Structural and thermal analyses of zinc and lactose in homeopathic triturated systems.

BACKGROUND: A series of different experimental approaches was applied in Zincum metallicum (Zinc met.) samples and lactose controls. Experiments were designed to elucidate the effect of zinc trituration and dynamization on physicochemical properties of homeopathic formulations, using lactose as excipient. METHODS: Zinc met. potencies (Zinc met 1-3c) were triturated and dynamized using lactose as excipient, according to Brazilian Homeopathic Pharmacopoeia. Lactose samples (LAC 1-3c) were also prepared following the same protocol and used as controls. The samples were analyzed structurally by Atomic Absorption Spectroscopy (AAS), X-ray Diffraction (XRD), Transmission Electron Microscopy (TEM) with Energy Dispersive X-ray Spectroscopy (EDX) and Scanning Electron Microscopy (SEM), and thermodynamically by Thermogravimetry (TG) and Differential Scanning Calorimetry (DSC). RESULTS: AAS analysis detected 97.0 % of zinc in the raw material, 0.75 % (Zinc met 1c) and 0.02% (Zinc met 2c). XRD analysis showed that inter-atomic crystalline spacing of lactose was not modified by dynamization. Amorphous and crystalline lactose spheres and particles, respectively, were observed by TEM in all samples, with mean size from 200 to 800 nm. EDX obtained with TEM identified zinc presence throughout the amorphous matter but individualized zinc particles were not observed. SEM images obtained from dynamized samples (LAC 1c and Zinc met 1c) with electron backscattering could not identify zinc metal grains. The dynamization process induced Derivatives of Thermal Gravimetric (DTg) peak modification, which was previously centered near 158°C to lactose, to a range from 140 to 170°C, suggesting the dynamization process modifies the temperature range of water aggregation. Thermal phenomena were analyzed and visualized by Analysis of Variance (ANOVA) and Principal Component Analysis (PCA) statistics. Both indicated that fusion enthalpy of dynamized samples (DynLAC 1-3c; DynZn 1-3c) increased 30.68 J/g in comparison to non-dynamized lactose (LAC; p < 0.05). CONCLUSIONS: Our results suggested no structural changes due to the trituration and dynamization process. However, TG and DSC analyses permit the differentiation of dynamized and non-dynamized groups, suggesting the dynamization process induced a significant increase in the degradation heat. These results call for further calorimetric studies with other homeopathic dilutions and other methodologies, to better understand the dynamics of these systems.

Homeopathic medicines for prevention of influenza and acute respiratory tract infections in children: blind, randomized, placebo-controlled clinical trial.

BACKGROUND: Influenza and its complications are common at all ages, especially in children. Vaccines and anti-influenza drugs aim to prevent it. Preventative approaches with favorable risk profiles should be considered for flu, particularly since the evidence of the efficacy of anti-viral drugs is debated. METHODS: This pragmatic clinical trial was conducted in the Brazilian Public Health System in Petrópolis (BPHSP) with children aged from 1 to 5 years old. The medications used were mainly selected based on in vitro experiments (InfluBio), and in successful qualitative clinical experiences (Homeopathic Complex). Following informed parental consent, subjects were randomly distributed, in a blind manner, to three experimental groups: Homeopathic Complex, Placebo, and InfluBio. BPHSP health agents collected flu and acute respiratory infection symptomatic episodes monthly following the established protocol. The number of these episodes was registered in one year (2009-2010). RESULTS: Out of the 600 children recruited, 445 (74.17%) completed the study (149: Homeopathic complex; 151: Placebo; 145: InfluBio). The number of flu and acute respiratory infection symptomatic episodes detected in this clinical trial was low; however, it was different between homeopathic groups and placebo (p < 0.001). In the first year post-intervention, 46/151 (30.5%) of children in the placebo group developed 3 or more flu and acute respiratory infection episodes, while there was no episode in the group of 149 children who used Homeopathic Complex, and only 1 episode in the group of 145 (1%) children who received InfluBio. CONCLUSION: These results suggested that the use of homeopathic medicines minimized the number of flu and acute respiratory infection symptomatic episodes in children, signalizing that the homeopathic prophylactic potential should be investigated in further studies.

