Avaliar efeitos do uso tópico do mel da abelha silvestre Melipona subnitida na evolução de feridas infectadas de pele. Método: Ratos Wistar foram distribuídos aleatoriamente em grupos de 6, anestesiados com tiopental sódico 20mg/Kg IP e cetamina 30mg/Kg IM e submetidos a exérese de segmento de 1 cm2 de pele total do dorso. Os ratos do grupo C (não infectado) foram tratados com solução salina sobre a ferida diariamente e no grupo MEL (não infectado) as feridas foram tratadas com mel uma vez por dia. Nos grupos C/I e MEL/I as feridas foram inoculadas com solução polimicrobiana. Culturas foram feitas 24 horas após. Caracterizada a infecção, as feridas foram tratadas com solução salina e mel, respectivamente. No terceiro dia de tratamento foi feita nova cultura. Após epitelização foi contado o tempo de cicatrização e as feridas foram biopsiadas para histopatologia e dosagem de TNF-a, IL-1b e IL-6 no tecido. Resultados: O tempo médio de cicatrização do grupo MEL/I foi menor que nos demais grupos(P<0,05). Verificou-se que a densidade de colágeno, leucócitos, fibroblastos e dosagem de citocinas (especialmente TNF) foi maior no grupo infectado e tratado com mel que nos demais grupos. Houve significante redução de bactérias Gram-negativas e positivas nas feridas após o tratamento com mel. Conclusão: O uso tópico de mel de Melipona subnitida em feridas infectadas da pele de ratos estimulou a resposta imunológica, reduziu a infecção e o tempo de cicatrização

O trabalho teve como objetivo conhecer o melhor tipo de mel em relação à longevidade e fertilidade do parasitóide do bicudo-do-algodoeiro Catolaccus grandis. Adultos recém-emergidos foram transferidos para recipientes plásticos de 500mL, adaptados com tubo para fornecer água e umidade para os insetos. Um casal do parasitóide foi mantido em cada recipiente em câmara climatizada a 25±1°C, UR = 70±10% e fotoperíodo de 14h. O trabalho constou de 4 tratamentos: mel de flor de laranjeira; mel de flores de plantas silvestres; mel de cana-de-açúcar (todos produzidos por Apis mellifera) e mel de flores silvestres produzido por abelha Jataí (Tetragonistica angustula), com 15 repetições cada. Adultos recém-emergidos do parasitóide receberam cinco larvas de Euscepes postfasciatus encapsuladas em parafilm. Três gotículas de mel foram colocadas sobre o parafilm. Calculou-se a longevidade de machos e fêmeas, número de ovos dia-1 fêmea-1 e número total de ovos fêmea-1 e construíram-se as tabelas de fertilidade. As melhores dietas para alimentar adultos de C. grandis foram o mel silvestre e o de laranjeira. A melhor fecundidade foi observada na dieta de mel de laranjeira (101,60 ovos fêmea-1) e os melhores resultados para aumento reprodutivo e populacional deste parasitóide foram obtidos com mel de laranja e com mel silvestre.

The beekeeping activity has become in all regions of Brazil until the early 80s and from 2000 to beekeeping Northeast also has developed, becoming a major oil producing honey. The Rio Grande do Norte following these developments happened to occupy fourth place in the ranking of export of honey between the states of the Northeast in 2007. Therefore, the aim of this paper is to present a macro radiography of recent developments in the production chain of honey in the state of Rio Grande do Norte, organizing and discussing the information, collected in the period 2004 to 2007, as well as evaluating the prospect of the honey industry in order to provide a diagnosis able to identify opportunities and enhance the marketing of their products. From the methodological point of view, this study can be classified as a research study exploratory and descriptive by using questionnaires. The group of several studies has been productivity, production and market. Search results indicated the growth of industry in 4 years of activity by the number of beehives full and populated, infrastructure, production and marketing of the state. It can be said that beekeeping of Rio Grande do Norte, despite its potential for developing the activity comes in a different way when compared to other activities, because the actors who play to start the activity through training and to play with it in a professional manner, in addition to support staff who work in the industry

