ABSTRACT

Following the induction of oestrus out of season in small ruminants, low fertility and variations in fertility rates are associated with embryonic losses. One of the main causes of embryonic loss is luteal dysfunction. Gonadotropin Releasing Hormone (GnRH) supports the luteal structure, and increasing progesterone levels may be beneficial in terms of promoting embryonic life. The main objective of the present study was to evaluate the efficacy of GnRH administration following an oestrus induction protocol in the anoestrus season for preventing embryonic loss in goats having failure to conceive during the season. In the study, 106 Damascus goats aged 3-5 years and weighing 45-60 kg were used. The oestrus of 106 goats in the anoestrous group was stimulated with progesterone and pregnant mare serum gonadotropin (PMSG) treatment. Out of breeding season, goats were divided into the 4 following groups: GnRH0 (n = 27), GnRH7 (n = 26), GnRH0+7 (n = 27) and control (n = 26). In each goat, an intravaginal sponge (IS) containing 20 mg of fluorogestone acetate (FGA) was placed into the vagina and left for 9 days. With the withdrawal of the sponge, 550IU PMSG and 125 µg of d-cloprostenol were injected intramuscularly. Oestrus detection was made via teaser bucks for 3 days starting 24 h after withdrawal of the IS. Eighteen bucks known to be fertile were used for breeding. Goats in the oestrus period were mated via natural breeding. The GnRH analogue lecirelin was injected intramuscularly at breeding in the GnRH0 group, on day 7 post-breeding in the GnRH7 group, and both at breeding and on day 7 post-breeding in the GnRH0+7 group. No injections were given to the control group. Blood samples for progesterone measurement were taken by jugular vena puncturing on days 3, 6, 7, 10, 13, 16, and 19 after breeding from 10 randomly chosen goats in all groups. The goats with a level of > 3.5 ng/mL of progesterone on day 21 post-breeding were evaluated as pregnant. Pregnancy was also viewed on day 50 after breeding by real-time ultrasonography (USG) with a 5-7.5 MHz convex probe. The oestrus rate was 96.23% (102/106) in the goats. The rates of onset of oestrus between 36-48 h, 48-60 h and 60 h and beyond were 38.7% (41/106), 21.7% (23/106) and 35.8% (38/106), respectively. The total pregnancy rate was 35.8% (38/106). There were no statistically significant differences (P > 0.05) found for the pregnancy rate, embryonic death rate or progesterone concentration of the groups. However, serum progesterone levels were statistically different in the GnRH7 group compared with the control group (P < 0.05). After synchronisation, various anti-luteolytic strategies can be used to support corpus luteum development and elevate progesterone concentration in the luteal phase to decrease embryonic loss and increase reproductive performance. Therefore, application of GnRH to support the luteal structure and to increase progesterone levels may be beneficial in terms of supporting embryonic life. The results showed that GnRH treatment on the day 7 post-breeding following oestrus induction, including FGA and PMSG, can increase serum progesterone levels in Damascus goats in the anoestrus period. However, following oestrus induction in the anoestrus period, it was seen that GnRH treatment at breeding or on day 7 after breeding did not have any positive effect on embryonic loss or reproductive performance. In conclusion, it was considered that this protocol could be implemented successfully, yielding a 35% pregnancy rate in Damascus goats in the anoestrus period, but embryonic loss must be deeply studied in detail.(AU)

ABSTRACT

Determining if reproductive failures in ewes at the semiarid region in the state of Bahia are related to the consumption of the species Cenostigma pyramidale (Tul.) Gagnon & G.P. Lewis, and this study was developed using pregnant ewes divided into six groups: G1, G2, G3, G4 with six animals each, G5 and G6 with ten animals. Each group received fence leaves in the proportion of 1%, 2%, 0.5%, and 0.25% of live weight (LW) respectively; G5 and G6, with ten animals each, receiving 0.25% and 0.5% of the LW, respectively, and the Control Group, comprising 16 ewes, were grass feeding (Cynodon dactylon). Ewes from G1 to G4 were the same, except for two, and started ingestion of the plant four days after ending of natural mating on the 80th day of gestation, while those regarding from G5 to G6 groups started ingestion on the 26th day of gestation ending on the 98 day. The ultrasonographic test was performed weekly. In G1 ewes (1%), there was an embryonic loss on the 32nd and 39th days of gestation and abortion on the 46th day. In G2 (2%), the embryo loss was earlier (on the 26th day of gestation), and abortion on the 46th day of gestation. In G3 group (0.5%), there was an embryonic loss around the 40th day of gestation. In G4 group (0.25%), it was observed the occurrence of one death lamb with bone malformations. In G6 (0.5%), abortion occurred later (108 days), followed by retained placenta. This was also verified in G5 group (0.25%). The presence of fetal malformation was found in death lambs born in G4 group, born alive from G5 and G6 groups, and one aborted from G6. In G5 and G6 groups, there were also genetic alterations on surviving lambs. In addition to these results, recurrent estrus was observed without gestation in G1, G2, G3, and G4 ewes. From the Control Group, 13 normal lambs were born without genetic alterations; furthermore, concerning a quadruple birth, three lambs were born dead. The results infer that species of C. pyramidale in low doses causes reproductive losses in pregnant ewes, therefore it is not recommended for sheep diet over the first 60 days of gestation.(AU)


