The CINC-1 is a member of rat interleukin-8 with chemotactic and activating properties to neutrophils. The CINC-1 induction in LPS-stimulated rat peritoneal macrophages was analyzed using a sensitive enzyme-linked immunosorbent assay. The peritoneal macrophages contained about 3 ng/ml as a basal level, and induced to maximal 18 ng/ml of CINC-1 by stimulation with 5 ${\mu}g/ml$ of LPS. Antiinflammatory steroids of dexamethasone and triamcinolon significantly suppressed the CINC-1 induction, where as aspirin and idomethacin did not show suppression. Inhibitory effects on the CINC-1 induction by natural triterpenoids having steroidal structures were analyzed. Among the 39 kinds of triterpenoids isolated from herbal medicines, acacigenin B and nigaichigoside F1 exhibited the highest suppression on the CINC-1 induction.

A rat chemokine, cytokine-induced neutrophil chemoattractant-1 (CINC-1) has chemotactic and activating properties to neutrophils. Rat kidney epithelioid NRK-52E cells contained 4 ng/ml of ClNC-1 as a basal level and their CINC-1 production was significantly increased by stimulation with lipopolysaccharide (LPS) of E. coli. Maximal induction of ClNC-1 was 58 ng/ml when 3 ${\mu}g/ml$ of LPS was treated to the NRK-52E cells. Inhibitory effects on CINC-1 induction in LPS-stimulated NRK-52E cells by extracts prepared from herbal medicines and wild plants in Korea were analyzed. At the final concentration of 100 ${\mu}g/ml$ , 9 species out of 304 species of herbal extracts exhibited more than 50% of inhibition on the CINC-1 induction. The active extracts prepared from Artemisia argyi, Lythrum salicaria, Machilus thunbergii, Magnolia sieboldii, Nelumbo nucifera, Prunus persica, Rubus coreanus, Sanguisorba officinalis, and Tripterygium regelii have been sequentially fractionated to obtain methylene chloride, ethyl acetate, butanol, and aqueous layers. Among solvent fractions of the active herbal extracts, methylene chloride fractions of Artemisia argyi and Magnolia sieboldii exhibited the highest inhibitory effects on CINC-1 induction in LPS-stimulated NRK-52E cells.

CINC-1 is a member of chemokine family with chemotactic and activating properties to neutrophils. CINC-1 induction in IL-$1{\beta}$-stimulated rat fibroblast NRK-49F cells was quantitated by a sensitive ELISA. CINC-1 production was increased up to 135 ng/ml from basal 2-6 ng/ml by stimulation with IL-$1{\beta}$.Steroidal anti-inflammatory drugs including dexamethasone and prednisolone exhibited potent suppressive effects on IL-$1{\beta}$-induced CINC-1 production. Among 39 kinds of natural triterpenoids tested, acacigenin B exhibited the highest suppressive effects with about $10{\mu}M$ to be 50% of inhibition on the CINC-1 induction. The suppressive potency of acacigenin B on IL-$1{\beta}$induced CINC-1 production was about 10-fold less than that of the steroidal anti-inflammatory drugs.

Objectives : This study aimed to evaluate the effects of Polygoni avicularis Herba Herbal-acupuncture( PaH-HA) at KI10(Umgok) on nephritis induced by lipopolysaccharide(LPS) in rats. Methods : Rats were allocated into normal, control, and 3 experimental groups. The rats in the control group were intra-peritoneally injected with LPS for nephritis induction. The rats in the groups of experiment 1, experiment 2, and experiment 3 were treated with single needle prick, saline injection, and PaH-HA, respectively at KI10 three times for a week and then injected with LPS. To evaluate the effects of PaH-HA at HI10, WBC count in blood, serum CINC-1, renal TNF-${\alpha}$ and renal MPO were measured. Results : Needle prick at KI10 suppressed the increase of WBC in blood and CINC-1 in serum of LPS-stimulated rats. Saline injection at KI10 suppressed the increase of WBC in blood. PaH-HA at KI10 suppressed the increase of WBC in blood, CINC-1 in serum, and MPO in kidney of LPS-stimulated rats. Conclusions : PaH-HA at KI10 has an anti-inflammatory effect on LPS-induced nephritis in rats and there may be a synergism between KI10(Umgok) stimulation and PaH-HA Solution.

