    Glycyrrhizae radix is one of the most frequently prescribed ingredients in Oriental medicine, and Glycyrrhizae radix extract has been shown to exert anti-cancer effects. However, the cellular and molecular mechanisms of programed cell death (apoptosis) by Glycyrrhizae radix are poorly defined. In the present study, it was examined the molecular mechanisms of apoptosis by water extracts of Glycyrrhizae radix (GRW) in human bladder T24 cancer cells. It was found that GRW could inhibit the cell growth of T24 cells in a concentration-dependent manner, which was associated with the induction of apoptotic cell death, as evidenced by the formation of apoptotic bodies, DNA fragmentation and increased populations of annexin-V positive cells. The induction of apoptotic cell death by GRW was connected with an up-regulation of pro-apoptotic Bax protein expression and down-regulation of anti-apoptotic proteins (Bcl-2 and Bcl-xL), and inhibition of apoptosis family proteins (XIAP, cIAP-1 and cIAP-2). In addition, apoptosis-inducing concentrations of GRW induced the activation of caspase-9, an initiator caspase of the mitochondrial-mediated intrinsic pathway, and caspase-3, accompanied by proteolytic degradation of PARP. GRW also induced apoptosis via a death receptor-mediated extrinsic pathway by caspase-8 activation, resulting in the down-regulation of total Bid and suggesting the existence of cross-talk between the extrinsic and intrinsic pathways. Taken together, the present results suggest that GRW may be a potential chemotherapeutic agent for the control of human bladder cancer cells. - COLLAPSE

    This research was performed to identify the anti-inflammatory constituent from the herb of Lycorus lucidus (Lamiaceae). The MeOH extract of this plant material and its two fractions, the lipophilic- (CHCl3 fraction) and the hydrophilic fraction (BuOH fraction), were prepared to test anti-inflammatory activity. For this purpose, the inhibition rate on inducible nitric oxide synthase (iNOS) activity was assessed by determining nitric oxide (NO) formation in lipopolysaccharide (LPS)-induced macrophage 264.7 cells. The CHCl3 fraction that greatly inhibited nitric NO formation was chromatographed to lead the isolation of ursolic acid. Since ursolic acid inhibited NO formation dose dependently in this study, this compound was considered as one of the active constituent responsible for anti-inflammation. However, the activity of rosmarinic acid isolated from the BuOH fraction was weak. - COLLAPSE

    Anti-acetylcholinesterase (anti-AChE) activity and peroxynitrite scavenging activity of Ainsliaea acerifolia (Compositae) were studied to find its anti-Alzheimer’activity. The IC50 was 73.4 ㎍/mL in AChE assay and 8.60 ㎍/mL in peroxynitrite assay. Caffeoylquinic acids that have been reported to have anti-Alzheimer’s activity were analyzed in the leaf- and stem extract by HPLC. Caffeoylquinic acids occupied 25.1% of the leaf extract which was higher than 8.1% of the stem extract. Particularly, the content of 3,5-dicaffeoylquinic acid (145.6 ㎎/g) was highest of the tested caffeoylquinic acids. In addition, the IC50 values of 3,5-dicaffeoylquinic acid were shown to be 3.79 ㎍/mL in peroxynitrite assay and 69.19 ㎍/mL in anti-AChE assay. - COLLAPSE

    The pathological condition of excessive melanogenesis causing freckles, melasma, senile lentigo, pigmented acne scars, and cancer has a critical impact on the wellness of individuals. The mechanism of melanogenesis is related to the expression of melanogenic enzymes. Here, we evaluated the inhibitory effect of pine cone (Pinus densiflora) extracts on melanogenesis. P. densiflora, the Korean Red Pine, is the predominant tree species in the cool, temperate forests of northeast Asia, occurring in pure stands across Korea, Japan, and parts of northern China and Russia. P. densiflora leaves, pollen, and bark have been widely used for traditional medicine, or edible purposes. However, pine cones are rarely used as natural raw materials, although they contain many bioactive phytochemicals. The pine cone ethyl acetate fraction (PEF) showed no toxicity to B16F10 cells at a concentration of less than 100 ㎍/mL. PEF inhibited the expression of microphthalmia- associated transcription factor (MITF), tyrosinase and tyrosinase-related factors in B16F10 cells treated with 3-Isobutyl- 1-methylxanthine (IBMX). These results suggest that pine cones can be used as an effective natural melanogenesis inhibitory agent. - COLLAPSE