Homeopathic medicine of Melissa officinalis combined or not with Phytolacca decandra in the treatment of possible sleep bruxism in children: A crossover randomized triple-blinded controlled clinical trial.

PURPOSE: The present randomized controlled clinical trial evaluated the efficacy of homeopathic medicines of Melissa officinalis (MO), Phytolacca decandra (PD), and the combination of both in the treatment of possible sleep bruxism (SB) in children. STUDY DESIGN: Patients (n = 52) (6.62 ± 1.79 years old) were selected based on the parents report of SB. The study comprised a crossover design that included 4 phases of 30-day treatment (Placebo; MO 12c; PD 12c; and MO 12c + PD 12c), with a wash-out period of 15 days between treatments. METHODS: At baseline and after each phase, the Visual Analogic Scale (VAS) was used as the primary outcome measure to evaluate the influence of treatments on the reduction of SB. The following additional outcome measures were used: a children's sleep diary with parent's/guardian's perceptions of their children's sleep quality, the trait of anxiety scale (TAS) to identify changes in children's anxiety profile, and side effects reports. Data were analyzed by ANOVA with repeated measures followed by Post Hoc LSD test. RESULTS: Significant reduction of SB was observed in VAS after the use of Placebo (-1.72 ± 0.29), MO (-2.36 ± 0.36), PD (-1.44 ± 0.28) and MO + PD (-2.21 ± 0.30) compared to baseline (4.91 ± 1.87). MO showed better results compared to PD (p = 0.018) and Placebo (p = 0.050), and similar result compared to MO+PD (p = 0.724). The sleep diary results and TAS results were not influenced by any of the treatments. No side effects were observed after treatments. CONCLUSION: MO showed promising results in the treatment of possible sleep bruxism in children, while the association of PD did not improve MO results.

Heteroisotherapics effect on the treatment against smoking: a cognitive-behavioral approach

The most common way of consuming nicotine is in tobacco cigarettes. Nicotine causes intense addiction. The National Cancer Institute coordinates and executes the Tobacco Control Program in Brazil, through actions that encourage the adoption of healthier lifestyles. In this context, homeopathy has used Heteroisotherapic medicines formulated according to the homeopathic pharmaceutical technology with scientific evidence of efficacy in the detoxification of substances and metals, and in the desensitization of foods or medicines. Aims Promote the importance of the cognitive-behavioral approach in combination with the homeopathic treatment against smoking. Methodology In the initial phase of the randomized double-blind clinical study (CEP / HUCFF / UFRJ 65622916.2.0000.5257), the effectiveness of the 6CH heteroisotherapeutic drug was assessed. Volunteers were recruited andin-person welcoming meetings, using the cognitive-behavioral approach, were carried out to inform them about the risks of smoking and the benefits of quitting. In addition, they were supported and guided during the smoking cessation process so that they could deal with the withdrawal syndrome, the psychological dependence and the constraints associated with smoking. Results and discussion84 participants were selected according to the inclusion criteria, and divided by randomization into two groups:the Test Group (heteroisotherapeutic medication) and the Control Group (homeopathic medication Nux vomica6CH).Both groups will be followed for 12 months. The combination of the following approaches has led to a significant increase in the cessation rate: I.Prepare the smoker for solving his own issues; II. Stimulate skills to resist temptations to smoke; III. Prepare to prevent relapse; IV. Prepare to deal with stress. Studies show that, regardless the duration of these approaches, there is an increase in the abstinence rate. Moreover, the longer the total approach time (frequency multiplied by the time spent on each contact), the higher the abstinence rate. On the other hand, from a total approach time of 90 minutes on, there is no further increase in the abstinence rate. ConclusionThe partial results obtained so far demonstrate that the cognitive-behavioral approach played a decisive role in the groups performance, favoring the treatment adherence as well as the group cohesion around the Project's objective, contributing to the effectiveness of the medicine, a decreased anxiety, improved sleep, cessation or decrease in the number of cigarettes smoked per day and the abstinence rate.

