  • Osteoporosis is the leading underlying cause of fractures, particularly in postmenopausal women, due to the loss of estrogen-mediated suppression of bone resorption. More than 50% of adults 50 years of age or older are estimated to have osteoporosis. Osteoclast which is main target for treatment of osteoporosis is originated from hematopoietic cell line. Aloe has been widely used in worldwide country as a coadjuvant medicine. Extracts of the leaves of Aloe have been used in condition to improve dermatologic problem such as seborrheic dermatitis, aphthous stomatitis, xerosis, lichen planus and has been known to exert anti-inflammatory, anti-oxidant and anti-tumor effects. However, despite the popularity of aloe as a plant food supplements, the evaluation of its efficacy as a possible therapeutic option for osteoporosis remains scarce. Thus, we evaluated the effect of Aloe on receptor activator of nuclear factor-${\kappa}B$ ligand (RANKL)-induced osteoclast differentiation. Here we found that Aloe significantly inhibited osteoclast differentiation induced by RANKL. Aloe suppressed the activation of p38 pathway and $NF{\kappa}B$ in bone marrow macrophages (BMMs) treated with RANKL. Also, Aloe significantly inhibited the mRNA expression of c-Fos, tartrate-resistant acid phosphatase (TRAP), osteoclast-associated receptor (OSCAR), nuclear factor of activated T cells (NFAT)c1 and cathepsin K in BMMs treated with RANKL. Particularly, Aloe greatly inhibited the protein expression of c-fos and NFATc1. Taken together, our results suggested that Aloe may be useful tool for treatment of osteoporosis by inhibition of osteoclast differentiation.

  • Osteoporotic fracture became a serious social problem, which related with mortality and morbidity in old age population. Osteoclast which is responsible for bone resorption is originated from hematopoietic cell line and plays a key role osteoporotic bone loss. Cynanchum wilfordii (Asclepiadaceae) roots have been used in Korean folk medicine for the treatment of diabetes mellitus and aging progression. Also, recent studies have shown that the extract and fractions of Cynanchi Wilfordii Radix have various pharmacological actions including scavenging free radicals, enhancing immunity, reducing high serum cholesterol, and anti-tumor activity. However, the effect of extract of Cynanchi Wilfordii Radix in osteoclast differentiation had not been reported. Thus, we evaluated the effect of Cynanchi Wilfordii Radix on receptor activator of nuclear factor-${\kappa}B$ ligand (RANKL)-induced osteoclast differentiation. Through our study, we found that Cynanchi Wilfordii Radix significantly inhibited osteoclast differentiation induced by RANKL. Cynanchi Wilfordii Radix suppressed the activation of p38 pathway and $NF{\kappa}B$ in bone marrow macrophages (BMMs) treated with RANKL. Also, Cynanchi Wilfordii Radix significantly inhibited the mRNA expression of c-Fos, tartrate-resistant acid phosphatase (TRAP), osteoclast-associated receptor (OSCAR), nuclear factor of activated T cells (NFAT)c1 and cathepsin K in BMMs treated with RANKL. Particularly, Cynanchi Wilfordii Radix inhibited the protein expression of c-fos and NFATc1. Taken together, our results demonstrated that Cynanchi Wilfordii Radix may be useful treatment option of bone-related disease such as osteoporosis leads to fracture of bone and rheumatoid arthritis.

  • 본 연구에서는 아직 까지 연구되지 않은 말굽버섯의 면역증강 효과를 설치류 대식세포에서 검증하였다. 연구결과에 따르면 말굽버섯 메탄올 추출물(FFE)의 처리에 의해 대식세포의 산화질소의 생성이 농도 의존적으로 증가되었다. 산화질소의 생성이 증가된 이유는 산호질소의 생성을 유도하는 효소인 iNOS의 발현이 FFE에 의해 증가되었기 때문이었다. FFE는 면역반응에 중요한 cytokine인 TNF-${\alpha}$, IL-$1{\beta}$, IL-6의 생성도 농도 의존적으로 증가 시켰다. 이 같은 FFE의 면역증강 활성은 면역활성을 중계하는 세포 신호전달분자 중 NF-${\kappa}B$와 MAP Kinases의 활성증가에 의한 것임을 확인 할 수 있었다. 본 연구 결과는 말굽버섯의 임상적 적용에 중요한 자료로 활용될 것이며, 만일 말굽버섯으로부터 분리한 단일성분에서 면역증강활성을 검증 하게 된다면 새로운 식 의약소재로서의 가치를 인정 받을 수 있을 것으로 생각된다.

