon were significantly affected by genetic and management factors. This information can be used to help build sustainable production systems for the region and guide farmer decisions.(AU)
O objetivo deste estudo foi determinar os fatores que afetam as características fenotípicas relacionadas à produção de leite e a eficiência reprodutiva de búfalas leiteiras. Foram utilizados os registros fenotípicos de 2.459 búfalas das raças Murrah, Mediterrâneo e seus cruzamentos do rebanho da Embrapa Amazônia Oriental, de 1969 a 2013. As características incluídas foram: produção total de leite durante a lactação (PTL), produção de leite corrigida para 305 dias (P305), peso da búfala ao parto (PV), percentual de gordura do leite (G), idade ao primeiro parto (IPP), intervalo entre partos (IP), peso do bezerro ao nascimento (PN), assim como os períodos de lactação (PL) e de serviço (PS). A maioria das características foi afetada pelo grupo genético, bem como pelo ano e pela estação ou pela interação entre eles. O grupo genético afetou o G, IP, PS e PV. Búfalas muito jovens e mais velhas mostraram características de produção mais baixas. Houve interação entre estação e o ano para G, IP e PV. As correlações entre as características foram geralmente de médias a baixas. A análise de componentes principais mostrou que a maior porcentagem de gordura no leite foi associada com a maior porcentagem de sangue Murrah, com o maior período de lactação e com búfalas mais velhas. As características fenotípicas das búfalas criadas na Amazônia brasileira foram significativamente afetadas por fatores genéticos e de manejo. Essas informações podem ser usadas para ajudar a construir sistemas de produção sustentáveis para a região e orientar as decisões dos produtores.(AU)

The objective of this study was to evaluate genetic aspects related to production and reproductive efficiency of Murrah and Mediterranean buffaloes and their crosses. A ranking of bulls from Embrapa Eastern Amazonia was also composed to guide assisted mating. Birth records of 2,322 Murrah, Mediterranean, and crossbred buffaloes from the Embrapa Eastern Amazon herd, from 1953 to 2013, as well as information on production and reproductive traits were used. Genetic analyzes were performed in the WOMBAT software using the animal model with two-trait analysis. While heritability (h2) for total milk production (TMP) and fat milk percentage (F) were generally high, for reproductive traits h2 tended to be low. Genetic correlations for TMP with the other traits were low and negative, except for TMP with calving interval (CI) and service period (SP) in the Mediterranean breed and with age at first calving (AFC) and SP in crossbred, which were positive and high. Bull 1001 had high predicted transmitting ability (PTA) for TMP, so it should transmit a greater volume of milk to his offspring, although it had a lower PTA for F. There was sufficient variability within the herd to work with genetic management for both production and reproductive efficiency.(AU)
O objetivo deste estudo foi avaliar os aspectos genéticos relacionados à produção e à eficiência reprodutiva de búfalas das raças Murrah, Mediterrâneo e suas cruzas. Uma classificação de touros da Embrapa Amazônia Oriental também foi composta para orientar os cruzamentos assistidos. Foram utilizados 2.322 registros de nascimento de búfalas das raças Murrah, Mediterrâneo e cruzadas do rebanho da Embrapa Amazônia Oriental, de 1953 a 2013, bem como características produtivas e reprodutivas. As análises genéticas foram realizadas pelo software Wombat, utilizando-se o modelo animal com análise de duas características. Enquanto a herdabilidade (h 2 ) para a produção total de leite (PTL) e para a porcentagem de gordura (G) foi alta, para as características reprodutivas a h 2 tendeu a ser baixa. As correlações genéticas da PTL com as demais características foram baixas e negativas, exceto para a PTL com intervalo entre partos (IP) e período de serviço (PS) na raça Mediterrâneo e com idade ao primeiro parto (IPP) e PS nas cruzadas, que foram positivas e altas. O touro 1001 apresentou alta capacidade de transmissão predita (CTP) para a PTL, então deve transmitir um maior volume de leite para seus descendentes, embora com um menor conteúdo transmissível de CTP para G. Portanto, existe variabilidade suficiente dentro do rebanho para trabalhar com o manejo genético para a produção e a eficiência reprodutiva.(AU)

