  • Purpose: The aim of this study was to compare retrospectively the efficacy of anti-osteoporotic agents (RAL-Raloxifene 60 mg, ALD-weekly alendronate 70 mg, RSD-weekly risedronate 35 mg, AVD3-weekly alendronate 70 mg/vitamin $D_3$ 2800IU, IBD-quarterly IV ibandronate 3 mg/3 ml, ZLD-yearly IV zoledronate 5 mg/100 ml) in postmenopausal patients with osteoporosis or osteopenia. Method: This study retrospectively reviewed medical record and compared the lumbar spine BMD percentage changes of each medicine group one year later from the baseline. 209 patients (27, 50, 60, 30, 35, and 7 patients in RAL, ALD, RSD, AVD3, IBD, and ZLD groups, respectively) are within the inclusion criteria for the study. Results: From baseline to month 12, lumbar spine BMD increased significantly larger with bisphosphonate groups, compared to SERM (p < 0.05). In all bisphosphonate groups, the lumbar spine BMD were increased significantly from baseline. Of the bisphosphonates, the changes from baseline in BMD of IV bisphosphonates were more larger than those of oral bisphosphonates, and yearly, quarterly bisphosphonates yielded significantly greater BMD gains, compared with weekly bisphosphonate groups (p<0.05). In addition, patients receiving 70 mg weekly alendronate+vitamin D3 had greater gains in BMD than alendronate Single preparation (p<0.05). Conclusion: Bisphosphonates yielded significantly greater BMD gains than SERM. Of the bisphosphonates, the changes from baseline in BMD of yearly, quarterly IV bisphosphonates yielded significantly greater BMD gains, compared with weekly oral bisphosphonate groups. In addition, vitamin D3 plays an significant role in BMD gains.

  • In order to establish basic data of SAMP6 as an animal model for osteoporosis, present study has been designed to concentrate on the various biological aspects of SAMP6 such as growth index, hematology, blood biochemistry, biochemical characteristics, and bone and cortical thickness. Investigation period was for 15 months (3 months to 18 months of age) and biological characteristics have been examined throughout the study period. The results were summarized as follows : Decreased body weight of male SAMP6 was noticed from 7 months of age compared to from 18 months of age in female. Although there were no significant differences in organ weights, generally those of male mice were greater than those of females, especially in liver, kidney and lung. According to the analysis of blood biochemistry and hematology, the number of leukocytes in male mice was greater than that of female mice. There was a decrease in bone thickness in both male and female mice starting around from 7 months of age. Peak cortical thickness index was noticed at 5 months of age in both sexes. In femur, the highest $Ca^{2+}$ content for both sexes was noticed at 5 months of age, whereas the highest P$^{3+}$ content was noted at the age of 5 and 7 months in male and female mice, respectively. The contents of both elements were gradually decreased with age after peaks for both sexes. In summary, SAMP6 mice in KRICT colony show osteoporotic characteristics starting from 5 to 7 months of age, suggesting that at least 5 months of old animals should be used for studying the mechanism of osteoporosis or screening anti-osteoporosis drugs. This study also suggests that the cortical index thickness, $Ca^{2+}$ and P$^{3+}$ contents, and alkaline phosphatase activities can be used as indexes for drug screening.

  • Osteoporosis is characterized by the reduced density of mineralized bone matrix. The loss of bone has been attributed to an imbalance between bone formation and bone resorption. The silkmoth is one of the famous traditional tonic medicines. Silkworm pupa was evaluated for its antiosteoporotic activity in an ovariectomized rat model of osteoporosis. The rats were ovariectomized at 6weeks of age and divided into 7 groups. All the groups were fed without calcium diet. The OVX rats were treated with water and silkworm powder for 6 weeks. In OVX rats, the body weight, feeding and water intake quantity did not show a significant change, but the silkworm pupa powder immediately before the eclosion of Yeonrokjam was significantly increased the bone mineral density in the femoral bone. The silkworm pupa powder increased the bone with increasing calcium in serum. These results also showed its protective action through promotion of bone formation. The silkworm pupa powder has a definite antiosteoporotic effect; similar to estrogen, it is especially effective for the prevention of bone fracture induced by estrogen deficiency. The silkworm pupa powder is a promising anti-osteoporotic agent that can prevent bone fractures in osteoporotic patients. The silkworm pupa powder does not show serious side effects because natural herbal medicine origin.

