The protective effect of Canova homeopathic medicine in cyclophosphamide-treated non-human primates

Background: Canova activates macrophages and indirectly induces lymphocyte proliferation. Here we evaluated the effects of Canova in cyclophosphamide-treated non-human primates. Methods: Twelve Cebus apella were evaluated. Four animals were treated with Canova only. Eight animals were treated with two doses of cyclophosphamide (50 mg/kg) and four of these animals received Canova. Body weight, biochemistry and hematologic analyses were performed for 40 days. Micronucleus and comet assays were performed for the evaluation of DNA damage. Results: We observed that cyclophosphamide induced abnormal WBC count in all animals. However, the group treated with cyclophosphamide plus Canova presented a higher leukocyte count than that which received only cyclophosphamide. Cyclophosphamide induced micronucleus and DNA damage in all animals. The frequency of these alterations was significantly lower in the Canova group than in the group without this medicine. Conclusions: Our results demonstrated that Canova treatment minimizes cyclophosphamide myelotoxicity in C. apella. (C) 2012 Elsevier Ltd. All rights reserved.

Homeopathic treatment for bone regeneration: experimental study

Aim and method: The objective of this research was to study the effect of homeopathic treatment with Plumbum metallicum (Plumbum met.) on mandibular bone repair in rats.Materials and methods: We analyzed the mandibles of 60 male rats, approximately 3-month-old, randomly divided into three groups of 20 animals each: control, treated with calcitonin, and treated with a homeopathic medicine. A circumscribed bone defect measuring 4 mm in diameter was made in the mandible and covered with a pollytetrafluorethylene (PTFE) barrier. The group treated with calcitonin received 2 IU/kg intramuscularly three times a week; the group treated with Plumbum met. 30c received three drops in water every day. The animals were sacrificed after 7,14,21 and 28 days. The mandibles were removed and submitted to histologic and histomorphometric analyses.Results: Data were analyzed statistically by two-way ANOVA and by the Tukey test. The interaction effect (ANOVA, F df(6; 48) = 4.64; p = 0.001 < 0.05) indicated that the relationship between treatments was not the same at each time of sacrifice. Although statistical analysis of the histomorphometric data showed a similar results for the treated and control groups. But histological analysis showed complete filling of the surgical defect throughout its extent was only for the group treated with Plumbum met.Conclusion: The study demonstrated that for repair of surgical defects in rat mandibles Plumbum met. 30c and control did not differ significantly in histomorphometric terms.

A randomized controlled trial of homeopathic treatment of weaned piglets in a commercial swine herd

Aim: To evaluate the zootechnic performance and occurrence of diarrhea in piglets in the week post-weaning comparing supplementation with sucrose saline which contained or did not contain added homeopathic medicine.Method. Animals were randomly divided into three groups of 24 piglets each. The control group did not receive any treatment. Another group received sucrose saline, and the third group received sucrose saline with homeopathic medicine added, in the period of zero to seven days post-weaning. The homeopathic treatment consisted of Echinacea angustifolia, Avena sativa, Ignatia amara, Calcarea carbonica, all 6cH. Piglets were weighed daily for weight gain or loss, and observed for diarrhea and feed intake.Results: Animals receiving sucrose saline alone and sucrose saline with homeopathy had less weight loss than control (p = 0.017, p = 0.0001 respectively). There was no statistical difference in relation to overall incidence of diarrhea or food consumption. These data suggest that the supplementation with sucrose saline with added homeopathic medicine in the first seven days post-weaning may be an useful option to reduce weight loss in weaned piglets.

