Twentyfive plant crude drugs with traditional reputation were selected for the antithrombotic screening. MeOH (80%) extract of each plant was given (500 mg/Kg, p.o.) to mice 1 hr prior to the thrombotic challenge (1.8 mg collagen plus 180 ug epinephrine/Kg, i.v.). Seven extracts (1, 2, 8, 10, 18, 22 and 23) showed either comparable or better recovery than aspirin (50 mg/Kg, p.o.) from paralysis caused by the pulmonary thrombosis. 1, 2, 8, 10, 18, 22 and 23 were fractionated to $CH_2Cl_2$ soluble (fr I) and $H_2O$ soluble (fr II) fractions and each fraction (100 mg/Kg, p.o.) was also tested. Mice treated with fr I of 2 (Angelica koreana), 10 (Corydalis spp.) or 23 (Schizonepeta tenuifolia) showed higher recovery and lower mortality rates than aspirin (50 mg/Kg, p.o.) treated mice.

Totally 91 strains of wild yeasts were isolated from the humus rich soil in the Bogyong city park of Daejeon city, Korea. Majority of the strains belonged to Cryptococcus spp., which included 11 strains of Cryptococcus aureus. Among them, Kwoniella mangroviensis JSS0500, Candida corydalis JSS0501, Candida bombi JSS0503, Candida multigemmis JSS0504, Cryptococcus dimennae JSS0506, Cryptococcus saitoi JSS0507, Cryptococcus victoriae JSS0508, Metschnikowia pulcherrima JSS0502, Papiliotrema aurea JSS0505, Debaryomyces vanrijia JSS0509, Occultifur externus JSS0510, Filobasidium floriforme JSS0511 and Yamadazyma scolyti JSS0512 represented newly recorded yeast strains in Korea, and their microbiological characteristics were investigated. All of these unrecorded yeasts showed oval shape and also formed ascospores and pseudomycelia, except for Kwoniella mangroviensis JSS0500, Candida bombi JSS0503, and Metschnikowia pulcherrima JSS0502. Seven strains including Candida corydalis JSS0501 grew in vitamin-free medium, and 4 of the wild yeasts including Cryptococcus victoriae JSS0508 were halotolerant, i.e., capable of growing in 10% NaCl-containing yeast extract-peptone-dextrose (YPD) broth. Debaryomyces vanrijia JSS0509 was found to be a thermophilic yeast that grew at $37^{\circ}C$.
