본 연구에서는 메밀과 함께 평창의 주요 농산물인 당귀의 새로운 수요를 창출하고 부가가치를 높이기 위하여 당절임 숙성 음료의 효능을 알아보고자 영양성분 조사 및 동물실험을 통하여 혈소판 응집 및 혈액응고에 관한 실험을 수행하였으며 그 결과는 다음과 같다. 영양성분분석에서는 일반적인 성분검사로서 특별한 점이 발견되지는 않았으나 동물실험에서 밝혀진 효능검사는 당귀로 만든 음료가 콜라겐 유도 혈소판 응집반응을 유의성 있게 억제하였다. 일주일간의 짧은 기간 임에도 1%, 10% 및 20%의 음용수로 투여된 실험동물에서 얻어진 혈소판은 콜라겐 유도 혈소판 응집반응을 강력히 억제하였다. 또한 당귀를 음용수에 20%의 용랑을 일주일간의 급성투여로서 혈액응고계에 영향을 미치지 않는 것으로 판단되었다. 결국, 영양성분 및 혈행 개선에 효과가 있다는 것을 알 수 있었다. 이것은 당귀를 이용하여 당절임 추출음료의 개발이 가능하며, 새로운 건강음료가 될 수 있음을 전망하였다. 그러나 제품화하기 위해서는 장기적인 실험 및 다양한 방법의 연구가 추가적으로 이루어져야 한다.

연구배경 : 조직형플라스미노겐활성체는 생리적인 플라스미노겐활성체이므로 혈전의 섬유소에 결합된 플라스미노겐만을 활성화시키는 특이성이 있다고 알려져 있지만, 폐색전증에서 치료목적으로 대량투여하는 경우에도 섬유소에 대한 특이성이 유지되어 전신적인 출혈경향을 유발하지 않는가에 대해서는 논란이 있다. 또한 동량의 약제를 투여하더라도 조직형플라스미노겐활성체의 투여시간에 따라 혈전의 용해효과가 달라진다고 보고되었지만, 이러한 경우에 혈액의 응고기전이 어떠한 영향을 받는지는 명확하지 않아 이를 규명해보고자 본 연구를 시행하였다. 방법 : 실험견에 자가혈병으로 대량의 폐색전증을 유발시킨후 대조군은 특이치료없이, $t-PA_{15}$ 군은 15분동안, 그리고 $t-PA_{180}$군은 3시간에 걸쳐, 조직형플라스미노겐활성체를 체중(kg)당 1mg씩 정맥투여하였다. 그리고 실험과정중 시간에 따라, 실험동물의 혈색소치, 적혈구용적, 백혈구수, 혈소판수, 프로트롬빈시간, 활성부분트롬보플라스틴시간, 섬유소원농도, 트롬빈시간, 플라스미노겐 및 ${\alpha}_2$-항플라스민의 농도, 제 V 및 VIII응고인자의 농도, 그리고 섬유소원분해산물의 농도를 측정하였다. 결과: 1) 일반혈액검사소견근 세 군간에 유의한 차이가 없었다. 그러나 실험과정중 혈색소치와 적혈구용적 및 혈소판수는 감소하고, 백혈구수는 계속 증가하는 경향을 보였다. 2) 프로트롬빈시간, 활성부분트롬보플라스틴시간 및 트롬빈시간은 $t-PA_{15}$군이 치료후 15분~60분 사이에, $t-PA_{180}$군은 치료후 30분~180분 사이에 연장되었다가 정상으로 회복되었다. 3) 섬유소원농도 ${\alpha}_2$-항플라스민의 농도, 제 V 및 VIII응고인자의 농도는 $t-PA_{15}$군 및 $t-PA_{180}$ 군에서 모두 감소하였으나 $t-PA_{15}$군은 $t-PA_{180}$군에 비해 조기에 회복되는 양상을 보였고 플라스미노겐의 농도는 급격히 증가하였다가 회복되는 양상을 보였다. 4) 섬유소원분해산물의 농도는 폐색전후 증가하였고, $t-PA_{15}$군 및 $t-PA_{180}$ 군에서는 조직형플라스미노겐활성체 투여후 더욱 증가하였는데 $t-PA_{180}$군에서 더 현저하였다. 결론 : 폐색전증에서 치료목적으로 대량의 조직형플라스미노겐활성체를 투여하는 경우, 약제의 투여시간이 180분일때보다는 투여시간이 15분일때 출혈이 발생할 가능성이 적다. 따라서 동량의 조직형플라스미노겐활성체를 투여하더라도 약제의 투여시간을 달리함으로써 출혈의 부작용을 줄일 수 있을 것이다.