Homeopathic treatment of Arabidopsis thaliana plants infected with Pseudomonas syringae

Homeopathic basic research is still in the screening phase to identify promising model systems that are adapted to the needs and peculiarities of homeopathic medicine and pharmacy. We investigated the potential of a common plant-pathogen system, Arabidopsis thaliana infected with the virulent bacteria Pseudomonas syringae, regarding its response towards a homeopathic treatment. A. thaliana plants were treated with homeopathic preparations before and after infection. Outcome measure was the number of P. syringae bacteria in the leaves of A. thaliana, assessed in randomized and blinded experiments. After a screening of 30 homeopathic preparations, we investigated the effect of Carbo vegetabilis 30x, Magnesium phosphoricum 30x, Nosode 30x, Biplantol (a homeopathic complex remedy), and Biplantol 30x on the infection rate in five or six independent experiments in total. The screening yielded significant effects for four out of 30 tested preparations. In the repeated experimental series, only the homeopathic complex remedy Biplantol induced a significant reduction of the infection rate (p = 0.01; effect size, d = 0.38). None of the other four repeatedly tested preparations (Carbo vegetabilis 30x, Magnesium phosphoricum 30x, Nosode 30x, Biplantol 30x) yielded significant effects in the overall evaluation. This phytopathological model yielded a small to medium effect size and thus might be of interest for homeopathic basic research after further improvement. Compared to Bion (a common SAR inducer used as positive control), the magnitude of the treatment effect of Biplantol was about 50%. Thus, homeopathic formulations might have a potential for the treatment of plant diseases after further optimization. However, the ecological impact should be investigated more closely before widespread application.

Informatics to support patient choice between diverse medical systems

Culturally, philosophically and religiously diverse medical systems including Western medicine, Traditional Chinese Medicine, Ayurvedic Medicine and Homeopathic Medicine, once situated in places and times relatively unconnected from each other, currently co-exist to a point where patients must choose which system to consult. These decisions require comparative analyses, yet the divergence in key underpinning assumptions is so great that comparisons cannot easily be made. However, diverse medical systems can be meaningfully juxtaposed for the purpose of making practical decisions if relevant information is presented appropriately. Information regarding privacy provisions inherent in the typical practice of each medical system is an important element in this juxtaposition. In this paper the information needs of patients making decisions regarding the selection of a medical system are examined.

Integralidade no cuidado nas Medicinas Naturais: a resposta dos usuários ao medicamento homeopático

Inicialmente, este trabalho tece algumas considerações a respeito de apontamentos conceituais teórico-práticos da Homeopatia e fala da construção social da demanda para tal prática, tendo em vista responder ao mal estar difuso que inquieta nossos usuários. A realização de estudos como este que busquem compreender as terapêuticas que incluem as práticas integrativas e complementares no SUS, tal com a Homeopatia, a partir do entendimento sobre sua utilização tanto pelos praticantes como pelos usuários pode contribuir para a pesquisa social sobre essas práticas, visando sua efetiva institucionalização no sistema público de saúde no país. O objetivo deste trabalho foi buscar compreender qual o entendimento de pacientes e de médicos sobre a resposta ao tratamento homeopático, a partir de suas narrativas, visando identificar a existência de relação com os sentidos da integralidade do cuidado. Trata-se de uma pesquisa avaliativa de natureza qualitativa, adotando como informantes-chaves o paciente e o profissional homeopata, e utilizando o prontuário como fonte de informação secundária, com a finalidade de complementar as informações. Como campo de investigação, foram escolhidos três tipos de atendimentos distintos: dois tipos de atendimento realizados em serviços públicos, onde o profissional realiza abordagem exclusivamente homeopática (nos municípios de Juiz de fora e do Rio de Janeiro) e um no PSF de Volta Redonda, no qual o atendimento homeopático está incluído nas atividades do médico de família. Foram realizadas também entrevistas cujas análises foram ordenadas (com relação às narrativas dos entrevistados) em diversas disposições para possibilitar diferentes cortes de análises. Os resultados apresentados são discutidos relacionando-os com as categorias representativas da Integralidade que mais se fizeram presentes, a saber, a Integralidade na dimensão da abordagem total do paciente, a autonomia e o cuidado. Essas categorias nos levam a pensar na possibilidade de apresentarem-se como campos possíveis de serem incluídos em fichas clínicas nas quais o profissional, juntamente com o paciente, seriam convidados a refletir, a cada etapa do tratamento, e a sinalizar em que direção a resposta terapêutica está se dando, registrando suas observações de forma objetiva e contribuindo, desta forma, para a análise e a avaliação da integralidade no tratamento homeopático. As conclusões deste trabalho contribuem no sentido de ampliar as possibilidades de avaliação, dando visibilidade à dimensão integral do tratamento homeopático com todo o seu leque semântico e dialógico evidenciados neste estudo, bem como de proporcionar avanços no processo de institucionalização no sistema público de atendimento à saúde, pois a avaliação enquanto etapa final desse processo ocorre ao se medir seus resultados e conferir-lhe validação. Tal atitude ainda possibilita, ao binômio médico-paciente, uma oportunidade de crítica e de avaliação permanente sobre o processo terapêutico que se está experimentando.