Hypoxemia is a major complication of field anesthesia and no studies regarding this occurrence in mules has been done. Thus, the aim of this study was to evaluate intranasal oxygen supplementation (IOS) in mules (Equus caballus x Equus asinus) anesthetized with ketamine/butorphanol/guaifenesin combination. For this, we used six male, adult mules (322±29kg) which underwent premedication (MPA) with 0.2mg/kg of midazolam intramuscularly after 15 minutes, 0.02mg/kg detomidine IV 5 minutes after, induction IV with combination of ketamine (2mg/mL), butorphanol (22.5mg/mL), and guaifenesin (50mg/mL) (K/B/G) until lateral decumbency. Maintenance was done with the same anesthetic combination. The animals were submitted twice to the protocol described above, 20 days apart, forming two groups. CG: MPA, induction (0.92±0.24mL/kg (mean±SD)), and maintenance (2.2±0.2mL/kg/h) without SIO; TG: MPA, induction (0.98±0.17mL/kg), and maintenance (2.3±0.4mL/kg/h) with IOS flow 40mL/kg/h. During anesthesia arterial blood was collected every 20 minutes (T0, T20, T40, and T60) for blood gas analysis. Data analyzed by ANOVA followed by the Bonferroni test. P<0.05 was considered significant. Hypoxemia of the animals in the CG in periods (59±5; 55±5; 53±7; 49±8) with lower averages than the TG (160±4, 115±34, 92±25, 81±19) was observed, demonstrating that IOS increases PaO2 avoiding the occurrence of hypoxemia.(AU)
A hipoxemia é uma das principais complicações da anestesia a campo, e em muares não existem estudos a respeito dessa ocorrência. Assim, objetivou-se avaliar a suplementação intranasal de oxigênio (SIO) em muares (Equus caballus x Equus asinus) anestesiados com cetamina/butorfanol/guaifenesina associados. Para isso, foram utilizados seis muares, macho e adultos (322±29kg), submetidos à medicação pré-anestésica (MPA) com 0,2mg/kg de midazolam por via intramuscular, após 15 minutos, 0,02mg/kg de detomidina por via intravenosa, após cinco minutos, indução com administração intravenosa da associação de cetamina (2mg/mL), butorfanol (22,5 µg/mL) e guaifenesina (50mg/mL) em solução de glicose a 5% (C/B/G) até o animal assumir o decúbito lateral. A manutenção foi realizada com a mesma associação anestésica. Os animais foram submetidos duas vezes ao protocolo descrito anteriormente, com intervalo de 20 dias, formando dois grupos experimentais. GC -MPA, indução (0,92±0,24mL/kg (média±DP)) e manutenção (2,2±0,2mL/kg/h) sem SIO; GT - MPA, indução (0,98±0,17mL/kg) e manutenção (2,3±0,4mL/kg/h) com SIO, fluxo de 40mL/kg/h. Durante a anestesia, foi colhido sangue arterial a cada 20 minutos (T0, T20, T40 e T60) para hemogasometria. Os dados foram analisados pela ANOVA, seguidos pelo teste de Bonferroni. Valores de P<0,05 foram considerados significativos. Foi observada hipoxemia (PaO2<60mmHg) dos animais no GC nos tempos avaliados (T0= 59±5; T20= 55±5; T40= 53±7; T60= 49±8), com médias menores que as do GT, (160±4; 115±34; 92±25; 81±19, respectivamente), o que demonstrou que a suplementação intranasal de oxigênio aumenta a PaO2, evitando a ocorrência de hipoxemia.

RESUMO O presente estudo teve como objetivo analisar o efeito alelopático e o rótulo dos produtos vegetais contidos nas garrafadas comercializadas no mercado municipal de Montes Claros - MG. Adquiriram-se oito garrafadas que foram utilizadas para tratar, cada uma, 20 sementes de alface (Lactuca sativa L.) dispostas em placas de Petri sobre papel saturado com 4mL do conteúdo de cada garrafada em 04 concentrações: 12,5; 25; 50; e 75%. O controle positivo foi realizado com solução de sulfato de zinco a 1%, além dos controles: água mineral, água da torneira, e água destilada. As placas de Petri foram lacradas com filme plástico, cobertas com saco plástico e incubadas em escuro por sete dias à temperatura média de 27,2°C e na umidade média de 54%. Após 7 dias, mediu-se o comprimento da radícula e do hipocótilo (mm) de cada uma das plântulas e quantificou-se o número de sementes que germinaram. Os dados foram submetidos à análise de variância pelo software Sisvar, sendo os resultados comparados pelo Teste Scott-Knott ao nível nominal de 5%. Os resultados do teste de germinação indicaram que houve efeito significativo das garrafadas sobre a germinação das sementes de Lactuca sativa L., onde o percentual de germinação das sementes foi inversamente proporcional ao aumento da concentração das garrafadas. Portanto, observou-se que as garrafadas apresentaram potencial alelopático ao inibirem a germinação das sementes de alface.
ABSTRACT This study aimed to analyze the allelopathic effect and label of plant products put in bottles commercialized in the municipal market of Montes Claros - MG. Eight bottles were employed to treat, each one, 20 lettuce seeds (Lactuca sativa L.) placed at Petri plaques over saturated paper with 4mL of the content of each bottle in 04 concentrations of 12.5; 25; 50; 75% for each bottle, 1% of zinc sulfate solution (positive control) and 3 negative control groups (containing mineral water, tap water and distilled water). The Petri plaques were sealed with plastic film, covered with plastic bag and incubated in the dark for seven days at an average temperature of 27.2°C and average humidity of 54%. After 7 days, it was measured the length of the radicle and the hypocotyl (mm) of each one of the seedlings and the number of seeds that germinated was quantified. The data were submitted to analysis of variance by Sisvar software and the results were compared by Scot-Knott Test at a nominal level of 5%. The results of the germination test indicated that there was a significant impact of the bottles in the germination of the lactuca sativa L. seeds, where the percentage of seeds germination was inversely proportional to the concentration increase in the analyzed bottles. Therefore, it has been observed that the bottles presented allelopathic potential when they inhibited the germination of lettuce seeds.

