The aim of this study was to evaluate the viability of bull spermatozoa collected from the cauda epididymis stored at 18-20°C, which were compared with semen collected by electro-ejaculation method and preserved at 5°C. Ten pairs of testes from Tabapuã bulls were removed by orchiectomy and stored for 6 (G6), 12 (G12), 18 (G18), 24 (G24) and 30 (G30) h at room temperature (18-20°C). Seven days before orchiectomy, semen was collected by electro-ejaculation method. The sperm parameters evaluated were: sperm motility, vigor, concentration, morphology and acrosome defects. Sperm motility declined (p<0.05) when spermatozoa were stored for 30 h in the epididymis. The spermatozoa from the epididymis showed lower sperm motility than that of spermatozoa collected...

Hemangiopericytoma in a female dog with direct invasion of abdominal cavity and pulmonary metastasis Ciência Rural
Silva,Elisângela Olegário da; Romero,Fernanda; Green,Kerriel Thandile; Martins,Maria Isabel Mello; Bracarense,Ana Paula Frederico Rodrigues Loureiro.
An intact adult female Poodle dog was presented with a history of an increase in volume in the left and right mammary inguinal glands. The histopathological examination revealed a proliferation of spindle cells arranged in bundles with concentric arrangements surrounding blood vessels, occasionally collapsed. Three weeks after the surgery, the animal presented a recurrence of the tumor that extended from the left inguinal mammary gland to the vulva. Necropsy revealed direct invasion of the abdominal cavity by the tumor and pulmonary metastasis. The definitive diagnosis of hemangiopericytoma was made by histopathological and immunohistochemical examination. Pulmonary metastasis of CHP (canine hemangiopericytoma) is rare and there is no previous report of...
