Quadro hematologico e peso do baço de camundongos com tumor de Ehrlich na forma sólida tratados com Agaricus blazei

Este trabalho teve como objetivo avaliar a utilização do Agaricus blazei nas formas de filtrado e suspensão total aquosa (10mg/animal) na terapêutica de camundongos portadores de tumor de Ehrlich sólido, testando sua atividade anti-neoplásica. Os animais tratados diariamente com A. blazei apresentaram valores maiores dos parâmetros hematológicos (eritrograma e leucograma), e peso relativo final do baço quando comparados com o grupo controle (água destilada), porém sem diferença significativa (P>0,05)

Pervasive gaps in Amazonian ecological research

Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by 2050. This means that unless we take immediate action, we will not be able to establish their current status, much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio

Tratamento tópico de coelhos com Agaricus blazei Murril após envenenamento botrópico experimental

Este trabalho teve como objetivo avaliar a utilização do cogumelo Agaricus blazei Murril (5%) na terapêutica tópica do envenenamento experimental de coelhos por Bothrops alternatus, visando a antagonização dos efeitos locais (edema, hemorragia e necrose) provocados por esse veneno. Os resultados finais mostraram um menor grau de edema e do halo hemorrágico no grupo tratado quando comparados com o grupo controle (salina)

Extratos de Curcuma longa L. e Kalanchoe brasiliensis Camb. no tratamento local do envenenamento por Bothrops alternatus

Este trabalho teve como objetivo a utilização dos extratos aquosos das plantas Curcuma longa e Kalanchoe brasiliensis na terapêutica tópica complementar do envenenamento botrópico experimental em camundongos, visando a antagonização dos efeitos locais (edema, hemorragia e necrose) provocados pelo veneno. O experimento mostrou que os melhores resultados foram obtidos com o extrato de Kalanchoe brasiliensis
