Objectives The purpose of this study was to evaluate the effect of Jeopgolsan (JGS) extract on anti-oxidant, anti-inflammatory activities in RAW 264.7 cells and on factors related with fracture healing in skull fractured rat. Methods Experimental animals were divided into four groups: normal group without any treatment (Normal), contral group were treated orally with distilled water (Control), Experimental group were treated orally with JGS at a concentration of 200 mg/kg/day (JGS 200) and Experimental group were treated orally with JGS at a concentration of 200 mg/kg/day (JGS 400). Rats in each group except the normal group were induced fractures in the skull. The 1,1-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid (ABTS) radical scavenging activity were measured to evaluate antioxidant activity. The production of nitric oxide (NO), $interleukin-1{\beta}$ ($IL-1{\beta}$), interleukin-6 (IL-6) and tumor necrosis $factor-{\alpha}$ ($TNF-{\alpha}$) in the RAW 264.7 cells were measured to evaluate anti-inflammatory activity. The production of osteocalcin calcitonin, carboxy-terminal telepeptides of type II collagen (CTX II), transforming growth $factor-{\beta}$ ($TGF-{\beta}$), bone morphogenetic protein-2 (BMP-2), Insulin and alkaline phosphatase (ALP) in serum of rats were measured to evaluate the effects of fracture healing at 0, 2, 4, and 6th week. X-rays were taken every 3 week from 0 to 6th week to evaluate fracture healing effect. Results 1. No cytotoxicity was observed. 2. DPPH and ABTS radical scavenging activity were increased in a concentration dependent manner, indicating anti-oxidant effect. 3. NO, $IL-1{\beta}$, IL-6, and $TNF-{\alpha}$ were not significantly changed, indicating no anti-inflammatory effect. 4. Osteocalcin, Calcitonin, $TGF-{\beta}$ and ALP were significantly increased in the experimental groups. 5. CTX II, insulin were significantly decreased in the expermental groups. 6. Radiologic examination showed that union of fracture was promoted. Conclusions From above results, JGS showed significant results in factors related with fracture healing and radiologic examination. Threfore, JGS is expected to be effective in the treatment of fracture.

This study was initiated in order to investigate the anticancer and immunomodulating activities of crude polysaccharides extracted in methanol, neutral saline, and hot water (hereinafter referred to as Fr. MeOH, Fr. NaCl, and Fr. HW, respectively) from the fruiting bodies of Panellus serotinus. Content of ${\beta}$-glucan and protein in Fr. MeOH, Fr. NaCl, and Fr. HW extracts of P. serotinus ranged from 22.92~28.52 g/100 g and 3.24~3.68 g/100 g, respectively. In vitro cytotoxicity tests, none of the various fractions of crude polysaccharides were cytotoxic against sarcoma 180, HT-29, NIH3T3, and RAW 264.7 cell lines at the tested concentration. Intraperitoneal injection with crude polysaccharides resulted in a life prolongation effect of 23.53~44.71% in mice previously inoculated with sarcoma 180. Treatment with Fr. HW resulted in an increase in the numbers of spleen cells by 1.3 fold at the concentration of $50{\mu}g/mL$ compared with control. Treatment with Fr. NaCl resulted in improvement of the immuno-potentiating activity of B lymphocytes by increasing the alkaline phosphatase activity by 1.4 fold, compared with control, at the concentration of $200{\mu}g/mL$. Among the three fractions, maximum nitric oxide ($13.48{\mu}M$) was recorded at $500{\mu}g/mL$ in Fr. HW. Production of tumor necrosis factor alpha, interleukin-$1{\beta}$, and interleukin-6 was significantly higher, compared to the positive control, concanavalin A, at the tested concentration. Therefore, treatment with crude polysaccharides extracted from the fruiting body of P. serotinus could result in improvement of antitumor activity.