A metadona é um opioide pouco utilizado na medicina veterinária, e há, ainda, questionamentos quanto ao seu uso. Desse modo, comparou-se o emprego da metadona, administrada pelas vias IM e IV, e avaliaram-se seus efeitos sobre as características cardiorrespiratórias e os tempos de extubação e recuperação em cadelas submetidas à ovariossalpingo-histerectomia. Utilizaram-se 16 cadelas, pré-medicadas com levomepromazina, 0.6mg/kg, IM. Após 20 minutos, a indução anestésica foi feita com propofol, 5mg/kg, IV, e a manutenção com isoflurano. Transcorridos 10 minutos, os animais receberam metadona, 0.3mg/kg, pelas vias IM - grupo GIM - e IV - grupo GIV. As mensurações das frequências cardíaca (FC) e respiratória (FR), pressão arterial média (PAM), temperatura esofágica (TE), pressão parcial de dióxido de carbono (EtCO2) e saturação de oxi-hemoglobina (SpO2) foram registradas antes da administração do opioide (T0), após 20 minutos (T1) e a cada 10 minutos da administração até 60 minutos (T2 a T5). Usou-se a análise de perfil (5%). Com relação à FC, PAM, FR, EtCO2, TE e SpO2, não foram observadas diferenças significativas entre grupos e momentos. Observaram-se tempos de extubação e recuperação maiores no GIV. É possível concluir que a administração IV e a IM da metadona não produzem alterações nas características cardiorrespiratórias em cadelas.
Methadone is a little used opioid in veterinary practice, and there are still questions about its use. The objective of this study was to evaluate the effects of intramuscular (IM) or intravenous (IV) administration of methadone on cardiopulmonary parameters and times of extubation and recovery in female dogs submitted to ovariohysterectomy. Sixteen adult female dogs were used and premedicated with levomepromazine (0.6mg/kg, IM). After 20 minutes, propofol (5mg/kg, IV) was used for induction and anesthesia was maintained with isoflurane. After 10 minutes, methadone at 0.3mg/kg was administered intravenously in IVG and intramuscularly in IMG. The measurement of heart (HR) and respiratory rates (RR), median arterial pressure (MAP), esophagic temperature (ET) and concentration of end-tidal carbon dioxide (PE'CO2) was performed immediately before the administration of the opioid (T0), after 20 minutes (T1) and then at 10-minute intervals (T2, T3, T4 and T5). The statistical analysis used was profile (5%). HR, APM, RR, PE'CO2, BT and SpO2 did not differ significantly among times or between groups at any time. Times of extubation and recovery were higher in IVG. It is possible to conclude that IV and IM administration of methadone did not produce changes in the cardiorespiratory parameters of that specie.

