Tratamiento de hipertrigliceridemia con terapia botánica y fibratos

Debido al aumento que ha venido presentado la práctica de la medicina tradicional en los últimos años, la OMS presenta en el 2003 la estrategia sobre la práctica de la medicina tradicional a los países en los cuales este tipo de medicina es más frecuente año tras año. Las plantas se han ido clasificando y han recibido denominación botánica, también han sido químicamente analizadas para poder distinguir sus componentes y diferenciar sus principios activos. Los Fibratos son fármacos utilizados ampliamente en la práctica clínica para la regulación de los lípidos y reducción del riesgo cardiovascular. A ellos se les atribuye una disminución promedio en los niveles de triglicéridos del 36%.

¿Pluralismo o colonialidad médica? Un estudio alrededor del cáncer en diferentes sistemas médicos colombianos

En esta investigación se realiza un análisis del tipo de relaciones que se establecen entre la medicina alopática y la medicina indígena yagecera en el escenario urbano de Bogotá. Para ello, toma distancia de los estudios ya realizados sobre este tema en el campo de la antropología a partir de dos aspectos: en primer lugar, busca acercarse a esta relación a partir de las trayectorias profesionales de un conjunto de médicos (tanto indígenas como alopáticos); en segundo lugar, se aproxima a estas relaciones a partir de una enfermedad particular: el cáncer.

La energía vital-Qi

La Medicina Tradicional China (MTC en adelante), contempla algo que en la mirada positivista (de algunas comunidades de occidente), ha pasado completamente inadvertido, el Qi (se pronuncia chi). Para la MTC todo cuanto hay en el universo es Qi, tanto la corriente de bioelectricidad que constituye el cuerpo, la estructura material de un hueso o de otros tejidos o las emociones que generan pensamientos/sentimientos.

Desenvolvimento e validação de método analítico para quantificação da boldina em peumus boldus mol. (monimiaceae) e avaliação preliminar de sua estabilidade

Peumus boldus Molina (Monimiaceae) é uma árvore comum e abundante no Chile, e suas folhas são amplamente empregadas pela medicina tradicional para o tratamento de uma variedade de afecções do sistema digestivo e hepatobiliar. Seus principais constituintes químicos são alcalóides do tipo aporfínicos, sendo a boldina seu maior e mais característico representante, cujas propriedades antioxidantes são extensivamente relatadas na literatura, servindo desta forma como marcador químico para a espécie. Com o objetivo de contribuir com parâmetros de controle de qualidade, um estudo botânico macro e microscópico das folhas e do pó da espécie foi realizado. Características morfológicas, identificadas pela análise macroscópica, como pilosidade, tipologia dos tricomas, proeminência ao redor da base dos tricomas e aparência do bordo, e características microscópicas como estômatos anomocíticos, folha hipoestomática e ocorrência de cristais de oxalato de cálcio denotam valor taxonômico. Parâmetros farmacopéicos como cinzas totais e perda por dessecação foram determinados, e um método de quantificação da boldina foi desenvolvido e validado utilizando a CLAE. O limite mínimo de boldina observado na análise de 10 amostras adquiridas foi de aproximadamente 0,016%. A fim de avaliarse o comportamento de seus constituintes químicos frente a variações de temperatura e umidade, realizou-se estudo de estabilidade acelerada (40ºC ± 2ºC / 75% ± 5% U.R.). A degradação máxima de boldina foi observada após 90 dias em câmara climática chegando a aproximadamente 52%. A reação de degradação sugerida foi de segunda ordem, e o tempo de vida útil e meia-vida calculados foram de aproximadamente 18 dias e 165 dias, respectivamente. Por fim, realizou-se a quantificação de alguns metais pesados nas folhas da espécie, que decresceram na ordem de Fe> Mn> Cu> Ni, sendo que Pb, Cr e Co tiveram níveis abaixo do limite de detecção de 5 μg/g.

