Highly diluted medication reduces tissue parasitism and inflammation in mice infected by Trypanosoma cruzi.

AIM: To evaluate the effects of Kalium causticum, Conium maculatum, and Lycopodium clavatum 13cH in mice infected by Trypanosoma cruzi. MATERIALS AND METHODS: In a blind, controlled, randomized study, 102 male Swiss mice, 8 weeks old, were inoculated with 1400 trypomastigotes of the Y strain of T. cruzi and distributed into the following groups: CI (treated with 7% hydroalcoholic solution), Ca (treated with Kalium causticum 13cH), Co (treated with Conium maculatum 13cH), and Ly (treated with Lycopodium clavatum 13cH). The treatments were performed 48 h before and 48, 96, and 144 h after infection. The medication was repertorized and prepared in 13cH, according to Brazilian Homeopathic Pharmacopoeia. The following parameters were evaluated: infectivity, prepatent period, parasitemia peak, total parasitemia, tissue tropism, inflammatory infiltrate, and survival. Statistical analysis was conduced considering 5% of significance. RESULTS: The prepatent period was greater in the Ly group than in the CI group (p = 0.02). The number of trypomastigotes on the 8th day after infection was lower in the Ca group than in the CI group (p < 0.05). Total parasitemia was significantly lower in the Ca, Co, and Ly groups than in the CI group. On the 12th day after infection, the Ca, Co, and Ly groups had fewer nests and amastigotes/nest in the heart than the CI group (p < 0.05). Decreases in the number of nests and amastigotes in the intestine were observed in the Ly group compared with the CI group (p < 0.05). In the liver (day 12), Ly significantly prevented the formation of inflammatory foci compared with the other groups. In skeletal muscle, Co and Ly decreased the formation of inflammatory foci compared with CI (p < 0.05). Ly afforded greater animal survival compared with CI, Ca, and Co (p < 0.05). The animals in the Co group died prematurely compared with the CI group (p = 0.03). CONCLUSIONS: Ly with 13cH potency had significantly more benefits in the treatment of mice infected with T. cruzi, reducing the number of blood parasites, amastigote nests in tissue, and the number of amastigotes per nest and increasing animal survival.

Bioterápico 200 DH causa redução do parasitismo cerebral em camundongos infectados com Toxoplasma gondii / Biotherapic 200 DH reduces cerebral parasitism in mice infected with Toxoplasma gondii

Toxoplasmosis is a zoonosis that represents a serious public health problem, worldwide distributed. Pregnant women are part of the most risky group due to congenital sequels. The necessity of a preventive treatment for congenital infections is of great importance [1] Biotherapics, highly diluted medicines prepared with T. gondii according to the Brazilian Homeopathic Pharmacopoeia [2], is an important prevention strategy, ensuring a safe and cheap approach to protozoan infections [3]. However, little is known about the effects of different potencies and treatment schedules.The highly diluted biotherapic 200DH T. gondii caused mortality in one animal in group however caused no significant difference other clinical and parasitological parameters evaluated although there was a decrease of parasitism brain of mice infected with the protozoan compared to control group.(AU)

Bioterápico 17DH T. cruzi em uso prolongado melhora clinicamente camundongos infectados pelo Trypanosoma cruzi / Biotherapic T. cruzi 17DH when continuously used clinically improves mice infected with Trypanosoma cruzi.

Introduction: In Trypanosoma cruzi infection, the pathogenesis is the result of a rupture in the host - parasite relationship [1]. This rupture is related to the imbalance of the vital force of the host, expressed through signs and symptoms, defined by Hahnemann (1995)[2] as being the source of the disease. There is no research in the literature about the clinical evolution of mice experimentally infected with T. cruzi and treated in different ways using biotherapic. Therefore, this is an area to be studied in the future.Conclusion: The use of biotherapic T. cruzi 17DH for a long period causes clinical improvement of the infected mice with Trypanosoma cruzi. The clinical use of these results in human beings should consider the allometric medicine dosage which takes into account the metabolic rate of each organism(AU)

Introdução: Na infecção pelo Trypanosoma cruzi, a patogenia é resultado do rompimento do equilíbrio da relação parasito - hospedeiro (Tafuri, 1987), que está relacionada com o desequilíbrio da força vital do hospedeiro, expressando-se através de sinais e sintomas, definido por Hahnemann (2007), como sendo a origem da doença. Não existe na literatura trabalhos que abordem a evolução clínica de camundongos experimentalmente infectados pelo T. cruzi e tratados com diferentes esquemas de tratamento utilizando bioterápico. Sendo assim, é necessária a realização de estudos com este objetivo.Conclusão: O uso prolongado do bioterápico 17DH T. cruzi melhora clinicamente camundongos infectados pelo T. cruzi. A utilização clínica destes resultados em humanos, deve considerar o sistema alométrico de dosagem de medicamentos que leva em conta a taxa metabólica de cada organismo.(AU)

Bioterápico 17DH de Trypanosoma cruzi diminui alterações histopatológicas em camundongos infectados pelo protozoário / Biotherapic of Trypanosoma cruzi 17x controlled histopathological alterations in mice infected by this protozoon

Introduction: about 10 million people worldwide suffer from Chagas? disease [1]. The World Health Organization (WHO) has explicitly acknowledged the significance of this condition and supports the use of Complementary and Alternative Medicine by health systems integrated with conventional treatments. Even so, one century after its discovery it still represents a global challenge [1,2]. Biotherapics are ultradiluted medicines and the infection of mice by Trypanosoma cruzi is an excellent model to understand their effect [3,4]. At 8 weeks, mice are physiologically more developed than at age 4 weeks, including a more competent immune system [5].Conclusion: there is a difference in the effect of the ultradiluted medicine between mice 4- and 8-week old. Eight-week old animals treated with biotherapic exhibited lower tissue parasitism, which is the opposite of what was observed in 4-week old animals.(AU)

Qualidade e autenticidade de amostras de chá de camomila (Matricaria recutita L. – Asteraceae) / Quality and authenticity of samples of chamomile tea (Matricaria recutita L. - Asteraceae)

Com o objetivo de avaliar a qualidade dos chás de camomila (Matricaria recutita), comercializadas na cidade de Umuarama-Paraná, essas amostras foram analisadas quanto à autenticidade do produto, características organolépticas, pureza, teor de umidade e cinzas totais, rotulagem e peso médio, em relação aos correspondentes dados indicados no rótulo da embalagem. A presente análise mostrou a presença de taxas de impurezas acima de 5% em 85,7% das amostras de chá em forma de capítulos florais íntegros e em 100% das amostras comercializadas na forma de sachet. O elevado teor de matéria orgânica estranha altera as características organolépticas do chá. Quanto aos descritivos nos rótulos da embalagem dos produtos verificou-se a falta de informações, o qual indica a não conformidade com a legislação vigente. Os dados do presente trabalho mostram que a maioria dos produtos comercializados não se encontrava em concordância com a legislação vigente. Torna-se, portanto, necessária maior assiduidade na ação fiscalizadora dos produtos alimentícios comercializados pela Vigilância Sanitária.
