The present study was performed to investigate whether Achyranthes Radix extracts play roles in the bone metabolism. Three kinds of Achyranthes Radix extracts (methylene chloride (MC), ethylacetate (Ea), and water (W)) were used for bioassay. We examined cellular activities of osteoblasts by measurement of cell proliferation rate, alkaline phosphatase (ALP) activity, and calcified nodule formation. Osteoclast generation was assayed by measuring the number of tartrate-resistant acid phosphatase (TRAP) (+) multinucleated cells after culture of osteoclast precursor cells. There was a maximum 20% increase in proliferation rate of osteoblastic cells after treatment with MC. First and second subfraction of MC layer increased proliferation of osteoblast. Ea layer and second subfraction of MC layer increased ALP activity. Also MC layer and second subfraction of MC layer from Achyranthes Radix extracts increased the calcified nodule. MC layer and second subfraction of MC layer from Achyranthes Radix extracts significantly decreased in the number of TRAP (+) multinucleated cells. Taken together, Achyranthes Radix stimulates the proliferation and bioactivities of bone-forming osteoblasts, and inhibits activities of bone-resorbing osteoclasts.

The aim of this study was to assure the possiblility of Achyranthes japonica Nakai for a cosmetic material. For this we examined the Anti-oxidation, Anti-inflammation, Anti-wrinkle effects of Achyranthes japonica Nakai extract. Each material is extracted from Achyranthes japonica Nakai roots(AJNR) and Achyranthes japonica Nakai stalks(AJNS) using 70% ethanol. We carried out Nitric oxide assay of the extract with cultured RAW 264.7 macrophage cells, And we conducted MMP-1 assay, Type I procollagen synthesis assay of the extract with cultured CCD-986sk fibroblast cells. After we measured ABTS+ assay and SOD assay of AJNR and AJNS, we knew that effect of anti-oxidant increased as their concentration get higher. The result of this study was that the antioxidant activity of AJNR and AJNS was similarly excellent and the anti-inflammatory activity of AJNR was significantly higher than AJNS. The MMP-1 inhibitory activity and Type I procollagen synthesis of AJNR and AJNS was generally excellent, AJNS had slightly better than AJNR. Therefore I thought it has the chance to play an imfortant role as a functional cosmetic material for anti-oxidant, anti-inflammation and wrinkle reduction effects.

Objectives : Achyranthes bidentata radix (Usul) has been used as anti-arthritic, antiallergic, antidiuretic, and so on. Recently extracts of Achyranthes bidentata radix have shown anti-inflammatory and cancer preventive effects in vitro and in vivo. Methods : We therefore evaluated the inhibitory potential of ethanol extracts of Achyranthes bidentata radix on cytochrome P450 (CYP) isoforms-catalyzed reactions, which relate to causes of cancer and inflammation, including CYP1A2, CYP2C9, CYP2C19, CYP2E1, CYP2D6, CYP2C8, and CYP3A4, using human liver microsomal preparations. Results : The extracts showed weak or negligible inhibitory effects on CYP2C9-catalyzed (S)-warfarin 7-hydroxylation, CYP2C19-catalyzed S-mephenytoin 4-hydroxylation, and CYP2D6-catalyzed dextromethorphan O-demethylation with each IC50 over 1750 g/ml, respectively. However, it showed relatively significant inhibitory effect on CYP1A2-catalyzed phenacetin O-deethylation and CYP2E1-catalyzed chlorzoxazone 6-hydroxylation with IC50s of 970.5 g/ml and 821.4 g/ml, respectively. Conclusions : These results suggest that extracts of Achyranthes bidentata radix have inhibitory effects on CYP-catalyzed reactions, especiallyCYP1A2 and CYP2E1, in human liver microsomes. These effects appear to relate to anti-inflammatory and cancer prevention following decrease of reactive oxygen species formed by CYP, especially CYP1A2 and CYP2E1, by Achyranthes bidentata radix. However, further evaluation is necessary to demonstrate and to confirm its effects in human.

Physicochemical properties of Achyranthes japonica and Smilax china extracts were investigated for the purpose of functionality research on the natural bio-resources. Extraction contents were order of distilled water>methanol>ethanol solvent, the highest free aminoacids were proline from Achyranthes japonica, phosphoserine and glutamic acid from Smilax china, respectively. BI and TAC by spectrophotometric absorbance were order of methanol>ethanol>water in Smilax china leaf extract, but water>methaol>ethanol in Achyranthes japonica leaf extract. EDA was high in ethanol extract from Smilax china leaf and in methanol extract from Smilax china root, and in water extract from Achyranthes japonica. TBA value of Achyranthes japonica leaf and Smilax china leaf-ethanol extracts on olive oil was 82.1% and 84.0%, respectively, for that of an artificial antioxidant BHT. Antimicrobial effect was observed in Achyranthes japonica stem-methanol extract on Bacillus subtillis, in Smilax china leaf-ethanol extract on Bacillus subtillis, Vibrio vulnificus and Salmonella enterica, respectively. And the adsorption of Pb(II) on Achyranthes japonica was higher than that of Cd(II) on Smilax china under the same metal ion concentration.

Purpose: This study examined the effects of swimming exercise and Achyranthes Radix extracts on the inflammatory and behavioral responses in type II collagen-induced arthritic rats for 28 days. Methods: Sprague-Dawley rats were allocated randomly to one of the following four groups: only type II collageninduced (group Ⅰ), application of swimming exercise after type II collagen-induced (group II), application of Achyranthes Radix ointment after type II collagen-induced (group III), application of swimming exercise and Achyranthes Radix ointment after type II collagen-induced (group IV). Arthritis was established in SD rats by an intradermal injection of Chick type II collagen plus incomplete Freund's adjuvant at the base of the tail of the animals. The swimming exercise program consisted of a 25 min swimming session/day with a load corresponding to 5.5% of the weight bearing, three days/week for four weeks. The Achyranthes Radix ointment (0.1g) was applied twice a day for five days. The changes in behavior, H & E stain, and cyclooxygenase-2 (COX-2) level in the knee joint were assessed. Results: The gross and histological examination, after RA induction showed reddening, edema and erythema. The H & E stain revealed the destruction of articular cartilage, bony erosion and the infiltration of inflammatory cells after RA induction. The mechanical allodynia test results were significantly higher in group I than in groups II, III and IV (p<0.01). The immunohistochemistrical response of COX-2 in the knee joint showed that groups II, III, IV had a lower response effect than group I. Conclusion: Swimming exercise training and Achyranthes Radix ointment decreased the inflammatory responses and enhanced the behavioral responses in the arthritic rats.
