A insuficiência renal aguda (IRA) é uma patologia que apresenta alta incidência na população e elevada morbimortalidade. Apesar de todos os avanços terapêuticos já obtidos, essas taxas ainda continuam elevadas. Uma possível alternativa, atualmente sugerida, seria o transplante de células-tronco. O processo regenerativo das células-tronco mesenquimais (CTMs) já foi demonstrado em diversos modelos experimentais e em alguns ensaios clínicos. O mecanismo de ação mais sugerido é a ação parácrina das CTMs na área lesada. Ainda, sabe-se que nesse ambiente, citocinas pró-inflamatórias, como TNF-α e IFNγ, ativam as CTMs para seu papel reparador. O presente estudo busca analisar o papel do IFNγ na ativação das CTMs em modelos renais. As CTMs de animais nocautes para receptor de IFNγ (IFNγR KO) e de animais selvagens (controle/ C57/Bl6) foram isoladas do tecido adiposo. Essas células foram caracterizadas por imunofenotipagem e diferenciação em adipócitos e osteócitos. A lesão renal aguda foi obtida através do clampeamento dos pedículos renais de camundongos machos C57/Bl6, por 45 min. Após 4hs da lesão isquêmica, as CTMs IFNγR KO e CTMs controles foram administradas intraperitonealmente, e 24hs após a cirurgia os animais foram sacrificados. O tratamento com CTMs selvagens apresentou significativa redução dos níveis de uréia e creatinina sérica. No entanto, a redução desses níveis séricos com CTMs IFNγR KO foi menos intensa. Com relação à análise da resposta inflamatória do rim, os dados demonstram que a expressão de RNAm de IL-6 é maior nos animais tratados com CTMs IFNγR KO quando comparada ao tratamento com CTMs selvagens; porém, os dois tratamentos apresentam expressão reduzida em comparação aos animais não tratados. Já a expressão de RNAm de IL-10 é maior em animais tratados com CTMs em comparação aos não tratados... (Resumo completo, clicar acesso eletrônico abaixo)

A Doença Renal Crônica (DRC) é considerada um problema mundial de saúde pública. O paciente com DRC apresenta baixa tolerância ao exercício físico e como conseqüência apresenta limitações na capacidade funcional e força muscular respiratória. O paciente com DRC em programa de hemodiálise pode sofrer impactos negativos na sua capacidade funcional. Objetivo: Avaliar a capacidade funcional e a força muscular respiratória associada ao exercício físico em pacientes com doença renal crônica que realizam hemodiálise. Metodologia: 28 pacientes de ambos os sexos com idade entre 40 e 60 anos participaram do estudo, em programa de hemodiálise no Instituto do Rim da Santa Casa de Misericórdia de Presidente Prudente-SP. Os pacientes foram avaliados pela força muscular inspiratória (PImax) e força muscular expiratória (PEmax) pela manovacuometria e Teste de Caminhada de Seis Minutos (TC6’) para avaliar a capacidade funcional. Após as avaliações, os pacientes iniciaram o programa de atividade física, com duração de oito semanas, realizado 3 vezes por semana durante 40 minutos na hemodiálise. Ao final do programa de exercícios físicos, os pacientes foram reavaliados. Resultados: Na avaliação da força muscular respiratória o valor da PImax pós foi significativamente maior que o valor obtido na avaliação pré programa (p<0,05), para a variável PEmax não foi encontrada diferença significativa entre os momentos pré e pós intervenção (p<0,05). As avaliações da capacidade funcional ou Teste de Caminhada de Seis Minutos (TC6’) inicial e após o programa de exercícios, não apresentaram diferenças significativas (p<0,05). Dados da Escala de Borg indicaram redução significativa do cansaço e dispnéia (p<0,05), após o programa de exercícios. Os indicadores relativos à dor foram reduzidos, após o programa, em relação ao pré (p<0,05). Conclusão:... (Resumo completo, clicar acesso eletrônico abaixo)