O presente experimento foi conduzido com o objetivo de avaliar a porcentagem de inclusão da espécie forrageira Gliricidia sepium (Jacq.) Walq na confecção do sal forrageiro de gliricídia, por meio de características de carcaça e de não componentes da carcaça de cordeiros. Foram utilizados 30 cordeiros mestiços da raça Santa Inês, não castrados, com aproximadamente 180 dias de idade, peso vivo médio de 25kg, confinados, num delineamento experimental inteiramente ao acaso, com cinco tratamentos e seis repetições, em que os tratamentos foram constituídos de zero (100% de NaCl), 93, 95, 97 e 99% de inclusão de feno de gliricídia (7, 5, 3 e 1% de NaCl na formulação do sal forrageiro, respectivamente). A suplementação com sal forrageiro de gliricídia não afetou (P>0,05) o peso vivo ao abate em jejum (28,39kg), peso de carcaça quente (9,76kg), rendimento de carcaça quente (34,12%), o peso de carcaça fria (9,42kg), o rendimento de carcaça fria (32,95%), as perdas de peso por resfriamento (3,40%), assim como o peso de vísceras brancas (2,19kg) e o peso de vísceras vermelhas (1,29kg). Porcentagem de inclusão de até 99% de gliricídia na confecção de sal forrageiro não altera (P>0,05) as características de carcaça e de não componentes da carcaça de cordeiros.
The experiment was conducted to evaluate the inclusion of Gliricidia sepium (Jacq.) Walq forage species for the confection of the fodder salt gliricidia according to the characteristics of carcass and non-carcass components of lambs. Thirty confined, not castrated crossbred Santa Inês lambs, ageing approximately 180 days, with mean live body weight of 25kg, were distributed in a completely randomized design, with five treatments and six repetitions. Treatments were zero (100% NaCl), 93, 95, 97 and 99% inclusion of gliricidia hay (7, 5, 3 and 1% NaCl in the formulation of fodder salt, respectively). The supplementation with gliricidia fodder salt did not affect (P>0.05) the fasting live body weight (28.39kg), hot carcass weight (9.76kg), hot carcass yield (34.12%), cold carcass weight (9.42kg), cold carcass yield (32.95%), chilling loss (3.40%), or white (2.19kg) and red viscera weight (1.29kg). The inclusion of up to 99% gliricidia in the production of fodder salt did not affect (P>0.05) the characteristics of carcass and non-carcass components of lambs.

Chagas' myocardiopathy, caused by the intracellular protozoan Trypanosoma cruzi, is characterized by microvascular alterations, heart failure and arrhythmias. Ischemia and arrythmogenesis have been attributed to proteins shed by the parasite, although this has not been fully demonstrated. The aim of the present investigation was to study the effect of substances shed by T. cruzi on ischemia/reperfusion-induced arrhythmias. We performed a triple ischemia-reperfusion (I/R) protocol whereby the isolated beating rat hearts were perfused with either Vero-control or Vero T. cruzi-infected conditioned medium during the different stages of ischemia and subsequently reperfused with Tyrode's solution. ECG and heart rate were recorded during the entire experiment. We observed that triple I/R-induced bradycardia was associated with the generation of auricular-ventricular blockade during ischemia and non-sustained nodal and ventricular tachycardia during reperfusion. Interestingly, perfusion with Vero-infected medium produced a delay in the reperfusion-induced recovery of heart rate, increased the frequency of tachycardic events and induced ventricular fibrillation. These results suggest that the presence of parasite-shed substances in conditioned media enhances the arrhythmogenic effects that occur during the I/R protocol.

ABSTRACT
Foram avaliados registros de manejo reprodutivo de búfalos das raças Jafarabadi, Murrah, Mediterrâneo, Carabao e Tipo Baio, bem como seus mestiços, no período de 1983 a 2005. Estudaram-se as características reprodutivas: idade à primeira cria (média de 1052,52±120,45 dias), intervalo de partos (média de 399,69±23,78 dias), eficiência reprodutiva (média de 91,09±1,89%), fertilidade real adaptada (média de 29,30±4,40 quilogramas de bezerro parido por ano), produtividade ao primeiro parto adaptada (média de 33,75±6,89 quilogramas) e produtividade acumulada adaptada (média de 22,86±6,55 quilogramas de bezerro parido por ano). Foram verificadas influências do ano de parto e o grau de sangue da fêmea sobre as características estudadas, o que indica que tais efeitos devem ser incluídos na avaliação genética e na seleção dos animais. Os índices produtivos utilizados mostraram-se de grande valia para a seleção, devendo ser mais estudadas suas interações relativas ao desempenho geral do rebanho.
We evaluated records of reproductive management Jaffarabadi buffalo breeds, Murrah, Mediterranean, Carabao and Baio types, and their crosses, in the period from 1983 to 2005. We studied the following reproductive characteristics: Age at first calving (mean 1052.52±120.45 days), calving interval (399.69±23.78 mean days), Reproductive Efficiency (average 91.09±1, 89%), Real Adapted Fertility (average 29.30±4.40kg calf calved each year), the First Labor Productivity Adapted (mean 33.75±6.89kg) and Accumulated Productivity Adapted (mean 22.86±6.55kg calf calved each year). Influences were observed in the year of delivery and degree of blood on the female traits, suggesting that such effects should be included in genetic evaluation and selection of animals. The production indices used were of great value for the selection, and should be well studied for their interactions with the overall performance of the herd.

