  • Anemarrhenae Rhizoma (AR) is used in traditional oriental medicine for various medicinal purposes. However, the exact mechanism that accounts for the anti-allergy and anti-inflammatory effects of the AR is still not fully understood. The aim of The present study is to elucidate whether and how AR modulates the allergic reactions in vivo, and inflammatory reaction in vitro. In this study, we showed that AR significantly decreased compound 48/80-induced systemic anaphylaxis, paw oedema, and histamine release from preparation of rat peritoneal mast cells. Also, AR inhibited the expression of inflammatory cytokine in PMA plus A23187-stimulated human mast cells (HMC-1). In addition, we showed that anti-inflammatory mechanism of AR is through suppression of nuclear factor-${\kappa}B$ activation $I{\kappa}B-{\alpha}$degradation. These results provided new insight into the pharmacological actions of AR as a potential molecule for therapy of inflammatory allergic diseases.

  • Soyangin-Hyeongbangpaedok-san(SHBPDS) is a herbal formula used for the common cold or upper respiratory illness. In order to investigate the effect of SHBPDS, mice were orally administered with SHBPDS alcohol extract for 7 days followed by intravenous anti-CD3 injection. In addition, splenocytes and CD4 T cells were cultured with SHBPDS in response to anti-CD3 in vitro and cytokines and transcription factors were evaluated. In vivo treatment with SHBPDS significantly augmented the expressions of the percentage of CD4 T cells and CD 69, an indicator of early T cell activation. Serum levels of IL-4 were significantly increased but those of IFN-${\gamma}$ and IL-2 did not reach statistical significance. The expressions of IFN-${\gamma}$ and T-bet mRNA were significantly downregulated in SHBPDS treated mice while those of IL-4 and C-Maf were significantly upregulated. In vitro stimulation of splenocytes and CD4 T cells by SHBPDS resulted in a reduction in IFN-${\gamma}$ secretion and STAT4 activity. The IL-4 releases from both cells were slightly reduced, but STAT6 activity was rather increased. In conclusion, SHBPDS exerted an inhibition in the expression of IFN-${\gamma}$, T-bet and STAT4 while IL-4, C-Maf and STAT6 were increased. Further studies are required to examine its pharmacological effects using more appropriate animal experiments.

  • Bone homeostasis is maintained by balance between bone resorbing-osteoclasts and bone forming-osteoblasts. Excessive osteoclastic bone resorption plays a critical role in bone destruction in pathological bone diseases such as osteoporosis, rheumatoid arthritis, and periodontal disease. Many compounds derived from natural products have pharmacological applications and have therapeutic value for treating or preventing several bone diseases characterized by excessive bone resorption. To discover new compounds that can act as anti-resorptive agents, we screened for natural compounds that regulate osteclast differentiation, and found that water extract of Ziziphus Jujuba Mill (WEZJ) has inhibitory effects on osteoclast differentiation. In this study, WEZJ clearly inhibits the osteoclast differentiation in the presence of receptor activator of nuclear factor kB (RANKL), macrophage colony-stimulating factor (M-CSF) without cytoxicity by blocking activation of nuclear factor of activated T cells (NFAT)c1, and c-Fos. In signaling pathway, the phosphorylation of Akt, p38, c-Jun N-terminal kinases (JNK), extracellular signal-regulated kinases (ERK) and the expression of osteoclast-associated receptor (OSCAR), tartrate-resistant acid phosphates (TRAP), Integrin av, Integrin b3, Cathepsin K are suppressed, too. These result suggest that WEZJ may have therapeutic value for treating or preventing several bone diseases characterized by excessive bone destruction.