It is known that exposure to substances in the environment can contribute to various reproductive disorders, especially if such exposure occurs during critical periods of development such as the intra-uterine and postnatal. The female reproductive system may be the target of androgens, both as a result of exposure to environmental chemicals, or by pathological conditions (polycystic ovary syndrome or congenital adrenal hyperplasia).Usually, little attention is given off in relation to the study of androgenic effects in the female reproductive axis. This study aims to evaluate the effects of exposure to androgens on the development, structure and reproductive function in rats whose mothers were exposed to testosterone propionate from gestational day 12 (DG12) after weaning - postnatal day 21 (DPN21) . For this purpose, pregnancy rats were divided into four groups: a control group that received corn oil (vehicle) and three groups receiving testosterone propionate in doses of 0.05 mg / kg / day, 0.1 mg / kg / day and 0.2 mg / kg / day, all under the same experimental conditions. The possible effects of exposure were assessed using reproductive parameters, such as a measure of anogenital distance, count areolas / nipples, age at vaginal opening and first estrus (puberty indicative installation), weight and histological evaluation of the reproductive organs ( uterus and ovaries), weight of the kidneys, liver and pituitary hormone levels, regularity of the estrous cycle, sexual behavior and fertility. Such analysis is important in understanding the effects of androgen exposure on the female genital system, especially on the reproductive potential, and processes that may involve morphofunctional changes. In these experimental conditions, it is concluded that treatment with PT caused reduction in body weight and initial masculinization in females without cubs, however, commit further sexual development

The aim of the present study was to analyze the etiology, type and treatment employed in the orbito-zygomatic fractures (OZ). Also, postoperative complications are described and correlated with the type of treatment used. Fifty patients with OZ fractures were evaluated. Orbital fractures in which the zygomatic bone was not involved were excluded. Epidemiologic data and characteristics of treatment such as the type of material used for osteosynthesis, number of anatomical sites on which rigid internal fixation (RIF) was applied, surgical approaches and associated complications were recorded. The main causes of trauma were motorcycle and bicycle accidents, constituting 52% of the sample. The osteosynthesis system used was the 2.0 mm, except in four patients in whom the 1.5mm system was used for fixation at the infra-orbital rim. A total of 18% of the patients required reconstruction of the internal orbit and in all cases titanium mesh was used. 46% of the patients received RIF in three anatomical sites, most in the fronto-zygomatic suture, infra-orbital rim and zygomatic-maxillary buttress. The most frequent complication was paresthesia of the infra-orbital nerve (34 patients, 68%). Other findings were also discussed with the intent of better understanding the treatment of the OZ fractures.

To evaluate the prevalence of hypertension and its correlation with the severity of renal injury and proteinuria in dogs with leishmaniosis, sixty-six dogs were divided into two groups. Group 1 (G1) was composed of 54 dogs included in stage 1 of chronic kidney disease (CKD), and group 2 (G2) of twelve dogs in stages 2 and 3 of CKD. Prevalence of hypertension was 28.8%, comprising 22.2% of the dogs from G1 and 58.3% from G2 (P=0.011). The mean arterial blood pressure (BP) of dogs from G1 (135.7 +/- 20.5) was lower than from G2 (170.0 +/- 26.3) (P <0.001). Urine proteincreatinine ratio (UP/C) revealed values above 0.5 in 75.7% of the dogs, with 34% presenting hypertension. All dogs with hypertension had histopathological and laboratory evidence of glomerular disease. Although there was no statistically significant correlation between elevated BP and the severity of glomerular lesions (P=0.408), there was a statistically significant correlation between elevated BP and increased UP/C in the studied population (P=0.002). Thus, dogs with leishmaniosis and renal disease must be screened for the presence of hypertension so that treatment may be instituted as early as possible, in countries where treatment is allowed, to prevent the progression of renal damage.

Streptococcosis is one of the major causes of mortality in tilapia's creation in Brazil, inducing great economic losses. As soon, the study objectived to determinate the frequency of isolation and identification the Streptococcus agalactiae in organs different of Oreochromis niloticus naturally infected, derived from eight fish farms in the northern region of the state of Parana, that presented clinical signs characteristics of streptococcal disease. However, blood samples and fragments (kidney, liver, spleen, heart and brain) were collected. These all samples were plated on solid medium of brain and heart infusion (BHI) added 5% ovine blood and incubated at 29 degrees C for 7 days in aerophilic conditions. Behind, the bacterial growth and from the macro and microscopic features, colonies compatibles with Streptococcus sp. gender, were selected. The species were identified by PCR reaction and confirmed by sequencing of 16S rDNA gene. The results exhibited that in tilapia of Nile infected with S. agalactiae the isolation is more common in brain, kidney and liver in descending order.

