A new vision of the origin and the oocyte development in the Ostariophysi applied to Gymnotus sylvius (Teleostei: Gymnotiformes) Neotropical Ichthyology
França,Gisleine Fernanda; Grier,Harry J.; Quagio-Grassiotto,Irani.
Based on new knowledge coming from marine perciform species, the origin of oocytes and their development in the Ostariophysi, Gymnotus sylvius is described. In both Gymnotus sylvius and marine perciform fish, oogonia are found in the germinal epithelium that forms the surface of the ovarian lamellae. At the commencement of folliculogenesis, proliferation of oogonia and their entrance into meiosis gives rise to germ cell nests that extend into the stroma from the germinal epithelium. Both cell nests and the germinal epithelium are supported by the same basement membrane that separates them from the stroma. At the time of meiotic arrest, oocytes in a cell nest become separated one from the other as processes of prefollicle cells, these being derived from...

KOWSAR, Rasoul; JIEMTAWEEBOON, Sineenard; SHIRASUNA, Koumei; SHIMIZU, Takashi; SASAKI, Motoki; KITAMURA, Nobuo; MIYAMOTO, Akio; 清水, 隆; 佐々木, 基樹; 宮本, 明夫.
This study was to investigate the localization and distribution of eosinophils (EOS) in the bovine oviduct throughout the estrous cycle. Histological studies revealed more abundant EOS in the infundibula of the oviducts ipsilateral to the preovulatory dominant follicle and the ovulated ovary. The number of EOS was higher in the infundibula of the oviducts ipsilateral to the ovulated ovary than those of the oviducts contralateral to the ovulated ovary. The infundibula of the oviducts ipsilateral to the preovulatory dominant follicle had higher number of EOS than those of the oviducts ipsilateral to the mid-cycle corpus luteum. The number of EOS in the isthmus, but not in the ampulla, was higher in the outer layers (tunica muscularis and tunica serosa) than...

Although it induces synchronized ovulation, hCG reduces the fertility of Santa Ines ewes submitted to TAI Arq. Bras. Med. Vet. Zootec.
Dias,L.M.K.; Sales,J.N.S.; Viau,P.; Barros,M.B.P.; Nicolau,S.S.; Simões,L.M.S.; Alves,N.G.; Alonso,M.A.; Valentim,R.; Oliveira,C.A..
ABSTRACT The aim of this study was to evaluate hCG treatment on ovarian response and on pregnancy rate using a 9-day oestrus synchronization protocol in Santa Ines ewes. On a random oestrus cycle day, ewes received an intravaginal progesterone device (Primer-PR®, Tecnopec, Brazil). Nine days later (Day 9), 30µg of d-cloprostenol (Prolise®, Syntex, Argentina) and 250IU of eCG (Folligon®, Intervet, Brazil) were administered and the progesterone device was removed. This moment, the ewes were randomly assigned on two groups: Control Group and hCG Group. In the hCG Group, the ewes received 500IU of hCG (Vetecor®, Hertape-Calier, Spain) 24h after device removal. In the Control Group, the ewes did not receive any ovulation inductor. Control and hCG Groups ewes...

Artificial insemination system without estrous observation in suckled beef cows Ciência Rural
Borges,Luiz Felipe Kruel; Ferreira,Rogério; Siqueira,Lucas Carvalho; Bohrer,Rodrigo Camponogara; Borstmann,Jacson William; Oliveira,João Francisco Coelho de; Gonçalves,Paulo Bayard Dias.
The aim was to develop a timed artificial insemination (TAI) system in suckled beef cows. Cows (n=227), 60-80 days postpartum, received estradiol benzoate (5mg) and a vaginal device containing 250µg of medroxyprogesterone acetate (MPA; day 0). On day six, cloprostenol (125µg) and eCG (400IU) were administrated and calves were weaned for 88h. The devices were removed on day seven (BioRep group) or on day eight (TAI group). All cows of TAI group and cows of BioRep group that did not exhibit standing estrus received GnRH (100µg) on day 9. In experiment I, the follicular growth was monitored daily by transrectal ultrasound exams, from day 6 to day 9. The average size of the dominant follicle on day nine was 11.1±0.99mm (BioRep, n=7) and 11.5±0.65mm (TAI, n=7)...