  • Cervi parvum cornu (Deer Antler) and Carthami tinctorii fructus (Also known as Carthami seed) are widely used for treating osteoporosis and rheumatoid arthritis. In this study, We found out that the water extract of Cervi parvum cornu(WECPC), Carthami tinctorii fructus(WECTF) and their combination have effects of suppressing the RANKL-induced osteoclast differentiation. We assayed mRNA expression levels of NFATc1, c-Fos, TRAP and GAPDHS from bone marrow macrophages(BMMs) by means of RT-PCR. Similarly, the protein expression levels of NFATc1, c-Fos, MAPKs and $\beta$-actin in cell lysates were analyzed by means of Western blotting. then we determined the anti-osteoporotic effects of WECPC, WECTF and their combination using Lipopolysaccharide (LPS)-induced bone-loss mouse. WECPC, WECTF and their combination showed remarkable inhibition on RANKL-treated osteoclast differentiation without cytotoxicity. WECPC suppressed degradation of I-${\kappa}B$. WECPC, WECTF and their combination down-regulated the induction of c-Fos and NFATc1 by RANKL. Lastly, in vivo data showed that WECPC, WECTF and their combination rescued the bone erosion by LPS treatment. Thus, these results demonstrate that WECPC, WECTF and their combination can be efficacious remedies for bone-loss diseases such as osteoporosis and rheumatoid arthritis.

  • Background: In South Korea, 22.3% of women ${\geq}50years$ of age and 37% of women ${\geq}70years$ of age visit the doctor to obtain treatment for osteoporosis. According to the analysis of the National Health Insurance Services claim data between 2008 and 2012, the number and incidence of hip and vertebral fractures increased during the same period. Denosumab, a newly marketed medicine in Korea, is the first RANK inhibitor. Methods: A cost-utility analysis was conducted from a societal perspective to prove the superiority of denosumab to alendronate. A Markov cohort model was used to investigate the cost-effectiveness of denosumab. A 6-month cycle length was used in the model, and all patients were individually followed up through the model, from their age at treatment initiation to their time of death or until 100 years of age. The model consisted of eight health states: well; hip fracture; vertebral fracture; wrist fracture; other osteoporotic fracture; post-hip fracture; post-vertebral fracture; and dead. All patients began in the well-health state. In this model, 5% discounted rate, two-year maximum offset time, and persistence were adopted. Results: The total lifetime costs for alendronate and denosumab were USD 5,587 and USD 6,534, respectively. The incremental cost-effectiveness ratio (ICER) for denosumab versus alendronate was USD 20,600/QALY. Given the ICER threshold in Korea, the results indicated that denosumab was remarkably superior to alendronate. Conclusion: Denosumab is a cost-effective alternative to the oral anti-osteoporotic treatment, alendronate, in South Korea.

  • [Purpose] Sex hormones deficiency leads to dramatically bone loss in particular postmenopausal women. Royal jelly has anti-osteoporosis effect due to maintain bone volume in that condition. We hypothesized that royal jelly protein (RJP, a latent residue after extracting royal jelly) also prevents bone deficient in ovariectomized (OVX) female rats, the animal model of postmenopausal women. [Methods] Female Sprague-Dawley rats (n = 30, 6 weeks age old) were sham operated (Sham; sham operated group, n = 7), OVX control group (OC, n = 7), OVX with low RJP intake group (ORL, n = 8), and OVX with high RJP intake group (ORH, n = 8) during 8 weeks experimental periods. In the end point of this experiment, the bone samples (lumbar spine, tibia, and femur) were surgically removed under anesthesia. These bone samples were evaluated bone mineral density (BMD) and bone strength. [Results] BMD of lumbar spine in RJP intake groups (ORL, ORH) were higher than that in OC group (p < 0.05 and p < 0.01) in RJP intake volume dependent manner. BMD of tibial proximal metaphysis and diaphysis in RJP intake groups were also higher than these in OC group (p < 0.01 and p < 0.01 / p < 0.05 and p < 0.001). In addition, breaking force of femur in RJP intake groups were significantly increase compared with that in OC group (p < 0.001 respectively). [Conclusion] These findings indicate that RJP contribute to prevent sex hormone related bone abnormality.