  • Chijabaegpi-tang (CHG) is an oriental herbal medicine that has been used for its various pharmacological effects, which include anti-inflammatory, anti-oxidant and immunoregulation activities. In the present study, we investigated which skin inflammations are involved in the $TNF-{\alpha}/IFN{\gamma}$-induced HaCaT cells. We investigated the suppressive effect of CHG on $TNF-{\alpha}/IFN{\gamma}$-induced HaCaT cell production of the following chemokines: macrophage-derived chemokine (MDC)/CCL22; regulated on activation, normal T-cell expressed and secreted (RANTES)/CCL5; and interleukin-8 (IL-8); thymus and activation-regulated chemokine (TARC)/CCL17. The pre-treatment of HaCaT cells with CHG suppressed $TNF-{\alpha}/IFN{\gamma}$-induced nuclear transcription factor kappa-B ($NF-{\kappa}B$). In addition, CHG inhibited $TNF-{\alpha}/IFN{\gamma}$-induced phosphorylation of ERK and p38. $TNF-{\alpha}/IFN{\gamma}$ suppressed the expression of skin barrier proteins, including filaggrin (FLG), Involucrin (IVL) and loricrin (LOR). By contrast, CHG restored the expression of FLG, IVL and LOR. Taken together, our findings suggest that CHG could be a therapeutic agent for prevention of skin disease, including atopic dermatitis.

  • Bone homeostasis is maintained by co-ordination of bone-resorbing osteoclasts and bone-forming osteoblasts. Imbalance between osteoclasts and osteoblasts leads to many bone diseases such as osteoporosis, rheumatoid arthritis. Taxillus chinensis is a herb that has been widely used to improve bone health. However, the effect and mechanism of Taxillus chinensis extract on osteoclast differentiation and bone resportion has been unknown. Thus, We investigated the effect of Taxillus chinensis on expression of receptor activator of nuclear factor-${\kappa}B$ ligand (RANKL)-induced osteoclast differentiation and bone resorption. Also, the action of Taxillus chinensis on mechanisms relating to osteoclast differentiation was studied. In this results, we identified that Taxillus chinensis significantly inhibited RANKL-induced osteoclast differentiation and bone resportion. Moreover, Taxillus chinensis was suppressed the activation of NF-${\kappa}B$ in bone marrow macrophage treated RANKL and M-CSF. Taxillus chinensis was down-regulated the mRNA expression of c-Fos, nuclear factor of activated T-cells (NFAT)c1, osteoclast-associated receptor (OSCAR), tartrate-resistant acid phosphatase (TRAP). The cell adhesion-related molecules such as integrin ${\alpha}v$ and integrin ${\beta}3$, and the filamentous actin (F-actin) rings of mature osteoclasts-related molecules such as dendritic cell-specific transmembrane preotein (DC-STAMP) and cathepsin K are also suppressed. Taken together, these results indicated that Taxillus chinensis will be a good candidate to treat osteoclast-mediated bone diseases.

  • Objectives : The purpose of this study was find out the therapeutic effects of its exclusive use on the rat with allergic rhinitis. Materials and Methods : Thirty Sprague-Dawley rats were divided into three group : normal group, control group and sample group. To induce the allergic rhinitis in control group and sample group, rats were sensitized intraperitoneally with 0.1% ovalumin solution 3 times at intervals of 1 week. Then intranasal sensitization was performed by diffusing 0.1% ovalumin solution 3 times at intervals of 2 days. After that time, rats in the sample group were administered by $Yonghyang$($LI_{20}$) subcutaneously to treat the inflammation. Results : 1. The anti-oxidant effects of $Hwangryunhaedok-tang$ extract was dose-dependantly increased. 2. The RAW 264.7 cells were treated with LPS for 1 hours prior to the addition of indicated concentrations ($0.4,-1.0mg/m{\ell}$) of HHT, and the cells were further incubated for 24 hours. The LPS-induced iNOS mRNA expression and NO production were dose-dependantly decreased in HHT treated RAW 264.7 cells. 3. The number of eosinophil in HP noticeably decreased than CON and this decrease had probability. The infiltration of eosinophil in HP noticeably decreased than CON. 4. The damaged mucosa as disruption of cilia in respiratory cell and vacant mucose secreting cell were increased CON, but HP same as normal configuration. Decrease of PAS positive cell were shown in CON, but goblet cell occupied with neutral mucous were shown in HP. Decrease of mucosal stress(HSP70). Decrease of perennial sign(PPAR-${\gamma}$). Decrease of icthing and sneezing intricate neurotransmitter-(substance P). 5. The anti-inflammation of HHT pharmacopuncture for AR caused mucosa comes to result as belows. Decrease of pre-inflammation cytokine(TNF-${\alpha}$). Decrease of transcription factor (NF-${\kappa}B$ p65). Decrease of transcription factor inhibitor(p-$I{\kappa}B$). Decrease of inflammation cytokine(iNOS). Conclusions : The results may suggest that administration treatment using $Hwangryunhaedok-tang$ pharmacopucnture decreases the inflammatory response on an animal model with allergic rhinitis.