Efeito de um extrato de Artemísia Vulgaris L. marcação in vitro de constituintes sanguíneos com tecnécio-99m em ratos wistar

Artemisia vulgaris L..is used in folk medicine and in Traditional Chinese Medicine (TCM). This medicinal plant has been utilized as anticonvulsive, analgesic, antispasmodic effect, rheumatic pains, menstrual dyspepsia, asthenia, epilepsy, hepatitis, fevers, anemia and to expel parasites. In nuclear medicine, blood constituents are labeled with technetium-99m (99mTc) and used as radiopharmaceuticals (radiobiocomplexes). Authors have been described that synthetic and/or natural drugs could modify the labeling of blood constituents with 99mTc. The aim of this work was to evaluate the effects of an aqueous extract of Artemisia vulgaris L. on the labeling of blood constituents with 99mTc. Blood samples withdrawn of Wistar rats were incubated with Artemisia vulgaris L, stannous chloride and 99mTc, as pertechnetate ion. Aliquots of plasma (P) and blood cells (BC) were isolated. Aliquots of P and BC were also precipitated with trichloroacetic acid and soluble (SF) and insoluble (IF) fractions were separated. The radioactivity in each fraction was counted and the percentages of radioactivity (%ATI) were calculated. Artemisia vulgaris L. extract decreased significantly (p<0.05) the %ATI on BC and on IF-BC. The analysis of the results indicates that the extract could have substances that could interfere on the transport of stannous through the erythrocyte membrane altering the labeling of blood cells with 99mTc. Working in this study was a multidisciplinary group, with Phisical therapists, Biomedicals, Physicals, Pharmacists, Biologists, Statistics and Physicians.

Currently one of the biggest problems faced for the industry of phytopharmaceuticals with regard to the quality of raw materials is the microbial contamination. The aim this study was to evaluate the antimicrobial action of the hidroalcoholic extract of aroeira, beyond testing the effectiveness of the preservative system in hidrogel to the base of this extract. The extracts were prepared by maceration in the ratio of 1:10 of solvent plant/with alcohol 40%. The methods for microbial count were pour plate and test for specific microorganisms, analyzing in third copy each one of the samples. The antimicrobial activity of aroeira extracts was performed using an agar diffusion method, using strains of S. aureus, P. aeruginosa, E. coli, B. subtilis, C. albicans, C. tropicalis, C. krusei, C. guilliermondii, T. rubrum, M. gypseum, A. flavus and A. niger. The formula with aroeira was evaluated by the challenge test. This method consisted of artificial contamination the sample with separate inóculos of A. niger, C. albicans, E. coli e S. aureus aeruginosa and determinations of survivors for the method of counting for pour plate , during times 0, 24h, 48h, 7 days, 14 days, 21 days and 28 days. How much to the results, one verified that the extract of aroeira in the 13,5 concentration mg/mL presented antimicrobial activity for cepas of E. coli, B. subtilis, P. aeruginosa e S. aureus, producing inhibition zone, on average with 13 mm of diameter. However it did not present no fungi activity. The formula with aroeira containig both methylparaben and propylparaben showed a good efficacy in challenge test front to strains of A. niger, C. albicans, E. coli, S. aureus. The A criteria of European Pharmacopoeia, adopted in this work, was verified that this product revealed the good preservative efficacy for the challenge test, time interval of the 28 days. However, it is interesting to extend this study, in order to carry through the sped up stability and the test of shelf, to establish the validity of this formularization

Caracterização e quantificação de marcadores químicos do extrato hidroetanólico das folhas de Kalanchoe brasiliensis Cambess

