Os medicamentos usados no tratamento da osteoporose podem interferir no reparo ósseo de fraturas. O objetivo deste trabalho foi avaliar o efeito do Risedronato (1,5mg/kg/dia) e do medicamento homeopático Calcarea fluorica 6CH (3 gotas/dia) no reparo ósseo em ratas com osteopenia induzida. Para isso, 105 ratas foram submetidas à ovariectomia e 35 ratas à cirurgia sham. Através da histomorfometria, foi avaliada a porcentagem de preenchimento com osso neoformado na área total disponível compreendendo o defeito e a cavidade medular e também a porcentagem de osso trabecular dentro da área preenchida pelo calo ósseo aos seis, 12, 18 e 24 dias de tratamento (n=6). Em relação à área de preenchimento total, o grupo R superou os valores dos demais (p<0,05) enquanto que os grupos Cf e O se mostraram com valores iguais em todos os períodos de tempo, diferindo somente aos seis dias, quando o grupo Cf foi superior ao O. A porcentagem de área trabecular dentro da área preenchida pelo calo aos seis, 12 e 18 dias não foi diferente entre os grupos R, Cf e O. Aos 24 dias o grupo O apresentou os maiores valores de área trabecular, sendo diferente do grupo R, com os menores valores, e o grupo Cf mostrou valores intermediários. Concluiu-se que a ovariectomia interferiu de forma prejudicial no reparo e que o medicamento risedronato foi o que estimulou a maior formação óssea e a menor remodelação. A Calcarea fluorica 6CH estimulou maior formação óssea nas fases iniciais da reparação quando comparada ao grupo O, mas não interferiu negativamente na remodelação. / The increase in life expectancy is associated with a higher incidence of degenerative diseases such as osteopenia and osteoporosis, which elevate the occurrence of bone fractures, and demand long treatment. The medication used to treat osteoporosis can interfere with bone fractures repair. The aim of this work was evaluating the effects of Risedronate (1,5mg/Kg/day) and of the homeopathic medicine Calcarea fluorica 6CH (3 drops/day) on bone repair in rats with induced osteopenia. For that, 105 rats were ovariectomized and 35 were sham operated. After 35 days, 2,5 mm monocortical bone lesions were drilled on all animals tibiae. Then, treatment began. Data were submitted to ANOVA and Tukey (5%) tests. According to optical density analysis, there were no differences between treatments at three, six and 12 days, but at 18 and 24 days, group R showed the highest values (p<0,05). Histomorphometric analysis evaluated the filling percentage by newly formed bone within the total area available in the defect and medullar cavity together; and also the percentage of trabecular bone within the callus. According to the first measure, the group R showed the highest values in all periods, surpassing all the groups (p<0,05) while the groups Cf and O showed similar results in all periods, except on day 6, when group Cf was higher. The measure of the trabecular area in the callus showed no difference between the groups R, Cf and O on the 6th, 12th and 18th days. On the 24th day, group O showed the higher trabecular value and group R showed the lower value. It was possible to conclude that ovariectomy has interfered negatively on the bone repair process and that Risedronate stimulated a great amount of bone formation with low bone turn over. Calcarea fluorica 6CH stimulated high bone formation at the initial stages of bone repair when compared to the control group but didn't inhibit bone remodelation.

