Uterine evaluation and gestation diagnosis in owl monkey (Aotus azarai infulatus) using the B mode ultrasound

Abstract

The chemical (use of tranquilizers) and husbandry factors (capture stress) may be related to the prenatal death. The establishing methods of conditioning the female to the ultrasonographic exam may offer a solution to this problem.

Ovarian and Uterine Ultrasonography in Aotus azarai infulatus

“…The results related to ultrasound uterine evaluation in owl monkeys are very similar to those reported in another study performed with the species (Monteiro et al 2006). However, several methodological particularities differentiate the 2 experiments: 1) We conducted our study without chemical restraint, allowing a prolonged monitoring, with a higher number of repetitions in time, favoring the subjects' conditioning to the ultrasound exam.…”

“…According to the literature, the uterine volume of human females undergoes alterations with age, number of parturitions, and hormonal influence (Mauad-Filho et al 2001). We observed only the effect of the number of parturitions, demonstrating that the uterine volume for owl monkeys is proportional to the number of parturitions, the same as reported in other studies (Mauad-Filho et al 2001;Monteiro et al 2006).…”

“…Only 1 examiner registered each uterine variable, 3 times, calculating the mean to obtain the uterine volume (UV). We performed this calculation by approximation using the 3 distances spheroidal geometric model (Monteiro et al 2006). We compared the dimensions and uterine volume to the number of parturitions, considering the female that never gave birth as nuliparous, only 1 parturition as primiparous, and ≥2 parturitions as multiparous.…”

Functional morphology of the tubular genital organs in the female owl monkey (Aotus spp.)

“…The results related to uterine evaluation in this study are very similar to those reported in previous studies performed with ultrasound in A. azarai infulatus . The simplex non‐pregnant uterus was characterized by a globular fundic portion and a small cervix that protruded into the vaginal canal, which is similar to other New World primate species , but different from apes, which have the fundic portion described as flattened .…”

Influência de diferentes protocolos de contenção nosvalores do eletrocardiograma de macacos-da-noite (Aotus azarae infulatus)

“…TZ: neste grupo foi utilizada a associação tiletamina e zolazepam, na dose de 5,5 mg.kg -1 pela via intramuscular; ISO: neste grupo foi utilizado o anestésico isoflurano, fornecido através de máscara facial, liberando-se o fluxo do anestésico associado ao oxigênio; CET: neste grupo foi utilizada associação de 15mg.kg -1 de cloridrato de cetamina e 1mg.kg -1 de midazolam, associados na mesma seringa pela via intramuscular; CF: neste grupo os animais foram contidos com o auxílio de luvas de raspa de couro, em posição supina, de forma semelhante ao descrito por Monteiro et al (2006).…”