잡곡류의 항혈전작용을 조사하기 위해 국내산 11종의 잡곡으로부터 80% 에탄올 추출물을 얻어 혈액응고저해활성을 thrombin time (TT)법으로 측정한 결과, 황금찰수수의 에탄올 추출물이 가장 높은 혈액응고저해활성을 보였으며, 뒤이어 청차조 유래의 에탄올 추출물도 혈액응고저해활성을 보였다. 황금찰수수의 에탄올 추출물을 n-hexane, methylene chloride, ethyl acetate 및 n-butanol로 분획하였을 때, 대부분의 TT-저해활성은 hexane과 methylene chloride 분획에 분포하였으며, 이들 분획의 활성은 동일 농도의 aspirin (최종 농도 480 ${\mu}g/ml$)보다 더 높은 것으로 나타났다. 또한 황금찰수수의 에탄올 추출물의 혈액응고저해활성은 activated partial thromboplastin time (APTT)법 및 prothrombin time (PT)법으로도 확인되었다. 이때 APTT-저해활성은 hexane 및 methylene chloride분획에 주로 분포하였으나 PT-저해활성은 hexane 분획에 주로 분포하였다. 이들 분획들의 APTT-저해활성 및 PT-저해활성은 warfarin (최종농도 3.13 mg/ml) 보다 더 높은 것으로 확인되었다. 황금찰수수 유래 에탄올 추출물의 TT-저해활성은 열 안정성 및 pH 안정성이 매우 우수하였다. 한편, 이와 같은 황금찰수수 유래 에탄올추출물, hexane 분획 및 methylene chloride 분획의 경우는 피브린 응괴를 가용화할 수 있는 피브린용해활성을 지닌 것으로 나타났다. 이러한 결과들은 황금찰수수가 혈액응고저해활성과 혈전용해활성을 지니고 있음을 보여주며, 아울러 항혈전 식이요법의 소재가 될 수 있음을 시사한다.

In order to find potential anticancer agents, we extracted pheophytin in the silkworm feces from various larval stages by water, chloroform and methanol extraction. The cytotoxicity of the pheophytin extracts of various silkworm feces was measured in the CT-26 cells originated from murine metastatic colon cancer, by dye uptake assay. The cytotoxicity of those pheophytins in 2nd, 3rd and 4th instars was better than remaining larval stages. The in vitro anticoagulant and fibyinolytic activities of ethanol extract from varietal mulberry leaves, mulberry branches and silkworm feces and pheophytin extracts from silkworm feces obtained at various larval stages were evaluated in order to find effective therapeutic drugs for the treatment of myocardial and cerebral thrombosis. The fibrinolytic activity was tested using the activated partial thromboplastin time (APTT) and thrombin time (TT) was measured for blood clotting activity. With regards to the fibrinolytic system, ethanol extracts of silkworm feces were better than varietal mulberry leaves and mulberry branches. The pheophytin extracts from 7th days of 5th instar contained the highest percentage of pheophytin and good fibrinolytic activity.