Changes in the Messenger RNA Expressions of the Endothelin-1 and Angiotensin Systems in Mature Follicles of the Superovulated Bovine Ovary OAK
SHIMIZU, Takashi; BERISHA, Bajram; SCHAMS, Dieter; MIYAMOTO, Akio; 清水, 隆; 宮本, 明夫.
The aim of the present study was to examine the messenger RNA expressions of the endothelin and angiotensin systems during the periovulatory phase in gonadotrophin releasing hormone (GnRH)-treated cows. Ovaries were collected by transvaginal ovariectomy (n=5 cows/group), and the follicles (n=5, one follicle/cow) were classified into the following groups: before GnRH administration (control, before LH surge), 3-5 h after GnRH (during LH surge), 10 h after GnRH; 20 h after GnRH, 25 h after GnRH (peri-ovulation), and early corpus luteum (CL) (Days 2-3). Expression of mRNA was investigated using quantitative real-time PCR. The expression of angiotensin converting enzyme (ACE) mRNA significantly decreased immediately after onset of the LH surge and remained at...

Compte rendu des premières expérimentations de fécondation artificielle chez l'ombrine, Sciaenops ocellatus : études préliminaires de la maturation finale des ovocytes et de la qualité du sperme ArchiMer
Gardes, Lionel; Buchet, Vincent; Villanove, Philippe; Fauvel, Christian.
Artificial insemination mastery in red drum, Sciaenops ocellatus, requires a first experimental step wOOng at getting basic biological data. Regarding males, a relation between optical density of the solution (OD) measured by spectrophotometry and sperm concentration (SC) has been established : OD O,161*SC + 0,119. Mean sperm concentration measured is 4,36.10 10 spz.mL-1. This study shows an influence of the solution of dilution on spermatozoa motility and its evolution during short term preservation. As far as females are concemed, the follow-up of final maturation through the observation of samples taken during reguIar strippings, seems to he a good technique to limit overripening and spontaneous liheration of ovules. Some artificial insemination trials...

Does supplemental LH changes rate and time to ovulation and embryo yield in Santa Ines ewes treated for superovulation with FSH plus eCG? Ciência Rural
Oliveira,Maria Emilia Franco; Cordeiro,Mabel Freitas; Ferreira,Roberta Machado; Souza,Samuel Figueirêdo; Pieroni,Juliana Souza Pinto; Rodrigues,Luiz Fernando de Souza; Fonseca,Jeferson Ferreira da; Vicente,Wilter Ricardo Russiano.
The objective was to evaluate if supplemental LH given at the end of FSH treatment would synchronize the time of ovulation and increase the ovulation rate and embryo yield in Santa Ines ewes. Twenty superovulatory (SOV) programs were accomplished in cross-over design (60d interval). On D0, a CIDR device was inserted, and the device was replaced with a new one 7 days later, when 37.5µg of d-cloprostenol was administered. On D12, we started the SOV treatment, administering 256mg of pFSH 8 times, 12h apart. On D14, the CIDR was removed, and 200IU of eCG and 37.5µg of d-cloprostenol were administered. On D15, the ewes were allocated into one of two groups, a Control group (n=10) that received no supplemental LH and a LH group (n=10) treated with 7.5mg of LH...

Effects of a single use of the GnRH analog buserelin on the induction of ovulation and endocrine profiles in heavy draft mares OAK
MIKI, Wataru; ONIYAMA, Hiroyuki; TAKEDA, Naomasa; KIMURA, Yuki; HANEDA, Shingo; MATSUI, Motozumi; TAYA, Kazuyoshi; NAMBO, Yasuo.
We observed structural changes in the follicles and uterus of heavy draft mares during estrus and examined the effect of a single injection of the gonadotropin-releasing hormone analog buserelin on ovulation and endocrine profiles. Twenty-two heavy draft mares were divided into a buserelin-treated group (n=8) and a control group (n=14). Mares were given an intramuscular injection of 40 µg buserelin when they presented signs of estrus to a teaser stallion, had ≥45 mm diameter follicles, and presented decreased uterine edema compared with the previous examination. The follicles and uterus were monitored using transrectal ultrasound imaging and measurement of blood levels of luteinizing hormone (LH), follicle-stimulating hormone (FSH), progesterone, and...

Cavalcanti,Amanda dos Santos; Brandão,Felipe Zandonadi; Nogueira,Luiz Altamiro Garcia; Fonseca,Jeferson Ferreira da.
The objective of this study was to verify the effects of GnRH on ovulation and pregnancy of ewes subjected to a short-term synchronization of estrus. Santa Inês and crossbred Santa Inês/Dorper ewes received 60 mg MAP sponges during 6 days plus 300 IU eCG and 30 µg d-cloprostenol 24 h prior to sponge withdrawal (SW). Ewes were assigned to receive 0.9% NaCl solution (Tcontrol; n = 32) or 25 µg GnRH (licerelin, T GnRH; n = 34) 24 hours after SW. Each group was assigned to intrauterine insemination by laparoscopy (n = 25) or to natural mating (n = 41). Artificial insemination was performed with a single dose of fresh semen. For controlled mating, females were exposed to males 12, 24, 36 and 48 hours after SW. Ten females per treatment were subjected to...