The importance of the kidney in the development of hypertension was first demonstrated by Goldblatt and his colleagues more than fifty years ago. Many hormones and other regulatory factors have been proposed to play a major role in the development of hypertension. Among these factors angiotensia II (ANG II) is closely involved in renal hypertension development since it directly regulates $Na^+$ reabsorption in the renal proximal tubule. Thus the aim of the present study was to examine signaling pathways of low dose of ANC II on the $Na^+$ uptake of primary cultured rabbit renal proximal tubule cells (PTCs) in hormonally defined seum-free medium. The results were as follows: 1) $10^{-11}$ M ANG II has a significant stimulatory effect on growth as compared with control. Alkaline phosphatase exhibited significantly increased activity. However, leucine aminopeptidase and ${\gamma}-glutamyl$ transpeptidase activity were not significant as compared with control. In contrast to $10^{-11}$ M ANG II stimulated $Na^+$ uptake $(108.03{\pm}2.16% of that of control)$, $10^{-9}$ M ANG II inhibited ($92.42{\mu}2.23%$ of that of control). The stimulatory effect of ANG II on $Na^+$ uptake was amiloride-sensitive and inhibited by losartan (ANG II receptor subtype 1 antagonist) and not by PD123319 (ANG II receptor subtype 2 antagonist). 2) Pertussis toxin (PTX) alone inhibited $Na^+$ uptake by $85.52{\pm}3.52%$ of that of control. In addition, PTX pretreatment prevented the AMG II-induced stimulation of $Na^+$ uptake. 8-Bromoadenosine 3',5'-cyclic monophosphate (8-Br-cAMP), forskolin, and isobutylmethylxanthine (IBMX) alone inhibited $Na^+$ uptake by $88.79{\pm}2.56,\;80.63{\pm}4.38,\;and\;84.47{\pm}4.74%$ of that of control, respectively, and prevented the ANG II-induced stimulation of $Na^+$ uptake. However, $10^{-11}$ M ANG II did not stimulate cAMP production. 3) The addition of 12-O-te-tradecanoylphorbol-13-acetate (TPA, 0.01 ng/ml) to the PTCs produced significant increase in $Na^+$ uptake ($114.43{\pm}4.05%$ of that of control). When ANG II and TPA were added together to the PTCs, there was no additive effect on $Na^+$ uptake. Staurosporine alone had no effect on $Na^+$ uptake, but led to a complete inhibition of ANG II- or TPA-induced stimulation of Na'uptake. ANG II treatment resulted in a $111.83{\mu}4.51%$ increase in total protein kinase C (PKC) activity. In conclusion, the PTX-sensitive PKC pathway is the main signaling cascade involved in the stimulatory effects of ANG II on $Na^+$ uptake in the PTCs.

Osteoporosis is social problem around the world, because fracture of old age may lead to critical medical condition. Osteoclast is a main target for prevention and treatment of osteoporosis due to their responsibility for bone resorption. Saussureae Radix has been known that has gastro-protective, bronchodilatory effect and has a anti-biotic effect. Saussureae Radix has been widely used in Oriental medicine. However, the effect of extract of Saussureae Radix in osteoclast differentiation remains unknown. Thus, we examined the effect of Saussureae Radix in receptor activator of nuclear factor-${\kappa}$B ligand (RANKL)-induced osteoclast differentiation. From the results of our study, Here we found that Saussureae Radix significantly inhibited osteoclast differentiation induced by RANKL. Saussureae Radix suppressed the activation of NF${\kappa}$B in bone marrow macrophages (BMMs) treated with RANKL. Also, Saussureae 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, Saussureae Radix greatly inhibited the protein expression of c-fos and NFATc1. especially in the case of NFATc1 expression, a master transcription factor of the differentiation of osteoclasts is very important step for osteoclastogenesis. These results demonstrate that Saussureae Radix may be useful treatment option of bone-related disease such as osteoporosis and rheumatoid arthritis.

The aim of this study was to investigate the safety of short-term use of Korean herbal medicine (KHM; prescribed herbal medicine by doctors of traditional Korean medicine) on liver function. Three hundred eighty four outpatients who took KHM for various conditions were enrolled for multi-center, prospective observational study. Of them 237 patients completed questionnaire and were checked liver function (aspartic aminotransferase;AST, alanine aminotransferase;ALT, alkaline phosphatase;ALP, total bilirubin;t-Bil, direct bilirubin;d-Bil, gamma glutamyltranspeptidase;GGT, protein and albumin) before and after taking KHM (duration; 21.4${\pm}$10.0 days), and data were analysed statistically. Of the 213 patients showing normal liver function test (LFT) at baseline, 209 (98.1%) remained within the normal range at the second test while 3 (1.4%) revealed slight increase of LFT. Only one subject had raised LFT regarding level of liver injury without perceived symptoms. Twenty-four of 237 patients were abnormal at baseline, and 16 at the second testing. Of the patients taking KHM, only 4 changed from normal to abnormal while 12 from abnormal to normal in their LFT. There were no significant increase in LFT level between the first and second test, except in the t-Bil level, however, the change of t-Bil was small and within normal range. The current study showed that the use of KHM did not increase the frequency of abnormal LFTs, at least in the short term.

