“…[18][19][20][21] The finding that N. procerum LAE dose-dependently inhibits LPS-induced neutrophil accumulation in the mouse pleural cavity, reinforces our previous results 1) and clearly demonstrates the anti-inflammatory activity of this extract. The multistep process underlying the mechanisms involved in the development of endotoxin triggered tissue neutrophilia depends on at least three combined cellular components: (i) resident cells that primarily recognize the LPS; (ii) the chemoattractants/cytokines produced in situ (e.g., PAF, MIP-1a and KC); and (iii) the transmigrating and activated neutrophils themselves.…”

“…As shown in Fig. 1B, in vivo LPS stimulation also triggers PGE 2 production within 6 h. Consistent with N. procerum LAE ability to inhibit cyclooxygenase-2 (COX-2) in vitro, 1) here we demonstrate that in vivo LPS-induced pleural PGE 2 production was also sensitive to N. procerum LAE pre-treatment in a dose-dependent manner.…”

“…This method is simple and reliable, and affords rapid evaluation of peripheral analgesic action (Amendoeira et al, 2005). The extract and phases of C. racemosa tested in this study showed significant effect on this viscero-somatic model (tonic pain) reflected in a significant reduction of the acetic acidinduced abdominal writhing.…”

“…Alguns estudos farmacológicos foram realizados com extratos aquosos das folhas desta espécie e revelaram que apresenta importante potencial terapêutico, com destaque particular à atividade antialérgica, uma vez que apresenta potente atividade antieosinófila. 42 Estudos complementares mostraram que os extratos de N. procerum apresentam uma faixa de efeitos anti-inflamatórios distintos dos efeitos antialérgicos, incluindo potente atividade analgésica, 43 a qual não está associada com a ativação de receptores opioides, mas à inibição seletiva da produção de PGE 2 . Os mecanismos envolvendo os efeitos antiinflamatórios do extrato aquoso desta espécie também foram avaliados sequencialmente pelo mesmo grupo de pesquisa.…”

“…45 Outra espécie que tem apresentado potencial terapêutico é a Nidularium procerum, com destaque particular às atividades antialérgica, anti-inflamatória e potente atividade analgésica. [42][43][44] Do ponto de vista químico, as espécies mais estudadas foram o Ananas comosus e a Tillandsia usneoides, sendo o primeiro certamente por questão de sua importância econômica mundial e o segundo em função de seu uso popular e ampla distribuição no continente americano. Nos poucos estudos pode-se constatar que duas classes de substâncias são características na família: flavonoides, especialmente com padrão de oxigenação na posição 6, e cicloartanos.…”