Para determinar se falhas reprodutivas em ovelhas na região semiárida da Bahia estão relacionadas ao consumo de Cenostigma pyramidale (Tul.) Gagnon & G.P. Lewis, foi realizado um estudo utilizando-se ovelhas prenhes divididas em seis grupos e dois Grupos Controle. Os grupos G1, G2, G3 e G4 com seis animais cada. Cada grupo recebeu folhas fenadas na proporção de 1%, 2%, 0,5% e 0,25% do peso vivo (PV) respectivamente; G5 e G6, com 10 animais cada, que receberam 0,25% e 0,5% do PV respectivamente. Os Grupos Controle foram alimentados com ração e capim (Cynodon dactylon). Ovelhas dos grupos 1 a 4 iniciaram ingestão da planta quatro dias após monta natural com término aos 80 dias de gestação, enquanto as dos grupos 5 a 6 iniciaram ingestão no 26º dia de gestação com término aos 98 dias. Avaliação ultrassonográfica foi realizada semanalmente. Nos animais do G1 (1%), verificou-se perda embrionária aos 32 e 39 dias de gestação, e aborto aos 46 dias. Nos do G2 (2%) a perda embrionária foi mais precoce (26 dias), e aborto aos 46 dias. No G3 (0,5%), houve perda embrionária em torno dos 40 dias. No G4 (0,25%), verificou-se ocorrência de natimorto com malformações aos 150 dias de gestação. No G6 (0,5%) o aborto ocorreu mais tardiamente (108 dias), seguido de retenção de placenta. Essa ocorrência também foi verificada no G5 (0,25%). A presença de malformação fetal foi encontrada em fetos natimorto do G4, nascidos vivos do G5 e G6, e um abortado do G6. No G5 e G6 também foram observadas alterações de aprumos em cordeiros sobreviventes. Do Grupo Controle nasceram 13 borregos normais, porém uma ovelha apresentou gestação quádrupla com três natimortos. Os resultados inferem que C. pyramidale fenada em baixas doses causa perdas reprodutivas em ovelhas gestantes, não sendo por isso recomendada para a dieta de ovelhas durante os primeiros 60 dias de gestação.(AU)

ABSTRACT

<p><b>OBJECTIVES</b>To investigate the clinical effect of sequential therapeutic intervention Yupei Qisun [compensating for weakness by invigorating Kidney (Shen) and Spleen (Pi) in advance] in Chinese medicine (CM) and hysteroscopic endometrial mechanical stimulation on the treatment of infertile patients with repeated implantation failure (RIF); and to study the differences in patients' endometrial thickness and type on the day of embryo transfer, serum hormone levels on embryo transfer day and clinical pregnancy outcomes.</p><p><b>METHODS</b>In the clinical study, 168 frozen-thawed embryo transfer (FET) cycles for couples with RIF conforming to the research protocol were randomly divided into three groups: a CM group with 56 cycles (CM combined with FET), a hysteroscopy group with 55 cycles (hysteroscopic endometrial mechanical stimulation), and a control group with 57 cycles (conventional FET). Differences in endometrial thickness on the embryo transfer day, levels of serum estradiol (E2) and progesterone (P) on the embryo transfer day, the E2/P ratio on the embryo transfer day, biochemical and clinical pregnancy rates, implantation rate, abnormal pregnancy rate and other indices were compared among the three groups.</p><p><b>RESULTS</b>Endometrial thickness, E2 and P levels, and the E2/P ratio on embryo transfer day and other factors had no significant differences among groups. The biochemical pregnancy, clinical pregnancy, and implantation rates of the CM and hysteroscopy groups were significantly higher than the control group (P<0.05), and there were no significant differences between these two groups. The abnormal pregnancy rate had no significant difference among the three groups.</p><p><b>CONCLUSIONS</b>Sequential therapy of Yupei Qisun could significantly improve the clinical outcomes of rif-fet cycles, being equivalent to hysteroscopic endometrial mechanical stimulation, and provided a reliable method to treat such infertile couples.</p>