  • Osteoporosis is an important public health issue in postmenopausal women. It is a major public health concern and is widely believed that osteoporosis results from imbalance between bone resorption and bone formation. Recently natural products from plants have been extensively studied as therapeutic drugs to treat and prevent various diseases. Hoelen (scientific name, Poria cocos) is a mushroom that is used in traditional Chinese medicine. Hoelen exhibits anti-inflammatory activity and has a protective effect on tumor progression. However, the effect of hoelen in osteoclast differentiation remains unknown. Thus, we examined the effect of hoelen in receptor activator of nuclear factor-${\kappa}B$ ligand (RANKL)-induced osteoclast differentiation. Hoelen significantly inhibited RANKL-induced osteoclast differentiation in bone marrow-derived macrophages (BMMs) in dose dependent manner without toxicity. Also, we showed that hoelen significantly inhibited the mRNA expression of tartrate-resistant acid phophatase (TRAP) and nuclear factor of activated T cells 1 (NFATc1) in BMMs treated with RANKL. In Particular, hoelen greatly inhibited the protein expression of NFATc1. Ectopic expression of NFATc1 partially reverses hoelen-mediated inhibition of osteoclast differentiation. Taken together, our results demonstrated that hoelen may be useful treatment option of bone-related disease such as osteoporosis, reumatoid arthritis, and periodontitis.

  • Purpose : The first purpose of this study is to find out whether the water extract of Rehmanniae Radix Preparat(RRP), Cuscutae Semen(CS) and their combination(Ssangbohwan, SBH) have the effect of suppressing Receptor activator of nuclear factor kappa-B ligand(RANKL)-induced osteoclast differentiation. The second purpose of this study is to find out whether the water extract of RRP, CS and SBH have the effect of inhibiting osteoporosis in an osteoporosis model induced by lipopolysaccharide(LPS). Methods : After promoting differentiation of osteoclasts by treating the RANKL, we observed the effect by the administration of RRP, CS and SBH. In addition, by means of Reverse transcription polymerase chain reaction(RT-PCR), we assayed mRNA expression levels of NFATc1, c-Fos, TRAP and GAPDHS(Glyceraldehyde-3-phosphate dehydrogenase, spermatogeni) from bone marrow macrophages(BMMs). Similarly, the protein expression levels of NFATc1 (Nuclear factor of activated T-cells, cytoplasmic1), C-Fos, MAPKs(Mitogen-activated protein kinases) and ${\beta}$-actin in cell lysates were analyzed by means of Western Blotting. Finally, we determined the anti-osteoporotic effects of RRP, CS and SBH, through the use of Lipopolysaccharide-induced bone-loss mouse. Results : RRP, CS and SBH showed remarkable inhibitive effect on RANKL-treated osteoclast differentiation without cytotoxicity. SBH inhibited the phosphorylation of p38, Jun N-terminal kinases(JNK), and I-${\kappa}B$ and down-regulated the induction of c-Fos and NFATc1 by RANKL. RRP, CS suppressed degradation of I-${\kappa}B$, but it did not affect c-Fos and NFATc1 by RANKL. Lastly, in vivo data showed that RRP and SBH prevented bone erosion by LPS treatment. Conclusions : These results demonstrate SBH can be effective remedy for bone-loss diseases such as osteoporosis.
