  • Background: Panax ginseng (i.e., ginseng) root is extensively used in traditional oriental medicine. It is a modern pharmaceutical reagent for preventing various human diseases such as cancer. Ginsenosidesd-the major active components of ginsengd-exhibit immunomodulatory effects. However, the mechanism and function underlying such effects are not fully elucidated, especially in human monocytes and dendritic cells (DCs). Methods: We investigated the immunomodulatory effect of ginsenosides from Panax ginseng root on $CD14^+$ monocytes purified from human adult peripheral blood mononuclear cells (PBMCs) and on their differentiation into DCs that affect $CD4^+$ T cell activity. Results: After treatment with ginsenoside fractions, monocyte levels of tumor necrosis factor (TNF)-${\alpha}$, interleukin (IL)-6, and IL-10 increased through phosphorylation of extracellular signal-regulated kinase (ERK)1/2 and c-Jun N-terminal kinase (JNK), but not p38 mitogen-activated protein kinase (MAPK). After treatment with ginsenoside fractions, TNF-${\alpha}$ production and phosphorylation of ERK1/2 and JNK decreased in lipopolysaccharide (LPS)-sensitized monocytes.We confirmed that DCs derived from $CD14^+$ monocytes in the presence of ginsenoside fractions (Gin-DCs) contained decreased levels of the costimulatory molecules CD80 and CD86. The expression of these costimulatory molecules decreased in LPS-treated DCs exposed to ginsenoside fractions, compared to their expression in LPS-treated DCs in the absence of ginsenoside fractions. Furthermore, LPS-treated Gin-DCs could not induce proliferation and interferon gamma (IFN-${\gamma}$) production by $CD4^+$ T cells with the coculture of Gin-DCs with $CD4^+$ T cells. Conclusion: These results suggest that ginsenoside fractions from the ginseng root suppress cytokine production and maturation of LPS-treated DCs and downregulate $CD4^+$ T cells.

  • A new cold tolerant germplasm resource named glutinous rice 89-1 (Gr89-1, Oryza sativa L.) can overwinter using axillary buds, with these buds being ratooned the following year. The overwintering seedling rate (OSR) is an important factor for evaluating cold tolerance. Many quantitative trait loci (QTLs) controlling cold tolerance at different growth stages in rice have been identified, with some of these QTLs being successfully cloned. However, no QTLs conferring to the OSR trait have been located in the perennial O. sativa L. To identify QTLs associated with OSR and to evaluate cold tolerance. 286 $F_{12}$ recombinant inbred lines (RILs) derived from a cross between the cold tolerant variety Gr89-1 and cold sensitive variety Shuhui527 (SH527) were used. A total of 198 polymorphic simple sequence repeat (SSR) markers that were distributed uniformly on 12 chromosomes were used to construct the linkage map. The gene ontology (GO) annotation of the major QTL was performed through the rice genome annotation project system. Three main-effect QTLs (qOSR2, qOSR3, and qOSR8) were detected and mapped on chromosomes 2, 3, and 8, respectively. These QTLs were located in the interval of RM14208 (35,160,202 base pairs (bp))-RM208 (35,520,147 bp), RM218 (8,375,236 bp)-RM232 (9,755,778 bp), and RM5891 (24,626,930 bp)-RM23608 (25,355,519 bp), and explained 19.6%, 9.3%, and 11.8% of the phenotypic variations, respectively. The qOSR2 QTL displayed the largest effect, with a logarithm of odds score (LOD) of 5.5. A total of 47 candidate genes on the qOSR2 locus were associated with 219 GO terms. Among these candidate genes, 11 were related to cell membrane, 7 were associated with cold stress, and 3 were involved in response to stress and biotic stimulus. OsPIP1;3 was the only one candidate gene related to stress, biotic stimulus, cold stress, and encoding a cell membrane protein. After QTL mapping, a total of three main-effect QTLs-qOSR2, qOSR3, and qOSR8-were detected on chromosomes 2, 3, and 8, respectively. Among these, qOSR2 explained the highest phenotypic variance. All the QTLs elite traits come from the cold resistance parent Gr89-1. OsPIP1;3 might be a candidate gene of qOSR2.

