Gold stock could include the U.K. in the European economy by the alternative plan of the problems that it was occurred while nationalizing industry and a company for economic recovery and national profit after the World War Ⅱ and it was wide and came to open in the country of European most. However, the negation was sentenced to it for the reason of the gold stock which the U.K. adopted in European many countries infringing "freedom of the capital movement" at a European court of law. However, I consider gold stock positively to protect it from hostile M&A of the company of the national strategy from the Middle East and an Asian national rich fund recently in France and Germany. If our country looks straight at reality, Urstatut or the agreement of the majority stockholder have a very strict matter assuming the protection of the existing shareholder and must be able to gain the favor if you look by the flow of such world economy.

Objective : 황금의 유방암세포주에 대한 항암효과 및 기전에 대한 연구는 아직 미흡하며, 특히 에스트로젠리셉터를 가지지않은 유방암세포주인 MDA-MB-231에 대한 효과 및 기전에 대한 연구는 아직 발표된바 없어, 이에 대한 연구가 진행되었다. Methods : 인간 유방암세포주 MDA-MB-231 MTT assay를 이용 성장방해비율을 조사하였으며. FACS analysis를 이용 cell cycle analysis를 시행하였고, Western Blot Analysis 및 Annexin V analysis를 시행하였다. Results : MDA-MB-231에 대한 황금의 IC50는 180 ug/ml 이었으며 최대 세포성장억제효과는 $500{\mu}g/ml$로 한약재중 비교적 강한 세포독성을 보여 주었다. 유세포분석 에서 황금 $500{\mu}g/ml$의 농도를 72시간 투여한 경우 세포사멸(Sub Gl) 분율이 대조군의 1.7%에 비해 21%로 높아 현저한 용량의존적인 세포사멸현상을 보여주었으며, 세포사멸을 보다 명확히 규명할 수 있는 Annexin V analysis에서도 황금 $200{\mu}g/ml$농도일때 48시간에서 17%의 뚜렷한 세포사멸효과를 나타내었다. 한편 세포사멸촉진인자인 Bax, 세포사멸실행단백질인자인 caspase 3의 활성과 PARP의 분할은 세포사멸이 세포주기정지와 더불어 세포사멸의 과정에 p53이 관여함을 알 수 있다. 앞으로의 연구는 p53발현이 다른 세포주와 각 단백질의 억제제를 통해 인과적인 관련성을 즘 더 명확히 할 필요가 있어야 할 것으로 생각되어진다. Conclusion : 유방암의 예후에 있어 호르몬치료에 부적절함으로 인해 예후가 나쁜 에스트로젠리셉터 발현이 없는 유방암에 대해서도 황금이 탁월한 항암효과를 보여주고 있으며, 임상적으로 황금단독, 다른 항암약재와의 배합, 그리고 기존의 항암화학요법이나 방사선요법과의 병용투여를 통한 초기 및 진행된 유방암의 치료에 대한 새로운 접근의 실마리를 제공할 것으로 생각된다.

Antigenic localization in Parofonimn iloktsuenensis worm tissues (tegument, intestine and vitelline gland) in different developmental stages of 2 weeks, 3 weeks, 4 weeks, 5 weeks and 33 weeks from albino rats (Sprague-Dawley) infected with P iloktsuenensis was observed by electron microscopy. These worm tissues of different developmental stage of R iloktsuenensis was observed on electromicrograph by immunogold labeling method using R iLoktsuenensis infected rat serum of 10 weeks. Antigenic localization was demonstrated as labeling of gold particles in tissues on electronmicrograph. In tegument, gold particles were labeled on tegumental tissue, generally more numerous on secretory granules in tegumental syncytium 2 weeks than those on the other elder developmental stages, but there was a little variation in antigenicity according to individual worm tissue. In general, antigenicity in tegumental tissue was not strong (gold particles: 0.1-5/1 Mm2). In intestine, a large number of gold particles (15-18/1 Mm2) were labeled in intestinal epithelium. Gold particles were concentrated especially on secretory granules in cytoplasm, and gold particles were labeled not only in cytoplasmic protrusions, but also in intestinal luminal contents. Intencity of labeling of gold particles was not correlated with developmental stage of worms. In vitelline gland, a large number of gold particles were labeled on vitelline globules. The gold particles in vitelline globules (8- 11/1 Mm2) were concentrated in protoplasm among segmental globules . Key words: Pnragonimus iloktsuenensis, immunogold labeling method, tissue antigen ultrastructure.