ABSTRACT

Estudou-se o efeito da idade sobre a fertilidade de éguas inseminadas com sêmen asinino diluído, resfriado e armazenado. Os ciclos foram acompanhados por palpação transretal e rufiação, sendo as inseminações realizadas às terças, quintas e sábados, a partir da detecção de um folículo de 3,0 a 3,5cm de diâmetro, em um dos ovários, até a ovulação. O sêmen de cinco jumentos da raça Pêga foi diluído nos diluidores de leite em pó desnatado-glicose ou glicina-gema de ovo, resfriado a 5ºC e armazenado por 12 horas, sendo a dose inseminante de 400 x 106 espermatozoides móveis (no momento da diluição final, pré-resfriamento). Os resultados de 195 ciclos estrais, referentes a 141 éguas, foram agrupados em classes, de acordo com a idade das éguas: 2,5 a 6 anos, 6,5 a 10 anos, 10,5 a 14 anos e 14,5 a 19 anos. As taxas de concepção, ao primeiro ciclo, foram de 68,42%, 50,75%, 46,88% e 52,17% e, após quatro ciclos, de 69,57%, 47,92%, 46,34% e 45,71% para as faixas etárias de 2,5 a 6, 6,5 a 10, 10,5 a 14 e 14,5 a 19 anos, respectivamente (P>0,05). A idade não teve efeito sobre a fertilidade das éguas inseminadas com sêmen asinino diluído e resfriado...


The effect of the mare age on fertility of mares inseminated with diluted, cooled and stored jackass semen was studied. The females were controlled by transrectal palpation and teasing, and inseminated every Tuesday, Thursday and Saturday, since the detection of a 3.0 to 3.5cm follicle diameter, in one of the ovaries, until ovulation. The semen of five Pêga jackasses was diluted in skim milk-glucose or in egg yolk-glicine extender and cooled at 5ºC for 12 hours, with the inseminate dose of 400 x 106 motile spermatozoa (at the moment of the final dilution, before cooling). The results of 195 cycles of 141 mares were grouped, in accordance with the age: 2.5 to 6 years, 6.5 to 10 years, 10.5 to 14 years and 14.5 to 19 years. The pregnancy rates for the first cycle were 68.42%, 50.75%, 46.88% and 52.17%, and after four cycles, the pregnancy rates/cycle were 69.57%, 47.92%, 46.34% and 45.71%, respectively for 2.5 to 6, 6.5 to 10, 10.5 to 14 and 14.5 to 19 years (P>0,05). The mare age had no influence on fertility, using diluted and cooled jackass semen...

ABSTRACT

Citrinin is the one of the well-known mycotoxins, which is possibly spread all over the world. The graded doses of citrinin (1, 3 and 5 ppm CIT in feed) in female Wistar rats 10 weeks prior to mating, during mating and during organogenesis resulted in resorptions and post implantation losses, decreased fetal body weights and crown-rump lengths in fetuses of all groups. Various developmental anomalies recorded in fetuses of treated rats included gross (wrist drop, curled tail, stretched forelimb, subcutaneous haematoma), skeletal (incomplete ossification of skull bones, incomplete fusion of vertebral bodies, complete and partial agenesis of sternaebrae, metacarpals, metatarsals and phalanges, fused ribs and swing out ribs) and visceral (internal and external hydrocephalus, cerebellar hypoplasia, microphthalmia, roundening of heart, contracted kidneys, dilated renal pelvis and cryptorchid testes). The results suggest that CIT has adverse effects on fetal development which may be due to the longer bioavailability of citrinin in the animals.

ABSTRACT

<p><b>OBJECTIVE</b>To investigate chromosomal euploidies in early-stage arrested human embryos.</p><p><b>METHODS</b>To determine the euploidy status of the 24 chromosomes, 13 embryos were analyzed, which included 5 arrested at 4-cell stage, 4 arrested at 8-cell stage, and 4 embryos at blastocyst stage regardless of their morphological scores. All embryos were subjected to biopsy, whole genome amplification, and array comparative genome hybridization analysis.</p><p><b>RESULTS</b>Chromosome euploidies of the arrested embryos can be normal, aberrant and chaotic. Mosaicism is prevalent in early stage cleavage, whilst most of the blastocysts, even with poor morphology, are normal diploid.</p><p><b>CONCLUSION</b>Arrested embryo may have normal chromosomes euploidy. Mosaicism is common in cleavage stage embryos. Early stage embryo arrest may not be solely attributable to chromosomal aneuploidies and needs further research.</p>

