  • The mucilage production and tyrosine content in soy milk cake (SMC) fermented by Bacillus firmus NA-1, Bacillus subtilis GT-D, and B. subtilis KU-A was improved by fortification with 10% defatted soybean flour. The fibrinolytic activity and consistency of the SMC were drastically increased by solid-state fermentation for 1 day. However, the consistency of the fermented SMC gradually decreased during fermentation for 3 days. Furthermore, the tyrosine content of the freeze-dried powder of SMC fermented by three Bacillus sp. was 9 times higher than that of unfermented SMC. The soybean proteins, including the 7S and 11S subunits, were partially digested during alkaline fermentation, producing lower molecular-weight peptides. The fibrinolytic enzyme produced in SMC fermented by B. firmus NA-l and B. subtilis KU-A exhibited higher thermal stability than that of B. subtilis GT-D fermentation. The powder obtained from B. subtilis GT-D fermentation had an ${\alpha}$-amylase activity and lower consistency compared to those of B. firmus NA-1 and B. subtilis KU-A. In addition, this powder contained 6.3% moisture content, 27% crude protein content and 9 units of fibrinolytic activity and proteolytic activity.

  • Extracts of 67 wild mushrooms were tested for their fibrinolytic activities. The extract of Marasmius pulcherripes showed 112% higher increased activity as compared with a positive control, plasmin (0.75 U/ml). Helvella elastica and Psathyrella sp. showed 60% and 49% of activities to that of plasmin, respectively. Three mushrooms such as Lepista sordida, Fomitella fraxinea, and Leucoagaricus rubrotinctus showed 40% of plasmin activity. The other 60 mushroom extracts did not show any fibrinolytic activity.

  • A correlation between fibrinolytic activity and microflora in Korean traditional soybean fermented food was investigated. The fibrinolytic activities of traditional soybean pastes and commercially processed samples were 2.42$\pm$1.01 unit/g and 1.58$\pm$0.98 unit/g, respectively. The cell density of Bacillus in traditional soybean pastes was about 10$^{7}$ CFU/g and its commercially processed one was 10$^{6}$ CFU/g. Acid producing bacteria, fungi and yeast group were higher in commercially processed one. The correlations of fibrinolytic activity and microflora in traditional and commercial Doenjang were positively correlated in Bacillus ($R^2$≒ 0.69), negatively correlated in fungal group ($R^2$≒0.40), and there were no significant correlations in acid forming bacteria and yeast group ($R^2$<0.16). Fibrinolytic activities in Meju and Koji were 6.54$\pm$1.97 unit/g and 1.46$\pm$0.43 unit/g respectively, and were positively correlated with Bacillus. Yeast and acid forming bacteria were grown by 5∼6 decimal induction during fermentation period of Doenjang, but Bacillus, fungal cells and fibrinolytic activity were nearly stable. Results indicate that fibrinolytic activity of Doenjang depends on enzyme induction in Meju or Koji processing by Bacillus, Doenjang fermentation process.

  • The strain KCTC 11629BP, isolated from spontaneously fermented pine needle extract (FPE), showed fibrinolysis activity. The isolated strain was analyzed in physiological and biochemical experiments. Based on 16S rDNA sequencing and phylogenic tree analysis, the strain was identified to be a part of the genus Acetobacter, with Acetobacter senegalensis and Acetobacter tropicalis as the closest phylogenetic neighbors. Based on genotypic and phenotypic results, it was proposed that bacterial strain KCTC 11629BP represents a species of the genus Acetobacter. The strain was thusly named Acetobacter sp. FP1. In conclusion, Acetobacter sp. FP1 isolated from FPE possesses fibrinolytic activity.

  • The aim of this study was to investigate the physiological functionalities of Codonopsis lanceolata, Glycyrrhiza uralensis, Chaenomeles sinensis, Crataegus pinnafida, and their mixtures. We also determined their antioxidative, fibrinolytic, and ${\alpha}-glucosidase$ inhibitory activities. The antioxidative activities of Codonopsis lanceolata, Glycyrrhiza uralensis, Chaenomeles sinensis, and Crataegus pinnafida were 79%, 88.3%, 89.9%, and 89.3% respectively. Their fibrinolytic activities were 0.80plasmin unit/mi, 0.57 plasmin unit/mi, 0.52 plasmin unit/mi, and 0.53 plasmin unit/mi respectively. The ${\alpha}-glucosidase$ inhibitory activity of Codonopsis lanceolata was 25%. The 10-fold diluents of Glycyrrhiza uralensis, Chaenomeles sinensis, and Crataegus pinnafida showed ${\alpha}-glucosidase$ inhibitory activities of 93.6%, 65.3%, and 61.3% respectively. In antioxidative activity tests of the medicinal plants mixtures at various ratios, the mixtures of Glycyrrhiza uralensis, Chaenomeles sinensis, and Crataegus pinnafida with Codonopsis lanceolata showed antioxidative activities of approximately 90%. In fibrinolytic activity tests mixtures(1:1) of Codonopsis lanceolata with Chaenomeles sinensis and Crataegus pinnafida exhibited increases of 23% and 24% in activity respectively. In ${\alpha}-glucosidase$ inhibitory activity tests, a mixture (4:1) of Codonopsis lanceolata and 10-fold diluted Glycyrrhiza uralensis showed an inhibitory activity of 98%, a mixture (3:1) of Codonopsis lanceolata and 10-fold diluted Chaenomeles sinensis showed an inhibitory activity of 69.6%, and a mixture (1:1) of Codonopsis lanceolata and 10-fold diluted Crataegus pinnafida showed an inhibitory activity of 50.2%. In conclusion, the mixtures of Glycyrrhiza uralensis, Chaenomeles sinensis, and Crataegus pinnafida with Codonopsis lanceolata will be used as a material for the development of biofunctional foods.

