This study was designed to identify the effects of Polygoni cuspidati Radix(PCR) on the generation of superoxide anion radicals (${\cdot}O_2{^-}$), nitric oxide (NO), peroxynitrite ($ONOO^-$) in the renal epithelial cells of mouse(LLC-$PK_1$). The effects of PCR on the expression of inflammation-related proteins, IKK-${\alpha}$, phospho-$I{\kappa}B-{\alpha}$, NF-${\kappa}B$ (p50, p65), COX-2, iNOS, IL-$1{\beta}$, VCAM-1, were examined by western blotting. For this study, the fluorescent probes, namely dihydrorhodamine 123 (DHR 123), 2',7'-dichloro dihydrofluorescein diacetate (DCFDA), 4,5-diaminofluorescein (DAF-2) were used. Protein expression levels of IKK-${\alpha}$, phospho-$I{\kappa}B-{\alpha}$, NF-${\kappa}B$ (p50, p65), COX-2, iNOS, IL-$1{\beta}$, VCAM-1 were assayed by western blot. PCR reduced $H_2O_2$-induced cell death dose-dependently. It inhibited the generation of ${\cdot}O_2{^-}$, NO, $ONOO^-$ and $PGE^2$ in the $H_2O_2$-treated LLC-PK1 cells in vitro. PCR inhibited the espression of IKK-${\alpha}$, phospho-$I{\kappa}B-{\alpha}$, COX-2, iNOS, IL-$1{\beta}$ and VCAM-1 genes by means of decreasing the NF-${\kappa}B$ activation. These results suggest that PCR is an effective NO, ${\cdot}O_2{^-}$, $ONOO^-$ scavenger, and this substance recommended to be applied in treatment for the inflammatory process and inflammation-related disease.

Objectives: This study was conducted to evaluate the inhibitory effect of polygoni cuspidati radix (PCR) extract on osteoclast differentiation. Methods: MTT-assay was performed to estimate cytotoxicity of PCR extract in BMMs stimulated with RANKL. Tartrate resistant acid phosphatase (TRAP) staining, TRAP activity and RT-PCR were performed to know the inhibitory effect on osteoclast differentiation. actin ring formation were analysed to observe the effect of PCR extract. Results: PCR decreased the number of TRAP positive cells and TRAP activities in BMMs stimulated with RANKL and M-CSF. PCR restrained the formation of actin ring. PCR down regulated the induction of NFATc1, c-Fos, TRAP and OSCAR by RANKL. PCR inhibited NF-${\kappa}B$ activity by inducing degradation of $I{\kappa}B{\alpha}$. Conclusions: We suggest that PCR Extracts can be an effective therapeutic agent on osteoclast differentiation caused by diseases such as osteoporosis.

Emodin, a naturally occurring anthraquinone derivative isolated from Polygoni cuspidati radix, has several beneficial pharmacologic effects, which include anti-cancer, anti-diabetic, and anti-inflammatory activities. In this study, the authors examined the effect of emodin on the production of proinflammatory cytokines, such as, tumor necrosis factor (TNF)-${\alpha}$ and interleukin (IL)-6, in mouse bone marrow-derived mast cells (BMMCs) stimulated with phorbol 12-myristate 13-acetate (PMA) plus the calcium ionophore A23187. To investigate the mechanism responsible for the regulation of pro-inflammatory cytokine production by emodin, the authors assessed its effects on the activations of transcriptional factor nuclear factor-${\kappa}B$ (NF-${\kappa}B$) and mitogen-activated protein kinases (MAPKs). Emodin attenuated the nuclear translocation of (NF)-${\kappa}B$ p65 and its DNA-binding activity by reducing the phosphorylation and degradation of $I{\kappa}B{\alpha}$ and the phosphorylation of $I{\kappa}B$ kinase B (IKK). Furthermore, emodin dose-dependently attenuated the phosphorylations of MAPKs, such as, extracellular signal-regulated kinase 1/2 (ERK1/2), p38 MAP kinase, and the stress-activated protein kinases (SAPK)/c-Jun-N-terminal kinase (JNK). Taken together, the findings of this study suggest that the anti-inflammatory effects of emodin on PMA plus A23187-stimulated BMMCs are mediated via the inhibition of NF-${\kappa}B$ activation and of the MAPK pathway.