The effect of substitution of equine chorionic gonadotropin (eCG) by follicle stimulating hormone (FSH) in synchronization protocols of ovulation in dairy goats was evaluated. Twelve goats received intravaginal sponges impregnated with 60mg of medroxyprogesterone acetate (MAP) for 10 days. The sponges were removed and the animals were distributed into two groups (G): G1 (n=6) treated with 0.5mL of a synthetic analogue of PGF2 α and 100 IU of eCG for each 10kg weight, intramuscular injection (IM); and G2 (n=6) treated with 0.5mL of a synthetic analogue of PGF2α and 20mg of FSH (IM). All animals were monitored for estrus detection with aid of a ruffian after sponge removal. The ovarian dynamics were analyzed by ultrasound, since six hours after sponge removed. Each animal was analyzed in time elapsed of six hours until 12 hours after ovulation detection. For data analyses, the Wilcoxon test and variance analyses were used. There was not difference between the analyzed parameters (P>0.05). In this way, eCG can be replaced by FSH in synchronization protocols of ovulation in dairy goats.

Clinically significant chromosomal abnormalities occur in about 1 percent of children born alive. The objective of this work was to offer the patients and the families in the community for the service of the Integrated Clinic of Uniara Health (Araraquara and region), the examination of cariotype (cytogenetic study) for confirmation or exclusion of the diagnostic suspicion of chromosomal abnormalities as well as information (genetic counseling) for the prevention of occurrence and/or recurrence of these anomalies. In the period of one year and four months these were carried out in the Integrated Clinic of Uniara Health and directed for the Laboratory of Cytogenetic Human of the same institution in 66 cytogenetic studies. In 44 patients (66.6 percent) the results were normal. In 22 (33.3 percent) examinations, alterations were found, meaning that the respective clinical pictures are decurrent of chromosomic alterations. The first cause within alterations noted was Down syndrome with a total of 15 examinations or 68.1 percent, the second cause of chromosomal anomaly was the Turner syndrome where the most important factor is 45, X, where 2 karyotypes of this type or 9.1 percent were found, syndromes as (Eduards syndrome, Patau syndrome, 3p- syndrome, 4p- syndrome and 6p-syndrome) diagnosed in our laboratory appeared less frequently corresponding to 22.7 percent of the studied anomalies. The work carried out constitutes a necessary diagnosis of the main chromosomal abnormalities through a low cost technique; it can be carried out easily and is reliable, making the cytogenetic examination available to the community and contributing significantly to the quality of life of patients.
Las anormalidades cromosómicas, clínicamente significativas, se presentan en aproximadamente 1 por ciento de los niños nacidos vivos. Este trabajo tiene el objetivo de ofrecer a los pacientes y /o a sus familiares el servicio de la Clínica Integrada de la Salud de Uniara (Araraquara y Región), el examen de cariotipo (estudio citogenético) para la confirmación o la exclusión de sospecha de anomalías cromosomales diagnosticadas, así como otorgar información (consejo genético) para la prevención de las posibles anomalías y /o la repetición de éstas. En un año y cuatro meses fueron realizados 66 estudios de citogenética en la Clínica Integrada de Uniara, dirigida por el Laboratorio de Citogenética Humana de la misma institución. En 44 pacientes (66,6 por ciento) los resultados fueron normales. En 22 (33,3 por ciento) de los exámenes, se encontraron alteraciones, compatibles con alteraciones cromosómicas. La primera causa de anomalías cromosómica fue el síndrome de Down, totalizando 15 exámenes (68,1 por ciento), la segunda causa fue el síndrome de Turner, con dos cariotipos (9,1 por ciento) en la forma más importante 45, X. Por otra parte, se encontró que los síndromes de Eduards, de Patau, 3p-síndrome de Down, síndrome 4p-6p, diagnosticados en nuestro laboratorio, presentaban baja frecuencia de aparición, representando el 22,7 por ciento de las anomalías estudiadas. Este trabajo permitió realizar un diagnóstico preciso de las anomalías cromosomales, principalmente a través de una técnica de bajo costo, fácil ejecución y buena confiabilidad, técnicas que están disponibles para el examen citogenético para la comunidad y así contribuir de manera significativa en la calidad de vida de los pacientes.

Descrevem-se os aspectos clínicos da dilatação cística do úraco e uroperitônio em cinco touros. Os animais apresentaram, em datas distintas, distensão abdominal e diminuição da ingestão de alimentos e água, até culminar com inapetência, cerca de duas semanas após o aparecimento dos primeiros sintomas. Ocorreu distensão abdominal bilateral progressiva, que, no início do processo, era discreta e restrita ao quadrante inferior do abdômen; com cerca de duas semanas de evolução, o abdômen assumiu forma arredondada semelhante à pera. Observou-se bruxismo, atonia ruminal e desidratação. A abdominocentese revelou a presença de líquido amarelado com concentração de ureia superior a 200mg/dL. A concentração de ureia no soro sanguíneo variou de 220 a 280mg/dL e a creatinina de 65 a 82mg/dL. A ligadura do divertículo do úraco próximo ao vértex da bexiga foi eficaz nos quatro touros operados.
The clinical findings and outcomes in five bulls with a perforation or rupture of the urachal diverticulum are described. All the bulls had a dilated round or pear-shaped abdomen, bruxism, ruminal atony, and dehidration. In all the bulls, abdominocentesis yielded a stream fluid and the serum concentrations of urea and creatinine were 220 to 280mg/dL and 65 to 82mg/dL, respectively. Peritoneal fluid concentration of urea was higher than 200mg/dL. In fours bulls, urachal diverticulums were closed next to the cranial pole of the bladders. After the surgery, the recovery was effective.

