Pregnancy and Medication Impact

This study aimed to characterize anatomical and biochemical properties of owl monkey kidneys in order to provide normal reference values. Sixty‐nine A otus azarai infulatus (45 males and 24 females) were divided into four different age groups ( AG 1: 3 months–1 year; AG 2: 2–3 years; AG 3: 4–6 years; and AG 4: over 7 years old). The monkeys were evaluated with a serum chemistry profile, focusing on serum creatinine ( SC r) and blood urea nitrogen ( BUN ) and with ultrasound. Mean body mass differed among the age groups. This significance was attributed to AG 1 body mass being significantly lower than in AG 2 and that in both AG 2 and AG 3 being significantly lower than in the two older age groups ( AG 3 and AG 4). SC r and BUN concentrations differed significantly between the sexes and SC r level correlated positively with age. In contrast, renal measurements did not differ between males and females. Left and right renal volumes did not differ significantly within age groups, or among AG 2, AG 3, and AG 4. Renal volumes in AG 1, however, while not differing from those in AG 2, did differ significantly from those in AG 3 and AG 4. In conclusion, this study provides ultrasonographic reference values for the morphology the kidneys in A . a. infulatus . Evidence is also provided that SC r and BUN levels in owl monkeys are influenced by the sex and age of the individual, factors that should be considered when interpreting test results. Am. J.