Objectives: To investigate the anti-inflammatory effects of cultivated wild ginseng pharmacopuncture in lipopolysaccharide (LPS)-induced inflammatory rat model. Methods: Sprague-Dawley rats were divided into 4 groups; LPS control (n=6), LPS+cultivated wild ginseng pharmacopuncture at CV4 (n=6), LPS+cultivated wild ginseng pharmacopuncture at CV17 (n=6), and LPS+cultivated wild ginseng pharmacopuncture at Ex-HN1 (n=6). Pharmacopuncture (0.1 ml) was given every two days for 4 weeks followed by inflammation induction by peritoneal LPS injection (5 mg/kg). Blood, liver tissue, and peritoneal lavage fluid were taken and proinflammatory cytokines and other related factors were analysed. Results: Compared with the control group, CV4 and Ex-HN1 pharmacopuncture groups significantly attenuated plasma IL-$1{\beta}$, IL-6, and TNF-$\alpha$ increase at 2h and 5h after LPS injection (P<0.05). A significant difference from control group emerged at 5 h for plasma IL10 (P<0.05). For liver cytokines analyzed at 5 h after LPS injection, only CV4 pharmacopuncture group showed significant difference in TNF-$\alpha$ and IL-10 (P<0.05). Blood CD4/CD8 ratio and the phagocytic activities of polymorphonuclear neutrophils were not different from those of control group in all pharmacopuncture groups (P>0.05). CV4 pharmacopuncture significantly attenuated increase of plasma ${NO_3}^-/{NO_2}^-$, Intracellular adhesion molecule-1 (ICAM-1), cytokine-induced neutrophil chemoattractant-1 (CINC-1), and prostaglandin $E_2$ ($PGE_2$) compared with the control group (P<0.05). Monocyte chemoattractant protein-1, $PGE_2$, and CINC-1 level of CV4 pharmacopuncture group was significantly different from those from the control group (P<0.05). Conclusions: These results indicate that cultivated wild ginseng pharmacopuncture at CV4 may have a potent anti-inflammatory effect in an LPS-induced inflammatory rat model.

Objectives: The purpose of this study was to evaluate the effects of Polyporus Herbal-acupuncture(PO-HA) at KI10 (Umgok) on nephritis induced by lipopolysaccharide(LPS) in rats. Methods: Rats were allocated into normal, control, and 2 experimental groups. The rats in the control group were intra-peritoneally injected with LPS for nephritis induction. The rats in the groups of experiment 1 and experiment 2 were treated with Saline injection, and PO-HA, respectively at KI10 three times for a week and then intra-peritoneally injected with LPS. To evaluate the effects of PO-HA at KI10, WBC count in blood, creatine, tumor necrosis factor-alpha (TNF-${\alpha}$), cytokine-induced neutrophil chemoattractant 1(CINC-1) in serum, urinary volume, creatinine, total protein in urine, myeloperoxidase(MPO) in kidney were measured. Results: PO-HA at KI10 significantly suppressed the increase of WBC in blood, TNF-${\alpha}$, CINC-1 in serum, MPO in kidney of LPS-stimulated rats. PO-HA at KI10 significantly suppressed the increase creatinine, total protein in urine of LPS-stimulated rats. Conclusions: According to these results, it is postulated that PO-HA at KI10 has an anti-inflammatory and renal-protective effects on LPS-induced nephritis in rats. Therefore, it is suggested that PO-HA at KI10 may be an useful therapeutics for nephritis in clinical field after further researches.
