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.

Objectives : The purpose of this Study was to identify the effect of Dokhwalgisaeng-tang(Duhuoqisheng-tang) and Jungsongouhyul pharmacopuncture on pain control and nerve regeneration after crush injury in rat sciatic nerve. Methods : Neuropathic pain was induced by crush-induced model of right sciatic nerve. Animal groups were divided as follows; Group I: no treatment control group, Group II : experimental group treated with Dokhwalgisaeng-tang(Duhuoqisheng-tang), Group III : experimental group treated with Jungsongouhyul pharmacopuncture, and Group IV : experimental group treated with Dokhwalgisaeng-tang(Duhuoqisheng-tang) and Jungsongouhyul pharmacopuncture. To evaluate pain intensity, each group was observed paw withdrawal threshold and immunoreactivity on the c-fos before and after respective treatments in five hours, first, third, and fifth day. To evaluate nerve regeneration, those were observed SFI(Sciatic Functional Index) and GAP-43(Growth Associated Protein 43) after each treatment in seventh and thirteenth day. Results : 1. Paw withdrawal threshold to the mechanical stimuli made the significant difference between group IV and the control group after five days of the experiment. 2. Paw withdrawal threshold to the thermal stimuli made the significant difference between group I and III, I and IV, II and IV. 3. In immunohistochemical response of c-fos, as time passes, the immunoreactivity of all groups was decreased gradually. Especially, group IV was observed the lowest after three days. 4. The differences of sciatic function indexes in each group were significantly between group I and III, I and IV, II and IV after 14 days, and between group I and III, I and IV, II and IV, III and IV after 21 days. 5. In immunohistochemical response of GAP-43, all groups had higher GAP-43 immunoreactivity at the 14 days from post-injury and group IV showed highest immunoreactivity. Conclusions : Based on above the results, it is proposed that Dokhwalgisaeng-tang(Duhuoqisheng-tang) and Jungsongouhyul pharmacopuncture may be helpful as a treatment in neuropathic pain and nerve regeneration in rat model.

Objectives : The purpose of this investigation is to evaluate the effects of Scutellaria baicalensis GEORGI on alteration in gene expression in a hypoxia model using cultured rat cortical cells. Methods : E18 rat cortical cells were grown in a Neurobasal medium containing B27 supplement. On 12 DIV, Scutellaria baicalensis GEORGI(20 ug/ml) was added to the culture media and left for 24 hrs. On 11 DIV, cells were given a hypoxic insult $(2%\;O_2/5%\;CO_2,\;37^{\circ}C,\;3\;hrs)$, returned to normoxia and cultured for another 24 hrs. Total RNA was prepared from Scutellaria baicalensis GEORGI-untreated (control) and -treated cultures and alteration in gene expression was analysed by microarray using rat 5K-TwinChips. Results : For most of the genes altered in expression, the Global M values were between -0.5 to +0.5. Among these, 1143 genes increased in their expression by more than Global M +0.1, while 1161 genes decreased by more than Global M -0.1. Effects on some of the genes whose functions are implicated in neural viability are as follows: 1) The expression of apoptosis-related genes such as Bad (Global M = 0.39), programmed cell death-2(Pdcd2) (Global M = 0.20) increased, while Purinergic receptor P2X(P2rxl) Global M = -0.22), Bc12-like1(Bc1211)(Global M = -0.19) decreased. 2) The expression of 'response to stress-related genes such as antioxidation-related AMP-activated protein kinase subunit gamma 1 gene (Prkag1) (Global M = 0.14), catalase gene (Global M = 0.14) and Heme Oxygenase(Hmoxl) increased. 3) The expression of Fos like antigen 2 (Fos12) expressed in neurons that survive ischemic insult increased (Global M = 0.97). Conclusions : these data suggest that Scutellaria baicalensis GEORGI increases the expression of antiapoptosis- and antioxidation- related genes in a way that can not yet be explained.

Objectives : The aim of this study was to investigate whether the extract of Coptidis Rhizoma inhibits inflammation in chronic cold stress (CCS)-exposed mice or not. Methods : Coptidis Rhizoma extract (CRE) was made by reflux with distilled water. Male ICR mice (7 weeks old) were divided randomly into 5 groups: (1) control, (2) CCS, (3) CCS+CRE 100 mg/kg, (4) CCS+CRE 300 mg/kg, (5) CCS+CRE 1,000 mg/kg groups. Mice were orally administered once a day for 14 days starting from 1 day before CCS. Group (2)-(5) were exposed to CCS conditions that maintained at $4^{\circ}C$ for 2 h once a day for 14 days. The levels of serum cortisol and hypothalamic prostaglandin E1 (PGE1) and PGE2 were measured by enzyme-linked immunosorbent assay kit. The expression levels of several pro-inflammatory factors like heat shock protein 70 (HSP70), c-fos, and nuclear factor kappa-light-chain-enhancer of activated B cells (NF-kB) were measured by western blot analysis in mouse hypothalamus. Results : Oral administration of CRE 1,000 mg/kg significantly suppressed the increase of serum cortisol levels in mice exposed to CCS. CCS-exposed mice had significantly increased the expression of HSP70, c-fos, and NF-kB in hypothalamus, while CRE treatment significantly attenuated the elevation of these pro-inflammatory factors. The ratio of PGE2/PGE1 was also higher in CCS-exposed mice than control group. CRE treatment significantly reduced the increase of PGE2/PGE1 ratio induced by CCS. Conclusion : These findings suggest that Coptidis Rhizoma may work as a potential agent to modulate inflammatory responses under the condition of cold adaptation formed by CCS.