Kalanchoe brasiliensis Cambess (Crassulaceae), commonly known as saião , coirama branca , folha grossa , is originally from Brazil and commonly found in São Paulo to Bahia, mainly in the coastal zone. Regarding of biological activities, most preclinical studies were found in the literature, mainly about the anti-inflammatory activity of extracts obtained from leaves and / or aerial parts of K. brasiliensis. As regards the chemical constitution, it has been reported mainly the presence of flavonoids in the leaves of the species, but until this moment did not knows which are the active compounds. Although it is a species widely used in traditional medicine in Brazil, there is no monograph about the quality parameters of the plant drug. In this context, this study aims to characterize and quantify the chemical markers of hydroethanolic extract (HE) from the leaves of K. brasiliensis, which can be used in quality control of plant drug and derivatives obtained from this species. The methodology was divided into two parts: i. Phytochemical study: to fractionate, isolate and characterizate of the chemical (s) marker (s) of the HE from the leaves of K. brasiliensis; ii. To Developed validate of analytical method by High Performance Liquid Chromatography (HPLC)-diode array detector (DAD) to quantify the chemical (s) marker (s) of the EH. i. The EH 50% was prepared by turbo extraction method. It was then submitted to liquid-liquid partition, obtaining dichloromethane, n-butanol and ethyl acetate (AcOEt) fractions. The AcOEt fraction was selected to continue the fractionation process, because it has a chemical profile rich in flavonoids. The acOEt fraction was submitted to column chromatography using different systems for obtaining the compound Kb1. To identify this compound, it was submitted to UV analysis ii. For quantitative analysis, the EH was analyzed by HPLC, using different methods. After selecting the most appropriate method, which showed satisfactory resolution and symmetrical peaks, it was validated according to parameters in the RE 899/2003. As result, it was obtained from the AcOEt fraction the compound Kb1 (2.7 mg). Until this moment, the basic nucleus was characterized by UV analysis using shift reagents. The partial chemical structure of the compound Kb1 was identified as a flavonol, containing hydroxyls in 3 , 4 position (ring A), 5 and 7 free (ring B) and a replacement of the C3 hydroxyl by a sugar. As the analysis were performed in the HPLC coupled to a DAD, we observed that the UV spectrum of the major peaks of EH from K. brasiliensis shown similar UV spectrum. According to the literature, it has been reported the presence of patuletin glycosydes derivatives in the leaves of this species. Therefore, it is suggested that the compound Kb1 is glycosylated patuletin derivative. Probably the sugar (s) unit(s) are linked in the C3 in the C ring. . Regarding the development of HPLC analytical method, the system used consists of phase A: water: formic acid (99,7:0,3, v / v) and phase B: methanol: formic acid (99,7:0,3, v / v), elution gradient of 40% B - 58% B in 50 minutes, ccolumn (Hichrom ®) C18 (250x4, 0 mm, 5 μm), flow rate 0.8 mL / min, UV detection at 370 nm, temperature 25 ° C. In the analysis performed with the co-injection of thecompound Kb1 + HE of K. brasiliensis was observed that it is one of the major compounds with a retention time of 12.47 minutes and had a content of 15.3% in EH of leaves from K. brasiliensis. The method proved to be linear, precise, accurate and reproducible. According to these results, it was observed that compound Kb1 can be used as a chemical marker of EH from leaves of K. brasiliensis, to assist in quality control of drug plant and its derivatives

Práticas populares de cuidado à criança: o saber/fazer de cuidadoras

Popular practices correspond to the resources used by households, lay people and popular therapists, whose perception of knowledge is constructed in the everyday. In this context, the sick child can become vulnerable to be dependent on a family caregiver, who often decide to employ popular practices. Thus, the child care should be shared between carer and health professional. However, they know little about the resources that the family uses to detect a grievance in infant. Therefore, the present research aimed to analyse the use of popular practices by caregivers of children with zero to five years old. We conducted an exploratory and descriptive study with a qualitative approach, together with 15 caregivers of children who were treated at the Joint Unit Felipe Shrimp, located in Natal, Rio Grande do Norte, Brazil. To select the participants, they should be age and above 18 years; be caregivers of children up to five years of age; and reside in the area ascribed the Joint Unit Felipe Shrimp. The data collection took place between September and October 2013, through in depth interview. This step was preceded by the approval of the Health Department of the city of Natal; the direction of the Joint Unit Felipe Shrimp; as well as, the Committee on Ethics in Research from the Federal University of Rio Grande do Norte with Certificate of Presentation and Consideration Ethics, No 15467013.8.0000.5537. Furthermore, the interviewees formally authorized their participation in the research by signing the consent form. The data were treated according to the technique of content analysis in the form of thematic analysis according to Bardin. This process, four categories emerged: "Types of popular practices used in the care of the child"; "Source of information of popular practices"; "Results obtained with popular practices"; "Factors that hinder the adoption of common practices." The results showed the use of popular practices by caregivers in the case of illness to children such as the homemade preparations with medicinal plants and folk healers. The family environment was referenced as the main learning space and spread of popular practices, which are influenced by cultural relations present in this context. As to the results obtained with popular features, the caregivers said to be satisfactory, and this triggers a feeling of confidence and acceptability of such measures. It is concluded that the use of popular practices in child care persists in everyday most of the participants, despite the hegemony of allopathic therapy. The caregivers stated that such practices are effective and easy to obtain, being secured in context by popular culture. In addition, health professionals, especially nurses, were seldom mentioned by the caregivers as to the information concerning popular resources used by them, which suggests the weakness in dialogic process of negotiating practices between both of them