In order to selection of the suitable soybean varieties, the quality characteristics of meju and doenjang on 4 domestic soybean cultivars(Daeweon, Sodam, Jinpeum and Hwangkeum) were evaluated. Crude protein and lipid content was 26.7∼30.5% and 16.89∼19.31%. The content of total free sugar among 4 soybean cultivars were 4.99∼5.26% and composed mainly stachyose(2.59∼3.51%), raffinose and sucrose. The content of total free sugar of meju were the highest in Jinpeum among 2.10∼2.66% and composed mainly glucose. The lightness of meju lump in Hwangkeum was larger decrease than the others, the redness were higher in Daeweon and Hwangkeum, the yellowness was the highest in Sodam. The lightness of meju powder was the highest in Sodam, the redness was the lowest in Sodam, the yellowness was the highest in Hwangkeum. The chemical composition of doenjang were that : was the highest in Jinpeum among the 7.90∼9.71% crude lipid, in Daeweon among 9.67∼13.50% crude protein, in Sodam among 2739∼3825 mg% Formol nitrogen and in Daeweon among 6.88∼8.36% crude saponin, respectively. The content of total free sugar of doenjang were the highest in Hwangkeum among 1.88∼2.22% and composed mainly fructose and glucose. The lightness and yellowness of doenjang was the highest in Sodam, the redness was the highest in Hwangkeum. Doenjang by Hwangkeum had good score for taste, texture and overall quality in sensory evaluation.

The quality characteristics of Hwanggeumju (a type of traditional Korean rice wine), which has been described in an ancient document (Sangayorok), were investigated. During its fermentation, its pH gradually decreased from 4.23 to 3.96); and after four days of fermentation, its sugar content significantly decreased. After seven days, its alcohol content rapidly increased to 15.8 percent. Its major organic acid is lactic acid, but malic, succinic, citric and acetic acid were also detected in it. The free amino acid analysis showed relatively high alanine, arginine, asparagine, glutamic acid and leucine contents. The sensory evaluation resulted in high scores for color, turbidity and taste.

목적 : 黃芩(황금)과 黃芩(황금)의 주요 flavonoid 성분인 baicalein이 신장세뇨관 상피세포에서 산화제에 의한 apoptosis에 미치는 효과를 살펴보고자 한다. 방법 : 신장세뇨관 상피세포주인 opossum kidney (OK) 세포를 유기산화제인 t-butylhydroperoxide (tBHP)에 노출시켜 apoptosis를 일으킨 후 관련된 변화를 관찰하였다. 결과 : tBHP는 농도에 의존하여 apoptosis를 유발시켰는데, 이러한 효과는 黃芩(황금)과 baicalein에 의해 농도 의존적으로 방지 되었다. tBHP에 의한 OK 세포사는 항산화제인 Trolox와 N-acetylcysteine에 의해 방지 되었다. tBHP는 mitogen-activated protein kinase의 subfamily인 extracellular signal-regulated kinase (ERK)를 활성화시켰다. ERK 억제제인 PD98059와 U0126은 tBHP에 의한 세포 사망을 방지하였다. tBHP에 의한 ERK 활성화는 U0126에 의해 억제되었으나 黃芩(황금)과 baicalein에 의해서는 영향을 받지 않았다. 철착염제인 deferoxamine은 tBHP에 의한 세포 사망과 ERK 활성화를 방지하였다. tBHP에 의한 세포 사망은 casopase 억제제인 BOD-U-FMK와 zDEVD-FMK에 의해 방지되었다. 결론 : 黃芩(황금)은 산화제에 의한 세포 사망을 방지하는데, 이는 kinase 억제, 항산화제 역할 및 철착염제의 작용에 기인하지 않았다. 黃芩(황금)의 이러한 효과는 산화제에 의관 신부전 예방 및 치료제로 개발하는데 이용될 수 있는 가능성을 보였다.

In order to observe the antigenic localization in the tissues of Paragonimus westermani of deve- lopmental stages, immunogoldlabeling method was applied using serum of the cats which were infected with isolated metacercariae from Cambaroides similis. The sectioned worm tissues from orch developmental stage were embedded in Lowicryl HM20 medium, stained with infected semi IgG and protein A gold complex(particle size: 12 nm) and observed by electron microscopy. In the young adult worm tissue of 4 weeks after infection with metacercariae, the gold particles were specifically concentrated on the tegumental syncytium and cytoplasm of the tegumental cells as well as the secretory granules in the parenchymal tissue. The antigenic materials in the adult worm tissue were specifically concentrated on the secretory granules in the parenchymal tissue, the cytoplasm between granules in the vitelline gland and the epithelial lamella in the lumen of the caecum.
