  • 천연발효물질인 프로폴리스를 이용하여 숙취 해소 음료를 개발하고 그에 따른 알콜 대사에 미치는 효과를 알아보고자 하였다. 프로폴리스 농축액과 다양한 약용식물의 농축액을 사용하여 숙취 해소 음료를 개발하였다. 배합원료 각각의 알콜 분해 능력을 검토한 결과, 프로폴리스와 가시오가피 추출액이 가장 큰 분해 능력을 보였다. 타 회사 제품과의 알콜 분해 능력을 비교한 경우 급성 주정 중독량 (kg당 4g)을 경구 투여하였을 때 유의적인 차이를 보이지 않았다. 그러나 주정중독량 지표보다 약 1/3을 감소시킨 kg당 1.8 L의 술을 경구 투여한 경우, 프로폴리스 음료는 270분이 경과했을 때 0.026%, 360분이 경과했을 때에는 0.000%의 혈중알콜농도를 나타내었다. 이것으로 보아 프로폴리스 음료는 섭취알콜의 양이 많을 경우에는 큰 차이가 없었지만, 일정량의 알콜을 섭취할 경우에는 매우 뛰어난 알콜 분해 효능이 있음을 알 수 있었다.

  • A strong oxidative stress-inducible peroxidase promoter (referred to as SWPA2 promoter) was cloned from tell cultures of sweetpotato (Ipomoea batatas) and characterized in transgenic tobacco cultured cells in terms of biotechnological applications. Employing a transient expression assay in tobacco protoplasts, with five different 5'-deletion mutants of the SWPA2 promoter fused to the $\beta$-glucuronidase (GUS) reporter gene, the 1314 bp deletion mutant showed approximately 30 times higher GUS expression than the CaMV 35S promoter. The expression of GUS activity in suspension cultures of transgenic cells derived from transgenic tobacco leaves containing the -1314 bp SWPA2 promoter-GUS fusion was strongly expressed following 15 days of subculture compared to other deletion mutants, suggesting that the 1314 bp SWPA2 promoter will be biotechnologically useful for the development of transgenic cell lines engineered to produce key pharmaceutical proteins. In this respect, we developed transgenic cell lines such as tobacco (Nicotiana tabacum L. BY-2), ginseng (Panax ginseng) and Siberian ginseng (Acanthopanax senticosus) using a SWPA2 promoter to produce a human lactoferrin (hLf) and characterized the hLf production in cultured cells. The hLf production monitored by ELISA analysis in transgenic BY-2 cells was directly increased proportional to cell growth and reached a maximal level (up to 4.3% of total soluble protein) at the stationary phase in suspension cultures. The SWPA2 promoter should result in higher productivity and increased applications of plant cultured cells for the production of high-value recombinant proteins.

  • $NF-{\kappa}B$ (nuclear factor-kappa B) plays a particularly central role in epidermal biology. It has been established that ultraviolet radiation (UVR) is one of the mechanisms to induce the activation of $NF-{\kappa}B$ in human skin. We previously demonstrated that melanogenic inhibitors may act through the inhibition of $NF-{\kappa}B$ activation in keratinocytes. In order to find another type of melanogenic inhibitors of $NF-{\kappa}B$ activation, various kinds of the extracts from crude drugs $(30\;{\mu}g/ml)$ were preincubated with transfectant HaCaT cells for 3 hrs and then UVR $(60\;mj/cm^2)$ was irradiated. UVR-exposed cells were incubated for another 6 hrs to measure the $NF-{\kappa}B$ activity. $NF-{\kappa}B$ activation was measured with the secreatory alkaline phosphates (SEAP) reporter gene assay using a fluorescence detection method. Among natural products, Lycium chinense, Acanthopanax senticosus, Angelica koreana, Kalopanax pictus and Asparagus cochinchinensis were the most potent inhibitors of $NF-{\kappa}B$ activation by UVR. These observations suggest that some crude drugs might act partially through the modulation of the synthesis of melanotrophic factors to decrease melanogenesis in keratinocytes.

  • This study was conducted to investigate the effects of Aralia elata, Acanthopanacis cortex and Ulmus davidiana water extracts on blood hemoglobin, $HbA_{1c}$, levels and biomarkers in the streptozotocin (STZ)-induced diabetic rats. Male Wistar rats divided into normal and diabetic groups. The diabetic groups subdivided into the control group (DM) and Araliaceae water extracts supplemented groups: Aralia elata (AE), Acanthopanacis cortex (AC) and Ulmus davidiana (UD). The extracts were supplemented in diet base on 11.42 g of raw Araliaceae/kg diet for 7 weeks. The diabetes was induced by injecting 572 (55 mg/kg B.W., i.p.) once 2 weeks before sacrifying. Relative weights of liver were significantly lowered in the DM group compared to the normal group, whereas those of kidney and heart were significantly increased in the DM group. Supplementation of the Araliaceae water extracts improved reduced liver weights in STZ-induced diabetic rats. Blood glucose level was significantly higher in the DM group than in the normal group, whereas insulin contents were significantly lowered in the DM groups. However, these parameters were normalized in the An, AC and UD supplemented groups, respectively. Blood hemoglobin and $HbA_{1c}$ levels were significantly higher in the DM group than in the normal group. When all of Araliaceae water extracts were supplemented to the diabetic rats lowered hemoglobin and $HbA_{1c}$ levels. Red blood cell, white blood cell and Lymphocyte were significantly higher in the DM group than in the normal group. The supplementation of Araliaceae family water extracts significantly lowered these parameters compared to the DM group. MCV, MCH contents were declined in the DM group, while the supplementation of Aralia elata, Acanthopanacis cortex and Ulmus davidiana water extracts elevated of these contents in STZ-induced diabetic rats. Accordingly, these results indicate that Aralia elata, Aeanthopanacis corex and Ulmus davidiana water extracts would seem to improve the blood biomarkers in STZ-induced diabetic rats.

