This study aimed at examining the representation and the level of knowledge as well as getting acquainted whether there had been significant divergence among three social groups of 3rd year Law students, 7th period Medical students at UFPB and a group of people from the Catholic Church in vila dos pescadores in João Pessoa - about organ donation, transplant law and ethical issues that raise questions. In order to accomplish the qualitative analysis, Bardin´s content analysis technique was applied in conjunction with the Chisquare test which was applied with significance level of 5% to quantitative data. The data revealed that most informants agree with organ donation, Although they are not acquainted with the law of transplants, and with the lack of confidence in the single list of recipients. The problem is that there is an encouragement to trades with organs and the possibility of any person legally authorized to donate organs in life. The statistically significant difference was observed in only two questions, ie, in response to the confidence in the diagnosis of brain death: 64% of 7th period Medical students at UFPB trust this diagnosis versus 12% of the evangelizing group of vila dos pescadores. The other difference refers to the answer about the confidence in the single list of recipients: 36% of the 7th period Medical students of UFPB said to trust the list versus 12% of the 3rd law students of UFPB. This is was a multidisciplinary study with Involvement of lawyers and doctors

The present study examined the relations of power in the management of the Escola Estadual Presidente Kennedy, including the deliberate decisions on the School Council and School Fund, which guided the organization of the school. We sought to understand the management models that influenced the school organization, promoting contradictions in the decision making process. The school management is intensely marked by management models from the business logics as in the case of managerialism of bureaucracy. The formulation of educational policies based on managerialism has proposed a school-centered management with intense accountability of the school community in planning and monitoring the public services. The influences of these models subsidize hierarchical power relations that undermine the actions of decision-making of the collegiate bodies for the democratization of school management. To develop a research on the power, the investigation was based on studies of Bourdieu and Foucault. These authors understand the power in a relational system in a double sense, both in terms of discipline and the possibility of resistance. A theoreticalmethodological matrix was developed focusing on literature review, document analysis, structured interviews with twelve representatives of the segments belonging to the School Council and School Fund, as well as observations in meetings with the production of field notes. It was found that power relations experienced in the organization and activities of the school boards are marked by changes in public management over the years, promoting the contradictions between the concepts of corporate management originated in the business logics and the perspective of democratic management subsidized by official legislative documents at the national and state levels. The observations in meetings and analysis of the records showed that representatives related to management (president and manager of the school) have a privileged position with regard to exposure of their propositions, and are more likely to take a position in the political game of the collegiate bodies of work. It was also seen that the irregularity of meetings, particularly of the School Fund meetings, limits the experience of operation of the representatives in discussions concerning the planning and monitoring the actions of school management. Reports from representatives of the School Council showed that certain segments related to the management recognize their power of decision, however others have little interfere in the decision-making process in order to expound the desires of those who are represented by them. In the School Fund, the analysis of the records and interviews showed restricted moments of the meeting of representatives, and these only being aimed at choice or approval of the implementation plan prepared by the school management. The results showed no indications of moments of reflection to study the best chance for applicability of resources. This collegiate body (School Fund) has a questionable action when planning and monitoring the applicability of the financial resources of the School. To sum up, it was found that the Escola Estadual Presidente Kennedy still lives hierarchical power relations that undermine the institutionalization of democratic management in the various representative segments may take place in the game of political decision-making processes necessary for the organization of the school