ABSTRACT

A endometrite crônica é um processo inflamatório persistente na camada endometrial, geralmente causada por invasão bacteriana. É uma afecção mal definida quanto a critérios de diagnósticos e tratamento. Devido à sua discreta sintomatologia, a real prevalência da endometrite crônica na população em geral não é conhecida, mas estima-se que esteja entre 0,8 e 19%. A aplicação de protocolos para rastreamento da endometrite crônica em mulheres com falha de implantação de embriões de boa qualidade após fertilização in vitro FIV é controversa. Alguns serviços utilizam a histeroscopia em todas as pacientes antes de iniciar o tratamento de reprodução assistida; entretanto, não há consenso de que a efetividade da histeroscopia melhore o prognóstico das mulheres inférteis. Os achados sugerem que o impacto da endometrite crônica na fertilidade e nos resultados da FIV precisam de futuras investigações em estudos prospectivos randomizados.


Chronic endometritis is a persistent inflammation of the endometrial lining usually caused by bacteria invasion. It is a non-well defined pathology difficult to both diagnosis and treatment. Because of its subtle nature, the real prevalence of chronic endometritis in the general population is ill defined, but is estimated between 0.8 and 19%. The implementation of protocols for screening of women, who have recurrent implantation failure after IVF with good quality embryo, is controversial, but some services have been using hysteroscopy in every patient immediately prior to FIV. However, there is no consensus on the effectiveness of hysteroscopy in improving the prognosis of infertile women. The findings suggest that the impact of chronic endometritis on fertility and outcomes should be further investigated in prospective randomized studies.

ABSTRACT

Introducción: La pérdida gestacional recurrente (PGR) es una patología frecuente, que causa gran impacto en las parejas conllevando frustración, ansiedad, depresión, gastos excesivos y hasta rupturas de la relación de pareja. Su etiología es multicausal y frecuentemente no se logra determinar . Se presenta el caso de una paciente con PGR quien luego de seis pérdidas gestacionales, en el séptimo embarazo se detectaron anticuerpos antifosfolípidos altos, recibiendo tratamiento de tromboprofilaxis doble hasta la semana 32, obteniéndose un producto pretérmino vivo y sano que evolucionó satisfactoriamente. Se discuten dificultades para la precisión diagnóstica y las modalidades de tratamiento descritos. [Salazar HA, Lancheros EA, Becerra CH. Uso de heparina de bajo peso molecular y aspirina en una paciente con síndrome antifosfolípido y pér-dida gestacional recurrente. MedUNAB 201 1;14(3):188-192].


Recurrent pregnancy lost (RPL) is a common condition that causes great impact on partners leading frustration, anxiety , depression, excessive spending and even breaks in the relationship. Its etiology is multifactorial and often can not be determined. This paper describes a case of a patient who after six RPL losses, in the seventh pregnancy is detected high positive antiphospholipid antibodies. She receive thromboprophylaxis twice a week until 32 weeks of gestational age, produced an healthy preterm newborn with a good prognosis. We discuss difficulties in the diagnostic accuracy and treatment modalities described. [Salazar HA, Lancheros EA, Becerra CH.

ABSTRACT

A análise morfológica da casca do ovo da avestruz é importante, pois diversos fatores morfológicos podem estar relacionados com a eclodibilidade do ovo desta espécie no Brasil. Para tanto foram analisadas 60 amostras de ovos aparentemente normais (ovos eclodidos e com morte embrionária). Foram efetuadas observações que permitiram estabelecer: a espessura média da casca do ovo, a porosidade da casca destes ovos, e correlacionar estas variáveis com a eclodibilidade. Os resultados foram analisados estatisticamente mediante o teste de Duncan, o que mostrou que ovos com menor porosidade tem também uma menor eclodibilidade. A porosidade média dos ovos eclodidos é de 19,87 poros/cm², e dos ovos com morte embrionária é de 16,78 poros/cm². Não houve diferença estatística entre a espessura da casca nas regiões estudada, nem interação entre viabilidade e as regiões.


Morphological analysis of the ostrich eggshell is important because several factors can be related to morphological hatchability of eggs of this species in Brazil. Therefore, 60 samples of apparently normal eggs were analyzed (eggs hatched and with embryonic death). The observations were allowed to establish that: the average thickness of the eggshell, the porosity of the shell of the eggs, and correlate these variables with hatchability. The results were statistically analyzed by Duncan's test, which showed that eggs with less porosity also have a lower hatchability. The average porosity of hatched eggs is 19.87 pores/cm², and of eggs with embryonic death is pores/cm2 16.78. There was no statistical difference between the thickness of the shell in the regions studied, no interaction between viability and the regions studied.

