Incidência de tumor venéreo transmissível em caninos

O Tumor venéreo transmissível, ou tumor de Sticker, é uma neoplasia de células redondas de origem incerta, na genitália externa de cães fêmeas e machos. Objetivou-se identificar a incidência do TVT, avaliando e observando a anamnese do animal afetado, o principal gênero afetado, raças, predisposição e sintomas. Houve maior ocorrência em fêmeas SRD, adultos em idade reprodutiva e cães não castrados. Técnicas diagnósticas foram efetivas, e o tratamento eletivo foi a base de quimioterapia com sulfato de vincristina, utilizando à cirurgia nos casos de excisão completa do tumor, devido menor custo e por ser mais acessível.

The transmissible venereal tumor or Sticker tumor is a neoplasm of round cells of uncertain origin, the external genitalia of female and male dogs. This study aimed to identify the incidence of TVT, evaluating and observing the history of the affected animal, the most affected gender, race, predisposition and symptoms. There was a higher occurrence in SRD females, adults of reproductive age and dogs neutered. Diagnostic techniques have been effective, and the elective treatment was chemotherapy based vincristine sulfate, using surgery in cases of complete tumor excision because of lower cost and be more accessible.

Deaths of Cows During Long Distance Transportation to the Slaughterhouse. Changes on Histopathological Examination, Muscle and Liver Glycogen Storage and Muscle pH

The present experiment aimed to perform histopathological, muscle and liver glycogen and muscle pH analyses ofcows dead during transportation, and submitted to necropsy in slaughterhouses inspected by Federal Agencies, in Araguaína– TO, Brazil, from January to July 2013. Six affected animals dead during transportation and submitted to necropsyconstituted the Experimental Group (EG); a Control Group (CG), was composed by 6 cows slaughtered ordinarily followingthe slaughter flow. Gross and histopathological evaluations were accomplished only on EG. The main gross lesionsobserved at necropsy were extensive subcutaneous and muscle hemorrhage and hematomas, interstitial (83.3% of cases) andalveolar (66.6% of cases) lung emphysema, lung congestion (66.6% of cases) and edema (16.6% of cases), kidney (83.3%of cases) and liver congestion (16.6% of cases). On histopathological evaluation, the lungs showed interstitial (100% ofcases) and alveolar emphysema (66.6% of cases), congestion (66.6% of cases), edema (16.6% of cases) and blood aspiration(16.6% of cases). Renal congestion (83.3% of cases), hyaline casts (50% of cases) and tubular degeneration were thekidneys changes (16.6% of cases). Rarefaction of the white pulp (66.6% of cases), red pulp (66.6% of cases) andhemosiderin (16.6% of cases) were detected on spleen. The hepatocytes showed turve and finely vacuolyzed cytoplasm(lace-like aspect) possibly caused by a reduction on glycogen (50% of cases) and congestion (16.6% of cases). Autholysiswas observed on 50% of the livers and 16.6% of the spleens and kidneys. The animals from the EG presented higher meanof degenerate muscle fibers. The intercostal muscle was more affected when compared with other muscles on the samegroup. Muscle pH values were higher on EG than on CG. Differently, glycogen average values were similar between groups(EG 58.97 µmol/g and CG 57.05 µmol/g)[...]
