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.

Comparative analysis for quality control of mother tinctures in Brazilian reports

Quality control of ahomeopathic mother tincture begins with the analysis of the raw material. Once the product is obtained, some organoleptic characteristics and Physicochemical properties such as appearance, colour, odour, density, dry residue, alcohol content,and chemicalmarker are evaluated. In Brazil, mother tinctures from different suppliers may have high variability in terms of the specifications described in the homeopathic pharmacopoeia. Objective: The aim of the present study was to compare mother tinctures' quality control from different pharmaceutical suppliers based on Brazilian Homeopathic Pharmacopoeia 3rd edition. Methods: Five mother tinctures were selected according to the high number of requests in the pharmacies, also its monographs are in the Brazilian Homeopathic Pharmacopoeia (FHB) 3rd edition. The report of analysis of the product was provided by three homeopathic pharmacies from the city of Rio de Janeiro. The information in the reports wasevaluated and compared to its monograph. Results and discussion: In this study, it was found that the number of laboratories that provide homeopathic pharmaceutical ingredients is rather low. In addition, in some reports, a number of identification tests werenot described properly when compared to the monograph. Besides that, some information diverges from the pharmacopoeia, for example, absence of dry residue testing, replacement of the part of the plant used to prepare the mother tincture,and results that do not meet pharmacopoeia specifications. As can be seen, the quality and effectiveness of homeopathic medicines prepared from these tinctures may be compromised. Conclusion:In order to guarantee consumer protection and the quality and effectiveness of medicines, governments and regulatory agencies should requirea greater commitment from suppliers in the production of homeopathic inputs.

The third group will be the homeopathic medicine in association with itraconazole. The fourth will be the treatment with itraconazole only. And the last group will be the fungi with dynamized distilled water 30DH. Sporothrix brasiliensis30DHwill be prepared according to Brazilian Homeopathic Pharmacopeia. Results and discussions: The experiments are still in progress and the results will be analyzed through Analysis of variance (ANOVA) to determine statistically significant differences. Previous articles based on biotherapic treatments demonstrated successful results, so our research group is conducting these experiments to evaluate the effect in this model. Conclusion: Experiments will be made to verify the efficacy of biotherapic on sporotrichosis treatments.

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)

Tratamento com bioterápico Candida albicans influencia a adesão de fungos a células Ma104 in vitro / Treatment with Candida albicans biotherapic influences in vitro fungal adhesion to Ma-104 cells

Oral candidiasis is an opportunist fungal infection in humans, mainly caused by Candida albicans. It occurs when the host presents an imbalance in the immune system and Candida spp., normally found in human flora, become able to develop the infection [1]. This disease is very common in HIV patients, and in all individuals that present immunossupression, such as patients treated with chemotherapy. Considering this scenario, the development of new medicines to treat oral candidiasis is mandatory.These results showed that the biotherapic did not present any citotoxicity, but was able to modify the morphological aspects of Ma-104 cells. Additionally, the interaction between host cells and ethilogic agent is directly influenced by biotherapic treatment, suggesting a promising antifungal potential of this medicine.(AU)

High dilutions of Euphorbia tirucalli L. (aveloz) modify the viability and glycolytic metabolism of cell lines / Altas diluições de Euphorbia tirucalli L. (aveloz) modificam a viabilidade e o metabolismo glicolítico de linhas celulares

