Estómago de Conejo: Modelo Animal para Cirugía Experimental Rabbit Stomach: Animal Model for Experimental Surgery
María Teresa Halabi,Francisca Bahamondes,Gino Cattaneo,Luis Adaro
International Journal of Morphology , 2012,
Abstract: La cirugía veterinaria experimental en peque os animales, particularmente en perro, tiene principalmente restricciones de tipo afectivas, por lo que es necesario contar con otro modelo animal, para poder realizar diferentes procedimientos destinados a su aplicación en dicha especie. Dicho modelo debe cumplir con características anatómicas homologables al perro y también con facilidades de uso y manejo. Al ser una especie tradicionalmente utilizada en experimentación, el conejo podría constituir un excelente modelo animal para este propósito. El objetivo de este estudio es describir la anatomo-topografía del estómago del conejo para luego compararla con el perro. Se utilizaron 14 conejos que fueron sometidos a distintas técnicas de conservación para su estudio anatómico posterior; los instrumentos y materiales para realizar dicho estudio morfológico y un registro bibliográfico de parámetros anatómicos del estómago del perro. Los resultados de este ensayo muestran que el conejo posee un estómago de morfología, ubicación y orientación similar a la del perro, con algunas variaciones en sus relaciones con otras estructuras anatómicas. Asimismo la irrigación de este órgano es muy similar a la del perro. De acuerdo a lo observado, en estómago, el conejo podría ser utilizado como modelo animal para someter a prueba distintos ensayos quirúrgicos experimentales. Experimental veterinary surgery on small animals -particularly dogs- has restrictions, mainly regarding affect; therefore it is necessary to have a model of the animal to perform such procedures. This model must have anatomic characteristics which homologate those of dogs, but it must also fulfill ease of use and handling. Being a species traditionally used in experimentation, rabbits could be an excellent animal model for this purpose. The goal of this study is to describe the anatomotopography of the stomach of the rabbit and then compare it with the dogs. Three elements were considered: 14 rabbits exposed to various conservation techniques for their later anatomical study, the instruments and supplies to develop such morphological study and a bibliographic record of anatomical parameters of the dog's stomach. The results of this essay show that rabbits have a stomach with a morphology, location and orientation similar to the one of a dog, varying on its relation to other anatomical structures, the irrigation of this organ is as well very similar to the one of the dog. According to what was observed on the stomach, rabbits may be used as an animal model to perform different experimental surgical essays.

Abstract: purpose: due to the scarce information available in brazil in relation to the number of women who initiated the use of combined oral contraceptives and prematurely discontinued, the objective was to assess the reasons for discontinuation of the use of several combined oral contraceptives among brazilian women living in urban areas. methods: a cross-sectional study with 400 gynecologists registered withy the brazilian federation of obstetricians and gynecologists. each physician interviewed 10 non-pregnant, not breastfeeding, not amenorrheic women aged 18 to 39 years who consulted requesting combined oral contraceptive (coc) with a questionnaire at the beginning of use and at six months later. the questionnaire included sociodemographic data, type of coc chosen or prescribed and reasons for discontinuation when it occurred during follow-up. the strategy of selection allowed the inclusion of women from different socioeconomic strata, however, only those attended at private or insurance offices. the sample size was estimated at 1,427 women. results: a total of 3,465 interviews were conducted at the first visit and 1,699 six months later. the women were 20 to 29 years old, 57.3% were single and an equal proportion of 45.0% attended high school or college. most (60.7%) were nulligravidas and among those who had used some contraceptive before, 71.8% had used a coc. among the more prescribed or chosen coc the most prevalent were monophasic with ethynil estradiol (20 μg) and regarding progestin the most prevalent was with gestodene (36.5%) followed by a coc with drosperinone (22.0%). at six months 63.5% still used coc. among those who discontinued the main reasons were wishing to become pregnant (36.5%) and side effects (57.3%) and the most prevalent were headache (37.6%), weight gain (16.6%) and irregular bleeding (23.6%). conclusions: the continuation rate of coc was low at six months and this study could contribute to a better counseling on the part of physicians of pati
Physician-patient communication in the prevention of female reproductive tract infections: some limitations

Abstract: the objective of this study was to describe the information that women with tubal infertility recalled having received from physicians when they consulted for a reproductive tract infection (rti) and the information physicians reported having provided to women consulting for rtis. interviews were conducted with 16 women presenting primary tubal infertility selected on the basis of purposeful sampling criteria. also, 15 physicians working in the public health network in the city of campinas, brazil, were selected at random and interviewed. analysis of the women's statements concerning previous rti-related medical consultations showed that they did not recall having received any information on either prevention or the impact of rti on their reproductive future. analysis of interviews with physicians showed that the information they provided to women consulting for rtis was incomplete and unclear. the information women recalled having received and that which physicians remembered having provided at the time of treating a patient with rti was similar. in conclusion, these women lacked adequate or complete information and that it was probably not possible for them to adopt measures to avoid repetition of rti and minimize risk of tubal infertility.

