“…Recently, a group described the indication of "açaí" juice as clinical oral contrast agent for magnetic resonance imaging signals of the gastrointestinal tract (Cordova-Fraga et al, 2004). Our group had demonstrated other effects of Euterpe oleracea such as antinociceptive and anti-inflammatory (Marinho et al, 2003;Matheus et al, 2003). As part of our continuous interest in Brazilian native plants and our intention of confirming the pharmacological use of "açaí" in the treatment of inflammatory processes in folk medicine, we studied its effects on NO production and cell viability.…”

“…As concentrações de 0,01, 10 e 100 μg/mL de uleína não favoreceram produção de NO em células RAEC, e em células B16F10 não houve produção signifi cativa nas concentrações de 0,01, 0,1, 10 e 100 μg/mL, quando comparadas ao controle contendo células não estimuladas (3,7 ± 0,2 μM   para RAEC e 2,4 ± 0,1 μM  para B16F10). Matheus et al (2003) demonstraram que células RAW 264.7 estimuladas com lipopolissacarídeo bacteriano (100 ng/mL) e interferon-alfa (10 U/mL) produziram uma grande quantidade de óxido nítrico (35 μM) quando comparadas com células não estimuladas (3 μM). Fushiya et al (1999) demonstraram a inibição da síntese de NO em macrófagos utilizando extrato metanólico obtido das partes aéreas de C. droserifolia e com substâncias isoladas de outras plantas tal como Lycium chinese (Kim et al, 1997) e Magnolia sieboldii (Park et al, 1996).…”