  • 쌀가루제품은 밀가루 제품에 비하여 알레르기 유발율이 낮으므로, 영유아용 제품으로 개발될 수 있는 가능성이 크다. 특히, 영유아용 식품은 치아발달이 미숙한 영유아에 적합하도록 침에 의해서 쉽게 녹여 삼킬 수 있어야 하는데, 본 연구에서 개발된 팽화쌀과자는 이러한 특성을 모두 만족하고 있다. 본 연구에서는 쌀가루로부터 쌀압출물을 제조한 후 팽화시켜 다공질이 많은 구조를 갖는 쌀과자를 제조하였다. 팽화쌀과자의 팽화율은 1.8배이었으며, 경도는 대조군으로 연구된 Graduates 및 Little과 유의적 차이를 보이지 않았다. 팽화쌀과자의 수분흡수량은 상대습도가 증가함에 따라 증가하였으며 수분 흡수속도는 상대습도 30-40% 구간에서 0.0024 mg/hr로 가장 낮았다. 본 연구에서 개발된 팽화쌀과자는 기존 쌀가공품이 보이는 딱딱한 물성을 다공성의 구조의 형성을 통하여 개선하였으며, 이는 영 유아의 씹힘과 삼킴에 부담을 줄이며 저작운동을 유도하여 치아발달에 도움을 제공할 수 있다. 본 연구의 팽화쌀과자와 같은 팽화쌀제품의 개발을 통하여 기존에 밥, 떡, 주류 중심의 쌀제품에서 탈피하여 쌀가공품의 다양화에 이바지할 수 있다.

  • Mutation breeding is the useful tool to improve agronomic traits in various crop species. Soybean is most important crop and is rich in protein and oil contents. Despite of the importance as economic value and various genetic resource of soybean, there have been limited studies of genetic relationship among mutant resources through radiation breeding. In this study, the agronomical phenotype for selecting various genetic resources was evaluated in 528 soybean mutant lines. As a result, 210 soybean mutants with their original cultivars were selected with various traits. We named 210 selected lines as Mutant Diversity Pool (MDP). The genetic diversity and the relationship of the MDP were investigated using TRAP and TE-TRAP markers. In TRAP analysis, sixteen primer combination (PC)s were used and a total of 551 fragments were amplified. The highest (84.00%) and the lowest (32.35%) polymorphism levels were showed in PC MIR157B+Ga5 and B14G14B+Ga3, respectively. The mean of PIC values was 0.15 ranging from 0.07 in B14G14B+Sa12 to 0.23 in MIR157B+Sa4. Phylogenetic and population structure analysis indicated that the 210 MDP lines dispersed to four groups among the wild types and their mutants. The highest genetic diversity among populations was observed between lines Paldal and 523-7 (Fst=0.409), whereas the lowest genetic diversity was between population KAS360-22 and 94seori (Fst=0.065). AMOVA showed 11.583 (21.0%) and 43.532 (79.0%) variations in inter and intra mutant population, respectively. Overall, the genetic similarity of each intra mutant populations was closer than that of inter mutant population. A total of 408 fragments were amplified in the 210 MDP using twelve PCs of TE-TRAP markers that were obtained from a combination of three TIR sequence of transposable elements (MITE-stowaway; M-s, MITE-tourist; M-t, PONG). The highest (77.42%) and the lowest (56.00%) polymorphism levels were showed in PONG+Sa4 and PONG+Sa12, respectively. The mean of PIC values was 0.15 ranging from 0.09 in M-s+Sa4 and M-s+Ga5 to 0.21 in M-t+Ga5. AMOVA of M-s showed 2.209 (20%) and 8.957 (80%) variations in inter and intra mutant population, respectively. AMOVA of M-t showed 2.766 (18%) and 12.385 (82%) variations in inter and intra mutant population, respectively. AMOVA of PONG showed 3.151 (29%) and 7.646 (71%) variations in inter and intra mutant population, respectively. According to our study, the PONG had higher inter mutant population and lower intra mutant population. This mean was that for aspect of radiation sensitivity, M-s and M-t showed higher mobility than that of PONG. Our results suggest that the TRAP and the TE-TRAP markers may be useful for assessing the genetic diversity and relationship among soybean MDP and help to improve our knowledge of soybean mutation/radiation breeding.

