  • Antioxidative, anticoagulant, and α-glucosidase inhibitory effects of 60% (v/v) ethanolic extract from lotus (Nelumbo nucifera) leaves were investigated in vitro. The yield and polyphenol content of the lotus leaves extract were 35.3±1.1% and 186.2±5.2 ㎍ gallic acid equivalents/mg, respectively. The lotus leaves extract effectively scavenged free and cation radicals, and nitrite in a concentration-dependent manner, and possessed potent reducing power. The lotus leaves extract had remarkable anticoagulant and α-glucosidase inhibitory activities as a function of the extract concentration.

  • Antioxidant, α-glucosidase inhibition, and anticoagulant effects of 80% ethanolic extract from mistletoe (Viscum album var. coloratum) were investigated. The yield and polyphenol content of the mistletoe extract were 30.9±0.4% and 57.6±1.5 mg gallic acid equivalents/g, respectively. The antioxidant effects of the mistletoe extract such as free and cationic radical scavenging ability, nitrite scavenging ability, and reducing power increased in proportion to its concentration. Also the mistletoe extract inhibited the activity of α-glucosidase, and delayed plasma coagulation mainly by inhibiting the extrinsic and common pathways in blood coagulation system.

  • The alkali extraction of anticoagulant from a clove revealed 3-to 6-fold more effective than hot-water extraction. The highest anticoagulant activity was found with 0.1 N NaOH at 7$0^{\circ}C$. The anticoagulant fractions from a clove, EC-2B and EC-2C were separated by alkali extraction, ethanol precipitation, cetavlon treatment, and ultrafiltration. The anticoagulant activities of these two fractions were, respectively, 6.57 and 8.63 times higher than those extracted with hot-water. As of the sensory evaluation, boiled pork added with EC-2B fraction revealed similar sensory acceptability to raw clove material, while EC-2C fraction had low sensory acceptability due to a mild chemical odor. Antibacterial characteristics against pathogenic microorganism of both fractions were confirmed in the control strain. The inhibitory effect of growth by EC-2B was noticed above 0.016% in S. aureus. Also, EC-2C showed the inhibitory effect at 0.004% in both E. cole and S. aureus control strains.

  • 자가 폐동맥 판막을 이용한 대동맥 판막 치환술을 항응고제 복용이 필요없고 내구성이 어느정도 입증되어 늘어나고 있으나, 자가 폐동맥 판막을 이용한 승모판막 치환술은 국내에 보고된 예가 없다. 53세 여자 환자로 류마티스성 승모판막 협차가 및 폐쇄부전, 삼첨판막 폐쇄부전, 만성 심방 세동, 그리고 자회전 관상동맥의 폐색등으로 진단받은 환자에서 자가 폐동맥 판막을 이용한 승모판막 치환술 및 maze 술식, 삼천판막 성형술, 관상동맥 우회수술을 시해하였다. 수술후 특별한 문제없이 회복하였으며 술후 시행한 심초음파 검사상 자가 폐동맥 판막의 이상 소견없이 잘 기능하고 있으며 항응고제 복용없이 잘 지내고 있다.

  • The anticoagulant polysaccharide was screened from the ediable mushrooms. Among them, alkali extract of Ganoderma lucidum showed the highest activity in aPTT. A crude polysaccharide fraction (GL-I) was prepared from the 1N NaOH solution extract of Ganoderma lucidum followed by methanol-reflux, precipitation with ethanol, dialysis and lyophilization. GL-I inhibited the intrinsic pathway in blood coagulation pathway and exhibited concentration dependent anticoagulation effects. The anticoagulant activity of GL-I was decreased greatly by periodate oxidation, but was not changed by pronase digestion. These suggest that carbohydrate moiety may be related to the anticoagulant activity. GL-I consisted of glucose, galactose, fucose, xylose, mannose, arabinose in a molar ratio of 19.3:3.0:2.3:1.3:1.0:0.3. GL-I was partially purified on the DEAE-Toyopearl 650C(GL-IalongrightarrowGL-If) and on the Sephadex G-100(GL-Ic-ilongrightarrowGL-Ic-II).
