The aim of this study was to investigate the physiological functionalities of 60 wild mushroom methanol extracts. We determined their fibrinolytic and ${\alpha}-glucosidase$ inhibitory activities. Among them, 11 mushrooms showed fibrinolytic activity. In particular, Armillaria sp. showed the greatest enzyme activity (4.2 plasmin units/ml) in a fibrin plate assay. The fibrinolytic activities of Amanita virosa. Gymnophilus sp. and Lepista nuda were 2.3, and the activities of Amanita citrina and Cortinarius alboviolaceus were 2.1 and 2.0 plasmin units, respectively. In a ${\alpha}-glucosidase$ inhibitory activity test, Naematoloma fasciculare showed the greatest inhibitory activity at 98.5%. The ${\alpha}-glucosidase$ inhibitory activities of Suillus luteus and Gomphidius maculatus were 66.6% and 61.5%, respectively. This study suggests that both Armillaria sp. and N. fasciculare can be used as candidates for the development of new medicine effective to cardiovascular diseases and biofunctional food.

This study was carried out to observe the antioxidative activity, fibrinolytic activity, nitrite savenging ability and adenosine content of three medicinal mushrooms. Among water and ethanol extract of each mushroom, water extract of Inonotus obliquus (Czech) showed the highest antioxidative activity $(57.1{\mu}g/ml)$, nitrite scavenging ability (52.04%), fibrinolytic activity (86.8%) and adenosin content $(94.3{\mu}g/g)$, whereas nitrite scavenging ability of ethanol extract of Phellinus linteus showed higher than that of water extract. Apart from the above statements, water was effective than ethanol as extracting solvent in general. These results suggest that Inonotus obliquus (Czech) showed higher activities such as antioxidative activity, nitrite scavenging ability, fibrinolytic activity and adenosin content and water was effective as solvent except for nitrite scavenging ability.

The purpose of this research is to develop functional food with garlics(Allium sativum var. pekinense) as a healthy food. Fermented garlic broth(FGB)s were prepared with whole bulb of garlics preserved in sugar and sugar syrup, then fermented and aged at room temperature for 36 months. Biological activities of FGBs were tested antibacterial, antioxidative, fibrinolytic activities and analyzed for polyphenol contents. The total polyphenol contents of FGBs in 12~36 month fermented broth(870~885 mg/100 mL of broth) had significantly higher than those of 1~6 months fermented broths(p<0.001). The electron donating abilities(EDAs) and SOD-like activities of 24~36 month fermented broth had significantly higher than those of 1~6 months fermented broths(p<0.05). FGBs had shown strong antibacterial activities against four kinds of pathogenic bacteria(L. monocytogenes, S. aureus, E. coli O157:H7, and Sal. typhimurium). The fibrinolytic activities of 24~36 months fermented broth had more than twice of the fibrinolytic activity of plasmin. FGBs had increasing activities in antibacterial, antioxidative and fibrinolytic activity as the progress of fermentation period. FGBs can be used as natural antioxidant to prevent oxidative damage on normal cells probably because of their antibacterial, antioxidative and fibrinolytic activities.

In this study, we investigated the biological activities of Carthamus tinctorius including antioxidative, fibrinolytic, thrombin inhibitory, ${\alpha}$-glucosidase inhibitory and collagenase inhibitory activities. Carthamus tinctorius, hot water extract was fractionated into hexane, chloroform, ethyl acetate, butanol and water fraction. Each of these was assayed individually. The hot water extract showed high antioxidative activity and thrombin inhibitory activity at 90.17% and 97.10% respectively. In the fraction activity tests, chloroform fraction showed the highest antioxidative activity at 81.85%. The fibrinolytic activity was strong only in the butanol fraction at 0.70 plasmin units/ml. The thrombin inhibitory activities of hexane, ethyl acetate and butanol fractions were 97.35%, 86.74% and 93.18% respectively. In collagenase inhibitory activity test, hexane fraction showed the highest activity at 87.78%. In conclusion, the hot water extract and solvent fractions of Carthamus tinctorius L can be used as a material for the development of biofunctional tea and foods respectively.

Fibrinolytic activity of fermented kimchi and ingredients used for the preparation were assayed by measuring the lysis area on plasminogen-rich fibrin plate. Fermented kimchi and picked fish sauces from changlan, prwan, and anchovy showed the activity, and the activity of pickled fish sauces were high in the order of pickled changlan, picked anchovy(pickled mulchi), and pickled prawn. However, the activity of kimchi may not be attributed to pickled fish sauce because kimchi containing fish sauce did not possess activities were determined from the samples heated for 30min at 100$\circ$C. There was no changes in activities before and after heat treatment indicating the agents may be components other than protein. Since major changes occur during kimchi fermentation were increased sour taste due to production of organic acids such as lactic, citric, oxalic, and succinic acids, the authentic organic acids present were examined for fibrinolytic activities. The results indicates that the major component posses the activity is lactic acid.

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.

Platelet aggregation inhibitory and fibrinolytic activities of water and ethanol extracts from mushrooms were studied. The highest platelet aggregation inhibitory activity was 81.2% in the ethanol extract from fruiting body of Inonotus obliquus ASI 74006 and also were high in the ethanol extract from fruiting bodies of Fomitella fraxinea. The ethanol extract from the mycelia of Agaricus blazei Murill. ASI 1174 showed the strongest fibrinolytic activity as 9.6 unit. However fibrinolytic activities of other mushrooms were low or negligible.

In this study we investigated the biological activities of Crataegi Fructus, including antioxidative, fibrinolytic, $\alpha$-glucosidase inhibitory, and thrombin inhibitory activities. Crataegi Fructus, hot water extract was fractionated into hexane, $CHCLl_3$, ethyl acetate, butanol, and water fractions, and each of these was assayed individually. The water fraction showed the highest extraction yield at 4.08% (w/w). The antioxidative activities of the water, ethyl acetate, and butanol fractions were 31.07%, 45.87%, 50.28%, and 91.74%, respectively. Assays for fibrinolytic activity indicated that only the butanol fraction has significant efficacy at 1.93 plasmin units/ml. Thrombin inhibitory assays indicated that the 10-fold dilutions of the $CHCLl_3$, ethyl acetate, and butanol fractions had inhibitory activities of 34.97%, 41.43%, and 58.10%, respectively. The 10-fold dilutions of the only ethyl acetate fraction demonstrated $\alpha$-glucosidase inhibitory activities of 75.07%. From the above results, we propose that extracts of Crataegi Fructus can be used as a material for the development of biofunctional foods.

Fibrinolytic enzyme is thought to be involved in extracellular matrix remodeling during regeneration. We investigated the expression and characterization fibrinolytic enzyme activity during earthworm tail regeneration. Electrophoretic analysis of fibrinolytic enzymes induced during regeneration revealed that at least seven types of fibrinolytic enzymes were expressed, which had molecular weight of 12, 19, 23, 27, 32, 45 and 58 kDa, respectively. These fibrinolytic enzyme activities were dramatically increased within 1 day after amputation. These activities were maintained by 7 days postamputation, followed by decrease to control level from 14 days after amputation. Alltypes of fibrinolytic enzyme activities were inhibited by treatment of PMSF and aprotinin, and were insensitive to EDTA and exogenous Ca$^{2+}$. These results indicate that the fibrinolytic enzymes are serineproteinase. Other characteristics including specificities for extracellular matrix proteins are under investigation. Based on these results, we are trying to find out the relationship among expression of proteinases, extracellular matrix remodeling, and dedifferentiation, which are believed to be essential processes during regeneration.