ABSTRACT

En un par de líneas de ratones seleccionadas para alto (s') y bajo peso (s), originadas a partir de una población no seleccionada de la cepa CF1 (t), se modificó la estructura ovárica. El diámetro de los folículos ováricos y el número de folículos y de cuerpos lúteos se incrementaron en las hembras de la línea s', sin expresarse en un mayor tamaño de camada al nacimiento, posiblemente, por un aumento de las pérdidas gestacionales. Se probó si los efectos conjuntos de la selección de peso a largo plazo y de la estimulación ovárica incrementaban las pérdidas gestacionales. Se utilizaron dos grupos de hembras por línea: sin y con estimulación ovárica (5UI de eCG y 5UI de hCG). Las hembras se sacrificaron a las 56-72 hs y a los 7 días postservicio y después de la primera parición. Se observaron los números de cuerpos lúteos (CL), embriones (E) y sitios de implantación (SI) y el tamaño de camada al nacimiento (TC). Se estimaron las pérdidas totales (PT) y las pérdidas de cuerpos lúteos (PCL), de embriones (PE) y de fetos (PF). Los promedios de CL, E, SI y TC variaron en el mismo sentido de la selección practicada y fueron significativamente mayores (P<0,05) para las hembras estimuladas, a excepción de TC. La línea s' tuvo un potencial reproductivo superior pero un mayor costo biológico (mayor PT y más tardía) cuando se la comparó con las otras líneas. La estimulación ovárica produjo menores eficiencias reproductivas totales para las tres líneas y pérdidas gestacionales mayores y más tardías, principalmente de SI. Las hembras de la línea no seleccionada (t), no estimuladas, con pesos intermedios, parieron un mayor número de crías, partiendo de un número intermedio de CL, E y SI, con una menor y más temprana mortalidad embrionaria, demostrando ser las más eficientes desde el punto de vista reproductivo y productivo.


The ovarian structure was modified as a consequence of weight selection in a pair of mouse lines selected for high (s') and low weight (s). Lines were founded from an unselected population of CF1 strain (t). The follicle diameter and the number of the ovarian follicles and the corpora lutea were higher in s' females, but they did not reach a larger litter size at birth, may be, by an increase in the gestational losses. In these lines, the co-effects of long-term weight selection and ovarian stimulation were tested to evaluate if they increased gestational losses. Two groups of females per line were employed: without and with ovarian stimulation (5UI of eCG and 5UI of hCG). Females were slaughtered at 56-72hs and at 7 days post-breeding and after first parturition. The number of corpora lutea (CL), embryos (E) and implantation sites (SI), and litter size at birth (TC) were observed. Total losses (PT) and corpora lutea (PCL), embryo (PE) and fetus (PF) losses were estimated. Mean CL, E, SI and TC varied in the same direction of the selection made and they were significantly higher (P<0.05) in stimulated females, though not for TC. Line s' had a higher reproductive potential but a greater biological cost (higher and later gestational mortality) when compared with the other lines. Ovarian stimulation produced lower total reproductive efficiencies for the three lines and higher and later gestational losses, mainly for implantation sites. Females from unselected line (t), without ovarian stimulation, with intermediate weights, bore larger litters, starting from an intermediate number of CL, E and SI, with a lower and earlier embryo mortality, showing to be the most efficient from a reproductive and productive point of view.

ABSTRACT

INTRODUÇÃO: O processo de luto devido à perda gestacional apresenta várias particularidades que devem ser consideradas no atendimento clínico daqueles que passam por uma experiência de aborto. Pacientes enlutados apresentam maior procura por assistência médica e número de hospitalizações e são mais vulneráveis a problemas psicossomáticos que a população geral. OBJETIVO: Apresentar um caso de tratamento de luto, decorrente de perda gestacional, com protocolo cognitivista comportamental. MÉTODO: O processo terapêutico foi composto por 12 sessões e o protocolo envolvia desenvolvimento de estratégias para lidar com as principais queixas somáticas, aprendizagem de novas habilidades, trabalho das alterações emocionais e cognitivas e treinamento para manejo dos problemas comportamentais. Os resultados foram avaliados por meio das escalas: Inventário Beck de Depressão, Inventário Beck de Ansiedade, Escala Beck de Desesperança e Questionário de Saúde Geral de Goldberg (QSG). RESULTADOS: O paciente apresentou redução nos sintomas de depressão e ansiedade, assim como em desesperança. Todos os fatores do QSG apresentaram redução, com forte declínio em "desejabilidade de morte" e "desordens psicossomáticas". Também foi notada melhora na qualidade de sono. CONCLUSÃO: O tratamento se mostrou efetivo em relação aos fatores apresentados, além de colaborar para melhor qualidade de vida e facilitação da reinserção social do paciente.


