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.

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.

약용식물 6종을 메탄올로 추출한 다음, n-hexane층을 DMSO에 녹여 항산화 활성을 측정 비교하여 기능성 소재인 천연 항산화제로써의 활용 가능성을 조사하였다. DPPH를 이용한 라디칼 소거능 실험에서는 250 ${\mu}g/mL$ 농도에서 보골지가 대조군인 ascorbic acid에 비해 높은 유리기 소거능에 의한 항산화 활성을 나타냈다. 농도 500 ${\mu}g/mL$에서는 ascorbic acid가 가장 높은 항산화 활성을 보였다. ABTS 유리기 소거능 실험에서는 농도 증가에 따른 항산화 활성이 DPPH assay와 상반된 결과를 나타냈고, 특히 보골지의 항산화 활성이 대조군인 ascorbic acid보다 유의적으로 높게 나타났다. DPPH 라디칼, ABTS 유리기 소거능 실험 결과 공통적으로 우수한 것으로 조사 된 약용 식물은 반지련, 보골지이며 500 ${\mu}g/mL$ 이상의 농도에서 ascorbic acid와 유사한 90% 활성을 보였으며 750 ${\mu}g/mL$ 농도에서는 ascorbic acid 보다 우수한 유리기 소거 활성을 보였다. 따라서, 반지련과 보골지는 항산화 활성이 우수하므로 천연 식물소재로 이용하기에 적합하며, 천연물의 추출 부위, 용매, 추출 조건에 따라 다양한 항산화 활성 능력을 기대 할 수 있으므로 천연 항산화제로서의 응용 가능성 또한 있을 것으로 사료된다.
