Lymphoscintigraphy is the technique of choice for sentinel lymph node detection in women with early breast cancer, but there is limited information evaluating the value of this technique in animals. We investigated mammary lymphatic drainage in 25 young female mongrel dogs by intramammary injection of 18.5 MBq of 99mTc-dextran (70,000 Da). Lymph node anatomical referencing was obtained using an external marker, bone scintigraphy, or scintiscanning the body contour. Cranial and caudal thoracic mammary glands drained into the cranial sternal lymph node and axillary lymph center. The cranial thoracic mammary gland also drained into the superficial cervical lymph node in two of five animals. The cranial abdominal gland was drained by the axillary lymph center. The caudal abdominal mammary gland was drained by the superficial inguinal lymph node in all animals and simultaneously by medial iliac lymph nodes in four of five animals. In one dog, this mammary gland was also drained by the mediastinal and the superficial cervical lymph nodes. The inguinal mammary gland was drained by superficial inguinal lymph nodes and simultaneously via the medial iliac lymph node in one animal. Lymphatic communications between lymph nodes were identified in 11 of 25 (44%) animals. 99mTc-dextran mammary lymphoscintigraphy was easy and rapid to perform and may provide valuable information for further studies.

RESUMOA vascularização arterial do timo (número, origem e ordenação) bem como a distribuição parenquimal dos ramos penetrantes foram estudadas em 40 aves da linhagem Paraíso Pedrês. Trinta aves foram injetadas com látex e dissecadas, enquanto 10 aves tiveram seus sistemas arteriais injetados com resina (metil metacrilato e mercox) para a preparação de moldes vasculares. A principal fonte de irrigação encontrada foi a associação dos ramos oriundos das artérias comuns do nervo vago, tireóideas e ingluviais, sendo que seus ramos penetravam o parênquima dos lobos, principalmente pelas suas extremidades cranial e caudal. A partir da penetração, os ramos tímicos apresentavam distribuição predominante para a periferia do lobo, formando uma trama capilar poligonal, com espaços irregulares, característica de um órgão linforreticular.

The common marmoset is an important Neotropical primate for biomedical research. With the intention of providing pelvimetric values that allow the selection of animals with better characteristics for reproduction, we studied the X-ray of the pelvis, in ventro-dorsal projection of 12 adult animals, six males and six females, belonging to the National Center of Primates -CENP. The measurements were made to right diagonal diameters (RDD), left diagonal diameter (LDD), bi-iliac middle diameter (BIMD), bi-iliac upper diameter (BIUD), bi-iliac lower diameter (BILD), sacrum-pubic diameter (SPD), and the input area of the pelvis (IAP), which were compared in relation to sex and bodily correlated with the biometrics. The results of the means and standard deviations regarding pelvimetry (cm) were: for the RDD in males of 1.91±0.14 and in the females of 2.05±0.08; LDD in males of 1.85±0.16 and in females of 2.03± 0.08; BIMD in males of 1.46±0.12 and in the females of 1.5±0; BIUD showed in males 1.3±0.1 and in females of 1.3±0.06; BILD in males of 1.35±0.15 and in females of 1.25±0.08; SPD in males of 1.68±0.09 and in females of 1.93±0.13; IAP in males of 1.9±0.26 and in the females of 2.23±0.13. It was concluded that the pelvis of Callithrix jacchus could be classified as dolicopelvic type, there is sexual dimorphism in relation to the pelvis of adult animals and that the bodily measurements have low positive correlation with pelvic measurements.Keywords: radiology, pelvis, primates RESUMO O sagui-de-tufo-branco se destaca como um importante primata neotropical para as pesquisas biomédicas. Com o intuito de fornecer valores pelvimétricos que permitam a seleção de animais com melhores características para a reprodução, estudaram-se radiografias da pelve, em projeção ventrodorsal, de 12 animais, sendo seis machos e seis fêmeas, adultos, pertencentes ao Centro Nacional de Primatas -CENP. As mensurações realizadas foram referentes aos diâmetros diagonal direito (DDD), diagonal esquerdo (DDE), bi-ilíaco médio (DBIM), bi-ilíaco superior (DBIS), bi-ilíaco inferior (DBII), sacropúbico (DSP), além da área de entrada da pelve (AEP), os quais foram comparados em