Bioterápicos de Candida albicans induzem alterações nos índices de adesão e na respiração celular / Biotherapics of Candida albicans induce changes in the levels of adhesion and in cellular respiration

Introdução: O gênero Candida spp é responsável por cerca de 80% das infecções fúngicas no ambiente hospitalar e constitui causa relevante de infecções sistêmicas em pacientes hospitalizados, especialmente em doentes graves e em imunocomprometidos, com predominância da Candida albicans. A adesão das leveduras às células epiteliais do hospedeiro é um potente estimulador para a formação de hifas, forma invasiva do fungo [1]. Os bioterápicos são medicamentos preparados a partir de produtos biológicos, elaborados conforme a Farmacopeia Homeopática Brasileira (FHB)[2], indicados para tratamento de infecções de etiologia conhecida, empregados com grande sucesso no tratamento clínico destas infecções. Os bioterápicos RC, desenvolvidos pelo médico brasileiro Roberto Costa (RC) são preparados a partir do agente etiológico íntegro e, segundo suas pesquisas, possuem maior capacidade de estimular o sistema imunológico do hospedeiro.

Avaliação do potencial genotóxico e mutagênico de soluções homeopáticas de Candida albicans / Evaluation of the genotoxic and mutagenic potentials of homeopathic Candida albicans solutions

ntrodução: Candida spp é encontrada naturalmente na microbiota natural da pele humana, trato gastrointestinal e genitourinário e, em geral, até 75% da população não apresenta qualquer sintoma [1]. No entanto, a candidíase oral é muito comum entre os pacientes HIV e pacientes submetidos à quimioterapia. O tratamento da candidíase oral é necessário, uma vez que a doença provoca desconforto e disfagia, resultando em má nutrição, recuperação lenta e internação prolongada [2,3]. Os resultados preliminares obtidos pelo nosso grupo com um novo bioterápico preparado a partir de Candida albicans (Candida 30x) mostrou um grande potencial para reduzir a taxa de adesão da candida quando células epiteliais foram pré-tratadas. Este estudo está sendo desenvolvido visando avaliação do potencial mutagênico e genotóxico de várias soluções homeopáticas.Objetivos: O objetivo deste estudo foi avaliar o potencial genotóxico e mutagênico de diferentes potências homeopáticas do medicamento de C. albicans. Metodologia: Uma parte de C. albicans obtida do sangue de pacientes brasileiros [4] foi diluída em 9 partes de água estéril. Esta amostra foi submetida a 100 sucussões mecânicas (aproximadamente 3 Hz), usando Autic ®, originando a primeira diluição (1x). Em seguida, 1 ml desta solução foi diluída em 9 ml de solvente, submetida a 100 sucussões, obtendo a potência 2x. Este procedimento foi repetido sucessivamente para obter a potência de 30x, de acordo com a Farmacopéia Homeopática Brasileira [5]. Pela mesma técnica, o veículo foi preparado até 30x para ser usado como controle. Todas as amostras foram preparadas em condições estéreis e assépticas, utilizando-se gabine de fluxo laminar, classe II, e foram armazenados em geladeira (8ºC). As amostras 1x, 6x, 12x, 18x 24x, 30x de C. albicans e 30x de água (controle do veículo) foram analisadas por: Induteste, que avalia a capacidade de agentes físicos ou químicos em promover a indução lisogênica em reflexo a danos em moléculas de DNA de bactérias lisogênicas. E o Teste de Ames, que utiliza linhagens indicadoras de Salmonella typhimurium, sensíveis a substâncias que podem induzir diferentes tipos de mutação.Int J High Dilution Res 2011; 10(36):177-179Proceedings of the XXV GIRI Symposium and VIII CBFH; 2011 Sep 04-07; Foz do Iguaçu (Brazil)179Resultados: De acordo com o Induteste, não houve diminuição da fração de sobrevivência de bactérias e aumento na formação de centros infecciosos, independentemente da potência homeopática testada. O mesmo perfil foi obtido após o Teste de Ames, com resultados semelhantes ao controle negativo. Conclusão: Podemos concluir que estas amostras não são capazes de induzir danos ao DNA bacteriano das cepas utilizadas. Assim, a utilização deste medicamento não apresenta quaisquer efeitos secundários relacionados com a mutagênese e genotoxicidade.(AU)

