디지털 프린팅, 인쇄시장의 대안이 될 수 있나? - 인쇄시장에서의 디지털 프린팅 동향
한옥경 한국광학기기산업협회 2003 光學世界 Vol.86 No.-
`디지털`자체가 화두가 되어버린 지금 업계에 불어 닥치고 있는 개별 마케팅의 바람을 타고 디지털 프린팅에 대한 관심이 부쩍 높아졌다. 개별 마케팅이란 고객에 대한 개별적인 정보관리를 통하여 그 고객에게 가장 적합한 마케팅을 실현하는 기법으로서 이를 위해서는 브로슈어나 프로모션용 출력물 제작시 고객의 요구에 적합한 맞춤형 정보 및 서비스가 제공되어야 하며, 이 경우 소량 다품종 출력이 가능한 `1:1 디지털 프린팅`의 활용이 필수적이다. 따라서 대부분의

Angelica sinensis radix, Danggui, is a traditional oriental medication, which has been used to modulate immune respones. We report here that aqueous extract of Angelica sinensis radix (ASR) can induces No production, and inhibit LPS-induced No prodcution in dose-dependent manner in RAW 264.7 macrophage cells. ASR also induces iNOS mRNA and iNOS protein expression, and exhibit inhibitory effect on iNOS mRNA and protein expression in a dose-dependent manner in LPS-stimulated RAW 264.7 macrophage cells. Cytokines involved in the regulation of inflammatory reaction and immune response may play a role in the pathogenesis. ASR induces pro-inflammatory cyotokine gene expression (1L-q a, IL-1 B and IL-6 gene) in a dose-dependent manner, and inhibits the expressions of these cytokines in LPS-stimulated RAW 264.7 macrophage cells. These data indicate that(1) ASR may be a potential therapeutic modulator of NO synthesis in various pathological conditions, and (2) the immunomodulatory effects of ASR may be, in part, associated wiith the inducing or suppression of pro-inflammatory cytokine gene expressions.

The present study was conducted to evaluated the regulation mechanism of nitric oxide(NO) by water-extracted Cyperus rotundus (WCR) in RAW 264.7 macrophages. We investigated the effects of cell proliferation in mouse spleen cell and RAW 264.7 macrophages cells. WCR enhanced mitogenic activity in the dose-response manner in mouse spleen cells and RAW 264.7 macrophages cells. In nitric oxide (NO) synthesis by WCR, WCR alone had an effect on NO synthesis. It was found that the production of NO of RAW 264.7 cells stimulated with lipopolysaccharide (LPS) could be markedly inhibited by WCR. Inhibition of NO production was achieved by reducing inducible nitric oxide syntheses(iNOS) mRNA expression. The expression of IL-1 gene by WCR was investigated using reverse transcription polymerase chain reaction (RT-PCR). In RT-PCR, IL-1 family(IL-1 α, IL-1β) expressions were induced by WCR. These finding suggested that regulation of NO production by WCR may be, at least in part, associated with the regulation of iNOS mRNA expression and IL-1 family gene expression.