A ciência das doenças e a Arte de curar: trajetória das medicina hipocrática

Este trabalho tem como objeto as trajetórias da medicina hipocrática no pensamento médico ocidental. Através da análise bibliográfica de textos e documentos, objetivou-se compreender como os conceitos de vida e do processo saúde-doença, partindo de uma mesma raiz, foram se definindo em sistemas médicos baseados em paradigmas distintos. Para tanto, inicialmente, procurou-se levantar e analisar o nascimento e desenvolvimento da medicina hipocrática, com ênfase em seu método de observação clínica e em sua proposta terapêutica. Em seguida, foi realizada a análise do histórico e das dimensões das racionalidades médicas homeopatia e biomedicina, avaliando o papel dos conceitos sobre physis, vida e vis medicatrix naturae em cada paradigma. Na abordagem dos referidos conceitos, Canguilhem e Jacob foram os principais apoios teóricos. Conclusões: para a medicina homeopática, tal como para a medicina hipocrática, o adoecer e o curar são processo de equilíbrio e desequilíbrio que fazem parte da vida do ser humano e, por isso, também considerados único e individuais. Hahnemann criou uma terapêutica baseada no reconhecimento da pessoa enferma como um indivíduo único, singular, dotado de capacidade automantenedora e autorrestauradora, levando em conta a ideia de natureza que se manifesta em singularidades plurais a cada momento e, portanto, a prescrição medicamentosa é individualizada e mobilizadora da vis medicatrix naturae. A racionalidade médica homeopática compartilha dos conceitos hipocráticos tanto em sua doutrina, quanto nos seus sistemas diagnóstico e terapêutico. Apesar de a biomedicina ter em suas bases a medicina hipocrática, ao se tornar uma ciência das doenças, não mais compartilhou dos conceitos hipocráticos que permitiriam uma abordagem de saúde positiva e de um enfoque terapêutico baseado no sujeito como um ser único. A homeopatia afirma uma medicina que tem como categoria central de seu paradigma a categoria saúde e não a doença, consideradas fenômenos da vida. A vida, assim valorizada, se colocaria no caminho da Grande Saúde, afirmando-se em seu potencial criativo e capaz de transmutar valores.

Os Medicamentos Homeopáticos em Portugal

A homeopatia rege-se por princípios antagónicos relativamente à medicina clássica. Centra-se no doente e está apoiada em princípios como a cura pelos similares - ‹‹similia similibus curentur››, a utilização de pequenas doses de substância activa e na avaliação do doente como um todo. A introdução desta doutrina em Portugal, veio trazer um novo tipo de abordagem ao modo de tratar um paciente. Criada por Samuel Hahnemann, em 1796, e introduzida em Portugal por Manuel da Silva Passos, em meados dos anos 1830, a homeopatia assume-se como uma das principais medicinas alternativas complementares [MAC]. Apoia-se no rigor da formulação do medicamento, na qualidade das matérias-primas, em processos de diluição e controlo de qualidade descritos em farmacopeias oficiais e, disponíveis em várias formas farmacêuticas; o medicamento homeopático apresenta uma razoável cota de mercado, o que requer legislação adequada. A adopção dos conteúdos da Directiva 2001/83/CE no Decreto-Lei [DL] n.º 176/2006, de 30 de Agosto, permitiu a Portugal inserir-se num mercado com maior liberdade de circulação de produtos homeopáticos, mais seguro e previsível. Ferramentas como os procedimentos administrativos centralizados e descentralizados envolvendo os Estadosmembros da Comissão Europeia [CE] e a introdução de medicamentos homeopáticos via registo simplificado [RS], permitiram a Portugal aproximar-se de países como a Alemanha e França, os mercados mais significativos ao nível europeu.

