Abstract
Five fungi (mushrooms), Daedaleopsis styracina, Trichaptum abietium, Coriolus versicolor, Pisolithus tinctorius and Tricholomopsis decora, were screened and examined the fibrinolytic activity and specificity. The extracts of mushrooms showed a level of fibrinolytic activity that was about 3-4 times higher than that of plasmin 1.0 unit. In particular, Pisolithus tinctorius of them showed the greatest enzyme activity (4.71 plasmin unit/mL) by fibrin plate assay, and the highest specificity (1.32 plasmin unit/mL) using chromogenic substrate (N-p-Tosyl-Gly-Pro-Lys p-nitroanilide) by Tricholomopsis decora. And the same molecular mass 54 and 61kDa showing the fibrinolytic activity obtained from all fruiting bodies were confirmed, and it was found that Trichaptum abietium and Tricholomopsis decora have a strong fibrinolytic enzyme with an apparent size of 100 kDa and 84 kDa, respectively on SDS-fibrin zymography activity assay.
혈전용해능을 가진 균류 (버섯류) 5종 Daedaleopsis styracina, Trichaptum abietium, Coriolus versicolor, Pisolithus tinctorius 그리고 Tricholomopsis decora 등을 선발하여 혈전용해효소 활성을 측정하였고, 기질 특이성을 조사하였다. 버섯 추출액을 조제하여 혈전 용해도를 측정한 결과 plasmin 1.0 unit 보다