In medical sciences, any experimental animal model should be reproducible and adequate to the purpose of simulated human physiological response. In bone injury response research, when bone substitutes are in use, it is of primary importance that studied defects fail to heal unless treated with the tissue engineering therapy under study. This failure defines the concept of "critical size defect" (CSD) wich has different limits according to the animal species used and the location of the defect. Although this is a basic concept, when the aim of the study is to investigate the interface Bone-Biomaterial, it is of primary importance to obtain as much contact area as possible. In order to do so, we propose a modified surgical approach to the classical bi-parietal round sub-critical defect model in rabbit vault.
En las ciencias médicas, cualquier modelo animal de experimentación debe ser reproducible y ajustado al propósito de simular la respuesta fisiológica humana. En la investigación de la respuesta a la lesión ósea, cuando son utilizados sustitutos óseos, es de gran importancia el estudio de defectos que no logran sanar, a menos que sean tratados con terapia de ingeniería de tejidos. Este fracaso define el concepto de "defecto de tamaño crítico" (CDS) el cual tiene límites diferentes según la especie animal utilizada y la ubicación del defecto. Aunque se trata de un concepto básico, cuando el objetivo del estudio es investigar la interfaz hueso-biomaterial, es de primordial importancia obtener la máxima superficie de contacto que sea posible. Para ello, se propone una modificación en el enfoque quirúrgico del modelo clásico de defecto de tamaño subcrítico biparietal en la bóveda de conejo.

Parâmetros baseados na probabilidade de origem do gene foram usados para descrever a variabilidade em uma população de búfalos da Embrapa Amazônia Oriental. A magnitude dos resultados foi de média a baixa (por volta de 20 animais), sugerindo que poucos fundadores contribuiriam para a formação da população. Dentre os 20 ancestrais que mais aportam genes aos machos - representando ao todo 71 por cento dos alelos -, 39 por cento, 26 por cento e 5 por cento, respectivamente, são as contribuições marginais das raças Murrah e Mediterrâneo e seus mestiços. Para as fêmeas, em que os 20 ancestrais aportam 67,5 por cento dos genes, 42 por cento e 26 por cento, respectivamente, são as contribuições marginais das raças Murrah e Mediterrâneo.
Parameters based on the probability of gene origin were used to describe genetic variability in a buffalo population from the Embrapa Amazônia Oriental, Belém, Pará, Brazil. The parameters generated medium to low values (around 20 animals) and suggested low founder representativeness. From the 20 ancestors that gave more genes to males (with 71 percent of alleles), genetic contributions were 39 percent, 26 percent, and 5 percent, respectively, for Murrah, Mediterraneo, and crossbreds. For females, these values were 42 percent and 26 percent for Murrah and Mediterraneo breeds.

Dados de 1.182 registros de produção de fêmeas bubalinas da raça Murrah e seus mestiços, parindo no período de 1967 a 2005, foram utilizados para estimação de parâmetros genéticos utilizando-se o método de máxima verossimilhança restrita. O modelo animal utilizado para estimação de componentes de variância incluiu os efeitos fixos de rebanho, ano e época de parto, ordem de parto e duração da lactação e os efeitos aleatórios do animal, e ambiente permanente e temporário. As estimativas de herdabilidade foram 0,25, 0,18, 0,08 e 0,09, para produção de leite, produção de gordura, duração da lactação e produção de leite por dia de intervalo de parto, respectivamente. As estimativas de repetibilidade foram 0,33, 0,29 e 0,10 para produção de leite, produção de gordura e duração da lactação, respectivamente. As correlações genéticas entre produções de leite e gordura, produção de leite com duração da lactação, produção de leite com produção de leite por dia de intervalo de partos, produção da gordura com duração da lactação, produção de gordura com produção de leite por dia de intervalo de partos e duração da lactação com produção de leite por dia de intervalo de partos foram 0,93; 0,76; 0,99; 0,89; 0,87 e -0,27, respectivamente. Os resultados demonstram que ganhos genéticos podem ser obtidos pela seleção das produções de leite e gordura.
Data from 1,182 records of Murrah females buffaloes and their crossbreds, calving from 1967 to 2005, were used to estimate genetic parameters by maximum restricted likelihood method. An animal model used to estimate variance components, included the fixed effects of herds, year and season of calving, order of parity, and length of lactation as covariables; and random effects of animal, permanent, and temporary environment. The estimate of heritability to milk yield, fat yield, length of lactation, and milk yield per day of calving interval were 0.25, 0.18, 0.08, and 0.09 respectively. Estimate of repeatability for milk yield, fat yield, and length of lactation were 0.33, 0.29, and 0.10, respectively. The genetic correlations between milk yield and fat yield, milk yield and length of lactation, milk yield and milk yield per day of calving interval, fat yield and length of lactation, fat yield and milk yield per day of calving interval, and length of lactation and milk yield per day of calving interval were 0.93, 0.76, 0.99, 0.89, 0.87, and -0.27, respectively. These results showed that genetic gains may be obtained by selecting to milk and fat yields.

