  • Purpose: We evaluated whether Spatholobus suberectus extract (SSE) can be used as a means of preventing and treating osteoporosis by measuring its effect on osteoclast differentiation, gene expression, and bone resorption. Methods: SSE was used to examine the effect on RAW 264.7 cells stimulated with RANKL to induce bone resorption. The inhibitory effect of TRAP formation and the expression of the bone resorption factors TRAP, cathepsin K, and MMP-9 during differentiation were measured. The effects on the differentiation-related factors NFATc and TRAIL and on the expression of OC-STAMP, DC-STAMP, ATP6v0d2, MITF, c-Fos, and inflammation-related factors were also evaluated. The effect on bone resorption was evaluated by culturing RANKL-treated osteoclasts on artificial bone fragments and observing the resulting resorption traces. The effect on bone damage in experimental animals was also measured. Results: SSE inhibited the differentiation of RANKL-stimulated osteoclasts into osteoclasts and suppressed the expression of cathepsin K, TRAP, MMP-9, NFATc1, TRAIL, MITF, OC-STAMP, DC-STAMP, ATP6v0d2, and c-Fos genes. Bone pore formation due to osteoclast action was also inhibited, and LPS-induced bone loss was suppressed in animal experiments. Conclusions: SSE could be useful for the prevention or treatment of osteoporosis by inhibiting osteoclast differentiation and bone resorption and suppressing bone loss induced in experimental animals. However, studies of larger populations are required.

  • This study was performed to identify safe natural food preservatives from medicinal herbs and to evaluate the antimicrobial effects of medicinal plants against microorganisms. Medicinal herbs were extracted 3 times with methanol at $45^{\circ}C$ for 3 h and fractionated with n-hexane. The antimicrobial effects of the fractions were determined by measuring the diameter of the inhibition zone by using an agar-well diffusion assay. The MIC of fractions for the inhibition of microorganisms was determined using a microplate reader. The antimicrobial effects of fractions were greater against gram positive bacteria than against gram negative bacteria, but the difference was not significant. The antimicrobial effects of fractions were concentration dependent. While these results have implications, the underlying mechanisms of microbial inactivation need to be further elucidated. The results showed the possibility of developing safer food preservatives.

  • To investigate the antioxidant capacity of traditional Korean medicines, water extracts from 57 species were tested on their antioxidant activity using radical scavenging effects against ABTSㆍ+. Of which, Rhus javanica, Caesalpinia sappan, Rosa rugosa, Spatholobus suberectus, and Magnolia obovata showed strong antioxidant capacities at 10㎍ concentration. Therefore, antioxidant capacities of 5 traditional medicine extracts in the different concentration (1㎍, 5㎍, and 10㎍) were determined. The 5 traditional medicine extracts was detected in antioxidant capacity dose dependently. R. javanica was showed the highest antioxidant capacity, the antioxidant activity at 1 ㎍ of herbal extract being 0.85 mM TE. At the same time, the antiperoxidation effects of these 5 medicines were determined. Lipid peroxidation in brain homogenates induced by NADPH and ADP-Fe/sup 2+/ was strong inhibited by S, suberectus, R. rugosa, and M. obovata. Extract of C. sappan was showed the highest inhibition against lipid peroxidation compared with 4 herbal extracts in vitro. These traditional medicines are a potent antioxidant capacity and antiperoxidation activity, further investigation into the in vivo antioxidant therapeutic potential for treatment of human disorders such as Alzheimer's disease.

