목적 : 콜라겐으로 관절염을 유발한 생쥐에서 RANKL발현에 대한 구척의 효과를 연구하였다. 방법 : 면역조직화학법을 이용하여 관절의 염증과 골의 손실 정도를 증명하였다. 콜라겐으로 관절염을 유발한 DBA/IJ종의 생쥐에 관절염 유발 3주후부터 8주까지 구척 (300mg/kg)을 투여한 후 발의 부종과 골 손실의 변화를 Safranin O염색으로 관찰하였다. 결과 : 5주간 구척의 투여로 관절의 부종과 무릎 관절의 염증을 막았다. 파골세포 분화인자인 RANKL은 대조군에 비해 구척 투여군의 관절에서 RANKL이 감소되었다. 결과 : 구척 투여의 결과로 골손실을 보호하였고, 뼈를 만드는 동화작용에 의해 RANKL의 발현을 개선할 수 있었다.

This study was done to investigate the antidiabetic and antioxidant effects of Cibotium barometz in Streptozotocin (STZ)-induced diabetic rats. Diabetes was induced by intravenous injection of STZ at a dose 45mg/kg.b.w. dissolved in citrate buffer(pH4.5). The ethanol extract of Cibotium barometz was orally administrated once a day for 7 days. The contents of serum glucose, triglyceride(TG) and total cholesterol were significantly decreased(p<0.05) in Cibotium barometz treated group compared to the those of STZ-control group, The content of glutathione(GSH) and activity of gluthathione-s-transferase(GST) were significantly increased (P<0.05) in Cibotium barometz treated group compared to the those of STZ-control group. and activityes of catalase(CAT) and glutathione peroxidae(GSH-Px) were signiicantly decreased (P<0.05) in Cibotium barometz treated group compared to the those of STZ-control group. Also the content of hepatic glycogen and activities of glucose-phosphate dehydrogenase(G-6-PDH)and glucokinase(GK) were significamtly increased(p<0.05), but activity of glucose-6-phosphatase (G-6-Pase) was significamtly decreased (p<0.05) in Cibotium barometz treated group compared to the those of STZ-control group. These results indicated that ethanol extract of Cibotium barometz would have antidiabetic and antioxidant effects in STZ-induced diabetic rats.

The effect of MeOH extract of Cibotium barometz (or Cibaro) on nogo-A expression was studied by neurite cone collapse and neurite outgrowth assay. The degrees of mRNA expression of BDNF, GDNF, and Caspase-3 in nogo-A were also examined with SK-N-SH cell lines using RT-PCR and confocal microscopy methods. We have shown that Cibaro treatment inhibits nogo-A activation in SK-N-SH cell lines. It has been shown that Cibaro increases the expression rates of neurofilament and enhances neurite outgrowth in neuroblastoma cells as increasing the amount of Cibaro. It has been also shown that Cibaro increases the expression rates of BDNF, GDNF mRNA in neuroblastoma cells as increasing the amount of Cibaro. These results suggest that Cibaro induces neutrite outgrowth by nogo-A inactivation and is, therefore, crucial for the treatments against anaplastic disc and spinal neuronal anesthesia.

The rhizome of Cibotium barometz has been used for variety of bone disease as a traditional medicine. In the present study, we examined the antioxidant and anti-inflammatory activities of 85% methanol extract of C. barometz. C. barometz exhibited potent scavenging effect on 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical, superoxide radical and nitric oxide radical. In IFN-$\gamma$/LPS-stimulated mouse peritoneal macrophage model, C. barometz suppressed nitric oxide production and IL-6 secretion dose-dependently. Moreover, C. barometz showed decreased iNOS and COX-2 expression without notable cytotoxicity. These results suggest that C. barometz may be an useful agent as an antioxidant and anti-inflammatory agent.

GCSB-5 preparation is a purified extract from a mixture of 6 medicinal plants(Acanthopanacis Cortex, Achyranthis Radix, Saposhnikoviae Radix, Cibotii Rhizoma, Glycine Semen Nigra, Eucommiae Cortex) that have been widely used for the treatment of various bone disorders. The aim of this study was to investigate HPLC analysis method and screening of standard compound on Cibotii Rhizoma for quality standardization of a medicinal crude drug GCSB-5. Onitin-4-O-$\beta$-D-glucopyranoside was isolated from Cibotii Rhizoma as the standard compound and identified on the basis of spectroscopic data such as NMR. HPLC analysis method for the determination of onitin-4-O-$\beta$-D-glucopyranoside was established for the quality control of the medicinal plants of Cibotii Rhizoma species, GCSB-5 raw material and GCSB-5 preparation. And validation of HPLC analysis methods were conformed for verification of HPLC methods by check to specificity, linearity, intra-day precision, inter-day precision and accuracy following ICH guideline.

Cibotii Rhizoma, the dried rhizome of Cibotium barometz J. Smith (C. barometz), has long been used to treat bone or nervous system disorders. In this regard, we isolated three main phenolic compounds, onitin-4-O-${\beta}$-D-glucopyranoside (1), irisdichototins E & F epimeric mixture (2), and protocatechuic acid (3) from C. barometz methanol extract. In addition, we screened their antioxidative activities by DPPH, ABTS radical, and superoxide scavenging assays. Among these three compounds, irisdichototins E & F and protocatechuic acid showed strong antioxidant activities. Also, the antioxidant activities of the C. barometz extracts were proportional to the contents of irisdichototins E & F and protocatechuic acid, thus these two phenolic compounds could be main active compounds of C. barometz. In addition, onitin-4-O-${\beta}$-D-glucopyranoside is considered as a marker compound of C. barometz because this compound is specifically contained in C. barometz which belongs to Pteridophyta order. A rapid analysis method for the simultaneous determination of phenolic compounds was also developed by UPLC (Ultra Performance Liquid Chromatography). Using the developed method, the two active compounds (irisdichototins E & F and protocatechuic acid) and a marker compound (onitin-4-O-${\beta}$-D-glucopyranoside) were successfully quantified in 14 commercial samples that were collected from different regions.

This study was purpose to investigate that Gucheokbogol-tang(GBT), mainly used in osteoporosis, has possible regulatory effect on bone regeneration by operating in proliferation and calcification of osteoblast. So that, their cytotoxicity and proliferation was investigated with MTT by ELISA, and morphological change was observed by optical microscope and electron microscope. And activation of alkaline phosphates(ALP) which is secreted in early stage of bone formation was measured, and accumulation of $Ca^{2+}$ in the process of calcification was investigated by alizaline red S assay(ARS). The results were as follows: The MG-63 cell, originated from human cell was activated in $10^{-5}$ treated group, and the level of ALP was also increased in the treated group, highest on the third day. And from the outcome of ARS assay of calcification process in the Gucheokbogol-tang(GBT) treated group for 21days. These results suggested that Gucheokbogol-tang(GBT) is effective in proliferation and calcification of osteoblast.
