Here we report the protective activity of cultured Acer tegmentosum cell extract against liver damage in rat intentionally instigated by D-galactosamine. Local fat degeneration and infiltration of inflammatory cells were significantly decreased in cultured A. tegmentosum cell extract administered rat. In addition, acutely increased AST, ALT, LDH, ALP activities and lipid peroxidation and lipid content by liver damage were recovered in experimental rat administrated with A. tegmentosum extract. These results showed that cultured A. tegmentosum cell extract has a role in blood enzyme activation and lipid content restoration within damaged rat liver tissues. Moreover expression rate of TNF-α which accelerates inflammation and induces tissue damage and necrosis was significantly decreased. Also activities of antioxidant enzymes were more effectively upregulated comparing to those of the control group induced hepatotoxicity. All data that cultured A. tegmentosum cell extract has a preventive role against liver damages such as inflammation, tissue necrosis in rats by improving activities of blood enzymes, antioxidant enzymes and modulating expression of inflammation factor, suggest that cultured Acer tegmentosum cell extract is an effective medicinal resource for restoration of hepatotoxicity.

This study aims to evaluate the antitumor effect of Adonis multiflora, one of the plants in the Ranunculaceae, on mice to which hepatoma cells were transplanted and to suggest its possibility as a candidate natural substance to replace antitumor drugs. We performed the MTT assay to assess the extract had a decrease in the growth rate of hepatoma cells depending on concentration. In particular, 100 ㎍/㎖ of the extract showed 40% of growth retardation rate. We assessed the autophagy activity to identify the inhibitory autophagy mechanism of tumor cells in the extract. This proved that the activity increases more as the concentration of the extract is higher. We conducted the Western blot test to confirmed the expression of two proteins LC3 and p62. The expression of p62 was in inverse proportion to the concentration of the extract whereas LC3-Ⅱ increased more as the concentration of the extract was higher. This showed that an increase in the autophagy relies on the conentration of the extract. We performed a test to discover the influence of the extracts on hepatoma cells transplanted to mice. The test proved that the extract triggers a significant decrease in the growth rate of tumor cells. Compared to the start of the test, the size of tumor cells with 50, 100 and 200 ㎎/㎏ of the extract respectively increased by 4, 3.7 and 3.5 times whereas in the controlling group by 6.3 times. The size of tumor cells in benign tumor controlling group increased by 3.1 times. This showed a significant decrease in the growth rate of tumor cells compared to the controlling group. We carried out the experiment of influence of the extract on the expression of two proteins LC3 and p62 in the tumor tissue transplanted into mice. The experiment showed that LC3-II increases more as the concentration of the extract is higher. However, there was a rapid decrease in p62 with 200 ㎎/㎏ of the extract compared to the controlling group. In this study, we proved that the autophagy activity of Adonis multiflora extract inhibits the growth of hepatoma cells by in vitro and in vivo experiments. In conclusion, the inhibitory autophagy mechanism of tumor cells in the extract can be used as a new treatment of antitumor.

Arabis glabra is a localized common rhizomatous flowering plant, This plant is often used in Korean traditional systems of medicine as a remedy for blood cleaning, detoxification, abscess, gastrospasm, arthritis, contraction and diarrhea. Generally drugs that are used for arthritis have antinociceptive and anti-inflammatory properties. However, validity of the anti-inflammatory activity has not been scientifically investigated so far. Therefore, the aim of this study was to investigate the anti-inflammatory potential of A. glabra using the ethanolic extract and its sub-fractions. To evaluate the anti-inflammatory effects, we examined the inflammatory mediators such as nitric oxide (NO) and prostaglandin E
) on RAW 264.7macrophages. Our results indicated that hexane and chloroform fraction significantly inhibited the LPS-induced NO and PGE
production in the cells. The hexane fraction inhibitory activity for NO tests with IC
values showed in 21.0 ㎍/㎖. The chloroform fraction inhibitory activity for PGE
tests with IC
values showed in 18.0 ㎍/㎖. These efficacy are expected to be able to present the potential for the development of health functional food for the prevention inflammatory diseases because it has sufficient preventive medical possibilities. Further, it is determined that it is necessary to further study the mechanism of cytokine and protein expression associated with inflammation.