Ethnomedical and Biomedical Health Care and Healing Practices Among the Rathwa Adivasi of Kadipani Village, Gujarat State, India

Karnyski, Margaret A 06 May 2009 (has links)
The Rathwa of Kadipani village are adivasi (original inhabitants, tribe) residing in a rural part of Gujarat State, India. Primarily farmers, the Rathwa live in an area where development-related projects, such as mineral mining and damming on the Narmada River, are increasingly impacting their livelihood, health status, and quality of life. The local economy is impacted by uncertainty regarding access to water from the Narmada River, concerns related to the extraction of minerals from a mine in Kadipani, and economic issues that arise when the primary wage earner of the household becomes ill. This dissertation addresses Rathwa health care practices, relying primarily on social constructivism and a political economy framework. I also discuss feminist theory when I analyze women, health care, and spirituality, and modernization theory when I consider the impact of development on health. This study examines the intersection of ethnomedical health care practices (e.g., indigenous/folk medicine/faith healing, Ayurveda and homeopathy) with biomedical/allopathic health care practices. The pluralistic health care system available to the Rathwa in both Kadipani and Kawant villages offers services from private and public sectors, resulting in individuals and families in search of treatment frequently accessing multiple health care providers of both the ethnomedical and/or biomedical categories simultaneously. Treatments for illness may include a visit to a Bhoua (faith healer), a public clinic provided by the government, and home remedies prepared from locally available medicinal plants. This junction of ethnomedical and biomedical health care practices impacts family health care seeking behavior and decision making in a number of ways. With a variety of health care providers available, people will go from one provider to the next until they receive the treatment they are requesting (e.g., antibiotics, injections, etc.), or their symptoms dissipate and they are healed. This practice may result in conflict with certain aspects of Rathwa history, tradition, and cultural practices, such as forgoing a visit to the indigenous healer, a practice which is considered part of Rathwa tradition, and going straight to the public clinic for prescription medications, or giving birth in the public hospital instead of using a traditional birth attendant at home.

Thus we tested two vaccines, a biotherapy homeopathicvaccine and other recombinantallopathic vaccine,using mycobacteria in their formulations that were subsequently tested in mice and cattle. In order to study the prophylactic effect of homeopathic vaccine and the potency to be used as a vaccine, we used a model of immunizations and infections. To this end, we used mice female of BALB / c lineage which were distributed in 15 groups of three animals each. To assess the possible immune mechanisms involved in homeopathic biotherapy vaccinations we used Mycobacterium massiliense. The biotherapics were prepared from mycobacterial M. massiliense. After infections and immunizations, the animals were euthanized and their livers and spleens were harvested, macerated, homogenized, plated and incubated at 37 ° C for five days. Then we did the counting of colony forming units (CFU) of bacteria recovered from organs and according to the results obtained were selected the potencies11cH and 19cH to be tested as vaccine, because they have shown more homogeneous results. In the animals that were immunized with 19 cHthere were induction of IgG2a class antibodies specific to M. massiliense similar to (0.18 ± 0.07) infections alone (0.19 ± .02). To assess allopathic vaccine protection was used mycobacterium (Mycobacterium smegmatis mc2155 with PLA71/Fusion) in cattle. After allopathic vaccinations, blood was collected and serum was removed for ELISA test. Animals that received the recombinant live vaccine expressing protein of fusion showed greater levels of specific antibodies (p <0.01). This study evaluated the effect ofhomeopathic biotherapy vaccine composed of M. massiliense and allopathicvaccine formulated with M.smegmatis recombinant in different animal models, thus concluding that both vaccines and vaccines homeopathic and allopathic using different kinds of mycobacteria can induce humoral immune response in an animal model. / O desenvolvimento de novas vacinas no controle de várias doenças na bovinocultura vem incrementando a comercialização de animais e produtos de origem animal. Com isso testaram-se duas vacinas, uma vacina bioterápica homeopática e outra vacina alopática