Since human beings have sought in nature, components that can obtain help in therapeutics or even in the cure of diseases. The progress made in the area of science promoted the development of recognized and effective herbal medicines, as well as the search for the population, for less aggressive treatments. The evaluation of the antioxidant activity of plants has been an important issue taking into account its importance on human health, since the natural antioxidants present a reduced health risk, when compared to the synthetic ones that present toxic effect. From the Asteraceae family, of which the plant species Taraxacum officinale, popularly known as dandelion, stands out among the 71 species on the list of the Ministry of Health (RENISUS), scientifically affirmed, to treat liver disorders, inflammations, potential in the anti-bacterial, cytotoxic, antiviral, antiparasitic, antifungal activity, besides studies to verify its anticancer action and of carcinogenic prevention. The acute toxicity of Taraxacum officinale appears to be low, with LD50 values estimated at 36.8g / kg and 28.8g / kg, for the whole plant. The adverse or complex toxic effects for T. officinale have not yet been reported. This review of the literature was elaborated through studies of articles contained in the Scielo, Google Scholar and Pub Med platforms. Through this review the importance of phytotherapy studies for pharmacological purposes was verified, aiming to improve the therapeutics.
Objetivos: identificar o nível de conhecimento sobre a Saúde do Homem, analisar as repercussões deste conhecimento para a prevenção de riscos e agravos à saúde da população masculina e discutir as implicações para a prevenção de riscos e agravos à saúde da masculina e para a prática assistencial no nível Técnico em Enfermagem. Método: Foram entrevistados 103 indivíduos de ambos os sexos. Foram selecionados 88 questionários, 14 foram descartados por terem sido preenchidos incorretamente e 01 entrevistado recusou-se participar da pesquisa. Resultados: Houve predominância feminina (55,6%), faixa etária variou de 15 a 59, a média etária 20,2 e mediana 24 anos. Escolaridade variou do ensino fundamental à pós-graduação. Conclui-se que a comunidade apresenta baixo nível de conhecimento sobre a PNAISH, boa parte sequer sabia da sua existência. Sinalizando a necessidade de difusão da mesma, bem como dos seus objetivos. Conclusão: Nossa intenção é que as lacunas do conhecimento aqui evidenciadas sejam preenchidas para que tenhamos uma comunidade participativa no tocante à prevenção de riscos e agravos à saúde da população masculina. Descritores: Enfermagem, Cuidado de Enfermagem, Saúde do Homem.
The use of natural products as medicines has been growing in the entire world. There are concerns that these products may contain potentially toxic ingredients and contaminants such as heavy metals. The labeling of blood constituents with technetium-99m has been influenced by the presence of natural extracts. We evaluated the influence of a chayotte (Sechium edule) extract (100% v/v macerated) on the labeling of blood elements with 99mTc. The animals were treated with the extract during 15 days. Samples of blood were carried out with specific blood biochemistry kits. The present study analyzed the influence ofchayotte in the survival of the strain of Escherichia coli AB1157 submitted to reactive oxygen species induced by stannous chloride. There was a reduction of the lethal effect induced by stannous chloride on the survival of the E. coli culture in the presence of chayotte. The results indicated a decrease in the level of glucose and globulin The effect of the extract could be explained by its metabolic transformation inducing the generation of oxidant metabolites. The culture of bacteria when was treated with stannous chloride and chayotte simultaneously, the extract could be reacting with stannous chloride ions, protecting them against the oxidation avoiding the generation of reactive oxygen species.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