The transplantation of organs and tissues presents itself as an important therapeutic option, both from a medical standpoint, the social or economic. Thus, the identification of variables that can interfere in the effectiveness of organs and tissues donation for transplantation needs to be investigated adequately, because it stands before increasing index of chronic and degenerative diseases in the population, what makes the waiting list for transplantation grow disproportionately and patients come to death without the opportunity of realization the treatment due to a lack of donors. In this context, has defined as objective of this study evaluate the factors associated with the effectiveness of organs and tissues donation for transplantation. It is a evaluative research, quantitative, prospective, with longitudinal design, developed at Central of Catchment, Notification and organ donation for transplant, Organ Procurement Organization and in six accredited hospitals to collect and transplantation of organs and tissues, in Natal/RN, between august 2010 and february 2011, after the approval of the Research Ethics Committee, under No. 414/10 and CAAE 007.0.294.000-10. The probabilistic sample without replacement was composed of 65 potential donors. It was used as an instrument of data collection a structured script non-participant observation of checklist type. Data were analyzed using descriptive statistics and presented in tables, charts, graphs and figures. For this, was used Microsoft Excel 2007 and statistical program SPSS version 20.0. To check the level of significance was chosen by applying the chi-square test (χ2) and Mann Whitney and caselas for less than five, it is considered the Fisher exact test. It was adopted as the significance level p-value <0.05. Among the surveyed it was observed that most of the individuals were male (50,8%), in the age group 45 years (53,8%), mean age of 42,3 years, minimum 5 and maximum 73 years (± 17,32 years). Single / widowers / divorced (56,9%), with up to completed elementary school (60,0%) in the exercise of professional activity (86,2%), catholic (83,1%) and residents in metropolitan region of Natal (52,3%). Was obtained donation effectiveness of 27,7%. There was no statistical significance between structure and effectiveness of the donation, but were observed inadequacies in physical resources (36,9%), materials (30,8%), organizational structure (29,2%) and human resources (18,5%). In the process, the maintenance phase (p= 0.004), diagnosis of brain death (p= 0.032), family interview (p≤ 0.001) and documentation (p= 0.001) presented statistical significance with effectiveness. Thus, it is accepts the alternative hypothesis of the study, in which is evidenced that the adequacy of the factors related to structure and process is associated to effectiveness of organs and tissues donation for transplantation. In this way, the effectiveness of organ and tissue donation ends in an essential way the rapidity and accuracy with which the donation process is conducted, requiring appropriate structure, with appropriate physical and material resources and skilled human resources to optimize the reduction of time and the suffering of those waiting for an organ or tissue transplant queued in Brazil

Despite of the technological advances that favor the transplant process, there are issues of effectiveness of care necessary for the maintenance of potential organ donors with brain death, which contribute to the no realization of transplants of organs and tissues of these patients. It is presupposed that the problems could be related to perceptions and understandings that the professionals of the units of internment have about the care required by the diagnosis of brain death. The aim of this study was to understand the meaning of the nursing care of the potential organ donor with brain death to the nursing staff. Descriptive study with qualitative approach guided by Action Science Theory and the critic-reflexive research methodology accomplished with five nurses and 19 nursing technicians from Operative Rehabilitation Center in a public hospital at Natal / RN, Brazil, between March and May 2013. Data were collected through semi-structured interviews with individual reflection about the care and through group interview, after approval by the Ethics and Research Committee, CAAE No.: 04255612.7.0000.5537. The analysis was performed in a thematic way according to Bardin. During the group meeting the participants were driven in a discussion about the need for change and how to perform them. The results indicate that the professionals actions are consistent with those required for maintenance of potential organ donors, although the material and human resources are not adequate. That situation leads the professionals to develop a meaning of care as one labor more, demanding more than they can give. They express beliefs and feelings concerning the hope that their care brings a greater good that is to save lives. The reflection for a possible change of action was difficult to accomplish due to professionals not to be able to self evaluate, what lead to direct your changes suggestions for other team members. It is concluded that the care provided to these patients is a difficult care, evidenced by suffering both death situation of the person cared and pain of their families, as the dehumanizing conditions of work, helping themselves to keep distance from patients to not suffer so much. The knowledge impregnated in their act, are scientific, ethical, aesthetic and personal kind with a predominance of the scientific followed by the personal. The study was also relevant to the practice of nursing in maintaining the potential donor, in that it allowed the identification of the knowledge used by nurses in their care practice and the meaning understanding of the professionals on the care provided, as a good action that brings satisfaction when the transplanting is executed. Other experiences are suggested with the critic-reflexive research methodology, both in research as in teaching nursing