recombinante, utilizando micobacterias em suas formulações que posteriormente foram testadas em camundongos e bovinos. Com o objetivo de estudar o efeito profilático da vacina homeopática e a potência a ser utilizada como vacina, foi empregado um modelo de imunizações e infecções. Para tal, utilizou-se camundongos fêmeas da linhagem BALB/c as quais foram distribuídas em 15 grupos com três animais cada. Para avaliar os possíveis mecanismos imunológicos envolvidos nas vacinações bioterápicas homeopáticas utilizou-se Mycobacterium massiliense. Os bioterápicos foram preparados a partir de micobactérias M. massiliense. Após as imunizações e infecções, os animais foram eutanaziados e deles colheram-se os fígados e baços, os quais foram macerados, homogeneizados, plaqueados e incubados a 37ºC durante 5 dias. Em seguida, fez-se a contagem de unidades formadoras de colônias (UFC) das bactérias recuperadas dos órgãos e de acordo com os resultados obtidos foram selecionadas as potências 11cH e 19cH para serem testadas como vacina, por apresentarem resultados mais homogêneos. Nos animais imunizados com 19 cH houve indução da produção de anticorpos da classe IgG2a específicos para M. massiliense semelhantes à (0,18 ± 0,07) infecção sozinha (0,19 ± 0,02). Para avaliar a proteção da vacina alopática, foi utilizada a micobactéria (Mycobacterium smegmatis mc2155 com PLA71/Fusão), em bovinos. Após as vacinações alopáticas foi coletado sangue e retirou-se o soro para o teste de ELISA. Animais que receberam a vacina viva recombinante expressando a proteína de fusão apresentaram níveis maiores de anticorpos específicos (p< 0,01). Com este estudo avaliou-se os efeitos da vacina bioterápica homeopática composta de M. massiliense e de vacina alopática formulada com M. smegmatis recombinante em diferentes modelos animais, concluindo assim que tanto as vacinas homeopáticas e vacinas alopáticas usando diferentes tipos de micobactérias podem induzir resposta imune humoral em modelo animal.

"A interface entre a homeopatia e a biomedicina: o ponto de vista dos profissionais de saúde não homeopatas" / The interface between homeopathy and biomedicine: the point of view of the non homeopathic professionals

Salles, Sandra Abrahão Chaim 09 August 2006 (has links)
Esse estudo tem como objetivo conhecer as características da relação entre a medicina Homepática e a Biomédica enqua nto partícipes de um campo institucional comum, identificando o movimento de aproximação e afastamento entre homeopatas e médicos da biomedicina e identificando os elementos de caráter ideológico, cultural e técnico-cientifico que fazem parte desse processo, segundo o ponto de vista dos profissionais não homeopatas. Por meio de levantamento da atual situação da Homeopatia no campo da saúde no Brasil, identificam-se os municípios com serviços de homeopatia na rede SUS e as faculdades de medicina que desenvolvem atividades relacionadas à homeopatia. Foram selecionados para a pesquisa os municípios com maior produção ambulatorial de consultas homeopáticas de janeiro a novembro de 2003 (Datasus) e entre as faculdades aquelas de reconhecida relevância na formação médica. Foram entrevistados 48 profissionais de saúde (apenas dois não médicos), sendo 20 docentes/pesquisadores de 11 faculdades de medicina, 16 gestores e 12 médicos que trabalham na rede publica em 6 municípios de cinco estados e do Distrito Federal. As análises foram feitas tendo como categorias de referência as concepções de campo social e cientifico de Bourdieu, as concepções de racionalidades médicas de Madel Luz e os conceitos de modelos ou arranjos tecnológicos do trabalho em saúde de Mendes-Gonçalves, de formação de identidade profissional de médico e ideologia ocupacional de Donnangelo e Schraiber. Foram descritos e analisados através dos depoimentos dos entrevistados: os aspectos considerados facilitadores da aproximação entre as duas medicinas, os que dificultam a ampliação da presença da Homeopatia no campo da saúde, as diferentes formas de apresentação das resistências e as suas concepções sobre a Homeopatia. Entre outros, os resultados apontaram que a 6 legitimação profissional, a construção do SUS e a crise da biomedicina são condições favorecedoras da presença da Homeopatia nas instituições. Mas essas condições não garantem espaços de ensino ou assistência, e as iniciativas dos homeopatas ainda dependem de simpatias locais. Os entrevistados valorizam aspectos da pratica homeopática que recuperam a ideologia ocupacional associada ao ideal de boa prática médica: abordagem integral do paciente, a recuperação da dimensão humanística da medicina e os resultados que obtém ao resolver agravos para os quais os recursos da biomedicina são inadequados ou insuficientes. Facilitam