O rebanho leiteiro do Acre é composto de animais de baixo padrão genético com índices produtivos diários em torno de 3 kg a 5 kg de leite por vaca, sendo alimentado exclusivamente a pasto. A genética inferior do rebanho e a baixa produtividade impedem que a pecuária leiteira acriana se destaque no cenário nacional. Grande parte do leite produzido no estado é oriunda de pequenas propriedades leiteiras. Para que esse segmento da pecuária tenha um bom desempenho, faz-se necessário adotar biotécnicas reprodutivas, visando introduzir espécies adaptadas aos trópicos, com a finalidade de formar a médio prazo um rebanho de leite de bom padrão genético. Esta publicação apresenta os resultados do protocolo hormonal nas sincronizações de ovulações para transferência...

In Vivo Evidence that Local Cortisol Production Increases in the Preovulatory Follicle of the Cow OAK
ACOSTA, Tomas J.; TETSUKA, Masa; MATSUI, Motozumi; SHIMIZU, Takashi; BERISHA, Bajram; SCHAMS, Dieter; MIYAMOTO, Akio; 松井, 基純; 清水, 隆; 宮本, 明夫.
The aim of the present in vivo study was to monitor real-time fluctuations of cortisol (Cr) in the wall of preovulatory follicles using a microdialysis system (MDS) implanted in the theca layer as well as changes in ovarian venous plasma (OVP) and jugular venous plasma (JVP). Seven cows were superovulated using FSH and prostaglandin F2α injections. Dialysis capillary membranes were surgically implanted into the theca layer of mature follicles and connected to a microdialysis system. Fractions of the perfusates were collected from Day -1 (Day 0=LH surge) to Day 3. No difference in the concentrations of Cr between JVP and OVP was detected throughout the experiment. Circulating concentrations of Cr ranged from 20 to 35 ng/ml 8 h after surgery in ovulatory and...

Induction of ovulation and stimulation of spermation by LHRH or an LHRH analog associated or not with pimozide. Effects on some teleost fish. ArchiMer
Billard, R; Weil, C; Barnabe, G.
Effectiveness of LHRH and one of its analogs (LHRH-A = D-Ala super(6) ethylamide) on induction of ovulation and stimulation of spermiation is reviewed here. LHRH was also combined with pimozide, an anti-dopaminergic agent, to try to cancel dopamine inhibition of gonatotropin (GtH) release. LHRH-A alone (50 mu g/kg) did not initiate ovulation but only oocyte maturation. When pimozide (10 mg/kg) and LHRH-A (50 mu g/kg) were combined, gonadotropic hormone secretion was significantly increased, causing ovulation and stimulating spermiation. This combination advanced ovulation in trout. Trout egg quality was markedly altered by the pimozide treatment; it remains to be tested in carp. In sea bass, LHRH-A was much more effective than LHRH, and ovulation was...

Induction of ovulation in quarter horse mares through the use of deslorelin acetate and human chorionic gonadotrophin (hCG) BABT
Figueiredo,Tatiana; Paiva,Roman; Kozicki,Luiz Ernandes; Kaercher,Fernanda; Weiss,Romildo Romualdo; Santos,Ivo Walter dos; Muradas,Priscilla Ricabone.
The aim this study was to compare two protocols of induction for ovulation by desloreline acetate and hCG in Quarter Horse mares. The choice of the animals was based on the observations by the estrus, by rectal palpation of the ovaries and by ultrassonography of the follicular dynamics. After estrus detection and follicle control, the measurement of the follicles and the classification of uterus were carried out. The animals that had dominant follicle (diameter more than 35 mm) and swollen uterus were used. In these conditions, the mares received hCG or desloreline acetate. Once ovulation occurred, the artificial insemination was carried. Two groups were performed: G1 (20 animals) received 1.5 mg desloreline acetate and G2 (20 animals) received 1700 IU of...

Neonatal handling induces anovulatory estrous cycles in rats BJMBR
Gomes,C.M.; Frantz,P.J.; Sanvitto,G.L.; Anselmo-Franci,J.A.; Lucion,A.B..
Since previous work has shown that stimulation early in life decreases sexual receptiveness as measured by the female lordosis quotient, we suggested that neonatal handling could affect the function of the hypothalamus-pituitary-gonadal axis. The effects of neonatal handling on the estrous cycle and ovulation were analyzed in adult rats. Two groups of animals were studied: intact (no manipulation, N = 10) and handled (N = 11). Pups were either handled daily for 1 min during the first 10 days of life or left undisturbed. At the age of 90 days, a vaginal smear was collected daily at 9:00 a.m. and analyzed for 29 days; at 9:00 a.m. on the day of estrus, animals were anesthetized with thiopental (40 mg/kg, ip), the ovaries were removed and the oviduct was...