An edible marine red alga, Grateloupia filicina, collected from Jeju Island of Korea was hydrolyzed by cheap food-grade carbohydrases (Viscozyme, Celuclast, AMC, Termamyl, and Ultraflo) to investigate its anticoagulant activity. Among the tested enzymatic extracts of G. filicina, a Termamyl extract showed the highest anticoagulant activity. Anion-exchange chromatography on DEAE-cellulose and gel-permeation chromatography on Sepharose-4B were used to purify the active polysaccharide from the crude polysaccharide fraction of G. filicina. The purified sulfated polysaccharide (0.42 sulfate/total sugar) showed ${\sim}1,357kDa$ molecular mass and was comprised mainly of galactose(98%) and 1-2% of glucose. The sample showed potential anticoagulant activity on activated partial thromboplastin time (APTT) thrombin time (TT) assays. The purified G. filicina anticoagulant (GFA) inhibited the coagulation factor X (92%), factor II (82%), and factor VII (68%) of the coagulation cascade, and the molecular interaction (protein-polysaccharide) was highly enhanced in the presence of ATIII (antithrombin III). The dissociation constant of polysaccharide towards serine proteins decreased in the order of FXa (58.9 nM) >FIIa (74.6 nM) >FVII (109.3 nM). The low/less cytotoxicity of the polysaccharide benefits its use in the pharmaceutical industry; however, further studies that would help us to elucidate the mechanism of its activity are needed.

Purpose: There are many patients visited to ED in an alcohol intoxicated state. For these patients, it is difficult to predict by only clinical examination whether he/she would have brain lesion. The purpose of this study is to research whether it is possible to predict brain lesion by only clinical examination findings, with comparing patients with/without actual brain lesions. Methods: A retrospective study was performed at a university hospital for the period 11 months with the medical records. As for the inclusion group, head trauma patients with objectively proved drunk, judging by their blood ethanol concentration, and performed the brain CT were selected. In terms of medical record, Glasgow coma scale (GCS), the presence of neurologic abnormalities, the presence of lesion on brain CT of the patients, were examined. From laboratory results, blood ethanol concentration, platelet count, prothrombin time (PT), activated partial thromboplastin time (aPTT) and glucose concentration were identified. Results: For this study, there were total 80 patients of inclusion group. There was no statistically significant difference in terms of GCS score and neurological examination abnormalities, between the group with brain lesion and the group without brain lesion on brain CT. Conclusion: Alcohol intoxicated patient with head trauma visits the ED, it is not possible to distinguish or determine whether brain lesion exists or not by only clinical findings. In order to check the lesion existence, the image examination, therefore, should be considered and performed.

The present study was designed to clarify whether scuba diving at 5 meters of seawater influences cerebral hemodynamics, hematological and biochemical variables. Twenty healthy young men well trained scuba diving participated in this study. The blood flow velocity in the right and left middle cerebral arteries (L-MCAV and R-MCAV), blood pressure (BP), heart rate (HR), CBC and differential count, prothrombin time (PT), activated partial thromboplastin time (aPTT), biochemical variables, D-dimer and interleukin-8 (IL-8) levels were determined before, immediately after scuba diving for 30 min, and after 30 min of rest (Pre-scuba, Scuba and R-30m, respectively). L-MCAV and R-MCAV tended to increase, but the only significant increase was in L-MCAV in Scuba. SBP and HR significantly declined in R-30m compared with those of Pre-scuba and the Scuba. IL-8 levels were elevated in Scuba and R-30m compared with that of Pre-scuba. In Scuba and R-30m, hematological variables except PT and biochemical parameters excluding glucose and lactic acid did not significantly changed in comparison with those of Pre-scuba. PT level at Scuba and glucose level at R-30m significantly declined in Scuba, while lactate level at R-30m increased compared with each in Pre-scuba. However, PT level at Scuba was within a normal range. These results suggest that scuba diving at 5 m of seawater for 30 min has no adverse effects, is safe and useful for improving health. However, further study must be performed to clarify the mechanism of elevated IL-8 level following scuba diving.
