A case of intersex occurrence in Steindachneridion parahybae (Steindachner, 1877) (Siluriformes: Pimelodidae) under captivity condition: a cytogenetic and morphological study Neotropical Ichthyology
Honji,Renato M.; Caneppele,Danilo; Pandolfi,Matias; Nostro,Fabiana L. Lo; Moreira,Renata G..
ABSTRACT Little is known about reproductive biology of endangered Steindachneridion parahybae , a gonochoristic teleost species inhabiting the Paraíba do Sul River Basin, and herein is the first description of intersex in S. parahybae juvenile. The normal appearance of ovaries and testes in juvenile from the same lot of breeding were also described for comparison, even as cytogenetic analysis was performed in these juveniles. One specimen was a priori classified as female due to the macroscopic characteristic of ovaries, with small yellow oocytes, without fringes (a main characteristic of catfish male), and larger than testes; however the microscopic analysis revealed the presence of ovotestes, including the complete spermatogenesis. S. parahybae had...

A comparative study of the ovaries in some Brazilian bees (Hymenoptera; Apoidea) Pap. Avulsos de Zool. (São Paulo)
Martins,Gustavo Ferreira; Serrão,José Eduardo.
The present paper concerns the morphological features of ovaries in 33 species of bees with different social behavior patterns. The ovaries of bees were examined under light microscope. They are polytrophic-meroistic ovaries formed for an anterior germarium and a basal vitellarium. The germarium houses the germ cells and in the vitellarium there are follicles arranged linearly. In general the follicle is constituted by a nutritive chamber (a cluster of nurse cells) and an oocyte chamber, both covered by a single epithelial layer of follicular cells. The number of ovarioles per ovary and the number of mature oocyte per ovary were analyzed. Measurements of ovariole length, oocyte size, oocyte width, follicular epithelial height and the intertegular distance...

A Potential Use of Color Ultrasound as a Tool for Reproductive Management: New Observations Using Color Ultrasound Scanning that were not Possible with Imaging Only in Black and White OAK
MIYAMOTO, Akio; SHIRASUNA, Koumei; HAYASHI, Ken-Go; KAMADA, Daichi; KAWASHIMA, Chiho; KANEKO, Etsushi; ACOSTA, Tomas J.; MATSUI, Motozumi; 宮本, 明夫; 白砂, 孔明; 川島, 千帆; 松井, 基純.
Ultrasonography (US) has been applied to the ovary and the uterus of domestic animals from the late 1980s, and established in 1990s as a practical tool for animal production. US made it possible to detect pregnancy at a very early stage and, most importantly, to observe the real-time dynamics of follicular development and hence the discovery of follicular waves. This has greatly contributed to our understanding of ovarian physiology and helped us to develop several "pin-point" protocols for hormonal treatment. While US may not seem to fit preconceived ideas of a "green" technology, it does not contravene environmental priorities, and it is non-invasive ("ethical") and non-hormonal ("clean"). Using the US technology that is now commercially available at a...

Acquired vesicovaginal fistula secondary to ovariohysterectomy in a bitch: a case report Arq. Bras. Med. Vet. Zootec.
Gadelha,C.R.F.; Ribeiro,A.P.C.; Apparício,M.F.; Covizzi,G.J.; Vicente,W.R.R..
A seven-year-old bitch was referred for investigation of a two-month history of strangury. Clinical signs had developed within two days of elective ovariohysterectomy. Ultrasonographic and radiographic examinations suggested stump pyometra or cervical granuloma and vesicovaginal fistula. Two laparotomies were performed to repair the adhesions, but no reduction in clinical signs was observed. Medical treatment was performed. Eight months later, the animal was admitted for examination and it appeared to be healthy but still had signs of strangury.

Association of recombinant bovine somatotropin (rBST) with equine chorionic gonadotropin (eCG) on antral follicle count and oocyte production in Holstein and Tabapuã heifers R. Bras. Zootec.
Morais,Hévea de; Spuri,Renata; Gonçalves,Tarcísio de Moraes; Carvalho,Rafaela Rodrigues de; Andrade,Renato Campos; Pinto,Tássia Louregiani Carvalho; Souza,José Camisão de.
The objective of this study was to investigate whether the use of rbST and eCG prior to ultrasound-guided follicular aspiration (OPU) improves oocyte yield and quality in Tabapuã and Holstein heifers. The study was conducted in two phases, 20 days apart, in a change-over design. The dominant follicle was ablated two days (D-2) before two treatments: stimulation (6 Holstein and 8 Tabapuã), 500 mg of rbST (Boostin®) on D0 and 500 IU of eCG (Folligon) on D2; and control (6 Holstein and 8 Tabapuã), in which heifers received injections of the excipient. Heifers were aspirated on D4. Oocytes were subjected to a well established commercial in vitro embryo production protocol (Vitrogen®) and embryos were evaluated seven days after fertilization. There was an...

Beneficial Effect of Hyperbaric Oxygen Therapy on the Follicular Survival in the Mouse Ovary after Transplantation OAK
HAYASHI, Satomi; ASANO, Tomoyoshi; KAKIZAKI, Ryujiro; SUZUKI, Hiroshi; 鈴木, 宏志.
A large proportion of follicles are lost during the initial ischemia that occurs after transplantation of ovarian tissues. Thus, the effect of hyperbaric oxygen therapy (HBO) on the follicular loss of ovarian tissues after transplantation was examined in mice. Ovarian slices from ICR mice were transplanted under the kidney capsule in ovariectomized ICR. Hyperbaric oxygen with 100% oxygen was initiated for 30 min at 2.5 atmospheres absolute immediately after transplantation, and this treatment was repeated at 48-h intervals for 2 weeks. The number of follicles was dramatically reduced at 2 weeks post transplantation. However, HBO was significantly effective in enhancing the survival of transplanted ovarian follicles. The survival rates of primordial and...