    Gastritis is an inflammatory disease involving the stomach and is caused by several factors, including stress, non-steroidal anti-inflammatory drugs such as aspirin, liquor, and Helicobacter pylori. In Korea, Leonurus japonicus Houttuyn (LJW) has been used as traditional medicine for vaginal bleeding, hematuria, and bruise. Previous studies have reported that LJW exhibited hepatoprotective, cardioprotective, and anti-hyperlipidemic effect. However, the effect of the water extract of LJW on gastritis was not elucidated. Thus, we evaluated the anti-gastric effect and genotoxicity of LJW. LJW effectively prevented the degeneration of surface mucous cells and glandular epithelial cells and vascular congestion induced by HCl/EtOH. Micronucleus assay indicated that the rate of micronucleated polychromatic erythrocytes/polychromatic erythrocytes was not significantly different compared that of the control. Further experiments are required to determine the role of LJW in the gastric injury process such as cyclooxygenase signaling pathway and the secretion of mucus in the stomach. - COLLAPSE

    This study was carried out to select the optimal condition for prothallus propagation and sporophyte formation of Leptogramma pozoi (Lag.) Ching subsp. mollissima (Fisch. ex Kunze) Nakaike and to provide basic data for mass production system. In the propagation, 300 ㎎ of prothallus were inoculated in different kinds of medium [1/4, 1/2, Murashige and Skoog (MS), Knop], sucrose (0, 1, 2, 3, 4%), and cultured for 8 weeks. Sporophyte formation studies were carried out by inoculating blended prothallus into artificial soils. The soils were mixed with horticultural substrate, peatmoss, perlite, and decomposed granite at different ratios or only with the horticultural substrate. Then the prothallus was cultivated for 12 weeks to figure out the formation and growth of the sporophytes. The growth and development of prothalli were excellent on MS medium. According to medium components, prothallus growth was favorable in all treatments except 0% sucrose treatment and the highest in 2% sucrose. In the experiment of soil mixtures, sporophyte formation was the highest in the horticultural substrate:perlite 2:1 (v:v) and horticultural substrate:decomposed granite 2:1 (v:v) treatment, and the overall growth was good in the horticultural substrate:decomposed granite 2:1 (v:v) mixed soil. - COLLAPSE

    Various colors of fruit skin and flesh are the most popular commercial criteria for peach classification. In order to breed new red-fleshed peach cultivar, many cross seedlings and generations should be maintained. Therefore it is necessary to develop early selection markers to screen seedlings with target traits to increase breeding efficiency. For the comparison of transcription profiles in peach cultivars differing in flesh color expression, two cDNA libraries were constructed. Differences in gene expression between red-fleshed peach cultivar, ‘Josanghyeoldo’ and white-fleshed peach cultivar, ‘Mibaekdo’ were analyzed by next-generation sequencing (NGS). Expressed sequence tag (EST) of clones from the two cultivars were selected for nucleotide sequence determination and homology searches. Putative single nucleotide polymorphisms (SNP) were screened from peach EST contigs by high resolution melting (HRM) analysis displayed specific difference between 8 red-fleshed peach cultivars and 24 white-fleshed peach cultivars. All 72 pairs of SNPs were discriminated and the HRM profiles of amplicons were established. In the study reported here, the development of SNP markers for distinguishing between red and white fleshed peach cultivars by HRM analysis offers the opportunity to use DNA markers. This SNP marker could be useful for peach marker assisted breeding and provide a good reference for relevant research on molecular mechanisms of color variation in peach cultivars. - COLLAPSE

    This study was conducted with the purpose of examining the suitability of Euphorbia jolkinii Boiss. as cut flower, so that it may be introduced as a new ornamental crop. For this purpose, effect of various holding solutions on vase solution uptake rate, vase life, and relative fresh weight of cut flowering branches of E. jolkinii was examined. After harvest, cut branches were treated with 10, 50, and 100 ㎎·L-1 of 8-hydroxyquinoline sulfate (8-HQS), 0.1 and 0.2 mM of silver thiosulfate (STS), Chrysal, and Floralife. The cut branches of E. jolkinii were placed under the environmental conditions maintained at air temperature of 22.6°C, relative humidity of 45%, and 9/15h photoperiod that was controlled using fluorescent lamps (light intensity of 9.89 µmol·m-2·s-1). A holding solution containing 10 ㎎·L-1 8-HQS was found to be significantly effective for vase solution uptake rate compared to control, 50 ㎎·L-1 8-HQS, and 100 ㎎·L-1 8-HQS treatments. However, no significant difference was found in vase life between the branches treated with 10 ㎎·L-1 8-HQS holding solution and branches of the control group. Increasing holding solution concentrations of STS was found to have negative effect on the vase life of cut E. jolkinii branches. Relative fresh weight of cut E. jolkinii branches were significantly decreased by two commercial holding solutions, Chrysal and Floralife. It is expected that these results would aid further studies on utilization of E. jolkinii as cut flower crop. - COLLAPSE

