Agronomo - Universidade de Taubate, Faculdade CantareiraMiudo, nao mais que meio metro, solitario as vezes, mas espalhado em varias regioes do pais. De suas raizes exala um aroma nao muito comum entre as plantas, que lembra o medicamento Gelol. Essas sao caracteristicas do "gelolzinho", de nome cientifico Polygala sp, da familia Polygalaceae. Em Santo Antonio do Pinhal, o "gelolzinho" e encontrado em pequenas quantidades. Muitos da regiao conhecem a planta por causa do aroma, usando-o como anti-inflamatorio e anestesico em contusoes. A principal substancia responsavel pelo seu cheiro caracteristico e o salicilato de metila.A Tese de Fabiana Cristina Missau, do Programa de Pos-Graduacao em Quimica da Universidade Federal de Santa Catarina (https://repositorio.ufsc.br/bitstream/handle/123456789/91853/251329.pdf?sequence=1) demonstra em ensaios in vitro, que a especie Polygala paniculata, rica em salicilato de metila, dentre outras acoes, apresenta atividade antinociceptiva, atividade anti-inflamatoria no modelo de edema de pata, induzido pela injecao intraplantar de carragenina nas cobaias, atividade gastroprotetora, acao antifungica, no modelo da concentracao inibitoria minima (CIM), frente a quase todos os fungos testados (Candida albicans, Candida krusei, Candida tropicalis, Candida parapsilosis, Candida glabrata, Sporothrix schenckii e Criptococcus neoformans).Foto: Polygala spAutoria: Gleiciane Gabrielli Outros textos do tema:http://quintaisimortais.blogspot.com.br/2017/01/flora-em-santo-antonio-do-pinhal-sp.htmlhttp://quintaisimortais.blogspot.com.br/2017/02/flora-em-santo-antonio-do-pinhal-sp.html Date: February 6, 2017 Source: Friedrich Schiller University Jena Summary: Roasted and salted, ground as a baking ingredient or fresh from the shell for all those who enjoy eating nuts, there is good news from nutritionists.

Roasted and salted, ground as a baking ingredient or fresh from the shell -- for all those who enjoy eating nuts, there is good news from nutritionists at Friedrich Schiller University Jena (Germany). Their latest research shows that nuts can inhibit the growth of cancer cells. "For a long time now we have known that nuts are full of substances that are good for the heart and the cardiovascular system, or that protect against becoming overweight or developing diabetes," says Dr Wiebke Schlormann. Some studies have also indicated a protective effect against colon cancer, she adds. "What we have not known in detail up to now is what this protective effect of nuts is based on." Dr Schlormann and her colleagues from the Department of Nutritional Toxicology at the University of Jena are now in a position to give specific answers to that question. In a publication in the specialist journal 'Molecular Carcinogenesis', they present results from a recent study, which throw light on the molecular mechanisms of this protective effect (DOI: 10.1002/mc.22606). According to this study, nuts have a positive effect on health because, among other things, they are involved in activating the body's own defences for detoxifying reactive oxygen species. Such substances, which are created by ultraviolet radiation, various chemicals or distinct food metabolites, for example, can cause DNA damage that leads to cancer development. "The body has a whole series of protective mechanisms that render reactive oxygen species harmless," explains Dr Schlormann. The nutritionists in Jena have now shown that these mechanisms are