Annually hundreds of crab-eating foxes (Cerdocyon thous) are referred to rehabilitation centers and zoos in Brazil. The ultrasonographic study of wildlife species is an important tool for a non-invasive and accurate anatomical description and provides important information for wildlife veterinary care. The aim of the present study was to determine the characteristics of the main abdominal organs as well as the vascular indexes of the abdominal aorta and renal arteries of crab-eating foxes (Cerdocyon thous) using mode B ultrasonography and Doppler ultrasonography, respectively. Ultrasonographic features of the main abdominal organs were described and slight differences were noticed between ultrasound imaging of abdominal organs of crab-eating foxes and other species. The bladder presented wall thickness of 12 +/- 0.01 mm, with three defined layers. Both, the right and left kidneys presented corticomedullary ratio of 1: 1 and similarly to the adrenals and the liver, they were homogeneous and hypoechoic compared to the spleen. The spleen was homogeneous and hyperechoic compared to the kidneys. The stomach presented 3 to 5 peristaltic movements per minute, wall thickness of 39 +/- 0.05 mm and lumen and mucosa with hyperechoic and hypoechoic features, respectively. Small and large intestines presented 2 to 3 peristaltic movements per minute, wall thickness of 34 +/- 0.03 mm and three defined layers with hyperechogenic (submucosa and serosa) and hypoechogenic (muscular) features. Ovaries of the female crab-eating fox were hypoechoic compared to the spleen and with heterogeneous parenchyma due to the presence of 2x2 mm ovarian follicles. Prostates of the six males were regular and with a well defined boundary, with a homogeneous and hyperechoic parenchyma compared to the spleen. Vascular indexes of the abdominal aorta (PSV: 25.60 +/- 0.32 cm/s; EDV: 6.96 +/- 1.68cm/s; PI: 1.15 +/- 0.07 e RI: 0.73 +/- 0.07) and right (PSV: 23.08 +/- 3.34cm/s; EDV: 9.33 +/- 2.36cm/s; PI: 1.01 +/- 0.65 e RI: 0.65 +/- 0.16) and left renal arteries (PSV: 23.74 +/- 3.94cm/s; EDV: 9.07 +/- 3.02cm/s; PI: 1.04 +/- 0.31 e RI: 0.64 +/- 0.10) were determined. Thus, conventional and Doppler ultrasonographic imaging provides basic information that can be used as reference for the species as well for other wild canids and it is a precise and non-invasive method that can be safely used to evaluate and diagnose abdominal injuries in these patients.

A manutenção do balanço hídrico ou de água é particularmente desafiadora para os anfíbios em virtude de seu tegumento altamente permeável e o risco associado de perda evaporativa de água. Neste sentido, anuros terrestres exibem uma grande diversidade de mecanismos que atuam na diminuição da perda evaporativa de água e contribuem para a manutenção de um balanço hídrico adequado. Ademais, algumas espécies de anuros são conhecidas por tolerar altos níveis de desidratação e por engajar-se em atividades de rotina na natureza, ainda que sob níveis variáveis de desidratação. Finalmente, o próprio nível de desidratação pode acarretar alterações nos fatores envolvidos na manutenção do balanço de água dos anuros, aspecto muito pouco explorado em espécies terrestres neotropicais. Dessa forma, no presente estudo, mensuramos as taxas de perda evaporativa de água (PEA), reidratação a partir de água livre (Re) e calculamos a resistência da pele a desidratação (RP) em indivíduos adultos de Rhinella schneideri submetidos experimentalmente a diferentes níveis de desidratação (99%, 90%, 80% e 70% da massa corpórea inicial). Ademais, medimos as alterações causadas pela desidratação na osmolalidade plasmática (Osm), hematócrito (Htc), concentração de hemoglobina no sangue ([Hb]) e massa percentual dos órgãos viscerais. O objetivo central deste estudo foi avaliar os efeitos potenciais de diferentes níveis de desidratação sobre indicadores e repostas fisiológicas relevantes para a manutenção do balanço hídrico em uma espécie de anfíbio anuro terrestre. Nossos resultados mostram que quanto mais desidratados os animais, maiores a RP, a Re, a Osm, o Htc e a [Hb], e menores a PEA, e a massa percentual do fígado e do rim. O aumento da Osm, Htc e [Hb] indicam uma diminuição do compartimento aquoso do sangue, o que pode estar relacionado ao aumento da Re. A relação entre diminuição da PEA e aumento da...