  • 뇌신경 질환의 주요 원인이 되는 것으로 알려진 미세아교세포의 과도한 활성화에 의한 신경염증반응에서 풀무치 에탄올 추출물이 미세아교세포의 염증 반응에 미치는 영향을 검토하였다. 미세아교세포의 활성화를 유도하기 위해 LPS를 사용하였으며, LPS 처리에 의해 신경염증반응의 지표인 NO의 생성량과 이들을 조절하는 iNOS, COX-2의 발현이 증가됨을 확인 할 수 있었다. 그러나 풀무치 에탄올 추출물을 1시간 전처리 한 후 LPS를 처리한 경우 추출물의 농도에 의존적으로 이들의 발현량이 현저히 감소되는 것을 확인 하였다. 또한 LPS 처리로 인해 분비되는 염증성 cytokine들의 생성량도 풀무치 에탄올 추출물에 의해 현저히 억제 됨을 확인 할 수 있었다. 따라서 본 연구의 결과는 미세아교세포의 과도한 활성화로 인해 발생되는 뇌 신경질환의 치료 소재로서 풀무치 에탄올 추출물의 활성 가능성을 제시하였다.

  • The objective of this study was to evaluate the dry matter yield of (DMY) of Italian ryegrass (IRG) forage crop based on two seeding date (September 25 and October 2) in 2017 and 2018, and evaluation of the potential reason of DMY reduction in IRG cultivars grown at Chuncheon, South Korea. Three cultivars of IRG including Kowinearly, Kowinmaster and Hwasan 104 were used in this experiment. The experimental field was designed as a split-split-plot arrangement. The cultivars were harvested on April 26 before the heading stage of both years. In this study, no significant effect (p>0.05) of seeding date has been found on the DMY, whereas the cultivars and year showed a significant effect on the DMY (p<0.05). Except September 25 of 2017, Hwasan 104 indicated significantly lower (p<0.05) DMY than Kowinearly and Kowinmaster in all seeding periods. Though no significant difference (p>0.05) was observed for the DMY between the two seeding dates in 2018, but the DMY was significantly lower (p<0.05) than that of 2017. Lower crude protein (CP) content of Kowinearly was observed on the seeding date of October 2 of 2017, and also in both seeding dates on 2018 (p<0.05). No significant difference (p>0.05) was observed in acid detergent fiber (ADF) between the cultivars on both seeding dates and years. Similarly, no significant difference (p>0.05) was found in neutral detergent fiber (NDF) between the cultivars in 2017. However, Kowinearly showed higher NDF content as compared to Kowinmaster and Hwasan 104 on both seeding dates and years. The seeding date has no significant difference (p>0.05). Thus, considering the extent of DMY in both years, the mean minimum temperature during winter season could be the limiting factor for the DMY of IRG cultivars. However, based on this study, the seeding dates of September 25 and October 2 have no potential effect on the DMY. Thus, on the basis of the current DMY and forge quality parameters, the cultivation Kowinmaster is recommended in Chuncheon.

  • Sasa (S.) quelpaertensis Nakai (Korean name, Jeju-Joritdae), which has anti-oxidative and anti-inflammatory activities, is a type of bamboo grass distributed widely in Jeju Island, Korea. S. quelpaertensis leaves are used for therapeutic purposes in traditional Korean medicine. This study examined the hepatoprotective effects of the S. quelpaertensis ethyl acetate fraction (SQEA) in a mouse model to mimic alcoholic liver damage. The mice were administered orally with 30% alcohol (5 g/kg) once per day with or without SQEA treatments (100 and 200 mg/kg) for 14 days consecutively. Alcohol consumption increased the serum alcohol content and histopathological changes but reduced the liver weight. Moreover, the livers of the alcohol group exhibited the accumulation of malondialdehyde and cytochrome P450 2E1 (CYP2E1), and lipid droplet coating protein perilipin-2. On the other hand, SQEA dose-dependently attenuated the alcohol-induced serum ethanol content and liver histopathological changes but increased the liver weight. Moreover, SQEA attenuated the level of CYP2E1 and inhibited alcohol-induced lipogenesis in the liver via decreased perilipin-2 expression. These results suggest that SQEA can provide a potent way to reduce the liver damage caused by alcohol consumption.