Background: Candida spp is naturally found in humans? flora of skin, gastrointestinal and genitourinary tracts and, in general, up to 75% of the population does not have any symptom [1]. However, oral candidiasis is very common among HIV patients and patients undergoing chemotherapy. The treatment of oral candidiasis is necessary once the disease causes discomfort and dysphagia, resulting in poor nutrition, slow recovery, and prolonged hospital stay [2,3]. Preliminary results obtained by our group with a new biotherapic prepared from Candida albicans (Candida 30x) showed a great potential to reduce the candida yeast adhesion rate when the epithelial cells were pre-treated. This study is currently being developed with the evaluation of mutagenic and genotoxic potentials of several homeopathic solutions. Aims: The goal of this study was to assess the genotoxic and mutagenic potentials of different homeopathic potencies of C. albicans. Methodology: One part of C. albicans yeast obtained from Brazilian patient?s blood [4] was diluted in 9 parts of sterile water. This sample was submitted to 100 mechanical succussions (approximately 3 Hz), using Autic® Brazilian machine, originating the first dilution (1x). Then, 1 ml of this solution was diluted in 9 ml of solvent, submitted to 100 succussions, obtaining 2x potency. This procedure was successively repeated to obtain 30x potency, according to Brazilian Homeopathic Pharmacopoeia [5]. By the same technique, water vehicle was prepared until 30x to be used as control. All samples were prepared in sterile and aseptic conditions, using laminar flow cabinet, class II and were stored in the refrigerator (8ºC). The samples 1x, 6x, 12x, 18x, 24x and 30x of C. albicans and water 30x (vehicle control) were analysed by: the Inductest, which assesses the ability of physical or chemical agents to promote lysogenic induction as a reflection of damage in DNA molecules in lysogenic bacteria, and the Ames test, which uses indicator strains of Salmonella typhimurium, sensitive to substances that can induce different types of mutation. Results: In the Inductest no decrease in survival fraction of bacteria and no increase in the formation of lysogenic induction were detected independently of the homeopathic potency employed. The same profile was obtained after the Ames test, with similar results to negative control. Conclusion: Afterwards, we can conclude that these samples are not able to induce DNA damage in the cells tested. So, the use of this medicine does not present any side effects related to mutagenesis and genotoxicity.(AU)

Estabilidade Físico-Química e Microbiológica do Bioterápico Candida albicans RC em Variadas Potências / Physical-chemical and microbiological stability of biotherapy Candida albicans RC in different potencies

Oral Candidiasis is an opportunist fungal infection, with high incidence in HIV and immunosuppressed patients and Candida albicans is the most common causing agent. In some cases, it can evolve to resistant injuries to antifungal conventional therapy. According to Brazilian Homeopathic Pharmacopeia (BHP) [1], biotherapic medicines are prepared from chemically undefined biological products. Biotherapics created by Brazilian doctor Roberto Costa (RC) have a different homeopathic compounding technique, as its dynamization starts from the ethiologic agent of the illness in its alive form, which present higher capability to stimulate the host immunological system [2,3].Further experiments are being carried out in order to confirm the preliminary data obtained.(AU)

O uso da homeopatia para prevenir sintomas da gripe humana e infecção respiratória aguda: um estudo clínico duplo cego, randomizado, placebo controlado com 600 crianças do Serviço Público de Sáude do Brasil / The use of homeopathy to prevent symptoms of human flu and acute respiratory infections: a double-blind, randomized, placebo-controlled clinical trial with 600 children from Brazilian Public Health Service

In Brazil, homeopathy was implemented in the Public Health Service through the National Policy on Complementary and Integrative Practices of the Health Ministry, published in 2006. Homeopathy appears as a very interesting therapy to be used in the Public Health Services since its medicines are compounded at a very low cost. Considering this interesting scenario to develop research in the Public Health, the Family Health Program (FHP) in Petropolis and the Faculty of Pharmacy at UFRJ started a partnership with the Roberto Costa Institute.(AU)

No Brasil, a homeopatia foi implementada no Serviço Público de Saúde, através da Política Nacional de Práticas Integrativas e Complementares do Ministério da Saúde, publicada em 2006. A homeopatia surge como uma terapia muito interessante para ser usada no serviço público de saúde uma vez que seus medicamentos tem um custo muito baixo. Considerando este cenário interessante para desenvolver uma pesquisa em Saúde Pública, o Programa de Saúde da Família (PSF) de Petrópolis e a Faculdade de Farmácia da UFRJ iniciaram uma parceria com o Instituto Roberto Costa.