a aproximação com a Academia o interesse no desafio cientifico que representa encontrar novos modelos de pesquisa para explicar, comprovar ou medir a ação da homeopatia e a inclusão de ambientes extrahospitalares como locais de ensino. Dificultam essa aproximação as resistências ao desconhecido e as dificuldades de compreender, com a visão da racionalidade cientifica moderna, a lógica em que a homeopatia opera. Uma outra forma de resistência é considerar a Homeopatia uma medicina apenas para agravos simples e banais, caracterizando-a como uma medicina insegura. O isolamento dos homeopatas e a falta de divulgação da sua cultura foram referidos como razões que mantém o desconhecimento sobre a Homeopatia. Os entrevistados defendem que aceitar os limites de cada medicina e buscar a complementaridade pode levar ao respeito à pluralidade das medicinas, necessária para dar conta de responder à complexidade presente no campo da saúde. / The objective of this study is to access the characteristics of the relationship between homeopathic medicine and biomedicine as both participants of an interinstitucional common field, identifying the approximation and distance movements between homeopathic physicians and biomedicine physicians and identifying the elements of an ideological, cultural and technical-scientific features that are part of this process, according to the non homeopathic professionals’ point of view. The municipalities with homeopathic assistance in the public network of services (SUS) and the medical schools that develop activities related to homeopathy are identified through a survey focusing the current situation of homeopathy in the health field in Brazil. The municipalities with greater clinic production of homeopathic consultations from January to November 2003 (Datasus) and the most recognized schools, as being of major relevance to the medical education, were selected. Forty eight health professionals were interviewed (only two were not physicians), of whom 20 professors of 11 medical schools, 16 managers and 12 physicians that work in the public assistance network in 6 municipalities of five states and the Federal District. The analysis was carried out using as reference categories Bourdieu’s conceptions of social and scientific field, Madel Luz’s conception of medical rationality, Mendes-Gonçalves’ concepts of models or technological arrangements of the health work, Donnangelo and Schraiber’s conceptions of professionals’ identity formation and occupational ideology. The discourses of the interviewed professionals were described and analyzed taking 8 into consideration: the aspects considered facilitators of the approximation between the two medicines; the ones that make difficult the expansion of the homeopathy presence in the health field; presentation forms of resistance; and the professionals’ conceptions of homeopathy. Among others, the results of the study pointed out, as facilitating conditions for the presence of Homeopathy in institutions, he professional legitimation, the construction of the Universal Health System (SUS) and the biomedicine crises. However, these conditions do not guarantee teaching or assistance spaces, and the homeopathy related initiatives still depend on local sympathies. The interviewed professionals valorize aspects of the homeopathic practice that recover the occupational ideology associated to the ideal of good medical practice: integral approach of the patient, the recovering of the humanistic dimension of medicine and the results that are obtained when solving a health problem in occasions when biomedicine’s resources are inadequate or insufficient. The approximation with the academic field is facilitated by the interest in the scientific challenge that represents the encounter of new research models to explain, proof or measure homeopathy’s actions and the inclusion of extra hospital ambiences as teaching places. This approximation is made difficult by the resistance to the unknown and the difficulties of comprehension of the logic in witch homeopathy operates, difficulties related to modern science’s view on rationality. Another form of resistance is to considerate homeopathy as a medicine directed only to simple and minor health problems, characterizing it as an insecure medicine. The isolation of homeopathic professionals and the little divulgation of their culture were mentioned as reasons that sustain the lack of knowledge on Homeopathy. The interviewed professionals defend the acceptation of each medicine’s limits and the searching for complementarities that can lead to respecting the plurality of medicines, conditions that are necessary to formulate an answer to the present state of complexity in the health field.