This study describes a preliminary evaluation of the anti-inflammatory activity of Acrosorium yendoi Yamada extracts. A. yendoi Yamada was extracted using 80% ethanol and then fractionated sequentially with n-hexane, ethyl acetate and butanol. To screen for anti-inflammatory agents effectively, we first examined the inhibitory effect of 80% EtOH extract and solvent fractions of A. yendoi Yamada on the production of pro-inflammatory factors and cytokines stimulated with lipopolysaccharide. In addition, we examined the inhibitory effect of 80% EtOH extract and solvent fractions of A. yendoi Yamada on pro-inflammatory mediators (NO, iNOS, PGE
, and COX-2) in RAW 264.7 cells. In the sequential fractions of n-hexane and EtOAc inhibited the NO and PGE
production and the protein level of iNOS and COX-2, and protein expression of pro-inflammatory cytokines (TNF-α, and IL-6). These results suggest that A. yendoi Yamada may have significant effects on inflammatory factors and may be provided as possible anti-inflammatory therapeutic seaweed.

In the present study, we investigated the effect of 70% EtOH extract from Hippophae Rhamnoides L. leaves (HRL) on the anti-obesity effect in 3T3-L1 cells. The effects of HRL on lipid accumulation in 3T3-L1 cells were examined using Oil Red O staining. In addition, we examined the gene expression levels by using RT-PCR and western blot. The results of this analysis showed that 100 ㎍/㎖ HRL significantly increased the inhibition of lipid accumulation by 82.25%; significantly decreased the mRNA expression of sterol regulatory element binding protein-1c (SREBP-1c), peroxisome proliferator-activated receptor γ (PPARγ), CCAAT/enhancer binding proteins α (C/EBPα), and fatty acid synthase (FAS) in 3T3-L1 cells as well as the stimulated protein expression of AMP-activated protein kinase (AMPK); and suppressed the expression level of PPARγ. These results suggest that HRL can prevent adipogenesis through activation of AMPKα and inhibition of adipogenesis transcription factors.

Osteoarthritis (OA) is a degenerative disease characterized by the progressive degradation of joint cartilage and is accompanied by secondary inflammation of synovial membranes. The purpose of this study describes a preliminary evaluation of the anti-inflammatory activity on test material of Litsea japonica. fruit (LJTM) Also, this study was to evaluate the effects of LJTM on the joint cartilage of rat with OA induced by monosodium iodoacetate (MIA). To study for anti-inflammatory agents effectively, we first examined the inhibitory effect of the LJTM on the production of pro-inflammatory factors and cytokines stimulated with lipopolysaccharide. We identified anti-nociceptive effects of the LJTM by using in vivo peripheral and central nervous pain models. In addition, the aim of this study was to evaluate the effects on mRNA expression of MMP-2, -3, -7, -9, -13, TIMP-1 and –2 in cartilage of OA. In the LJTM inhibited production of pro-inflammatory mediators (NO and PGE
) and pro-inflammatory cytokines (TNF-α and IL-6). In cartilage, Expression of MMPs and TIMPs mRNA was suppressed in LJTM treatment group than in the control group. This study suggests that LJTM are potential candidates as anti-inflammation and anti-osteoarthritis agents (painkillers) for the treatment of OA.

In vitro and in vivo experiments using Achyranthis radix and Drynariae rhizoma extracts were conducted. Antioxidant properties were analyzed and the effects on bone, glucose and lipid metabolism were investigated. Drynariae rhizoma (64.67%) obtained higher DPPH radical scavenging activity compared to Achyranthis radix (19.03%). Similar results were obtained in the reducing power. No differences were observed on the ABTS radical scavenging ability and SOD. In contrast, Achyranthis radix (77.60%) has higher chelating ability compared to Drynariae rhizoma (46.21%). In vivo experiments revealed higher plasma TBARS in OVX-DR than in OVX-AR. Opposite result was seen in erythrocyte TBARS. Hepatic, nephritic and erythrocyte enzymes were considered for the antioxidant enzyme activities. GSH-Px and PON of hepatic enzymes were higher in OVX-AR. While the CAT and GR were higher in OVX-DR. SOD, GSH-Px, GR and PON of nephritic enzymes of OVX-DR were higher compared to OVX-AR. Almost similar values were obtained in CAT using both extracts. The OVX treated rats obtained higher CAT and GR in the erythrocyte enzymes compared to SHAM. The SOD of erythrocyte enzymes in OVX-DR was higher compared to OVX-AR. On the other hand, the GSH-Px was higher in OVX-AR.