  • ${\alpha}$-Asarone exhibits a number of pharmacological actions including neuroprotective, anti-oxidative, anticonvulsive, and cognitive enhancing action. The present study investigated the effects of ${\alpha}$-asarone on pro-inflammatory cytokines mRNA, microglial activation, and neuronal damage in the hippocampus and on learning and memory deficits in systemic lipopolysaccharide (LPS)-treated C57BL/6 mice. Varying doses of ${\alpha}$-asarone was orally administered (7.5, 15, or 30 mg/kg) once a day for 3 days before the LPS (3 mg/kg) injection. ${\alpha}$-Asarone significantly reduced TNF-${\alpha}$ and IL-$1{\beta}$ mRNA at 4 and 24 hours after the LPS injection at dose of 30 mg/kg. At 24 hours after the LPS injection, the loss of CA1 neurons, the increase of TUNEL-labeled cells, and the up-regulation of BACE1 expression in the hippocampus were attenuated by 30 mg/kg of ${\alpha}$-asarone treatment. ${\alpha}$-Asarone significantly reduced Iba1 protein expression in the hippocampal tissue at a dose of 30 mg/kg. ${\alpha}$-Asarone did not reduce the number of Iba1-expressing microglia on immunohistochemistry but the average cell size and percentage areas of Iba1-expressing microglia in the hippocampus were significantly decreased by 30 mg/kg of ${\alpha}$-asarone treatment. In the Morris water maze test, ${\alpha}$-asarone significantly prolonged the swimming time spent in the target and peri-target zones. ${\alpha}$-Asarone also significantly increased the number of target heading and memory score in the Morris water maze. The results suggest that inhibition of pro-inflammatory cytokines and microglial activation in the hippocampus by ${\alpha}$-asarone may be one of the mechanisms for the ${\alpha}$-asarone-mediated ameliorating effect on memory deficits.

  • We have studied the physico-chemical change and pharmacological transformation of traditional herbal medicines with processing. Evodia fruit (EF) has processed for the purpose of detoxification and reduction of its bitter taste. There are various methods of processing EF in Oriental medicinal reference. Among them, we processed EF according to the method of Sang-han theory, the most famous medicinal reference. We processed EF with washing in hot water, and then dried. Processed EFs(PEFs) were prepared according to the above procedure through repetition of 1,3,5 and 7 times respectively. The contents of weight loss, water extract, diluted ethanol extract, ether extract, total ash, acid insoluble ash, alkaloids and limonin in non-processed EF (NPEF) and PEFs were examined. The weight loss, and contents of water extract and dilute ethanol extract in PEF showed decrease in proportion to increase of washing time, while the contents of ether extract, total ash and acid insoluble ash showed little change as compared with those of NPEF. And the content of evodiamine and rutaecarpine was not changed distinctly. However, the content of limonin decreased in the final processed material in proportion to increase of washing times with hot water. And the intense of bitter taste in PEF was also reduced. These results were ascribed to the flowing-out of the water-soluble portion. The biological activities of NPEF and PEF were also investigated. In the test of DPPH scavenging effect, xanthine oxidase inhibition effect and TBA-Rs effect, PEF was more effective than NPEF in vitro. Also, both NPEF and PEF showed potent analgesic and anti-inflammatory effects against in mice. Especially, PEF by 3 times washing with hot water was more effective than other PEFs. From these results, it is considered that PEF should be prepared by 3 times washing with hot water.

  • It has been known that the mulberry leaf is effective in many diseases. Nowadays, the pharmacological effects on diabetes mellitus of mulberry leaves have been confirmed and they are used for many aspects. And Mulberry leaves are also hewn to be effective in the prevention of diabetics, because of their rich amino acids and fibers. From the results of sensory evaluation, the addition of up to $0.5\%$ MLP(mulberry leaf patty), to the chicken patties induced no significant differences in texture, appearance, and color until $0.5\%$ adding of MLP. However, chicken patties with added $0\%$, and $0.25\%$ added of MLP were shown have the highest acceptability, so these levels were thought to be the proper addition amounts of MLP to the chicken patty. Brightness(L) of these patties was the highest in the $0\%$ group as (55.63) and decreased with increasing adding amount of MLP level. Redness(a) was decreased with increasing adding amount of MLP and appeared as ueenish. Yellowness(b) was the lowest in the $0\%$ MLP addition group as (13.31) and increased with increasing MLP level. Hardness was the highest in the chicken patty with $0.25\%$ added MLP, and the lowest value in the chicken patty with $0.5\%$ added MLP. Cohesiveness was the highest in $0\%$ added MLP added chicken patty and springiness was the highest in $0.5\%$ added MLP added chicken patty. But not significantly. Also Brittleness was similar among the various chicken patties with no significantly difference. As for the composition of fatty acids in the chicken patties with added MLP, saturated fatty acids were decreased and unsaturated fatty acids were increased with increasing MLP Especially, the contents of essential fatty acids showed a largely increasing tendency in the chicken patties with added MLP Linoleic acid, linolenic acid, and arachidonic acid were increased to $9.38mg\%,\;0.65mg\%\;and\;1.28mg\%$, respectively in chicken patty with $1.0\%$ added MLP.