BACKGROUND: The grieving process due to a fetal loss has several features which should be considered in the clinical care of patients going through a miscarriage experience. Bereaved patients present greater demands for medical assistance, number of hospitalizations and are more vulnerable to psychosomatic problems than the general population. OBJECTIVE: This paper aims to present a case report of miscarriage grief treated with a cognitive behavioral therapy protocol. METHOD: The therapy was composed by 12 sessions and the protocol involves the development of strategies to deal with the main somatic complaints, learning of new abilities, approach to cognitive and emotional alterations and training to handle behavioral problems. Results were evaluated by Beck Anxiety Inventory, Beck Depression Inventory, Beck Hopelessness Scale, and Goldberg's General Health Questionnnaire (GGHQ). RESULTS: Patient presented reduction in depressive and anxiety symptoms. Hopelessness also decreased. All the GGHQ factors presented reduction, with a marked decline in "desire of death" and "psychosomatic disorders". It was also noted an improvement in sleep quality. DISCUSSION: The treatment showed itself effective in relation to the factors presented, apart from collaborating for a better quality of life and facilitating the social reinsertion of the patient.

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate its mechanism of inducing the maternal-fetal immune tolerance by studying the effects of Shoutai pills on the expression of Th1/Th2 cytokine and pregnancy in maternal-fetal interface of mice with recurrent spontaneous abortion (RSA).</p><p><b>METHOD</b>The normal pregnancy and RSA model were respectively induced with CBA/J x BALB/c and CBA/J x DBA/2. The mice with RSA were randomly divided into model group and low, middle and high dose groups of Shoutai pills. The mice were killed in 14 days after administration and embryo resorption rate was counted and their decidual and placental tissues were co-cultured to detect the expressions of IL-4, IL-10, IFN-gamma and TNF-alpha with ELISA.</p><p><b>RESULT</b>The embryo resorption rate of the model group was significantly higher than the normal pregnancy, middle and high dose groups of Shoutai pills could decreased the embryo resorption rate of the mice with RSA (P < 0.05). All the doses in 3 groups of Shoutai pills could decreased the expression of IFN-gamma and TNF-alpha (P < 0. 05) and there was no obvious difference between normal pregnancy group and all groups of Shoutai pills.

ABSTRACT

The effect of consanguinity on fetal loss and mortality and morbidity of offspring is the subject of controversy. We carried out a retrospective cross sectional study on 469 couples with fetal loss, among whom 237 [50.53%] couples had consanguineous union and 232 [49.47%] of couples had no consanguinity. Considering the prevalence of consanguinity in the population that is 23%, a relation between consanguinity and fetal loss can be elucidated, although for more accurate determination of this correlation we need to find the prevalence of consanguinity in couples with no history of fetal loss, i.e., designing a case control study

ABSTRACT

O objetivo deste estudo foi avaliar o efeito da linhagem e da idade das matrizes na perda de peso dosovos e no peso dos embriões, durante diferentes estágios da incubação artificial. Foram utilizados ovos de matrizes leves, semipesadas e pesadas, com amostragem às 30, 45 e 60 semanas de idade para cada linhagem. Foram retiradas amostras de cinco ovos por categoria no sétimo, décimo quarto e décimo nono dias de incubação para a análise estatística. Dessa forma, foi utilizado o delineamento inteiramente casualizado (DIC), com 27 tratamentos, em arranjo fatorial 3x3x3, e as médias comparadas pelo teste “t” Student, envolvendo distribuição normal a 5% de significância. Os ovos foram incubados em máquinas Petersime e submetidos à temperatura de 99°F (37,2°C) no termômetro seco, 84°F (28,8°C) deumidade e 1,1 m³/seg de ventilação. Estes foram pesados e abertos para retirada e pesagem dos embriões. Os resultados mostraram um aumento significativo na perda de peso dos ovos de matrizes leves e semipesadas durante a incubação, enquanto que as perdas de peso dos ovos de matrizes pesadas não variaram com o envelhecimento das aves reprodutoras.Isso sugere que ovos de matrizes pesadas apresentam uma melhor qualidade das barreiras contra evaporação e difusão de água dos ovos para o ambiente da incubadora, mesmo com o aumento da idade das matrizes. Os embriões de linhagem pesada apresentaram maior ganho tecidual durante a incubação, e maior peso durante a incubação em relação aos embriões das outras linhagens.


