  • The neuroprotective effect of solvent fraction of native edible plant MK-104 in the mice administered with kainate was evaluated using behavioral sign, neuronal injuries and biomarkers of oxidative stress. Mice, ICR male, were administered with the BFME through a gavage for 4 days consecutively, and on the 3rd day, kainate (450 mg/kg) was i.p. administered. The fraction(400 mg/kg) delayed the onset time of neurobehavioral change (p<0.01), reduced the severity of convulsion and lethality (p<0.05), and restored the level of GSH and lipid peroxidation in brain to control value. A similar protective action was also expressed by fraction-I (200 mg/kg), which showed a prominent protection against the neuronal damage in hippocampal CA1 and CA2 regions (p<0.01) caused by kainate injection. of TBARS value. Based on these results, BFME-I is suggested to contain a functional agent to prevent against oxidative stress in the brain of mice.

  • This study was conducted to investigate the growth responses of Polystichum lepidocaulon as influenced by 4 different shadings(Control, 50%, 70%, 90%). Under 50 or 70% shading, plant height, stipe length, blade length, blade width, and number of spores increased compared with the other shadings, except the number of frond and shoots. The plants grown under control was shown as smaller with more yellowish green leaf color, and under 90% shading the growth was slightly inferior to those under the 50 or 70% shading. Fresh weight and segment area of frond was better in increased shade levels, but they decreased in under 90% shading. Dry weight and segment thickness decreased as shading increased. Chlorophyll contents increased in proportion to lowered light intensity. Thus, 50 or 70% shading of Polystichum lepidocaulon seemed to maintain the highest growth.

  • 요네병은 Mycobacterium avium subspecies paratuberculosis에 의해 발생하며 반추동물에서 만성 쇠약을 일으켜 전세계적으로 양축산업에 커다란 경제적 손실을 일으키는 질병이다. 본 연구에서는 2008년부터 2009년까지 2년동안 의뢰된 총 3,927건의 국가 종축우의 혈청에 대한 요네병의 항체 양성률에 대해 조사한 결과 21두(0.5%)에서 항체 양성을 나타내었으며 이는 국내 일반 농가의 양성률(1.2-16.4%) 보다 현저히 낮은 수준이었다. 또한 연령별 양성률은 2세 미만에서 0.2% (3두), 2-3세에서 0.4% (2두), 3-4세에서 0.7% (3두), 4세 초과에서 0.9% (13두)로 전 연령에서 양성이 나타났으나 연령이 높아짐에 따라 양성률이 증가하는 경향을 보였다. 품종 별로는 젖소는 모두 음성이었으며 한우에서만 양성률 0.6%를 나타내었다.

  • The distribution of Agrimonia gorovoii Rumjantsev in Korea is verified in this study. The species, described as from Primorsky Krai in Russia, was found in Chungcheongnam-do, Gangwon-do, Gyeonggi-do, and Jeollabuk-do provinces and in Incheon, South Korea. The species is characterized by ten stamens, deeply serrated leaflet margins, and long horizontal pilose stems. A Korean name, Gorovoi-jip-sin-na-mul, for the species is newly given, and a taxonomic description of the species and key to four Korea native Agrimonia taxa are presented.

  • Petrorhagia nanteuilii (Burnat) P. W. Ball & Heywood (Caryophyllaceae), native to western Europe and western North Africa and an introduced or alien plant in South America, Australia, and Japan, was newly found in Gyeongsangnam-do, Korea. Petrorhagia is clearly distinguished from other genera by a bract at the base of calyx, which differs from Gypsophila L., and commissures at the sepals, which is different from Dianthus L. Petrorhagia nanteuilii grows on slopes and roadsides, suggesting that it is likely to have been introduced through the installation of green sites and road construction. A precise description, illustration, photographs, and a key to related genera and species is provided.