  • Background: In recent years, adjuvants have received increasing attention owing to the development of purified subunit and synthetic vaccines which are poor immunogens and require additional adjuvants to evoke an immune response. Therefore, immunologic adjuvants have been developed and tested. Plant polysaccharides have been recognized as effective biological response modifiers with low toxicity. Methods and Results: In this study, the polysaccharide from the aboveground part of Astragalus membranaceus Bunge containing immunomodulating arabino-3,6-galactan was evaluated for its hemolytic activity and adjuvant potential in the specific cellular and humoral immune responses to ovalbumin. The polysaccharide from the aboveground part of Astragalus membranaceus Bunge was co-immunized with the purified Vi capsular polysaccharide of Salmonella typhi vaccine in mice. The polysaccharide from the aboveground part of Astragalus membranaceus Bunge did not induce any hemolytic activity or side effects at doses up to $500{\mu}g/m{\ell}$. The concanavalin A-, lipopolysaccharide-, and ovalbumin-induced splenocyte proliferation and serum ovalbumin-specific IgG, IgG1 and IgG2b antibody titers in immunized mice were significantly enhanced by AMA. Pharmacological data revealed that the polysaccharide from the aboveground part of Astragalus membranaceus Bunge increased antigen-specific antibody levels in immunized mice. The polysaccharide from the aboveground part of Astragalus membranaceus Bunge-adjuvanted purified Vi capsular polysaccharide of Salmonella typhi vaccine improved the proliferation of splenocytes and macrophages as well as stimulated cytokine production. Conclusions: These results suggest that the polysaccharide from the aboveground part of Astragalus membranaceus Bunge-adjuvanted vaccines enhanced humoral and cellular immunity and that the polysaccharide from the aboveground part of Astragalus membranaceus Bunge is a safe and efficacious adjuvant candidate suitable for use in prophylactic and therapeutic vaccines.

  • Cordycepin은 Cordyceps militaris에서 처음 유래된 nucleoside adenosine 유도체의 일종으로 면역증강 및 항암활성을 포함한 다양한 약리 기능이 있는 것으로 알려져 있다. 본 연구에서는 LNCap 인체 전립선 암세포 모델을 이용하여 cordycepin에 의한 항암활성 기전을 연구하였다. Cordycepin 처리에 따라 LNCap 세포는 처리 농도 의존적으로 증식이 억제되었으며, 이는 apoptosis 유발과 연관성이 있음을 poly ADP-ribose polymerase의 단편화 현상과 Annexin V 염색에 의한 정량적 분석으로 확인하였다. Cordycepin 처리에 따른 flow cytometric analysis 결과로서 cordycepin이 세포주기 G2/M기 정체 현상을 유발하였음을 알 수 있었으며, 이는 cyclin B1 및 cyclin A의 발현 감소와 연관성이 있었다. 또한 cordycepin이 처리된 LNCap 세포에서 cyclin-dependent kinase (CDK) inhibitor p21Waf1/Cip1의 발현이 증가되었지만, CDK2, CDC2 및 Cdc25C의 발현에는 큰 영향을 미치지 않았으며, cordycepin에 의하여 증가된 p21 단백질은 CDK2 및 CDC2와의 복합체를 형성하고 있었다. 본 연구의 결과는 LNCap 전립선 암세포에서 cordycepin에 의한 G2/M 및 apoptosis 유발은 p53 비존적인 CDK inhibitor p21의 발현 증가가 중요한 역할을 하고 있음을 보여주는 것이다.
