Abstract: Na aqüicultura brasileira, formula es à base de diflubenzuron para uso agrícola s o utilizadas indiscriminadamente no controle de ectoparasitas de peixes. Na ausência de formula es para uso em peixes cultivados, surgem protocolos terapêuticos repletos de incertezas quanto à sua eficácia, impacto ambiental e perfil hematológico dos peixes. O objetivo deste trabalho foi avaliar o efeito do diflubenzuron sobre os seguintes parametros hematológicos de jundiás (Rhamdia. quelen) infestados por Lernaea cyprinacea: número total de eritrócitos, número total de leucócitos, hematócrito e contagem diferencial de leucócitos. Jundiás divididos em 4 grupos foram expostos a banhos de imers o de 24 horas com diflubenzuron nas concentra es: 0,0 mg.L-1 , 0,01 mg.L-1, 0,1 mg.L-1 e 1,0 mg.L-1. Essas concentra es n o apresentaram diferen as significativas na hematologia (teste Tukey p<0,05). Novos trabalhos devem pesquisar o efeito do diflubenzuron sobre em períodos de exposi o prolongados, para verificar a existência de efeito cr nico atribuído ao princípio ativo. There are no specific formulations of diflubenzuron for the treatment of ectoparasities in freshwater fishes. Many therapeutics protocols of untested efficacy, environmental impact and unknown hematological effects have been introduced in Brazilian aquaculture. The aim of this study was evaluate the diflubenzuron effect on the hematological parameters (total number of erythrocytes, hematocrit, total number ofleucocytes and differential count of leucocytes) of “Jundias” (Rhamdia. quelen) infected by Lernaea cyprinacea. Four groups of jundias were exposed to a 24 hour immersion bath containing diflubenzuron in concentrations: 0.0 mg.L-1, 0.01 mg.L-1, 0.1 mg.L-1 and 1.0 mg.L-1. These concentrations of diflubenzuron did not show any significant difference in the basal parameters of hematology (Tukey test p<0.05) of Jundias. More studies about the effect of diflubenzuron on the hematology of infected fishes exposed to a long period of treatment are needed to test chronic effects.

Abstract: Given increasing demand for timely and accurate information to support decision making, hospitals, a particularly complex type of service organization, have increasingly resorted to a wide range of tools such as the Clinical Information Systems (CIS). However, research has shown that such systems do not always meet hospital managers’ needs, and assessment processes are necessary both before and after CIS implementation. Aiming to identify whether the CIS do meet hospital managers’ information needs and do fit in the specificities of such organizations, this paper reports on the assessment of four CIS based on the perspective of their users in four hospitals in the Metropolitan Region of Belo Horizonte, State of Minas Gerais, Brazil. The data was collected by means of semi-structured interviews and non-obtrusive observation. On the one hand, the result shows that the four organizations have difficulties in using their systems, such as accessibility problems, inadequate training and system underutilization. On the other hand, they also benefit from such systems, as they make processes faster and enable information control. One can say that the results from this research contribute to a better understanding of evaluating information systems in hospitals. Managers of such organizations can benefit from these results when seeking to evaluate and improve their information systens.

Abstract: The effects of therapeutics products and other poluents over fish sperm have been research issues. The diflubenzuron (DFB) is widely used against fish ectoparasites. For USA and Europe, its use is restricted, due the large potential of environment impact; but in south of Brazil, is used by most of fishfarmers on 24 hours’ immersion bath. The present study submitted 64 jundias (Rhamdia quelen), infested by Lernaea cyprinacea under four treatments (0,0mg/L; 0,01mg/L; 0,1mgmg/L and 1mg/L) at immersion bath during 24 hours. At final of experimental period, we carried through the collect and evaluation of fish sperm. No differences were found over evaluated parameters: volume, aspect (appearance and color), motility duration and concentration of sperm. The product showed inefficient as 24 hours’ immersion bath against adult parasites and copepodites. Os efeitos de produtos terapêuticos e outros poluentes, sobre a produ o espermática de peixes têm sido objeto de pesquisas. O diflubenzuron(DFB) é muito utilizado no tratamento de ectoparasitos de peixes, sendo que nos Estados Unidos e Europa seu uso é controlado em fun o do grande potencial de impacto ambiental. No Sul do país, muitos produtores utilizam o DFB em banhos de 24 horas numa única aplica o. O presente trabalho submeteu 64 jundiás (Rhamdia quelen) infestados por Lernaea cyprinacea a quatro tratamentos, grupo controle e três doses de DFB, (0,0mg/L; 0,01mg/L; 0,1mg/L e 1mg/L) sob a forma de banhos de imers o num período de 24 horas. Ao final do período experimental, foram realizadas a coleta e a avalia o do sêmen dos peixes. N o houve diferen a entre os parametros avaliados: volume, aspecto (aparência e cor), dura o da motilidade e concentra o espermática. O produto mostrou-se ineficaz em banhos de 24 horas para parasitos adultos e copepoditos.

Abstract: a limiting factor in the early stage of the jundiá (rhamdia quelen quoy; gaimard, 1824) culture is the presence of diseases such as ichthyophthiriasis or "ich". dietary polyunsaturated fatty acids (pufas) have a potent immunomodulatory activity; and this activity depend of the fish species, quantity/quality of the dietary pufas. the aim of this study was evaluate the physiologic response ofjundiá, rather fed diets with different sources of fatty acids when challenge to ich disease. fingerlings ofjundiá (7.6±0.8g) were fed during seven weeks with five diets with a different lipid source: fish, linseed and corn oils. then, the fish were challenged with the ichthyophthirius multifiliis (fouquet, 1876). on the 5th day, the presence of the disease was detected. survival rate, blood samples and infection grade were recorded. diets affect the survival rate of fingerlings, thus fish fed with diet with fish oil showed a higher survival. hematocrit and infestation grade no recorder differences among treatment. the differential analysis of white blood cells shows difference. the results point out, at first time injundiá, that dietary lipids caused diversity physiologic response, this may be represent an opportunity for the disease treatment. new studies must be carrying out to deep knowledge found.