Garlic (Allium sativum L.) has been used as both food and medicine in many cultures for thousands of years. Garlic cultivars are completely sterile and propagated through vegetative method. Collection of a large number of fertile accessions of these genus is needed to explore genetic variability. In order to investigate genetic variation among Allium species and its possibilities for direct cultivation in Korea, we characterized 12 accessions of A. longicuspis, flowering wild garlic which had collected from Central Asia, the main center of garlic diversity. Most of A. longicuspis accessions showed higher over-wintering and bolting rate, longer scape length and more number of bulbils than Korean landraces cultivar, Danyang and Euiseong, but A. longicuspis accessions exhibited smaller size of bulbs and bulbils. Most accessions of A. longicuspis had more number of cloves per bulb, except K229596 and K248824 than Korean landraces. All the accessions of A. longicuspis from Central Asia had complete bolters having many flowers and topsets in umbel. Further studies of A. longicuspis should focus on securing true seeds through removal of topsets and crosses among accessions to create the genetic variability.

This study was carried out to elucidate the distribution of vascular plants and their usefulness of Mt. Cheongnyangsan (870 m) in Gyeongsangbuk-do. The vascular plants that were collected 16 times 2006 and 2014 consisted a total of 614 taxa; 97 families, 330 genera, 541 species, 3 subspecies, 61 varieties and 9 forms. For the Korean endemic plants, 21 taxa were recorded and 8 taxa of Vulnerable Species (VU) and 5 taxa of Least Concerned species (LC) categorized by the Korean Forest Service as rare plants were investigated in this region. Furthermore, Ⅴ, Ⅳ, Ⅲ degrees of floristic regional indicator plants designated by the Korean Ministry of Environment included 2 taxa, 10 taxa and 18 taxa, respectively. Moreover, four species of distributional interesting plants, Aconitum austro-koreense Koidz., Allium spirale Willd., Dipsacus japonicus Miq. and Pinellia tripartita (Blume) Schott, in Mt. Cheongnyangsan were discovered by this study. Among them, edible, pasturing, medicinal, ornamental, timber, dye, fiber and unknown usefulness plants included 234 taxa, 213 taxa, 174 taxa, 62 taxa, 16 taxa, 12 taxa, 11 taxa and 167 taxa, respectively. In addition, 32 taxa of naturalized plants were observed.

Nonalcoholic fatty liver disease (NAFLD) is a kind of liver inflammation caused by an accumulation of fat in the liver. Patients with NAFLD have an increased risk to develop liver fibrosis, which leads to cirrhosis. To investigate hepatoprotective effects of Agrimonia eupatoria L (A. eupatoria), oleic acid-induced NAFLD in HepG2 cells was used and A. eupatoria was fractionated with ethanol (EtOH), n-hexane, dichloromethane (CH
), ethyl acetate (EtOAc), n-butanol (BuOH), and H
O. Cells treated with the EtOAc fraction showed the highest lipid accumulation inhibiting effect. A. eupatoria also suppressed triglyceride accumulation and inhibited expression of lipid marker gene, such as a peroxisome proliferator activated receptor γ (PPAR-γ). Moreover, another marker, mRNA expression level of peroxisome proliferator activated receptor α (PPAR-α) was significantly increased by in a dose-dependent manner. These results suggest that A. eupatoria is a potent agent for the treatment of NAFLD.