    Angelica gigas Nakai (AGN) is a perennial herb belonging to the family Apiaceae. Its root has been utilized as a traditional medicine in Korea. Also, it contains decursin (D) and decursinol angelate (DA) as major active components. This study was performed to compare the change in content of active components and antioxidant activity between bolting and non-bolting AGN. Bolting AGN (B1) and non-bolting AGN (NB1) were harvested in the end of August. Additional non-bolting AGN (NB2) was harvested in the end of October. The total weight of B1 was 728.7 g, which was 98.5% of NB2 weight. Next, the AGN root (B1, NB1 and NB2) was divided into main root and lateral root. And the AGN aerial part (B1, NB1) was divided into flower, leaf and stem. The two active components, D and DA, and antioxidant activity were analyzed. The D content of B1 was 0.35–1.33% according to the plant parts and the DA content was 0.29–1.07%. In addition, B1 flower and leaf showed higher antioxidant activity than NB2 roots. The results show that B1 contained 15–56% of total major components compared with NB2 main roots, suggesting that B1 could be used as a potential material. - COLLAPSE

    This study was conducted to nominate optimal ground cover plants eventually enhancing Aronia production in the highland rolling plains. Total number of 17 weed species were observed in Aronia field when no cover plant was applied. Meanwhile, 12, 14, 15 and 16 weed species were observed when kentucky bluegrass, white clover, rattail fescue and ground ivy were used, respectively. Untreated native weed species were 73.6 ㎝ tall before cut, and kentucky bluegrass, white clover, Rattail fescue and ground ivy were 57.5, 36.8, 48.3 and 40.9 ㎝, respectively. Based on plant height before cut, two shortest plants, white clover and ground ivy, were considered effective as ground cover plants in Aronia field. Coverage at 3rd year by cover plants ranged from 85% to 100%. Coverage of uncovered Aronia field by native weed species was 95% while coverage by 4 treatments, kentucky bluegrass, white clover, rattail fescue and ground ivy were 100, 87, 85 and 100%, respectively. Aronia yield per plant at 3rd year was 1,916 g with white clover cover followed by 1,770 g with Rattail fescue, 1,766 g with ground ivy, 1,098 g without cover plants and 931 g with Kentucky Bluegrass. Out results indicated that ground ivy was the best among all treatments based on 3 criteria, (1) short plant architecture, (2) rapid ground covering and (3) better weed control.

    In seven species of Korean Asarum, 44 qualitative and 28 quantitative characters were reviewed taxonomically. Among 44 qualitative characters observed in vegetative and reproductive organs, the states of 27 characters were common in all the seven species. Among 28 quantitative characters, five characters have the same values in all the seven species; the number of cataphyll (2-4), leaf (2), calyx lobe (5), stamen (12) and pistil (6). White spots on adaxial surface of leaf (effectively) distinguished A. maculatum and A. versicolor from the other species. Many long soft hairs on abaxial surface of leaf distinguished A. mandshuricum from other species with short hairs. The glandular hairs on inner surface of calyx tube were divided into 2 types, reflecting the taxonomic relationships between the species: Type 1 has non-stalked glandular hairs (A. maculatum, A. sieboldii and A. sp.), and Type 2 has stalked glandular hairs (A. patens, A. versicolor, A. mandshuricum and A. misandrum). The length, shape, colour of calyx lobe and the extent to which the calyx lobe recurves, as well as the diameter and colour of calyx tube throat, were confirmed to be taxonomically valuable. In the case of glandular hair density on the surface of calyx lobe, A. patens with low density and A. sp. with high density were clearly distinct from all the other species with intermediate hair density. Meanwhile, the stylar protuberance length of A. patens (2.9-3.3 ㎜) was strikingly different from other species (1.4-2.5 ㎜). Additionally, further examination of the identities of A. yeonbyeonense and A. yeonbyeonense var. viridiluteolum is required. - COLLAPSE
