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.

This study was carried out in order to investigate the anti-oxidant effect of main tonic medicine, Ginseng Radix with combination of other well-known herb medicines such as Rehmammiae Radix Preparat, Astragali, Poria, Aconiti lateralis Preparata Radix, Gecko and Bupleuri Radix. 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.

This study was carried out in order to investigate the anti-oxidative effects of main tonic herb medicine, Ginseng Radix, Rehmammiae Radix Preparat, Astragali Radix, Poria, Aconiti Iateralis Preparata Radix, Gecko and Bupleuri Radix. These herbs were measured on inhibitory activity against 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, Gecko showed the highest anti-oxidant activity among the some herbal medicine and Rehmammiae Radix Preparat 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, Gecko showed the highest anti-oxidant activity among the some herbal medicine and Rehmammiae Radix Preparat showed the lowest anti-oxidant activity. 3.

“Woncheongbyeo” is a new japonica rice (Oryza sativa L.) cultivar developed by mutation techniques from Chu-cheongbyeo. Chucheongbyeo seeds were irradiated with 300 Gy gama ray (83.3 rad/min) emitted from 60Co at a radiation facil-ity of the Korea Atomic
Evaluation of Root Characters Associated with Lodging Tolerance by Seedling Test in Rice
Si-Yong Kang,Won-Ha Yang,Hyun-Tak Shin 韓國作物學會 1999 Korean journal of crop science Vol.44 No.4
Rice seedling test was conducted to check the loging tolerance at ripening stage through evaluating the root characters. Thirteen Korean and foreign rice cultivars with direct seeding adaptable or high quality characteristics were grown in a cell pot and under submerged paddy. The root characters and pushing resistance of rice hill were determined at seedling and ripening stage, respectively. The diameter of crown root at the 7th and 8th leaf stages was thicker in lodging tolerance cultivars than those of others and showed significant-positive correlation with both pushing resistance and crown root diameter of mature plants. Also, the tensile strength of crown root at the 7th and 8th leaf stage showed highly positive correlation with the tensile strength of crown root of mature plants. The number of crown root at 7th leaf stage was significant-positively correlated with that of mature plant. The diameter of seminal root was not significantly correlated with the diameter of crown root throughout the whole growth stage. These results indicate that the diameter, tensile strength and number of crown root associated with root lodging tolerance can be detected with the seedling at about 7th or 8th leaf stage, and the seedling test using the cell pot is an useful and practical method to select lodging tolerant cultivars or lines of rice based on root characters, especially diameter of crown root.

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.