Determinação de parâmetros de qualidade para formas farmacêuticas homeopáticas

All medicine, whether allopathic or homeopathic, must go through strict quality control, which must ratify their characteristics throughout the period of validity. During the time of preparation and storage, solutions of the drugs are in permanent contact with packaging materials that can release undesirable substances to the solution. Several factors may influence the release of packing materials, and factorial design (FD) is a useful tool for analyzing the phenomenon. The aim of this study was the determination of quality parameters for Homeopathic solid (globules) and liquid (drops) dosage forms. It was carried out analysis in homeopathic globules for weight variation, mechanical strength, and moisture content uniformity. For liquid preparations, standard solutions were prepared from natural rubber bulbs, which were subjected to exhaustive extraction with two ethanol solutions (30 and 70%) in the ultrasonic bath for 20 minutes at 25°C and 50°C in three successive cycles. Studies of transfer have been made within five days, by spectrophotometric analysis in the UV region at 312 nm with λmáx and 323 nm for samples in 70% ethanol and 30% respectively. PH values were analyzed. We also conducted two FD studies, where the first, the three-level variables were solvent (chloroform, ethanol and nhexane), sample mass (30, 60 and 90mg), particle size (large disk, small disk and powder sample). In the second study, the solvent level variables were different ethanolic degrees (EtOH 30%, 70% and pure). The percentage of lending in the solutions was 5.5%, 12.4%, 24.2% and 41% of the total estimated in the reference solution. The values of rate constants of transfer were determined in the order of 0.0134 days-1 and 0.0232 days-1 in absorbance values, the solutions in ethanol at 30% and 70% respectively. These results suggest that the speed of transfer of materials from rubber is affected both by the nature of the vehicle as by the temperature

Brosimum gaudichaudii Trecul (Moraceae): Da planta ao medicamento

The chemical, biological, pharmacological and toxicological study of plants used in medical treatments by different societies around the world has been intensifying over the years, primarily in the search for new herbal, homeopathic or even allopathic medicines. Motivated by this interest, we are investigating some Brazilian plant species, among them a tree, Brosimum gaudichaudii Trecul (Moraceae), found in Brazil's savannah-like prairies and scrub-forest (cerrado) and mesophytic forest. Several extracts have been made and separated into fractions and some compounds have been isolated - principally coumarins - and their respective structures analyzed by spectrophotometric and other methods. By collaborating with researchers in other fields, we have been able to carry out various bioassays and even basic clinical tests, namely: determination of anti-helminthic, anti-microbial, photosensitizing, anticancer and mutagenic activities, toxicological and pathogenic studies, with the aim of discovering a genuinely Brazilian herbal or homeopathic medicine.

Comparative therapeutic use of Risedronate and Calcarea phosphorica - Allopathy versus homeopathy - In bone repair in castrated rats

Osteoporosis, a disease characterized by progressive bone loss, has been the target of several studies in the past few years. It results in a much higher risk for fractures and might cause slower bone lesion healing. The aim of this work was to study the effects of Risedronate (allopathic medicine) and Calcarea phosphorica 6CH (homeopathic medicine) on the repair of bone lesions in male rats with osteoporosis induced by castration. Eighty-four three-month-old rats were used divided into four groups of twenty-one animals each. Three groups where castrated and one group was submitted to Sham surgery. One month later, cortical lesions were made in all animals' tibiae and, after one day, the different experimental treatments began according to the following groups: CR - castrated/Risedronate (1 mg/kg/day); CCp - castrated/ Calcarea phosphorica 6CH (3 drops/day); CP - castrated/placebo and SP - Sham/placebo. The animals were sacrificed at seven, fourteen and twenty-eight days after the beginning of the treatments and had their tibiae removed. Digital radiographs of the tibiae were taken and analyzed in order to evaluate the optical density of the defect area. Then, they were decalcified and processed for histological and histomorphometrical analysis. The data were submitted to ANOVA, and to the Tukey and Dunnett tests (5%). The allopathic and homeopathic treatments led to different bone formation as regards remodeling and maturation aspects. Further research is necessary to access the resistance and quality of the newly formed bone.
