This study investigated the changes of antioxidant compounds and antioxidant activity of sorghum (Sorghum bicolor L. Moench) by drainage methods in poorly drained sloping paddy field. The experimented soils in this study were very poorly drained (VPDP) and imperfectly drained paddy soil (IDP). Two drainage methods namely under pipe drainage (UPD) and open ditch (ODD) were installed within 1-m position at the lower edge of the upper paddy fields. The soil moisture contents of UPD and ODD on VPDP were 18.52±4.58 and 19.01±4.25%, and IDP were 14.87±4.82 and 18.64±3.85%, respectively. Generally, moisture, crude protein, crude fat and crude ash contents were 12.70~14.50, 0.28~7.02, 4.29~5.04, and 1.31~1.93 g/100 ﾠg, and Pﾠ2O5, K, and Ca contents were 206.18~822.84, 424.16~579.36, and 27.78~68.54 mg/100 g, respectively. The total polyphenol, flavonoid and tannin contents, and radical scavenging activity of the ethanolic extracts of sorghum showed significant differences by drainage methods. The total polyphenol, flavonoid, and tannin contents by drainage methods were 28.33~50.26 mg GAE/g, 5.24~17.10 mg CE/g, and 9.32~25.75 mg TAE/g, respectively. The DPPH and ABTS radical scavenging activities were 20.00~38.61 and 34.60~74.73 mg TE/g, respectively. The antioxidant compounds and radical scavenging activity of the sorghum by drainage methods were frequently affected soil water.

Dynamic postural control varies with the environmental context, specific task and intentions of the subject. In this paper, dynamic postural responses against forward and backward perturbations were experimentally determined using motion analysis system, electromyography and accelerometers. Ten young healthy volunteers, stood on a flat platform, were translated in forward and backward directions by an AC servo-motor. Joint angles, ground reaction forces(GRFs), electromyography and acceleration patterns at the heel and the sacrum were measured. The results based on the given perturbation showed that the dynamic postural balance recovery against forward-backward perturbations is achieved in the process of the ankle, the knee and then the hip. Joint flexion is important in the balance recovery against the forward perturbation, but joint extension is important against the backward perturbation. These responses depends on the magnitude and timing of the perturbation. From the present study the accelerometry-system appears to be a promising tool for understanding kinematic accelerative in response to a transient platform perturbation.

구성태,조명수,황재호,변기원,김경식,손인철 한국전통의학연구소 2002 한국전통의학지 Vol.12 No.1

In the present study, we aimed. to consider the name of twelve main Meridian in order to understand the concept of the Meridian system and to applicate acupuncture theory in the clinical field properly and fundamentally. We referred to several literatures on the matter and we found out that the name of present twelve Meridian was not settled until the period of Yellow Emperor's Classic. In the time of Yellow Emperor's Classic, the two theory of Internal Organ and Meridian system were combined and added new theory of 'WoonGi'. The general rule of combination is that the component of name of Meridian consist of 'Hand' or 'Foot', 'three Eum and Yang' and internal organ. The internal organ coupled with the root ki or middle ki of 'three Eum and Yang' and the 'Hand' or 'Foot' depend on the location of internal organ that belongs to meridian. The name of Twelve Meridian is a kind of system formed to analyze the two concepts organically and dynamically. One is material internal organ and the other is immaterial meridian system.

본 연구는 병리조직학적 및 전자현미경적 방법을 통해 양식산 turbot에서 발생하는 irido-like virus의 감염증을 소개하고자 한 것이다. 2003년 6월 전북 고창 소재 육상수조에서 양식중인 turbot치어에서 50∼70%의 대량폐사가 발생하였다. 병어는 사료섭취가 저하되고 힘없이 유영하다 폐사되었으며, 죽기 직전의 어류는 복부가 팽만되고 안구가 돌출되며 체색이 옅어지는 증상을 보였다. 해부학적 조사 결과, 아가미 빈혈과 간이 퇴색되어 있었으며, 특히 비장조직이 심하게 비대되어 있었다. 병어에 대한 조직학적 검사에서 비대 세포를 특징으로 하는 특이 병변이 주로 신장과 비장의 조혈조직에서 관찰되었으며, 아가미, 심장, 위, 장, 간, 췌장, 지방 조직에서도 관찰되었다. 그리고 전자현미경적 관찰 결과, 비대 세포의 세포질내에서 육각형의 지름이 136∼159 ㎚인 Irido-like virus를 관찰할 수 있었다. The high mortality of cultured juvenile turbot, Scophthalmus maximus occurred in Gochang on June, 2003. The diseased fish was lethargic with reduced feed intake. Grossly, these fish showed pale body, abdominal extension and exophthalmia. The dominant internal gross features of diseased fish were severely enlarged spleen, pale gills and or liver. Diseased fish histologically showed basophilic enlarged cells in the kidney, spleen, gill, heart, stomach, intestine, liver, pancreas and adipose tissue. Transmission electron microscopy (TEM) reveled hexagonal virions in the cytoplasm of necrotic cells. The viral particles lead a central electron-dense core and an electron translucent zone, and were 136-159 nm in diameter. These results suggest that the virus belonging to the iridoviridae was responsible for the mortality of cultured juvenile turbot.