  • Ras proteins play an important role in intracellular signal transduction pathways involved in cell growth and the mutated twas genes have been found in thirty percent of human cancers. Ras proteins (H-, K- and N-Ras) are small guanine nucleotide binding proteins that undergo a series of posttranslational modifications including the farnesylation onto cysteine 186 at C-terminal of Ras by farnesyl protein transferase (FPTase). This is a mandatory process for retention of transforming ability. Therefore, inhibitors of FPTase have a promising to be effective antitumor agents. In our screening program for FPTase inhibitors, the methanol extracts of 193 plants were screened for the inhibitory activity against FPTase partially purified from the rat brain. Extracts of 7species plants including Areca catechu, Saururus chinensis, Curcuma longa, Artemisa princeps, Paeonia suffruticosa, Spatholobus suberectus, Cinnamomum cassia, Cinnamomum japonicum inhibited more than 60% of FPTase activity at a concentration of $100\;{\mu}g/ml$.

  • Objectives : Recently there have been encouraging results, from a western perspective, in the cancer research field regarding the anticancer effects of herbal medicine. This paper was aimed to review herbal medicine playing its anticancer role in terms of apoptosis, inflammation control, differentiation and telomerase. Methods : New studies for tang, medicinal herb itself or effective ingradients of medicinal herb showing anti-cancer effectiveness were reviewed and summarized in terms of pharmacological action. Results : Ethanol extracts of $Spatholobus$ $suberectus$ greatly inhibited cancer cell growth inducing cell apoptosis and cytotoxic effects. $Scutellaria$ $baicalensis$ may be responsible for its anticancer activity showing inhibition of $PGE_2$ synthesis via suppression of COX-2 expression. Saikosaponins isolated from $Bupleurum$ induced the differentiation of C6 glioma cells, cancer cells, into astrocytes, normal cells. Acetone extract of $Bupleurum$ $scorzonerifolium$ inhibited proliferation of human lung cancer cells via inducing apoptosis and suppressing telomerase activity. Conclusions : Herbal medicine inhibited cancer cell growth inducing cell apoptosis and cytotoxic effects. Inflammation persisting for a decade eventually elevates the risk of cancer sufficiently that it is discernible in case control epidemiological studies. Differentiation therapy is defined as a therapy to treat cancers by inducing differentiation of the stem cells. Telomerase expression is a hallmark of cancer. Nearly the complete spectrum of human tumors has been shown to be telomerase positive.

  • Objectives: Spatholobi Caulis is the stem of Spatholobus suberectus Dunn., which has been used for treating menstrual disorders, anemia, and rheumatic arthralgia in traditional Oriental medicine, This study was conducted to evaluate the inhibitory effects of Spatholobi Caulis extract (SCE) on the production of nitric oxide (NO) and pro-inflammatory cytokines in LPS-activated Raw264,7 cells. Methods : Cell viability was determined by MIT assay. Relative levels of NO were measured with Griess reagent and pro-inflammatory cytokines were detected by ELISA Expression of iNOS and COX-2 proteins were determined by western blotting. Results : NO production and iNOS expression were increased by incubation with LPS for 24 h. However, the augmented NO was reduced by SCE in a dose-dependent manner. Expressions of iNOS and COX-2 were inhibited by the treatment with SCE, SCE also suppressed the production of pro-inflammatory cytokines, such as IL-1beta and IL-6. Conclusions : These results indicate that the MeOH extract of Spatholobi Caulis warrant further development as an anti-inflammatory agent for the treatment of Gram-negative bacterial infections.

  • The objective of this study was carried out in order to evaluate the antioxidative activities of n-hexane fractions from medicinal herbs. Certain parts from 6 species of edible and medicinal herbs were extracted with methanol. Radical scavenging activity of the n-hexane fractions against DPPH and ABTS radicals were observed to be high in Psoralea corylifolia, and Scutellsria barbata; it also significantly increased (p<0.05). For a comparison of the effect of various concentration of fractions, as the concentration of treatment increased, the antioxidative effects on radical scavenging activity also oncreased; yet it was not significant. The antioxidative effect of medicinal plants was dependent on the concentration but was not significant. Therefore, these results indicate that edible wild plants, such as Psoralea corylifolia, and Scutellsria barbata may be useful as potential antioxidant sources for improving the human antioxidant defense system against disease.
