Efeitos da acupuntura nos acupontos Shenmen (C-7) e Neiguan (PC-6) sobre a frequência cardíaca, a variabilidade da frequência cardíaca e o ritmo cardíaco em cães saudáveis / Effects of acupuncture at Shenmen (C-7) and Neiguan (PC-6) acupoints on the heart hate, heart rate variability and cardiac rhythm in healthy dogs

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)

Prevalência de hipocalcemia e hipomagnesemia em equinos com distúrbios gastrintestinais / Prevalence of hypocalcemia and hypomagnesemia in equines with gastrointestinal diseases

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.(AU)

Microbiological findings of tracheobronchial washes of healthy horses and those with respiratory diseases / Achados microbiológicos do lavado traqueobrônquico de equinos clinicamente sadios e daqueles portadores de afecções do sistema respiratório

This study evaluated the microbiological aspects of tracheobronchial washes obtained through tracheal puncture of 25 healthy horses and 65 horses with respiratory distress admitted to the Hospital Veterinario (HOVET, USP). In the control group, only 8 of the 25 animals did not present bacterial growth in the obtained samples. Furthermore, the group that included eight horses with bacterial bronchopneumonia (12.3% of the animals studied) presented bacterial growth in 100% of the samples, with special attention to Streptococcus alpha-hemolyticus. The technique proved to be efficient, but more research is needed to improve its use as a complementary exam on the diagnosis of equine respiratory disorders.

Foram avaliados os achados microbiológicos do lavado traqueobrônquico, obtido por coleta transtraqueal, de 65 equinos com sintomas de alteração do sistema respiratório e de 25 equinos assintomáticos (grupo controle) encaminhados ao HOVET - USP. No grupo controle somente oito dos 25 animais não apresentaram crescimento de patógenos nas amostras obtidas, enquanto que no grupo que incluiu oito equinos portadores de broncopneumonia bacteriana (12,3%dos animais estudados) houve crescimento em 100% das amostras, destacando-se Streptococcus alfa-hemolítico. A técnica mostrou-se eficiente, porém mais estudos precisam ser conduzidos tanto em equinos saudáveis como naqueles portadores de afecções do sistema respiratório com o propósito de aperfeiçoar o uso de tal exame complementar no diagnóstico definitivo de doenças respiratórias em equinos.

Evaluation of tracheal wash of horses with exercise-induced pulmonary hemorrhage treated with furosemide / Avaliação do lavado traqueal de eqüinos portadores de hemorragia pulmonar induzida pelo exercício tratados com furosemida

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).(AU)
