The effect of herbal medicine on osteoporosis was studied using ovariectomized rats as an animal model of Type I osteoporosis and SAM P6 mice as that of Type II. Each traditiona l boiling water extract of Achyranthis Radix, Psoraleae Radix, Rehmanniae Radix Preparat, Corni Fructus and Mycelia of Ganoderma, and systemic water fraction of Astragali Radix was given 5g(dried herbal weight)/kg/day p.o. for 30 days in each group of ovariectomized rats, SAM R1 and SAM P6. The extract of Cervi parvum Cornu was given for 14 days only. One ml of blood was taken by tail vein at day 0, 7, 14, 21 and 30 days after administration of the extract. Plasma levels of alkaline phosphatase, calcium, creatinine,inorganic phosphate, blood urea nitrogen, cortisol, total $T_3\;and\;total\;T_4$ were measured. In ovariectomized rats, administration of Achyranthis Radix or Corni Fructus decreased in alkaline phosphatase and that of Achyranthis Radix or Psoraleae Radix decreased in calcium comparing to the control (p<0.05). The administration of Psoralese Radix decreased in calcium and increased in urea comparing to day o(P<0.05)(Table I). There were not much changes in plasma calcium, inorganic phosphate, and alkaline phosphatase concentrations after uptake of these herbal medicine used in SAM P6(Table III). However, administration of Astragali Radix altered plasma inorganic phosphate and creatinine levels in SAM R1(p<0.01)(Table UU). The administration of Corni Fructus or Psoralease Radix induced the changes in plasma concentrations of cortisol, total $T_3$ and total $T_4$ in Type I(p<0.05) (Table IV). The uptake of Cervi parvum Cornu increased in total $T_3$ concentration and that of Mycelia of Ganodtragali Radix in SAM P6. However, the uptake of Mycelia of Ganoderma induced changes in cortisol and $T_4$ concentrations in SAM R1(p<0.05). Thus, there were significant differences in responses of herbal medicine in different types of osteoporosis.

Objectives: We investigated whether a mixture of the main component of pomegranate concentrated powder (PCP) with appropriate proportions of Eucommiae Cortex (EC) and Achyranthis Radix (AR) could act synergistically as an effective treatment for osteoarthritis (OA). Methods: In order to evaluate the effects of PCP, EC, and AR against OA, knee thicknesses, maximum extension angle of each knee, anti - inflammation effects, the transcript levels of chondrogenic genes mRNA expressions in femur and tibia articular cartilage (AC) with synovial membrane (SM) were analyzed. In addition, the histopathology and immunohistochemistry of the femur and tibia AC or SM were performed. Results: The surgically-induced OA signs in rats were significantly inhibited by 28 days of continuous treatment of PCP, EC and AR single formulas, and PCP with EC:AR mixed formulas. Especially, PCP with EC:AR 4:1, 2:1 and 1:1 mixed formula treatment constantly showed significantly more favorable inhibitory activities, as compared with those of single formula of PCP, EC and AR treated rats. Conclusion: PCP and EC:AR 4:1 mixed formula showed similar OA refinement effects through potent anti-inflammatory pathways as compared with those of diclofenac treatment, and showed additional chondrocyte proliferating effects on the both femur and tibia AC.

Objectives : Achyranthis Bidentatae Radix (ABR) has been used for treating of many symptoms especially osteoporosis and rheumatoid arthritis. In this study, we determined the effects of water extract of ABR in RANKL (Receptor Activator for Nuclear Factor $\kappa$ B Ligand)-induced osteoclast differentiation culture system. Methods : We assayed mRNA expression levels of NFATc1, c-Fos, TRAP, OSCAR, $FcR{\gamma}$, DAP12 and GAPDH in bone marrow macrophages (BMMs) treated with ABR. The protein expression levels of NFATc1, c-Fos, MAPKs and $\beta$-actin in cell lysates treated with ABR were analysed by Western blotting. In addition we determined the effects of water extract of ABR on LPS-induced bone-loss mouse. Results : Water extract of ABR showed remarkable inhibition on RANKL-treated osteoclast differentiation without cytotoxicity. ABR down-regulated the induction of c-Fos and NFATc1 by RANKL. ABR suppressed phosphorylation of JNK, p38 and I-${\kappa}B$. ABR rescued bone erosion by LPS induction in vivo study. Conclusions : These results demonstrate that ABR may be a useful remedy for curing of bone-loss disease such as osteoporosis.

Objective : As more and more people are interested in appearance in modern society, the increasing number of hair loss population can have an important impact on psychological and social problems such as depression and inappropriate interpersonal symptoms. Therefore, much research is being done on treatments for alopecia using herbal extracts with relatively few side effects. This study was investigated about the effect of Achyranthis Radix (AR) extract with ethanol solvent on hair growth. Methods : We determined the promoting efficacy of AR-ethanol extract compared with minoxidil (MNXD) on the growth of human hair dermal papilla cells (HDPCs). Cell viability was measured by MTT assay and cell proliferation was confirmed by cell cycle analysis from flow cytometry in HDPCs. Also, we monitored the safe concentration range through MTT assay. And protein expression of hair growth-related genes (insulin-like growth factor 1 (IGF-1), Wnt3a, Protein kinase B (Akt), Extracellular signal-regulated kinase (Erk)) was monitored by western blot. Results : On cell cycle analysis, the G2/M phase was higher than that of the DW group in AR ethanol extract group at 0.05 and 0.1 mg/㎖. All protein expression levels of HDPCs were increased in AR ethanol extract groups and the MNXD group, compared to the DW group, respectively. Conclusion : As mentioned above, AR extract increased cell proliferation and the protein expression of IGF-1, Wnt3a, Akt, Erk in HDPCs. These results suggest that AR ethanol extract has promoted hair growth and it might be potential hair growth supplement.