  • This study was performed to investigate the protective effects of acupuncture on the liver in the oxidative stress caused by cadmium accumulation. Sprague-Dawley male($150{\pm}30g$) rats were stabilized for a week and divided into 5 groups which is normal, control, $LR_3$ acupuncture, $BL_{23}$ acupuncture and sham acupuncture group. For three days experimental groups were received oral doses of cadmium 2 mg/kg twice a day. Acupuncture was given bilaterally at each point 10 times for two weeks. The depth of stimulation was 1 mm at right angles and torsion of acupuncture was produced 2 times per second for 1 minutes. The liver was shipped off and taken weight at the last day of two weeks, and hepatic functions was confirmed through alanine transaminase(ALT) and aspartate amino-transferase(AST). We measured reactive oxygen species of serum, liver and kidney, and compared expression levels of superoxide dismutase(SOD), catalase, glutathione peroxidase(Gpx), nuclear factor erythroid derived 2-related factor 2(Nrf-2), heme oxygenase-1(HO-1), nuclear factor-${\kappa}B$ (NF-${\kappa}B$), cyclooxygenase-2(COX-2), inducible nitric oxide synthase(iNOS), Bax and Cytochrome c. $BL_{23}$ acupuncture group significantly increased liver weight and decreased ALT compared to control group. For the oxidative stress, $LR_3$ acupuncture group significantly reduced reactive oxygen species, and $BL_{23}$ acupuncture group significantly reduced reactive oxygen species and inflammation-related protein compared to control group. But $LR_3$ acupuncture group and $BL_{23}$ acupuncture group didn't significantly reduce apoptosis-related protein. Therefore $LR_3$ and $BL_{23}$ acupuncture showed the effects of antioxidant and anti-inflammatory, especially $BL_{23}$ acupuncture was more effective than $LR_3$ acupuncture on the protection of liver in the oxidative stress.

  • Objectives : This study was performed to investigate the effects of $LR_3$ and $SP_6$ acupuncture on renal damage in streptozotocin(STZ)-induced diabetic mice. Methods : ICR male mice were stabilized for a week and divided into four groups: a normal mice group(N), no-acupuncture diabetic mice group(Control), $LR_3$ acupuncture diabetic mice group($LR_3$), and $SP_6$ acupuncture diabetic mice group($SP_6$). Diabetes was experimentally induced by intraperitoneal injection of STZ(150 mg/kg) in citrate buffer(pH 4.5). For two weeks, $LR_3$ and $SP_6$ acupunctures were administered bilaterally at each point once a day. After two weeks, the animals' weight was measured and they underwent a laparotomy. Serum glucose and blood urea nitrogen(BUN) were measured from the blood taken from the heart. We measured glucose, reactive oxygen species(ROS), peroxynitrite($ONOO^-$) and thiobarbituric acid reactive substances(TBARS) in the kidney and compared expression levels of superoxide dismutases(SOD), glutathione peroxidase(GPx), nuclear factor-kappa B(NF-${\kappa}B$), cyclooxygenase-2 (COX-2), inducible nitric oxide synthase(iNOS) and Interleukin-1 beta(IL-$1{\beta}$). Results : BUN significantly decreased in $LR_3$, $SP_6$ compared to the control group. $LR_3$ showed significantly decreased glucose compared to the control group. $LR_3$, $SP_6$ significantly decreased in ROS and $ONOO^-$ compared to the control group. $LR_3$ significantly decreased in TBARS compared to the control group. $SP_6$ significantly increased in expressions of SOD-1, catalase, and GPx compared to the control group. $LR_3$, $SP_6$ significantly decreased in COX-2 compared to the control group. $SP_6$ significantly decreased in IL-$1{\beta}$ compared to the control group. Conclusions : This study suggests that $LR_3$ acupuncture may be effective in controlling glucose and lipid peroxidation and that $SP_6$ acupuncture may have anti-oxidative and anti-inflammatory effects on renal damage in STZ-induced diabetic mice.