Empregou-se a associação midazolam e detomidina para indução de anestesia com cetamina em 16 potros, machos e fêmeas, entre três e seis meses de idade, distribuídos aleatória e equitativamente em dois grupos (GI e GII). A todos os animais foram administrados midazolam, via intramuscular, na dose de 0,2mg/kg, e após 15 minutos, detomidina, via intravenosa, na dose de 0,02mg/kg. Os animais do GII receberam cetamina pela via intravenosa, dose 2,0mg/kg, três minutos após a administração de detomidina. Quinze minutos após o midazolam, ocorreram sedação e ligeira ataxia, e dois minutos após a administração da detomidina, decúbito lateral em todos os potros, com miorrelaxamento e presença dos reflexos de deglutição e miorrelaxamento, anal e oculo-palpebral. A associação midazolam/detomidina e cetamina provocou ausência dos reflexos de deglutição. Para todos os animais, o tempo de recuperação foi de 45-60 minutos, e temperatura retal e frequência respiratória permaneceram estáveis. Ocorreram bradicardia, bloqueio atrioventricular de segundo grau e aumento das pressões arteriais sistólica, diastólica e média após dois minutos da administração da detomidina. A associação midazolam/detomidina e cetamina demonstrou ser um método eficiente e seguro para a anestesia de potros hígidos.
A combination of midazolam, 0.2mg/kg body weight given via intramuscular, and detomidine, 0.02mg/kg body weight given via intravenous (IV), was evaluated as a method for induction of anesthesia with ketamine, 2.0mg/kg body weight given via IV in foals. Sixteen male and female foals aging from three to six-month old were distributed into two groups. Both groups were first injected with midazolam and with detomidine 15 minutes later. Three minutes later, ketamine was injected in the foals. Sedation and light ataxia were observed 15 minutes after midazolam administration. Bradycardia, atrioventricular block, increased blood pressure, lateral recumbency, and muscle relaxation were observed two minutes after detomidine. At that time, the oculopalpebral, anal, and cogh reflexes were present. The association of midazolam/detomidine and ketamine caused absence of the swallow reflexes. The recovery time was from 45 to 60 minutes for animals from GI and GII groups, respectively. Respiratory rate and body temperature remained unchanged. The combination of midazolam/detomidine and ketamine is a safe, good, and efficient method for anesthesia in healthy foals.

Foram realizados estudos empregando-se analgésicos por via epidural e subcutânea em cadelas de diferentes raças e idades, submetidas à castração mediante celiotomia. Vinte animais foram tranquilizados e anestesiados com tiletamina-zolazepam, e aleatoriamente distribuídos em quatro grupos (n=5), de acordo com o fármaco e a via de administração. Os do grupo morfina (GM) foram submetidos à anestesia epidural no espaço lombossacro, com morfina (0,1mg/kg) associada ao cloreto de sódio a 0,9 por cento. Aos do grupo xilazina (GX), foram administrados xilazina (0,2mg/kg) e cloreto de sódio a 0,9 por cento. Os do grupo meloxicam (GME) receberam 0,2mg/kg do anti-inflamatório meloxicam associado ao cloreto de sódio a 0,9 por cento, injetado pela via subcutânea. Os do grupo-controle (CG) receberam apenas cloreto de sódio a 0,9 por cento. O volume final para as injeções epidurais foi padronizado para 0,3mL/kg. A mensuração inicial da concentração de cortisol plasmático, do ritmo cardíaco, da frequência respiratória e os parâmetros comportamentais foram registrados imediatamente antes do procedimento cirúrgico (M1). Registros adicionais foram apresentados às 2, 6, 12 e 24 horas após o procedimento cirúrgico (M2, M3, M4 e M5, respectivamente). As variáveis comportamentais foram avaliadas por meio de sinais clínicos e seus respectivos escores. Em GX foram observadas depressão respiratória, bradicardia e concentração de cortisol mais alta do que o registrado no GM. A analgesia obtida pelo meloxicam foi considerada ineficiente. É possível concluir que a morfina, via epidural, promoveu menor incidência de efeitos colaterais e melhor analgesia e bem-estar animal.
The use of analgesics by epidural and subcutaneous way in bitches submitted to surgical sterilization by laparotomy was evaluated. Twenty females dogs of different ages and breeds were sedated and anesthetized with a combination of tiletamine-zolazepam and randomly distributed into four experimental groups of five animals each. Through the epidural space, the animals of each group received 0.1mg/kg of morphine (MG) or 0.2mg/kg of xylazine (XG); while the control group (CG) received a 0.9 percent solution of chloride sodium. The final volume stabilished for lumbosacral epidural injections was 0.3mL/kg. The dogs of meloxicam group (MEG) subcutaneously received 0.2mg/kg of the drug. The initial measurement of plasmatic cortisol concentration, heart and respiratory rates, and behaviour parameters were evaluated as soon as the surgical procedure had finished (M1). These evaluations were repeated after 2, 6, 12, and 24 hours of the post-operative period (M2, M3, M4, and M5 respectively). The behaviour parameters were evaluated by clinical signs and respective scores. Values of cortisol concentration were higher in the xylazine group than the ones registered in the morphine group. Meloxicam failed to provide pain control. Epidural use of morphine guaranteed fewer side effects and better pain control.

