A new sesame variety Kangbaek was developed from Yeongnam Agricultural Research Institute in 2004. Cros wasmade by lodging resistant SP9003-3 line to the F1with high yielding capacity, folowed by pedigree selection, yield test and RYT by the sesame breeding team at the National Insti-tute of Crop Science up to 2003. The variety showed higher disease resistance, especially phytophothra disease, and lodging resis-respectively. It's 1000 grains weight was about 2.54 g indicating 0.03 g heavier than that of Yangbaekkae, and it's oil content wasabout 52%. Kangbaek also contained total 7.65mg/g of such lignans as sesamin and sesamolin. The average yield of Kang-baek was 82 kg per 10a at the national-wide regional performance.

강용길 ; 홍시영 김천대학교 2009 김천대학교 논문집 Vol.30 No.-
Neuroreceptors and transporters have an important role in brain function.Parkinson's disease is a common neurodegenerative disorder that is mainly causedby dopaminergic neuron loss in the substantia nigra.Distribution, density, and activity of neuroreceptors and transporters can bevisualized by radiotracers with PET and SPECT.In vivo PET and SPECT imaging of presynaptic dopamine imaing are alreadyapplied to Parkinson's disease and other parkinsonism, and can demonstrate thedopaminergic dysfunction.Dopamine transporter imaging is useful in the diagnosis of Parkinson's diseaseand the most successful technique in the clinical use of neuroreceptor imaging.Recently, several radiopharmaceuticals including 123I-FP-CIT, 99mTc-TRODATand 18F-FP-CIT for dopamine transporter imaging have been approved for theroutine clinical use in several European countries, Taiwan and Korea, respectively.Therefore, In this paper an overview of Parkinson's disease medicines for diag-nosis and radioactive 18F-FP-CIT using a PET/CT imaging has confirmed theusefulness of the clinical use.

These herbs were mixed with Ginseng Radix to measure inhibitory activity lipid peroxidation of linoleic acid mixture and rat liver and hydrogen-giving-temper effect by DPPH. The study showed the following valuable results. 1. In inhibitory activity of water extract against lipid peroxidation of linoleic acid mixture, Ginseng Radix-Gecko compound herbal medicine showed the highest anti-oxidant activity. Ginseng Radix -Rehmammiae Radix Preparat compound herbal medicine showed the lowest anti-oxidant activity when compared with the examined samples. 2. In inhibitory activity of water extract against lipid peroxidation of rat liver, Ginseng Radix-Gecko showed the highest anti-oxidant activity. Ginseng Radix-Rehmammiae Radix Preparat showed the lowest anti-oxidant activity. 3. In hydrogen-giving-temper effect of water extract by DPPH, Ginseng Radix-Gecko compound herbal medicine showed the highest anti-oxidant activity. 4. In the linoleic acid mixture, Ginseng Radix-Gecko compound herbal medicine showed the highest anti-oxidant activity in Butanol fraction. 5. In the lipid peroxidation of rat liver, Ginseng Radix-Gecko compound herbal medicine showed the highest anti-oxidant activity in Butanol fraction. 6. In hydrogen-giving-temper effect of water extract by DPPH, Ginseng Radix-Gecko compound herbal medicine showed the highest anti-oxidant activity in Butanol fraction. From the above results, it was concluded as follows. All the six compound herbal medicine including Ginseng Radix showed the anti-oxidant activity. Especially, Ginseng Radix-Gecko compound herbal medicine showed the highest anti-oxidant activity among them.

In earlier investigations, Perilla frutescens (L.)Britt. cv. Chookyoupjaso (CJC) mutants were obtained following mutagenesis induced by 200 Gy of γ-rays. The aim of this study was to compare the CJC and 6 P. frutescens (L.) Britt. cv. Chookyoupjaso mutant lines (CJMs), with respect to their phytochemical profiles and to evaluate anti-inflammatory properties by selecting the most bioactive CJM. The methanol extracts of CJMs were tested for inhibition of nitric oxide (NO) production in lipopolysaccharide (LPS)-stimulated RAW 264.7 macrophage cells. Among them, CJM-45 showed significant inhibition of NO production. This extract was further partitioned using ethyl acetate (EtOAc), butanol (BuOH), and water. The EtOAc fraction (EF-cjm45) was evaluated for antiinflammatory activities. These results indicated that the EF-cjm45 reduced NO production by inhibiting inducible nitric oxide synthase (iNOS) expression. The EF-cjm45treatment also significantly diminished expression of MCP-1 and IL-6. In the EF-cjm45, perillaketone,isoegomaketone, ursolic acid, kaempferol, and rosmarinic acid were also found. This study reveals the potential therapeutic use of bioactive CJM-45 and justifies the wide application for this plant in traditional medicine.

Genetic diversity and relationship of Hibiscus syriacus L. were analyzed using 127 cultivars and 7 landraces by the amplified fragment length polymorphism (AFLP) and the assessment of morphological characteristics. The AFLP analysis was carried out by using capillary electrophoresis with 28 fluorescent labeled primer combinations. Morphological evaluation was executed by the 11 parameters. A multivariate data analysis was performed using similarity coefficients, Euclidean distance, unweight pair group method with arithmetic averages (UPGMA) clustering method, and principal coordinate analysis (PCoA) of NTSYS-pc program. In the AFLP analysis, a total of 2, 842 bands were produced in the 28 primer sets, and 43.4% (1,236 bands) of them were identified to be polymorphic. Similarity coefficient values ranged between 0.49 and 0.98. Scattered distribution of the 127 cultivars and 7 landraces was identified, and they were divided into three major groups based on PCoA and UPGMA clustering analysis. In the morphological evaluation, Euclidean distance values ranged from 0.28 to 10.32. The distribution showed that there was a little difference compared with the result of AFLP. The pedigrees of several cultivars were cross-correlated using the results of AFLP and morphological analysis.

<P>The genus Cynodon comprises ten species. The objective of this study was to evaluate the genetic diversity of Korean bermudagrasses at the morphological, cytological and molecular levels. Morphological parameters, the nuclear DNA content and ploidy levels were observed in 43 bermudagrass ecotypes. AFLP markers were evaluated to define the genetic diversity, and chromosome counts were made to confirm the inferred cytotypes. Nuclear DNA contents were in the ranges 1.42-1.56, 1.94-2.19, 2.54, and 2.77-2.85 pg/2C for the triploid, tetraploid, pentaploid, and hexaploid accessions, respectively. The inferred cytotypes were triploid (2n = 3x = 27), tetraploid (2n = 4x = 36), pentaploid (2n = 5x = 45), and hexaploid (2n = 6x = 54), but the majority of the collections were tetraploid (81%). Mitotic chromosome counts verified the corresponding ploidy levels. The fast growing fine-textured ecotypes had lower ploidy levels, while the pentaploids and hexaploids were coarse types. The genetic similarity ranged from 0.42 to 0.94 with an average of 0.64. UPGMA cluster analysis and principle coordinate analysis separated the ecotypes into 6 distinct groups. The genetic similarity suggests natural hybridization between the different cytotypes, which could be useful resources for future breeding and genetic studies.</P>