Quarenta bovinos machos, com peso médio de 371 kg, foram distribuídos em um delineamento em blocos casualizado com esquema fatorial 3x3, dos quais quatro foram abatidos no início do experimento como referência, para avaliar a biometria das carcaças e o peso de vísceras e órgãos internos quando alimentados com diferentes fontes protéicas (uréia, Amiferm e farelo de soja) e volumosos (cana-de-açúcar e a silagem de milho e pastagem de capim Brachiaria brizantha). Não houve interação significativa volumosos x fontes protéicas e não houve diferença significativa entre as fontes protéicas para os parâmetros estudados. Para os volumosos, os pesos (em porcentagem do peso do corpo vazio - % PCV) do conteúdo estomacal (CRROA) e do conteúdo gastrintestinal (CGI) foram significativamente maiores para os animais alimentados com cana-de-açúcar (7,52 e 8,59% PCV, respectivamente) e não diferiram entre os alimentados com silagem de milho e capim, com médias de 5,10% PCV, para CRROA, e 5,89% PCV para CGI. Os animais mantidos em pastagem não apresentaram compacidade das carcaças diferente dos animais alimentados com os outros volumosos, enquanto os alimentados com cana-de-açúcar mostraram ser menos compactos que os alimentados com silagem de milho. As fontes protéicas também influenciaram a compacidade, que foi menor nos animais que receberam Amiferm e iguais para os que receberam uréia e farelo de soja. Conclui-se que os animais alimentados com cana-de-açúcar apresentam maior enchimento dos compartimentos digestivos e carcaças menos compactas.

A doação de órgãos é um problema de relevância social e científica, pois envolve as formas como a vida é perpetuada através do corpo de outra pessoa, especificamente por meio de seus órgãos. Quais são os fatores de resistência e de facilitação à doação de órgãos? Este artigo propõe um fator de resistência e um de facilitação. O primeiro, o narcisismo pelo próprio corpo; o segundo, o desejo de perpetuar-se a si mesmo e a vida.

A oclusão e reperfusão das artérias esplâncnicas ocasiona choque circulatório, causado principalmente pelo aumento de permeabilidade vascular e pela agressão celular provocada por radicais livres derivados do oxigênio. Este estudo tem por finalidade verificar a ação do extrato de Ginkgo biloba (Egb-761) e do amido hidroxietílico (AHH) na prevenção do choque circulatório produzido pela isquemia e reperfusão de órgãos esplâncnicos. O Egb-761 tem propriedades antioxidantes relatadas na literatura. O AHH, tem sido utilizado como recurso terapêutico do choque hipovolêmico. Ratos anestesiados receberam infusão contínua de Egb-761 ou AHH, sendo submetidos à isquemia (oclusão do tronco celíaco, artéria mesentérica superior e artéria mesentérica inferior por 30 minutos) e reperfusão (por 90 minutos) dos órgãos esplâncnicos. Foram feitas: análise histopatológica ileal, dosagem de malondialdeído ileal e determinação contínua da pressão arterial média (PAM). A PAM ao final do período de reperfusão foi significativamente mais elevada nos animais tratados com Egb-761 e AHH, que no grupo controle (F=18,29; p<0,001). Não houve diferença entre os grupos tratados e controle quanto à dosagem de MDA (H=4,61; p>0,10) e quanto às alterações histológicas (H=6,003; p>0,10). em conclusão, houve melhora nas condições hemodinâmicas, com atenuação do choque nos ratos que receberam Egb-761 ou AHH. Novos estudos serão necessários para se avaliar melhor as alterações histológicas e para esclarecer a formação de produtos finais da peroxidação lipídica.

Objetivo: estudar as repercussões da hipertensão arterial sobre o peso e comprimento corpóreo e sobre o peso do fígado e do cérebro de recém-nascidos (RN). Métodos: foram utilizadas 82 ratas virgens da raça Wistar em idade de reprodução. Após a indução da hipertensão arterial experimental (modelo Goldblatt I: 1 rim - 1 clipe) as ratas foram sorteadas para compor os quatro grandes grupos experimentais (controle (C), manipulação (M), nefrectomia (N) e hipertensão (H). A seguir, as ratas foram distribuídas por sorteio em 8 subgrupos, sendo quatro grupos prenhes e quatro grupos não-prenhes. Após acasalamento dos quatro grupos prenhes, obtivemos com o nascimento dos recém-nascidos os seguintes grupos: RN-C, RN-M, RN-N e RN-H, respectivamente controle, manipulação, nefrectomia e hipertensão. Resultados: quanto ao peso e comprimento corpóreo dos recém-nascidos observamos que os grupos RN-N e RN-H apresentaram os menores pesos e comprimentos em relação ao seus controles. Quanto ao peso do fígado os RN-H apresentaram os menores pesos em relação aos seus controles. Conclusão: a hipertensão arterial determinou redução no peso corpóreo, no comprimento, no peso do fígado e no peso do encéfalo dos recém-nascidos.