The aim of this research was to evaluate the effect of breeder hen strains and age on egg water loss and gain in embryonic weight during the different stages of artificial incubation. Eggs were used from light, midweight, and heavy breeder hens at 30, 45 and 60 weeks of age. For the study, 150 eggs were collected from each sample totaling 1350 eggs. For statistical analysis five eggs were candled per category on 7th, 14th e 19th days of incubation. The averages compared by the "t" Student test, involving normal distribution to 5%. These eggs were incubated in na electronically controlled incubator-Petersime machine at the temperature of 99°F dry, 84°F humidity with a ventilation of 1,1m3/seg. These embryos were also collected, extracted and their weight evaluated. Study results demonstrated that egg water loss was significantly greater in light strains and smaller in heavy ones (P smaller or equal to 0.05). This suggests a better quality in the barriers against evaporation and egg water diffusion in the incubator environment, considering the increase of the breeder hen´s age. Beyond that, it was also observed that the weighted strain showed greater tissue gain during incubation, and produced heavier embryonic in relation to the other strains.

ABSTRACT

<p><b>BACKGROUND</b>Previous studies have shown that local immune cells in the feto-maternal interface are recruited from peripheral blood, and that chemokines and their receptors play an initial and key role in this recruitment process. In this study, we aimed to determine whether spontaneous abortion is associated with the expression of chemokine receptors CCR3, CCR5, and CXCR3 on CD4(+) T cells.</p><p><b>METHODS</b>Peripheral blood, spleen, and thymus were collected from the spontaneous abortion mouse model CBA/JxDBA/2 (SA group, n = 14), the normal pregnant mouse model CBA/JxBALB/c (NP group, n = 13), and normal non-pregnant CBA/J mice (NNP group, n = 11). The number of chemokine receptors CCR3, CCR5, and CXCR3 expressed on CD4(+) T cells was measured by double-label flow cytometry (FCM) method.</p><p><b>RESULTS</b>In peripheral blood, the SA group had significantly lower CCR3 expression (P < 0.01) and higher CCR5 and CXCR3 expression (P < 0.01) on CD4(+) T cells than did the NP group. But comparing these chemokines between the SA and NNP groups, there was no significant difference (P > 0.05). In spleen, the SA group expressed significantly lower CCR3 expression (P < 0.01) and higher CCR5 and CXCR3 expression (P < 0.05) on CD4(+) T cells than did the NP group. When compared with the NNP group, the SA group had significantly higher CCR3 expression (P < 0.01), but was not statistically different with regards to the other two chemokines (P > 0.05). In thymus, the SA group had significantly lower CCR3 expression (P < 0.05) and higher CXCR3 expression (P < 0.05) on CD4(+) T cells than the NP group, with no significant difference in CCR5 expression (P > 0.05). Compared with the NNP group, the SA group had higher CCR3 expression (P < 0.01), but there was no statistical difference in CXCR3 and CCR5 expression (P > 0.05) between the two groups.</p><p><b>CONCLUSION</b>The abnormal expression of CCR3, CCR5 and CXCR3 on CD4(+) T cells may play an important role in the pathogenesis of spontaneous abortion.</p>

ABSTRACT

<p><b>BACKGROUND</b>Chemokines and their receptors have been a research focus in transplantation immunology. Chemokines and their receptors play a role in lymphocyte recruitment and differentiation process. This study aimed to observe whether IL-4 and IL-10 may regulate the expression of chemokine receptors CCR3, CCR5 and CXCR3 on CD4(+) T cells in CBA/JxDBA/2 mouse model and to explore the role of CCR3, CCR5, CXCR3 in immune tolerance in pregnancy.</p><p><b>METHODS</b>The mouse model of spontaneous abortion (CBA/JxDBA/2) and the normal pregnant mouse model (CBA/JxBALB/c) were used. CBA/JxDBA/2 mice were injected with IL-4 (CBA/JxDBA/2-IL-4), IL-4 and IL-10 (CBA/JxDBA/2-IL-4+IL-10), or normal saline (CBA/JxDBA/2-NS) as a control. The expression of CCR3, CCR5 and CXCR3 on CD4(+) T cells from mouse peripheral blood was measured by the double-labelled FCM method, and the embryo resorption rate was also examined.</p><p><b>RESULTS</b>The embryo resorption rate in the CBA/JxDBA/2 group without any treatment was significantly higher than that in the CBA/JxBALB/c group (17.9% vs 3.7%, P < 0.01). The embryo resorption rate in the CBA/JxDBA/2 group immunized with IL-4 or IL-4 together with IL-10 was significantly decreased, compared with that in the control and NS groups respectively. CCR3 expression on CD4(+) T cells in the CBA/JxDBA/2 group without any treatment was significantly lower than that in the CBA/JxBALB/c group (0.3738 +/- 0.3575 vs 1.2190 +/- 0.2772, P < 0.01); both CCR5 (3.0900 +/- 1.5603 vs 1.2390 +/- 0.6361, P < 0.01) and CXCR3 (2.4715 +/- 0.9074 vs 0.9200 +/- 0.5585, P < 0.01) expressions on CD4(+) T cells of the CBA/JxDBA/2 group without any treatment were significantly higher than those of the CBA/JxBALB/c group. Significant up-regulation of CCR3 and down-regulation of CXCR3 were found in the CBA/JxDBA/2 group treated with IL-4 (CCR3: 2.0360 +/- 0.6944, CXCR3: 1.3510 +/- 0.5263, P < 0.01) or IL-4 and IL-10 (CCR3: 1.8160 +/- 1.0947, CXCR3:1.0940 +/- 0.7168, P < 0.01). Because of the CCR5, IL-4 and IL-10 (1.9400 +/- 0.8504 vs 3.0900 +/- 1.5603, P < 0.05), but IL-4 alone (2.5310 +/- 1.3595 vs 3.0900 +/- 1.5603, P > 0.05) treatment significantly decreased the expression of CCR5 in CBA/JxDBA/2.</p><p><b>CONCLUSIONS</b>The abnormal expression of CCR3, CCR5 and CXCR3 on CD4(+) T cells may play an important role in the pathogenesis of spontaneous abortion. The pregnancy immune tolerance may be induced through selective induction of CCR3, CCR5 and CXCR3 expressions by IL-4 together with IL-10.</p>

