Abstract
ABSTRACT 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.

Abstract
A 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.
