“…The changes in surface morphology of the ovary during follicular development in this species are similar to those changes reported for other primates, including macaques [10] and capuchin monkeys [11]. At 5-6 days after cloprostenol injection, 2-4 follicles were similar in surface diameter (1-1.5 mm); however, only 2-3 of these follicles proceeded to grow and subsequently ovulate.…”

“…Those investigators reported that of approximately 100 antral follicles, only 10% reached medium size (1.0-1.9 mm) and only 2-3 obtained a diameter greater than 2.0 mm by mid-follicular phase. Dierschke and Clark [6] reported identification of the ovulatory follicle 8 days before ovulation in macaques, while Nagle et al [11] reported identification of ovulatory follicles 4 days before ovulation in capuchin monkeys. There was only one wave of follicle growth in the present study; this pattern is similar to that observed in other primates but different from that for domestic species in which 2-3 waves of follicle growth may precede ovulation [15].…”

This paper describes the course of follicular development in vivo in the marmoset monkey, the only anthropoid primate with a relatively high (2-4) and variable ovulation number. Results are presented in relation to predictions from a mathematical model of control of follicle selection and ovulation number. Repeated laparoscopic examinations during the follicular phase were conducted for 14 cycles. Ovulatory follicles were 1.0 mm (median) in diameter at Day 6 and could be distinguished from nonovulatory follicles by Day 8, at which point they were 2.0 mm in diameter. Ovulations were not synchronous; the most common observation 1-2 days after the estradiol peak was ovulation of one follicle but not the other. Examination of the course of follicular development within a cycle and the distribution of ovulation sites both supported predictions stemming from a mathematical model of follicle selection developed by Lacker et al. [Biol Reprod 1987; 37:570-580]. Specific findings were the following: 1) Variations in patterns of follicle growth within a cycle resembled those generated by the model; in 64% of cycles, the 2-3 ovulatory follicles grew at similar rates. However, in 36% of cycles, ovulatory follicles displayed disparate rates of growth. 2) An examination of the distribution of ovulation sites (right versus left) revealed no significant difference from a binomial distribution, suggesting the likelihood that interovarian (rather than intraovarian) factors control this distribution.

“…In women, the preovulatory follicle can reach 20 mm (Baker & Wai, 1976). In C. apella, the mean diameter of the preovulatory follicle can reach 10-12 mm (Nagle et al, 1980). The 983 Fm is not the maximum diameter that an antral follicle can reach in C. apella females and this diameter does not correspond to the final reached at follicular maturation.…”

The present study aimed to obtain quanti-qualitative data about the follicular ovarian population in Cebus apella females. Seven ovaries were obtained from 4 C. apella adult females. The ovaries were subjected to light microscopy. The number of preantral and antral follicles for each ovary was estimated using the Fractionator method. The preantral follicles were classified into primordial, transitional, primary and secondary follicles. Antral follicles were those that presented an antral cavity. All counted follicles were classified as normal or degenerated. The diameter of the follicles, oocytes and their nuclei were determined to accompany the follicular development. All results were represented as mean ± SE. The number of preantral follicles was 56,938 ± 21,888 and 49,133 ± 26,896 for the right and left ovaries, respectively. The percentage of normal follicles was 80 ± 4.95%. The follicular diameter ranged from 22 ± 0.5 Fm to 61.2 ± 4.0 Fm. Regarding the antral follicles, the number of normal and degenerate follicles per ovary were 60.0 ± 19.0 and 3 ± 1.8 follicles, respectively. The antral follicular diameter was 514.4 + 56.6 Fm. In conclusion, the information obtained in this study can be used as a parameter for subsequent in vivo or in vitro studies about folliculogenesis in non-human neotropical primates of the C. apella species.

Pesq. Vet. Bras. 34(8):791-796, agosto 2014 791 RESUMO.-O objetivo desse trabalho foi contribuir com o estudo anatômico, morfométrico, ultraestrutural e propriedades físicas dos dentes permanentes do primata Sapajus apella. Para tal, foram utilizados 10 animais adultos e machos. Os dentes foram avaliados quanto ao seu comprimento e quanto à anatomia radicular externa e interna considerando número de raízes e canais, forma e direção radicular e forma do canal, assim como análise da densidade e diâmetro tubular do canal radicular, composição e microdureza dentinária. A anatomia radicular desse primata apresentou especificidades, como o número de raízes do segundo pré-molar superior e a presença do terceiro pré--molar. Quanto à densidade e o diâmetro dos túbulos dentinários, observou-se uma diminuição do número e diâmetro de túbulos ao longo do canal radicular, havendo diferença estatisticamente significante ao se comparar o terço apical com as regiões cervical e média, padrão de densidade e tamanho semelhantes a dentes humanos. Semelhanças também foram encontradas com dentes humanos quando comparados os valores de microdureza e proporção de elementos químicos encontrados na dentina radicular. Brazil. E-mail: rafalima@ufpa.br This paper aimed the anatomical study including morphometric, ultrastructural and physical properties of permanent teeth of Sapajus apella primate. Ten adult male monkeys were studied. The teeth were evaluated for their length, root anatomy (external and internal considering the number of roots and canals), direction and shape of the root canal, density and diameter of the tubular root canal, dentin microhardness, and composition. The root anatomy showed specificity regarding the number of roots of the second premolar and the presence of the third premolar. We observed a decrease in the number and diameter of dentinal tubules along the root canal, a statistically significant difference when compared with the apical and cervical regions. Similarities with human teeth were found in regard to microhardness values and proportion of chemical elements in the root dentin.
