Macrophage activity regulation by high dilution of aspirin and its possible mechanism

Under LPS-stimulus, platelets can activate macrophagesby a cell-to-cell contact or through cytokine degranulation. Rebound effects of anti-thrombotic agents, such as prostanoids and COX inhibitors can lead to thrombosis, infarct, and stroke. Aspirin has been prescribed for decades due to its powerful antiplatelet action, but it is also related to paradoxical effects such as withdrawal syndrome peaks, resistance, and thrombogenesis. Ultra-diluted aspirin can also produce the same effect in one hour, regardless of Cox-2, by still unknown pathways. Antithrombotic effects of aspirin are also reversed by its high dilutions.Aims: This study aims to characterize the effects of aspirin 15cH on macrophages challenged with LPS, a Cox-2 activator.Methodology: RAW 264.7 macrophages were sown in 24 wells plates using R10medium, boosted with 1µg/ml LPS,and treated with aspirin 15 cH and controls. The activity was evaluated after 24 hours. Supernatants were evaluated for cytokines, nitric oxide, and dielectric oscillations, through solvatochromic dyes (Cartwright's method).Results and discussion: macrophage spreading was increased by aspirin 15 cH, anLPS-like effect. Paradoxically, a significant reduction of this effect was noted when both, LPS and aspirin 15 cH, were added. Succussed water reversed the effect of LPS, leading to TNF (p<0.05) production close to baseline levels. Also, the single treatment with succussed water inhibited IL-10 production (p<0.05), but aspirin 200 µg/mL (positive control) highly increased it (p<0.0001), showing the validity of the model. Nitric oxide production was strengthened by LPS presence (p<0.0001), as expected, but partially downregulated after treatment with aspirin 200 µg/mL, water and succussed water. A pilot study with solvatochromic dyes showed no significant difference among treatments.Conclusion: The main data suggest that aspirin 15 cH increases macrophage activity but presents a paradoxal effect when mixed with LPS. On the other hand, succussed water itself has modulatory effects on macrophages.

Homeopathy treatment of Malassezia Pachydermatis in vitro

A common clinical occurrence in dogs is otitis externa caused by excessive growth of yeasts Malassezia pachydermatis, which can become chronic after wrong treatments, in which microbial resistance can occur. Homeopathic remedies can be considered a successful alternative, selecting the medicine through the similitude principle. Herein, 50 µL of a 1:1000 dilution of Malassezia pachydermatis suspension at 0.5 McFarland scale was used to seed the yeast into Sabouraud dextrose agar plates using a Drigalski spreader to proceed with colony unit counting. Before being seeded, the yeast suspensions were treated with 1% of different homeopathic treatments previously selected from a pilot study, which means Sulphur 6cH, Dolichos pruriens 6cH, and Kali carbonicum 6cH, being water, and succussed water used as controls. For comparison, a set of Sabouraud dextrose agar plates containing 1% Tween 80 was seeded in parallel. The treatments were made blind and evaluated in triplicate. Contaminated cultures were withdrawn. The number of colonies per plate was assessed, and smears were made from the cultures to classify yeast growth according to cytomorphology on ImageJ®software. The preliminary results show no significant effect of all tested medicines compared to the controls. High data variability was also observed, mainly in those cultures whose medium was prepared with Twin 80. In conclusion, at this point of the study, no evidence of the effects of the studied medicines on Malassezia pachydermatis growth in vitro could be identified. The analysis of cytomorphology is still in course.

