  • Many of researches have revealed that human intestinal microbiota is related to health. Several diseases like obesity, diabetes, and hypertension are affected by the microbiota directly and indirectly. So, interventions with food and drug have been tried to change a composition of the microbiota to better condition. However, few natural medicines have elucidated to date. To understand an influence on microbiota by plant materials including Glycyrrhizae Radix, the extract of medicines were administered to mice and the feces were collected before and after the administration. The feces were analyzed by terminal restriction fragment length polymorphism (T-RFLP). The changes in composition of mice gut microbiota were detected and analyzed. The data could be utilized to further study about biological activities of the plant medicines.

  • This study was conducted to develop effective production system in greenhouse for leaves and stems of Angelica acutiloba by using connect pots in 2003 and 2004. Seed germination rate and plant biomass of Angelica acutiloba collected in 2004 were higher than those harvested in 2003. Germination rate of Angelica acutiloba seeds collected in 2003 was 10%, while germination rate of seeds collected in 2004 was above 90%. Especially, plant growth and yield of Angelica acutiloba grown in connect pots sized with 4 ${\times}$ 4 ${\times}$ 5cm(length ${\times}$ width ${\times}$ height) were the highest. These results indicate that leaf and stem production of Angelica acutiloba can be improved by using connect pots and optimizing seed collecting time in greenhouse.

  • 소금기가 있는 토양에서 잘 자라는 염생식물은 우리나라 서해안에 널리 분포하여 자생하고 있다. 하지만, 특수 환경에서 자라는 특성 때문에 생리활성에 대한 연구가 많이 되어 있지 않다. 특히, 염생식물의 장내세균에 대한 영향 연구는 거의 없어 새로운 활용에 대한 기대가 커지고 있다. 관련 생리활성평가를 위한 기초데이터를 얻기 위해 2020년6월 충남 태안, 전북 부안, 전남 무안에서 총16종의 염생식물을 채취하여 RAW264.7세포에 대한 세포독성을 검토하였다. 시료를 30% 에탄올로 추출하여, 농축, 동결건조를 통해 분말로 만든 후, 0.1-100 ug/mL의 농도로 RAW264.7세포에 처리하였다. 24시간 후, MTT법으로 세포독성을 측정한 결과, 총16종 중 갯질경, 좀보리사초, 갯개미자리 추출물에서 세포독성이 확인되었다. 본 연구를 통해 세포 수준에서 안전성이 확보된 시료를 활용하여 장내세균에 대한 영향 등을 검토할 계획이다.

  • In Islamic dietary guidelines, Halal foods are allowed as edible blessed food. Most foods were categorized within halal for Muslims. The main point of Halal food is that foods are clean in every process and based on Halal standard which might be different in each country. Most pancreatic ${\beta}$ cells synthetize, store, and release insulin. Specific molecular, functional as well as ultrastructural traits of pancreatic ${\beta}$ cells could control their insulin secretion properties and survival phentoype. Insulin-secreting pancreatic ${\beta}$-cells are essential regulators of mammalian metabolism. In addition, the pancreatic ${\beta}$ cell plays an important role in the pathogenesis of type 1 and type 2 diabetes as improving glucose homeostasis by preserving, expanding and improving the function of this key cell type. However, the pharmacological effect of halal food has not been unclear yet, especially food habit-dependent diabetes. The aim of the this study was to determine the preventive effect of Iran plants extract (Almond, Garlic, Cumin, Ginkgo biloba, Holy basil, Psyllium, Satureja khuzistanica, Fenugreek, Green tea, Ipomoea betatas, Blueberry) on RINm5F cells and MIN6 cells as pancreatic ${\beta}$ cell line. The cytotoxicity of the extracts of Iran plants on RINm5F cells and MIN6 cells were measured by using MTT assays. The preventive effects of Iran plant extracts were measured by WST-8 cell proliferation assay on streptozotocin (STZ)-induced cell death in MIN6 cells. In presented result showed that all extract of Iran plants (0.01-10mg/ml) did not show cytotoxicity in RINm5F cells and MIN6 cells. Among non-cytotoxic extract, the protective effects could be detect in high dose concentration. These results suggest that the extract of Iran plants may serve as a potential therapy for diabetes.