Preparada pelo método cinqüenta milesimal (lm) / Evaluación físico-química y citotóxica de soluciones altamente diluídas de Euphorbia tirucalli L. preparadas por el método homeopático cincuenta milesimal (LM)

Motivação: Embora Hahnemann tenha descrito o método LM na 6ª. Edição do Organon da Arte de Curar, poucas pesquisas tem sido feitas sobre as propriedades físico-químicas destas preparações. Além disso, ainda não existem evidências que apontem para a correlação entre propriedades físico-químicas e os efeitos biológicos das altas diluições. Objetivos: determinar características físico-químicas das preparações LM tais como condutividade elétrica, pH e índice de refração, bem como o efeito biológico em modelos experimentais. Materiais e Métodos: foi analisada uma série de diluições desde 1 lm até 10 lm de Euphorbia tirucalli L., preparada a partir do látex e do suco da planta. Para considerar as características sazonais desta planta, usamos 2 populações diferentes, colhidas uma em Junho de 2007 e outra em Maio de 2008. Além disso, o efeito citotóxico da Euphorbia tirucalli L. 5 lm foi testado em células humanas cancerosas (MCF7) através de ensaio MTT. Conclusões: Algumas diferenças entre as duas populações foram observadas. No entanto, nenhuma correlação clara pode ser observada entre as propriedades físico-químicas e a atividade biológica.

Background: although Hahnemann described the fifty-milesimal (LM) method in the 6th edition of the Organon of the Medical Art, very little research has been carried out on the physical chemical properties of these homeopathic preparations. Furthermore, there is still no evidence allowing for the correlation between the alleged physical chemical properties and the biological effects of high dilutions. Aims: to evaluate physical chemical characteristics of LM preparations including electrical conductivity, pH and refraction index, and their effect on biological experimental models. Materials and methods: preparations tested for physical chemical analysis were dilutions 1 lm to 10 lm of Euphorbia tirucalli L. prepared from the latex and the juice of the plant. To rule the seasonal characteristics of this plant, 2 different populations were used, one collected in June 2007 and the other in May 2008. Furthermore, the cytotoxic effect of Euphorbia tirucalli 5 lm was tested on human breast cancer cells (MCF7) through MTT assay. Conclusions: Some differences among the two collections were observed. However, any clear correlation could be observed between physical chemical properties and biological activity.

Motivación: Aunque Hahnemann describió el métodocincuenta milesimal (LM) en la 6 ª edición del Organon del Arte Médica, muy poca investigación se ha realizado sobre las propiedades físico-químicas de estos preparados homeopáticos. Por otra parte, todavía no hay pruebas que permitan la correlación entre las presuntas propiedades físico-químicas y los efectos biológicos, de las altas diluciones. Objetivos: evaluar las características físico-químicas de los preparados LM, incluyendo conductividad eléctrica, pH y el índice de refracción, y su efecto en modelos biológicos experimentales. Materiales y métodos: las muestras para el análisis físico-químico fueron diluciones 1 a 10 lm de Euphorbia tirucalli L. preparadas a partir del látex y el jugo de la planta. Para descartar las características sazonales de esta planta, dos poblaciones diferentes fueron utilizadas, una recogida en junio de 2007 y otro en mayo de 2008. Además, el efecto citotóxico de Euphorbia tirucalli 5 lm fue probado en células humanas de cáncer de mama (MCF7) a través del ensayo MTT. Conclusiones: Algunas diferencias entre las dos colecciones se observaron. Sin embargo, ninguna correlación clara se observó entre las propiedades físicas- químicas y actividad biológica.