  • Eleutherococcus senticosus (also called Acanthopanax senticosus), belonging to Araliaceae family, has been used as an important medicinal woody plant. Mature seeds of Eleutherococcus senticosus have rudimentary (extremely immature) zygotic embryos and require a long-term stratification for about 18 months to induce germination. Here, through the methods of endosperm removal and other exogenous treatments, we investigated the factors for inducing rudimentary embryos by in vitro culture, Rudimentary zygotic embryos in seeds were at globular to heart-shaped stage at about $250{\mu}m$ in length just after harvest of fruits. When the seeds without testa were cultured on 1/2 MS (Murashige and Skoog 1962) medium, they did not germinate regardless of medium and sucrose concentrations but the removal of endosperm tissue markedly stimulated the growth of rudimentary zygotic embryos. The embryo reached ear-lier maturation, once when the endosperm surrounding the rudimentary embryos was removed. Rudimentary zygotic embryos developed cotyledons within 3 weeks of culture after endosperm emoval. However, post-mature zygotic embryos failed to germinate though they were morphologically normal, indicating another dormancy of embryos. $GA_3\;(2.0\;\cal{mg/L})$ and/or charcoal ($0.2\%$) treatment rapidly enhanced the germination of zygotic embryos. These results suggest that E. senticosus seeds have double dormancy; i. e. morphological rudimentary dormancy influenced by surrounding endosperm and physiological dormancy after post-maturation of zygotic embryos. Based on the above findings, we established the rapid germination of rudimentary zygotic embryos by in vitro culture of excised seeds with endosperm removal and $GA_3$ treatment.

  • Supercritical fluid extraction (SFE) technique was applied to extract cytotoxic substances from five medicinal plants including Angelica gigas, Angelica acutiloba, Aralia cordata, Spirodela polyrhiza, Bupleurum falcatum, and Acanthopanax sessiliflorus. The cytotoxicities against P388, A549, and HL-60 cell lines were determined for the supercritical carbon dioxide extracts of five plant materials employed and were compared with those of the conventional organic solvent extracts such as n-hexane, $CHCl_{3}$, and MeOH to evaluate the SFE as an alternative method to conventional organic solvent extraction. In most cases, the SFE extracts of plant materials showed enhanced cytotoxicities when compared with those of other organic solvent extracts. In addition, the optimum temperature and pressure of SFE for extraction of the cytotoxic substances were largely affected by both the plant species and the cell lines tested. These results suggested that SFE could be an alternative to the conventional organic solvent method for the selective extraction of cytotoxic compounds from plants.

  • Objectives: This study is an overview of the meta-analysis and systematic review of randomized controlled trials investigating the clinical effectiveness and safety of pharmacopuncture for patients with stroke. Methods: Core electronic databases were searched from their inception to 21 May 2019. A measurement tool to assess systematic reviews (AMSTAR 2) was applied to screen high-quality studies. The results of these studies were summarized, and additional meta-analysis was conducted. The Grading of Recommendations Assessment, Development, and Evaluation (GRADE) was used to evaluate the certainty of evidence. Results: Sixteen studies met eligibility criteria. Four were excluded owing to insufficiency of AMSTAR 2 or low data reliability. The finally selected 12 studies were about pharmacopuncture using either a single herb extract, such as Dengzhan xixin, Sanch, Ginkgo biloba, or Acanthopanax, or a mixture of herbs, such as Compound danshen, Shenxiong, Xingnaojing, or Mailuoning. Most of the patients were from China, with acute ischemic stroke. All the studies using a pharmacopuncture versus a non-pharmacopuncture design reported the significant superiority of pharmacopuncture on every outcome measure. On the other hand, in a few studies, pharmacopuncture was inferior to active control in improving neurological deficit. Few studies reported adverse events. Conclusions: It is difficult to apply the results of this study directly to Korea, because the level of evidence is generally low and the clinical settings and social acceptance of pharmacopuncture therapy differ in Korea and China. Further studies are warranted to confirm the domestic applicability of evidence generated in China and to create evidence that supports the domestic situation.
