E-mail: flavioribeiro@ufpi.edu.br The capuchin monkey is widespread both north and south of the Legal Amazon and in the Brazilian cerrado. Ten clinically healthy capuchin monkeys were submitted to an anatomical and radiographic study of their thoracic cavities. The radiographic evaluation allowed the description of biometric values associated with the cardiac silhouette and thoracic structures. Application of the VHS (vertebral heart size) method showed positive correlation (P<0.05) with depth of the thoracic cavity, as well as between the body length of vertebrae T3, T4, T5 and T6 and the cardiac length and width. The lung fields showed a diffuse interstitial pattern, more visible in the caudal lung lobes and a bronchial pattern in the middle and cranial lung lobes. The radiographic examination allowed preliminary inferences to be made concerning the syntopy of the thoracic structures and modification of the pulmonary patterns and cardiac anatomy for the capuchin monkey.

RESUMO.- Alves F.R., Costa F.B., Machado P.P., Diniz A.N., Araújo A.V.C., Ambrósio C.E. & Guerra P.C. 2012.

E-mail: flavioribeiro@ufpi.edu.br O macaco-prego é muito comum tanto no norte, quanto no sul da Amazônia Legal e no cerrado brasileiro. Dez macacos-prego clinicamente saudáveis foram submetidos a um estudo anatômico e radiográfico de suas cavidades torácicas. A avaliação radiográfica permitiu a descrição de valores biométricos associados à silhueta cardíaca e estruturas torácicas. A aplicação do método de VHS (vertebral heart size) demonstrou correlação positiva (P <0,05) com a profundidade da cavidade torácica, assim como entre o comprimento do corpo de vértebras T3, T4, T5 e T6 e do comprimento e largura cardíaca. Os campos pulmonares apresentaram padrão intersticial difuso, mais visível nos lobos pulmonares caudais e um padrão brônquial em lobo pulmonar médio e cranial. O exame radiográfico permitiu inferências preliminares a serem realizadas no âmbito da sintopia das estruturas torácicas e de modificação dos padrões pulmonares e anatomia cardíaca para o macaco-prego.

ABSTRACT.- Alves F.R., Costa F.B., Arouche M.M.S., Barros A.C.E., Miglino M.A., Vulcano L.C. & Guerra P.C. 2007. [Ultrasonographic evaluation of the urinary system, liver and uterus of Cebus apella monkey.] Avaliação ultra-sonográfica do sistema urinário, fígado e útero do macaco-prego, Cebus apella. Pesquisa Veterinária Brasileira 27(9):377-382. Departamento de Cirurgia, Faculdade de Medicina Veterinária e Zootecnia, Universidade de São Paulo, Av. Prof. Dr. Orlando Marques de Paiva 87, São Paulo, SP 05508-270, Brazil. E-mail: flaviovet@usp.br The Brown Capuchin, Cebus apella, has a wide distribution in the northern and southern Brazilian Amazon region and in the Cerrado (savanna). These monkeys are usually submitted to predatory chase, increasing the need for preservation of this wild animal species. An ultrasonographic examination of 10 Brown Capuchins was made in order to describe the normal ultrasonographic anatomy of their abdominal cavity. The urinary bladder revealed its wall thickness with an average of 0.2cm, the topographic situation of which allowed close relation with the wall of uterus and descendent colon. Using caudal abdominal scan, images of aorta, caudal vena cava and right iliac vein were obtained. Liver was accessible for examination by sagittal and cross-section ultrasound, allowing visualization of gallbladder and hepatic vessels. Renal scan allowed accuracy to evidence the echogenicity differences between pelvis, renal sinus, as well as the cortical-medullary relationship. The mean length of the kidneys was 6.24±0.31cm, and no significant differences were observed between left and right kidney length (Student’s t-test and ANOVA). The renal volume obtained was 2.37±0.18cm3. Correlation Coefficients of Pearson between right and left renal length and between right and left renal volume were r = 0.74 and 0.51. Mean thickness for cortical and medullar regions was 0.75±0.11 and 0.39±0.06cm, respectively. Correlation Coefficient of corticomedullar relation between right and left renal was r = 0.19. Examination by ultrasound was considered an efficient, non-invasive, fast and repeatable technique which provides useful data for clinicians and surgeons engaged in wild animal medicine.
