BACKGROUND Knowing the physiological ranges of certain hematological and biochemical parameters is necessary for understanding the alterations caused by pathogenic agents and establishing differences between states of health and disease. Hematological evaluations and clinical chemistry were performed on livers and kidneys from owl monkeys with different(More)
BACKGROUND We aimed to evaluate the uterine and ovarian volumes of owl monkeys in different age groups with different numbers of live births and to analyze the interaction between both. METHODS We performed pelvic ultrasound exams to compare the uterine measurements with weight, age (infant, juvenile, subadult, young adults, and adults) and the number of(More)
BACKGROUND The studies on fecal steroid metabolites published with free-living primates are limited mainly by the difficulty in obtaining samples. METHODS A radioimmunoassay was used to measure the fecal steroid concentrations in Alouatta belzebul in the National Forest of Tapirape-Aquiri in Brazil. RESULTS AND CONCLUSIONS Androgens were significantly(More)
Clitoromegaly in the neonatal period is an important morphologic sign that can be useful for sexual determination in aberrant cases. In rhesus monkeys, differentiation of the external genitalia occurs early during gestation (at 55 to 60 d) and is complete by approximately 80 d. Most of the critical steps in genital differentiation in primates occur(More)
This study aimed to characterize anatomical and biochemical properties of owl monkey kidneys in order to provide normal reference values. Sixty-nine Aotus azarai infulatus (45 males and 24 females) were divided into four different age groups (AG1: 3 months-1 year; AG2: 2-3 years; AG3: 4-6 years; and AG4: over 7 years old). The monkeys were evaluated with a(More)
BACKGROUND Agnathia is a rare malformation characterized by the absence of the mandible. METHODS A male rhesus monkey with malformations was found dead and studied by internal examination, radiographs and histopathology. RESULTS A case of a rare first branchial arch anomaly with agenesis of the mandible and tongue is presented. The animal also had(More)