ABSTRACT

Avaliaram-se estratégias para reduzir a mortalidade embrionária em bovinos. Vacas Nelore (Bos taurus indicus) foram inseminadas em tempo fixo (IATF - D0) após o protocolo GnRH/PGF2a/GnRH e divididas nos grupos: Controle (Gc; n=55), hCG (GhCG; n=55) recebeu 3000 UI da hCG no D5 , E2 (GE2; n=55) recebeu 5 mg de 17?-Estradiol (E2) no D12 e hCG/E2 (GhCG/E2; n=55) recebeu 3000 UI da hCG no D5 e 5mg do E2 no D12. A IATF foi o 1o dia da estação de reprodução de 64 dias. Usou-se o teste do c2 para comparar as taxas de serviço (TS), concepção (TC) e prenhez à IATF (TPIATF), às IAs de repasse e acumuladas. A TS e a TC das IAs de repasse não diferiu (P>0,10). Houve diferenças nas TPIATF (P<0,05), pois a TPIATF do GE2 (5,4%) foi a mais baixa e a do Gc (34,5%) e GhCG (36,5%) tenderam (P<0,10) ser maiores que a do GhCG/E2 (18,2%). Não houve efeito da hCG sobre as taxas de prenhez. O E2 reduziu a TPIATF e ao final da estação as vacas que receberam o E2 (GE2 + GhCG/E2) tiveram TPacum (66,4%) mais baixa (P<0,05) de que aquelas (80,9%) que não receberam (GC + GhCG). Em conclusão, as estratégias adotadas de manipulação luteínica ou folicular não aumentaram as taxas de prenhez em vacas Nelore após uma IATF.


Strategies to reduce embryo mortality in cattle have been evaluated. Nelore (Bos taurus indicus) cows were submitted to timed artificial insemination (TAI - D0) after a GnRH/PGF2a/GnRH protocol. Cows were divided in the following groups: Control (Gc; n=55), hCG (GhCG; n=55) received 3000 IU of hCG on D5 , E2 (GE2; n=55) received 5 mg of Estradiol-17b (E2) on D12 and hCG/E2 (GhCG/E2; n=55) received hCG on D5 and E2 on D12. TAI represented the 1st day of a 64 day breeding season. The c2 test was applied to compare mating rate (MR), conception rate (CR) and pregnancy rate (PR) to TAI and AIs after natural estrus within the season as well as their accumulated figures at the end of the season. MR and CR for AIs within season did not differ (P>.10). PR to TAI differed (P<.05) among groups. GE2 showed the lowest rate (5,4%). Gc (34.5%) and GhCG (36.5%) tended (P<.10) to be higher than GhCG/E2 (18.2%). There was no effect of hCG on pregnancy rates. E2 reduced PR to TAI and at the end of season which means that cows receiving E2 (GE2 + GhCG/E2) had lower (66.4%; P<.05) PR than cows not receiving E2 (GC + GhCG; 80.9%). In conlusion, the strategies to manipulate luteal and follicular function herein tested did not increase pregnancy rates in Nelore cows submitted to a TAI.
