인삼의 중성 Dammarane계 사포닌의 다형핵 백혈구 기능에 미치는 영향

Effects of Neutral Dammarane Saponin from Panax ginseng on the in vitro Function of Polymorphonuclear Leukocytes

인삼에서 분리한 항염성분이 일찍이 파낙스 사포닌(${\beta}-{\beta}'$(Rc는 아님)는 chemotaxis에 억제효과($27.6-42.1\%$)를 나타내었는데 이는 스테로이드계 항염증제인 DXM으로 관찰한 것과 같거나 또는 더 강력하였다.($29.6\%$). DXM이 PMNL 화학발광을 억제하는 반면에 중성 사포닌에서는 효과가 관찰되지않았다. 인삼뿌리에서 추출한 몇 종류의 중성 dammarane계 사포닌이 PMNL 기능을 조절하는 효과가 있었으며 그 효과는 항염증제인 dexamethasone 과는 작용면에서는 다른 것으로 사료된다.

Although Saponin A from Panax ginseng has previously been shown to inhibit carageenin induced edema. a paucity of information exists on the effects of components from ginseng on the cellular inflammatory response. specifically polymorphonuclear leukocyte (PMNL) function. The purpose of this study was 10 determine the effects of isolated neutral dammarane saponins from ginseng (i.e..glycosidic derivatives of 20(S)-protopanaxadiol [ginsenoside $Rb_1,\;Rb_2$ and Rc] and 20(S)-protopanaxatriol [ginsenosides Re and $Rg_1$]) on in vivo PMNL function and to compare their effects with those produced by a steroidal anti-inflammatory agent (dexamethasone) and commercially available saponin. Dexamethasone. the ginsenosides and saponin were all shown to he potent inhibitors of PMNL chemotaxis using the $^{51}Cr$ assay with $5{\times}10^{-8}M$ f-met-leu-phe [FMLP] as the chemoattractant. Inhibition or PMNL chemotaxis by dexamethasone. the ginsenosides and saponin were all shown to be both time-and dose-dependent and these agents did not affect cellular viability at the concentrations tested Saponin and the ginsenosides were more potent inhibitors of chemotaxis than was dexamethasone. while oxidant generation (as measured by the luminol-enhaneed chemil-uminescence of PMNL using FMNL $[10^{-6}]$ as the stimulus) was inhibited by dexamethasone. the ginsenosides $(Rb_1\;Rb_2\;Rc\;Re\;and\;Rg_1)$ and saponin at a concentration of 1 ${\mu}M$ had no significant effect on PMNL chemiluminescence. Thus. the neutral dammarane saponins are potentially important modulators or PMNL function and their inhibitory effects may he differentiated from those of the Steroidal anti-inflammatory agents.