  • 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.

  • The effect of cordycepin-enriched Cordyceps militaris JLM 0636 ($CM{\alpha}$) and Cordyceps militaris (CM) on fibrinolytic activity was investigated. The bioactive compounds and nutritional materials such as polyphenolic compounds, flavonoids, glutathione, minerals, and fatty acids were also measured. Concentrations of polyphenol compounds, flavonoids, and glutathione were higher in $CM{\alpha}$ than that in CM. The major minerals of both materials were K, Ca, Mg, and Na. The major fatty acids of both materials were linolenic acid, linoleic acid, oleic acid, and palmitic acid. Fibrinolytic activity was higher in $CM{\alpha}$ than that in CM. These results may provide the basic data to understand the fibrinolytic activity and bioactive compounds of $CM{\alpha}$.

  • Objective: This study was undertaken to isolate a fibrin(ogen)olytic enzyme from the snake venom of Gloydius blomhoffii siniticus and to investigate the enzymatic characteristics and hemorrhagic activity of the isolated enzyme as a potential pharmacopuncture agent. Methods: The fibrinolytic enzyme was isolated by using chromatography, sodium dodecyl sulfate-polyacrylamide gel electrophoresis, and fibrin plate assay. The characteristics of the enzyme were determined by using fibrin plate assay, protein hydrolysis analysis, and hemorrhage assay. Its amino acid composition was determined. Results: The fibrin(ogen)olytic enzyme with the molecular weight of 27 kDa (FE-27kDa) isolated from G. b. siniticus venom consisted of two heterogenous disulfide bond-linked polypeptides with the molecular weights of 15 kDa and 18 kDa. When more than $20{\mu}g$ of FE-27kDa was applied on the fibrin plate, fibrinolysis zone was formed as indicating its fibrinolytic activity. The fibrinolytic activity was inhibited completely by phenylmethanesulfonylfluoride (PMSF) and ethylenediaminetetraacetic acid (EDTA) and partially by thiothreitol and cysteine. Metal ions such as $Hg^{2+}$ and $Fe^{2+}$ inhibited the fibrinolytic activity completely, but $Mn^{2+}$ did not. FE-27kDa preferentially hydrolyzed ${\alpha}$-chain of fibrinogen and slowly hydrolyzed ${\beta}$-chain, but did not hydrolyze ${\gamma}$-chain. High-molecular-weight polypeptides of gelatin were hydrolyzed partially into polypeptides with molecular weights of more than 45 kDa. A dosage of more than $10{\mu}g$ of FE-27kDa per mouse was required to induce hemorrhage beneath the skin. Conclusion: FE-27kDa was a serine proteinase consisting of two heterogeneous polypeptides, hydrolyzed fibrin, fibrinogen, and gelatin, and caused hemorrhage beneath the skin of mouse. This study suggests that the potential of FE-27kDa as pharmacopuncture agent should be limited due to low fibrinolytic activity and a possible side effect of hemorrhage.

  • The fibrinolytic activity of aqueous extracts from Korean indigenous insects were studied. Fibrinolytic activity of aqueous extract from 5 insects (larva and adult parts of Meloimorpha japonica, Allomyrina dichotoma, Cetonia pilifera, Apis mellifera) showed 2.7-fold potent than that of plasmin used as a positive control. In addition, the fibrinolytic activity was observed through the degradation products by SDS-PAGE. The extracts efficiently hydrolyzed ${\alpha}-$, ${\beta}-$ and ${\gamma}$ chains of human fibrinogen. This study suggested that aqueous extracts from Korean indigenous insects have potential in developing a useful source of antithrombosis agent(s).

  • The aim of present study is to investigated on the development of the functional doenjang possessing antioxidative and fibrinolytic activity. A strain, BH-23 showing antioxidative and fibrinolytic activity was isolated from traditionally doenjang, and then identified as Bacillus subtilis based on moophological, physiological, and biochemical characteristics, and named as Bacillus subtilis BH-23. The optimal pH level and temperature conditions were 5.0 and $40^{\circ}C$, NaCl concentration was grown well at 15% Antioxidative and fibrinolytic activity of Bacillus subtilis BH-23 was accoidance with growth conditions of the original state. By comparising with traditionally commercialized doenjang, it is prepared with Bacillus subtilis BH-23. The final results evaluated with positive elements rised above the surface such as color, taste and flavor without ammonia. Therefore, it is safe to assume, doenjang has strong market value in the food industry.
