ABSTRACT
A cardiomiopatia dilatada é uma doença de caráter crônico, que compromete a função cardíaca, resultando em desequilíbrio da circulação sanguínea e da homeostase corporal do animal. Este relato apresenta a evolução do quadro clínico e o tratamento de cardiomiopatia dilatada em um exemplar cativo de tamanduá-bandeira. O animal apresentou quadro clínico de insuficiência cardíaca e foi submetido a duas baterias de exames laboratoriais e de imagem em um período de três meses. Posteriormente, foi iniciado o tratamento com pimobendan e suplementação de taurina, resultando em resposta positiva e melhora dos sinais clínicos do paciente. Os achados ecocardiográficos do caso foram compatíveis com cardiomiopatia dilatada com sinais evidentes de diminuição progressiva das frações de ejeção, bem como encurtamento e aumento expressivo das câmaras cardíacas, quando se comparou este caso ao de cães de grande porte e animais saudáveis da mesma espécie. O tratamento com inotrópico positivo, suplementação dietética de taurina e diuréticos se mostrou eficiente em controlar os sinais clínicos do animal.(AU)
The dilated cardiomyopathy it is a chronic disease that leads to a cardiac dysfunction, resulting in unstable blood circulation and specimen body homeostasis. This description shows the dilated cardiomyopathy evolution and treatment in a giant anteater captive model. The patient presented cardiac insufficient clinical condition and was submitted to two sets of laboratorial and image exams in three months. Furthermore, the treatment started with pimobendam and taurine supplementation, leading to satisfactory response to treatment and clinical improvement. The echocardiographic findings were compatible with dilated cardiomyopathy, moreover clear evidence of progressive reduction at the ejection portions and shortening and expressive increase of the cardiac chamber when compared to large dogs and healthy animals of the same species. Treatment with positive inotropic and taurine dietary supplement revealed as effective in clinical managementr.(AU)

Hematopoietic stem-cell transplantation (HSCT) is currently the only established curative treatment for sickle cell disease (SCD), but is limited by donor availability. Ethnicity is thought to have an impact on the complications experienced by patients that undergo HSCT and on the likelihood of identifying an human leukocyte antigen (HLA) matched donor. In the present study, we investigated the genomic ancestry and the distribution of HLA allele groups in Brazilian patients with SCD, compared these HLA profiles to worldwide populations and evaluate the availability of HLA-matched donors. A broad intercontinental admixture of patients with SCD was observed, with African ancestry ranging from 6.7% to 93.4%. In a dendrogram based on HLA frequencies, Brazilian patients with SCD were included in a branch containing only populations with a significant African component. Among the 126 patients evaluated, 10 (8%) found a HLA-matched unrelated donor in a database of 18 134 donors. Self-reported white, brown and black matched donors were identified, and no significant difference in the percentage of compatible donors was observed between these ethnic groups. Our results show that Brazilian patients with SCD are very admixed, indicating that this group is a promising target for admixture mapping of genes involved in complications after HSCT. Additional studies may help to clarify the impact of the genetic diversity and admixture of these patients on the donor availability.

Acupuncture derives from traditional Chinese medicine, which aims to restore homeostasis. The action mechanism of this technique involves stimulation of certain points on the skin by inserting a needle. The aim of this study was to evaluate the influence of stimulation of acupoints C7 and PC6 on the heart rate variability, heart rate and heart rhythm in healthy dogs. 30 male and female adult dogs were used, with no breed restriction. The animals were analyzed at two different times in weekly intervals. Firstly were applied needles in the true acupoints, and on the second time we applied needles in false acupoints. Previously to the acupuncture an ECG with 2 minutes of recorder was performed, and after an insertion of needles the electrocardiographic recording was maintained during the 30 minutes of acupuncture. Results showed no significant difference between the HR when comparing true and false acupoints (p = 0.890). For heart rate variability a small difference was observed between the groups (p = 0.0051), however, when comparing the baseline with 15 and 25 minutes of monitoring in the false acupoint group, no significant results were found when compared with true acupoint. In conclusion, it is suggested that the stimulation of acupoints C-7 and PC-6 in healthy dogs does not promote change in sympathovagal balance, specifically on the heart rate variability, heart rate and heart rhythm on healthy dogs.(AU)

The prevalence of hypocalcemia and hypomagnesemia was evaluated in horses with gastrointestinal diseases. For that, 12 animals were examined at the UVV Veterinary Hospital. Age and gender of the animals, as well breed clinical diagnosis, adopted therapy and outcomes were recorded. Serum determinations of total calcium and magnesium were done on the day of admission and during the period of hospitalization. They revealed the presence of low levels of calcium and magnesium. The comparison between survivals and non-survivals on the admission day had shown a significant result only for serum calcium.
ABSTRACT
Avaliaram-se os efeitos da furosemida sobre o lavado traqueal de eqüinos portadores de hemorragia pulmonar induzida pelo exercício (HPIE). Nove animais foram distribuídos em três grupos experimentais: grupo-controle, formado por três eqüinos hígidos e não portadores da doença; grupo 1, com três eqüinos portadores e não submetidos a tratamento; e grupo 2, com três eqüinos portadores da doença e tratados com furosemida na dose de 1mg/kg, quatro horas antes da atividade atlética. As amostras do lavado traqueal foram obtidas duas horas após o exercício físico e sua avaliação demonstrou que o uso do medicamento reduziu a severidade da HPIE, refletida pela redução no número relativo de hemossiderófagos (de 7,8 por cento no grupo 1 para 4,2 por cento no grupo 2) e no número de eritrócitos (de 77666 x 10³/ml no grupo 1 para 8000x10³/ml no grupo 2).