Homeopathy and high dilutions in the context of water structure research: the experience in the 9thWorld Water Forum ­2022

Water plays a vital role in adapting natural and human systems in a climate change scenario. Understandinghow this fundamental element of life is organized and functioning is essentialtogather, disseminate, and advanceknowledge about water at the micro and nanostructure level. With developments in the different research areas, the International Panel on Water Structure­IPWS was created during the 8thWorld Water Forum(WWF)inBrasília,2018,to connect researchersspecialized inwater structure under aninterdisciplinary perspective.In 2020 a partnership between CIRAT ­International Center on Water and Transdisciplinarityand WATER­a Multidisciplinary Research Journalhasbegun, intendedto organize a special edition on Water and Transdisciplinarityto be launched during the 9thWWF, in Dakar, on March 24th, 2022, in response to the challenges of our century, with the aim to disclose advanced knowledge about water at different structural levels, leading to a new understanding of it.The whole project was organized by Prof. Leoni Bonamin, from UniversityPaulista, with the support of the Editor-in-Chief Prof. Gerald Pollack, from Washington University at Seattle. The focus was on the cross-over of information with technical quality and bold thinking, as shown in Figure 1 below.Homeopathy wasincludedamong the themes.Aftera multi-step process, in which manuscripts were received (after personal invitationssent to more than 200 researchers in the field)andevaluated in a two-step peer review processto ensure maximum scientific understanding, the result showed a set of innovative contributions in which authors were allowed to be bold in their projects while careful with the methodology. Theentire process was carried out voluntarily by all the actors involved.Thus, the whole editorial process was philanthropic, there were no costs for the authors, and all articles were published as open access. Authors from five countries participated in this project: Brazil, India, Italy, Russia, and the United States. Different sessions were organized according to the topics: "Opinion Article," "Hypotheses," "Water Structure," "High Dilutions," "Water and Environment," and "New Devices."Fiveof twelve articles reported results on high dilutions, including its physicochemical propertiesandthe implications on biological systems, such as plants and aquatic animals [1-4]. This initiative inspired all to envision the possibility of offering practical solutions to old problems involving different ways of water management, which couldreduce social gaps and improve the quality of life fairly and universally.

Avaliação da atividade biológica de preparações homeopáticas de antiadiponectina em camundongos submetidos a dieta hipercalórica / Biological activity of homeopathic preparations of adiponectin in mice subjected to a hypercaloric diet

A adiponectina foi originalmente identificada como uma proteína expressa e produzida por adipócitos do tecido gorduroso abdominal de várias espécies animais, cuja função é manter a homeostase do tecido adiposo em relação às demandas energéticas do corpo. Preparações homeopáticas de substâncias endógenas são capazes de modular diferentes funções celulares. Neste projeto, buscou-se conhecer os possíveis efeitos de uma preparação homeopática de anticorpos antiadiponectina no controle do depósito adiposo subcutâneo abdominal, utilizandose modelo experimental. Quarenta camundongos Swiss machos adultos oram divididos em um grupo experimental e 3 controles. Os animais foram alimentados durante 1 mês e 7 dias com suplemento dietético comercial e tratados simultaneamente, por via oral, com antiadiponectina 6cH. Foi avaliado o ganho de peso corporal, bem como características macro e microscópicas do tecido adiposo subcutâneo e do fígado. Os resultados mostraram discreta redução no ganho de peso e redução estatisticamente significativa no diâmetro dos adipócitos no grupo experimental. Não foram observadas alterações inflamatórias ou degenerativas significativas no fígado. Os mecanismos envolvidos nestas alterações metabólicas precisam ser pesquisados em estudos futuros. (AU)

Adiponectin was originally identified as a protein expressed and produced by the abdominal fat adipocytes of several animal species which function is to maintain the homeostasis of the adipose tissue vis-à-vis the body energy demands. Homeopathic preparations of endogenous substances are able to modulate several cell functions. In the present study we investigated possible effects of a homeopathic preparation of anti-adiponectin antibodies on the control of the abdominal fat by means of an experimental model. Forty Swiss male adult mice were fed a commercial dietary supplement for 1 month and 7 days and treated with anti-adiponectin 6cH per oral route. Parameters assessed were weight gain and macro- and microscopic characteristics of the subcutaneous adipose tissue and liver. The experimental group exhibited slightly less weight gain and statistically significant reduction of the adipocyte diameter. We did not detect significant inflammatory or degenerative changes in the liver. The mechanisms involved in the detected changes need to be investigated in future studies. (AU)