This study was conducted to investigate the effects of dietary Allium hookeri on growth performance, bone strength, and blood biochemical profiles in growing broiler chickens. Twelve hundreds of one-day old Arbor Acres male broilers were divided into 6 treatments with 4 replicates and 50 birds per replicate (n=200 chicks/treatment). Chickens fed basal diet (Control), basal diet with commercial X (Positive control) at 0.05% of diet, or each one of the experimental diets (L3, L5, R3, R5) supplemented with the powder of A. hookeri leaf or root at 0.3 and 0.5% of diet respectively for 5 weeks. At the 5th week of feeding the diets, body weight, tibia strength, and blood biochemical profiles including antibody titers were measured. Dietary A. hookeri (L3, L5, R3, R5) significantly increased final body weight than the control group. And the dietary leaf of A. hookeri effectively increased the growth performance than dietary root of A. hookeri. Interestingly dietary leaf of A. hookeri improved tibia strength than the control group and L3 showed the highest value. The antibody titers against infectious bursal disease (IBD) increased with the addition of dietary leaf of A. hookeri compared with positive control, R3, and R5 groups. But there was no significant difference in serum biochemical parameters such as albumin, globulin, glucose, cholesterol, Ca, P, total protein, total bilirubin, alanine aminotransferase, alkaline phosphatase, and gamma-glutamyl transferase. These results suggest that A. hookeri can be used as a good supplement to improve growth performance and health by increasing bone strength and antibody titer against IBD without any anti-nutritional or toxic effects in growing broilers.

To prevent and treat the osteoporotic fracture, more attention should be paid in old age patients. Osteoclast which has ability to bone resorption is originated from hematopoietic cell line and plays a key role osteoporotic bone loss. Rubi Fructus has been widely used in Oriental medicine. Extracts of the leaves and fruit of Rubus species have been used in various countries as natural remedies to treat diabetes, infections, colic, and burns. However, the effect of extract of Rubi Fructus (fruit of Rubus coreanus Miq.) in osteoclast differentiation remains unknown. Thus, we evaluated the effect of Rubi Fructus on receptor activator of nuclear factor-kB ligand (RANKL)-induced osteoclast differentiation. Here we found that Rubi Fructus significantly inhibited osteoclast differentiation induced by RANKL. Rubi Fructus suppressed the activation of p38 pathway and NFkB in bone marrow macrophages (BMMs) treated with RANKL. Also, Rubi Fructus 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, Rubi Fructus greatly inhibited the protein expression of c-fos and NFATc1. especially in the case of NFATc1 expression, a master transcription factor of the differentiation of osteoclasts is very important step for osteoclastogenesis. Taken together, our results demonstrated that Rubi Fructus may be useful treatment option of bone-related disease such as osteoporosis and rheumatoid arthritis.

The present study was undertaken to compare the variation on serum biochemical values by storage in the rats. Sera were prepared from 30 Sprague-Dawley rats of each sex. 5 aliquots from each serum were placed in a -80$^{\circ}C$ freezer with the exception of I aliquots which was analyzed immediately. The analysis was performed on the following months; 1, 2, 3, 6, and 12 months after freezing. The parameters measured) were aspartate aminotransferase(AST), alanine aminotransferase(ALT), alkaline phosphatase(ALP), blood urea nitrogen(BUN) creatinine(CRE), glucose(GLU), total cholesterol(TCHO), triglyceride (TG), total protein(TP), albumin(ALB), total bilirubin(TBIL), calcium(Ca$\^$＋＋/), inorganic phosphorus(IP), creatine kinase (CK), phospholipid(PL), albumin-globulin ratio(A/G), sodium(Na$\^$＋/), potassium(K$\^$＋/), and chloride(Cl$\^$－/) The statistical analysis with Repeated Measures ANOVA, did not show statistical significance in the parameters of AST, ALT, BUN, TG, CK, A/G, Na$\^$＋/ of 1 month freezed sera, in those of AST, TG, CK, K$\^$＋/) of 2 month freezed sera, in those of AST, ALT, BUN, CRE, TCHO, TP, TBIL, CK, PL, Na$\^$＋/), K$\^$＋/), Ct on month fteezed sera, in those of Cl$\^$－/ of 6 month fteezed sera, and in those of ALT, TG, ALB of 12 month freezed sera in male SD rats. On the other hand, it did not show statistical significance in the parameters of AST, ALT, ALP, BUN, GLU, TCHO, TG, TBIL, CK, PL, A/G, Na$\^$＋/ of 1 month freezed sera, in those of AST, TCHO of 2 month freezed sera, in those of AST, BUN, CRE, TCHO, TP, TBIL, CK, PL of 3 month freezed sera, in those of TCHO, IP, PL of 6 month freezed sera, and in those of ALB of 12 month freezed sera in female SD rats. On the basis of the results, although there are some statistical variations in the biochemical values of the sera, it is suggested that if sera are analysed at the same time before 12 months storage in a －80 $^{\circ}C$ freezer, the storing time does not affect the biochemical evaluation of the sera in SD rats.