Toxoplasma gondii infection may lead to important pathological questions, especially in rural areas, where several sources of infection exist. Therefore, it is important to determine risk factors in order to establish adequate prophylactic measures. The present study aimed to assess the prevalence and risk factors involved in human toxoplasmosis infection in a rural community, in Eldorado, Mato Grosso do Sul State, Brazil. This community was composed of 185 farms - with 671 inhabitants - from which 20 were randomly chosen. In these farms, blood samples were collected from rural workers, who also answered a risk factor questionnaire. Serum samples were analyzed by means of direct agglutination test for the detection of anti-Toxoplasma gondii antibodies. From 73 samples collected, 79.45% were positive. None of the studied variables was significantly associated with the prevalence of the infection. However, among the individuals who reported eyesight impairments, 94.4% had anti-T. gondii antibodies, compared with 74.0% who did not report eyesight changes (p = 0.0594). Moreover, most individuals in the study (68.20%) were older than 18 years and presented 84.44% positivity, compared with 66.67% of positive individuals younger than 18 years old. We were able to conclude that a high prevalence of antibodies did not imply significant associations with the risk factors studied.(AU)

Clinical and behavioral effects of intravenous injection of romifidine (60mcg/kg) or amitraz (0.4mg/kg) were compared in six horses, over 120 min. Romifidine caused head ptosis (HP), reduced respiratory rate (RR) and ileo-cecal sphincter activity (IC) until 120 minutes; produced posture changes (PC) until 90 minutes, upper eyelid drop (ED) and sedation (SD) until 60 minutes, intestinal motion (IM) reduction and lower lip drop (LD) until 45 minutes. Amitraz reduced heart rate (HR), RR, IM and IC, and promoted HP, ED, LD, penis drop (PD) and sedation with posture changes until 120min. At 90min amitraz produced HP and ED more intensively than romifidine. The LD was similar between 45 and 60 minutes. Romifidine produced intense sedation at 10min while amitraz sedation was more significant between 90 and 120 minutes. It is concluded that both romifidine and amitraz can produce strong sedation until 60 and 120 minutes, respectively. Though amitraz sedation and posture changes had a later onset related to romifidine, these effects lasted longer
Compararam-se os efeitos sedativos e clínicos em seis eqüinos tratados com romifidina (60mcg/kg) ou amitraz (0,4mg/kg), pela via intravenosa, durante 120 minutos. A romifidina promoveu ptose da cabeça (PC), reduziu a freqüência respiratória (FR) e o movimento da válvula íleo-cecal (MC) durante 120 minutos, provocou alteração postural (AP) por 90 minutos, induziu ptose palpebral (PP) e sedação (SD) por 60 minutos, diminuiu a motilidade intestinal (MI) e causou ptose labial (PL) durante 45 minutos. O amitraz reduziu a freqüência cardíaca (FR), FR, MI e MC e provocou PC, PP, PL, prolapso peniano (PP) e sedação com alteração postural por 120 minutos. Aos 90 minutos, o amitraz induziu a PC e a PP mais intensamente que a romifidina; o mesmo ocorreu entre 45 e 60 minutos para PL. A romifidina produziu sedação maior aos 10 minutos; para o amitraz, a sedação foi mais intensa entre 90 e 120 minutos. Conclui-se que a romifidina e o amitraz produzem sedação intensa por 60 e 120 minutos, respectivamente. A sedação e as alterações posturais induzidas pelo amitraz foram de início tardio, porém tiveram maior duração