The latex of Euphorbia tirucalli L. (Aveloz) is popularly used to treat cancers from diverse sources such as: breast, prostate, lung and kidney. Furthermore, high dilutions of this latex (latex-HDs) have been successfully used in the treatment of tumors, although the mechanisms involved in this antitumoral activity are not yet known [...] Latex-HDs were obtained through the interaction of two procedures: 1:100 dilution in mass and agitation, using 2 solvents, water and 70% ethanol in homeopathic preparations 5, 15 and 30cH, following the Brazilian Homeopathic Pharmacopeia. Cell lines were incubated with 1 % and 10 % of latex-HDs for 24 hours. Controls treated with similar preparations without latex were incubated under the same conditions. Cell viability was analyzed by MTT assay and morphological features were assessed by May-Grunwald-Giemsa method. Cell ultrastructure was analyzed by transmission electron microscopy. Metabolic alterations were detected by spectrophotometric assay for the enzyme 6-phosphofructo-1-kinase (PFK-1) activity. 1% of ethanolic latex-HDs induced no alterations in MelanA cells viability, however Aveloz 15cH induced an increase in MCF7 cells viability. After aqueous treatment, MelanA cells viability decreased in almost all systems, whereas in MCF7 cells, an increase was detected in dynamized water systems and Aveloz 15CH. However, only water 15cH increased cell viability in comparison to control and non-dynamized water. No alterations in MCF7 morphology and ultrastructure were visualized through light microscopy or electronic microscopy, respectively. Interesting results were detected when we studied the glycolytic metabolism of both cells, giving support to evidences showing that HDs interfere in the metabolism of cell lines. Further studies are needed to better understand the mechanisms involved in this in vitro biological response to HDs.

Além do mais, altas diluições desse látex (latex-HDs) têm sido utilizadas com sucesso no tratamento de tumores, embora o mecanismo dessa ação ainda seja desconhecido [...] As látex-HDs foram obtidas através de 2 procedimentos: diluição 1:100 em massa e agitação, com 2 solventes, água e etanol 70%, nas diluições homeopáticas 5, 15cH e 30cH de acordo com a Farmacopéia Homeopática Brasileira. As linhas celulares foram incubadas com látex-HDs 1% e 10% por 24 horas. Foram preparados controles similares sem o látex e incubados sob as mesmas condições. A viabilidade celular foi analisada através do método May-grunwald-Giemsa. A ultrastrutura celular foi analisada através de microscopia eletrônica de transmissão. As alterações metabólicas foram detectadas por ensaio de espectrofotometria para a atividade da enzima 6-fosfofructo-1-quinase (PFK-1). Látex-Hds em etanol 1% não induziram qualquer alteração na viabilidade das células MelanA, mas Aveloz 15cH induziu aumento da viabilidade das células MCF7. Após tratamento, a viabilidade das células MelanA diminuiu em quase todos os sistemas, enquanto que nas células MCF7 foi detectado aumento nos sistemas aquosos e Aveloz 15cH, mas só água 15cH aumentou a viabilidade celular por comparação ao controle e água não dinamizada. Não foram detectadas alterações na morfologia celular por microscopis de luz quando se estudou o metabolismo glicolítico em ambas as células, demonstrando que os padrões de resposta celular dependem do tipo de solvente, metabolismo celular e procedimento de diluição. Esta é a primeira vez que se mostra que as altas diluições interferem no metabolismo de linhas celulares. Outros estudos são necessários para se compreender melhor os mecanismos envolvidos nesta resposta in vitro a altas diluições de aveloz.

Chronic toxicological effects of high diluted solutions of Aveloz (Euphorbia tirucalli L. ) on healthy mice: a preliminary study / Efeitos toxicológicos crônicos de altas diluições de Aveloz (Euphorbia tirucalli L. ) em camundongos sadios: estudo preliminar

The latex extracted from Euphorbia tirucalli, a plant popularly known as Aveloz, is used in complementary medicine to induce tumor regression. However, as this latex has toxic effects when administered orally in ponderal doses, the present study was designed to assess the effects of high dilutions in healthy mice over a period of 18 weeks. The Aveloz latex-high diluted solutions (latex-HD) were obtained through the interaction of two processes: 1:100 dilution in mass and succussion, using ethanol 70% as a solvent, in the homeopathic dilutions of 5, 15 and 30cH, following Farmacopéia Homeopática Brasileira. Control solutions without latex were compounded (ethanolic-HD) in the same dilutions and were administered simultaneously. The animals which received latex-HD 30cH showed a significant increase in food consumption (p < 0.05) without significant difference in weight gain. In regards to water consumption, no statistical difference was shown when different Aveloz latex-HD groups were compared, apart from the group that received 1 drop of pure latex in water, which presented a significant increase (p < 0.05) in this parameter.
