Analysis of EGFR and HER-2 expressions in ductal carcinomas in situ in canine mammary glands Arq. Bras. Med. Vet. Zootec.
Silva,I.L.D.; Dias,A.P.M.; Bertagnolli,A.C.; Cassali,G.D.; Ferreira,E..
Biomolecular evidence has shown that ductal carcinoma in situ(DCIS) may develop into invasive carcinoma of the canine mammary gland, and mutations in proto-oncogenes HER2 and EGFR; two members of the family of epidermal growth factor receptors, may be involved in this process. The purpose of this study was the characterization of the immunohistochemical expression of the EGFR and HER2 proteins in the process of neoplastic transformation, supposedly present in ductal carcinomas in situin canine mammary glands. Fifteen cases of DCIS were evaluated, with a higher expression of HER2 and EGFR being observed in low-grade carcinomas when compared with high-grade neoplasms, and with a high positive statistical correlation in the latter. Results suggest that...

Aortic body tumors in dogs from Northern Paraná, Brazil Ciência Rural
Headley,Selwyn Arlington; Bracarense,Ana Paula; Nakagawa,Tizianne; Moreno,Kleber; Pereira,Patrícia Mendes; Reis,Antônio Carlos Faria dos.
This article describes the occurrence of aortic body tumors in four dogs from Southern Brazil. All dogs were males, more than 9 year of age; most of these were from the Boxer breed of dogs. The animals had large neoplastic growths at the base of the heart, which demonstrated histologic characteristics consistent with that of aortic body tumor. By immunohistochemistry, tissue sections from all dogs reacted positively to neuron specific enolase. These cases might represent the first description of this tumor in dogs from Brazil, as confirmed by immunohistochemistry.

Aorticopulmonary septal defect in a dog: case report Arq. Bras. Med. Vet. Zootec.
Pascon,J.P.E.; Ondani,A.C.; Junior,D.P.; Andrade,J.N.M.; Camacho,A.A..
A 10-month-old intact female mixed breed dog was referred for evaluation of exercise-induced dyspnea and a low grade II/VI systolic murmur was detected. The communication between ascending aortic and pulmonary trunk was observed by detecting a continuous flow just above the semilunar valves on echoDopplercardiography and attested by surgery. After the surgical procedure, the dog was presented in good clinical conditions without exercise-induced dyspnea, reflecting the importance of an early and accurate diagnostic for the therapeutic success. This is the first Brazilian report of this rare congenital disease and the unique well succeed surgery in the veterinary literature.
