Survey of veterinary practitioners about their experiences with urinary disorders in dogs and cats

Selected veterinarians were surveyed about their recalled experiences of urinary disorders, especially renal conditions, in current practice. When contacted by phone, 114 veterinarians in four states agreed to participate and 100 of them returned completed questionnaires. The three conditions of most concern nominated by 114 practitioners related to skin, endocrine and gastrointestinal systems (mentioned by 65, 35 and 32%, respectively), followed by urinary, cardiac and respiratory disorders (23, 20, 17%). From the questionnaire, the two body systems most often noted as abnormal in unwell dogs and cats were skin/eyes/ears and alimentary; urinary was third in cats and fifth in dogs. The urinary disorders reported as mast common were bacterial cystitis in dogs and nonobstructed haematuria/dysuria in cats. The frequency of diagnosing renal failure in dogs and cats was mostly "one case per two weeks" (43%), with "one or more per week" (28%) or "one per month" (22%) the main alternatives. Methods used to diagnose or investigate renal disease were generally blood biochemical tests, haematology and urinalysis, but imaging techniques were also popular. Most favoured treatments for chronic renal failure were intravenous fluids, multivitamins, anabolic steroids, and commercial. renal diets. Antimicrobials were often used, but phosphate binders, vitamin D analogues and erythropoietin were rarely employed

Estudo eletrocardiográfico de equinos de salto sadios

Avaliou-se o eletrocardiograma de 100 equinos sadios praticantes de hipismo clássico modalidade salto, com idades entre 4 e 19 anos, sendo 61 machos e 39 fêmeas, com média de 516,3 kg. Observou-se frequência cardíaca média de 40,20 ±13,33 bpm, sendo o ritmo cardíaco mais freqüente o sinusal (56%). As alterações de ritmo cardíaco estiveram presentes em 38% dos animais estudados, sendo a mais presente o marcapasso migratório (22%), seguido de bloqueio atrioventricular de 2º grau (4%), bloqueio atrioventricular de 1º grau (3%), contração ventricular prematura (2%), contração atrial prematura (1%). Não se observou correlação entre as variáveis estudadas (freqüência cardíaca, ritmo e arritmias) e a capacidade atlética, a idade e o sexo. O escore cardíaco após analise estatística não diferiu entre os grupos quanto ao desempenho atlético, a faixa etária e o sexo. O escore cardíaco, nesta amostra, não se mostrou um parâmetro confiável para se predizer o futuro atlético ou o nível de treinamento do eqüino

Search for particles with unexpected mass and charge in Z decays

During 1989 and 1990 over 180 000 hadronic and leptonic events, corresponding to 8 pb−1 of luminosity, were collected by the ALEPH detector in a scan of the Z peak at the e+e− collider LEP. This letter reports the results of a search in these data for particles with unexpected mass and charge by measurement of the ionization energy loss of charged tracks in the ALEPH TPC central tracking detector. The mass limits for the pair production of fractionally charged particles and of heavy, long lived charged particles are extended to 43 GeV/c2 at 90% confidence level. If single production of a heavy particle is considered, the mass limit is extended to more than 70 GeV/c2