  • In the original plant of Arisaematis Rhizomas, the features of external and internal shape of Arisaema amurense var. serratum $N_{AKAI}$ and A. amurense $_{MAXIM}$. are as follows. 1. In the external shape of original plant, Arisaema amurense var. serratum $N_{AKAI}$ has high stem, an oval-elliptic leaflet and a serrate leaf margin. But A. amurense $M_{AXIM}$ has a relatively low stem, an upside oval leaflet and no serrate leaf margin. 2. On the herbs character of original plant, Ansaema amurense var. serratum $N_{AKAI}$ is small in height and diameter, but A. amurense $M_{AXIM}$ is relatively large in height and diameter. 3. On the gathered herbs character of original plant, the section of Arisaema amurense var. serratum $N_{AKAI}$ is brightly white, easily spilt and strong scent. But the section of A. amurense $M_{AXIM}$ is thin yellowish brown, not easily spilt and weak scent. Also the grade of gathered herbs, both can be classified by diameter and external scent. 4. In the current herbs character, Korean and Sichuan Province products are irregullar shape and have no scent, Jilin Province products are regular shape. Also, Guangxi Province products are small size and concave in one side, Hebei Province products are irregular size and shape. 5. In internal shape of original plant, epidermal cell of Arisaema amurense var. serratum is very tight. With the except of micro difference in parenchyma cell of cortex, on the whole there are nearly no differences with A. amurense $M_{AXIM}$. Also, samely in the internal shape, according to collecting sites, epidermis exhibits a lot layer in curving state and secreting duct is developed and vascular bundle and exists between parenchyma cell of cortex. In the future, additional study is needed to distinguish herb and effect between same genus-degree of relatedness.

  • Licorice species (Glycyrhiza species) are perennial plants belonging to the Leguminosae family. Licorice is world-widely distributed in Asia, Europe, and the Americas. The licorice species, such as Glycyrhiza uralensis (G. uralensis) and G. glabra, have been widely used in traditional oriental medicine. G. uralensis is found in Central Asia to the northeastern part of China and G. glabra is distributed from southern Europe to the northwestern part of China. These licorice species are characterized by having various pharmacological activities, including anti-oxidant, anti-inflammatory, immune improvement, and anti-tumor effects. In this study, we investigated the comparative anti-inflammatory effects of four licorice varieties (G. glabra L., G. uralensis FISCH., Shinwongam, and Wongam) on LPS-induced inflammatory responses in RAW 264.7 macrophage cell line. We evaluated the cytotoxicity of licorices at various concentrations. In addition, the nitric oxide (NO) production was elucidated by the treatment of licorice.

  • Aldose reductase (AR) plays a central role in the development of the diabetic complications. Eighty one Korean herbal medicines have been investigated for inhibitory activities on AR. Among them, fourteen herbal medicines exhibited a significant inhibitory activity compared with 3,3-tetramethyleneglutaric acid (TMG) as positive control. Particularly, Xanthium strumarium (fruit, whole plant), Ilex cornuta (stem and leaf), Vitex rotundifolia(stem), Sophora flavescens (whole plant), Platycarya stobilacea (flower) showed two times more potent inhibitory activity than 3,3-tetramethyleneglutaric acid (TMG).

  • Glycyrrhizae Radix (GR), commomly known as liquorice, is a medicinal and edible plant widely used in East Asia with its pharmacological properties. Currently, Glycyrrhiza uralensis, G. glabra and G. inflata are used for pharmaceutical purposes in Korea and then the improved Glycyrrhiza varieties, WON-GAM (WG) has been developed by Korea Rural Development Administration. To evaluate equivalence of efficacy, several comparative studies between already-registered species and new cultivars have been conducted. To evaluate equivalence of efficacy, several comparative studies between already-registered species and new cultivars have been conducted. The aim of this study was to evaluate the effect of WG on fecal microbiota in DSS-induced colitis model. Fecal microbiota was analyzed by terminal restriction fragment length polymorphism (T-RFLP). The composition of the fecal microbiota did not show a specific pattern based on experimental groups; however, a tendency toward an increase in the proportion of Lactobacillales was observed. Glycyrrhiza varieties could change composition of fecal microbiota in DSS-induced colitis model. This work was carried out with the support of "Cooperative Research Program for Agriculture Science and Technology Development (Project No. PJ014246022020)" Rural Development Administration.
