O inibidor de serino protease Antipaina preserva a integridade do acrossoma de espermatozoides bovino Curraleiro Pé-Duro durante a criopreservação / The inhibitor of serine protease Antipain preserve the integrity in the acrosome of sperm bovine Curraleiro Pé- Duro for cryopreservation

This study was conducted to evaluate the effect of different concentrations of inhibitor antipain serineprotease (10 g, 50 ug and 100 ug) in supplementing the dilutive of bovine semen freezing. Thirty-six ejaculatedfour Curraleiro Pé-Duro cattle were used for cryopreservation. The epifluorescence microscopy was used todetermine the acrosomal integrity and acrosome reaction rate was calculated after sperm were incubated for sixhours heparin. Spermatozoa cryopreserved in the presence of antipain significantly increased acrosomalintegrity, as they were able to complete the acrosome reaction in vitro. In conclusion, the inhibitor is antipainserine protease is able to preserve the integrity of cryopreserved sperm acrosomal cattle.(AU)

Histopatologia e Imunohistoquímica de testículos de cães naturalmente infectados por Leishmania sp / Histopathology and Immunohistochemistry testicles of dogs naturally infected by Leishmania sp

The objective of this study was to evaluate testicular changes and the presence of Leishmania sp. intesticles of dogs with Visceral Leishmaniasis (LV). The animals were obtained from Teresina Zoonosis ControlAdministration, and taken to the kennels of Agricultural Sciences Center of the Federal University of Piauí(UFPI), where they stayed for two months and were subsequently euthanized for removal of the testicles. 12 dogswere used, 06 positive (GI) and 06 negative (GII) for LV and conducted examinations of histopathology andimmunohistochemistry (IMH) of the testicles. All were negative by IMH technique and by histopathology. In thisstudy, we observed testicular lesions in all animals, with no direct relationship between the presence ofLeishmania sp. and intensity of the damage found in the reproductive system, reducing the possibility of venerealtransmission between oligositomatics dogs.(AU)

Estudo retrospectivo do otohematoma em cães atendidos em um hospital veterinário universitário / Retrospective aural hematoma in dogs presented to a University Veterinary Hospital

O otohematoma canino é um caso clínico comum na rotina da clínica médica de pequenos animais. Os principais fatores predisponentes correspondem a raça, sexo, idade, anatomia do pavilhão auricular e presença de outras afecções concomitantes. O presente trabalho objetivou a caracterização epidemiológica do hematoma auricular na espécie canina. Realizou-se um estudo retrospectivo utilizando os dados recolhidos das fichas clínicas de 55 cães com otohematoma, atendidos no Hospital Veterinário da Universidade Federal do Piauí, no período compreendido entre janeiro de 2007 a dezembro de 2008. O sexo masculino foi o mais acometido, com 62% dos casos. A faixa etária de maior representação variou de 7 a 8 anos de idade (29%). Os animais Sem Raça Definida possuíram destaque em relação à frequência de otoematoma (41%), seguindo-se dos indivíduos da raça Pastor Alemão (34%) e Fila Brasileiro (5%). A maioria dos pacientes apresentou um peso corporal superior a 20 Kg (71%). Os resultados obtidos sugeriram que o hematoma auricular canino apresentou alguns fatores de risco, como a idade adulta e o porte elevado do animal.

The otohematoma canine is a common clinical case in routine clinical care of small animals. The main predisposing factors correspond to race, sex, age, anatomy of the ear and the presence of other concomitant conditions. This study aimed to characterize the epidemiological auricular hematoma in dogs. We conducted a retrospective study using data collected from the medical records of 55 dogs with otohematoma treated at the Veterinary Hospital of the Federal University of Piauí, in the period from January 2007 to December 2008. The male was the most affected, with 62% of cases. The age group most represented ranged from 7 to 8 years of age (29%). The animals possessed undefined breed featured in the frequency of otohematoma (41%), followed by the German Shepherd individuals (34%) and Fila (5%). Most patients showed a body weight above 20 kg (71%). The results suggest that the canine auricular hematoma presented some risk factors, such as age and size large adult animal.