This thesis approaches the situation of small and medium Brazilian companies facing the exportation process, focusing honey (Apis Mellifera). The world economy has had growing market internationalization, known as globalization. In this context, the exportation has to be faced as a way to minimize the inner market difficulties and increase the levels of quality and productivity to attend the external markets in a competitive way. A company exportation process is not linked to its dimensions, but connected to the commitment with quality, creativity and professionalism. The search for new productive frontiers has benefited Brazilian beekeeper, mainly the northeast ones. Besides, the claim for products that are free of chemical remains, with a bigger aggregate value has increased every day, and the Apismel Company is benefited for having potential to produce organic honey. This paper approaches a case study realized with Sixty-nine beekeeper from Serra do Mel, RN, that make the Apismel Company and it aims to investigate the competitive factors that affects honey exportation. In order to obtain subsidies to execute the objective of this work, it was chosen a questionnaire as instrument of research. The questionnaire was structured from variables that were considered as directions of competition in honey exportation. The results were tabled in Software (Statistics version 11.0). The descriptive, exploiter and Kolmogorov-Smirnov analyses were used to analyze the obtained results. At the end, this work recommends that the Apismel Company promote capacitating courses and technical consultations at the many villages that make the county, to ripen and add efficiency in handling implementation in order to equilibrate production factors and to attract inner and external markets

The present study makes an analysis of the Development Program of Beekeeping on Rio Grande do Norte, evaluating the model of management implanted for the SEBRAE/RN in the production of bee honey in Rio Grande do Norte; on the basis of the annual reports emitted by the company in 2003, 2004 and 2005 a discerning survey is done in order to identify to the positive points and the possible imperfections that need to be readjusted, or to be substituted for the success of the program; a bibliographical study of the main authors of the subject with the purpose to gound the study, necessary base for the good performance of this work; the study made with the reports identifies some readjustments that need to be corrected, that will be suggested in the end of this study. However the work developed for the SEBRAE/RN is of good quality and the identified negative points do not compromise the good performance of the program, but it can delay the success desired; Despite the studied reports being inconsistent in some points, it can be identified significant improvements with the result of the work developed for the SEBRAE/RN, among others the creation of financial alternatives for the agriculturists who deal with the beekeeping, the employment, income and development of the enterprising capacity of the producers. However, is verified that it would have to exist more efficient ways that made possible a bigger interaction among the managers of the program and the participant public so that the continuous and necessary improvements were made to any well guided project

O estudo teve como objetivo comparar a eficácia do mel e do açúcar mascavo na cicatrização de feridas induzidas cirurgicamente na pele de cobaias, para avaliar o tempo de cicatrização, as variações macroscópicas e microscópicas do tecido cicatricial, a contração das feridas e o grau de contaminação. Quinze cobaias da raça Abissínia, machos inteiros, de seis meses de idade e pesando entre 500 a 850 gramas, foram divididas em três grupos com cinco animais cada, nos quais foram induzidas, cirurgicamente, três feridas em cada animal com dimensão de 1,5cm² e distância entre elas de 1,5cm, na região dorsal. A ferida F1 foi tratada diariamente com mel, a ferida F2 com solução salina 0,9% (controle) e a ferida F3 com o açúcar mascavo. A eutanásia foi realizada no Grupo 1 ao sétimo dia após a cirurgia, no Grupo 2 ao décimo quarto dia e no Grupo 3 no vigésimo primeiro dia após a cirurgia, sendo as biópsias encaminhadas para avaliação histopatológica. Foram também realizados swabs das feridas em todos os grupos no terceiro e sétimo dias após a cirurgia e as amostras enviadas para a cultura e isolamento bacteriano. Concluiu-se que as feridas tratadas com o mel cicatrizaram mais rápido em relação às tratadas com o açúcar mascavo, demonstrando a maior propriedade cicatrizante do mel em relação ao açúcar mascavo.