This study was conducted to select native ground cover plants for sod culture in an organic apple orchard by estimating the effect of three native ground cover plants, Glechoma hederacea, Thymus magnus, and Ixeris stolonifera, on the soil coverage, time-periodic weed occurrence, fruit characteristics, and soil chemical properties. The plant height of G. hederace, T. magnus and I. stolonifera were 15.0 ㎝, 13.4 ㎝ and 7.2 ㎝, respectively. The dry weight of G. hederace, T. magnus and I. stolonifera were 463 ㎏/10a, 247 ㎏/10a, and 255 ㎏/10a, respectively. The plant height and dry weight of G. hederacea were higher than in the other species. T. magnus and I. stolonifera having relatively lower soil cover rate during their life cycle produced a lot of weeds in the orchard as compared with the control. In contrast, G. hederacea showed 100 percentage of ground cover in the first year, and maintained high percentage of ground cover in the growing season of ‘Tsugaru’ apple for another 2 years. When the soil was covered with G. hederacea in the orchard for 3 years, the amount of weed was only 114 ㎏/10a and number of weeding was also reduced about 33% compared with control as well as the other species. There were no differences in the tree growth and fruit characteristics between the native ground cover plants and the control; however, positive effects of native ground cover plants on soil chemical properties were found. In G. hederacea, available P
content in soils remarkably increased and was a significant difference among native species. In addition, cation (Ca, Mg and K) content in soils increased by 39% in Ca, 6% in Mg, and 11% in K at G. hederacea compared with control. These results suggest that G. hederacea could be advantageous in terms of reducing the amount of herbicide applied and the labor required for weed control, and controlling soil chemical properties; therefore, it is a good candidate for sod culture in an organic apple orchard.

Balloon flower (Platycodon grandiflorum A. DC.) is a perennial plant of mainly Campanulaceae family, which have been widely used as a food ingredient and herbal medicine in East Asia. Although demands on related products and yearly cultivation area for balloon flower are increasing, diverse fundamental technologies and molecular breeding studies are not very well supported in Platycodons. In this study, 30 random amplification of polymorphic DNA (RAPD) primers were test in an attempt to explore genetic diversities. In addition, sequences information of the actin gene, a well conserved gene encoding a globular protein that forms microfilaments, was retrieved and analyzed. Two actin homologs were recovered; 3.4 kb fragment is a Pg-actin and 1.4 kb fragment is a Pg-actin homolog with 28.6% similarity. We have confirmed that the Pg-actin gene is configured into 4 exons and 3 introns. A single nucleotide polymorphism (SNP), G↔A, was detected on the intron 3, which served as a target for the CAPS marker development. The marker Pg-Actin-Int3 was applied to 32 balloon flower accessions. Balloon flower DNA sequence information generated in this study is expected to contribute to the analysis and molecular breeding and genetic diversity analysis of balloon flowers.

To produce high quality watermelon, three tetraploid watermelon breeding lines (‘SA03-1’, ‘SA06-1’ and ‘SB01-1’) were developed by treatment with different chromosome doubling reagents. To identify the optimal tetraploid inductive conditions, the three watermelon breeding lines were selected by counting the number of doubled chloroplasts in guard cells. Tetraploid induction rates differed depending on the genotypes and treatment with doubling reagents. However, the highest induction rate occurred with 1.0% colchicine (82.2%). These putative tetraploid lines were re-confirmed for ploidy using flow cytometric analysis and chromosome counting. The internode length of the tetraploid breeding lines was different when the leaf size was larger in all three tetraploid lines compared to their diploids. The fruit weight of the tetraploid fruits for ‘SA03-1’ and ‘SB01-1’ was lower than for their diploid, and the rind thickness and total sugar content (°Brix) of tetraploid SB01-1 were significantly different from those of its diploid. Tetraploid lines were sterile, yielded a lower number of seeds per fruit for ‘SA03-1’ (21), ‘SA06-1’ (62), and ‘SB01-1’ (34.7), and the seeds were larger and thicker than those of their diploids. These tetraploid breeding results will be useful for breeding new seedless watermelon cultivars.

The final goal of this research is to develop a botanical biofiltration system, which combines green interior, biofiltering, and automatic irrigation, which can purify indoor air pollutants according to indoor space and the size of biofilter. The biofilter used in this experiment was designed as an integral form of water metering pump, water tank, blower, humidifier, and multi-level planting space in order to be more suitable for indoor space utilization. This study was performed to compare indoor air quality between the space adjacent to a botanical biofilter and the space away from the biofilter (control) without generation of artificial indoor air pollutants, and to evaluate plant growth depending on multiple floors within the biofilter. Each concentration of indoor air pollutants such as TVOCs, monoxide, and dioxide in the space treated with the biofilter was lower than that of control. Dracaena sanderiana ‘Vitoria’ and Epipremnum aureum ‘N Joy’ also showed normal growth responses regardless of multiple floors within the biofilter. Hence, it was confirmed that the wall-typed botanical biofilter suitable for indoor plants was effective for indoor air purification.
