Realizou-se anastomose cólon-trígono vesical em 12 cães adultos (cinco machos e sete fêmeas), sem raça definida e clinicamente normais. Todos os animais mantiveram a continência urinária imediatamente após a cirurgia. Amostras da região de transição cólon-trígono vesical foram colhidas aos 30 e 60 dias após a cirurgia para exames histopatológicos. Observou-se infiltrado inflamatório mononuclear na região de anastomose com invasão do epitélio de transição da bexiga sobre a mucosa do fragmento intestinal. A técnica mostrou-se simples e eficiente para a reparação da bexiga, com o cólon funcionando como substituto da bexiga, preservando as funções renal e vesical.

Tubulopapillary carcinoma of the mammary gland in a maned wolf (Chrysocyon brachyurus): histopathological and immunophenotypical analysis
Provedor de dados: 45
Autores: Gamba,C.O.; Damasceno,K.A.; Ferreira,E.; Malta,M.C.C.; Cassali,G.D.
A maned female wolf (Chrysocyon brachyurus) showed nodules in the inguinal and left abdominal cranial mammary glands. The mammary gland was surgically excised, and microscopic analysis revealed epithelial cell proliferation in a tubular and papillary pattern; delicate fibrovascular stalks presenting numerous layers of moderately pleomorfic epithelial cells were observed. This histologic appearance was compatible with a diagnosis of mammary tubulopapillary carcinoma. The immunohistochemical profile revealed nuclear positivity for estrogen (70%) and progesterone (at least 90% of the neoplastic cells). The myoepithelium-associated with neoplastic cells lacked integrity, as evidenced by failed smooth muscle alpha actin reactivity in microinvasive areas. A low...

Comparison of serum hormone levels of captive and free-living maned wolves Chrysocyon brachyurus
Provedor de dados: 56
Autores: Maia,O.B.; Jácomo,A.T.A.; Bringel,B.A.; Kashivakura,C.K.; Oliveira,C.A.; Teodoro,L.O.F.; Silveira,L.; Teixeira da Costa,M.E.L.; Malta,M.C.C.; Furtado,M.M.; Torres,N.M.; Mattos,P.S.R.; Viau,.P; Lima,T.F.G.; Morato,R.G.
Serum hormone levels were compared between captive and free-living maned wolves and seasonal variations of sex hormones were studied. Blood samples were collected from 16 male and 26 female adult animals from Brazilian zoos, and from 30 male and 24 female free-living adults to determine serum progesterone and testosterone by radioimmunoassay. Serum testosterone concentrations varied (P &lt; 0.05) across seasons for 16 captive males, being higher in autumn (2184.7 ± 355.1 pg/mL) than in summer (1080.7 ± 205.4 pg/mL), winter (1270.1 ± 276.6 pg/mL) and spring (963.9 ± 248.1 pg/mL), although they did not differ between summer, winter and spring. Testosterone concentration of 30 free-living males differed (P &lt; 0.05) between autumn (824.1 ± 512.2 pg/mL),...