Characterization of blood flow and the effects of exogenous estradiol benzoate on residual follicles formed after ultrasound-guided transvaginal follicle aspiration in cattle. Repositório Alice
GHETTI, A. M.; SIQUEIRA, L. G. B.; ARASHIRO, E. K. N.; PALHÃO, M. P.; BRANDÃO, F. Z.; VIANA, J. H. M..
Abstract Background: Removal of the follicular content by ultrasound-guided transvaginal follicle aspiration (TVFA) may fail to induce immediate atresia and loss of function, resulting in the occurrence of residual follicles (RF). The aims of this study were to characterize the blood flow in RF and to determine the effects of the treatment with estradiol benzoate on RF fate. Lactating, cyclic Holstein-Gir crossbred cows were used. In Experiment 1, follicular wave emergence (D0) was synchronized in cows (n = 10) and follicular growth was then monitored by transrectal ultrasonography from D0 to D8, followed by TVFA of the largest follicle present on the ovaries 24 h later. Color Doppler ultrasound imaging was used to examine blood flow on the follicular...

Clinical and pathological presentation of squamous metaplasia of the rete ovarii in a Zebu cow Arq. Bras. Med. Vet. Zootec.
Borges,Á.M.; Peixoto,D.G.M.; Paixão,T.A.; Santos,R.L..
Squamous metaplasia of rete ovarii is characterized by replacement of the normal cuboidal epithelium of rete ovarii by a keratinized stratified scamous epithelium, leading to accumulation of keratinized material within the tubules and cystic dilatation of rete ovarii. The present study decribes a case of scamous metaplasia of rete ovarii in a 10 year old Zebu cow, including clinical, surgical, ultrasonographic, histopathological and hormonal findings. At first ultrasound examination the cow had lightly asymmetric ovaries with follicles presenting echogenicity similar to luteinized follicular cysts. After transvaginal follicular aspiration creamy yellowish sanguineous-purulent content was recovered. After unilateral ovariectomy the ovary was sectioned and...

Cystadenocarcinoma Arising from Ovary in a Three Year Old Doberman Bitch International Journal of Morphology
Ajadi,A. Temitope; Antia,E. Richard; Akang,E. Effiong.
A three- year- old Doberman was presented with complaint of lethargy and weight- loss. Physical examination revealed a mass in the right abdomen. Laboratory abnormalities included anaemia, azotaemia and metabolic acidosis. Sonogram of the mass was an anaechoic area surrounded by hypoechoic tissue. The mass was located between the right kidney and ovary and showed papillary and tubular pattern of cystadenocarcinoma. Nephroureterectomy and ovariohysterectomy was performed; however bitch was euthanized owing to poor improvement, while necropsy of the left kidney revealed an end-stage kidney. It was concluded that the cystadenocarcinoma must have arisen secondary to a primary ovarian adenocarcinoma through stromal invasion.

Desenvolvimento morfológico e dos ovários de Kalliapseudes schubarti Mañe-Garzon (Crustacea, Tanaidacea) do Canal de São Sebastião, São Paulo, Brasil Zoologia
Leite,Fosca Pedini Pereira; Leite,Paulo Eduardo Pereira.
The morphological stages of the Kalliapseudes schubarti Mañe-Garzon, 1949 females were easily determinated and they were similar, but the male stages show distint forms probably due to the ambient stimuli. The description of the male stages demonstrate that K. gianucai (Bacescu, 1979) is another male stage of K. schubarti, probably a secondary copulatory stage. The morphology and development of the ovary is related both with the maturity and with the morphological modifications of females stages.

Effect of Feed Restriction and Photoperiod on Reproduction and LEPR, MELR mRNA Expression of Layers Rev. Bras. Ciênc. Avic.
HAO,E; Chen,H; Ge,S; Huang,R.
ABSTRACT Photoperiod and nutrition are major factors that affect the reproductive efficiency particularly in female animals. In this study we examined the interaction of photoperiod and food restriction on growth, sexual maturation and receptor mRNA expressions of leptin, melatonin, and estrogen in abdominal fat and the ovary of pullets. There were no interaction effects between photoperiod and feeding level on body weight, abdominal fat weight, ovary weight at both 14 wk and 18 wk. Abdominal fat weight of feed restriction group was significantly lower compared with the control group at the age of 14 wk, 18 wk, and age of the first egg (AFE) (p<0.05). Ovary LEPR (Leptin receptor) gene expression showed an interaction effect of the first egg. Restricted...

Endocrine Integration of Fetal Ovaries Grafted under Kidney Capsule of Unilaterally or Bilaterally Orchidectomized Male Hamster International Journal of Morphology
Luna,S. L; Peña,S. I; Cuevas,A. J; Brown,D. I.
Mammalian ovary development undergoes important changes during the perinatal period, moment when follicles are assembled and start to develop in a process not well known, involving endocrine and paracrine factors. In order to investigate the effect of two different hormonal environments on the early development of the ovary, we used an autologous transplant model in which Syrian hamster fetal ovaries were grafted under the kidney capsule of males hosts previously unilaterally or bilaterally orchidectomized. After 35 days of graft, ovaries and kidney parenchyme of the host male did not present signs of rejection. Ovaries contained primordial, primary follicles, secondary follicles and few tertiary follicles with morphological features similar to ovaries of...