Abstract: The objective of this study was to describe the information that women with tubal infertility recalled having received from physicians when they consulted for a reproductive tract infection (RTI) and the information physicians reported having provided to women consulting for RTIs. Interviews were conducted with 16 women presenting primary tubal infertility selected on the basis of purposeful sampling criteria. Also, 15 physicians working in the public health network in the city of Campinas, Brazil, were selected at random and interviewed. Analysis of the women's statements concerning previous RTI-related medical consultations showed that they did not recall having received any information on either prevention or the impact of RTI on their reproductive future. Analysis of interviews with physicians showed that the information they provided to women consulting for RTIs was incomplete and unclear. The information women recalled having received and that which physicians remembered having provided at the time of treating a patient with RTI was similar. In conclusion, these women lacked adequate or complete information and that it was probably not possible for them to adopt measures to avoid repetition of RTI and minimize risk of tubal infertility.
Re-pensando el orden colonial: los intercambios hispano-indígenas en el fuerte del río Negro
Luiz,María Teresa;
Mundo agrario , 2005,
Abstract: the study of cross-cultural processes in the colonial frontiers in latin america shows keys to explain the dynamics of interethnic relationships, acculturation experiences and construction of identities. likewise, the functioning of the colonial order can be analyzed from the ways the power relationships were structured in the areas where the aborigines preserved autonomy and crontrol of their territories and resources. hispanic-native relationships are studied from this theoretical point of view, in one of the last borders where the hispanic expansion got since the bourbon's duty imposed, that is the southernmost territories of río de la plata. analyzing the ways of interaction in the río negro fortress, we identified the hispanic-local and aboriginal strategies and recognize the stabilization of a transaction assemblage that defined a special regime of interchanges based on reciprocity. these political and economic practices favoured the maintenance of certain balance of forces, which is shown in the decrease of frontier struggle during the last decades of the colonial period.
El peronismo revisitado: Rupturas y continuidades de un debate que no pierde su centralidad
Brachetta,María Teresa;

Abstract: this article explores the deep renovation in the ideological-cultural field that accompanies the return to democracy in the country, as well as the processes that bring about the formation of a new "cultural atmosphere". besides, through the conceptual and methodological news in the field, it analyses the production that aims at revisiting peronism at that time. in so doing, it attempts to tackle the continuity of the lines of the debate that started in previous decades, as well as a whole new line that at the beginning of the 80s began with the analyses of the "cultural battle" between politicians and intellectuals brought about by peronism after its first decline. the magnetism of peronism over the historiographical field in the 60s and 70s acquires a renewed vigour in the 80s, due to the political and ideological disputes and controversies in the interior of this political tradition in the period of the democratic transition. this new production is undoubtedly a fundamental chapter in the historiography of peronism, which continues in the following decades and inspires new readings. in this sense, this article attempts to join old and new ideas in the historiographical field, modulated by the changes in peronism as a political force since its electoral defeat against radicalism in 1983.
La elipsis en la interacción comunicativa y variación sociolingüística
Poblete,María Teresa;
Estudios filológicos , 2002, DOI: 10.4067/S0071-17132002003700007
Abstract: the purpose of this study is to identify and classify occurrences of ellipsis in question-answer and other rejoinder sequences in the interview, to establish its contribution to oral textual coherence. sociolinguistic variations derived from strata, age and sex of participants are also described. the corpus was taken from eighteen interviews to valdivian speakers, men and women, divided into three social strata and three age groups. the results show the significant presence of ellipsis in communicative interactions, its contribution to topic progression and to the coherence of the oral texts analyzed. the sociolinguistic variation shows to be derived from the speakers' decisions with respect to what they say, and their attitudes towards the interviewer's observations (questions and other utterances). the interviewees' attitude showed significant differences among strata, between men and women, and between the youngest generation and the two older ones.

Pinto,María Teresa;
Análisis Político , 2005,
Abstract: bolivia is the only country of south america which has gone through a popular revolution of important political and social dimensions. it had to support one of the most severe and repressive dictatorships of the andean region and at present has encountered democratic stability. which factors help to explain this trajectory? and, furthermore, what factors have contributed to establish the democratic periods in this country? this article attempts to compare such democratic processes through points of encounter which permit to respond these questions, besides knowing the conditions which favor the government alliances and democratic stability and not authoritarian stability. the authoress uses yashar?s methodological approximation which proposes to analyze coalitions in favor of the establishment of democracy in a determined country.
